Tool to use signature with baby_jubjub curve

This repository contains zksnark constarint systems for twisted edwards curve point addition, point multiplication, eddsa signature verification and pedersen commitments. As well as python scripts for test case generation.

This is a naive implmentaion and considerable optimizations are possible.

docker run -ti --name ubuntu -v /<fullpath>/baby_jubjub_ecc:/code ubuntu:16.04 /bin/bash
cd /code
apt update && apt install -y build-essential cmake git libgmp3-dev libprocps4-dev python-markdown libboost-all-dev libssl-dev pkg-config
git submodule update --init --recursive
mkdir build && cd build
cmake .. && make

Start your preferred ethereum node, cd tests and run python3 test* will generate all the test variables that you can confirm in src/main.cpp

You can run the test after building by

cd build
./src/main

Lecture 16 and [Lecture 17] (https://www.youtube.com/watch?v=zTt4gvuQ6sY) of this course should help you get a good understanding of the basics of what we are doing here.
