The Byzantine Generals Problem defines a consensus challenge in distributed systems where decentralized nodes must agree on a single action despite the presence of faulty or malicious participants who send conflicting information. The theoretical solution requires protocols capable of reaching agreement if and only if fewer than one-third (for pure message-passing algorithms) or half (for cryptographic blockchains) of the system components are adversaries, ensuring that honest majority strategies override inconsistent inputs from traitors. This concept is fundamental to distributed computing theory underpinning fault-tolerant systems such as large-scale databases and blockchain protocols used for decentralized consensus without centralized authority.
