zk-toolkit

Library built from scratch to implement zk-protocols.

Goal

To build a zk library from scratch keeping the implementation as easily understadable as possible so that it can help people including myself who are studying zk technology understand lower level details of it.

What's implemented so far

Basic operations in field calculation (add, sub, mul, inv, pow, sq)
Weierstrass type elliptic curve add and scalar mul operations in affine/jacobian coordinates
ECDSA sign and verify
SHA256 hasher

What's NOT implemented so far

Big number
Random number generation
