322020-08-25T18:27:04 <roconnor> In taproot do I understand correctly? that the sighash modes of 0x00 and 0x01 are identical (beyond the fact that the sign the specific sighash flag)
332020-08-25T18:44:58 <luke-jr> roconnor: 00 is omitted in the signature too
342020-08-25T18:45:06 <luke-jr> which I'm thinking is a design flaw we should undo
352020-08-25T18:45:28 <luke-jr> aj (IIRC) argued that it reduces weight due to reduced complexity to verify, but I'm not sure it does :/
362020-08-25T18:46:47 <roconnor> luke-jr: That doesn't sound right. The hash_type is always included as the first byte in SigMsg even if it is 0x00.
372020-08-25T18:47:09 <roconnor> Oh right you mean in the signature itself. yes it is ommitted there.
382020-08-25T18:47:24 <roconnor> and if you use hash_type 0x01 then it is included.
392020-08-25T19:59:38 *** reallll is now known as belcher
402020-08-25T20:28:16 <roconnor> What would be the hypothetical path to adding SigHashNoInput to segwit v1? It would involve a new pubkey key type?
