Definition ∞ Data integrity failure describes an event where data becomes corrupted, inconsistent, or inaccurate. In blockchain systems, this can compromise the reliability of transactions or smart contract operations. Such failures undermine trust in the immutability and security of distributed ledgers. They can result from software bugs, malicious attacks, or external data discrepancies.
Context ∞ Reports of data integrity failures often appear in news related to blockchain exploits or oracle vulnerabilities. The industry continually works on enhancing cryptographic proofs and consensus mechanisms to prevent such occurrences. Maintaining data integrity is fundamental to the trustworthiness of decentralized applications.
