Is there an official, or widely used, name for segwit v0? > As others have said, I think `is_segwit` should match all segwit versions. Pavol also sorta answered your "widely used name" question though he didn't draw attention to it -- segwit v0 outputs are called "p2wsh" or "p2wpkh". But I don't know any term that covers "p2wsh or p2wpkh but not p2tr". Other than "segwit_v0", which we are currently using, and which I agree is a bit of a mouthful. -- Andrew Poelstra Director of Research, Blockstream Email: apoelstra at wpsoftware.net Web: https://www.wpsoftware.net/andrew The sun is always shining in space -Justin Lewis-Webster
