| Jun 28, 2021 at 20:16 | comment | added | Dave Scotese | I think that discussing a relationship between a transaction and an opcode ("CSV is a script level opcode that is used to lock the spending of a particular output of a transaction...") is misleading. I thought the script has no awareness of transactions, only of the specific UTXO that it's return value, if true/1, unlocks and which therefore makes the transaction to which it's an input valid. Ben Carman suggested nSequence apply to "at least one" rather than "the first" (input), and I thought "Why not use a bit or two in nSequence to identify what it applies to?" | |

@PieterWuille I always had the opinion that it was to prevent DoS attacks. Earlier, no minrelayfee was required and hence that allowed nodes to spam the network at no cost by just incrementing nSequence. BIP-125 actually brought the protocol that the fees should be higher than the previously relayed transaction.

I believe that was the original reason for removing it, long before the mempool got an actual bounded size. | |
