WebAardvark [7] is a BFT protocol based on PBFT [5], the practical BFT protocol presented by Castro and Liskov. An important principle in the robustness of Aardvark is the presence of regular changes of the primary replica. Each time the primary is changed, a new conﬁguration, called view,is started.
