## What Is the “Byzantine Generals Problem” That pBFT Aims to Solve?

The Byzantine Generals Problem is a thought experiment illustrating the difficulty of achieving consensus among decentralized parties where some may be malicious or unreliable (traitors). Practical Byzantine Fault Tolerance (pBFT) is a class of consensus algorithms designed to allow a network to function correctly and reach consensus even if a minority (typically less than one-third) of its nodes are faulty or malicious.

It ensures all honest nodes agree on the same state.
