Most relevant is that non-cooperative channel close transactions in Lightning use OP_CHECKSEQUENCEVERIFY, which references the sequence field of the txin; if the txin doesn't have a sequence number, OP_CHECKSEQUENCEVERIFY can't work. LockByBlock and LockByTime aren't described and there doesn't seem to be code for them in the PR (186). If there's a way to make OP_CLTV and OP_CSV work with this new format, please let us know, thanks! -Tadge --001a11402ef2e6a9ad053d0c4e44 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
