- BIP360 rewrite
With Bitcoin Core 29.0, full-RBF is now enabled by default and the mempoolfullrbf setting has been removed. Any transaction in the mempool can now be replaced regardless of BIP125 signaling, fundamentally changing the security model for zero-confirmation transaction acceptance.
- Double-spend attacks now trivial for any user with RBF-capable wallet
- Research shows wallets without RBF checks amplify retail double-spend risk
- User Experience Issues: Protocol-unaware users may not understand that unconfirmed funds aren't actually "theirs yet," leading to accidental double-spends when trying to "speed up" transactions
- Security Model Breakdown: Zero-conf risk analysis changes from "susceptible to miner attacks" to "anyone can attack with easy-to-use wallet interfaces"
- Network Fragmentation: As full-RBF adoption spread, previously reliable zero-conf acceptance policies became unpredictably unreliable
