Anon-Aadhaar Protocol Implementation in Noir

This project implements the Anon-Aadhaar protocol using Noir.

[!WARNING] It is not safe to use in production with real data. Please use the Circom implementation for production use.

Modules

• /circuits: Noir Circuits
• /js: js sdk for proving noir circuits
• /scripts: Scripts for testing and benchmarking

Setup

Prerequisites

Note: Ensure you have Noir version 0.38.0 and barretenberg backend verison 0.61.0

installed and . If not, set it specific version using the following command:

noirup -v 0.36.0
bbup -v 0.61.0

Build circuits:

cd circuits
nargo compile

Testing

To run the tests:

nargo test --show-output

Testing with Real Data

To run the tests with read data:

1. Setup scripts:

cd scripts
yarn install

2. Configure environment:

   • Create .env in scripts directory with:

export REAL_DATA=true
export QR_DATA= <aadhar data (bigint)>

3. Generate test inputs:

yarn gen-test-inputs

This creates test inputs in circuits/testcases/test.toml

4. Execute tests with real data:

nargo execute -p testcases/test.toml

Benchmarks

Benchmarks via the Barretenberg Backend on M1 Macbook Pro 2020:

To run the benchmarks:

cd scripts
./benchmark.sh
