Some big news for taprooty PSBTs!
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2023-October/021988.html
Hi All,
I've written up a BIP draft for MuSig2 PSBT fields. It can be viewed at
https://github.com/achow101/bips/blob/musig2-psbt/bip-musig2-psbt.mediawiki.
This is based on this gist from Sanket:
https://gist.github.com/sanket1729/4b525c6049f4d9e034d27368c49f28a6.
There are a few notable differences:
- The participant pubkeys field is keyed by only the aggregate xonly key
- Participant pubkeys are compressed pubkeys rather than xonly.
