aMACI operator

The aMACI operator service is a unique feature offered by the Dora Factory Anonymous MACI protocol (aMACI). Running an aMACI operator means that you will run and tally an aMACI round for a community, and validate the round with zero-knowledge proofs. From the protocol's frontend, users will be able to create aMACI rounds and select an aMACI operator.

Installation

npm install -g @dorafactory/maci-operator

Quick Start

Option 1: Run with Node.js (Traditional)

# 1. Initialize operator workspace
maci init ./my-operator

# 2. Configure the operator
cd my-operator
vim config.toml  # Edit configuration file

# 3. Set operator identity (first time only)
maci set-operator identity .
maci set-operator maciPubKey .

# 4. Start the operator
maci start .

Option 2: Run with Docker (Recommended)

# 1. Initialize operator workspace
maci init ./my-operator

# 2. Configure the operator
cd my-operator
vim config.toml  # Edit configuration file

# 3. Set operator identity (first time only)
maci set-operator identity .
maci set-operator maciPubKey .

# 4. Start with Docker Compose
docker-compose up -d

# 5. View logs
docker-compose logs -f

For detailed Docker deployment instructions, see DOCKER.md.

Available Commands

maci init <dir>                    # Initialize operator workspace
maci start <dir>                   # Start the operator
maci set-operator identity <dir>   # Set operator identity on-chain
maci set-operator maciPubKey <dir> # Set operator MACI public key on-chain
maci zkey download <dir>           # Download circuit files
maci --help                        # Show help

Configuration

After running maci init, edit config.toml to configure:

• rpcEndpoint - Chain RPC endpoint
• indexerEndpoint - GraphQL indexer endpoint
• registryContract - Registry contract address
• identity - Your operator identity
• mnemonic - Operator wallet mnemonic
• coordinatorPrivKey - MACI coordinator private key
• zkeyPath - Path to circuit files
