The problem of obtaining Byzantine consensus was conceived and formalized by Robert Shostak, who dubbed it the interactive consistency problem. This work was done in 1978 in the context of the NASA-sponsored SIFT project in the Computer Science Lab at SRI International. SIFT (for Software Implemented Fault Tolerance) was the brain child of John Wensley, and was based on the idea of using multiple general-purpose computers that would communicate through pairwis… Webal. [13]. Along with it, they also proposed a Byzantine fault-tolerant consensus algorithm (DLS), which, although ineﬃcient, proved that the problem has a solution in partially synchronous systems. The PBFT algorithm was the ﬁrst to provide a correct solution for state machine replication with Byzantine faults in a partially syn- gemalto active x
