WebThe Byzantine agreement problem is to devise an algorithm so that nprocessors, each with a private input can agree on a single common output that is equal to some processor’s input. For example, if all processors start with 1, they must all decide on 1. The processors should successfully terminate despite the presence of t= ( n) bad processors.
