Byzantine Generals Problem

The Byzantine Generals Problem is a metaphor for ensuring reliable communication in a system where some participants might act maliciously or send false information. Imagine generals planning to attack a fortress; they must coordinate and agree on a common plan. However, some generals may betray or give false signals. The challenge is how to reach a consensus despite this interference. It highlights the difficulty of secure, trustworthy decision-making in distributed systems, such as computer networks, where ensuring all honest parties agree and coordinate correctly, even if some are dishonest, is crucial.
