Byzantine consensus vector

WebThe problem of obtaining Byzantine consensus was conceived and formalized by Robert Shostak, who dubbed it the interactive consistency problem.

WebAbstract: This paper proposes a stack of three Byzantine-resistant protocols aimed to be used in practical distributed systems: multi-valued consensus, vector consensus and atomic broadcast. These protocols are designed as successive transformations from one to another. The first protocol, multi-valued consensus, is implemented on top of a … WebAll the communication channels are reliable and FIFO (first-in-first-out). • We prove that in a synchronous system, n ≥ max(3f+ 1, (d+1) f+1) is necessary and sufficient for achieving Byzantine vector consensus. • In an asynchronous system, it is known that exact consensus is impossible in presence of faulty processes.
