Definition ∞ A negligible security error denotes a probability of system failure or compromise that is so infinitesimally small it is considered practically impossible to occur within a reasonable timeframe. This term is frequently used in cryptography to quantify the robustness of a security mechanism. It signifies a very high level of security assurance. This provides strong confidence.
Context ∞ In the design and analysis of blockchain protocols and smart contracts, achieving a negligible security error is a primary objective to protect digital assets and user data. While absolute security is unattainable, cryptographic systems strive for this level of resilience against known and anticipated attacks. News often highlights audits and formal verification efforts aimed at reducing security vulnerabilities to this minimal level.
