The total tx size is bigger than\n\u003e the OP_TRUE approach, but you don’t need to ask for any protocol\n\u003e change.\n\nNo, that would change the TXID, which we rely on for HTLC transactions.\n\n\u003e In long-term, I think the right way is to have a more flexible SIGHASH system to allow people to add more inputs and outputs easily.\n\nAgreed:\nhttps://lists.linuxfoundation.org/pipermail/bitcoin-dev/2018-April/015862.html\n\nBut in the long term we'll have Eltoo and SIGHASH_NOINPUT which both\nallow different solutions.\n\nCheers,\nRusty."}
