Patching Sigma Generator creation #516

merged 4 commits into from Jul 15, 2019

commented Jul 14, 2019

A concern was brought up on the public verifiability of the randomness of g in the Sigma generator. While we aren't aware of how this can be exploited as there is no discrete log relationship between g and h, the team agreed that it was best practice to have the generation of g publicly verifiable.

This PR makes g as a hash of the base point of secp256k1 library.
