Stone-Prover-Cairo0-Verifier

Overview

This repository demonstrates how proofs generated by StoneProver can be verified using the Cairo0 verifier. It includes two submodules:

• cairo-lang
• stone-prover

Getting Started

Clone the Repository

To get started, clone this repository and initialize its submodules:

git clone https://github.com/Okm165/stone-prover-cairo0-verifier.git
cd stone-prover-cairo0-verifier
git submodule update --init --recursive

Install Cairo Lang

Install the Cairo language by executing the following commands:

cd cairo-lang
pip install --upgrade pip
zip -r cairo-lang-0.12.0.zip cairo-lang-0.12.0
pip install cairo-lang-0.12.0.zip
cd ../

Build Stone-Prover

Build the StoneProver tool using Docker:

cd stone-prover
docker build --tag prover .
container_id=$(docker create prover)
docker cp -L ${container_id}:/bin/cpu_air_prover ./e2e_test
docker cp -L ${container_id}:/bin/cpu_air_verifier ./e2e_test
cd ../

Usage

Generate Proof

To generate a proof, follow these steps:

cd stone-prover/e2e_test
cairo-compile fibonacci.cairo --output fibonacci_compiled.json --proof_mode
cairo-run \
    --program=fibonacci_compiled.json \
    --layout=starknet_with_keccak \
    --program_input=fibonacci_input.json \
    --air_public_input=fibonacci_public_input.json \
    --air_private_input=fibonacci_private_input.json \
    --trace_file=fibonacci_trace.json \
    --memory_file=fibonacci_memory.json \
    --print_output \
    --proof_mode
./cpu_air_prover \
    --out_file=fibonacci_proof.json \
    --private_input_file=fibonacci_private_input.json \
    --public_input_file=fibonacci_public_input.json \
    --prover_config_file=cpu_air_prover_config.json \
    --parameter_file=cpu_air_params.json \
    -generate_annotations
cd ../../

Verify Proof

To verify the generated proof, use the following steps:

cd cairo-lang
jq '{ proof: . }' ../stone-prover/e2e_test/fibonacci_proof.json > cairo_verifier_input.json
cairo-compile --cairo_path=./src src/starkware/cairo/cairo_verifier/layouts/all_cairo/cairo_verifier.cairo --output cairo_verifier.json --no_debug_info
cairo-run \
    --program=cairo_verifier.json \
    --layout=starknet_with_keccak \
    --program_input=cairo_verifier_input.json \
    --trace_file=cairo_verifier_trace.json \
    --memory_file=cairo_verifier_memory.json \
    --print_output
cd ../

Future Work and Enhancements

Version Compatibility:

An essential future direction is to ensure compatibility with newer versions of Cairo Lang and Cairo Verifier. This involves analyzing the changes between different versions and updating the repository to accommodate these changes.

Continuous Maintenance:

To remain a reliable reference, the repository will be regularly updated. This maintenance includes fixing bugs, improving documentation, and incorporating community feedback.
