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. --=20 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 --XxnP3vfVQL6HUXlF Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEkPnKPD7Je+ki35VexYjWPOQbl8EFAmTWO38ACgkQxYjWPOQb l8HAvwgAl7rgvJq+5cZCenntjwaa6lKnriNerZZ5G+kuwCbkhUS63bisLeNKhzu1 gRUHRnfLpJIWVaN2Qg0is5KmNl06Gz0MjAmlKEz/To2u9KfkvJL2kXRdMDhFOUeW Ku7UHc8ey02ASUJeguG2IFuOWAgKPSIubxJRCnffoDssy89Zm40fWfX8EE5cMMog 4fD8IZbziOGxJ0XDj43P8pkeHOoYhpYq+3I8FpV+DX7EtV8R0ZZ/SFB8QrSeg/jW 2422lUApKxB5LDdCOGl8j56cITyrbWyC4fHBH9kUMx5J075PXze/mcL+s6kyFCTB IrtySiue2WdsVGgPv7fsmiKpFz2yBg== =/lX4 -----END PGP SIGNATURE----- --XxnP3vfVQL6HUXlF--
