halo2aggregator-s

Aggregator for halo2 plonk circuits, including:

1. Provide aggregation circuit for target circuit verification.
2. Provide solidity code for aggregation circuit verification.

Prerequisite

1. truffle

Try it on local testnet

cargo test test_solidity_render --release -- --nocapture

In terminal 1:

cd sol
yarn
yarn start

In terminal 2:

cd sol
truffle test

Try it on Goerli

cargo test test_solidity_render --release -- --nocapture

cd sol
yarn

# add INFURA_PROJECT_ID, MNEMONIC in .env file

# NOTICE!!! This command would spend about 0.025 GoerliETH for deployment
# This command is a liitle bit slow in my test env, please wait for several minutes
truffle test --goerli

Use as lib

The solidity code generation depends on the sol folder. You can download it from source code or release according to the version.

1. call run_circuit_unsafe_full_pass() for target circuit with TranscriptHash::Poseidon to get aggregation circuit and its instances.
2. call run_circuit_unsafe_full_pass() for aggregation circuit with TranscriptHash::Sha or TranscriptHash::Keccak to create aggregation circuit proof.
3. call solidity_render() with TranscriptHash::Sha or TranscriptHash::Keccak to generate solidity code.
4. call solidity_aux_gen() to prepare aux input for solidity verify. It will prepare scalar division result used by the verification to reduce gas.

See test test_solidity_render for sample.
