It goes as follows: there are a number of Byzantine generals … The Byzantine Generals’ Problem is one of the most well-known and classic problems faced by decentralized networks. As a result, Proof of Work solves the Byzantine Generals Problem as it achieves a majority agreement without any central authority, in spite of the presence of unknown/potentially untrustworthy parties and despite the network not being instantaneous. In essence, the Byzantine generals’ problem is an allegory in the field of computer science, which tells a story of two generals (there can be more than two generals) planning to attack an enemy city. This situation can lead to incorrect syndrome decoding. In a distributed network such as that of Bitcoin’s, all participants and nodes are essentially of equally hierarchy. The Byzantine Generals’ Problem. Program. eval(ez_write_tag([[580,400],'coincentral_com-medrectangle-4','ezslot_4',127,'0','0'])); The above dilemma isn’t necessarily limited to just two generals.
