There was a problem hiding this comment.
The other groups uses big-endian so perhaps we should also do it here also, but the groth16 api expects little-endian representations, so it's not entirely consistent. Any opinions on this?

Implementation of GroupElement + Pairing for the BN254 curve construction.
Under the hood it's wrapping Arkworks' implementation from the
ark_bn254crate. This is already used elsewhere, eg. in zkLogin.
