Security Audit Failure

Definition ∞ A security audit failure refers to an instance where vulnerabilities or critical flaws in a blockchain protocol or smart contract are discovered after a security audit has been completed and deemed successful. This indicates that the audit process failed to identify existing weaknesses, potentially leaving the system exposed to exploits. Such failures can severely compromise the integrity and safety of digital assets.
Context ∞ Security audit failures represent a significant risk to the credibility and safety of decentralized finance and blockchain projects. The discussion often centers on improving audit methodologies, increasing the depth of code review, and incorporating formal verification techniques. The industry continues to seek more robust and comprehensive auditing standards to minimize these critical oversights.
