“It’s Bitcoin Core v25.0, with Antoine Riard’s full-rbf peering code, and some additional minor updates to it.”This does two things for full-rbf nodes:
1) Advertises a FULL_RBF service bit when mempoolfullrbf=1 is set.
2) Connects to four additional FULL_RBF peers.
“Doing this ensures that a core group of nodes are reliably propagating full-rbf replacements. We don’t need everyone to run this. But it’d be helpful if more people did.””Full-rbf peering advertises the fact that you’ve done this with a service bit, and ensures you are connected to at least four other nodes also advertising that bit. Basically full-rbf peering ensures that txs propagate well,” Todd wrote on Stacker.news.The developer also shared a link to his blog post where he provides a detailed rationale on why more people should run full-rbf.
