Building

git clone ...
git submodule update --init --recursive

Then (only once)

pip install toml # or any preferred of getting the dependency
python scripts/patch-midnight-ledger-prototype-with-local-deps.py

The script modifies the Cargo.toml files inside the submodule so that they use local paths to the other dependencies in there, instead of using url dependencies to the same monorepo. This is done to avoid running into compilation issues with duplicated git dependencies, and it also makes patching easier.

Local chain usage

1. Setup the local chain and fund the batcher.

cd ./local-chain-setup
source .envrc
npm install
docker compose up

2. Run the batcher.

cd ./local-chain-setup
cargo run --release

Whitelisting

The --allowed-contract flag has to be used to constrain the batcher to a single contract. The validation consists on checking that the deploy call has the smae operation names (exported circuits in compact) as the expected contract, and with the same verifier keys.

Example:

cargo run --release -- --allowed-contract ~/Work/pvp-arena/examples/pvp/contract/dist/managed/pvp/keys

NOTE: Compact doesn't remove old circuits from the keys directory (if circuits are renamed or deleted), and this will cause errors.
