Definition ∞ Event log integrity refers to the assurance that records of actions and changes within a system, particularly a blockchain or distributed ledger, remain unaltered and trustworthy. On a blockchain, cryptographic hashing and immutability properties inherently contribute to this integrity, ensuring that once an event is recorded, it cannot be tampered with. This is fundamental for auditing, compliance, and maintaining trust in decentralized systems. It is a core security principle.
Context ∞ The discussion surrounding event log integrity is paramount in regulatory compliance and forensic analysis within the digital asset space. A critical future development involves enhancing the transparency and accessibility of on-chain event logs for auditors and regulatory bodies while preserving user privacy. Watching for advancements in verifiable computation and secure data storage solutions provides insight into strengthening the trustworthiness of digital records.
