Optimal algorithms for byzantine agreement

WebAug 17, 2024 · Our algorithms operate in a very strong fault model: we require self-stabilisation, i.e., the initial state of the system may be arbitrary, and there can be up to f< n/3 ongoing Byzantine faults, i.e., nodes that deviate from the protocol in an arbitrary manner. 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.
