The problem of Byzantine consensus has been key to designing secure
distributed systems. However, it is particularly difficult, mainly due to the
presence of Byzantine processes that act arbitrarily and the unknown message
delays in general networks.
Although it is well known that both safety and liveness are at risk as soon
as n/3 Byzantine processes fail, very few works attempted to characterize
precisely the faults that produce safety violations from the faults that
produce termination violations.
In this paper, …
