Byzantine Robustness

Definition

Byzantine robustness describes the capacity of a distributed system, such as a blockchain, to continue operating correctly even when some of its components or participants exhibit arbitrary or malicious behavior. This characteristic is vital for maintaining network integrity and consensus despite the presence of faulty or adversarial nodes. Systems possessing this quality can achieve agreement on a single state, even with a minority of compromised actors. This property ensures data consistency and operational continuity under challenging conditions.
