... To respond to these challenges, uBFT introduces a new abstraction called Consistent Tail Broadcast (CTBcast) that we use to prevent equivocation [58], while requiring a practically bounded amount of memory. 1 Equivocation-a major source of problems in a system with Byzantine failures [22]-occurs when a faulty process incorrectly sends different information to different processes, which may cause the state of replicas to diverge. CTBcast prevents equivocation for all messages, but only ensures the delivery of the last broadcast messages, where is a parameter that trades memory for latency (we explain how to set it in Section 7). ...

... Extensive literature exists on consensus and primary-backup consensus, with numerous studies (e.g., [5,6,8,10,12,13,15,20,26,31,38,49,54,55,64,68,69,74,79,86]) focused on reducing communication costs and enhancing the performance and resilience of consensus systems [16,17,34,37,39,40,42,48,50,57,66,70,73,76,85,87,87]. ...
