What you're describing sounds like zero confirmation transactions which bitcoin used to support before RBF. You can't reliably take zero-conf in btc anymore though. So you have to wait for settlement to turn over goods or services.
- xorcist 9y agoZero conf was never secure. Many did demonstrate double spends long before RBF was thought of. Still, that argument was made against RBF and was enough of a hindrade to consensus that RBF was made opt-in. And it still is. So you are absolutely free to accept zero conf transactions, and take the risk, as long as you don't accept those who flag for RBF. Most wallets won't even make them by default (which in my opinion is stupid with the fees we have today). The argument for a golden age before RBF isn't a good one. It was never reliable. And what little reliability it had is unchanged.
