ePrint Report: Sailfish: Towards Improving Latency of DAG-based BFT

Nibesh Shrestha, Aniket Kate, Kartik Nayak

Existing DAG-based BFT protocols exhibit long latency to commit decisions. The primary reason for such a long latency is having a leader every 2 or more “rounds”. Even under honest leaders, these protocols require two or more reliable broadcast (RBC) instances to commit the proposal submitted by the leader (leader vertex), and additional RBCs to commit other proposals (non-leader vertices). In this work, we present …
