+ BIP: XXX + Layer: Peer Services + Title: Transaction Relay V2 + Author: Antoine Riard+ +==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, nodes have been exchanging transactions on the Bitcoin peer-to-peer +network by sending an inv, and if the transaction has not been discovered and processed +yet by the other peer, sending a dedicated tx message. + +Sending an unnannounced tx message has always been considered in conformity with +the protocol, however this behavior creates a denanonymization vector if leveraged +by mass connectors. + +We can eliminate this concern by using node service bits 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.+ Comments-Summary: No comments yet. + Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0339 + Status: Draft + Type: Standards Track + Created: 2024-09-05 + License: GPLv2 +
