+ +==Abstract== + +This BIP proposes a new Bitcoin transaction relay protocol by introducing new +signaling support, which can be further used by nodes to negotiate new transaction +relay mechanisms and policies. + +==Motivation== + +Historically, upgrades to the transaction relay protocols have been down by updating +the protocol version number, and upgraded peers expecting support for new p2p messages +processing or alteration in current processing of p2p messages from equivalently upgraded +peers. + +This upgrade mechanism raise issues if new processing of current p2p messages is sanctionned +by an upgraded peer at the peering level by a disconnection of the violating non-upgraded peers. +Non-upgraded peers and clients can see their transaction broadcast silently failing for a subset +of theirs opened connections. + +We can improve current upgrade mechanism of the transaction relay protocol by introducing a new +node service bit to signal support for a new v2 transaction relay protocol. Within this protocol, +nodes can negotiate new transaction relay mechanisms and policies. + +==Specification== + +Peers supporting the v2 transaction relay protocol signal support by adverstising +the 13th bit service flag in the addr p2p messages (`ADDR` and `ADDRV2`). + +==Backward compatibility== + +Older clients remain fully compatible and interoperable after this change. + +==Implementation== + +https://github.com/bitcoin/bitcoin/pull/30572 + +==Copyright== + +This BIP is licensed under the GPLv2.
