Fault Resilience

Definition ∞ Fault resilience refers to the capacity of a system, particularly a distributed ledger or blockchain network, to continue operating correctly even when individual components fail. It ensures that the system remains functional and accessible despite the occurrence of errors or malfunctions. This property is crucial for maintaining the reliability of decentralized applications and networks.
Context ∞ Fault resilience is a principal consideration in the design and evaluation of blockchain protocols, especially in discussions about consensus mechanisms and network stability. Debates often center on the trade-offs between different resilience strategies and their impact on performance and security.
