There is= + a dedicated purpose for pre-SegWit, SegWit, multisigs =E2=80=94 and now a = +purpose for Schnorr sigs/Taproot outputs is needed. That is why I brought f= +orward this proposal, which addresses exactly this need - and also will sup= +port at the same time multisigs and pre-Taproot outputs, making all previou= +sly used purpose fields redundant, simplifying future wallets. + +Kind regards, +Maxim + |
