It was written in terms of normal transactions, but can be extended to mess= age signing transactions too. https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-March/018615.h= tml Only the beginning of the post is relevant here. - Ali On Wed, Aug 10, 2022 at 11:11:10PM +0000, Ryan Grant wrote: > >> TODO: A way for the initial signer to delegate to another > >> scriptPubKey; needed for better privacy and CoinJoin/Lightning > >> compatibility > > I need more documentation to understand this motivation. > > On Tue, Aug 9, 2022 at 8:46 PM Ali Sherief via bitcoin-dev > wrote: > > In the case of the last TODO, related to delegation to another > > scriptPubKey, I am not quite sure at the moment what to do about > > it - perhaps you guys can place a MAST (two Merkle branches, to be > > specific) - the first branch has the original signer's scriptPubKey, > > the second branch contains the delegated signer's scriptPubKey. > > I don't understand this requirement, but it seems that whatever > parties are involved can make signatures on the delegating and > delegated keys.
