Definition ∞ Event Integrity refers to the assurance that a recorded event on a blockchain is accurate, unaltered, and corresponds precisely to its actual occurrence. This property confirms that data, once committed to the distributed ledger, remains verifiable and resistant to modification or corruption. It is a fundamental principle underpinning the trustworthiness of blockchain technology. Maintaining event integrity is paramount for auditability and reliability.
Context ∞ Discussions about event integrity are prevalent in news concerning supply chain tracking, digital identity, and verifiable credentials built on blockchain. Any report of a security breach or data manipulation within a decentralized application directly questions the event integrity of its underlying records. The robustness of cryptographic hashing and consensus mechanisms are frequently examined in this context, highlighting their role in preserving data authenticity.
