Legendary Bitcoin developer Peter Todd has <a href="https://x.com/peterktodd/status/1820562457015779355" rel="noopener noreferrer nofollow">announced</a> that full replace-by-fee (full-RBF) has become the default in Bitcoin Core v28.0.&nbsp;
The RBF feature allows replacing unconfirmed Bitcoin transactions with different transactions that offer higher fees. It is generally used for fee bumping, cancelation, or updating transactions.&nbsp;
While&nbsp;BIP-125 allows disabling RBF, full-RBF makes sure that transactions are always replaceable.&nbsp;
The debates about full-RBF have been raging within the Bitcoin community for more than a decade. Bitcoin is known for being extremely conservative when it comes to implementing significant changes.&nbsp;
Todd also <a href="https://petertodd.org/2023/why-you-should-run-mempoolfullrbf#full-rbf-peering" rel="noopener noreferrer nofollow">argues</a> that the transaction is good for miners due to profit-maximizing. Moreover, such a feature reduces legal risks that might arise from unconfirmed double-spends. When it comes to security, full-RBF eliminates the risk of an attacker pulling off a double-spend by slowing down propagation.&nbsp;
Finally, full-RBF also increases privacy by making it more challenging for blockchain sleuths like Chainalysis to deanonymize transactions.&nbsp;
According to Todd, it took full-RBF peering as well as a lot of marketing on his side in order to finally integrate the feature:&nbsp;
“I think the #1 thing it took was forking Bitcoin Core for years with full-RBF peering code; #2 being token protocols accidentally creating an auction market paying thousands of dollars in fees to full-RBF miners.” He added that the revenue opportunity offered by the feature would have likely remained unnoticed without full-RBF peering. &nbsp;
