Progress Metrics in DAG-based Consensus
Abstract
Lachesis protocol~lachesis2021 leverages a DAG of events to allow nodes to reach fast consensus of events. This work introduces DAG progress metrics to drive the nodes to emit new events more effectively. With these metrics, nodes can select event timing and can choose previous events as parents for their own new events. Our results show that our event timing and parent selection methods can help reaching consensus quicker and thus can reduce lower time to finality significantly.
