starkjs

PIL compiler and Circom transpiler. The stark prover is starky.

Note: since powdr syntax has been imcompatible with original pil, the scripts is no longer supported, the breaking changes happens at issue #271.

Run Example

Arithmetization: Constraint Polynomial

export CIRCUIT=fib
npm run $CIRCUIT

will generate the PIL json, Commitment Polynomial file and Constant Polynomial file.

Bottom Layer: FRI Proof

export CIRCUIT=fib
RUST_LOG=debug ../target/release/eigen-zkit stark_prove -s ../starky/data/starkStruct.json.gl \
    -p /tmp/$CIRCUIT.pil.json \
    --o /tmp/$CIRCUIT.const \
    --m /tmp/$CIRCUIT.cm -c circuits/$CIRCUIT.verifier.circom --i circuits/$CIRCUIT.verifier.zkin.json

Recursive Layer: FRI Proof

export CIRCUIT=fib
RUST_LOG=debug ../target/release/eigen-zkit compile -p goldilocks -i circuits/$CIRCUIT.verifier.circom -l node_modules/pil-stark/circuits.gl --O2=full -o /tmp/

# Circom to Stark

Top Layer: Snark proof

export CIRCUIT=fib
bash -x ../test/test_fibonacci_verifier.sh

Snark proof aggregation

export CIRCUIT=fib
bash -x ../test/test_aggregation_verifier.sh
