Run First Validator Node

Prerequisites

• ansible
• laconic-so

Generate mainnet genesis file

Run node

• Update run-first-validator-vars.yml with required values:

  • Use the mainnet genesis file generated in the previous step

  # Private key of the existing account in hex format (required for gentx)
  pvt_key: ""
  
  # Path to the generated mainnet genesis file
  genesis_file: "<path-to-generated-genesis-file>"
  
  # Optional
  cerc_chain_id: "laconic-mainnet"
  cerc_moniker: "MainnetNode"
  min_gas_price: 0.001
  cerc_loglevel: "info"
  key_name: "validator"
  

• Export the data directory and mainnet deployment directory as environment variables:

  # Parent directory where the deployment directory will live
  export DATA_DIRECTORY=
  
  # Set mainnet deployment directory
  # for eg: mainnet-laconicd-deployment
  export MAINNET_DEPLOYMENT_DIR=
  

• Run ansible playbook to submit the gentx and run the node:

  ansible-playbook -i localhost, -c local playbooks/first-validator/run-first-validator.yml
  

• Check logs to ensure that node is running:

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR logs laconicd -f
  

Publish Genesis File and Node Address

• Copy the genesis file to genesis folder:

  sudo cp $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/data/laconicd-data/config/genesis.json ./genesis/mainnet-genesis.json
  

• Get your node's address:

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'echo $(laconicd cometbft show-node-id)@YOUR_PUBLIC_IP_ADDRESS:26656'
  

• Add your node's address to node-addresses.yml

• Submit a PR with this genesis file and node address so that it is available to other validators
