WebThe Byzantine vector consensus (BVC) problem (also called multidimensional consensus) was introduced by Mendes and Herlihy [14] and Vaidya and Garg [19]. Tight bounds on number of processes n for Byzantine vector consensus have been obtained for synchronous [19] and asyn-chronous [14, 19] systems both, when the network is a … WebByzantine agreement by introducing approximate Byzantine agreement, allowing machines to reach approximate consensus rather than exact consensus. This was motivated by the fact that exact consensus in asynchronous systems was proven to be impossible [5]. Additionally, in synchronous systems, approximate Byzantine consensus can be used …
