Semaphore V4 - Circuits

Usage

Once you are in circom folder:

1. Install Circom and SnarkJS
2. Install the NPM dependencies with yarn
3. Run yarn run:ceremony to compile the circuit and run a fake trusted-setup for testing
4. Run yarn start to generate and verify Semaphore v3 and v4 proofs and compare them

Benchmarks

The difference between version 3 and 4 is in this case mainly due to the different version of SnarkJS. Benchmarks were run on a Intel Core i7-1165G7, 16 GB RAM machine.
