Which of the following is a benefit of using blockchain technology in transaction records?

Utilizing blockchain technology for transaction records provides a significant benefit of enhanced security, largely attributed to its foundational cryptographic techniques. Each transaction recorded on a blockchain is secured through cryptographic hashing, which makes it nearly impossible to alter any information without consensus from the network participants. This ensures data integrity, meaning that once a transaction is validated and added to the blockchain, it cannot be changed retroactively, thus providing a tamper-proof record.

Furthermore, the decentralized nature of blockchain means that there is no single point of failure or control, reducing vulnerability to fraud and cyber-attacks. This level of security is especially critical in industries that handle sensitive information or require high trust levels, such as finance, healthcare, and supply chain management.

In contrast, other choices do not accurately reflect the security benefits associated with blockchain. While anonymity can be a feature in certain blockchain applications, it is not universal, and not all transactions allow for complete anonymity. The option suggesting that transactions can be altered easily contradicts the very principle of blockchain's immutability. Finally, while some blockchain implementations do restrict visibility of transactions to certain users, many prominent ones operate in a transparent manner, allowing visibility for all participants on the network.
