WebThe Byzantine Generals Problem Background. This problem was introduced by Leslie Lamport in his paper The Byzantine Generals Problem, where he describes the problem as follows: “Reliable computer systems must handle malfunctioning components that give conflicting information to different parts of the system. WebThe basic message of this paper should have been pretty obvious: the state machine approach, introduced in , allows us to turn any consensus algorithm into a general method for implementing distributed systems; the Byzantine generals algorithms of were fault-tolerant consensus algorithms; hence, we had fault-tolerant implementations of ...
