Which feature of blockchain technology enhances data integrity?

The enhancement of data integrity in blockchain technology is primarily attributed to decentralized data storage and cryptographic algorithms. Decentralized data storage means that rather than being held in a single location, copies of the data are distributed across a network of nodes. This arrangement significantly reduces the risk of a single point of failure and makes it much harder for malicious actors to alter the data without detection, as changes would need to be made across multiple copies simultaneously.

On the other hand, cryptographic algorithms play a crucial role in ensuring that data stored on the blockchain remains secure and tamper-proof. Each block contains a cryptographic hash of the previous block, which links them together in a verifiable manner. If any data in a block is altered, it would change the hash and break the chain, making any tampering evident. This cryptographic linking, combined with the transparency of the public ledger, provides an additional layer of trust and security, further enhancing the overall integrity of the data.

Other options do not contribute significantly to data integrity in the context of blockchain. For instance, physical storage devices do not inherently guarantee integrity; they are simply the means of storing data. Stringent regulatory compliance requirements might ensure processes are followed, but they do not directly prevent data manipulation. Similarly
