12019-12-10T00:16:56  <ZmnSCPxj> t-bast-official: With non-32-byte SegWit v1 we *could* support a Taproot-like construction where the keypath spend has tagged pubkeys.
  22019-12-10T00:17:44  <ZmnSCPxj> t-bast-official: But as you noted, this loses privacy, as it is now explicit output tagging as it allows anyone to see the enablement of `SIGHASH_NOINPUT`

 302019-12-10T10:49:17  <ZmnSCPxj> The annex currently has absolutely no format other than starting with 0x50, I guess to maximize the possible future extensibility of the annex?

 572019-12-10T16:41:00  <pinheadmz> sipa: what is the source of the secp256k1 commits that were squashed in sipa/taproot?
 582019-12-10T16:41:03  <pinheadmz> for example: 0a3a7f9b6c Add xonly_pubkeys which are serialized as 32 byte and whose Y coordinate is a quadratic residue
 592019-12-10T16:41:38  <pinheadmz> I can't find the original commit in either bitcoin-core/secp256k1 or ElementsProject/secp256k1-zkp

 662019-12-10T18:18:28  <pinheadmz> ty :-)
 672019-12-10T18:22:07  <pinheadmz> nickler: actually, still not sure exactly where they are. See here:
 682019-12-10T18:22:08  <pinheadmz> https://github.com/sipa/bitcoin/commit/d5cd9db7a3d71d55c4eb7f9170e0ae1cde12390e
 692019-12-10T18:22:27  <pinheadmz> 0c774d89e6 Merge bitcoin#688: Fix ASM setting in travis <-- last commit from bitcoin-core/secp256k1
 702019-12-10T18:23:26  <pinheadmz> 12 or so commits on top of that one I'm trying to find
 712019-12-10T18:23:59  <nickler> The "Fix ASM settings" commit is in libsecp master. Which one exactly are you looking for?
 722019-12-10T18:24:22  <pinheadmz> correct, all the commits on top
 732019-12-10T18:24:27  <pinheadmz> 0a3a7f9b6c Add xonly_pubkeys which are serialized as 32 byte and whose Y coordinate is a quadratic residue
 742019-12-10T18:24:31  <pinheadmz> through
 752019-12-10T18:24:34  <pinheadmz> c86c6cff66 Fixup rename
 762019-12-10T18:30:44  <nickler> pinheadmz: https://github.com/jonasnick/secp256k1/commits/schnorrsig-backup38 should have the exact same commits (except "Fixup rename")
 772019-12-10T18:31:16  <pinheadmz> a ha!!! ok thanks :-)
 782019-12-10T18:32:28  <nickler> would have accounted for them better if I had known that they would be useful to someone
 792019-12-10T18:33:59  <pinheadmz> no worries, and I know nothings final yet either. We vendor secp in bcoin, but its already been pulled in and used for other schnorr projects with 33 byte pubkeys etc. So Im trying to figure out how best to support "both versions" of schnorr. being able to track git branches is helpful
