Denial of service attack against final Byzantine fault tolerant systems

Most classical Byzantine fault tolerant system prefers finality on the consensus based on a voting algorithm that might not scale as good as stochastic finality. With other worlds, these systems prefer consistency over availability in case of network separation. It means, however, that the best denial of service attack against such a systems is the network separation, like separating the nodes in 60 - 40 %. In such case , the consensus mechanism simply stops.
