BabyJubJub elliptic curve implementation in Rust. Is a twisted edwards curve embedded in the curve of BN128.
BabyJubJub curve explanation: https://medium.com/zokrates/efficient-ecc-in-zksnarks-using-zokrates-bd9ae37b8186
Uses: - MiMC7 hash function: https://github.com/arnaucube/mimc-rs - Poseidon hash function https://github.com/arnaucube/poseidon-rs
Compatible with the BabyJubJub Go implementation from https://github.com/iden3/go-iden3-crypto
## Warning
Doing this in my free time to get familiar with Rust, do not use in production.
