Byzantine Fault

Byzantine Fault

Last Updated: January 23, 2026

Byzantine Fault is a condition where a system's components may fail and provide incorrect or inconsistent information to others.

Byzantine Fault is a situation in distributed computing where system components may fail in arbitrary ways. This includes sending conflicting or incorrect information to different parts of the system. It can occur due to malicious attacks or unexpected errors. In the context of blockchain and crypto systems, Byzantine Fault Tolerance (BFT) is crucial. BFT ensures the network can reach consensus even if some nodes act incorrectly. This makes systems robust against failures and attacks, ensuring security and reliability in decentralized environments.
