Bitcoin Optech Newsletter #313 (9 min) The Bitcoin Core development team is discussing potential upgrades related to free relay and fee bumping. Free relay occurs when a full node relays unconfirmed transactions without a significant increase in fee revenue, potentially reducing the number of relay nodes and increasing centralization risks. Peter Todd proposed two forms of replace-by-feerate (RBFR) to mitigate transaction pinning attacks, but one criticism was that RBFR enables free relay. TRUC is another proposal, which doesn't depend on top-mempool feerates like RBFR does. A longer-term plan involves implementing the cluster mempool proposal, which would require disabling CPFP carve-out and changing how replace-by-fee works, potentially affecting Lightning Network software that uses anchor outputs to protect money in payment channels. The discussion also covers various types of attacks related to free relay and possible solutions for them.
