new hash_types (not defined in bip-taproot) wouldn't fail the signature verification mentioned in bip-taproot? 02:49 -!- jonatack [~jon@p57B4C1A5.dip0.t-ipconnect.de] has quit [Ping timeout: 250

[~Lee@173-23-103-30.client.mchsi.com] has quit [Ping timeout: 250 seconds] 02:52 < cdecker> The other difference I see is related to the hashing: bip118 was blanking the elements that we don't want to commit to, but still adding them into the hash, your revision mentions not including the hash, does that mean we just don't update on those elements instead of passing in blanks of the same size? 02:54 -!- vtnerd [~Lee@173-23-103-30.client.mchsi.com] has joined #lightning-dev 02:56 < aj> cdecker: yep figured, just wanted to make sure it wasn't get spam filtered or anything 02:58 < aj> cdecker: bip-taproot only specifies key path signature verification, so shouldn't be possible for anything in that to fail 02:58 < cdecker> Oh, missed that detail, thanks for clarifying 02:59 < cdecker> It's getting hard to keep the contexts in mind when reading these things xD 02:59 < aj> cdecker: the key version bump uses the "unknown pubkey" path in bip-tapscript, so bip-tapscript doesn't do any validation (beyond assuming empty signature means a failing checksig) so we can make all the rules 02:59 < aj> cdecker: haha, it's always been hard :) 03:00 < cdecker> Awesome, that sounds like it can be deployed easily 03:00 < aj> "we just don't update on those elements" -- update the sha256 state when computing the digest? yeah i think that's right 03:01 < cdecker> Yeah, ok, that's a few computations fewer than my blank but still add :+1: 03:01 < aj> i think sipa might be changing how the digest is specified to be more unambiguous which might improve things, https://github.com/sipa/bips/issues/99 03:03 < cdecker> Hm, need to dig a bit deeper into that side of things :-) 03:06 < aj> cdecker: we're thinking about running a "taproot bip review" thing over nov-dec btw, which might be a good way for lightning peeps to get a more in depth look into things; https://docs.google.com/document/d/1G48-yhZMLLMZW68Bq59h_FBi__pwFKoWKF1D385I38Y/edit# has some thoughts on how it might work 03:07 < cdecker> Ok, got to go back to the talks, but thanks for the work you put into bip118, it looks great I think 03:07 -!- __gotcha [~Thunderbi@plone/gotcha] has
