zkSNARK library suggestion

[gbotrel]

Hi all, very interesting project :)

I see you are using libsnark, and would like to suggest to have a look at our work: https://github.com/ConsenSys/gnark .

It is written in Go so should integrate with zkPoD stack well, and for your circuit, I suspect the performance of the prover will be significantly better.
