The Blocklace: A Partially-Ordered Generalization of the Blockchain
Introducing the blocklace, a partially ordered generalization of the totally ordered blockchain. In this presentation, Ehud Shapiro (Weizmann Institute of Science) shows how the blocklace can realize all algorithmic tasks required for ordering consensus: dissemination, equivocation-exclusion, and ordering. These capabilities are integrated in Cordial Miners – a family of efficient Byzantine Atomic Broadcast (permissioned blockchain consensus) protocols, with optimal instances for the models of asynchrony and eventual synchrony. Their efficiency – almost half the latency of state-of-the-art DAG-based protocols – stems from their use of the blocklace not only for ordering, as DAG-based protocols do, but also for dissemination and equivocation exclusion.
