A fork of the BLS12-381 pairing-friendly elliptic curve construction crate, adding target group serialization. This fork exists because the upstream maintainers do not wish to merge the proposed serialization standard (zkcrypto/bls12_381#12). The crate tracks upstream with the gt-serialisation branch merged.

In the PostGuard ecosystem, pg-curve is the lowest-level building block. The ibe crate depends on it for all BLS12-381 curve arithmetic.

Development

Build the crate with all features:

cargo build --all-features

Run tests:

cargo test

Releasing
