Here's a 3 round musig agreed spend on signet:

Notice how the witness is exactly one 64 byte schnorr signature.

(Repo: very much a work in progress:

(To repeat earlier comment, this is just for fun, and not even close to being useful for more than education experiments.)

Very much a work in progress, but I'm able to make N of N (3-round) musig transactions on regtest now with this (comically unsafe and very rudimentary) code:

My plan is to make it possible for counterparties to include signature adaptors (that was my main goal, to show that that is now possible). The whole JIT x-only thing mentioned in a previous post has certainly made this a little more, uh, exciting, than I expected :)

Key and signature aggregation with #MuSig can bring cheaper and more private #Bitcoin transactions to the #LightningNetwork.

Comes out of taproot review but this summary of how difficult it is to get threshold multisig working (by Poelstra) just makes me think we're going to have to stick with the combinatorial n of n musigs (in taproot branches) approach, at least until someone figures this all out!
