Are there any plans to support bn128 elliptic curves? #3

The bls12_381 elliptic curve can be compiled in circom, but the circomlib that uses baby jubjub (e.g. eddsa) cannot be used because it is on bn128. Probably not even a hash function can be used.

Ok, thank you for your suggestion. In the near future, I will start to add support for bn curves and increase support for arkworks library 😸

Hi @atsupontio , im so excited to let you know that i have implemented the bn256 curve adapter, so we can verify the proof generated by the circom using bn128 ! :), next i will support it in substrate!
