16:18 < roasbeef> vincenzopalazzo: yeh looks like a nice change 
16:20 < roasbeef> BlueMatt[m]: re nonces just for co-op close, idk does require implementations to wrangle with diff sig types for the same output, and arguably having _more_ spending paths makes it more complex 
16:20 < roasbeef> I think maybe ppl are overestimating the handling needed, it all fit pretty nicely into piggy backing on all the existing messages 
16:22 < roasbeef> also if we can make force closing less expensive on chain, then why not? a diff of like 64 bytes vs 200 something in witness size
16:25 < roasbeef> also correct re not having to persist nonces either
16:26 < roasbeef> to get a feel, this is where all the new nonce stuff for us lives, was able to encapsulate in a single place vs needing to sort of infect everything else: https://github.com/lightningnetwork/lnd/blob/simple-taproot-chans-channel-statemachine/lnwallet/musig_session.go
16:28 < roasbeef> instagibbs: I think you're missing another sig there? 
16:45 < BlueMatt[m]> Yea it’s not a ton of complexity, but it’s totally separate code paths for us to force close vs coop close (I don’t think it is for y’all?) so different script paths is not even a consideration
17:25 < instagibbs> Nonce persistance is really the only thing that bothers me.  I've implemented musig for unilateral closes for ln-symmetry and it was pretty natural as you say.  I just never had to implement nonce serialization, so I was staying firmly within the guard rails. 
17:26 < instagibbs> roasbeef I definitely could be missing a sig, but I think I'm right? one keyspend sig vs two scriptpaths, hence "one additional"
