Erlay
Network● Common

A proposed transaction relay protocol using set reconciliation to reduce bandwidth by ~40%. Instead of announcing all transactions to all peers, nodes periodically reconcile transaction sets, sending only differences.

Technical Notes

Uses Minisketch for efficient set reconciliation. Hybrid approach: flood to some peers (fast propagation), reconcile with others (efficiency). Reduces per-node bandwidth from O(peers × txs) toward O(txs). Enables more peer connections.
