10:01 < provoostenator> Weekend food for thought (cc sipa): what would a taproot mulitsig output descriptor look like? Is it safe to share xpub with cosigners?

10:03 < provoostenator> Musig style multisig I should add, tapscript with OP_CHECKSIGADD shouldn't be an issue.

10:04 < provoostenator> IIUC you can't know the musig receive address without nonce (commitments). In that case you'd have an output descriptor that can't produce an address without additional info.

10:05 < provoostenator> I guess that's no different than a descriptor without and xpub followed by hardened derivation.

10:14 < provoostenator> Oh wait, this is actually a non issue. There's no nonces involved in public key aggregation, only in signatures: https://github.com/bitcoinops/taproot-workshop/blob/master/1.2-musig.ipynb

10:15 < provoostenator> At least for n-of-n no design changes to output descriptors seem necessary.

13:56 < elichai2> god. `sync.h` is complex
