replace-by-fee

According to BeInCrypto, a Bitcoin user paid a fee of 1.6 BTC (approximately $102,800) in block 962,142 due to an automated script going out of control, while the actual transfer amount was zero. The automated script run by the user enabled the Replace-by-Fee (RBF) feature, automatically increasing the fee bid every second, ultimately depleting the entire balance in the wallet.The mining pool SpiderPool mined this block and reaped this unexpected profit, with the fee accounting for 88% of the total fees for that block (approximately 1.82 BTC).

According to CoinDesk, Bitcoin developers are discussing the removal of the explicit Replace-by-Fee (RBF) signal from the Bitcoin Core wallet. Developer rkrux stated that since full-RBF has become the standard strategy, the BIP 125 RBF signal has become redundant and may leave unnecessary wallet chain fingerprints.Community member Murch noted that stopping the sending of replaceability signals is not simply about removing "fingerprints," as each sender still has to choose a sequence number for each input; currently, about 75% of transactions have used specific sequence numbers, primarily MAX-2. rkrux indicated that the default input sequence number should adopt best practices recognized by a broader wallet community.
