A hash chain is a tamper-resistant structure in which each block's hash includes the hash of the previous block, so any modification changes subsequent hashes, but if an attacker can recompute the entire chain, it cannot prove its own innocence.

UnverifiedTamper-proof auditing usually relies on hash chains or digital signatures; a hash chain links each log entry's hash value to the previous one, so any tampering breaks all subsequent hashes.74% similarUnverifiedTrue immutability must be embedded in the persistence layer, and any attempt at tampering leaves a detectable trace: the record's hash value changes, and the complete hash chain breaks.65% similarUnverifiedHash chains provide tamper detection rather than tamper prevention, and typically still need to be combined with append-only storage or external witness mechanisms.63% similarUnverifiedA frozendict is hashable on the premise that all its keys and values are themselves hashable; if it contains mutable values such as lists, construction and hashing will still fail.62% similar
