Saharsh Gera

DOI: 10.1201/9781032654812-1

1.1 INTRODUCTION

In contemporary times, the healthcare sector has faced notable challenges, with one of the foremost being the considerable costs linked to maintenance and administration [1]. The wide variety of people involved in the healthcare system—doctors, researchers, practitioners, support workers, management professionals, and patients—only adds to the complexity of the problem [2]. The management and classification of patient data within this complex ecosystem have become important concerns [3, 4]. The prevalence of variations in data structures and workflows across different health-care domains poses a significant obstacle to the smooth transmission of healthcare-related information, hence adding to the total complexity of the issue [5].

Efforts aimed at addressing the management and interchange of health information records have resulted in the establishment and supervision of systems, typically entrusted to third-party entities. Nevertheless, the issues of trust, privacy, and data security have continued to pose ongoing concerns inside these networks [6]. The conventional electronic healthcare recording systems, which frequently depend on third-party supervision, have not adequately met the privacy needs of stakeholders [7]. Consequently, the traditional electronic healthcare model has encountered a dearth of openness owing to the pervasiveness of privacy and data security apprehensions. Emerging technology known as blockchain has recently been discussed as a possible answer to the healthcare industry’s security problems and data heterogeneity [8].

Blockchain technology, with its decentralized database, digital ledger, and peer-to-peer network, is novel [9]. This technique enables the interconnection of several computers through nodes, hence facilitating the secure exchange of information. This technology allows users to securely access authenticated and verifiable medical information through the use of cryptographic measures. People can start transactions and contribute to the blockchain. Cryptographic hash functions are the main tool for creating cryptocurrency and data integration identifiers.

Stakeholders have exhibited hesitancy in participating in collaborative endeavors and exchanging health-related data due to the inherent limitations and security concerns associated with conventional personal health-record-based and electronic health systems for the transmission of health information. The reluctance displayed in this context has resulted in escalated healthcare expenditures, placing a significant strain on both individuals seeking medical care and healthcare professionals. In light of this, scholars and decision-makers have progressively resorted to blockchain technology as a prospective solution. The revolutionary potential of blockchain technology in improving healthcare management systems and enabling a decentralized framework for the exchange of electronic health information (EHI) has been acknowledged by prominent healthcare institutions [10]. According to research, the blockchain market is expected to grow to more than USD 500 million by 2022 [11].

Despite a large amount of research on blockchain technology’s usage in health-care, there is a striking lack in the existing academic literature of a full and systematic review relevant to the different domains of use. There must be a thorough investigation of how blockchain technology can be used in healthcare. As more people have access to smartphones and health apps, a flood of new medical data is being generated every day. This provides new opportunities to reduce healthcare costs and increase uniformity [12].

Nevertheless, a disparity exists between the potential of the existing healthcare system and its actual execution, since healthcare providers frequently fail to fully exploit technological improvements in supply chain management and other relevant domains [13]. Smart healthcare systems have the capacity to overcome these limits by incorporating intelligent equipment, advanced tools, enhanced facilities, and updated organizational frameworks. Furthermore, it is worth noting that these systems have the capability to integrate customer-connected applications, biosensors, and enhanced emergency service systems [14].

In order to optimize network performance, it is imperative to ascertain consensus methods that are appropriate for blockchain networks and their compatibility with infrastructure built on utilizing IoT devices to advance healthcare [15]. Distributed data storage systems (DDSS) can be used to speed up data exchange procedures and so solve the problem of blockchain’s inability to store massive volumes of data [16].

Numerous legal and regulatory actions have been put in place to ensure patient privacy in the healthcare system. Large fines could be levied on EHRs for failing to comply with these criteria, which include stringent security policies for the management, transfer, and storage of patient data [17].

IBM found that over 70% of healthcare executives believe blockchain technology will have a significant influence on various sectors of the healthcare sector. Improvements in healthcare, improved methods for conducting clinical trials, compliance with regulations, and the introduction of decentralized frameworks for sharing electronic health records (EHR) are all included in this list [18]. Because of its superior data security and management at reduced costs, blockchain technology is seeing increased use in health-care management systems for both practical applications and research [8].

There has been a perceptible uptick in academic interest in blockchain-based healthcare systems in recent years. However, it is essential to recognize that there is still little collection and representation of earlier research in this area. Review articles summarize the state of the art and provide an objective assessment of the various research methods currently in use. When it comes to blockchain’s potential applications in healthcare, however, many studies have fallen short of providing a comprehensive assessment. Research questions, specific healthcare applications, and a look at how blockchain is being used in healthcare today are all in the sights of the investigators.

The purpose of this research is to examine this gap by reviewing the relevant scholarly literature. As part of this investigation, we’ll be compiling data on how blockchain technology might be used in healthcare settings. In addition, the results of this research will shed light on where blockchain-based healthcare systems may be headed in the future, what obstacles they may face, and how they may be solved. The study’s primary contribution is the way in which it synthesizes and organizes data on blockchain applications in healthcare.

The potential of blockchain technology in healthcare settings can only be gauged by a comprehensive review that takes into account the SWOT analysis of the technology. (See Figure 1.1.)

FIGURE 1.1 SWOT analysis of blockchain-based healthcare applications.

1.2 BACKGROUND OF BLOCKCHAIN TECHNOLOGY

1.2.1 WHAT EXACTLY IS BLOCKCHAIN?

Blockchain technology has been viewed as a pioneering breakthrough, distinguished by its decentralized architecture and inherent immutability. (See Figure 1.2.) The proposed solution provides a streamlined methodology for effectively overseeing assets and recording transactions within corporate networks. A blockchain is essentially an encrypted, growing list of records, or “blocks,” that are linked to one another in a safe manner. Embedded inside each block are essential transactional data, along with a timestamp that serves as evidence of the precise instant when the block was generated. What is noteworthy is the development of an indissoluble sequence of blocks, whereby each block effectively preserves data pertaining to its antecedent. The inherent interconnection of blockchain transactions renders them immutable, since any attempt to reverse a transaction would need redoing all following blocks, a task that is very difficult to accomplish. The inherent security and immutability of blockchain technology make it a very influential and transformational factor in several sectors.

FIGURE 1.2 Blockchain structure.

1.2.2 BLOCKCHAIN IN HEALTHCARE: ITS IMPORTANCE

There are a number of problems and opportunities in the healthcare industry that have led to the exploration of blockchain-based solutions. In the healthcare sector, blockchain technology has been highlighted by a number of important components.

Enhanced data security measures aim to safeguard sensitive patient information by preventing unwanted access.

Enhanced Interoperability: Ensuring the easy interchange of data across healthcare providers and systems.

The topic of concern is data integrity, which involves the prevention of unauthorized alterations to data and the assurance of the veracity of patient information.

Patient Control: Facilitating patient autonomy in the management of their health data and privacy.

Efficiency refers to the optimization of administrative operations with the aim of minimizing expenses.

The Importance of Clinical Research: Promoting Research Integrity and Transparency.

Ensuring Drug Safety: The Utilization of Pharmaceutical Tracking Systems to Mitigate the Risk of Counterfeit Medications.

Enhancing Supply Chain Transparency to Ensure the Accessibility of Medical Supplies.

The use of telemedicine and remote monitoring technologies has emerged as a means to enhance healthcare accessibility, particularly in distant areas.

Ensuring Compliance with Data Privacy Regulations: Adhering to stringent data privacy requirements.

The mitigation of healthcare fraud: Ensuring the authenticity of claims.

Advocating for Global Health Initiatives: Enhancing Access to Healthcare for Travelers and International Patients.

By effectively addressing urgent problems and promising prospects, blockchain technology may completely revolutionize the healthcare system.

1.2.3 BLOCKCHAIN TECHNOLOGY’S POTENTIAL BENEFITS

The healthcare industry uses blockchain technology to improve transparency, communication, and patient and staff issues [19]. Modern technology is being used to improve health care systems [20]. This section discusses blockchain’s healthcare benefits. (See Figure 1.3.)

FIGURE 1.3 Blockchain technology’s potential benefits.

1.2.3.1 Decentralization

Blockchain is a distributed system that is decentralized. Henry [21] defined block-chain as a ledger with a timestamped record that is protected from fraud and illegal changes by cryptographic techniques. This contrasts with centralized databases. Blockchain decentralization is transferring authority and oversight from a central institution to a distributed network [22]. This solution relies on decentralized storage to improve security and data authentication [23].

The cryptographic hash corresponding to the preceding block, a date and timestamp, and data from transactions make up each system block. Moreover, it comprises exhaustive information regarding all preceding blocks and transactions, thus building a coherent chain or network. The occurrence of any modification to the data contained inside a block initiates a series of interconnected events that have the potential to cause the whole blockchain to become unresponsive. Blockchain systems determine the individuals or entities who possess the authorization to append blocks and provide the mechanisms via which this procedure is executed [24, 25]. According to the source [26], once data is inputted into a designated block, it becomes immutable and resistant to modification, with changes being prohibited.

1.2.3.2 Trust and Transparency

Trust and transparency play crucial roles in the operational dynamics of block-chain technology. The updated blockchain is transmitted to all network participants after a new block is added. Data blocks that include invalid information are rejected and not included on the blockchain. Consensus mechanisms refer to the validation processes that participants use in order to authenticate the correctness of data blocks. Through the use of consensus procedures, individuals are able to efficiently arrive at a shared consensus on the authenticity and reliability of data blocks [27]. Potential users have access to the data captured and saved on the blockchain, making it easy for them to make changes as needed. The openness inherent in blockchain technology serves as a deterrent against unauthorized data alteration or theft [28].

1.2.3.3 Guarantee of Privacy and Security

Blockchain technology provides a strong way to protect transaction data and data contained within a block from a wide range of possible threats, such as those coming from inside or outside the system, as well as those that are hostile or not meant to be harmful. Rules, tools, and security goods and services for information technology (IT) are often used to quickly find, stop, and deal with possible threats. Blockchain privacy pertains to the ability of stakeholders or groups to segregate their data, thereby facilitating identifiable communication and transaction execution but simultaneously ensuring the protection of personal information from being revealed. This feature enables users to maintain compliance through the process of selective disclosure [29, 30].

1.2.3.4 Availability and Robustness

The availability and robustness of blockchain technology stem from its inherent security and decentralized nature. By storing identical blocks of healthcare information throughout the network without a central authority, blockchain eliminates single points of failure [31]. Because there is no centralized authority, all participating nodes’ resources can be used, and many-to-one traffic flows can be eliminated, ensuring the system’s flexibility and resilience. Furthermore, this technological advancement effectively mitigates any potential delays and successfully addresses the problem of a solitary malfunctioning node [32].

1.2.3.5 Verifiability of Stored Data

By preserving data integrity and accuracy, blockchain technology ensures the verifiability of stored data, allowing validation to occur without requiring access to the plaintext records. The capacity just indicated holds considerable importance in the healthcare industry, especially in situations where data verification is required. Instances of such situations encompass the administration of pharmaceutical supply chains and the handling of insurance claims [33]. Digital ledger technology enables seamless verification and unrestricted access to every element of healthcare data across all nodes within the blockchain network. Blockchains have the advantages of ensuring data integrity and facilitating automated synchronization via their inherent ability to self-update at predefined intervals [34].

1.2.3.6 Other

Data integrity is maintained by blockchain technology’s immutability, preventing changes after recording. Thus this characteristic boosts information believability.

Blockchain technology automates procedures, reduces physical documentation, and removes intermediaries, improving operational efficiency. This results in decreased expenses and faster transaction processing. Blockchain technology allows for lifecycle tracking of assets, products, and transactions. This functionality is important for logistics, supply chain management, and provenance monitoring.

Smart contracts are a form of automated agreements that feature the capability to autonomously execute actions. The utilization of this technology leads to a notable decrease in the requirement for intermediaries, hence diminishing the likelihood of emerging complications.

The utilization of blockchain technology facilitates the smooth implementation of international transactions and cooperation, hence eliminating the necessity for currency conversion or intermediaries.

Blockchain technology possesses the capacity to stimulate innovation across many industries through the provision of distinctive solutions and commercial frameworks.

Blockchain technology relies on trust to eliminate the need for centralized oversight and transaction facilitation. Cryptographic verification verifies transaction integrity.

Immutable records are unchangeable data stored on the blockchain. This quality provides data integrity and reliability over time.

The resilience of blockchain technology is attributed to its distributed and redundant network architecture, which effectively mitigates the impact of failures and malicious assaults, hence guaranteeing the dependability of the system.

Cost reductions may be achieved via several means, including reducing dependence on intermediaries, streamlining administrative processes, and using automated systems. These measures have the potential to provide cost efficiencies across different industries.

1.2.4 MODELS FOR THE DEPLOYMENT OF BLOCKCHAIN TECHNOLOGY

Network behaviors and distinctive characteristics allow blockchain networks to be divided into numerous distinct groups. The categorizations presented in this study are derived from the characteristics outlined by Zheng and Alhadhrami [35]. The many blockchain network categories are explored next.

1.2.4.1 Public Blockchain

Blockchain represents a decentralized, accessible digital ledger without central authority.

In the context of a public blockchain, it is imperative to acknowledge that all transactions possess intrinsic transparency and are available to all network nodes.

All network nodes can engage in the consensus procedures of the block-chain in order to authenticate transactions.

In this particular network configuration, the inclusion of nodes does not need explicit authorization, and the identities of those nodes are often undisclosed to other participants.

Public blockchains function on a significant magnitude, whereby nodes provide assistance to the network as well as to one another.

Prominent instances of public blockchains include the cryptocurrencies Bitcoin and Ethereum [36].

1.2.4.2 Permissioned Blockchain

Permissioned blockchains are a specific type of blockchain network that imposes limitations on access and participation, restricting them to a specific group of users.

These blockchains are managed and supervised by organizations or institutions, which necessitate nodes to obtain authorization before joining the network.

The transactions occurring inside these systems are subject to both oversight and regulation.

One notable benefit of permissioned blockchains is the enhanced level of privacy they provide, owing to the need for identification before accessing the network’s information.

One instance that serves as an illustration of this category is the MultiChain platform [37].

1.2.4.3 Consortium Blockchain

A blockchain network is maintained by multiple organizations or corporations.

Consortium blockchains exhibit resemblances to permissioned blockchains, since they are often administered by a consortium or collective of organizations.

In order to become part of the network, nodes are required to pass authentication and authorization procedures.

Consortium blockchains are distinguished by their unique approach to transaction validation, which entails the involvement of a certain set of nodes with predetermined criteria.

The establishment of consensus among validating nodes is a crucial aspect in the generation of new blocks and the completion of transactions.

Consortium blockchains are often used in situations where a certain level of trust is established among members [38].

1.2.4.4 Private Blockchain

Blockchain refers to a decentralized digital ledger system that is restricted to a certain group of participants.

Private blockchains are characterized by their limited access, since they are only available to a particular cohort of users who are often well-known and possess a level of trust among one another.

Enterprises and organizations often use these networks for internal functions, including supply chain management and recordkeeping.

Privacy and control are of utmost importance in private blockchains, since they are not accessible for public engagement.

In contrast to public blockchains, which allow for unrestricted participation, private blockchains exhibit a centralized authority structure that governs network operations.

1.2.4.5 Hybrid Blockchain

Integrating public and private blockchain networks into a so-called hybrid blockchain increases adaptability and customization.

Hybrid blockchains amalgamate components from both public and private blockchains in order to provide a tailored solution.

In the hybrid approach, some components of the blockchain exhibit a public nature, therefore enabling universal accessibility, but other segments possess a private characteristic, thereby imposing restrictions on access.

This methodology enables more adaptability in customizing blockchain networks to meet unique demands, including those related to data confidentiality and visibility.

1.2.4.6 Federated Blockchain

The term “decentralized network” pertains to a system of interconnected blockchain systems that engage in collaboration and resource sharing in order to collectively accomplish a shared objective.

Federated blockchains are overseen by a consortium or federation of entities rather than being subject to the authority of a single institution.

The consortium’s member organizations exercise authority over the network and engage in consensus methods.

This particular kind of blockchain is often used in situations when several organizations are required to engage in collaborative efforts while also maintaining a certain degree of trust and control within the network.

1.2.4.7 Permissionless Blockchain

Blockchain technology is a distributed and decentralized record keeping method that lets anyone take part in deals and verify blocks without needing special permission.

In contrast to permissioned blockchains, which restrict participation to a select group, permissionless blockchains are accessible to any anyone seeking to engage in the network.

Typically, these networks have a decentralized structure and function via the use of consensus methods, enabling members to verify transactions without the need for prior authorization.

Bitcoin and several other publicly traded cryptocurrencies may be classified within this category.

1.2.4.8 Sidechains

Sidechains refer to a concept in blockchain technology where separate blockchains are connected to a main.

Sidechains refer to autonomous blockchains that possess the capability to interact with a central blockchain, often referred to as the mainchain.

Interoperability solutions provide the seamless movement of assets and data between diverse blockchains, hence enhancing the overall functioning and scalability of the blockchain ecosystem.

Sidechains have the potential to mitigate challenges associated with scalability and transaction speed.

The many categories of blockchain networks are designed to accommodate diverse use scenarios and meet the requirements of various organizations. Public blockchains place a higher emphasis on the principles of openness and decentralization, while permissioned and consortium blockchains promote control, authentication, and privacy. Total comprehension of these categories is crucial in the process of ascertaining the most appropriate blockchain network for a particular application or environment. Different types of blockchains, such as public, private, hybrid, and consortium are compared each other in Table 1.1 according to the access mechanisms, consensus methods, use cases, and privacy attributes [35].

TABLE 1.1 Types of blockchain and their properties

Parameters | Public Blockchain | Private Blockchain | Hybrid Blockchain | Consortium Blockchain

Privacy | Less privacy | Improved privacy | Customized privacy may be due to network architecture and design. | Better scalability compared to the public blockchain.
Examples | Ethereum, Bitcoin | R3 Corda, Hyperledger Fabric, Quorum | Quorum | R3 Corda, IBM Blockchain, Hyperledger

1.2.5 BLOCKCHAIN CONSENSUS MECHANISMS

The validation process inside the realm of blockchain is well recognized as mining, in particular, proof-of-work (PoW) algorithms and other consensus methods [39]. (See Figure 1.4.) The standard protocol incorporates a consensus algorithm that oversees the verification of blocks and also delineates the guidelines that participating nodes must adhere to during the validation process. Getting all validating nodes to agree that a block should be added to the blockchain is the basic goal of the consensus protocol [38, 40].

FIGURE 1.4 Blockchain’s layered architecture.

Several methods of consensus were developed to improve blockchain transaction validation reliability. In the next part, we provide a complete overview of three fundamental protocols commonly seen in academic literature.

The Proof-of-Work (PoW) technique requires miners, or nodes, who partake in a competitive process with the objective of solving a cryptographic puzzle. The primary node that successfully identifies a solution is endowed with the power to verify the block and create a following one that includes the transaction. Bitcoin’s proof-of-work (PoW) rewards miners who complete the process [39].

In Proof-of-Stake (PoS) consensus, validators are selected from the network pool based on their token holdings, with their selection probability being directly correlated to their currency holdings. Consequently, a node with a higher quantity of coins is more likely to engage in block validation and, consequently in verifying the authenticity of the block [41, 42].

The Practical Byzantine Fault Tolerance (PBFT) consensus technique considers client and server nodes. The PBFT technique validates transactions in prescribed steps. Requests from client nodes to server nodes start the process. Subsequently, the server node disseminates the transaction to other server nodes, which collaborate to determine its legitimacy. Upon approval of the transaction by a server node, it transmits a readiness message to the remaining server nodes. After a sufficient number of nodes have verified the transaction, it transitions into a state known as “confirmation alert.” Subsequently, each confirmed node disseminates a message across the network to authenticate its actions. Finally, the node that initiated the transaction receives a response indicating the validation status of the transaction [20, 42].

1.2.6 SMART CONTRACTS ON BLOCKCHAIN

The emergence of contract technology became apparent in the context of Blockchain 2.0, specifically inside the Ethereum framework [43]. The adoption of the Solidity programming language has made a substantial impact on the development of block-chain-based apps, leading to a major increase in their overall acceptance and utilization. A smart contract can be defined as a mechanism that enables the automated and computerized governance of a transaction [22, 44].

Smart contracts can improve security, reliability, and ease in numerous transactions, including those involving cryptocurrencies and other assets. Smart contracts activate when preset conditions are met. The capacity just mentioned e helps identify and resolve irregularities or breaches automatically, increasing transaction integrity [45, 46].

Smart contracts provide a comparable degree of adaptability to digital transactions, similar to the functions fulfilled by legal agreements in conventional settings. The increased precision and automation of processes significantly contribute to the optimization and reliability of the transactional environment.

1.3 RESEARCH METHODOLOGY

2.1 INTRODUCTION

The field of research known as content-based image retrieval (CBIR) has become more important in the field of computer vision. CBIR has applications in a variety of fields, including image retrieval, image identification, and multimedia retrieval. CBIR systems strive to retrieve images from a huge image library based on their visual content, without relying on written annotations or metadata. The traditional techniques to CBIR frequently depended on handcrafted elements such as color, texture, and shape. However, these features may not effectively reflect the complexity and abstraction of the image content. In spite of this, tremendous progress has been made in CBIR during the past few years as a result of the development of deep learning.

The integration of blockchain technology with CBIR in healthcare addresses these challenges. By utilizing the inherent attributes of blockchain, such as transparency, immutability, and decentralized data storage, this cutting-edge approach ensures that medical images can be securely stored, accessed, and shared with the utmost confidence. Furthermore, it facilitates data traceability, enabling healthcare providers to keep a comprehensive record of who accessed and modified medical images, ensuring data integrity and accountability.

This paper provides an in-depth exploration of the state of the art in content-based image retrieval using blockchain technology in healthcare. Securing data in a content-based image retrieval system using blockchain without compromising privacy (i.e., without using plain text data) is a challenging yet important endeavor. Blockchain technology offers data security through its decentralized, immutable, and transparent ledger system. In hashing and encryption, instead of storing the actual image data on the blockchain, you can store a cryptographic hash or a reference to the image data. The original image data can be stored securely in off-chain storage or a separate data repository. Only authorized parties with the decryption keys can access the original image data. Metadata about the image can be stored on the blockchain. This metadata can include information such as the image’s unique identifier, creation date, type, and relevant attributes. This metadata is often used for indexing and retrieval. Blockchain can facilitate access control through smart contracts. You can define rules and permissions on who can access and modify data. Only authorized users with the proper cryptographic keys can execute these smart contracts to access or update data. Storing the actual image data in a decentralized file storage system (e.g., IPFS or a blockchain-based storage solution) can add an extra layer of security. These systems break the image into small pieces, store them across multiple nodes, and require cryptographic keys for reassembly. Blockchain’s immutability and transparency enable tracking and auditing of data access and modifications. Every transaction is recorded in the blockchain, creating an audit trail. Any unauthorized access attempts or data breaches can be easily detected. Zero-knowledge proofs (ZKPs) can be used to verify the authenticity of data without revealing the data itself. For instance, ZKPs can confirm that a particular image meets specific criteria without disclosing the image content. In a healthcare setting, it’s often beneficial to use private or permissioned blockchains where only known participants (hospitals, clinics, authorized researchers) are allowed to join. This reduces the risk of unauthorized access. The image data can be split into multiple fragments and distributed across the blockchain network. This ensures that even if attackers gain access to one fragment, they cannot reconstruct the full image without all the fragments. Cryptographic techniques, such as multi-signature schemes, can be used where multiple parties need to authorize access to the data. This adds an extra layer of security and ensures that no single entity can access the data independently. When transmitting data to and from the blockchain, secure channels with encryption should be used to protect data in transit.

The intricacies of modern healthcare are profoundly reliant on diagnostic imaging, a realm where precision and timeliness are of paramount importance. The digital era has ushered in an abundance of medical imaging data, from X-rays to MRIs and 3D scans, each holding invaluable insights that can expedite diagnosis and treatment. Yet the effective utilization of this data remains an ongoing challenge. CBIR, a technology that leverages image content to retrieve relevant medical images, has the potential to unlock this treasure trove of information.

Enhancing CBIR’s capabilities, 3DCNN steps onto the stage, offering a dynamic approach to feature extraction in 3D images and videos. These neural networks are designed to analyze spatial and temporal features, ideally suited for applications involving video or volumetric data. In the context of healthcare, they promise to provide more accurate, nuanced, and context-aware image retrieval and analysis, which is crucial for precise medical diagnosis and research.

As we navigate this digital healthcare transformation, the importance of data security and integrity cannot be overstated. This is where blockchain technology, often synonymous with data transparency and security, enters the scene. By implementing a blockchain infrastructure, we ensure that medical image data remains tamper-proof, transparent, and auditable, addressing crucial concerns about data privacy and integrity.

This book chapter takes a deep dive into the confluence of these technologies, shedding light on their individual contributions and, more significantly, their combined potential to shape the future of healthcare. It explores how CBIR using 3DCNN and blockchain can enhance diagnostic accuracy, provide data security, and offer a patient-centric approach to healthcare, promising a new era of precision medicine and revolutionizing the way we perceive and harness medical imaging data.

In section 2.2, the related work is described. In section 2.3, the proposed methodology is discussed with the dataset description and the proposed architecture. Section 2.4 deals with results and discussion and section 2.5 with the conclusion and future work.

2.2 RELATED WORKS

The task of content-based image retrieval, often known as CBIR, is an essential one in computer vision and has garnered a great amount of interest over the past few years. Due to its capacity to learn high-level characteristics directly from images, deep learning has recently emerged as a strong technique for CBIR. In particular, convolutional neural networks (CNNs) have been at the forefront of this development. In this literature survey, we cover the state-of-the-art strategies for effective deep-learning-based CBIR. We place a particular emphasis on methods that solve the difficulties of scalability, accuracy, and computational efficiency.

Krizhevsky, Sutskever, and Hinton [1] presented the idea of using deep CNNs for image categorization and established the groundwork for a wide variety of following deep-learning-based CBIR techniques. Simonyan and Zisserman [2] developed the VGGNet architecture with deeper networks and smaller filters. As a result, the accuracy of image recognition tasks, such as CBIR, was significantly improved. [3] presented the Inception architecture, which is characterized by its utilization of several parallel convolutional branches with varying filter sizes. This results in deep CNNs that are both more effective and accurate.

The author of [4] proposed the Fast R-CNN framework for object identification. This framework has the potential to be extended for CBIR by making use of region proposal networks (RPNs), which are designed for effective feature extraction and localization. The author of [5] expanded the Fast R-CNN framework by introducing RPNs for region proposal generation. As a result, object detection was accomplished in a more timely and accurate manner, and it was suitable for use in CBIR-related endeavors. Gong, Lazebnik, Gordo, and Perronnin [6] proposed an iterative quantization method for learning binary codes from deep features. This method enables efficient and compact picture representations for CBIR, which are essential for the algorithm. In [7], the author presented the idea of employing neural codes to retrieve images. In this approach, deep features are learned to represent images in a binary code space, which enables efficient image retrieval through the use of Hamming distance. In [8], the author proposed Focal Loss, which addresses the issue of extreme class imbalance in object detection tasks, by assigning higher weights to hard examples during training, leading to improved accuracy and efficiency in object detection.

The author in [9] introduced DenseNet, a densely connected convolutional neural network (CNN) architecture that connects each layer to every other layer in a feed-forward manner, reducing the number of parameters and improving the accuracy and efficiency of deep CNNs. Huang, Liu, and Weinberger [10] presented the DenseNet architecture and its advantages in terms of reducing redundancy and improving gradient flow in deep CNNs. The author [11] presents an improved version of atrous convolution, also called dilated convolution, for semantic image segmentation, which enables efficient feature extraction at multiple resolutions and reduces the computational cost of the convolutional operation.

The author in [12] proposed nonlocal neural networks, which capture long-range dependencies in images or feature maps through nonlocal operations, enabling efficient modeling of global contextual information and improving the performance of deep neural networks. In [13], the authors presented interleaved structured sparse convolutional neural networks, which leverage structured sparsity patterns in convolutional filters to reduce the computational cost of CNNs, while maintaining accuracy in image classification tasks. The spatial methods Gray Level Run Length Matrix (GLRLM), GLCM, and Gabor wavelet algorithms were investigated by Ergen et al. [14]. We conducted an in-depth analysis of these methods, examining both their benefits and their drawbacks. Ban et al. [15] presented the methods necessary to obtain the superior threshold in order for the fuzzy partition to be achieved. Following this, the fuzzy c-means algorithm is applied in order to carry out the image classification process. The authors proceeded to compute the degree of subjugation exhibited by a single image within each category. The mathematical underpinnings of the technique are laid out in an understandable manner [16]. Malliga et al. introduced a system called content-based medical image retrieval (CBMIR), which was based on the modified fuzzy c means clustering algorithm. In the beginning of this process, the Haralick and Texture spectrum features are taken from a database of medical images. The FCM clustering technique is used to group the characteristics that were collected from the training photos that were found in the CSSE (2022, vol. 43, no. 2) 685 database, as well as the evaluation and confirmation of the quality of this work’s performance. The researchers Fu et al. [17] investigated the actual deep features that were created by a convolutional neural network (CNN) for the CBIR system. They also trained a hyperplane that can differentiate between related and distinct picture pairs by utilizing a linear support vector machine (SVM). The support vector machine (SVM) was used to generate output results by having the pair features provided by a pair of images, including the query image and every test image present in the image dataset, fed into it.

This chapter makes several significant contributions. First, it highlighted the effectiveness of deep-learning-based content-based image retrieval (CBIR) approaches, particularly leveraging 3D convolutional neural networks (3DCNN), as a means to improve the efficiency and accuracy of image retrieval in healthcare settings. This underscores the importance of advanced technologies in enhancing the diagnostic and research capabilities of medical professionals.

Second, the chapter introduces the integration of 3DCNN with blockchain technology, creating a secure and efficient ecosystem for the management of medical images and videos. By securely storing compact descriptors of these images on a blockchain, it ensures data integrity, transparency, and access control. Moreover, it automates the management of ownership and copyrights using smart contracts, a critical aspect in the sensitive realm of healthcare data. The chapter’s applicability to the healthcare sector is particularly noteworthy, as it promises to revolutionize the way medical data is stored and retrieved. This fusion provides a robust and tamper-proof solution for image and video management, enhancing the quality of diagnosis, treatment, and research in the health-care field.

2.3 PROPOSED METHODOLOGY

Data preparation, model training, feature extraction, feature fusion, similarity assessment, and retrieval are the important elements in the technique that we have developed for effective content-based image retrieval (CBIR) with deep learning. Figure 2.1 provides a visual representation of our overall research approach.

FIGURE 2.1 Proposed workflow.

2.3.1 DATASET COLLECTION

The research utilized a publicly available SARS-CoV-2 CT scan dataset comprising 1252 CT scans from patients positively diagnosed with SARS-CoV-2 (COVID-19) infection and 1230 CT scans from noninfected patients, totaling 2482 CT scans. This diverse dataset, with both positive and negative cases, forms the foundation of our research into content-based image retrieval using 3DCNN and blockchain in healthcare. Figure 2.2 shows the SARS-COV-2 CT-scan dataset.

FIGURE 2.2 SARS-COV-2 CT-Scan Dataset: (a) COVID and (b) non-COVID.

Table 2.1. shows the collection of COVID and non-COVID images from the SARS-COV-2 CT scan dataset.

TABLE 2.1 Dataset Collection

Dataset Name | Number of COVID Images | Number of Non-COVID Images | Total Number of Images
SARS-COV-2CT-Scan Dataset | 1252 | 1230 | 2482

2.3.2 DATA PREPROCESSING

Before applying our methodology, the dataset underwent rigorous preprocessing. Raw CT scan images were subjected to resizing, normalization, and noise reduction to ensure consistency and enhance the quality of the images. Figure 2.3 shows the process of preprocessing of images.

FIGURE 2.3 Process of preprocessing.

Preprocessing was conducted with the following equations:

I p r o c e s s e d = P r e p r o c e I r a w

(2.1)

where Iraw represents individual CT scan images, and Iprocessed represents the preprocessed images.

Resizing: Resizing is an essential step in data preprocessing, which involves altering the dimensions of the CT scan images shown in Figure 2.4. This is usually done to ensure uniformity in size, which is crucial for consistent processing and analysis. A common approach is to apply a resizing operation that scales the image to a target width and height. This step ensures that all images are in the same format, allowing for accurate feature extraction. It’s achieved by scaling the images to a target width (W) and height (H). The resizing equation is:

Iresized=ScaIraw,W,H

(2.2)

FIGURE 2.4 Original image vs. resized image.

Normalization: Normalization is a process to adjust the pixel values within CT scan images to a standardized range, as shown in Figure 2.5. This is vital for ensuring that the neural network can effectively learn from the data. One commonly used method is min-max normalization, where pixel values are scaled to fall within a specified range, typically [0, 1] or [−1, 1].

FIGURE 2.5 Normalized resized image.

This standardization improves the consistency of pixel values across all images. This is achieved with the following equation:

I n o r m a l i z e d = I r e s i z e d − min I r e s i z e d max I r e s i z e d − I r e s i z e d

(2.3)

Noise Reduction: Noise reduction techniques are employed to enhance the quality of CT scan images by mitigating unwanted artifacts and variations. While several noise reduction methods are available, one common approach involves applying a Gaussian filter. Gaussian noise reduction helps to smooth the images by reducing high-frequency noise, as shown in Figure 2.6. This operation aims to improve the interpretability and quality of the images, making them more suitable for feature extraction and subsequent analysis. One common method involves applying a Gaussian filter with a specified standard deviation (σ). The equation for Gaussian noise reduction is:

Idenoised=Apply Gaussian FilterInormalized, σ

(2.4)

FIGURE 2.6 Noise-reduced image.

2.3.3 FEATURE EXTRACTION

Feature extraction using 3D convolutional neural networks (3DCNN) is a pivotal step in the methodology. 3DCNNs are deep learning models designed to analyze 3D data, making them particularly suitable for processing CT scans, which inherently have three-dimensional aspects. The key objective is to automatically learn and extract essential features from the preprocessed images, without requiring manual feature engineering.

F = 3 D C N N I n o r m a l i z e d

(2.5)

where F represents the extracted features, and Inormalized denotes the preprocessed and normalized CT scan image.

The 3DCNN model leverages convolutional layers, pooling layers, and fully connected layers to learn intricate and abstract features from the input image. These features capture critical spatial and temporal information, which are essential for identifying patterns, structures, and anomalies within the CT scans, enabling subsequent steps like content-based image retrieval and disease classification.

2.3.4 DESCRIPTOR GENERATION

After extracting features using 3DCNN, the next step is to create compact descriptors from these features. Descriptors are representations that capture the most salient information while reducing the dimensionality of the data. This step is crucial to ensure efficient and effective content-based image retrieval.

D = R e d u c e _ D i m e n s i o n a l i t y F

(2.6)

where D represents the generated descriptors, and F signifies the features extracted using 3DCNN.

The reduction of dimensionality is achieved through various techniques, such as principal component analysis (PCA) or autoencoders. These methods condense the feature-rich data into a more manageable form, preserving the most informative elements. The resulting descriptors serve as the basis for subsequent steps in content-based image retrieval, where images are compared and matched based on the similarity of their descriptors.

2.3.5 BLOCKCHAIN INTEGRATION

Blockchain integration is a pivotal step in the methodology, designed to ensure the security and integrity of medical image data. This technology serves as a decentralized ledger, recording and safeguarding descriptors derived from CT scan images. It plays a vital role in addressing issues related to data tampering and access control, making it a valuable addition to the healthcare domain.

The integration includes essential operations like data hashing, where descriptors are securely converted into unique cryptographic representations. These hashed values are then stored on the blockchain. The utilization of smart contracts automates the management of data access and ownership, ensuring ethical and secure handling of medical image data. While there isn’t a single equation to represent blockchain integration, it involves a sequence of blockchain transactions and smart contract operations that collectively secure and manage the CT scan descriptors, providing a tamper-proof and transparent environment for content-based image retrieval.

D a t a   H a s h i n g :   H = H a s h D

(2.7)

where H represents the hashed data before storing it on the blockchain.

B l o c k c h a i n   S t o r a g e : B l o c k c h a i n .   A d d H  

(2.8)

Here the data is added to the blockchain ledger.

2.3.6 QUERY AND RETRIEVAL

Query and retrieval represent the phase where healthcare professionals, researchers, or users interact with the system to find relevant medical images. In this context, the CT scan descriptors or hashed values, previously stored on the blockchain, play a central role. Users can submit queries, often in the form of descriptors or other search criteria, to identify and retrieve CT scan images that match their needs.

M = M a t c h _ Q u e H q u e r y ,   B l o c k c h a i n

(2.9)

M represents the matching result, indicating the degree of similarity between the query and stored descriptors.

Hquery is the descriptor or hashed value of the query.

Blockchain refers to the blockchain ledger containing the stored descriptors. The system processes the query and retrieves relevant CT scan images by comparing the hashed query with the stored descriptors on the blockchain.

2.4 EXPERIMENTAL RESULTS AND DISCUSSION

Medical imaging has seen tremendous advancements, thanks to innovative technologies like 3D convolutional neural networks (3DCNN). These networks represent a significant leap forward in the analysis of volumetric medical data, enabling more accurate and robust diagnostics. In this comprehensive overview, we delve into the world of 3DCNNs, exploring their architecture, applications, and the transformative impact they’ve had on healthcare.

2.4.1 CONVOLUTIONAL LAYERS: THE BACKBONE OF 3DCNN

At the heart of every 3DCNN lies its convolutional layers, the foundation upon which the network learns to identify and extract spatial features. These layers are akin to filters that slide over the input volumetric data, computing dot products at each position. The outcome is a feature map that highlights the presence of certain features within the data. Understanding the mechanics of convolution is essential to grasp the architectural intricacies of 3DCNNs.

The convolution operation is mathematically defined as:

F e a t u r e   M a p = I n p u t   D a t a ⊗ F i l t e r

(2.10)

Here, Feature Map represents the output, capturing the presence of specific features. Input Data is the original volumetric data, and Filter signifies the learned kernel or filter used for feature detection.

2.4.2 ACTIVATION FUNCTIONS: INJECTING NONLINEARITY

The feature maps generated by convolutional layers are often passed through activation functions, an integral element of 3DCNN architecture. Activation functions introduce nonlinearity into the network, enabling it to capture complex relationships within the data. Without these functions, the network would essentially behave as a series of linear transformations, limiting its capacity to model intricate patterns. Some commonly used activation functions in 3DCNNs include ReLU (Rectified Linear Unit), Sigmoid, and Tanh.

R e x = m a x 0 , x

(2.11)

The ReLU function replaces any negative values with zero, effectively introducing nonlinearity by allowing only positive values to pass through. This property enables the network to learn and represent complex features more effectively.

2.4.3 3DCNN ARCHITECTURAL COMPONENTS

3DCNN architecture is built on a series of layers, each with specific roles and responsibilities. It’s essential to understand these components to appreciate the overall design of the network.

The input layer is where volumetric data, such as CT scans or 3D MRI images, are fed into the network. The data typically consists of multiple slices in the form of a 3D grid. Convolutional layers come next, with multiple filters that slide over the input data to detect various features. These layers are stacked to capture increasingly complex patterns. After convolution, feature maps are passed through activation functions to introduce nonlinearity, making the network capable of modeling intricate relationships. Pooling layers reduce the spatial dimensions of the feature maps, down-sampling the data. This aids in decreasing the computational complexity and preventing overfitting.

P o o l e d   D a t a = m P o o l i n g   R e g i o n

(2.12)

In the case of max pooling, the operation selects the maximum value within a pooling region, effectively reducing the size of the data.

2.4.4 CONCATENATION: A KEY ARCHITECTURAL ELEMENT

Concatenation is a vital architectural element in 3DCNNs, especially in more complex designs. It involves combining or stacking feature maps from multiple convolutional or pooling layers. Concatenation can occur along the depth axis, adding depth to the feature maps. This depth enhancement enables the network to capture a richer set of features, improving its performance.

C o n c a t e n a t e d   F e a t u r e s = C o n c a t e n a t e F e a t u r e   M a p 1 ,   F e a t u r e   M a p 2 , … ,   F e a t u r e   M a p n

(2.13)

In this equation, Concatenated Features represent the resulting feature maps after the concatenation operation. Feature Map_1, Feature Map_2, Feature Map_n are individual feature maps that are combined to create more informative and enriched representations.

2.4.5 FULLY CONNECTED LAYERS

Fully connected layers interpret high-level features extracted by the earlier layers and prepare them for classification or regression tasks.

O u t p u t = W ⋅ I n p u t + b

(2.14)

Concatenation is particularly valuable when dealing with complex 3D datasets, as it allows the network to fuse multiscale features and capture spatial information at various levels. This multiscale approach enhances the network’s ability to identify patterns, anomalies, and structures within the volumetric data, making it indispensable in medical image analysis.

2.4.6 B LOCKCHAIN INTEGRATION IN 3D CONVOLUTIONAL NEURAL NETWORKS ENSURING DATA SECURITY WITH HASHING

A fundamental aspect of blockchain integration is the use of cryptographic hashing to ensure data security. Each descriptor extracted from a medical image is hashed using a secure hash function, such as SHA-256. The equation for cryptographic hashing is:

H a s h = S H A − 256 D e s c r i p t o r

(2.15)

Here Hash represents the resulting cryptographic hash of the descriptor, computed using the SHA-256 algorithm.

2.4.7 BLOCKCHAIN TRANSACTION RECORDING

Blockchain’s primary function is to record data transactions in a tamper-proof manner. In the context of 3DCNN, each hashed descriptor, along with metadata like timestamps, is recorded as a blockchain transaction. The equation for recording a transaction can be simplified as:

T r a n s a c t i o n = R e c o H a s h ,   M e t a d a t a ,   T i m e s t a m p

(2.16)

This equation represents the core operation of recording data on the blockchain.

2.4.8 SMART CONTRACTS FOR ACCESS CONTROL

Smart contracts play a pivotal role in controlling data access. These self-executing contracts are defined with access control rules. The equation for smart contract execution can be expressed as:

A c c e s s = S x e c u S m a r t   C o n t r a c t ,   U s e r   P e r m i s s i o n s

(2.17)

Here Access signifies the result of the smart contract execution, determining whether users are granted access based on their permissions.

2.4.9 DATA RETRIEVAL WITH BLOCKCHAIN QUERIES

Authorized users can query the blockchain to retrieve specific medical image data based on descriptors, unique identifiers, or patient information. The query operation can be formulated as:

Q u e r y = S e a r c h B l o c k c h a i n ,   D e s c r i p t o r ,   U s e r   P e r m i s s i o n s

(2.18)

In this equation, Query represents the query result, allowing users to retrieve data that matches their criteria while respecting their permissions.

We utilized the cosine similarity metric to determine the degree of similarity between two feature vectors. This metric measures the cosine of the angle that separates the two feature vectors and has a range that goes from −1 to 1, with 1 indicating that the feature vectors are the same and −1 indicating that they are completely different.

Table 2.2 provides an overview of the performance evaluation of the Proposed Model and other models in the context of medical image analysis, specifically for disease classification. The metrics used for evaluation include Accuracy, Sensitivity (also known as True Positive Rate or Recall), Specificity, Precision, and the F₁ Score. Accuracy measures the overall correctness of the model’s predictions, and in this case, the Proposed Model achieves an impressive accuracy of 99.7%, indicating that it accurately classifies nearly 99.7% of the cases.

TABLE 2.2 Proposed and Evaluated Models Exhibit Comparable Performance

Model | Accuracy (%) | Sensitivity (%) | Specificity (%) | Precision (%) | F, Score (%)
Proposed Model | 99.7 | 99.6 | 99.2 | 99.3 | 99.4

Sensitivity quantifies the model’s ability to correctly identify positive cases, with the Proposed Model achieving a high sensitivity of 99.6%, signifying its accuracy in identifying 99.6% of actual positive cases. Specificity gauges the model’s capability to correctly identify negative cases, with a notable 99.2% for the Proposed Model, showcasing its accuracy in identifying 99.2% of actual negative cases.

Precision evaluates the accuracy of positive predictions, indicating that 99.3% of the positive predictions made by the Proposed Model are accurate. The F₁ Score, which harmonizes precision and sensitivity, demonstrates a well balanced performance, with the Proposed Model achieving a score of 99.4%. These metrics collectively emphasize the model’s robustness and effectiveness in medical image analysis, particularly for disease identification. Figures 2.7(a) and 2.7(b) show the training and testing loss and accuracy of 3DCNN in 100 epochs.

FIGURE 2.7 3DCNN: (a) training and testing loss and (b) training and testing accuracy.

2.5 CHALLENGES

Deep learning that is effective for content-based picture retrieval presents a number of obstacles.

Scalability: This is a problem that arises when picture databases continue to expand in size since it makes it harder to retrieve photos effectively. To function effectively on large-scale picture datasets, deep learning models that contain a substantial number of parameters may demand a significant amount of the computational resources available, such as memory and processing power.

Complexity in Computational Work: Deep learning models, particularly those with intricate architectures, can provide challenges in terms of their computational requirements during both the training and inference stages. In applications that need low-latency and high-throughput processing, such as real-time or near-real-time picture retrieval, this can limit the efficiency of the systems in question.

Model Interpretability: Since deep learning models do not have any kind of interpretability, they are frequently referred to as black box models. This is because it is impossible to understand and interpret the decision-making process that they use. When it comes to content-based picture retrieval, this might be a barrier for users, as they may need to understand and interpret the results for their image search queries.

Images used in content-based image retrieval tasks can display significant variety in terms of scale, orientation, illumination, viewpoint, and other aspects. This variability can be caused by a number of different factors. It can be difficult to successfully handle such variability in deep learning models, and doing so may involve the application of specialized approaches such as data augmentation, normalization, and regularization in order to provide retrieval results that are reliable and accurate.

Feature Representation: In the process of content-based image retrieval, this is one of the most important steps and involves the extraction of meaningful and distinguishable characteristics from images. For effective feature learning, deep learning models may require vast volumes of labeled data. It might also be difficult to construct appropriate architectures and loss functions in order to learn useful features from photos.

Data Privacy and Security: The utilization of sensitive data, such as personal photographs, medical images, or other private data, may be required when using content-based image retrieval systems. In image retrieval systems that are based on deep learning, it might be difficult to ensure the data’s privacy and security, including dealing with issues such as data breaches, data misuse, and ethical considerations.

Domain-Specific Obstacles: Depending on the application area, effective deep learning for content-based picture retrieval may be met with domain-specific obstacles. For instance, medical image retrieval may necessitate the management of concerns such as restricted data availability, class imbalance, and domain-specific image features. On the other hand, multimedia retrieval may want the handling of obstacles related to multimodal data, cross-modal retrieval, and large-scale multimedia databases.

In order to find solutions to these problems and make deep learning more effective for content-based picture retrieval, one must carefully evaluate a number of different elements. These factors include model design, optimization approaches, data pretreatment, interpretability, and domain-specific concerns. In order to address these problems and enable more efficient and effective content-based picture retrieval systems, further research and developments in deep learning algorithms, hardware technologies, and data management approaches are required.

Data Privacy and Security: Ensuring the privacy and security of sensitive medical data is a paramount challenge. Healthcare data often contains confidential patient information, and maintaining its privacy while using blockchain is a complex task.

Blockchain Scalability: Handling the large volume of medical images, descriptors, and transactions generated by 3DCNN can pose scalability challenges for the blockchain network. Efficient data storage and management are essential.

Data Retrieval Efficiency: Ensuring efficient and fast retrieval of medical image data from the blockchain is crucial for healthcare applications. Low-latency data access is a challenge, especially in real-time clinical scenarios.

Blockchain Adoption: Encouraging healthcare institutions and professionals to adopt blockchain technology can be met with resistance and skepticism due to the learning curve, concerns about the technology’s maturity, and potential disruption to existing workflows.

2.6 LIMITATIONS

Effective deep learning for content-based image retrieval comes with a few caveats; for example:

Deep learning models often require substantial volumes of labeled data in order to undergo effective training; however, this data is not always readily available. In certain fields, such as specialized medical imaging or the recovery of rare objects, annotated data may be difficult to come by or prohibitively expensive to acquire. This hinders the effectiveness of image retrieval systems that are based on deep learning.

Overfitting and Generalization: Deep learning models are prone to overfitting, particularly when they are trained on a little amount of data. Generalization is also a risk. Overfitting a model can lead to poor generalization performance, in which the model may not perform well on pictures for which it has not been trained, which can result in decreased retrieval accuracy and efficiency.

Computational Resource Requirements: Deep learning models with complex architectures, such as deep convolutional neural networks (CNNs) or recurrent neural networks (RNNs), may require significant computational resources, such as high-performance GPUs, memory, and processing power.

Explainability and Interpretability: Deep learning models are frequently referred to as black-box models since they lack both interpretability and explainability. This can make it difficult to understand and interpret the decisions made by the model, which can lead to limits in explaining the retrieval results to users or discovering and fixing potential biases or errors. Additionally, this can make it difficult to explain the results to users.

Sensitivity to Hyperparameters: Deep learning models frequently feature several hyperparameters, such as learning rate, batch size, and network architecture, that need to be set for optimal performance. To achieve this, it is necessary to pay attention to the sensitivity of these hyperparameters. However, obtaining the ideal collection of hyperparameters can be a time-consuming and computationally expensive process, and using settings that are inappropriate for the hyperparameters might result in decreased retrieval performance.

Conceptual Comprehension of Features: Although deep learning models automatically learn features from data, there is a possibility that the models’ conceptual comprehension of the features they have learnt is limited. As a result, interpreting and analyzing the relevance and quality of the learned features for content-based image retrieval tasks can be a difficult undertaking.

There is a lack of uniformity in terms of the model architectures, training methods, and assessment metrics for content-based picture retrieval in the field of deep learning, which is quickly growing. This might make it difficult to compare and repeat results across many research or datasets, which in turn can lead to limitations in the findings’ reliability and generalizability.

Ethical and Legal Considerations: There is a possibility that deep-learning-based image retrieval systems will give rise to ethical and legal considerations. These concerns may include the possibility of bias in the results of the retrieval, issues with privacy, and ownership of the data. Deep learning-based image retrieval systems present a difficulty that needs to be properly addressed in order to avoid potential dangers and limitations. This challenge entails ensuring justice, accountability, and openness in the systems.

Computational Intensity: 3DCNN, especially in medical imaging, can be computationally intensive, requiring substantial processing power and memory. This may limit its practicality for healthcare providers with limited resources.

Scalability: Managing a large volume of medical images, descriptors, and transactions on the blockchain can lead to scalability issues. As the system grows, it may become challenging to maintain performance and efficiency.

Data Immutability: While blockchain’s immutability is a benefit, it can be a limitation in cases of data errors or incorrect entries. Once data is recorded on the blockchain, it is challenging to rectify mistakes.

It is essential to have an awareness of these restrictions and to take them into account throughout the development, deployment, and assessment of effective deep-learning-based content-based picture retrieval systems. In order to overcome these restrictions and enable content-based picture retrieval systems that are more resilient and trustworthy, further research and developments in deep learning algorithms, data availability, interpretability, and ethical considerations are required.

2.7 CONCLUSION

4.1 INTRODUCTION

Data may be stored and tracked in a trustworthy and open way with the help of a technology called blockchain. Blockchain is a decentralised digital ledger [1]. It is best recognised as the technology that underpins cryptocurrencies like Bitcoin and Ethereum; nevertheless, it has the potential to be used in a wide variety of other contexts in addition to the financial sector.

At its most fundamental level, a blockchain can be understood as a decentralised, digital ledger of all the transactions occurring across a computer network. Once a block has been added to the chain, it cannot be altered or removed without disrupting the entire chain. Each block in the chain holds a record of several transactions. Because of this, every node in the network has a copy of the same record, resulting in a safe and transparent record of all transactions on the network.

One of the primary benefits of blockchain technology is its potential to do away with the requirement for intermediaries in financial transactions. This has the potential to both lower transaction costs and improve operational efficacy. For instance, blockchain technology can be used in the supply chain industry to trace things from the manufacturer to the end user. This provides a safe and transparent record of all transactions, reducing the likelihood of fraud or other errors.

Identity management is a sector where blockchain technology may also be used. Individuals can have more control over their data and who has access to it while ensuring security and privacy by developing a decentralised identification system.

In general, blockchain technology can fundamentally alter how we store and move data, and its uses go far beyond just cryptocurrencies. We may anticipate additional creative uses in various industries as the technology develops and improves.

Blockchain is a new supply chain network and online infrastructure based on distributed applications. Blockchain maintains information sharing through a dispersed network of computers (nodes). Each node provides data security and accuracy by keeping all transaction ledgers. A miner creating a new block is the first to use the hash function to construct a digital signature that meets the rules, validates all transactions, and solves the mathematical issue. Since the new block is broadcast to the blockchain network, all nodes can preserve the same accurate record [2].

4.2 APPLICATIONS OF BLOCKCHAIN TECHNOLOGY

Money Transfer and Payment Processing: The use of blockchain technology as a mechanism to speed up the movement of cash from one party to another is one of the applications that has the potential to be the most optimal and logical application of the technology. Most transactions via blockchain can be finalised in seconds, but banks can take up to 24 hours or even seven days to complete the same task (Figure 4.1).

FIGURE 4.1 Applications of blockchain technology [1].

Supply Chain Monitoring: Supply chain monitoring is simple using block-chain technology. By eliminating paper trials, companies may quickly identify supply chain bottlenecks and detect problems in real time. Blockchain allows enterprises and consumers to monitor product quality from origin to retailer.

Retail Programmes Based on Loyalty Rewards: Blockchain helps transform retail by becoming the loyalty incentive standard. A token-based system that rewards and stores consumers on a blockchain would incentivise shoppers to return to a business or chain. It would eliminate paper- and card-based loyalty rewards programme fraud and waste [3].

Digital IDs: Over 1 billion individuals worldwide struggle with identity. Microsoft wants to change that. Digital IDs, used by millions, are being designed for its Authenticator software to help users manage their digital identities. This would help impoverished people receive banking services or start businesses.

Sharing of Data: Cryptocurrency IOTA’s November Data Marketplace beta explained how blockchain could be used to share or sell unneeded data. Most company data remains unused; therefore, blockchain might be stored and moved to improve several industries.

Protection of Royalty and Copyright: With increased internet access, music and other copyright and royalty restrictions have become claggy. Blockchain can be used to strengthen digital content copyrights to ensure inventor get their due.

Digital Voting: Blockchain allows digital voting and is transparent enough for regulators to see network changes. It combines the simplicity of digital voting with blockchain’s immutability to make votes count.

Transfer of Real Estate, Land, and Auto Title: Since paper trails are confusing, Blockchain aims to eliminate them. People must transfer or get titles when buying or selling land, houses, or cars. Blockchain stores titles on its network, making this transfer transparent and revealing legal ownership.

Food Safety: The ability to track food from its origin to the consumer’s plate is yet another exciting application of blockchain technology. Because the data stored in a blockchain cannot be altered, it is possible to trace food goods’ journey from their factory to the store where they are sold.

Unchangeable Data Backup: Blockchain is perfect for data backup. Cloud storage solutions are designed to protect data, but hackers and technical issues can compromise them. Blockchain backups for cloud data centres or any data could solve this problem [4].

4.3 IMPLICATIONS AND CHALLENGES OF THE DATA DELUGE

The rapid and exponential expansion of data stored in blockchain databases is called the data deluge in blockchain technology [5]. Data collection is a tribute to the growing use and usage of blockchain technology; nevertheless, it also offers several consequences and difficulties that must be addressed. These must be solved before further progress can be made. Here are some essential factors to take into account.

4.3.1 STORAGE COSTS

The costs associated with storing and managing the ever-increasing amount of block-chain data are enormous. As the volume of data continues to increase, it’s possible that traditional storage options could become unaffordable. Blockchain networks need to discover storage solutions that are both cost-effective and scalable to support the growing volume of data as more players join the network and more transactions take place.

4.3.2 NETWORK BANDWIDTH AND LATENCY

Blockchain data deluge might increase network congestion and delay. With more data being carried and stored, network capacity can restrict blockchain network performance. Fast and efficient data transfer is essential for transaction execution and verification.

4.3.3 DATA PRIVACY AND SECURITY

The massive amount of data in blockchain databases poses privacy and security concerns. More sensitive data on the blockchain increases the danger of breaches or unauthorised access. Blockchain data privacy and security are becoming essential to sustaining trust in the system.

4.3.4 REGULATORY COMPLIANCE

Blockchain data inundation complicates regulatory compliance. Blockchain networks must comply with data protection and privacy laws like the GDPR while maintaining data immutability and openness (Figure 4.2). Balancing regulatory obligations with blockchain technology’s core principles is difficult [6].

FIGURE 4.2 Challenges of data deluge [5].

4.4 FEATURES OF BLOCKCHAIN TECHNOLOGY

Blockchain stores data publicly and chronologically in blocks. To protect user privacy and data integrity, data is encrypted using encryption. Decentralised information storage and management means no single authority makes decisions. Most network decisions are made by consensus of all participating nodes worldwide.

4.4.1 INCREASED CAPACITY

This is Blockchain’s first and crucial feature. Blockchain technology boosts network capacity, which is astonishing because several computers operate together, which makes them more potent than centralised devices.

This improved capacity is shown by Stanford University’s supercomputer project that replicates protein folding for medical research.

4.4.2 BETTER SECURITY

Blockchain technology is more secure than its peers because it has no single point of failure. Blockchain functions on a well-distributed network of nodes. Thus, data is constantly circulated via numerous nodes, ensuring data integrity even if one node is hacked or broken.

4.4.3 IMMUTABILITY

Immutable ledgers are a core value of Blockchain. Centralised databases are vulnerable to hackers and fraud since they depend on third parties for security.

Blockchain ledgers like Bitcoin are always forwarding. System nodes have copies of the digital ledger. Every node must verify a transaction before adding it. It goes into the ledger if the majority agrees [7]. This increases transparency and prevents corruption.

Transaction blocks added to the ledger are unchangeable. Therefore, network users cannot change, delete, or update it.

4.4.4 FASTER SETTLEMENT

Traditional banking systems could be faster because of settlement time, which might take days. This is one of the key reasons why banks require new systems. Blockchain can fix this problem by transferring money quickly. This saves institutions time and money and makes it more convenient for consumers.

4.4.5 DECENTRALISED SYSTEM

Decentralised technology lets you store assets in a network without a single administrator. Through a key attached to the account, the owner can transfer assets to anybody they wish. Blockchain technology can decentralise the web, which could revolutionise the internet.

4.4.6 CONSENSUS

The consensus algorithm makes blockchain technologies effective. Every blockchain has this trait, which defines it. The network’s nodes make decisions through consensus. Nodes can reach an agreement rapidly here.

When millions of nodes validate a transaction, a consensus is essential for system stability. Consider it a voting system where the majority wins, and the minority must support it [8]. Truthfully, unanimity makes the system untrustworthy. Nodes may not trust one another but can trust the underlying algorithms. So, every network decision is a gain for the blockchain.

4.4.7 DISTRIBUTED LEDGER

Public ledgers show transactions and participants. Unlike private or federated ledgers linked to a blockchain system, such ledgers lack security and authority. Because all network users maintain the ledger, this distributes processing power across machines for better results.

Any authorised user can view the distributed ledger, making the process visible and dependable.

4.4.8 IT CANNOT BE CORRUPTED

The digital ledger is replicated on every node that makes up the network. Before adding a transaction, each record must verify that it is valid. It will be if most people agree that it should be included in the ledger. This helps to foster transparency and makes it resistant to corruption.

4.4.9 MINTING

Blockchain can solve several manipulation problems. Banks and international tech titans like Google and Meta inspire trust and responsibility in the West [9].

Blockchain prospects are more significant in countries where mining is the primary method but has yet to be levelled. However, numerous additional approaches have been proposed, such as proof-of-work, which can show that a person does a lot of computation work.

4.5 ADVANTAGES OF BLOCKCHAIN OVER NON-BLOCKCHAIN DATABASE

Immutability: Blockchain data cannot be deleted or replaced. Thus block-chain precludes network data from being tampered with. Traditional data is not immutable. Conventional databases use CRUD (create, read, update, and delete) at the primary level to ensure application operation and allow data erasure and replacement. Third-party hackers or unscrupulous administrators can manipulate such data.

Transparency: Any network member can verify blockchain data because it’s decentralised. The people may trust the network. Traditional databases are centralised and opaque. User verification is limited, and the management ensures the data is public. Individuals cannot check the data.

Censorship: Since blockchain is decentralised, it cannot be censored. Thus no authority—including governments—can disrupt the network. In traditional databases, central authorities control network activity and can censor. Banks have the authority to suspend user accounts [10].

Traceability: Blockchain technology generates an unalterable audit trail, which makes it simple to track changes made to the network. The conventional database needs to be more transparent and immutable; as a result, there is no assurance of a permanent audit trail being kept.

4.6 DECENTRALISED DATA STORAGE VS. TRADITIONAL CENTRALISED DATABASES

The advantage of decentralised storage is that it can compare centralised and decentralised systems. The first benefit of decentralised storage is security. Decentralisation in storage systems distributes user files among network nodes. The network has no single point of failure because its data is spread across nodes.

Data availability is another benefit of decentralised storage. In centralised systems, losing a server might cause downtime. Decentralised storage provides data access through other nodes, ensuring availability. Every peer-to-peer network node in decentralised storage would have an updated copy of the distributed database.

The answers to “ ‘What is centralised storage?” and the basics of decentralised storage show the differences. Learning about the head-to-head contrasts between the two primary data storage methods is also significant [11].

Figure 4.3 shows some critical differences between centralised and decentralised storage.

FIGURE 4.3 Centralised vs. decentralised storage [8].

4.6.1 COSTS OF STORAGE

Initial comparisons between decentralised and centralised storage focus on system costs. Centralised data storage requires personnel compensation, administrative costs, data centre leases, legal and accounting fees, and overhead. Additionally, data migration between two centralised storage platforms is expensive. On the other hand, decentralised data storage saves money—no data server upkeep or rent, for example. Interoperability also allows low-cost data migration between decentralised storage solutions.

4.6.2 DATA TRANSFER SPEED

Data transport speed is another critical factor when comparing centralised and decentralised data storage. Centralised data storage typically uses a cloud server within the user’s distance. Additionally, many intermediaries must approve the user’s data request.

Data transmission speeds drop considerably. The answer to “What is the difference between centralised and decentralised storage?” would show how decentralisation eliminates intermediaries. You can pass data through a few intermediaries.

4.6.3 SECURITY

Centralised data storage is the most noticeable aspect of centralisation. Centralised servers are also in remote areas where catastrophe response is delayed. Therefore, centralised data storage systems face physical and cybersecurity dangers. Cryptography and novel methods like zero-knowledge proofs can improve security and user privacy in decentralised storage [12].

Server owners and storage service companies may manipulate data in centralised systems. All network members’ copies mirror any ledger change in decentralised storage. Thus decentralised storage makes user data security and privacy impossible to compromise.

4.7 CRYPTOGRAPHIC TECHNIQUES IN BLOCKCHAIN FOR DATA SECURITY

Cryptography protects data. Cryptography secures blockchain transactions between nodes. The two essential elements of blockchain are encryption and hashing. Cryptography encrypts P2P messages, whereas hashing secures block information and links blockchain blocks.

Cryptography prioritises participant, transaction, and double spending security. It secures blockchain transactions. It restricts transaction data access, reading, and processing to the intended recipients [13].

Blockchain data security relies on cryptography. Blockchain uses the following cryptographic methods to secure data.

4.7.1 HASH FUNCTIONS

Purpose: Hash functions convert data of arbitrary size into a fixed-size string of characters, typically a hexadecimal number.

Use Case: Hashing is commonly used to create unique identifiers for blocks and transactions. Any change in the input data will result in a completely different hash value, making it easy to detect tampering with the data.

4.7.2 DIGITAL SIGNATURES

Purpose: Digital signatures provide authentication and integrity for transactions and messages in a blockchain.

Use Case: When users initiate a transaction, they sign it with their private key. Other users can verify the transaction’s authenticity using the sender’s public key.

4.7.3 PUBLIC AND PRIVATE KEY CRYPTOGRAPHY

Purpose: Public and private key pairs are used for secure key exchange, encryption, and decryption.

Use Case: In Blockchain, public keys generate addresses, while private keys are kept secret and used for signing transactions. Public key cryptography ensures secure communication between participants.

4.7.4 SYMMETRIC AND ASYMMETRIC ENCRYPTION

Purpose: Encryption techniques are used to protect the confidentiality of data.

Use Case: In Blockchain, symmetric encryption is sometimes used to encrypt data before storing it off-chain. Asymmetric encryption, involving public and private keys, is used for secure communication and data sharing between participants.

4.7.5 MERKLE TREES

Purpose: Merkle trees are used to efficiently prove the integrity of a specific piece of data within a larger dataset.

Use Case: In a blockchain, Merkle trees help validate the contents of a block by allowing nodes to prove that a particular transaction is included in the block without revealing the entire block’s contents.

4.7.6 ZERO-KNOWLEDGE PROOFS

Purpose: Zero-knowledge proofs allow one party (the prover) to prove to another party (the verifier) that they know a specific piece of information without revealing it.

Use Case: Zero-knowledge proofs enhance privacy in Blockchain by allowing transactions to be validated without revealing transaction details [14].

4.7.7 RING SIGNATURES

Purpose: Ring signatures are digital signatures that can hide the actual signer within a group of possible signers.

Use Case: Ring signatures are used in privacy-focused blockchains to obfuscate the sender’s identity in a transaction while still proving the transaction’s authenticity.

4.7.8 MULTI-SIGNATURE WALLETS

Purpose: Multi-signature wallets require multiple private keys to authorise a transaction, adding an extra layer of security.

Use Case: In blockchain applications where multiple parties need to autho-rise a transaction, such as corporate accounts or joint ventures, multi-signature wallets are employed to prevent unauthorised access [15].

4.8 ROLE OF PUBLIC AND PRIVATE KEYS IN ACCESS CONTROL

Public and private keys are fundamental to access control within various cryptographic systems, including blockchain technology. Here’s an explanation of their roles in access control.

4.8.1 AUTHENTICATION

Public Key: The public key is made freely available to anyone and serves as the user’s identity or address within the system. Others use it to verify the authenticity of data signed with the corresponding private key.

Private Key: The private key is known only to the user and is used to prove ownership of the associated public key. It is a cryptographic “key” to access users’ resources or perform actions on their behalf.

4.8.2 DIGITAL SIGNATURES

Public Key: Public keys are used by others to verify digital signatures created by the corresponding private key. When users sign a message or transaction with their private keys, anyone with access to their public key can verify that the data hasn’t been tampered with and was indeed signed by the private key owner.

Private Key: The private key is used to create digital signatures. Only private key owners can produce a valid signature for their data. This ensures the integrity and authenticity of the data.

4.8.3 SECURE COMMUNICATION

Public Key: Public keys can encrypt data that only the corresponding private key can decrypt. This enables secure and private communication between parties. When someone encrypts data with another user’s public key, only the holder of the corresponding private key can decrypt and access the data.

Private Key: The private key is used to decrypt data that has been encrypted with the corresponding public key. It ensures that only the intended recipient can access the information.

4.8.4 ACCESS TO DIGITAL ASSETS

Public Key: Public keys are often used as addresses in blockchain and crypto-currency systems. They represent the ownership of digital assets (e.g., crypto-currencies). Other users can send assets to these addresses to transfer ownership.

Private Key: The private key associated with a cryptocurrency address allows owners to access and manage their digital assets. It serves as the cryptographic proof of ownership and control.

4.8.5 ACCESS CONTROL IN SMART CONTRACTS

Public Key: Public keys can be used in smart contracts to determine who has permission to execute specific actions or access certain resources. Intelligent contracts can validate the authenticity of public keys to grant or restrict access (Figure 4.4).

FIGURE 4.4 Roles of public and private keys [12].

Private Key: The private key associated with a public key used in a smart contract can authorise specific actions. For example, a private key can approve a financial transaction in a decentralised application.

In summary, public keys are used for identification and verification, while private keys are used for access control and authentication. This asymmetric cryptographic pair forms the basis of secure and decentralised access control in blockchain systems and many other digital security applications [16].

4.9 SCALABLE DATA STORAGE SOLUTIONS

Today’s digital age requires scalable data storage solutions as data production and processing increase dramatically. Businesses and organisations need storage solutions to handle growing data volumes [17].

Scalable data storage solutions are needed to manage growing enterprises’ and individuals’ data quantities. Scalable data storage solutions for Blockchain and beyond:

4.9.1 DISTRIBUTED FILE SYSTEMS

Overview: Distributed computing underpins blockchain technology. Distributed computing is just a network of computers that create one system. Physically connected systems form a local network or geographically scattered systems connect online. The old principle has been refined over time to meet needs. Distributed network computers don’t need a predefined format or hardware setup. This could be laptops, mainframes, PCs, or Macs. See Figure 4.5.

FIGURE 4.5 Distributed file system [14].

Examples: Hadoop File System (HDFS), Google Cloud Storage, Amazon S3.

4.9.2 CLOUD-BASED STORAGE

Overview: Blockchain technology has the potential to give cloud computing a decentralised, distributed network of nodes that may exchange data and processing power. Because of this, businesses no longer require the services of a single, centralised source (Figure 4.5). They can rely on a dispersed network of computers that are not centralised to the management of any one particular organisation.

A system like this one has the potential to offer several benefits, including heightened levels of security, improved scalability, and increased availability (Figure 4.6).

FIGURE 4.6 Cloud-based storage [15].

Examples: Amazon Web Services (AWS) S3, Google Cloud Storage, and Microsoft Azure Blob Storage [18].

4.9.3 DATA SHARDING

Overview: Sharding data involves chopping up large amounts of information into more manageable chunks and then spreading those pieces across a network of servers or nodes. Sharding is a technique that divides a network’s workload into sections, intending to lower network latency and increase the number of transactions that a blockchain can process. Decentralisation, scalability [19], and security are three characteristics that blockchain networks are working to implement.

Examples: MongoDB sharding for NoSQL databases and Ethereum block-chain for distributed ledger technology.

4.10 CONCLUSION

In conclusion, blockchain technology in data storage and security systems revolutionises data protection, integrity, and privacy. This exploration has highlighted some significant points that demonstrate Blockchain’s importance and potential:

Immutable Data Integrity: Blockchain’s inherent immutability ensures that, once data is recorded on the Blockchain, it cannot be altered or deleted without consensus [20]. This feature makes it an ideal choice for preserving data integrity, making it resistant to tampering and unauthorised modifications.

Decentralised Trust: The decentralised nature of Blockchain removes the need for a centralised authority or intermediary. This trustless environment empowers individuals and organisations to interact directly, fostering transparency, accountability, and reduced reliance on third parties.

Enhanced Security: Cryptographic techniques, digital signatures, and private–public key pairs bolster the security of data stored on a blockchain. Unauthorised access is mitigated, and data remains confidential while being verifiable by authorised parties.

Smart Contracts: Smart contracts automate processes and enforce agreements, reducing the risk of human error and enhancing security. They facilitate self-executing, tamper-resistant, and trustless transactions, unlocking new possibilities for data security.

Privacy Preservation: Privacy-focused blockchain implementations incorporate techniques such as zero-knowledge proofs and confidential transactions, ensuring that sensitive data remains confidential while benefiting from the blockchain’s security features.

Scalability Solutions: Scalability remains a challenge for blockchain technology, but ongoing research and developments, including sharding and layer-2 solutions, aim to address these limitations and support the growing demands of data storage and processing.

Use Cases and Adoption: Real-world applications in healthcare, finance, supply chain management, and other sectors demonstrate the practicality of Blockchain in enhancing data storage and security. These use cases illustrate the tangible benefits of blockchain adoption.

Challenges and Considerations: Despite its potential, blockchain technology faces challenges, including regulatory compliance, energy consumption concerns, user adoption hurdles, and scalability bottlenecks. These challenges need to be addressed for widespread adoption.

Future Directions: The future of blockchain technology in data storage and security looks promising. Continued innovation, interoperability improvements, and integration with emerging technologies will shape the landscape of secure and efficient data management.

In this age of data-driven decision-making and escalating cybersecurity concerns, blockchain technology for data storage and security appears promising. As enterprises and individuals consider data a crucial asset, strong, tamper-resistant, and privacy-preserving solutions become essential. Blockchain’s decentralised, encrypted, and transparent properties make it a promising solution for these changing needs.

In recent years, the emergence of blockchain technology has transformed various industries, revolutionizing the way transactions are conducted, verified, and recorded. Blockchain, originally devised for Bitcoin, has evolved into a sophisticated system with far-reaching implications beyond cryptocurrency. Its decentralized and immutable nature holds significant promise for enhancing trust, transparency, and efficiency in interorganizational collaborations, particularly within supply chain management. This introduction provides an overview of the research landscape surrounding the impact of blockchain innovation, interorganizational collaboration, and relationship learning on supplier performance, utilizing a bibliometric analysis to discern trends, gaps, and areas for future exploration.

Blockchain technology, often described as a distributed ledger, enables the secure and transparent recording of transactions across multiple parties without the need for intermediaries. Its foundational principles of decentralization, cryptographic security, and consensus mechanisms have propelled it into the spotlight as a disruptive force across various sectors. Reference [1] introduced blockchain as the underlying technology powering Bitcoin, but its applications extend far beyond cryptocurrency. Blockchain’s potential to revolutionize supply chain management lies in its ability to create a single, immutable record of transactions, thereby enhancing transparency, traceability, and accountability [2]. Interorganizational collaboration, characterized by the cooperation between multiple organizations to achieve common goals, is essential for optimizing supply chain performance. Traditional supply chains often suffer from siloed operations, lack of transparency, and inefficiencies resulting from fragmented processes. Blockchain offers a transformative solution by providing a shared, decentralized platform for collaboration, where participants can securely exchange information and assets in real time. By streamlining processes and reducing transaction costs, blockchain fosters trust and cooperation among supply chain partners, leading to enhanced collaboration and collective value creation [3].

Relationship learning encompasses the acquisition, sharing, and application of knowledge within interorganizational relationships to improve performance and adaptability. In the context of supply chain management, effective relationship learning is crucial for building strong, enduring partnerships, and achieving mutual benefits. Blockchain facilitates relationship learning by enabling transparent and auditable record keeping, which enhances trust and accountability among supply chain participants. Through shared access to accurate and up-to-date information, organizations can gain insights into one another’s capabilities, preferences, and performance, leading to more informed decision-making and collaborative problem-solving [4].

Supplier performance is considered part of organization performance that plays a critical role in determining the overall effectiveness and competitiveness of supply chains [5]. Moreover, innovation and sustainable supply chain management practices stimulate suppliers’ performance in emerging economies [6]. High-performing suppliers contribute to cost reduction, product quality improvement, and innovation acceleration, driving value creation throughout the supply network. Blockchain, by improving transparency, trust, and collaboration, has the potential to positively impact supplier performance in several ways. By providing verifiable proof of delivery, quality, and compliance, blockchain reduces the risk of disputes and discrepancies, leading to smoother transactions and stronger relationships between buyers and suppliers [7].

5.2 LITERATURE REVIEW

Technological innovation, interorganizational collaboration, and relationship learning play pivotal roles in shaping modern supply chain management (SCM). This literature review aims to explore the theoretical underpinnings, key concepts associated with technological innovation, interorganizational collaboration, relationship learning, and their interconnectedness with supply chain management.

5.2.1 THEORETICAL BACKGROUND

Technological innovation is the process through which new technologies are developed, adopted, and diffused within organizations. Several theoretical frameworks have been proposed to understand and explain the dynamics of technological innovation. One prominent theory is the technology-organization-environment (TOE) framework [8]. This framework emphasizes the interplay between technological factors, organizational characteristics, and external environmental factors in influencing innovation adoption decisions within firms. Another significant theory is the diffusion of innovations theory [9]. This theory classifies adopters of innovations into categories based on their innovativeness and explores the factors that influence the rate of adoption within a social system. Understanding the diffusion process is essential for managing technological innovation within supply chains and ensuring the successful implementation of new technologies.

Interorganizational collaboration refers to the strategic alliances and partnerships formed between firms to achieve common goals. The transaction cost economics (TCE) theory provides insights into the motivations behind interfirm collaborations by emphasizing the role of transaction costs in determining the governance structure of relationships [10]. According to TCE, firms choose collaboration mechanisms that minimize transaction costs and mitigate risks. Another relevant theory is resource dependence theory, which highlights the importance of resource interdependencies among organizations in driving collaboration [11]. Organizations collaborate to access critical resources, reduce uncertainty, and enhance their competitive advantage in the market. Understanding resource dependencies is crucial for designing effective collaborative strategies within supply chains.

Relationship learning refers to the process through which firms acquire knowledge and insights from their interactions with partners in collaborative relationships. The social exchange theory provides a foundation for understanding relationship learning by emphasizing the reciprocity and mutual benefits that underlie interpersonal relationships. In supply chain contexts, firms engage in collaborative activities to exchange knowledge, share resources, and build trust with their partners. The relational view of competitive advantage posits that sustained competitive advantage arises from the development of unique and valuable relationships with key stake-holders, including suppliers, customers, and partners [12]. According to this view, firms invest in relationship-specific assets and capabilities to enhance collaboration and create value within supply chains.

These theories of technological innovation, interorganizational collaboration, and relationship learning are closely intertwined with supply chain management practices. Technological innovations drive process improvements, product enhancements, and supply chain integration initiatives. Collaborative relationships enable firms to leverage complementary resources, share risks, and achieve economies of scale in their supply chain operations. Relationship learning facilitates knowledge sharing, problem-solving, and continuous improvement within supply chain networks. By leveraging these theoretical frameworks, organizations can enhance their competitive advantage, foster innovation, and build resilient supply chain networks in today’s complex business environment.

5.2.2 BLOCKCHAIN INNOVATION AND SUPPLY CHAIN MANAGEMENT

Blockchain technology has emerged as a disruptive force across various industries, offering transparency, security, and efficiency in data management. In the realm of supply chain management (SCM), blockchain holds promise for transforming traditional practices by providing immutable records, traceability, and decentralized control. This literature review explores the impact of blockchain innovation on SCM, examining its implications for transparency, efficiency, trust, and sustainability. Blockchain’s distributed ledger technology enables real-time tracking of goods and transactions across the supply chain. Reference [13] highlights blockchain’s potential to enhance transparency by recording every transaction in a tamper-proof manner, thereby reducing the risk of fraud and counterfeiting. For instance, in the food industry, blockchain enables end-to-end traceability, allowing consumers to verify the origin and journey of products [14]. Such transparency not only improves consumer trust but also facilitates compliance with regulatory requirements.

By eliminating intermediaries and automating processes, blockchain streamlines SCM operations, leading to cost savings and efficiency gains. Reference [15] identified that blockchain’s smart contracts enable automated execution of predefined terms, such as payment upon delivery or quality verification, reducing administrative overheads and processing times. Moreover, blockchain facilitates seamless information sharing among stakeholders, fostering collaboration and optimization of supply chain processes [16]. These efficiency improvements translate into competitive advantages for businesses, enabling them to respond swiftly to market dynamics. One of blockchain’s key features is its ability to establish trust in decentralized networks without relying on central authorities. Blockchain’s consensus mechanisms and cryptographic techniques ensure data integrity and security, mitigating the risk of data manipulation or unauthorized access [17]. In SCM, this trust enables seamless collaboration among disparate entities, such as suppliers, manufacturers, and distributors, without the need for intermediaries [18]. As a result, blockchain fosters a more resilient and secure supply chain ecosystem, bolstering confidence among stakeholders.

Blockchain has the potential to promote sustainability initiatives and ethical sourcing practices within supply chains. Reference [19] suggests that blockchain-enabled transparency enables consumers to make informed choices about environmentally friendly and ethically produced products. By providing visibility into the production processes and supply chain footprint, blockchain encourages accountability and responsible practices [20]. Furthermore, blockchain can facilitate the verification of certifications, such as fair trade or organic labels, ensuring compliance with sustainability standards [21]. Thus blockchain not only enhances supply chain efficiency but also contributes to broader social and environmental goals. Despite its potential benefits, blockchain adoption in SCM faces several challenges and limitations. Technical barriers, such as scalability, interoperability, and data privacy, pose significant hurdles to widespread implementation [3]. Moreover, the transition from legacy systems to blockchain-enabled platforms require substantial investments in infrastructure and skill development [16]. Additionally, regulatory uncertainties and industry fragmentation impede standardization efforts and hinder ecosystem-wide adoption [15]. Addressing these challenges necessitates collaborative efforts from industry stakeholders, policymakers, and technology providers.

5.2.3 IO COLLABORATION AND SUPPLY CHAIN MANAGEMENT

Interorganizational collaboration in the context of SCM encompasses a spectrum of collaborative activities among supply chain partners, including information sharing, joint decision-making, resource pooling, and joint product development [22]. The conceptual framework for understanding interorganizational collaboration often incorporates elements such as trust, communication, shared goals, and mutual benefits [23]. One of the primary benefits of interorganizational collaboration is improved information sharing across supply chain partners. By sharing real-time data on demand forecasts, inventory levels, and production schedules, organizations can achieve greater visibility and responsiveness in their supply chains [24]. Moreover, effective information sharing reduces uncertainty and enhances coordination, leading to lower inventory costs and improved customer service levels [25].

Interorganizational collaboration facilitates coordination and integration of processes across the supply chain. Through collaborative planning, forecasting, and replenishment (CPFR) initiatives, organizations can synchronize their activities and align inventory levels with demand fluctuations [26]. Such coordination minimizes stockouts, reduces lead times, and enhances overall supply chain efficiency [27]. Collaborative relationships enable supply chain partners to jointly innovate and develop new products or services. By pooling resources and expertise, organizations can accelerate the pace of innovation and bring products to market faster [28]. Reference [29] underscores the importance of collaborative product design and co-creation in fostering competitive advantage and market differentiation.

Interorganizational collaboration plays a crucial role in mitigating supply chain risks. By sharing risk assessments and implementing joint risk mitigation strategies, organizations can build resilience and adaptability in the face of disruptions [16]. Collaborative approaches to risk management include supplier diversification, redundant capacity planning, and disaster recovery planning [30]. The success of interorganizational collaboration hinges on the quality of relationships and levels of trust between supply chain partners. Reference [31] emphasizes the role of trust in facilitating open communication, conflict resolution, and knowledge sharing among collaborators. High levels of trust lead to stronger partnerships, increased commitment, and mutual benefits for all parties involved.

Several studies have investigated the impact of interorganizational collaboration on SCM performance outcomes. Organizations with higher levels of collaboration achieve greater supply chain agility, responsiveness, and cost efficiency [32]. Similarly, reference [33] observed a positive correlation between collaboration intensity and supply chain performance metrics such as on-time delivery and order fulfilment rates. Interorganizational collaboration is a multifaceted strategy that holds immense potential for improving supply chain management practices. As businesses continue to navigate complex supply chain challenges, investing in collaborative partnerships remains essential for achieving sustainable growth and resilience.

5.2.4 RELATIONSHIP LEARNING AND SUPPLY CHAIN MANAGEMENT

Relationship learning is rooted in organizational learning theory, which emphasizes the acquisition, interpretation, and integration of knowledge within interorganizational relationships [34]. According to this perspective, organizations engage in learning processes through repeated interactions with supply chain partners, leading to the accumulation of shared knowledge and capabilities [12]. This shared understanding enhances coordination, trust, and commitment among supply chain members, ultimately improving overall performance [35].

Numerous empirical studies have investigated the impact of relationship learning on various aspects of supply chain management. For instance, reference [36] found that relationship learning positively influences supply chain integration, leading to enhanced information sharing, joint decision-making, and operational coordination. Similarly, relationship learning fosters collaborative innovation within supply chains, enabling partners to jointly develop new products and processes [37].

Moreover, studies have highlighted the role of relationship learning in mitigating supply chain risks. For example, firms with high levels of relationship learning are better equipped to anticipate and respond to disruptions and enhance the understanding of partners’ capabilities and vulnerabilities [38]. This suggests that relationship learning contributes to the resilience and agility of supply chains in an increasingly volatile business environment. Practically, fostering relationship learning requires proactive efforts from supply chain managers and executives. This entails investing in mechanisms and initiatives that facilitate knowledge exchange and collaboration among partners. For instance, joint training programs, cross-functional teams, and shared performance metrics can promote learning and alignment across organizational boundaries [39].

Furthermore, organizations can leverage technology to enhance relationship learning within their supply chains. Digital platforms and e-systems such as collaborative planning systems and supply chain analytics tools, enable real-time information sharing and visibility, facilitating continuous learning and improvement [40]. By embracing these technological solutions, firms can strengthen their relationships with suppliers, customers, and other stakeholders, thereby enhancing the overall resilience and competitiveness of their supply chains [24].

6.1 INTRODUCTION

In the rapidly emerging outlook of technology, blockchain is an evolving breakthrough that improves the way data, transactions, and trust are handled. The blockchain serves as an immutable ledger because data cannot be modified or erased once it is added to the blockchain. As a result, blockchain is a secure and trustworthy method of preserving data. Every blockchain starts with a genesis block, which acts as a basis for the chain. This first block is the beginning of a new phase in data management, where consensus protocols and cryptographic methods combine to generate an invincible digital record. A block consists of a header partition comprising the original data, and a block body also consists of the hash value indexing the previous blocks. A hash function is used in every blockchain transaction. It ensures the safety of the block-chain. Embracing the principles of decentralization, blockchain distributes its ledger across multiple nodes in a network, each node maintaining a replica of the complete chain. This self-sustainable peer-to-peer (P2P) network drives the evolution of blockchain technology. To avoid chain breakage, it is necessary to modify the hash values of all blocks behind the block at the same time. As a result, a large computational complexity is needed, and the security of the blockchain is not guaranteed [1]. Various applications of blockchain technology demonstrate its versatility. Blockchain technology has limitless potential, which can be seen in everything from the specific tracking of goods, as shown in Denmark’s supply chain management, to the execution of smart contracts on platforms like Ethereum. Due to the transparent and tamper-proof characteristics of blockchain transactions, international wire transfers acquire a new level of efficiency and security. Blockchain is a trustworthy platform for a variety of applications. In this chapter, we embark on the expedition through the complexities of blockchain technology, studying its immutable basis, understanding the potential of distributed networks, and determining how to use it in real-world scenarios.

6.2 CHALLENGES IN CENTRALIZED DATA STORAGE

Centralized storage refers to the storing of data at a single location in a controlled environment. In this model, the data is stored on a central server or group of servers managed by a single entity organization. As shown in Figure 6.1, the client–server model demonstrates that these entities are responsible for the entire data management and security stored on the server. A centralized server works on the principle of the client–server model, in which there is a centralized server managing the connected clients within the network. A centralized server could be a physical server, a data center, or a third-party cloud service. This server can be vulnerable to a single point of failure. If the central server or data center faces any hardware failures, cyberat-tack or any natural disaster, then all the data can be compromised. Hackers tend to look for centralized storage as a target. Once the data is compromised, it may lead to unauthorized access, data leakage, and privacy violations. Since the entity has full control over the data, users trust these centralized bodies to manage their data ethically and securely without full transparency into how their data is being handled.

FIGURE 6.1 Client–server model.

6.3 P2P DATA WAREHOUSING

Decentralized systems extend the traditional centralized systems. Instead of depending upon a single central server, just think how fascinating it would be to store the entire data in different places to protect it within a network. This is possible because of the decentralized systems, which distribute the data across every node participating in the network using blockchain technology. This approach offers improved security and more reliability and user control over the data. As shown in Figure 6.2, a decentralized system utilizes peer-to-peer network architecture to facilitate the distribution and management of the data or transactions. In a P2P network, individual nodes communicate with one another in a network. Each node can concurrently request and provide resources to other nodes, acting as both a client and a server. A decentralized system distributes the data across the network by breaking it into blocks. These blocks of data are then replicated and stored on multiple nodes in a network. Decentralized systems rely on the redundancy of data across multiple nodes to achieve reliability. If one node becomes unavailable or fails, the data can still be retrieved from other nodes, ensuring data availability. When a node in the network wants to retrieve specific data, it sends a request to other nodes in the network. The requested data is then retrieved from the nodes that hold replicas of the data. Consensus mechanisms are often used in decentralized systems to ensure the accuracy and consistency of the data stored on different nodes.

FIGURE 6.2 Distributed P2P network consisting of blockchain.

6.3.1 CONSENSUS MECHANISM

Consensus mechanisms are protocols that ensure consistency and agreement among participants of a decentralized network. They make it feasible for nodes to independently validate transactions, determine the system’s status, and preserve data integrity. They enable network participants to validate and agree upon transactions before they are added to the blockchain, preventing intruders from initiating invalid transactions or modifying data. Double spending is an instance where the same digital asset is used twice and is prevented by the consensus procedure. Consensus assures that each asset can only be used once by agreeing on the sequence and validity of transactions. Once a transaction is added to the blockchain and its accuracy is verified, it is quite difficult to modify it. In decentralized systems, consensus ensures the immutability and integrity of the data within the network.

6.3.1.1 Proof-of-Work (POW)

PoW is a consensus mechanism used in blockchain networks, where the participants, known as miners, compete to solve a complex mathematical problem to create a new block and validate the transactions. For our timestamp network, we implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits [2].

6.3.1.2 Proof-of-Stake (PoS)

A PoS mechanism selects validators to add new blocks and approve transactions based on how much cryptocurrency they own and are prepared to “stake” as security. These validators have a financial stake at risk, which incentivizes them to approve only legitimate transactions. This consensus among nodes establishes a strong and invincible ledger where data is safely kept, serving as a fundamental pillar for ensuring the reliability and integrity of decentralized data storage solutions. Consensus mechanisms essentially give decentralized systems the ability to protect data, build trust, and keep the pledges of transparency and security that are at the core of block-chain technology.

6.3.2 SMART CONTRACTS AND DATA MANAGEMENT

Bitcoin Crypto in blockchain executes a simple transfer of digital currency with an agreement. Ethereum is based on the concept of smart contracts with more complex scripts run by the arbitrary nodes. Smart contracts are executable scripts running in a blockchain environment and comprise of contractual terms and conditions [2]. The term “smart contracts” was coined in 1994 by American computer scientist Nick Szabo, who realized that the decentralized ledger could be used for smart contracts [3]. Smart contracts automate processes by eliminating the need for intermediaries to execute or verify transactions. Smart contracts can carry arbitrary state and can perform any arbitrary computations [3]. Smart contracts improve the way data is managed on blockchains by ensuring its accuracy, security, and efficiency. Data on a blockchain is stored in a decentralized immutable ledger. Data is grouped into blocks, that are linked sequentially to form a chain. Transactions contain the actual data and are added to blocks. Each participant in the network maintains a replica of the sequential chain containing the data, ensuring redundancy, and reducing the risk of a single point of failure. These data are encrypted using cryptographic hashing techniques, enhancing data security. Hashing generates unique, fixed-length codes from data, making it highly resistant to tampering. Blockchain networks use consensus mechanisms to agree on the validity of transactions before they’re added to the ledger. Smart contracts automate data management by executing predefined actions based on specific conditions. They enable trustless and self-enforcing agreements. In summary, storing and managing data on a blockchain offers benefits such as enhanced data security, transparency, and efficiency.

6.3.3 OFF-CHAIN DATA SOLUTIONS

Off-chain data solutions offer ways for storing data off the primary blockchain while still using these aspects for security and verification in certain aspects of the process. Data hash creates a cryptographic hash of the data and stores it on the blockchain. The hash serves as proof for the validity and existence of the data (Figure 6.3). Sidechains set up secondary chains that are capable of handling specific data-intensive tasks and are connected to the main blockchain for security and verification. State channels reduce the need for on-chain transactions for each connection and provide private off-chain channels for transactions between participants. On-chain storage is more expensive in terms of computing and storage; off-chain storage is less expensive. By storing huge amounts of data off-chain, scalability problems that occur from doing so are reduced.

FIGURE 6.3 On-chain and off-chain.

6.4 SECURITY CHALLENGES: BLOCKCHAIN

Secure blockchain systems build trust among users and stakeholders; enhancing these security measures ensures the long-term viability of blockchain-based solutions by mitigating vulnerabilities and risks. Addressing security challenges reduces the economic impact of attacks, preventing financial losses for individuals and organizations.

6.4.1 NETWORK COHESION: FORKS AND CHAIN SPLITS

The cohesive and synchronized state of a blockchain network is referred to as network cohesion. When the network’s consensus is broken, it might result in forks and chain splits, which could cause splitting and deviation. A hard fork occurs when a protocol update permanently diverges the blockchain into two incompatible chains. A soft fork maintains backward compatibility between the new and old rules. Although it doesn’t result in a permanent split, it can cause a brief divergence. A chain split occurs when there is a protracted disagreement among members, resulting in two separate chains, each with its own consensus rules. Forks and chain splits can be triggered by disagreements over protocol changes, consensus rules, or other critical decisions. As some participants could follow one chain while others follow another, forks and chain splits can cause data inconsistencies and misunderstandings among participants. Network cohesiveness is greatly impacted by the consensus mechanism chosen, such as proof-of-work (PoW) or proof-of-stake (PoS). Participants are guaranteed to agree on protocol changes using consensus processes. Examine the major hard forks, like the splits in Ethereum Classic and Bitcoin Cash, demonstrated in Figures 6.4 and 6.5, specifically how they affect the cohesiveness of networks.

FIGURE 6.4 Hard fork: e.g., Ethereum.

FIGURE 6.5 Soft fork: e.g., Bitcoin.

6.4.2 DOUBLE SPENDING

The act of using a digital asset more than once is known as double spending, which essentially results in a fraudulent transaction. In Figure 6.6, it explains the problem with digital currencies since they involve decentralized, unreliable transactions. Digital assets can be duplicated, in contrast to actual cash. Without sufficient safeguards, there is a chance that someone may use this to spend the same money more than once. As blockchain-based systems and digital currencies depend on transparency and immutability, understanding double spending is essential for fostering trust in them. Double spending is reduced by consensus mechanisms like proof-of-work (PoW) and proof-of-stake (PoS), which validate transactions. The probability of a fraudulent double spending attack is minimized by waiting for a certain number of network participant confirmations. Implementing transaction fees encourages miners or validators to choose legitimate transactions over fraudulent ones. The block-chain community can effectively reduce the risks associated with double spending by putting in place safeguards like consensus processes, transaction confirmation, transaction fees, and leveraging technology breakthroughs like smart contracts. These tactics help decentralized payment systems gain more acceptance and trust while also enhancing the security of digital currency.

FIGURE 6.6 Double spending.

6.5 SOLUTIONS FOR ENSURING DATA SECURITY

Securely encrypting sensitive data before storing it on the blockchain makes sure that only permitted users can access the decrypted data. To convert data into fixed-length codes (hashes), use cryptographic hashing techniques. Data integrity is ensured by hashes since they are irreversible and distinct. To restrict access to data, use key pairs that are both public and private. Private keys allow access to the data while public keys help identify users. To improve security and lower the chance of unauthorized access, we require the approval of multiple authorized individuals before completing transactions.

6.5.1 CRYPTOGRAPHIC HASH FUNCTIONS

Cryptographic hash functions convert an input (such as a message or set of data) into a fixed-size output (the hash or message digest). The output contains several crucial characteristics that make it valuable for applications in cryptography and other fields [4]:

Deterministic: Every time a particular input is used, a hash function must always yield the same result. This characteristic is crucial to cryptography since it enables the authentication and verification of a message or piece of data [5].

Collision Resistance: It should be computationally impossible to identify two inputs that have the same output using a hash function. As it prohibits an attacker from changing a message without also changing the hash, this characteristic is crucial in cryptography, since any modification to the input would change the hash.

Fast Computation: A hash function should be computationally efficient, which means that it should be possible to compute the hash rapidly and effectively for huge inputs. This property is crucial in a variety of uses for the hash function, including digital signatures and cryptocurrencies.

Avalanche Effect: A hash function should produce output that seems consistently random. That implies that every bit in the output should be separate from the others. Since it prevents an attacker from inferring any information about the input using knowledge of the output, this property is crucial in cryptography.

6.5.2 ENCRYPTION TECHNIQUE

Encryption methods act as a persistent defender in all aspects of data storage on the blockchain, safeguarding the security, confidentiality, and privacy of sensitive data. Data is converted into an unreadable format during encryption by using cryptographic methods and keys. The change makes the data unreadable to unauthorized people, protecting it against harmful intended use. Understanding encryption methods is of significance in the context of blockchain technology because it is essential to protecting the most valuable currency of the digital age: data. Symmetric encryption, a single shared key is used by symmetric encryption for both encryption and decryption. The difficulty is in the secure distribution of the secret key to authorized parties, even though it is effective for quick data processing. The same key can be securely exchanged between participants in this method’s appropriate settings. In asymmetric encryption, a pair of keys is used for asymmetric encryption: a public key for encryption and a private key for decryption. Anyone can encrypt data using the public key, which can be distributed widely, but only the owner of the private key is able to decrypt it and retrieve the original data. This technique is a cornerstone of data security since it assures secure communication and digital signatures. To protect encryption keys, use strict key management procedures. These keys could be compromised if unauthorized access gets access to them. To ensure that keys are only accessible to authorized people, use hardware security modules (HSMs) and access controls. Apply end-to-end encryption to the transmission of data. By ensuring that data is encrypted while in transit, hostile parties cannot intercept it. It is common practice to use RSA encryption—Rivest, Shamir, and Adleman—for secure communication and digital signatures. Asymmetric encryption is used by the RSA method to enable safe data transfer between parties who have the right decryption keys. Advanced encryption standard (AES), a symmetric encryption technique renowned for its effectiveness and security, is a further well-known example. Due to its resistance to brute force attacks, AES encryption is often used to safeguard data both while it is in transit and when it is at leisure.

6.6 FUTURE TRENDS AND TECHNOLOGY

These trends and technologies are likely to influence the future trajectory of block-chain technology as it continues to develop and adapt to different industries, enabling creative solutions and changing how data and transactions are managed globally.

Multichain Solutions: It is anticipated that multichain solutions and interoperability standards will develop, enabling secure data sharing and communication between different blockchain networks. This will make it possible for applications to be developed that are more intricate and varied and that use different blockchain platforms.

Integration with Internet of Things (IoT): IoT and blockchain, working together, have a lot of possibilities. The secure data sharing and provenance tracking capabilities of blockchain fit nicely with the requirements of IoT devices. Interactions between IoT devices may be automated, and tamper-proof data storage may improve data integrity in interconnected ecosystems [6].

Blockchain in Supply Chain and Logistics: The transparency and tracking capabilities of blockchain tend to play a critical role in improving supply chain management, building on existing use cases. The origin and travel of items will be made authentic and real-time data available to consumers.

6.7 CONCLUSION

In conclusion, the rapidly evolving digital landscape has brought in the era of block-chain, a revolutionary technology that fundamentally transforms how data, transactions, and trust are managed. Blockchain provides the security and dependability of data by preventing unauthorized modifications with its immutable ledger. In these networks, consensus procedures are essential for preserving data integrity, accuracy, and transparency. Mechanisms for proof-of-work and proof-of-stake both increase confidence, enabling secure transactions and reducing fraud like duplicate spending. The potential of blockchain is limitless as we navigate this rapidly changing environment. Applications like supply chain management, smart contracts, and safe international wire transfers are examples of how it appears. Blockchain opens the path for a future of secure, transparent, and effective data management across a variety of industries by comprehending and addressing security concerns and utilizing its inherent capabilities. The exploration of blockchain technology’s complexity, from its immutable basis to distributed networks, confirms its potential to be an essential tool in the current digital era.

7 Ethics Involved in Blockchain Technology A Concise Update

K.R. Padma and K.R. Don

DOI: 10.1201/9781032654812-7

7.1 INTRODUCTION

Organizations by their very nature are dynamic. The gig economy [1], frequent job switching [2], new communication techniques [3], globalization of the labour force [4], and technological advancement [5] are some of the factors that have affected the dynamic change of organizations in recent years. The COVID-19 epidemic greatly expedited technological disruption, which has most significantly caused “years of change” in organizational behaviour. Emerging technologies have accelerated organizational change, which cannot be denied.

The fundamental flowchart for accounting data has been the same for hundreds of years. A business keeps track of its own transactions and reports them. It is inevitable that this simple information flowchart eventually come to an end due to technological trends. In the future, each transaction will be recorded by a variety of parties, and many (perhaps an infinite variety of parties) will keep encrypted records of those transactions. Anyone with access to those records will be able to produce financial reports based on those transactions. Distributed ledger technology (DLT) refers to this relatively new concept. We also call it a blockchain ledger because it is based on block-chain technology. There is an overarching framework for Linux called Hyperledger. Hyperledger [6] said, “Contracts”, exchanges, transactions, or merely items we never want to lose can be recorded on blockchain technology. Since the common system of record is precisely replicated across all nodes in a given network, it allows everyone in the ecosystem to maintain a copy of it. You can never alter or remove any information.

Bitcoin and other cryptocurrencies are supported by the distributed ledger technology known as blockchain [7]. But its application is rapidly spreading outside the financial sector and into other spheres of society [8, 9]. Blockchain offers disruptive improvements in technology, economic models, and social governance that have the potential to be as revolutionary as the internet and artificial intelligence. In order to support large-scale applications, blockchain offers a trustless computing architecture that has the ability to address basic trust issues and enable direct exchange of goods and services. See Figure 7.1, which depicts the framework structure of ethics involved in blockchain.

FIGURE 7.1 Framework structure of ethics involved in blockchain.

Due to its ability to increase transparency, security, and sharing to unprecedented levels, blockchain has great promise for expanding the digital economy and society.

High-tech applications and solutions are being produced by the blockchain industry, which is seeing a surge in entrepreneurship worldwide. Although blockchain firms have recently experienced an incredible rise, there have only been a few real-world applications. Thus governments and other institutions are actively and closely following blockchain’s development. In part because a lot of moral and ethical difficul-ties still need to be overcome before blockchain adoption can be completely justified, there are still questions regarding blockchain and its applications.

How blockchain ethics research should be set up is the primary research question. This study presents a conceptual model of blockchain ethics from an information systems perspective in an attempt to offer a first answer. The paper initially analyses the fundamental ideas of blockchain and enumerates its most important and well-known applications, laying the foundation for the conceptual model. The second section of the study covers the state of the research and discusses how the conceptual model that is being suggested is derived from it. The third section introduces the conceptual model of blockchain ethics that has been suggested, which is meant to serve as a guide for further research. This conceptual model is designed to cover the main ethical concerns of cryptocurrencies and other blockchain applications in a systematic manner. The study also recommends potential future research directions.

7.2 ETHICS IN BLOCKCHAIN

Blockchain technology was used to introduce the most recent iteration of the internet. Zachariadis et al. [10] asserts that blockchain is a disruptive technology that could change social relationships, financial transactions, and possibly even society. Blockchain is not a specific definition but rather an umbrella term for a number of different components that were established as the foundation for Bitcoin based on a distributed system, according to Narayanan and Clark [11]. Because blockchain software applications are increasingly popular, businesses and society are greatly impacted by this technology [12]. Due to its unique characteristics, blockchain technology has the power to change worker involvement within a company. Immutability is a property of blockchain technology that makes it harder or impossible for managers to keep an eye on company transactions [13].

In light of this, it is prohibited to commit fraud or utilise information for personal gain by stealing it or distorting it [14]. According to Tapscott and Tapscott [15], the openness that blockchain technology delivers to business operations and ethical standards like decency, thoughtfulness, and accountability allows for accurate executive service tracking and asset assessment. According to Catalini and Tucker [16], the distributable information architecture of the blockchain network makes it a powerful tool for combating organizational rivalry. Because it allows for information access and openness for all users, this technology is used in a way that respects both human rights and citizenship rights [17].

In blockchain networks, adherence to laws and regulations is crucial [18]. The connection between blockchain technology and moral dilemmas has been the subject of numerous research works. According to Fischer [19], blockchain technology can be used successfully to address ethical issues in accounting and finance. Tang et al. [20] offered a framework for the ethical principles of the blockchain, according to understanding, technology, application, and regulation (UTAR). Therefore, stakeholders must be informed about the advantages and ethical dilemmas posed by blockchain technology. Second, using blockchain as a new technology means that moral principles need to be taken into account. Then ethical standards must guide the use of blockchain apps, and blockchain-based applications themselves must follow ethical standards. Figure 7.2 presents the ethical design framework for blockchain-based applications.

FIGURE 7.2 Ethical design framework for blockchain-based applications.

7.3 BITCOIN AND CRYPTOCURRENCY IN BLOCKCHAIN TECHNOLOGY

Many people conflate the phrases “blockchain,” “bitcoin,” and “cryptocurrency.” This is regrettable since it leads to a swaying interest in other facets of blockchain technology, reflecting the excitement and buzz around the extremely volatile Bitcoin [21]. The largest cryptocurrency is Bitcoin, which peaked in value at $300 billion in 2017 [22]. Bitcoin is the best known example of a cryptocurrency. Despite the fact that Nakamoto [7] created both Bitcoin and blockchain, Bitcoin is merely a one-use case for the technology. JP Morgan CEO Jamie Dimon, for instance, is well-known for his criticism of Bitcoin, although his company has embraced other blockchain-related uses [23].

When describing the architecture of Bitcoin and identifying the source, Nakamoto [7] even uses the word “Bitcoin” in the title. However, Nakamoto’s technology is the blockchain technology that underpins Bitcoin, which also has other applications that could potentially be applied to it. The pros, cons, and ambivalent characteristics of cryptocurrencies like bitcoin are described by Dierksmeir and Seele [24]. Even though distributed ledgers and cryptocurrencies both employ blockchain technology, they have different ethical standards. Taking the possibility of tax avoidance as an example, Dierksmeir and Seele criticise cryptocurrency. Yet distributed ledgers minimise options for tax evasion, producing a morally positive outcome.

Businesses like IBM have adopted blockchain as a tool for a variety of business activities. An open-source initiative named Hyperledger is responsible for block-chain business processes. Contrary to its name, Hyperledger serves a broad spectrum of corporate functions beyond accounting. This chapter’s goal is to identify ethical concerns, challenges, and opportunities pertaining to Hyperledger technology in general and to financial account accuracy in particular. Distributed ledgers can be usefully compared to Dropbox for the technologically uninitiated because they maintain the same record across various devices and update each device to reflect changes made on all other devices.

7.4 ETHICAL APPLICATIONS BASED ON BLOCKCHAIN TECHNOLOGY

To understand blockchain ethics, it is imperative to illustrate the application possibilities of blockchain technology. Table 7.1 shows how many and how diverse block-chain applications are feasible.

TABLE 7.1 Significant Benefits of Blockchain Technology

Most Common Areas | Potential Benefits
Cybersecurity | IoT security and control; identity protection; privacy protection; protection of critical infrastructure
Finance | Exchanges, banking, insurance, micropayments, P2P lending, crowdfunding, cross-border payments, e-commerce, cryptocurrencies
Smart contracts | Autonomous markets, autonomous communities, autonomous organizations, autonomous transactions, legal systems based on algorithms
Digital property | Healthcare record sharing, supply chain monitoring, intellectual property, artwork registration, identity management, copyright management, real estate registry

The safe nature of blockchain can lead to several opportunities in the fields of supply chain management, data protection, ownership identification, tracking documents, exchanging medical records, real estate registration, and copyright management. Big data, artificial intelligence, and blockchain-based developments like cryptocurrencies are influencing the direction of the financial sector [25]. Blockchain guarantees data integrity, openness, and effective sharing of data assets. Algorithms and artificial intelligence cannot be morally developed without such transparency [26]. In terms of cybersecurity, blockchain can improve data and system security by offering reliable solutions in situations when threats are ongoing, settings are complex, and traditional measurements are costly. Furthermore, there is potential for smart contract applications in a wide range of industries, including finance, trading, supply chains, insurance, and governance. These applications have profound effects on society on several fronts.

7.5 SOCIAL SUSTAINABILITY IS POSITIVELY IMPACTED BY BUSINESS ETHICS

According to Krechovská and Prochazkova [27], corporate sustainability refers to the ability of enterprises to have a beneficial influence on social, economic, and environmental development through their market presence and governance practices. Elgammal [28] found that among small businesses in the Middle East and North Africa, corporate governance positively impacts social responsibility. According to Schrobback and Meath [29], evaluating corporate sustainability strategies necessitates a rigorous approach. They also provided a framework that shows how sustainability strategies fit within corporate sustainability governance. The board’s composition affects the organization’s sustainability performance. Furthermore, the organization’s environmental performance is enhanced by the diversity of the board and the CEO’s isolation from the head of the board [30]. Figure 7.3 presents the recommended theoretical framework for social sustainability on business ethics.

FIGURE 7.3 Recommended theoretical framework for social sustainability on business ethics.

The majority of nations in the Middle East are classified as developing countries, with their economies predominantly reliant on oil production. This region accounts for over 64.5% of the oil output of OPEC. The five countries with the highest oil reserves are Iran (155.60 billion barrels), Iraq (145.02 billion barrels), Kuwait (101.50 billion barrels), Saudi Arabia (97.80 billion barrels), and the United Arab Emirates (97.80 billion barrels), making them the leading oil exporters globally (OPEC, 2019). Consequently, natural resources significantly influence the economic landscape of Middle Eastern nations. Both the Middle East and Sub-Saharan Africa are semi-arid regions in Asia that face considerable challenges related to water scarcity. Research by Yazdanpanah et al. [31] indicates that Iran, along with other countries in the region, is expected to experience a severe drought crisis within the next three decades. Additionally, Schwartz [32] investigation into business ethics highlights the growing concern among Middle Eastern populations regarding environmental issues. Therefore, it is crucial to conduct thorough assessments of sustainability practices and explore the most effective methods for utilizing natural resources while ensuring the well-being of future generations. Investigating the elements that contribute to social sustainability is essential.

7.6 ETHICALLY UNFAVOURABLE APPLICATIONS OF BLOCKCHAIN TECHNOLOGY

Blockchain technology often causes such severe damage to ethically dubious business applications that it provides further evidence of the topic’s ethical importance. For the technology’s prosocial capabilities, the same is true in reverse, as the next section demonstrates. In any scenario, as the following carefully chosen use examples demonstrate, blockchain has the enormous potential to completely transform how people engage in society and business on a worldwide scale. It’s commonly recognised that a large number of cryptocurrencies built on blockchain technology facilitate criminal operations such as money laundering and the sale of firearms, drugs, and pornography through anonymous black markets [33].

Apart from instances involving currency, blockchain technology permits additional forms of illicit and/or unethical transactions by removing the need for intermediaries who can be held directly responsible for the transactions. The “assassination markets” are one example. AUGUR is a blockchain application built on Ethereum that enables the establishment of “peer-to-peer prediction markets” where users can make covert bets [34]. Death pools are a regular sight in traditional prediction markets already. However, AUGUR has now produced what may be considered a true “assassination market” [35] because it permits the placing of anonymous wagers on a person’s demise, which could encourage people to kill others in order to profit from this specific betting.

“Cryptojacking” is another term for programmes that steal cryptocurrency; they are considered criminal activities [36]. Users were initially duped into downloading software that engaged in cryptojacking, but this type of malware is increasingly infecting widely used browsers as well. More processing power on the hacked machine means that hackers could generate a greater profit via cryptojacking software. Thus firms that use high-performance computers and are part of essential infrastructure have become targets for cryptojackers. The public pays a price for their private gain-seeking because public utilities and infrastructure providers regularly use such computing technology [37].

7.7 FAVOURABLE ETHICAL BLOCKCHAIN TECHNOLOGY

We focus on blockchain applications in this section that, although now useful, may not seem contentious at first and have clear corporate ethical consequences. According to Griffiths [38], most academics concur that blockchain 2.0 and 3.0 applications, particularly when paired with the internet of things (IoT), are creating entirely new avenues for international trade and cooperation [8]. These developments frequently have quite favourable social effects. The topic of “blockchain for good” has already generated discussion in response to this [39].

Have a look at VeChain’s partners for partnerships: For example, PwC [40] is assisting in the monitoring of the real-world application of VeChain’s blockchain; Deutsche Bahn/Schenker is in charge of a logistics pilot project; VeChain and the Norwegian registrar company DNV GL are co-developing a digital system to improve the reliability of blockchain data by providing certified assurances about the data input. Considering the vital role that assurance plays in CSR information, blockchain-based supply chain applications constitute a significant step towards the datafication of corporate ethical standards [41]. However, by assuring that there are no child labour or human rights violations during production, or by demonstrating to consumers how environmentally friendly the items are, these applications are likely to have an impact on consumers’ opinions of the products they monitor.

Likewise, Native Americans often face similar challenges when it comes to proving their identity to potential lenders. In the current global economy, where fintechs and social banks are ready to service customers from the bottom of the pyramid, borrowers could gain access. With blockchain-based identity corroboration systems, their options for lenders would no longer be restricted to (potentially) exorbitant ones in their local communities. Thus by implementing blockchain technology, institutional leapfrogging may allow developing countries to improve economically and legally.

There are blockchain utilisations that defy straightforward classifications as morally good or bad. Actually, the different ethical lenses they use affect how they view morality. These moral conundrums are intended to be highlighted by the following examples, which focus on (1) trustless trust, (2) job platforms, and (3) privacy and secrecy. The subsequent portions of this study will give various ethical interpretations of currently accessible applications, drawing on utilitarian, contractarian, deontological, and virtue ethical viewpoints.

7.8 ETHICAL THEORIES

The selected ethical framework influences the normative value of an ethical decision in some way. The approach we have adopted is based on the elements of an act and its a priori state. The three perspectives from which acts might be viewed are typically those of the agent performing the act, the act itself, and the act’s consequences. Ethical philosophies have developed a focus on each of these elements. Although there are moments when it is difficult to distinguish between the many ethical theories, this framework allows for an organised ethical investigation, and that’s what this chapter aims to accomplish. Ethics has always addressed transcendental values that are intrinsically moral, regardless of the consequences they cause or actors who live by them. This is the theory that places a strong emphasis on moral qualities. In virtue ethics, a deed is evaluated in relation to particular virtues. The virtue ethics approach includes many of the virtues that are recognised in the corporate world.

Among these values are integrity, trust, justice, fairness, honour, dependability, integrity, consistency, credibility, and wisdom; see, for example, [42–52]. We believe that virtue ethics gains by emphasizing human potential, particularly in the context of the ongoing debate [53].

Utilitarianism grounds its ethical argument on the outcomes of a specific action, in contrast to virtue ethics. According to Hansen [54], Hunt and Vasquez-Parraga [55], and Louden [56], this tactic is a teleological approach that is focused on ultimate rewards and punishments and believes that actions are justifiable if they serve the majority. Utilitarians believe the guiding principle is to maximise happiness for the greatest number of individuals. Utilitarians take into account a decision’s overall implications, both good and bad.

As opposed to utilitarianism, which determines the morality of an action based on its consequences, deontology is an agent-centred, norm-based ethical theory. Deontology holds that regardless of the outcome, individuals have a moral obligation to act morally in accordance with a particular set of principles and values. Deontologists hold that some values are absolute and should always be respected, such as honesty [57, 58]. A set of rules and agents’ duties determine whether an activity is good or bad [59]. One of the deontological perspective’s negative obligations is the duty to do no harm [60], which may be pertinent given the topic of debate at hand.

A different ethical viewpoint frames the ethics of deeds a priori and blindfolds ignorance. Contractarianism (Rawls) takes an impartial stance on ethics, disregarding social status. According to this method, society is in some sort of consensus among all of its members [61]. The ideals of equality and equal liberty are the two main tenets put out by Rawls [62]. Every person has an equal right to the most fundamental liberties, according to the first principle. According to the second premise, economic concepts should fulfil two criteria. First, a bigger number of advantages must be given to the least advantaged members of society. Equality of opportunity and equal chance for all people are the second prerequisite.

7.9 RESTRICTIONS OF STUDY AND FUTURE STUDIES

Among them are high hardware requirements and sharp energy consumption. It takes a long time to complete the transaction as well. It is imperative that we handle this important issue. Improved coin generation efficiency could boost profitability for the mining sector and help blockchain technology become more widely used. Many enterprises might lower their carbon footprints by incorporating blockchain technology into many facets of economic activity. According to Purvis et al. [63], there are three primary subcategories of sustainability: economic, environmental, and social factors. The sustainability–resilience concept was also introduced by Rai et al. [64], who mentioned the economic and social components of sustainability. Upadhyay et al. [65] identified numerous problems with blockchain technology, including open network architecture, security and privacy, resource waste, energy consumption, lack of interoperability, and scalability. The study’s focus on the social aspect of sustainability meant that the environmental impacts and natural resource consumption associated with blockchain deployment were not thoroughly assessed, which is regarded as a research limitation.

It is recommended that future studies examine concepts like corporate social responsibility and social capital as potential mediating variables in the model. Using precise statistical computations to estimate variables was one of the study’s additional drawbacks. Since uncertain values, like fuzzy or grey techniques, are employed, it is recommended to evaluate the model variables using uncertain ways in order to acquire more realistic results. The following queries should be taken into account for upcoming blockchain research:

What impact might blockchain have on sustainable development?

Which blockchain design lends itself better to sustainability?

Considering how blockchain affects societal sustainability, does it promote good governance?

7.10 CONCLUSION

This study presents the results of an initial investigation into the ethical concerns of blockchain. We provide a conceptual model that arranges the ethical aspects of the four primary blockchain application domains—smart contracts, blockchain decentralization, cryptocurrencies, and the technical stack—after summarizing the core principles underlying blockchain technology and its applications. The key concepts, prevalent applications, and noteworthy ethical ramifications of each topic are analysed in detail. We conclude that integrating blockchain technology into people operations procedures can generally lead to a more moral workplace. This study gives us a sneak peek at how blockchain technology might be used to improve people operations processes at the intraorganizational, outboarding, and entry phases of an enterprise. The ethical implications are discussed in length from contractarianism, deontology, utilitarianism, and virtue ethics points of view. We believe that this study will help practitioners and academics alike become more conscious of and knowledgeable about the moral dilemmas raised by blockchain technology. We hope that our research will stimulate more thorough understanding of blockchain ethics among experts, academics, corporate leaders, and legislators. Moreover, our intention is that this study serves as an initial framework for further blockchain ethics research.

8 Blockchain Disruption in Finance Navigating the New Paradigm of Global Financial Systems

Pooja Darda, Anmol Singh Gandhi, and Shweta Yadav

DOI: 10.1201/9781032654812-8

8.1 INTRODUCTION

The financial sector is currently on the verge of a significant transformation driven by the use of blockchain technology. This ground-breaking technology, which serves as the foundation for digital currencies like Bitcoin, presents an unalterable record and decentralized structure, holding the potential to change the concept of trust within financial transactions. The technology has the potential to disrupt the industry by potentially reducing expenses, optimizing operational effectiveness, and promoting transparency. With the start of the 21st century, many new tools have become available that have had significant effects in many areas. The internet has made it easier for social media platforms to grow rapidly. These platforms create a seamless connection between billions of people and many businesses, encouraging regular and consistent contact [1]. The sharing economy has made good use of resources that are not used to their full potential. Companies that work in financial technology (fintech) often play a key role in achieving this goal. Because of this phenomenon, businesses that were not as competitive before have become fiercer. The emergence of blockchain has disrupted many industries, from banking and cybersecurity to supply chains and healthcare, simultaneously impacting the finance sector at the same time [2]. Financial regulators and the world need blockchains because they represent an opportunity for humanity to make a significant leap in how we understand the world in which we live. Value creation always has the power to disrupt traditional businesses regardless of the sector to which they belong. The introduction of block-chain has impacted many areas of trade finance, the securities market, decentralized finance, achieving effectiveness and cost efficiency, the public financial sector, and enabling KYC know your customer) and anti-money laundering [3]. The development of blockchain technology is a significant step forward in the field of data storage and information transfer. It is important not to underestimate how this new idea could completely change how the financial industry and the economy work as a whole [4]. This transformative ability has the potential to bring about a new wave of technological innovations and changes in the fintech industry’s work environment. “Necessity is the mother of invention,” and the development of blockchain has gotten a lot of attention as an innovative tool that could change the way money works [5]. A significant change has occurred with the rise of this paradigm, which could have a significant effect on the future of the financial industry.

Blockchain is usually thought of as a reliable and openly available distributed ledger [5]. According to a study published by The Economist in 2015, the system works in a decentralized network structure, which means that power is held not by a single entity but by many participants. A decentralized record system can be easily set up with the help of these features [6]. Many people think of blockchain as a public record because it can be viewed by everyone who needs to see it [5]. Information in blockchains can naturally resist changes made by people who are not supposed to [5]. This makes the blockchain a more reliable and trustworthy record. These features enable blockchain technology to successfully facilitate the transmission of information in a decentralized manner, thereby eliminating the need for intermediaries.

This study will help us understand the principal need for blockchain in the smooth operation of the securities market, reducing intermediaries in the market, and facilitating fund transfers in the finance sector. The chapter also examines the impact of blockchain on the tokenization of assets and mitigation of risk in the finance world through the use of blockchain.

The chapter also discusses blockchain-based financial service decentralized finance (DeFi), which aims to eliminate the role of intermediaries and provide open and smooth financial services. The current state of the adoption and integration of blockchain technology into conventional financial institutions is still in its early stages, despite its considerable promise. The objective of this study is to conduct a comprehensive analysis of the present status of blockchain applications in the financial sector. This will be achieved by utilizing a wide range of secondary data sources to consolidate existing information and discern recurring trends in the implementation, advantages, and obstacles associated with blockchain technology.

The study will commence by doing a comprehensive literature analysis to identify the fundamental principles of blockchain technology and its theoretical implications in the field of finance. Subsequently, a thematic analysis will be conducted utilizing a desk research approach to identify and examine the prominent topics derived from secondary databases, encompassing academic publications, industry reports, and case studies. The subsequent discourse will merge these discoveries to unveil the broader ramifications of incorporating blockchain technology into the realm of financial services. In conclusion, this article will finish by providing a reflective analysis of the research gaps that have been found, as well as discussing the aims of the present study and suggesting prospective directions for future research.

Although there exists a growing collection of scholarly work on the subject of blockchain technology, a discernible deficiency can be observed in terms of empirical investigations that comprehensively synthesize the many uses of blockchain within the financial industry. Furthermore, a scarcity exists in terms of comprehensive thematic analysis that effectively synthesizes various research findings to offer a comprehensive perspective on the benefits and obstacles associated with the application of technology in the field of finance. Furthermore, the existing body of research frequently fails to provide a comprehensive analysis of the wider ramifications associated with blockchain technology. This includes its influence on regulatory adherence, the stability of markets, and the overall global financial environment.

The current state of the adoption and integration of blockchain technology into conventional financial institutions is still in its early stages, despite its considerable promise. The objective of this study is to conduct a comprehensive analysis of the present status of blockchain applications in the financial sector.

Khan & Syed, 2019

8.3 THEORETICAL FRAMEWORK

The resource-based view (RBV) is a theoretical framework that posits resources as critical determinants of achieving outstanding organizational performance. When a resource possesses traits that are deemed VRIO (valuable, rare, inimitable, and organized), it empowers the organization to acquire and maintain a competitive advantage [7]. The resource-based view (RBV) theory posits that resources are heterogeneous and immobile among different enterprises. The term “heterogeneous” refers to the condition in which many organizations possess distinct combinations of resources, resulting in diverse competencies and competitive advantages [8] The term “immobile” refers to the condition in which resources exhibit limited transferability or replicability among enterprises, primarily because of diverse isolating factors.

The integration of artificial intelligence (AI) applications within the financial industry may be seen as a valuable resource that has the potential to confer a competitive edge to organizations that use them [9]. The utilization of AI applications might prove to be advantageous in the context of business organizations, provided they contribute to the creation of value for consumers or the reduction of expenses. A scarcity of AI applications may arise when they lack widespread availability or accessibility to other organizations. AI applications possess the potential to be inimitable when they exhibit characteristics that render them arduous or expensive to replicate or replace them with alternative entities [10]. The organization of AI applications can be facilitated by the presence of complementary resources and competencies within the enterprise.

8.4 RESEARCH METHODOLOGY

A qualitative methodology was created, employed, and executed for this study, and content analysis was the method of choice for its implementation (Downe, 1992). We look at articles from newspapers and blogs, as well as annual reports from financial institutions, to learn more about AI in the financial industry. This study aims to explore 50 newspaper articles and blogs, in addition to 20 finance reports, all of which were published between September 2018 and October 2023, to identify recurring topics, benefits, and challenges associated with the application of artificial intelligence in finance. This study adheres to a six-step procedure and uses a thematic analysis technique to analyse all of the obtained digital information, including newspapers, blogs, and financial reports. This methodology is similar to that developed by Braun and Clarke (2006). In the beginning, you become acquainted with the information acquired from the interviews with the focus groups. The next step was the construction of the preliminary codes [11], The third stage was to identify the developing themes. Reexamination of the topics constitutes the fourth phase of the process. The formation of clear themes is the objective of the fifth stage, while the repetition of the findings and meticulous documentation of those outcomes is the focus of the sixth step.

To identify the many topics and their interrelationships, the data was manually labelled and categorized. This process was performed manually. Words and phrases acted as indicators of key themes. The investigation used framework was known as flat coding [12]. The current investigation utilized a paradigm known as flat coding, in which all codes in the database were assigned the same degrees of specificity and importance regardless of the context in which they were found. The current investigation reveals that code frames provide a high degree of adaptability, enabling researchers to successfully utilize their results in a variety of situations. This is demonstrated by the fact that code frames were used in the current investigation [13]. During the process of developing the codes, the researchers ensured that the codes covered a wide variety of answers, displayed opposing traits, and maintained a harmonious equilibrium between having too much data and not having enough.

8.5 FINDINGS AND DISCUSSION

8.5.1 THEME 1: BLOCKCHAIN TRANSFORMATION IN FINANCIAL MARKETS

The main point of this theme is how blockchain technology has changed the world of financial markets in profound and new ways. The use of blockchain technology has the potential to completely change and rearrange many aspects of the financial market universe [14]. This transformative possibility shows up as more efficient operations, more openness, and new growth and development opportunities. Our study has shown that there are eleven subthemes within the main theme. The first set of subthemes are as follows:

Subtheme 1.1. Securities Market Realignment: The main idea of this subtheme is that blockchain technology has the potential to change the way the stock market works [15]. More attention is paid to the idea of a private stock exchange, which shows how blockchain technology could be used to create new markets for shares.

Subtheme 1.2. Blockchain Potential: What makes blockchain technology so useful is that it can automatically create a decentralized and open record system. This one-of-a-kind trait shows a lot of promise because it could have a big effect on trading and managing different investments [15]. The technology has the built-in ability to keep a reliable and permanent record of who owns what and what activities have happened.

Subtheme 1.3. Private Stock Exchanges: In this subtheme, the idea of private stock markets is explored. These could be about stock markets that aren’t open to the public yet but use blockchain technology to work [16]. Specific types of stocks or investors may benefit from more freedom when trading on private stock exchanges because they have their own set of rules and laws.

Subtheme 1.4. Realignment: The word “realignment” refers to a big change in how the stock markets work. By using blockchain technology, trading processes, settlement systems, and legal compliance could all be made better [17]. This is because blockchain technology is very efficient and clear.

Subtheme 1.5. Potential Benefits: This subtheme suggests that adding blockchain technology to the stock market could have many positive effects [18]. Among these benefits are shorter settlement times, lower operating costs, and easier access for a wider group of investors.

Subtheme 1.6. Reduced Intermediation: The current subtheme focuses on exploring the implications of blockchain technology in reducing the reliance on intermediaries within the realm of financial transactions [19]. This statement highlights the potential benefits that can be derived from the reduction of intermediation, such as improved efficiency and reliability.

Subtheme 1.7. Intermediaries: When talking about financial deals, intermediaries are groups that act as third parties or play a role between two parties. Institutions like banks, traders, and clearinghouses are examples of these groups [20]. Cryptocurrencies naturally can make deals easier and more secure, but they come with extra costs and complexity.

Subtheme 1.8. Blockchain’s Role: Implementing blockchain technology could make transactions more efficient by providing a safe and open space for people to connect [14]. Once this technology is put into use, it might not be necessary to have as many standard intermediaries.

Subtheme 1.9. Increased Efficiency: Lessening the role of intermediaries may help improve the speed of financial transactions. It’s well-known that adding blockchain technology to many different fields could be very helpful. Blockchain can streamline settlement processes by using its automated functions and smart contracts, which can lead to faster transaction handling [21]. Furthermore, the decentralized and open ledger system of blockchain makes mistakes and delays less likely, which improves general efficiency and dependability.

Subtheme 1.10. Reliability: The main idea is that you might be able to make financial deals more reliable by cutting down on the participation of intermediaries [17]. Using a distributed ledger in blockchain interactions makes them more resistant to fraud, manipulation, and data loss.

Subtheme 1.11. Cost Reduction: Cutting down on the number of intermediaries could lower costs because it lowers the fees and commissions that come with working with them [22].

8.5.2 THEME 2: DECENTRALIZED FINANCE (DEFI) REVOLUTION

The central theme of this discussion centers on the transformative growth and impact of decentralized finance (DeFi), a movement that seeks to establish a financial system built entirely on computer programming, thus eliminating the need for intermediaries.

Subtheme 2.1. DeFi Growth: The principal aim of this study is to analyze the swift proliferation of the decentralized finance (DeFi) movement [23]. Decentralized finance represents a notable paradigm shift in the financial sector, whereby traditional intermediaries like banks and brokers are replaced by the utilization of smart contracts and blockchain technology.

Subtheme 2.2. Decentralization: Decentralized finance is a way of thinking about money that uses blockchain technology and smart contracts [24]. The use of these technology tools by DeFi creates a decentralized system that allows for direct financial transactions between individuals. No decentralized systems or intermediaries are present.

Subtheme 2.3. Code-Based System: Code-based financial infrastructure is what decentralized finance is based on. Smart contracts run a lot of different financial tasks automatically, like loans, borrowing, trading, and managing assets [25]. After certain conditions have been met, these contracts are carried out automatically

Subtheme 2.3. Growth: The subtheme talks about how the DeFi movement has grown a lot in recent years, showing that it has a lot of support [26]. The overall worth of assets that are currently locked within DeFi protocols has gone up by a large amount, as seen in the decentralized finance ecosystem.

Subtheme 2.4. Disruption: Traditional financial companies are having a hard time with the rise of decentralized finance (DeFi). With the arrival of this new idea come decentralized options that could question the traditional role of banks and other financial institutions [27]. The options just listed are different in several ways, including being naturally open, not requiring permission, and being accessible to anyone with internet access.

Subtheme 2.5. Lower Transaction Cost: DeFi systems often demonstrate a propensity for reduced transaction fees when compared to traditional financial systems [28]. The implementation of this solution has the potential to significantly improve cost efficiency for individuals seeking to engage in various activities, including but not limited to trading, lending, and borrowing.

Subtheme 2.6. Diversification Opportunities: Many types of financial services and goods run on decentralized platforms. These are all called decentralized finance (DeFi). People who do a lot of different things, like yield farming, liquidity provision, asset dealing, and other similar activities, can vary significantly increase the diversification of their investment portfolios [29]. As a strategy, diversification has the potential to successfully lower risk and possibly improve the results of investments.

Subtheme 2.7. Higher Interest Rates: Several DeFi protocols present enticing interest rates for assets that are deposited, enabling users to generate passive income through participation in lending or liquidity-providing activities [30].

Subtheme 2.8. Accessibility: DeFi systems are unique because they can be easily accessed by anyone with an internet link. This makes financial inclusion a reality for more people [31]. The DeFi ecosystem’s accessibility makes it easier for people from all over the world to join, allowing for global involvement.

Challenges: A lot of people are interested in decentralized finance because it has a lot of benefits. But it’s important to remember that this new and innovative financial environment comes with some problems and risks. Some of these are security holes, worries about how smart contracts work, and unclear rules about how they should be used [28]. To keep the DeFi space stable and open in the long term, it is important to carefully look at and deal with these possible risks and problems. People who are interested in decentralized finance (DeFi) should be very careful and do a lot of research before entering into any transactions.

8.5.3 THEME 3: BLOCKCHAIN’S IMPACT ON RISK MANAGEMENT AND TRANSPARENCY

The primary subject matter of this discussion pertains to the ramifications of block-chain technology on risk mitigation and the enhancement of transparency within the financial sector. The intrinsic characteristics of blockchain technology, namely immutability and transparency, play a crucial role in mitigating risks and improving transparency.

Subtheme 3.1. Immutability: The fact that blockchain can’t be changed is a key feature that shows how permanent data is by its very nature. It is impossible to change or delete information that has already been added to the blockchain [32]. This trait makes sure that financial records are reliable and of high quality for a long time.

Subtheme 3.2. Transparency: Blockchain technology presents a transparent and auditable ledger system, wherein the visibility of all transactions is readily accessible to users with authorized access privileges [33]. The application of transparency has been found to have the potential to enhance the efficiency of monitoring and validating financial transactions.

Subtheme 3.3. Risk mitigation: The immutability and openness of blockchain technology are two of the most important ways by which blockchain lowers the risks of fraud, data theft, and mistakes in financial records [34]. The worries we talked about earlier are successfully dealt with because blockchain records have strong security measures and can’t be changed.

Subtheme 3.4. Regulatory Compliance: Blockchain technology’s built-in features of transparency and traceability show a lot of promise for helping financial companies do what they need to do to meet regulatory requirements. This is made possible by keeping a full record of all transactions, which can then be used for checks.

Subtheme 3.5. Smart Contracts: Smart contracts have the unique ability to execute themselves and follow rules that have already been set. This means that they can be used to automate and improve risk management processes. These contracts can be set to run immediately once certain conditions are met. This makes it less likely that mistakes will happen when people are involved.

Subtheme 3.6. Counterparty Risk: Counterparty risk, which is also called default risk, is a natural risk that comes from the fact that one party to a financial transaction might not keep its end of the deal. Implementing blockchain technology is a hopeful way to lower this risk because it makes it easier for contracts to be automatically carried out and enforced.

Subtheme 3.7. Cost Reduction: One big benefit of using blockchain technology is that it lets important parties do business directly with each other, which could cut down on the costs of intermediaries [35]. Because of what has been seen, costs are going down, and maybe even the efficiency of banking processes is going up.

Subtheme 3.8. Efficiency: The decentralized and very efficient way that trades are handled on a blockchain is what makes it unique [36]. This behavior might make it easier to settle quickly and reduce the number of delays that happen, which would help lower counterparty risk.

Subtheme 3.9. Transparency: The use of blockchain technology provides a strong and safe way to keep a public ledger that can’t be changed. This makes sure that everyone has the same chance to get correct and consistent knowledge [37]. That there is openness in a certain situation makes people more likely to trust each other, which makes it less likely that conflicts will happen.

Subtheme 3.10. Regulatory Benefits: One way that blockchain technology could make it easier for people to follow the rules is by giving officials quick access to information about transactions [34]. This function makes it easier to keep an eye on and manage financial transactions and activities.

Subtheme 3.11. Trust Enhancement: Implementing blockchain technology has the built-in ability to reduce counterparty risk, which leads to more trust between the different parties involved in financial transactions [38]. This fact makes it possible for transactions to go smoothly without the need for intermediaries.

8.5.4 THEME 4: EFFICIENCY, SECURITY, AND PRIVACY IN FINANCIAL SERVICES

The main point of this case is how blockchain technology improves the speed, safety, and privacy of banking services in many different ways [39]. The goal of this study is to look into how blockchain technology could be used to improve operational efficiency, cut costs, and protect data privacy and security in the financial industry (Figure 8.2).

FIGURE 8.2 Thematic model for blockchain in finance.

Subtheme 4.1. Efficiency comparison: People often draw comparisons between blockchain technology and older technologies used in the financial sector to show how blockchain could be used to make operations more efficient, transaction times shorter, and many financial tasks automated [39].

Subtheme 4.2. Transition discussion: This subtheme looks into the complicated process of switching from old, traditional systems to new, innovative blockchain-based ones [40]. Many things need to be looked at in this study in order to fully understand the pros and cons of using blockchain technology in banking services.

Subtheme 4.3. Operational Benefits: The utilization of blockchain technology holds promising prospects for enhancing the efficacy of financial processes by leveraging several mechanisms, such as accelerated settlements, enhanced auditability, and augmented transparency [41].

Subtheme 4.4. Privacy Protection and Data Security: Homomorphic Encryption: Homomorphic encryption is a cryptographic technique that facilitates the manipulation of data while maintaining its confidentiality through encryption [42]. This method lets processes be run on encrypted data, which makes sure that data privacy is maintained throughout the whole processing stage. Combining blockchain technology with homomorphic encryption looks like a good way to make security steps for financial data and transactions significantly stronger. The integration that is being thought about will effectively stop unauthorized access and protect the integrity of data, which will make the overall security procedures stronger.

Subtheme 4.5. Fraud Prevention: The application of sophisticated encryption techniques has demonstrated a notable decrease in the probability of fraudulent actions and unlawful entry, thereby offering a safeguard for financial assets and confidential data [43].

8.6 IMPLICATIONS

8.6.1 MANAGERIAL IMPLICATIONS

To get the most out of blockchain technology in the financial sector, financial managers must make it a top goal to make sure that all departments work together and communicate clearly. Getting everyone on the same page about the problems that areas like investment, risk management, and compliance are having is very important. Financial managers could make better use of blockchain technology to better coordinate their efforts and encourage teams to work together in sync, which would help their organizations reach their goals more quickly.

Also, it’s the job of finance managers to make sure that money is set aside for training staff. The most important thing is to consistently use the information and skills you’ve gained through training. Committing to ongoing education is very important if you want to make smart financial decisions, reduce risks, and follow the rules that are always changing.

8.6.2 THEORETICAL IMPLICATIONS

The planned use of blockchain technology in the financial sector is expected to significantly change how businesses run by making them more flexible and quicker to respond to new situations. It is very important to make the necessary changes to traditional financial theories so that they properly understand and account for the financial system’s inherent flexibility. On the other hand, the system always seems to be able to change in reaction to a lot of different internal and external factors. Specifically, the use of blockchain technology is a key factor in changing how financial operations and activities work and how they change over time.

It is possible that the theoretical implications of blockchain technology could help the financial industry in big ways. Some of these effects are decentralization, security, smart contracts, lower costs, faster settlement, better identity verification and know-your-customer (KYC) processes, cross-border transactions, more people having access to money, data privacy and ownership, and tokenizing assets.

Using blockchain technology has many benefits, such as getting rid of intermediaries, lowering transaction costs, lowering the risk of fraud, and making more people able to access banking services. Utilizing blockchain technology makes it possible to create a public ledger system that successfully ensures the recording and confirmation of transactions. As a result, this approach greatly lowers the chance of fraud. As it stands, smart contracts can automatically carry out a number of tasks, which makes operations more efficient in areas like loan origination, settlement, and trade completion.

It also speeds up settlement, makes managing identities easier, and allows for quick settlement. However, using blockchain technology also comes with a set of governing issues, such as worries about security, fraud, taxes, and following the law. Even with these problems, blockchain technology’s ability to be open and trackable could improve risk management by giving accurate information and reducing mistakes, scams, and data security breaches. In order to get the most out of these benefits, they must be put into practice, and regulations must be changed.

8.6.3 POLICY IMPLICATIONS

The policy implications cover a number of important areas, including the creation of clear regulatory frameworks, the protection of data privacy and security, the recognition of smart contracts as legally binding documents, the tokenization of assets, the enforcement of strict anti-money laundering and know-your-customer laws, the creation of international standards for cross-border transactions, and the support of financial inclusion. The most important thing for policymakers to do is work together with experts in the field and other interested parties to create a complete regulatory system. This system should not only encourage new ideas but also protect financial stability and safety. Policymakers need to have a deep knowledge of blockchain technology and the risks that come with it in order to create rules that encourage innovation while also protecting financial stability and security.

Within the financial industry, which operates within a dynamic technological landscape, it is imperative that regulatory frameworks governing this domain exhibit a notable level of flexibility and adaptability. This stands in contrast to an inflexible and unwavering approach that resists change. To optimize the efficacy of policymaking within the financial sector, it is recommended that policymakers embrace an iterative approach. The most important thing about this project is that it can constantly improve and tweak policies by setting up a feedback loop with the financial system.

By actively involving and integrating a wide range of stakeholders in the financial sector, lawmakers can make sure that their policies are flexible and responsive enough to meet the changing and unpredictable needs of businesses. Using a method based on blockchain technology helps lawmakers make smart choices based on upto-date information and useful insights. The decentralized and unchangeable record of blockchain technology could be used in a lot of different ways. This could make the iterative process of making policies even better.

8.7 LIMITATION

The research approach utilized in this study mostly entailed the exploitation of secondary data sources. The conscious decision was made in order to provide a strong foundation for the investigation within the current body of literature and proven research findings. The technique utilized enabled the acquisition of a thorough understanding of the current status of artificial intelligence (AI) in the field of finance. The possible integration of primary data into future research activities has the capacity to offer innovative and unique insights and viewpoints.

8.8 CONCLUSION

As blockchain technology can fix problems that have been around for a long time, it’s easy to see how it could change the finance world. People think that using blockchain technology in the financial sector could have a number of benefits, such as making transactions faster and clearer for clients. This technology has the potential to get rid of the need for intermediaries, which would save money for financial institutions [44]. Deploying this technology has the potential to make bank credit information and payment clearing systems more effective and protect their integrity. Researchers have found that blockchain technologies make it possible to make decentralized settings with few intermediaries. This trait has the potential to make financial businesses run more smoothly. In the current situation, it is easy to see that regulatory, economic, and security problems will not go away [45]. A thorough look at past data, however, shows that concerted efforts are likely to be made to deal with these problems. Because of this, blockchain technology will likely soon be used at full capacity in the financial industry. Blockchain technology is a promising idea that has the potential to solve problems and change the way money is handled.

8.9 FUTURE SCOPE

Blockchain integration is a beacon of financial technology change. Future research in this field is extensive and promising. Globalizing the study to encompass several financial ecosystems would show blockchain’s flexibility and efficacy across regulatory and economic contexts.

Another important area of study is regulatory framework evolution. How block-chain’s disruptive nature is accepted will determine its adoption rate and breadth. This supports studying technical advances that promise improved scalability and security, which are crucial to the technology’s development and acceptability.

Fraud prevention and cybersecurity warrant more study. Immutable recordkeeping in blockchain might redefine financial transaction trust, reducing fraud and improving security. Decentralized finance (DeFi) is also a promising study area, notably its potential synergy with the banking industry and regulatory discussions.

Another frontier is asset tokenization, which might change financial market liquidity and ownership. Smart contracts’ self-execution might expedite many financial operations, both legally and practically. Blockchain has a huge influence on financial inclusion. Blockchain might democratize financial services in underbanked areas, promoting socioeconomic fairness. The efficiency of blockchain-enabled cross-border transactions might also revolutionize international trade and remittances. Data privacy, a big topic after GDPR (General Data Protection Regulation), is another important study subject. How blockchain protects personal financial data while meeting regulations is crucial. Quantitative methods would support qualitative findings and prove blockchain’s usefulness. We could track the technology’s uptake and long-term effects via longitudinal research.

Industry-specific impacts, consumer adoption patterns, the environmental footprint of blockchain operations, interoperability issues, central bank digital currencies, traditional financial intermediaries and job roles, financial stability, and crisis management are all research topics. These avenues might reveal blockchain’s many effects on the financial industry and its role in economic progress and innovation.

9.1 INTRODUCTION

9.1.1 CRYPTOGRAPHY ESSENTIALS

Two individuals or two organisations can communicate in private while keeping their identities hidden from outsiders by using encryption. Early in the year 1900 bce, hieroglyphics etched on stone in ancient Egypt had been concealed from individuals who did not know their meanings using an atypical cryptography. Atbash is one of the first Hebrew cyphers. Based on the ancient Kamasutra of Vatsyayana, two distinct types of ciphers were being used in ancient India: Kauitiliyam and Mulavediya. The Kautiliyam cypher was developed using phonetic linking, such as substituting vowel and consonants. Employing a pair of characters and its reciprocals, the Mulavediya cypher developed [1]. According to Muslim writer Ibn al-Nadim, two secret scripts were used in Persia during the Sasanian era: Official letters made use of sah-dabiriya and secret messages with foreign nations was done using raz-sahariya.

The Playfair Cipher, invented by Charles Wheatstone in 1854, encodes pairs of letters rather than isolated ones, making it harder to crack.

The Father of Western Cryptology, Battista, acquired notoriety for developing substitution using polyalphabetic characters. His method consisted of interconnecting two copper discs. On each of them was imprinted the alphabet. In order to prevent frequency analysis from being used to break the cipher, the discs were spun to vary the encryption mechanism every few words [4].

Rubin asserts that Vigenère had nothing to do with the invention of polyalphabetic substitution, despite the fact that it underwent a number of alterations and is most often credited to him. Rubin also notes that, throughout the Civil War, the South continued to utilise brass cypher discs, despite the fact that the North frequently deciphered communications (the Roman Caesar Shift Cypher). It made use of the concept of changing letters by a predefined number, three historically, and producing the message using this letter-shifting technique [5].

Nowadays, the public key cryptography approach is employed. Today, asymmetric encryption is used with a shared common key and a private key that is exclusively held by the sender. In this situation, the sender encodes the message using the private key, and the recipient decodes it utilising the public key.

In 1917, American engineer Edward Hebern constructed an electromechanical device that had an oscillating disc embedded in the key. This is the first instance of a rotor machine using an adaptive substitution table that changes whenever a new character is entered for encoding. The Enigma machine, constructed in 1918 by German engineer Arthur Scherbius, is a commercial invention that employs many rotors as opposed to just one rotor used in Hebern’s device. The German military started using it to transmit codes after learning its power.

Gilbert Vernam attempted to reinforce the broken cypher and developed the Vernam–Vigenère cipher in 1918, but he was unable to produce one that was noticeably stronger. His efforts resulted in the creation of the one-time pad, which employs a key phrase just once and has been shown to be nearly indestructible (Rubin, 2008).

9.1.1.1 Frequency Analysis

Frequency analysis, a technique for cracking replacement cyphers by examining a language’s letter frequency, was created by Arab academics in the 9th century. As a result, monoalphabetic cyphers’ security was greatly compromised.

In the 16th century, the Vigenère cipher was invented, introducing the concept of using a keyword to change the substitution alphabet. This made it more challenging to break the cipher using frequency analysis. Blaise de Vigenère, a French diplomat, made important contributions to the study of cryptography. He published a treatise on cryptanalysis, helping to advance the field. During the 18th century, significant developments included the creation of more complex ciphers, such as the Jefferson disk cipher, which used rotating disks to encipher and decipher messages.

The German military adopted and employed the Enigma machine in the 20th century, especially during World War II. Messages were encrypted using a sophisticated mechanical system. Alan Turing and other Allied cryptanalysts made a critical breakthrough when they cracked the Enigma cypher.

9.1.1.2 Data Encryption Standard (DES)

DES was developed by NIST (National Institute of Standards and Technology) in the 1970s. It is a symmetric-key encryption standard that is still in use today. From it, the Advanced Encryption Standard (AES) was subsequently developed.

Public-key cryptography is now a must for safe online communication and e-commerce because it enables secure key exchange without the need for a previously known shared secret. With the development of algorithms like RSA and Diffie–Hellman, public-key cryptography revolutionised secure communication.

Elliptic curve cryptography (ECC) is a state-of-the-art encryption technique that has gained popularity because it offers great security with comparatively tiny key sizes, making it appropriate for devices with limited resources. With the development of quantum computers, post-quantum cryptography, which strives to provide encryption techniques that are impervious to quantum assaults, has gained increasing attention. The decentralisation and transaction security of cryptocurrencies like Bitcoin and Ethereum are provided by cryptographic techniques.

9.1.2 CRYPTOGRAPHIC BUILDING BLOCKS

Two essential methods for protecting data and communications in the realm of cryptography are symmetric and asymmetric encryption. They employ several methods for key management, data encryption, and decryption. Symmetric encryption employs the same secret key for encryption and decoding. Anyone participating in the communication must exchange and protect this key in an encrypted manner.

9.1.2.1 The Algorithm

The algorithm and key used for both encryption and decryption are the same. Symmetric encryption is usually faster and more efficient than asymmetric encryption since it requires fewer computing processes.

When encrypting data that is at rest, such as files and databases, symmetric encryption is frequently utilised. Once a first secure connection has been made, it is also used to encrypt data in transit, such as secure communication over the internet. It is also used for encrypting data in transit, like secure communication over the internet, once an initial secure channel has been established.

Symmetric encryption is extensively used for the encryption of information that is at rest, like files and databases. It may also be used to encrypt data while it’s in transit, like secure internet communication, once the first secure connection has been established. Once a secure channel has been created, it may also be used to encrypt data while it is in transit, such as during secure internet communication. For example, AES is a frequently used symmetric encryption method.

9.1.2.2 Public-Key Encryption, or Asymmetric Encryption

Asymmetric encryption involves two keys: a private key and a public key. The public key is used for encryption, and the private key must be obtained for decryption. While there is an abstract connection between the public and private keys, executing is computationally difficult.

With respect to security, because the private key is kept hidden and the public key is made available to everyone, asymmetric encryption is very secure.

Asymmetric encryption is frequently utilised for the exchange of keys and digital signatures. It is a crucial part of secure communication protocols like email encryption and HTTPS (secure web surfing). Example are the RSA and Elliptic Curve Cryptography (ECC), which are common asymmetric encryption algorithms.

In conclusion, symmetric encryption works well in situations when you have an accurate means to share keys, but it also requires efficient key distribution. Asymmetric encryption is slower and necessitates more processing resources than symmetric encryption; still it circumvents the key distribution problem through the utilisation of public and private key pairs, making it ideal for electronic signatures and secure communications. Hybrid encryption is a blend of symmetric and asymmetric encryption in secure systems to provide security and efficiency.

9.2 BLOCKCHAIN

9.2.1 UNDERSTANDING BLOCKCHAIN

Blockchain, as the name suggests, is a distributed, decentralised digital ledger that stores transactions via a network of computers in an unbreakable, secure manner. It is the technology behind Bitcoin as well as other cryptocurrencies, but its applications go beyond virtual money. The basic elements of a blockchain are discussed next.

9.2.1.1 Blocks

Blocks are the essential units of data in a blockchain. Every block consists of a group of operations or data elements. This block and the one before it are cryptographically linked, creating a chain of blocks that goes by the name “blockchain.”

9.2.1.2 Structure

The following sections typically make up a typical block:

Transaction data refers to the actual information—that is, the transactions—that are being stored on the blockchain.

The primary components of a blockchain are:

9.2.1.3 Blocks

Blocks represent the fundamental components of information within a blockchain architecture. Each block is comprised of a collection of transactions or data entities. This particular block, along with its predecessor, is interconnected through cryptographic methods, thereby forming a sequential linkage of blocks.

9.2.1.4 Miners

Miners, depending on the consensus method used, are participants in the blockchain network who compete to solve difficult mathematical challenges through a technique known as proof-of-work (also known as PoW) or proof-of-stake (PoS). Tokens of cryptocurrency, like Bitcoin, are offered to miners as reward for their efforts.

9.2.1.5 Functions

Miners authenticate and add new blocks to a PoW-based blockchain by resolving computationally hard problems.

Validators are chosen to generate new blocks in a proof-of-stake (PoS) blockchain based on the amount of bitcoin they hold and their willingness to offer “stake” as collateral. Together, these vital components build a transparent and secure distributed ledger system. Broadcast to the network, miners (in PoW-based systems) append the transactions to a block, where they undergo verification by nodes. When data is put to the blockchain, it becomes very difficult to modify it while ensuring data integrity and system trust. Beyond cryptocurrency, supply chain management, voting structures, and other fields where the integrity and transparency are crucial uses for blockchain technology.

9.2.2 BLOCKCHAIN MECHANICS

Depending on the particular blockchain network, a combination of processes and protocols are used by blockchain to accomplish consensus and transaction validation. Proof-of-work and proof-of-stake, two widely used consensus procedures, are critical for ensuring that transactions are correctly examined and added to the blockchain. Blockchain enables consensus and transaction validation in the following ways.

9.2.2.1 Proof-of-Work (PoW)

The goal of miners on PoW-based blockchains, such as Bitcoin, is to solve challenging computation problems.

Miners aggregate ongoing transactions and group them into blocks.

To add a single transaction to the blockchain, a miner needs to find a nonce, which is a random number that, when hashed with the data in the block, creates a hash value that meets certain criteria (such as starting with an appropriate amount of leading zeros). It takes a lot of work to find this nonce, and that process is known as mining.

The new block is broadcast to the network by the first miner to discover a valid nonce, after which other nodes confirm its authenticity.

The block is uploaded to the blockchain when it has been confirmed, and the miner is compensated with bitcoin tokens.

By adding new blocks that are computationally costly and require miners to commit resources, PoW ensures that malevolent actors cannot easily influence the system.

9.2.2.2 Proof-of-Stake (PoS)

In PoS blockchains like Ethereum 2.0, the value of bitcoin that validators, also called forgers, hold and have ready to “stake” as collateral, Ethereum chooses who gets to generate new blocks initially.

In a deterministic process, validators are chosen to build blocks, frequently taking into account their stake in bitcoin and the age of their holdings.

Blocks are created and validated by validators without the resource-intensive calculations necessary in PoW.

Because they have an economic interest in the network, validators are motivated to behave honestly. They run the danger of forfeiting their staked assets if they approve fraudulent transactions.

PoS is thought to be more energy-efficient than PoW, but it necessitates that validators have a stake in the security of the network.

9.2.2.2.1 Transaction Validation

A fresh block that has been successfully created by a miner (or validator) includes a group of transactions.

These transactions are confirmed by network nodes before being added to the blockchain. The following tests are often included in validation:

Electronic signatures confirm that the public keys of the parties involved are the same and that the transaction signatures are legitimate.

Checking for double spending ensures that the sender has enough money to pay the transaction and that the same money has not already been used for another transaction.

For consistency, that the transaction follows the guidelines and regulations of the blockchain must be verified.

A transaction is deemed genuine and put to the block if it successfully passes all validation procedures.

In conclusion, consensus algorithms such as PoW and PoS ensure that network users concur on the order.

9.2.3 TYPES OF BLOCKCHAINS

A blockchain is made out of blocks, which are a growing collection of records. These blocks are linked via cryptography, and each block has the encryption hash of its predecessor. A blockchain is designed to make data alteration difficult. It functions as an open distributer ledger that may effectively record transactions between two parties. Once data has been captured, it cannot be changed back without altering all the relevant blocks. The double-spending issue was resolved with the invention of the blockchain for bitcoin, making it the first digital money to operate without an actual central server.

A pair of blockchain types exist: blockchains that are either permissioned or private and those that are permissionless or open.

An open network with no permissions has the primary benefit of having no need for any kind of access control or protection against attackers. This indicates that adding apps to the network is possible without obtaining anybody else’s permission or authority.

The fundamental benefit of an open, permissionless network is that access management and protection against malicious actors are not required. This indicates that adding apps to the network is possible without asking for or receiving permission from others.

Permissioned blockchains employ an access control layer to monitor who has access to the network. On private blockchain networks, as opposed to public block-chain networks, network owners assess the validators. They don’t rely on unidentified nodes to ratify transactions. The fundamental drawback of this type of blockchain is that, if the blockchain generation tools on a private corporate server were to be destroyed, the network might effectively be under complete control.

Traditional databases and blockchain databases vary mostly in that:

The client–server network design uses traditional databases. This allows data to be changed by a user or client and then kept on a centrally located server. The database is under specified authority administration. Since this authority is in charge of database regulation, data can be modified or eliminated if the authority’s credibility is called into question.

Blockchain databases had been using a variety of independent nodes. Every node participates in management. The majority of nodes have to collaborate for any addition to be made on the blockchain. This collaborative technique guarantees the network’s security.

The listing of various key blockchain platforms are discussed next.

9.2.3.1 Bitcoin

The world became exposed to the blockchain technology and platform through Bitcoin, the first widely acknowledged and applied distributed cryptocurrency [5]. Bitcoin runs a peer-to-peer network without a central authority or banks. Together, the blockchain network manages funds issuance and handling transactions. To validate transactions, Bitcoin uses the energy-intensive PoW consensus mechanism. The rise in popularity of Bitcoin prompted the creation of different cryptocurrencies and consensus methods, all of which are included in the investigation that follows. The essential components of a Bitcoin transaction address are the wallet software, the private key, and Bitcoin software [6]. It is virtual rather than traditional; neither actual nor digital money is administered.

Participants use their keys to unlock and sign transactions. Transferring it to a new key holder consumes its value. Keys on user terminals are frequently stored in a digital wallet. Bitcoin is dependent on “mining,” a powerful mathematical technique that validates and executes transactions.

9.2.3.2 Ethereum

Anyone may create and utilise Smart-Contract-based, decentralised apps that utilise blockchain technology on the Ethereum platform. By supporting smart contracts or properties, Ethereum concentrates on the ability of automatic digital asset management, which makes the development of asset managing programmes simpler than when utilising the programming language in the Bitcoin Blockchain. Additionally, Ethereum uses the PoW consensus system.

9.2.3.3 Zcash

Zcash is an open-source, autonomous cryptocurrency that allows for transaction anonymity and privacy. A drawback with the Bitcoin Blockchain is that, even if senders and receivers can be determined by a hashed address, if sufficient transaction information is available, it is still possible to link or monitor specific transactions with meticulous study and analysis.

9.2.3.4 Litecoin

A distributed global payment network is Litecoin. The main difference between Litecoin and Bitcoin is that one of them offers four times faster transaction speeds but at the cost of four times less storage capacity and lesser security. Furthermore, Litecoin uses the Scrypt hash algorithm for proof-of-work as a means to solve the issue regarding mining centralisation.

9.2.3.5 Dash

Dash (also known as digital cash) is an instantaneous digital currency that prioritises anonymity. It is built on the Bitcoin software and extends the Bitcoin Blockchain network by adding a so-called Masternode network tier. The nodes that make up the Masternode network are ready to surrender their right to operate as full nodes and validate operations for “collateral,” like the 1000 DASH coins. The Masternode allows users to gain further privacy or obscurity via Darksend.

9.2.3.6 Coin Peercoin

As a successor of Bitcoin, Peercoin was developed to use less energy when mining coins. In other words, because the PoW algorithm of Bitcoin relies on energy consumption, miners will eventually become discouraged from adding new blocks until transaction fees rise to a point where the high energy consumption is offset. To avoid this situation, Peercoin proposed utilising proof-of-work (PoW) initially and then upgrading to proof-of-stake (PoS).

9.3 CRYPTOGRAPHY IN BLOCKCHAIN

9.3.1 ROLE OF CRYPTOGRAPHY

To guarantee the anonymity of data recorded on the blockchain, cryptography is necessary. It makes it possible to encrypt sensitive data, such as transactional information and user identities, rendering it unreadable without the proper decryption keys. On the blockchain, transactions and data integrity are confirmed using cryptographic digital signatures. In a blockchain network, every participant has separate privately and publicly accessible key pairs. The sender signs an exchange using their private key, which receivers may verify utilising the public key supplied by the sender. This ensures that transactions are authentic and unaffected.

A unique, fixed-length representation of the data is produced using cryptographic hash algorithms. Transactions are hashed and connected in blocks in blockchains.

Cryptography is vital for preventing double-spending attacks, which involve spending the same cryptocurrency tokens more than once. Blockchain networks improve system security and reliability by using cryptographic techniques to make sure that a transaction cannot be changed or spent again once it is added to the ledger.

Cryptography is the backbone of blockchain security. It ensures data privacy, data integrity, transaction authenticity, and overall protection against various security threats.

9.3.2 CRYPTOGRAPHIC TECHNIQUES

The foundation of blockchain technology is cryptography, which supports the three main tenets of decentralisation, security, and transparency. We will talk about the critical function that cryptography plays in blockchain ecosystems in this part. Since the blockchain is accessible to all users, it is crucial to safeguard the data there and keep user data safe from nefarious actors. Thus cryptography may be used to accomplish this with ease.

A transaction is added to the blockchain once it has been verified by a hashing algorithm. Subsequently, it is added to the network, forming the chain of blocks.

By using the combination of codes, cryptography makes sure that the data can only be retrieved by those who are supposed to read and process it.

Hashing cryptographically is one of the most significant uses of cryptography. Hashing provides blockchain immutability. When a transaction is confirmed, the hashing algorithm adds the hash to the block and creates a new, unique hash from the original transaction. Hashing continues to mix and generate new hashes, but the old trail is still readily available. The root hash is the output of combining one hash with a different one. A change made to any block’s data will cause the blockchain to collapse. Blocks are connected by the hash function, which also guarantees the accuracy of the data they contain. A couple more well-known hash algorithms are MD5 and SHA-1.1.

9.3.2.1 Data Integrity and Immutability

Cryptography is the shield of data integrity in a blockchain. The integrity of transactions and data is maintained when they are hashed (converted into fixed-length alphanumeric sequences) using cryptographic hash algorithms. No matter how little a change in the data, the hash will alter dramatically. It is extremely difficult for counterfeiters to alter previous transactions without being noticed thanks to this characteristic.

9.3.2.2 Transaction Authentication

A set of public and private keys that together form a cryptographic identity are used to identify each member of a blockchain network. The private key of user is used to digitally sign a transaction when they start it. This signature serves as evidence of ownership and validity because it is particular to the person and the transaction. The user’s public key may be used by others to validate this signature, ensuring that only authorised parties are able to initiate transactions.

9.3.2.3 Secure Communication

Within the blockchain network, peer-to-peer communication is made safe through cryptography. Participants can use encryption to ensure that only the intended receiver can decipher messages and data sent between them. This degree of privacy is necessary to preserve confidentiality and safeguard sensitive information.

9.3.2.4 Consensus Mechanisms

Many blockchain networks based their consensus methods on cryptographic challenges and algorithms. To add new blocks to the blockchain, for instance, miners must solve complex cryptographic problems using the proof-of-work (PoW) agreement mechanism. This computational labour prevents Sybil assaults and guarantees that legitimate nodes continue to govern the network.

9.3.2.5 Public and Private Keys

On the blockchain, public and private key pairs serve as the base for user identities and secure transactions. Public keys act as addresses to which other people can send digital currency or exchanges of information. Contrarily, private keys are used to sign transactions and must be kept a secret. Security and authenticity are guaranteed by the mathematical link between these keys, an outcome of asymmetric cryptography.

9.3.2.6 Zero-Knowledge Proofs

Information may be verified using sophisticated cryptographic techniques like zero-knowledge proofs without disclosing the underlying data. This is especially useful for protecting transactional confidentiality and verifying specific claims without providing unnecessary information.

Blockchain technology’s foundation for security and trust is cryptography. Data integrity is protected, transaction authenticity is confirmed, secure communication is made possible, and consensus processes are powered. Cryptography continues to be a key instrument in assuring the robustness and dependability of these decentralised networks as blockchain continues to develop and confront new problems.

The following is a list of blockchain using cryptography benefits:

Encryption: Asymmetric encryption is employed by cryptography to make sure that network transactions shield conversations and information from unauthorised access and disclosure.

Immutability: This encryption characteristic is crucial to the blockchain since it permits blocks to be safely connected to one another and ensures the accuracy of the data contained there. It also ensures that no attacker may get an authentic signature for uncontested demands and for the signatures associated with those queries from previous inquiries.

Security: Using private as well as public keys to encrypt and access data, cryptography makes transaction records easier to store and retrieve. Since cryptographic hashing makes it hard to manipulate data, the blockchain is more secure.

Scalability: Cryptography makes the transaction irreversible and guarantees that every user can rely on the accuracy of the digital ledger. This feature enables you to safely record an infinite number of transactions on the network.

The main data structure of the blockchain system is as follows. Many blockchain technologies used to produce digital currencies currently depend on the Bitcoin blockchain. A Merkle tree structure (Figure 9.1) is employed for generating the transaction’s root seed value [7]. A Merkle tree has the objective of addressing the issue of authenticity through repeated one-time signatures. The Merkle trusted tree structure offers an essential benefit in authentication, as well as the ability to accommodate several signatures simultaneously. A Merkle tree will be present in every block, and it will begin at the leaf node (bottom of the tree), which is a transaction hash (bitcoin uses a double SHA256 hash). There must be twice as many leaf nodes. Because the most recent leaf node (the last operation in the Merkle tree, not the block’s final transaction) is copied into a double number even though the number of operations in a block is single. Connect two node hashes from bottom to top, then employ the final hash as the new hash. The new tree node represents the new hash. Continue this until the tree’s root is the only node remaining. The root hash is then incorporated into the block header as the sole indicator of the entire block transaction as proof-of-work.

9.4 SECURITY AND CHALLENGES

Public key cryptography ensures the security of transactions on the blockchain. Each member of the network has a set of public and private keys that are used to encrypt data and create digital signatures.

Additional risks linked with blockchain technology include denial of service attacks (DoS), endpoint security, illegal behaviour, code risks, and data security; however, the processes by which these kinds of assaults originate vary [8]. Aside from DoS attacks (denial-of-service), other methods of cyberattacks include hijacking the border gateway protocol (BGP) by modifying routing messages, routing attacks that slow down block transmission or isolate specific areas of the blockchain network, eclipse attacks that conceal a victim from the network’s activity, and EREBUS attacks that use nefarious transit autonomous devices (ASes) as man-in-the-middle networks of nodes on the Bitcoin network to figure out the decision of the nodes as a stealthier attack or remote channel attack.

Among the most well-known cryptocurrency attack techniques is the 51% attack [9]. It revolves on the idea that just a couple of miners command more than half of the computing capability of the network. The attackers would be able to block firms and customers from obtaining confirmations, thus preventing new transactions. Attackers finish proof-of-work more quickly than honest miners. Their transactions will then be connected to the longest chain. Blockchain attacks are more common as mining hash rates grow. Attackers who command more than 50% of the network’s mining hash rate may carry out a 51% assault to reverse transactions despite spending the same amount of money.

9.4.1 BLOCKCHAIN USE CASES

The several essential uses of the blockchain system and the fundamental argument for utilising them are described [10].

Cross-Border Remittance Growth and Trans-Border Transaction Cost Reduction:

The following is a description of the key uses for blockchain technology and why they are important [10]:

Cross-border remittances can be improved, and transaction costs can be lowered. The high cost of transactions between countries poses challenges for banks and organisations worldwide. Models sometimes need three days or more to execute these transactions. To cope with these issues, companies like Ripple are increasingly dependent on blockchain systems and crypto-currencies. The Ripple network currently spans six continents and includes over 40 nations. Blockchain technology enables low-cost, near-instant cross-border transactions.

Following document verification, inefficient supply networks can be eliminated and costs reduced.

Trade financing and supply chain transactions often take several days to execute. This is the outcome of a manual annotation process. In addition to scams, inefficiencies, and costly expenses, the method is rated highly ineffective. Several blockchain-based technologies are being used to solve this problem. These include the Digital Trade Chain, which is controlled by a number of organisations, IBM Batavia, R3 Marco Polo, and the Hong Kong Trade Finance Platform. These transactions might be accomplished rapidly at just a small percentage of the cost.

9.4.1.1 Risks to Data Privacy and Blockchain in Business

A database with every transaction accessible to the public is a less prevalent and more enticing choice for hackers. The blockchain preserves data in a more secure manner, reducing vulnerability and protecting data ownership through an increased level of encryption. Every other day, an organisation’s data gets compromised, affecting many people. Despite the fact that blockchain can safeguard customer data, outages are still an issue. Decentralised blockchain servers guarantee that they remain safeguarded.

9.5 APPLICATIONS AND FUTURE TRENDS

DeFi is a new paradigm that has implications for the design, shipment, and utilisation of financial services. The basic idea is that financial services are inappropriately offered only by centralised intermediaries such as lenders, brokers, stock exchanges, or insurance firms. Rather than being exposed to counterparty risk, financial services should be delivered by users for users employing decentralised software installed across a peer-to-peer network. DeFi attempts to enable customised financial interactions between customers, whether via lending and borrowing, asset speculative thinking diversification, income generation, or direct insurance purchasing [11].

NFT: A nonfungible token (NFT) is a “cryptographic property on a blockchain containing unique identifying data as well as codes that separate them from each other,” stated Peres et al. [12]. Innovative technologies such as blockchain have the capability to tackle concerns related to privacy, security, and scalability [13].

9.5.1 BLOCKCHAIN CONSENSUS MECHANISM

Consensus building makes certain that the elements of each block correspond through the addition of auditing nodes to the blockchain network and verifying transaction data.

The proof-of-work process was used in the initial Bitcoin blockchain. To ensure consistent accounting for bitcoin-network-dispersed accounting, this technique heavily relies on node processing speed. To ensure the integrity and safety of the whole network’s blockchain data, the PoW procedure relies on computing competition among distributed nodes. Each node must rely on its own computer ability to handle the SHA256 algorithm calculation test, which is to find a suitable random number so that the SHA256 digest value of the first block’s header data is less than the setting value.

Consensus formation makes sure that the components of each block correspond through introducing auditing nodes to the network’s blockchain and monitoring transaction data.

The proof-of-work process was used in the early Bitcoin ecosystem. To ensure consistent accounting for bitcoin-network-distributed accounting, this method heavily relies on node processing speeds. To ensure the stability and security of the whole network’s blockchain data, the PoW procedure relies on mathematical competition among scattered nodes. Each node must rely on its machine’s ability to handle the SHA256 algorithm calculation test, which is to find an acceptable random number so that the SHA256 hash value stored in the original block header data is less than the setting value.

Researchers have offered multiple methods that can be performed without the use of computer power in light of the developments of blockchain software and the introduction of competitor currencies. Certain methods for consensus, such as PoS and DPoS, as well as decentralised consistency techniques such as PBFT and Raft, offer benefits and drawbacks that vary depending on the context of the application.

9.6 CONCLUSION

Blockchain technology is utilised by cryptocurrencies for ensuring security and transactional procedures. Specifically, both the blockchain technology platform and the technology itself boost the security of cryptocurrencies. Data has been verified and securely preserved through blockchain technologies such as hashing encryption, electronic signatures, asymmetric encryption, distributed records, smart contracts, and peer-to-peer networks.

Cryptography provides the necessary tools and methodologies to address many of the safety risks linked to blockchain technology by enabling the establishment of distributed, transparent, and secure networks. As blockchain technology evolves and finds applications in a variety of sectors, the necessity of cryptography in maintaining the security and integrity of these distributed systems grows. It is a critical component that allows consumers and organisations to have trust in the security and reliability of blockchain-based solutions.

10.1 INTRODUCTION

Blockchain technology has recently emerged as a groundbreaking innovation that has the potential to revolutionize numerous industries as well as established business practices. Since 2008, when Bitcoin, the first cryptocurrency, was released, it has attracted a great deal of attention and has been adopted by many people.

At the fundamental level, blockchain technology can be understood as a decentralized and distributed ledger system that enables the secure and transparent recording of transactions. It runs on a network of computers, known as nodes, and each transaction is verified and recorded as a “block” before being linked chronologically to form an immutable chain. Due to its decentralized nature, there is no need for any kind of mediator, resulting in a significant increase in both safety and trust.

One of the most significant advantages of blockchain technology is its ability to ensure the transparency and honesty of financial transactions. Because all network participants have access to the same information, it becomes difficult to falsify or manipulate data. This creates a verifiable and auditable record of all transactions that can be accessed at any time. This capability has significant repercussions for industries such as banking, supply chain management, healthcare, and others that recognize the significance of traceability and transparency in their operations [1].

The ability of blockchain technology to simultaneously increase efficiency and decrease costs is another essential aspect of this technology. By eliminating the need for intermediaries, blockchain technology facilitates peer-to-peer financial transactions. This reduces transaction costs and eliminates delays. Moreover, smart contracts, which are agreements that autonomously carry out their terms and are encoded on blockchains, automate and simplify a variety of operations, thereby significantly enhancing their efficacy and precision. The primary reason for the significance of blockchain technology is its ability to address problems that have persisted for a long time in traditional systems, such as fraud, a lack of transparency, and inefficiency. Blockchain technology has the potential to transform entire industries and create new opportunities for organizations and individuals by providing a secure and transparent platform.

Despite this, blockchain technology presents several challenges and considerations in addition to its immense potential. This includes concerns regarding scalability, interoperability, privacy, and legal frameworks. Moreover, as technology continues to advance, it is essential to address the legal and governance aspects of the network, including the dispute resolution procedures that are unique to block-chain transactions.

Given the widespread adoption of blockchain technology in many industries, it is crucial to understand its implications and explore possible ways to solve problems This review on blockchain dispute resolution (BDR) aims to examine this evolving topic for its important characteristics, potential advantages and disadvantages, as well as potential answers to be explored across sectors. We can ensure the proper use and wide adoption of this game-changing technology by first understanding and then applying effective blockchain-specific dispute resolution mechanisms. The development of blockchain technology has brought many positive effects, most notably increased transaction flexibility, security, and efficiency, but blockchain is not as susceptible to disagreements and conflicts between stakeholders as other tools. For failed agreements or disagreements over the interpretation of rules in the blockchain ecosystem, it is essential for blockchain transactions to have their own dispute resolution system to ensure the just and expeditious resolution of any disputes that may arise, to maintain participants’ trust in one another, and to safeguard the integrity of the technology as a whole. Conventional approaches to conflict resolution, such as going to court or using arbitration, may not be optimal when applied to the distinctive properties of blockchain technology, such as its decentralized nature and the security provided by cryptography.

The purpose of this research on blockchain dispute resolution (BDR) is to investigate and undertake an analysis of the existing methodologies and upcoming trends in the field of resolving disputes that arise within blockchain transactions. The purpose of the study is to identify the challenges and opportunities presented by blockchain technology in the context of dispute resolution and to propose effective methods for resolving conflicts in a decentralized and trustless environment. By achieving this objective, we will be able to contribute to the establishment of a robust and effective framework for resolving conflicts within blockchain ecosystems, thereby fostering widespread adoption and trust in this game-changing technology.

10.2 OVERVIEW OF BLOCKCHAIN DISPUTE RESOLUTION (BDR)

The term “blockchain dispute resolution” (BDR) refers to the specialized procedure and tools designed to resolve conflicts, disputes, and disagreements that arise within blockchain transactions or decentralized applications. It entails the resolution of disputes involving smart contracts, transactional blunders, breaches of contractual obligations, governance issues, and other disagreements that may arise in the context of blockchain technology.

Alternative dispute resolution (ADR) encompasses a variety of dispute settlement procedures, including negotiation, mediation, arbitration, and adjudication. These techniques are intended to facilitate the equitable and efficient resolution of disputes, considering the unique characteristics of blockchain technology, such as its decentralized nature, immutability, and lack of central authority.

BDR is cognizant of the need for individualized measures to be taken to address problems that arise in blockchain ecosystems [2]. It involves the use of novel approaches, such as the resolution of disputes based on smart contracts, the establishment of decentralized arbitration platforms, or the development of particular dispute resolution protocols utilising blockchain technology. These mechanisms endeavor to maintain transparency, impartiality, and the enforcement of dispute resolutions, while preserving the privacy, security, and efficiency advantages of blockchain technology. These objectives can be attained by ensuring that dispute resolutions are open, unbiased, and enforceable. The concept and scope of blockchain dispute resolution (BDR) also encompasses the creation of appropriate legal frameworks, governance structures, and standards to regulate the dispute settlement procedures within blockchain ecosystems. It requires consideration of the jurisdiction, the applicable laws, the dispute resolution method, and the role that decentralized autonomous organizations (DAOs) and blockchain communities play in the conflict resolution process. As blockchain technology continues to develop and gain widespread adoption, it is anticipated that the definition and scope of block-chain data resiliency will expand to accommodate new challenges and future concerns. By defining and refining BDR, we can develop a robust and adaptable framework that supports fairness, trust, and accountability within blockchain ecosystems. This will increase the credibility and potential of this revolutionary technology.

10.3 PRINCIPLES OF BDR

BDR is a novel approach to conflict resolution that distinguishes itself from more conventional dispute resolution systems by incorporating fundamental tenets and characteristics. These features and ideas are intended to address the unique characteristics and challenges associated with conflict resolution in blockchain transactions and decentralized ecosystems. Blockchain dispute resolution (BDR) is an initiative that promotes decentralized dispute resolution procedures. This is an acknowledgment of blockchain technology’s decentralized nature. Instead, it utilizes the blockchain’s capabilities for smart contracts and consensus mechanisms to facilitate decentralized decision-making and dispute resolution. BDR utilizes blockchain technology’s immutability and transparency. Recordings of conflict resolution procedures can be stored on a blockchain, providing an immutable and independently verifiable log of the events. This transparency inspires confidence among participants and permits evaluation of the decision-making process. BDR employs smart contracts to automate certain aspects of the dispute resolution procedure. The resolution process can be expedited with the aid of smart contracts, which can be programmed to execute specified actions in response to specific triggers and circumstances. This reduces the need for interpersonal contact [3].

10.3.1 ENTITIES THAT ARE BOTH IMPARTIAL AND OBJECTIVE

BDR places a heavy emphasis on the use of neutral and objective third parties in the resolution of conflicts. These parties may take the form of specialized mediators, arbitrators, or decentralized autonomous organizations (DAOs), all of whom enjoy the respect of the blockchain community and are endowed with the knowledge required to objectively evaluate and resolve disputes.

The objective of alternative dispute resolution (ADR) is to provide efficient and cost-effective dispute resolution procedures. By eliminating the need for intermediaries, automating and digitising procedures, and employing digital technology, BDR reduces the amount of time and money expended on traditional methods of conflict resolution.

Compliance and Enforceability: Behavioral dispute resolution (BDR) recognizes the importance of complying with applicable rules and regulations and ensures the enforceability of dispute resolutions. BDR also guarantees the implementation of dispute resolutions. To accomplish this objective, it may be necessary to combine traditional legal systems and procedures with blockchain technology to establish a legal framework for the resolution of disputes.

Flexibility and Adaptability: Blockchain dispute resolution (BDR) recognizes the significance of flexibility and adaptability to accommodate the ever-changing nature of blockchain technology and the emergence of new challenges in the field of dispute resolution. It enables the investigation of new methodologies, protocols, and standards for resolving novel conflicts and ensuring the ongoing effectiveness of BDR mechanisms.

BDR provides a framework that corresponds to the decentralized and trustless character of blockchain technology by incorporating these essential elements and ideas. This framework provides efficient, transparent, and enforceable dispute resolution mechanisms for blockchain ecosystem participants.

10.4 TYPES OF DISPUTES ADDRESSED BY BDR

Blockchain dispute resolution (BDR) is a project aimed at resolving various disagreements caused by blockchain transactions or arising in decentralized ecosystems. Conflicts arise from various sources, such as technical difficulties, contractual conflicts, governance conflicts, fraudulent practices Lasya violence, protocol incompatibilities, and data integrity issues. BDR provides a means to resolve these disagreements and restore the normal functioning of the blockchain system.

With respect to contractual disputes, smart contracts, which are self-contained contracts stored on the blockchain, can sometimes lead to disputes or breaches of contract. BDR provides a mechanism for understanding and enforcing smart contract terms. This helps to ensure that contractual obligations are met and that disputes are resolved fairly and effectively.

Conflicts over governance are common in decentralized blockchain networks, which typically use community-driven governance structures with consensus-based policy decisions, but disagreements arise over decision-making processes, voting procedures, and resource allocation. BDR is a forum for resolving governance disputes and reaching consensus among the participants. BDR functions as a forum for resolving governance disputes and fostering participant consensus.

10.4.1 CONCERNS REGARDING SECURITY AND DISPUTES REGARDING FRAUD

Blockchain technologies are not immune to fraud or security vulnerabilities. BDR can manage disputes arising from illegal transactions, identity theft, hacking incidents, and fraudulent claims. Within the scope of blockchain’s decentralization, it enables affected parties to seek solutions and hold accountable those responsible for the issue.

10.4.2 COMPLIANCE DISPUTES

As the use of blockchain technology becomes more widespread, the potential for disputes in meeting legal and regulatory obligations increases. BDR can help resolve these disputes by ensuring compliance rules and regulations and unique characteristics of blockchain systems.

10.4.3 INTELLECTUAL PROPERTY DISPUTES

The fact that blockchain platforms can be used to create and manage digital assets including intellectual property makes it useful for resolving disputes over such assets. Blockchain dispute resolution (BDR) protocol provides a mechanism for mediation of disputes over intellectual property ownership, usage, and infringements can be enhanced. Focusing on various types of disputes provides a unique and individual approach to dispute resolution in the blockchain ecosystem. It provides a reliable and efficient mechanism for dispute resolution considering the unique governance, technical, and legal characteristics of blockchain transactions and decentralized ecosystems.

10.5 BDR MECHANISMS AND APPROACHES

Blockchain Dispute Resolution (BDR) resolves various conflicts originating via blockchain. Traditional legal systems fail to resolve blockchain-related disputes because of jurisdictional issues, decentralization, and pseudonymity. By working directly within the blockchain environment, these techniques enable smart contracts and decentralized protocols to be used to settle disputes. The dispute resolution mechanism can be broadly divided into 2 types:

On-chain dispute resolution: These techniques work directly within the blockchain setting, allowing conflicts to be handled via smart contracts and decentralized protocols.

Off-chain dispute resolution: Considering smart contracts alone may not resolve all issues, off-chain procedures offer an alternative that incorporates legal enforcement.

The blockchain dispute resolution approaches can be broadly divided into:

Arbitration Based Smart Contracts: Smart contracts have predetermined arbitration rules that the parties agree to. An arbitration function that carries out preset actions (such as fund release or reversal) is triggered by disputes.

Decentralized Courts and Crowdsourced Jurors: Members of the community serve as jurors and cast votes on the resolution of disputes. Fair decision-making is ensured by token-based incentives (e.g., staking systems to penalize dishonest votes).

Legal-Tech Hybrid Solutions: It combines the use of smart contracts with regular courts.

Community-Based Dispute Resolution: DAOs (Decentralized Autonomous Organizations) use token-based governance to settle internal conflicts.

Traditional Arbitration and Blockchain Integration: The parties agree to resolve disputes through recognized arbitration agencies. To ensure transparency, blockchain records arbitration agreements, evidence, and verdicts.

BDR procedures combine technology, arbitration, and legal frameworks to produce fair, efficient, and decentralized dispute resolution systems. To bridge the gap between blockchain autonomy and legal enforceability, the future of blockchain dispute resolution will most likely combine on-chain automation with decentralized juror systems.

10.5.1 DISPUTE RESOLUTION PROCESSES AND LEGAL PROCESSES

The formation of existing systems is essential. This may involve dispute resolution procedures that comply with substantive legal and regulatory procedures, involve the intervention of competent courts or tribunals, and result in judgments or decisions that recognition and implementation of appropriate regulatory framework results. But the establishment of international standards and agreements, as well as the continuous expansion of the regulatory framework for blockchain technology, helps address these concerns. It is important for industry stakeholders to collaborate with legal experts, regulators, and industry organizations to address these issues. This is because blockchain dispute resolution continues to evolve and becomes increasingly important as it does so.

10.6 CHALLENGES AND CONSIDERATIONS IN BDR

10.6.1 JURISDICTIONAL ISSUES AND LEGAL ENFORCEABILITY

Important considerations in the context of blockchain dispute resolution are jurisdictional issues and the capacity to be legally enforceable. Due to blockchain technology’s inherent characteristics of being decentralized and transnational, it can be difficult to determine which jurisdiction has jurisdiction over a particular case. When parties from different nations or regions are involved in a dispute, the question may arise of whose legal framework should be applied to the situation and which court or arbitration body has jurisdiction. Moreover, the enforceability of the results of dispute resolution is essential for ensuring that parties will adhere to the decisions reached. It is necessary for blockchain dispute resolution mechanisms to navigate existing legal systems and regulations for their decisions to be effectively enforced. This requires addressing issues such as the recognition and enforcement of arbitral decisions as well as the enforceability of smart-contract-based decisions [4].

The fact that DAOs don’t have a physical location makes jurisdictional claims much more difficult. It could be challenging to enforce a court decision rendered in one jurisdiction in another. Unlike traditional contracts in which participants are located within distinct legal systems, blockchain transactions take place across many jurisdictions [5].

Numerous alternative courses of action have been investigated to resolve these issues. Certain procedures for conflict resolution directly address the issue of jurisdiction by providing rules and guidelines that can be used to determine which laws and jurisdictions apply in each circumstance. To provide a transparent legal framework for the resolution of disputes, they may also include provisions regarding the choice of law or the application of rules for arbitration procedures. Moreover, to ensure that laws can be legally enforced, it is often necessary to synchronize the dispute resolution processes of blockchains with existing legal mechanisms. This may involve the development of methods for conflict resolution that adhere to the necessary rules and regulations, the guaranteeing of the participation of qualified arbitrators or mediators, and the production of decisions or awards that can be recognized and enforced within the appropriate legal frameworks.

Even though questions of jurisdiction and the legal enforceability of agreements continue to be complex considerations, the establishment of international norms and agreements, as well as the continued expansion of legal frameworks surrounding blockchain technology, is helping to alleviate these concerns. It is imperative that industry stakeholders collaborate with legal experts, regulatory bodies, and industry organizations to navigate these issues and establish a robust, globally recognized framework for jurisdiction and enforceability in blockchain-related disputes. This is because blockchain dispute resolution is continuing to develop, and as it does so, it will grow in significance [6].

10.6.2 TECHNICAL COMPLEXITIES AND SCALABILITY

In the context of blockchain-based dispute resolution, technical challenges and scalability are crucial factors to consider. Even though blockchain technology offers transparency, immutability, and decentralization, it also presents significant technological challenges that have the potential to compromise the efficiency and efficacy of dispute resolution processes. Scalability is one of the fundamental technical obstacles that must be surmounted. As the volume and complexity of blockchain transactions and smart contracts continue to increase, it is conceivable that the network’s ability to process and validate transactions on the blockchain will become strained.

This could lead to delays in the dispute resolution proceedings, which is especially problematic in situations where time is critical. Integration of traditional legal procedures with blockchain technology represents an additional challenge to surmount. Numerous legal systems and procedures were developed for conventional conflict resolution, and it may be difficult to adapt them to blockchain-based conflicts. For parties involved in blockchain-based dispute resolution, bridging the distance between legal requirements and technological capabilities is a substantial obstacle that must be surmounted.

In addition, the technical complexities of smart contracts and the way they are executed may influence the outcomes of disputes. There is the potential for disagreements or exploitation if the blockchain-stored smart contract code contains flaws or vulnerabilities. Smart contracts are agreements that can carry out their provisions automatically. To effectively interpret and address the underlying issues, it may be necessary to have both legal and technical expertise in order to resolve smart-contract-related disputes.

To address these issues, ongoing research and development efforts must focus on scaling up blockchain networks, interconnectivity between blockchain platforms, and customized arrangements for disputes resolution processes, in addition to ensuring the integrity of processes, the establishment of specialized technical committees, industry standards and best practices can all contribute to an efficient and effective blockchain-based dispute resolution process. This can be achieved by addressing technical challenges and scalability issues.

10.6.3 PRIVACY AND CONFIDENTIALITY CONCERNS

In the context of blockchain-based dispute resolution, privacy and confidentiality concerns are crucial factors. Even though blockchain technology provides transparency and cannot be altered, it presents challenges when it comes to protecting the privacy of sensitive information during the dispute resolution processes. One of the primary concerns is the dissemination of private data on a distributed public ledger [7]. Traditional dispute resolution procedures typically involve the exchange of sensitive and confidential information between disputing parties. This may include financial information, intimate details, or confidential business data. If this information were stored on a public blockchain, anyone with access to the blockchain network could potentially view it, compromising its security.

There are numerous potential solutions for this issue. One possibility is the use of permissioned or private blockchains, in which users’ access to the network is restricted to those who have been granted permission to do so. This allows for greater control over who can read and access sensitive information, thereby preserving the data’s confidentiality to some extent. The use of encryption techniques, such as zero-knowledge proofs or secure multiparty computation, is another method that can be implemented to guarantee the confidentiality of data stored on a blockchain.

Also of concern is the so-called right to be forgotten, also known as data erasure. The immutability of blockchain presents several difficulties when it comes to removing or altering data that has been recorded on the blockchain, as the data cannot be modified. This may be in violation of certain privacy regulations or legally mandated data deletion procedures. To address the right to be forgotten and provide a method for the deletion or modification of data, it is feasible to investigate mechanisms such as off-chain storage or the utilization of side-chains. In addition, the use of pseudonyms or cryptographic identifiers can be an effective method of safeguarding the privacy of parties involved in the dispute resolution process. Using cryptographic techniques, the true identities of individuals and organizations can be concealed while maintaining their verifiability and accountability within the blockchain system. This is made possible by the utilization of ciphers [8].

It is of the uttermost importance that platforms and methods for blockchain-based dispute resolution include privacy-enhancing technologies and comply with all applicable data protection laws. To maintain people’s faith and trust in blockchain-based dispute resolution procedures, it is essential to find a balance between transparency and anonymity.

10.7 STANDARDIZATION AND INTEROPERABILITY OF BDR MECHANISMS

Standardization and interoperability are two of the most essential factors to consider when developing and implementing blockchain dispute resolution (BDR) processes. In light of the ongoing development of blockchain technology and the emergence of new approaches to BDR, it is essential to establish standards and promote interoper-ability in order to ensure the efficacy and productivity of dispute resolution procedures. Essential to the standardization process is the development of standardized protocols, procedures, and recommendations for BDR processes. This includes the development of standardized procedures, technical specifications, and best practices applicable to a variety of systems and platforms. The BDR processes become more predictable and transparent as a result of standardization, which contributes to process consistency. In addition, it facilitates the incorporation of alternative dispute resolution (ADR) mechanisms into existing legal frameworks and conventional methods of conflict resolution.

The term “interoperability” refers to the capacity of multiple BDR mechanisms to collaborate effectively with one another. It allows the parties to choose the BDR mechanism that will be most effective in resolving their specific dispute, while ensuring compatibility and the ability to share information across a variety of platforms. Interoperability enables parties and arbitrators to readily move between various BDR systems and gain access to relevant information or evidence, regardless of the particular platform or technology in use. In the realm of business disaster recovery (BDR), initiatives to standardize and interoperate are currently ongoing. The International Organization for Standardization (ISO) and the International Chamber of Commerce (ICC) are two international organizations that are actively developing standards and guidelines for blockchain technology and dispute resolution. These initiatives aim to establish common frameworks for business disaster recovery (BDR) procedures, data formats, security protocols, and other technical characteristics to improve consistency and interoperability among BDR solutions. Standardization and interoper-ability in blockchain dispute resolution (BDR) not only enhance the effectiveness and efficiency of dispute resolution processes but also instill trust and confidence in blockchain technology as a reliable and credible platform for the resolution of conflicts. Standardization and interoperability in BDR are crucial for blockchain’s development. BDR procedures can provide enhanced accessibility, transparency, and efficacy, which can ultimately contribute to the growth and adoption of blockchain technology in the field of dispute resolution. This can be achieved by defining and fostering common standards and interoperability.

10.8 BENEFITS AND IMPLICATIONS OF BDR

The most significant advantages of blockchain dispute resolution (BDR) procedures are their efficiency and cost-effectiveness. Blockchain technology enables more streamlined and automated business dispute resolution (BDR) processes, thereby reducing the need for extensive documentation, manual interventions, and administrative tasks. Using technologies such as smart contracts, which enable the autonomous execution of predetermined activities and eliminate the need for intermediaries, can accelerate the resolution process. Moreover, the decentralized nature of blockchain technology permits real-time access to data. This allows parties and arbitrators to retrieve and validate crucial data, evidence, and transactions rapidly. This efficacy reduces costs and shortens the time required to reach a resolution, which benefits all parties involved [9].

BDR is founded on the fundamental values of trust and openness. The inherent properties of blockchain technology, such as its immutability and the transparency of its transactions, increase the transparency of dispute resolution procedures. All evidence and transactional information that is recorded on the blockchain is accessible to the eligible parties and can be confirmed by these parties, thereby maintaining a high level of integrity and accountability. Due to the fact that the parties involved can independently verify the BDR process’s procedures, this transparency fosters confidence in the BDR process’s ability to be fair and accurate. Additionally, it reduces the likelihood of data manipulation or tampering, thereby enhancing the credibility of the dispute resolution process [10].

In addition, BDR has the potential to facilitate decentralized governance and civilian autonomy. Traditional mechanisms of conflict resolution typically use authorities and centralized mediators, both of whom have the power to restrict access, erect barriers, and exert centralized power when channels stop blockchain to make it possible for individuals to participate directly in the solution process. This promotes self-government and empowers citizens to assert their rights. Because of the decentralized nature of blockchain technology, decision-making processes are in fact dispersed, preventing too much concentration of power in a few hands. This approach to decentralization in dispute resolution is a principled form of equality, inclusion, and democracy.

In general, BDR is beneficial to individuals because it increases their efficiency, cost-effectiveness, transparency, reliability, and empowerment.

Second, the inherent uncertainty of climate can result in insufficient capital markets that lead to mispricing and mismanagement of the risk. Third, there needs to be more transparency and rationalization in reporting and accounting for carbon emissions; the lack of these hinders greater participation of investors. Fourth, green projects are more expensive than conventional, leading to concerns over profitability and risk aversion from investors. Finally, political and regulatory uncertainties may exist at both the domestic and international levels and can hinder long-term climate projects [2].

Finance is the management of money, assets, and investments to achieve financial objectives. In the context of climate finance, it is to the allocation of funds to address climate-change-related concerns. Climate finance is essential to help mitigate the impact of environment, but it has several challenges [3]. Even the studies have evaluated the machine learning implications in the health sector [4]. For instance, limited access and lack of coordination in funding, as well as difficulties in tracking the finance, are significant challenges in climate finance [5]. Technology can address these challenges by providing immutable records of transactions, reducing intermediaries, traceability and auditing capabilities, and encouraging collaboration and data sharing with the stakeholders [6].

While the challenges in climate finance are numerous and complex, technology has the potential to play a significant role in addressing these challenges by facilitating more efficient and transparent transactions, reducing costs, and enabling greater access to finance for both developed and developing countries [7]. However, more than technology, the need is to solve challenges coupled with strong policies and regulations, as well as collaborative efforts between governments, financial institutions, and private sector investors in order to ensure that climate finance is going toward sustainable and impactful initiatives [8]. Blockchain technology, in particular, has emerged as a powerful enabler for climate finance, offering a secure and transparent means for tracking and verifying carbon offsets, renewable energy certificates, and climate-related assets.

13.9.3 REDUCING FRAUD AND ENHANCING SECURITY

The transparency and immutability of blockchain create a highly secure environment for financial transactions. Traditional banks are increasingly using blockchain to reduce fraud, detect unusual activities, and enhance the security of their systems. Transactions recorded on a blockchain are tamper-resistant, making it difficult for bad actors to manipulate or compromise data.

BNP Paribas has employed blockchain technology to enhance the know-your-customer (KYC) process. By storing and sharing customer identity information on a blockchain, the bank can ensure data integrity and simplify KYC compliance. This reduces the risk of fraud and identity theft.

13.9.4 ENHANCING CUSTOMER SERVICES

Blockchain technology has the potential to revolutionize customer services in the traditional banking sector. By providing real-time transaction updates, reducing processing times, and enhancing data security, banks can offer customers a more convenient and transparent banking experience.

Wells Fargo, a prominent US bank, introduced Wells Fargo Digital Cash, a digital currency for internal book transfers. This system allows the bank to settle transactions across its global network instantaneously. The enhanced speed and efficiency not only benefit the bank but also provide customers with quicker and more transparent services.

Traditional banks are no longer ignoring the disruptive potential of blockchain technology. The adoption of blockchain by these institutions reflects the growing recognition of the benefits it can offer in terms of improved settlement and clearing processes, reduced fraud, enhanced security, and superior customer services. As the technology continues to mature, traditional banks are expected to further embrace and integrate blockchain into their core operations, ultimately benefiting customers and the financial industry as a whole.

13.11 BLOCKCHAIN REVOLUTIONIZING FINANCE: CASE STUDY

The global financial system faces inefficiencies, high costs, and susceptibility to fraud and crime. Traditional systems, centralized and exclusionary, are in need of innovation. Blockchain technology, initially designed for cryptocurrencies like Bitcoin, offers solutions to these problems. This case study explores the disruptive potential of blockchain in the financial sector, covering its fundamental principles and its impact on reducing friction and costs. It also highlights the opportunities it creates for peer-to-peer mass collaboration and how it transforms the way companies raise capital. This transformative technology can democratize participation in global capital markets but challenges the existing financial system. Will incumbents embrace the revolution or risk becoming obsolete?

The global financial system, which handles trillions of dollars daily and serves billions of people, suffers from a multitude of issues. These problems include costly fees, transaction delays, excessive paperwork, and vulnerabilities to fraud and economic crimes. Shockingly, 45% of financial intermediaries experience economic crime annually (Ghosh, 2019; Massad & Jackson, 2023). These intermediaries include payment networks, stock exchanges, and money transfer services. The corresponding figures for the entire economy, professional services, and the technology sector are 37%, 20%, and 27%, respectively. Regulatory costs are on the rise, and consumers bear the brunt of these issues. The inefficiency of the financial system is a result of its antiquated structure, centralization, and exclusionary nature. While other industries embrace creative destruction, the financial sector often resists change. Blockchain technology has emerged as a solution to these challenges (Amarnani & Amarnani, 2019).

Blockchain is a decentralized, distributed ledger technology that allows secure and transparent record-keeping without the need for a central authority. At its core, blockchain operates through a network of nodes (computers), each of which has a copy of the entire blockchain. These nodes validate and confirm transactions in a manner that ensures data integrity and security. Each transaction is recorded in a “block,” which contains a list of details such as the transaction time, amount, and the participants involved. Once a block is completed, it is linked to the previous block through a cryptographic process, forming a chain of blocks—hence the name “blockchain” (Nakamoto, 2008).

A critical feature of blockchain is its consensus mechanism, which ensures that all participants in the network agree on the state of the ledger. The most common consensus mechanism is Proof of Work (PoW), used by Bitcoin, where nodes solve complex mathematical problems to add a new block to the chain. Other consensus mechanisms, such as Proof of Stake (PoS), aim to improve energy efficiency and scalability (Buterin, 2014). Blockchain also utilizes cryptography to secure data and ensure that only authorized users can participate in the transaction process. This technology ensures that once a block is added to the blockchain, it is immutable and cannot be altered without disrupting the entire chain, making it resistant to fraud and tampering (Swan, 2015).

The transparency and immutability of blockchain technology have made it particularly valuable in sectors such as finance, healthcare, and supply chain management, where secure, traceable, and efficient record-keeping is critical (Tapscott & Tapscott, 2016). However, challenges such as scalability, energy consumption, and regulatory concerns still hinder its widespread adoption (Mougayar, 2016). Nonetheless, block-chain’s potential to reshape industries continues to be explored, especially in the context of digital currencies and decentralized applications (DApps) (Antonopoulos, 2017).

13.11.1 BLOCKCHAIN OPERATES ON A FOUNDATION OF FIVE CORE PRINCIPLES

13.11.1.1 Distributed Database

Parties engaged in the blockchain ecosystem possess unrestricted access to the entire database and its historical records, eliminating central control. Verification processes occur directly among involved parties without the need for intermediaries.

13.11.1.2 Peer-to-Peer Transmission

Communication within the blockchain network takes place directly between peers, fostering an environment where information is exchanged seamlessly among all network nodes.

13.11.1.3 Transparency with Pseudonymity

Transactions and associated values are observable to those with system access. Users maintain unique alphanumeric addresses, providing the option for either anonymity or identity verification.

13.11.1.4 Irreversibility of Records

Transactions, once recorded, attain a permanent and unalterable status, forming a chronological chain that reinforces the integrity of the blockchain.

13.11.1.5 Computational Logic

The programmable nature of blockchain transactions allows for automation using algorithms and predefined rules, enabling automatic execution between nodes.

Initially devised for cryptocurrencies like Bitcoin, blockchain technology has transcended its origins to encompass the secure, private, and peer-to-peer movement and storage of assets. Trust within the blockchain system is established through a combination of network consensus, cryptography, collaboration, and code.

13.11.2 BLOCKCHAIN IN FINANCE: REDUCING FRICTION AND COSTS

Blockchain introduces opportunities to alleviate friction and reduce costs within the financial sector. By diminishing transaction costs among participants, blockchain facilitates peer-to-peer mass collaboration, rendering many existing organizational structures obsolete. For instance, it transforms the dynamics of accessing growth capital, enabling globally distributed share offerings that allow companies of any size to raise funds peer-to-peer. The potential savings within the financial industry are substantial, with estimates suggesting annual savings of $20 billion by Santander and potential consumer savings of up to $16 billion in fees annually through block-chain applications according to Capgemini.

13.11.3 TRANSFORMATIONAL POTENTIAL OF BLOCKCHAIN

Blockchain’s transformative potential extends to various intermediate functions in the financial industry, encompassing identity and reputation management, payment and remittance services, savings and lending, trading value, insurance and risk management, as well as audit and tax functions. The technology challenges existing financial infrastructure by enabling innovative capital-raising methods. In 2016, blockchain companies secured significant funding, with USD 400 million from traditional venture investors and nearly USD 200 million through initial coin offerings (ICOs). This transformational technology has attracted investments from both traditional incumbents and new players, potentially rendering existing business models obsolete (Schatsky & Muraskin, 2015).

13.11.4 CONCLUSION: EMBRACE OR GO OBSOLETE

Blockchain technology emerges as a formidable game-changer for the financial sector, challenging existing systems while providing avenues for innovation and efficiency. Incumbents in the industry face a critical decision—to lead the revolution or risk obsolescence. Blockchain presents a trajectory toward democratizing global capital markets, and its impact hinges on how the financial industry adapts to this transformative change.

13.12 CONCLUSION

In conclusion, blockchain technology has emerged as a transformative force within the finance sector, offering a new paradigm for the way financial transactions and services are conducted.

The adoption of blockchain in finance is an exciting journey that offers opportunities to redefine traditional financial practices. It is imperative that stakeholders across academia, industry, and regulatory bodies collaborate in the pursuit of a more efficient, secure, and inclusive financial ecosystem.

Blockchain has the power to reshape the financial landscape by fostering peer-to-peer mass collaboration and reducing transaction costs for all participants. One example is the ability for companies of all sizes to raise funds through peer-to-peer global distributed share offerings, bypassing traditional intermediaries. ICOs (initial coin offerings) have emerged as a way to fund blockchain ventures, attracting both traditional venture investors and individual backers. As blockchain transforms various functions in the financial industry, it could render many existing organizational forms redundant, impacting identity, payments, savings, credit, marketplaces, insurance, risk management, and audit functions.

The financial industry is on the cusp of a significant transformation due to block-chain technology. Those who embrace this paradigm shift from within the industry can adapt to the changing landscape. The collision of blockchain with traditional finance is inevitable, and its impact on the industry’s structure will create both winners and losers. The future of banking as we know it may be in question, but the opportunities for innovation and positive change are immense.

14.1 INTRODUCTION

With time, blockchain technology has evolved to allow for the integration or fusion of decentralized applications with further technologies. Blockchain makes use of a distributed ledger that is kept up-to-date by a number of nodes connected via networks; these nodes are in charge of communicating with one another and recording transactions [1]. Based on vehicle-to-infrastructure authentication, a number of works have been presented for safeguarding Internet of Vehicles (IoV) settings; nevertheless, some approaches have efficiency concerns and security flaws. IoV security may be addressed by blockchain, an emerging technology, due to its decentralization, reliability, and transaction monitoring features [2].

Because of its decentralized and tamper-proof characteristics, blockchain is increasingly employed in the administration of healthcare data. This chapter assesses the evolution of blockchain technology in healthcare from a number of angles. It examines blockchain-based strategies in several use cases [3]. Another article proposes a dynamic blockchain-based identity management system (B-IMS) with mutual authentication between user equipment (UE) along with service providers (SP), incorporating dynamic chameleon hash keys and dynamic cryptographic key generation to enhance system reliability [4].

Nevertheless, dispersed networks are not a good fit for the trust mechanisms now in use. Consequently, this study proposes a framework, designs a trust mechanism rooted in blockchain consensus, and offers a cloud-edge structure based on block-chain technology. It achieves device mutual trust through the use of BLS-based proof of replication (PoRep) as a consensus method [5]. The model suggests proof-of-energy reputation creation as well as proof-of-energy reputation consumption consensus procedures as a solution to the problems caused by the current consensus techniques’ high computing costs and significant financial investments. Similarly, in order to prohibit cheating assaults in the model, a mutually verifiable fairness method rooted in time commitment is implemented [6].

The adversary has discovered several ways to threaten the Internet of Things (IoT) communication channel due to the market’s exponential expansion in IoT devices as well as the weaknesses of ever-improving technology [7]. As a result, research suggests a secure sharing and storing method for electronic learning records (ELRs) in massive open online courses (MOOCs) grounded in blockchain technology. The suggested method, which is built to benefit from blockchain technology, can provide effective conditional anonymity, secure storage, and sharing without requiring complex cryptographic computations [8].

Following is the remainder of the paper structure: The most current developments in blockchain security are evaluated in the next section. The third section provides an overview of the proposed algorithm and its main components. The fourth section discusses how the advantages of the proposed approach stack up against similar studies in the field. The final section provides some potential avenues for further study to round out the research.

14.2 LITERATURE REVIEW

Some of the recent related works related to authentication in blockchain are reviewed in this section.

Liu et al. [9] investigated the safety of IoV in smart transportation based on block-chain. The current work seeks to enhance the communication security of IoV nodes. Digital twins (DTs) and big data are used to create an IoV DTs model. Then, based on the trackable and immutable BC data, a safe communication architecture for the IoV system is suggested in light of the present communication security challenges. Additionally, the IoV node risk forecast model is built using the Wasserstein distance-based generative adversarial network (WaGAN) model. The WaGAN model learns extremely quickly because it uses the Wasserstein distance to compute the loss function.

Sharma et al. [10] discussed security and privacy, which are key concerns due to the resource constraints of radio frequency identification technology (RFID) devices. Additionally, the IoV is a real-time network where security is critical. The idea of elliptic-curve cryptography (ECC) is used while keeping an eye on security. Thus, this work presents a safe ECC-enabled RFID mutual authentication protocol for IoV that is based on cryptographic solutions. There are three steps to the proposed protocol: setup, tag authentication, as well as server authentication. The examination of security needs and security assaults is taken into account while evaluating the proposed protocol security.

Mishra et al. [11] discussed that conventional methods that offer integrated security control and communication protection for smart grids are susceptible to certain types of assaults and restrict their usage in real-time applications, which is inadequate to work the widespread cybersecurity risks in the smart grid network. In order to identify the attack, the statistical function in this study forecasts the timestamp’s system performance and compares it with the actual performance. The user authentication process, which is intricate and adds to network delay, is determined by the asymmetric encryption function. This study proposes a blockchain-based approach that reduces network latency while detecting cybersecurity threats in smart grid networks.

Fasila et al. [12] presented a security approach for IoT applications. The plan suggests using dynamic key generation and layered protection throughout the data uploading and transfer stages to improve security in dispersed IoT applications. The connection among the associated gateway node and the sensing device in existing works is based on a single key. The suggested approach uses the concepts of cellular automata to update the session key at the end of each session. By utilizing the unmatched advantages of blockchain technology, dynamic keys, and random number creation grounded on cellular automata, the suggested method offers layered security. Automated validation of internet security protocols and applications (AVISPA), a well-known security protocol verification tool, was used to test and implement the same.

Wang et al. [13] described numerous trials for cloud-based smart grid systems: achieving low latency as well as providing real-time services. As a result, edge computing is becoming more and more popular. Although several cryptographic protocols have been created to deliver secure communications in smart grid systems, flexible key management as well as conditional anonymity are typically not supported by the methods that are now in use. Therefore, for edge computing-based smart grid systems, this research presents a blockchain-rooted mutual authentication as well as key agreement protocol. In particular, the protocol can provide effective key management as well as conditional anonymity without requiring additional sophisticated cryptographic primitives by utilizing the blockchain.

Ali et al. [14] offered a security architecture for distributed applications based on the IOT. The most well-known lightweight encryption, ChaCha20, is used in the architecture. To increase security and unpredictability in random number generation, cellular automata principles are utilized. During the data uploading and storage processes, multilayered data protection is ensured using double encryption. The approach uses dynamic session keys for encryption, which increases its security. It also ensures rapid execution, message integrity, user authentication, mutual authentication between communicating entities, and safe data exchange. The gateway node-connected IoT device must successfully complete the registration procedure. After that, every time a data transfer takes place among the device along with gateway node, the mutual authentication step is executed.

Cheng et al. [15] presented various authentication systems in their research, but their lack of decentralization, anonymity, and mobility has rendered most of them unsuitable. Motivated by this reality, the research suggests a mutual authentication technique based on blockchain technology that fills up these gaps. In particular, the system integrates blockchain, pseudonym-based cryptography, ECC, along with certificateless cryptography to enable mutual authentication among edge servers along with IoT devices. The intra-edge as well as inter-edge authentication are taken into consideration, excluding static situations. In addition, this work creates a framework for session key negotiation and expounds on the process of key generation.

Li et al. [16] described a reliable and useful two-way authentication method that uses elliptic curves and bilinear pairings to provide federated chain membership authentication. The federated chain supervisor uses smart contracts to directly perform membership authentication. Members exchange keys after key negotiation, and a hash function uses the shared key that results from that process to produce a hash digest that serves as each member’s distinct transaction address. The one-way authentication issue with certification authorities (CAs) and the centralized CA’s easy failure may be resolved with this technique.

Masoodi et al. [17], maintained that, while handy, the ability to remotely access and manage IoT devices’ ability (e.g., taking pictures, videos, and other types of information) carries a danger since weak points in the equipment may be utilized to spy on people and organizations or carry out other malicious tasks. This highlights how important it is to have a secure as well as an efficient remote user authentication system. The majority of current solutions for this issue often rely on a single-server architecture, which has drawbacks in integrity and confidentiality (resulting in unreliable behaviour auditing) as well as privacy and anonymity (allowing users’ daily actions to be anticipated). Even though blockchain-based answers could lessen these problems, they still have to overcome some critical challenges. Despite the fact that a number of works have been presented in the currently available methods, authentication in blockchain is still seen as a problem. However, problems with privacy protection and the management of user behaviour in access policies persist. In order to preserve user privacy and establish the user’s genuine identity according to the data access rules in the case of an unexpected transaction, the authenticity of the sent message must be maintained. As a result, the results of this research are as follows:

In order to gain the required permissions, this research first develops a mutual authentication scheme that shows access request transactions as well as answer data.

All of the request transaction data is encrypted with the aid of a customized elliptic curve encryption method (CECEA) and authenticated with a secret message authentication code.

In order to manage user data access policy and consents, the access request transaction as well as response data are securely encrypted and authenticated.

A secure hash function (SHF) is employed to create public as well as private keys; then even if attackers know the hash function, they will not be able to determine the keys’ true values used to create the hash.

14.3 PROPOSED METHODOLOGY

Access control rules are stored on the blockchain. The absence of privacy protection concerning user access norms while retrieving personal data is an important barrier to the general adoption of the IoT system. It is critical to protect the integrity of the message. Therefore, this research proposes a CECEA algorithm that creates a mutual authentication scheme that presents access request transactions along with response data in a graphical format. It protects against attacks, data loss, and leakage and defends the rules governing user access. Data from each request transaction is encrypted using a CECEA algorithm and verified with an authentication code derived from a secret message. Access request transaction data and answer data are encrypted and verified for user data access policy and permission management. Private and public keys may be generated with the use of a SHF. This function improves privacy protection on the IoT by making it harder to fix the real encryption key value [18].

14.3.1 SETUP

In this phase, the setup procedure is called upon to generate signing and verifying keys. The consequent security is confirmed by first creating a hash function after entering the security parameters λk. to get the public parameters σk. This is because the hash function is needed to calculate the public key δpubk and the private key δprik. To designate the proposed hash produced in response to message msg, it is equated as in Eq. (14.1):

h m s g = ψ m s g | ψ : 0 , 1 * → 0 , 1 512

(14.1)

where this research has utilised SHA-512 as the hashing algorithm termed as ψ [19]. The private and public keys are computed from clearly detectable places on the elliptic curve in certain works, such as [20], putting the user’s privacy at risk. When acquiring user consent prior to processing user data, the strength of the key security guarantees the legitimacy of the communicated message.

The integrity of the sent message for acquiring user consents prior to handling user data in the IoT is guaranteed by the strength of the key security. Therefore, the sent message will be very secure if SHF is employed to calculate the key value instead of selecting publicly available elliptic curve points. Instead of picking a random point on the elliptic curve and then calculating the public key from that point, the secure hash value is employed to construct the private key. With employment of the hash function, the key generator function Γ(.). is employed to produce the private key δprik ; this is mathematically given in Eq. (14.2):

δ p r i k = Γ h | Γ : 0 , 1 * → 0 , 1 512

(14.2)

Once the private key δprik for message msg has been generated using the hash δprik , the matching public key h(msg) may be determined using Eq. (14.3):

δ p u b k = δ p r i k * E i , E j

(14.3)

where Ei,Ej are the i and j coordinates on the finite-field elliptic curve E, and P is a prime with high order [21]. So long as the hash function is kept secret, the value of the key being detected remains safe. Therefore, both the private and public keys are protected, making the user’s privacy more robust against a variety of security threats.

14.3.2 REQUEST CONTROL

To prevent attacks and profiling, when an access request has been made public, new public and private keys are created using the generated hash for the private key computation rather than a new random key. Then the request transaction data is encrypted utilizing a new key as well as a validated one. Improved random key ElGamal encryption (IRKE) [22] is used to encrypt the transmitted message since the arbitrarily produced points on the elliptic curve may be identified as numerous keys. With IRKE, the keys’ origins are hidden from a potential attacker. After keys are produced, the encryption algorithm is applied to the request transaction data, with the encryption process described in Eq. (14.4):

c i p h e r t x t = d a t a   x o r   δ p u b k

(14.4)

where data is the requested data, and ciphertxt is the created ciphertext by using the encryption process.

14.3.3 STATE DELIVERY

At this point, the blockchain network is keeping a close eye on the access request, verifying the transaction employing an algorithm based on digital signatures. The decryption algorithm of CECEA and the private key are used to decrypt the transaction after it has been validated. The decryption process described in Eq. (14.5):

If the private key as well as public key are equal, then the decryption is allowed, and the ciphertext is converted to plain text. If not, then the decryption process does not convert ciphertext to plain text. Both the request for access to the information and the user’s subsequent answer to that request are encrypted and authenticated. To verify that the answer came from an authorised user, this research recalculated the authentication tag. Only if the authentication tag is a match is the user’s encrypted response decoded to provide data about the request’s success. The flow of the proposed CECES is shown in Figure 14.1.

Thus, by this proposed method, the authenticity in blockchain is maintained, and it is proved by comparison with some existing approaches.

14.4 RESULTS AND DISCUSSIONS

The findings and analysis of the proposed strategy are shown in this section. The proposed model’s prototype was built and tested in MATLAB R2019a on a personal computer (PC). Therefore, the efficacy of the proposed CECEA technique is evaluated by looking at data integrity, execution time, and confidentiality rate [23].

14.4.1 DATA INTEGRITY

The accuracy as well as the dependability of stored data are defined as the data integrity rate. In Eq. (14.6), it is formally stated as follows:

D a t a   i n t e g r i t y = n o .   o f   v e r i f i e d   u s e r   d a t a T o t a l   n o .   o f   u s e r   d a t a × 100

(14.6)

Data integrity is determined using Eq. (14.6) with regard to various user data counts. The procedure is considered more efficient when the data integrity rate is greater. The Elliptic Curve Integrated Encryption Scheme (ECIES) [18] and Ethereum scheme [1], as well as the proposed CECEA technique, are used in Table 14.1 to analyse the performance of the data integrity rate on the blockchain. For experimental work, various user data counts are taken into consideration. The proposed CECEA technique achieves a data integrity rate of 93% when seeing the 80 user data points, whereas ECIES and Ethereum reach 87% and 79%, respectively. As a result, when compared to other existing studies, the data integrity rate employing the proposed CECEA technique is greater. SHF and IRKE, which carry out the data verification procedure in the proposed technique, help to accomplish this effective increase in data integrity rate. For each user input, the proposed technique generates a private signing key along with a public verification key. Then, using the input data as well as the private signing key, the data is verified.

TABLE 14.1 Data Integrity Rate

No. of User Data | Data Integrity Rate
Proposed Scheme | ECIES Algorithm | Ethereum Algorithm
20 | 83 | 77 | 70
40 | 86 | 81 | 73
60 | 89 | 84 | 76
80 | 93 | 87 | 79
100 | 96 | 89 | 81

14.4.2 EXECUTION TIME

Execution time, as used in the proposed CECEA approach, gauges how long it takes to store user data and establish a reliable connection and is equated in Eq. (14.7).

E x e T i m e = d a t a   s t o r a g e   e n d   t i m e − d a t a   s t o r a g e   s t a r t   t i m e

(14.7)

The execution time is represented mathematically as, from Eq. (14.7), the execution time required for acquiring trustworthy storage. This is measured in milliseconds (ms). The approach is considered to be more efficient with lower execution time.

The execution time comparison between the proposed CECEA technique and the current ECIES and Ethereum techniques is shown in Table 14.2. The number of user data points used for performing experiments ranges from 20 to 100. The proposed technique requires 21 ms of execution time when 40 user data points are taken into account for experimental work, while ECIES and Ethereum need 25 ms and 29 ms, respectively. As a result, when compared to other existing works, the execution time of the proposed CECEA technique is shorter.

TABLE 14.2 Execution Time

No. of User Data | Execution Time
Proposed Scheme (ms) | ECIES Algorithm (ms) | Ethereum Algorithm (ms)
20 | 15 | 21 | 26
40 | 21 | 25 | 29
60 | 25 | 31 | 32
80 | 30 | 36 | 38
100 | 33 | 39 | 42

14.4.3 CONFIDENTIALITY RATE

When implementing the proposed CECEA technique for secure data transport, data confidentiality is obtained. The data confidentiality rate gauges a system’s capacity to keep data secure and ensure that only authorised users have access to it. The approach is considered more efficient if the degree of data confidentiality is greater in measurement.

The results of comparing the proposed CECEA technique with the already-inuse ECIES and Ethereum systems are shown in Table 14.3. The number of user data points used for performing experiments ranges from 20 to 100. The CECEA technique requires a 97% data confidentiality rate for completing experimental work, compared to 86% and 82% for ECIES and Ethereum, respectively. By creating a hash value for each user’s data, the enormous amount of data used to evaluate confidentiality rates is successfully stored. This leads to an improvement in the confidentiality rate while taking into account more user data. As a result, as compared to other existing studies, the data confidentiality rate utilising the proposed technique is much enhanced.

TABLE 14.3 Confidentiality Rate

No. of User Data | Confidentiality Rate
Proposed Scheme | ECIES Algorithm | Ethereum Algorithm
20 | 85 | 73 | 68
40 | 88 | 76 | 70
60 | 91 | 79 | 73
80 | 94 | 82 | 77
100 | 97 | 86 | 82

14.5 CONCLUSIONS AND FUTURE WORK

The IoT system’s increasing demands have been on data security and user privacy. In this research, a blockchain-rooted method to protect privacy in the IoT is described. The proposed plan offers a safe platform that enables the person requesting access to provide transaction data for the request and get response data for the associated request. This study uses CECEA together with SHF to maintain the privacy of transmitted request transactions and answer data. User privacy in the IoT was improved by employing a SHF to create public as well as private keys. This improvement could strengthen the request transaction data security, which is used to generate keys. The computing time for the proposed solution has thus decreased. Additionally, the proposed strategy performs better when compared to additional criteria like data integrity and secrecy. In order to offer users and data requesters a safe platform to share their data in the IoT environment, it will be necessary to investigate further cryptographic techniques in the future. In order to improve user privacy in the IoT and work in real time, future study has to concentrate on concerns other than preserving the secrecy along with authenticity of the request transaction data.
