CORE DEFINITION

The ability of a system to reach consensus in the presence of malicious nodes (Byzantine nodes). The system must be able to tolerate up to one-third of nodes being malicious.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Consensus mechanism in adversarial environments. In organizational management, when there are intentional saboteurs, it is necessary to establish a decision-making mechanism that can tolerate a certain proportion of "bad actors." Completely eliminating malice is impossible; the key is to establish fault tolerance mechanisms.

Byzantine Fault Tolerance (BFT) refers to the ability of a system to reach consensus even when some nodes fail arbitrarily (including lying or acting maliciously), tolerating the worst-case traitor nodes. It is a core guarantee for blockchain and highly reliable systems.
