Bitcoin developers propose removing explicit RBF signals to reduce on-chain fingerprinting

According to ChainCatcher, CoinDesk reports that Bitcoin developers are discussing removing explicit Replace-by-Fee (RBF) signaling from the Bitcoin Core wallet. Developer rkrux stated that since full-RBF has become a standard strategy, BIP 125 RBF signaling has become redundant and may leave unnecessary wallet on-chain fingerprints.

Community member Murch said that stopping the transmission of replaceability signals is not simply about eliminating “fingerprints”, because each sender still needs to choose a sequence number for each input; currently, about 75% of transactions use specific sequence numbers, mainly MAX-2. rkrux stated that the default input sequence number should adopt best practices more widely recognized by the wallet community.
