Tamper-Proof Audit Trail

Definition

A tamper-proof audit trail is an unalterable, chronological record of all activities and transactions within a system, designed to prevent any unauthorized modification or deletion. In blockchain technology, the inherent immutability of the distributed ledger provides a robust foundation for such an audit trail. Each entry is cryptographically linked to the previous one, making any alteration immediately detectable. This ensures the integrity and reliability of historical data, which is critical for accountability and compliance.
