Auditable edits refer to modifications made to a record or system that leave a permanent, verifiable trail of changes. This mechanism ensures that every alteration is logged, including who made it, when it occurred, and what specifically was changed. The primary purpose is to maintain transparency and accountability for data integrity. Such systems allow for independent review and validation of all historical data states.
Context
For blockchain technology and digital assets, auditable edits are fundamental, as the distributed ledger inherently records all transactions immutably. While direct edits to confirmed blockchain data are generally impossible, the concept applies to off-chain data linked to digital assets or smart contract parameters that can be adjusted. Ensuring a clear audit trail for any such off-chain modifications or protocol upgrades is vital for investor confidence and regulatory compliance.
This research surveys how cryptographic mechanisms, primarily chameleon hash functions, enable auditable data modification within blockchains, balancing immutability with regulatory needs.
