With unforgeable written messages, the problem is solvable for any number of generals and possible traitors . Applications of the solutions to reliable computer systems are then discussed.

In 2008, Satoshi Nakamoto essentially solved the infamous computational issue called the “Byzantine generals’ problem” or the “Byzantine Fault.” Throughout the history of man, people used ledgers to record economic transactions and property ownership.

Attacks where adversaries have full control of a number of . authenticated devices and behave arbitrarily to disrupt the . network are referred to as Byzantine attacks [3].Once the active. set of insider nodes in the network are turned to be malicious by. the attackers then the whole network will be under the control.

Byzantine fault tolerance is 50% assuming zero network latency. It is around 46% (Ethereum) and 49.5% (Bitcoin) fault tolerant under actually observed conditions, but it goes down to 33% if network latency is equal to the block time and reduces to zero as network latency approaches infinity.24 Oca 2020
