I thought I rescued inversion free non-batch verification for batchable schnorr. 03:31 <@gmaxwell> The idea was to use the non-determinstic advice trick for the sqrt. Verify X matches the jacobian X. Then compute X^3 + 7 which gives you y^2, now instead of taking the sqrt. square the projective y... 03:31 <@gmaxwell> except ... that destroys the sign, for the obvious reason. 07:59 -!- jtimon [~quassel@18.31.134.37.dynamic.jazztel.es] has quit [Remote host closed the connection] 08:28 -!- nullbyte [NSA@gateway/vpn/mullvad/x-oaxkfxjcbymiwtgw] has joined #secp256k1 08:44 -!- nullbyte [NSA@gateway/vpn/mullvad/x-oaxkfxjcbymiwtgw] has quit [Ping timeout: 256 seconds] 08:46 -!- nullbyte [NSA@gateway/vpn/mullvad/x-bbmrbgwiaoohuqzq] has joined #secp256k1 09:00 -!- nullbyte [NSA@gateway/vpn/mullvad/x-bbmrbgwiaoohuqzq] has quit [Ping timeout: 240 seconds] 09:02 -!- nullbyte [NSA@gateway/vpn/mullvad/x-djycmpixscakrxbt] has joined #secp256k1 09:21 -!- nullbyte [NSA@gateway/vpn/mullvad/x-djycmpixscakrxbt] has quit [Ping timeout: 272 seconds] 09:22 -!- nullbyte [NSA@gateway/vpn/mullvad/x-jrcoqkqraiggshfm] has joined #secp256k1 10:55 -!- nullbyte [NSA@gateway/vpn/mullvad/x-jrcoqkqraiggshfm] has quit [Ping timeout: 240 seconds] 11:02 -!- nullbyte [NSA@gateway/vpn/mullvad/x-vhdbpwgluafwnswi] has joined #secp256k1 11:28 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has quit [Ping timeout: 256 seconds] 11:31 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has joined #secp256k1 11:49 -!- nullbyte [NSA@gateway/vpn/mullvad/x-vhdbpwgluafwnswi] has quit [Quit: leaving] 12:29 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has quit [Read error: Connection reset by peer] 14:14 <@gmaxwell> I'm sure there must be a cheaper way to compute just the #@$@$@# sign of R.y. 14:23 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has joined #secp256k1 22:53 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has quit [Ping timeout: 256 seconds] 22:54 -!- wumpus [~quassel@pdpc/supporter/professional/wumpus] has joined #secp256k1
