Abstract
The present disclosure is directed to a leader-based partially synchronous BFT SMR protocol that improves upon existing protocols by exhibiting two rounds of communication latency, linear authenticator complexity, and optimistic responsiveness. This is achieved through the novel use of an aggregate signature scheme as part of the protocol's view-change procedure.
