18:22 < elichai2> Hi, I'm looking for the origins of the pay-to-contract/sign-to-contract/adaptor-signatures ideas.
18:23 < elichai2> for pay-to-contract I found this: https://arxiv.org/abs/1212.3257 although I'm not quite sure about it (didn't read te whole paper yet). for s2c it seems that andytoshi came up with it but no good source for it. adaptor signatures there's Tadge's DLC tough it's not the exact same thing
18:24 < sipa> p2c was invented by timo hanke o think
18:28 < sipa> though iirc the original construction was broken
18:29 < sipa> s2c iirc was invented by greg maxwell
18:29 < sipa> by applying p2c to the nonce point in signatures
18:30 < elichai2> was s2c invented my greg or the anti nonce side channel usage of s2c?
18:30 < sipa> both i believe
18:31 < sipa> though the scheme andytoshi has been talking about lately may be a bit more advanced than the orignal idea
18:32 < sipa> adaptor signatures was by andytoshi
19:43 < elichai2> in secp, why in the code `secp256k1_gej_add_ge`&&`secp256k1_gej_set_infinity` is used instead of just using `secp256k1_gej_set_ge`?
19:50 < sipa> link?
20:05 < elichai2> sipa: right now i'm looking at it here: https://github.com/jonasnick/secp256k1/compare/schnorrsig-s2c-only-new...schnorrsig-s2c-only-new-ans#diff-313ca26f0048bc16a608709915d0111eR115
20:05 < elichai2> but I think I saw it another time in the past
20:07 < sipa> that seems unnecessary indeed
20:13 < elichai2> ha. ok, I thought that this might be some constant time trick i'm missing. Thanks!
20:21 < elichai2> nickler: am I missing something about this? I see that you do stuff like that all over your 3 PRs (At first I commented where I saw this but i'll stop because I see more of this heh)
