The backout transaction might not be timelocked itself, but can depend on another timelocked transaction (made specifically to avoid the backout transaction be timelocked). That extra transaction will need to be broadcast before the backout transaction. To account for that possibility, takers would need to either use more relaxed verification rules (do not check if the inputs of the 'snitch transaction' exist), or would need to check the whole package of dependent transactions in which the last one spends the bond. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
