babyjubjub-rs

BabyJubJub elliptic curve implementation in Rust. A twisted edwards curve embedded in the curve of BN128/BN256.

BabyJubJub curve explanation: https://medium.com/zokrates/efficient-ecc-in-zksnarks-using-zokrates-bd9ae37b8186

Uses:

Poseidon hash function https://github.com/arnaucube/poseidon-rs

Compatible with the BabyJubJub implementations in:

Go, from https://github.com/iden3/go-iden3-crypto
circom & javascript, from https://github.com/iden3/circomlib

Warning

Doing this in my free time to get familiar with Rust, do not use in production.
