The ability of a system to continue operating correctly and reach consensus even if some participants make mistakes, send false information, or act maliciously. The system remains secure as long as malicious or faulty participants make up less than one-third of the total number.
In blockchains, Byzantine fault tolerance is achieved through consensus mechanisms: nodes verify one another and reach agreement without needing to trust each other directly. This allows the system to function correctly even when some participants provide conflicting or false information.
The term “Byzantine” comes from the Byzantine Generals Problem. This is a logical problem in which several generals surrounding a city must decide together whether to attack or retreat. They communicate through messengers, but some generals or messengers may be traitors or deliver false information.
