Pub/Sub Dissemination on the XRP Ledger

Abstract

The XRP Ledger is one of the oldest and most well-established blockchains, using a particular type of consensus mechanism that differs from the typical Proof of Work and Proof of Stake. The underlying p2p network uses flooding to dis-seminate certain types of messages during the consensus rounds, leading to performance and scalability issues. In this work, we propose the use of publisher/subscriber dissemination on the XRPL using GossipSub to diminish the message overhead. We use Flexi-pipe, a tool that allows integration between the XRPL validator and GossipSub, to evaluate the improvements brought.
