[v0.7.0] - 2022-03-25

Build

  • go.mod: go version upgrade 1.16 --> go1.17
  • update to gnark-crpto v0.7.0

Feat

  • adds gnark logger. closes #202
  • added internal/stats package: measure number of constraints of circuit snippets for regression
  • adds std/math/bits/ToNAF ToBinary ToTernary

Fix

  • enables recursive hints solving #293 and
  • move init() behind sync.Once. remove verbose option in stats binary
  • fixes #266 by adding constant path in Lookup2 and Select
  • incorrect handling of nbBits == 1 in api.ToBinary
  • PlonK vulnerability: thanks to Trail Of Bits for finding this vulnerability and responsibly disclosing it

Perf

  • restored frontend.WithCapacity option...
  • plonk: IsConstant -> ConstantValue
  • sw: no need for Lookup2 in constScalarMul
  • remove offset shifts in plonk compile
  • remove post-compile offset id in R1CS builder

Refactor

  • frontend.Compile now takes a builder instead of backendID as parameter
  • std/signature/eddsa Verify api now takes explicit hash and curve objects
  • make nboutputs of a hint explicit at compile time
  • std/pairing have more consistent apis
  • remove StaticHint wrapper, log duplicate hints (#289)
  • backend.WithOutput -> backend.WithCircuitLogger
  • remove all internal circuits from stats, keep important snippets only
  • frontend: split compiler, api and builder interface into interfaces
  • remove IsBoolean from R1CS variables
  • moved internal/compiled to frontend/compiled
