Analyzing the Impact of Blockchain Technology on Transaction Security with a Bibliometric Perspective

ABSTRACT


INTRODUCTION
The evolution of blockchain technology is deeply rooted in the pursuit of decentralized, tamper-proof systems, catalyzed by the vulnerabilities inherent in centralized architectures [1].Traditional transaction systems, reliant on intermediaries such as banks and clearinghouses, are susceptible to a myriad of risks, including fraud, manipulation, and data breaches [2].In contrast, blockchain's decentralized nature, facilitated by its peer-to-peer network and consensus mechanisms, presents a paradigm shift in transaction security by eliminating the need for a central authority [3].This decentralization ensures that transactions are recorded transparently and immutably across a distributed ledger, fostering trust among participants and reducing the risk of malicious activities [4], [5].
The foundational principles of blockchain technology center around its distributed ledger, which serves as a transparent and immutable record of transactions across a network of nodes [6].
Through the use of cryptographic techniques, transactions on the blockchain are cryptographically secured, ensuring their integrity and making them resistant to tampering [7].This cryptographic security not only enables verification of transactions but also facilitates trust among participants, mitigating the need for intermediaries to validate and oversee transactions [8], [9].Additionally, blockchain's decentralized architecture and consensus mechanisms ensure that the ledger is maintained by a network of nodes rather than a single centralized entity, further enhancing security by eliminating single points of failure and reducing the risk of data manipulation [10].
The emergence of cryptocurrencies, notably Bitcoin, marked a significant milestone in the adoption and exploration of blockchain technology beyond its theoretical foundations [11].Bitcoin demonstrated the feasibility of a decentralized digital currency, showcasing blockchain's potential to revolutionize financial transactions and challenge the dominance of traditional banking systems [12], [13].Subsequent innovations, such as Ethereum and its introduction of smart contracts, expanded the scope of blockchain applications beyond currency, enabling programmable transactions and decentralized applications (DApps) [14].These developments have spurred a wave of experimentation and innovation across various industries, driving the exploration of blockchain's potential to enhance security, transparency, and efficiency in transaction systems [15].
While blockchain technology holds immense promise for revolutionizing transaction security and transforming numerous industries, it also faces a myriad of challenges and criticisms [16].Scalability remains a persistent concern, with the throughput and latency of blockchain networks often lagging behind traditional payment systems [1].Additionally, the energy-intensive nature of proof-of-work consensus mechanisms, employed by many blockchain networks, has raised environmental concerns and sparked debates about the sustainability of blockchain technology [17].Moreover, regulatory uncertainty, interoperability issues, and privacy considerations pose significant hurdles to widespread adoption and implementation [18].Addressing these challenges requires a multifaceted approach that balances technological innovation with regulatory frameworks and sustainability considerations, ensuring that blockchain's potential to enhance transaction security is realized responsibly and ethically [19]

Blockchain Technology
Blockchain technology is a decentralized system of linked records that are publicly available yet cryptographically secured [20].It functions as a chain of blocks containing time-stamped digital documents, making it tamper-proof and resistant to backdating [21].Utilizing encryption techniques, blockchain ensures secure transmission of information, making it popular across various sectors [22].This technology acts as a safeguard against data leaks, piracy, and manipulation, protecting valuable information for organizations [23].With each node in the network having a copy of the digital ledger, blockchain cannot be corrupted without a consensus, enhancing security in transactions and communication [24].Blockchain finds applications in finance, real estate, voting, logistics, smart contracts, healthcare, and cybersecurity, showcasing its versatility and potential impact across industries .

Transaction Security
Transaction security involves safeguarding data transactions to prevent cyber threats and unauthorized access.In a business setting, Transaction Processing Systems (TPS) play a vital role in handling transaction data securely [25].Implementing security measures like validating transaction requests based on security rules and updating transaction data on a distributed ledger node enhances security in Mobility-as-a-Service platforms [26].Methods such as utilizing Trusted Execution Environments (TEE) for secure operations and employing one-time security data for transaction verification contribute to enhancing transaction security in mobile payment scenarios [25], [27].
Additionally, tracking parties' locations during transactions and providing transaction verification codes through distinct communication channels further fortify transaction security measures [25] .These strategies collectively aim to mitigate threats, ensure data integrity, and enhance the overall security of transactions.
