laconicd-full-node

Instructions for running a laconicd testnet full node and joining as a validator

Prerequisites

• Minimum hardware requirements:

  RAM: 8-16GB
  Disk space: 200GB
  CPU: 2 cores
  

• Testnet genesis file (file or an URL) and peer node addresses

Setup

• Clone the stack repo:

  laconic-so fetch-stack git.vdb.to/cerc-io/testnet-laconicd-stack
  

• Clone required repositories:

  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node setup-repositories
  

• Build the container images:

  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node build-containers
  

  This should create the following docker images locally:

  • cerc/laconic2d

Create a deployment

• Create a spec file for the deployment:

  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node deploy init --output laconic-full-node-spec.yml
  

• Edit network in the spec file to map container ports to host ports as required:

  ...
  network:
    ports:
      laconicd:
        - '6060:6060'
        - '26657:26657'
        - '26656:26656'
        - '9473:9473'
        - '9090:9090'
        - '1317:1317'
  

• Create a deployment from the spec file:

  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node deploy create --spec-file  laconic-full-node-spec.yml --deployment-dir laconic-full-node-deployment
  

• Copy over the published testnet genesis file (.json) to data directory in deployment (laconic-full-node-deployment/data/laconicd-data/tmp):

  # Example
  mkdir -p laconic-full-node-deployment/data/laconicd-data/tmp
  cp genesis.json laconic-full-node-deployment/data/laconicd-data/tmp/genesis.json
  

Configuration

• Inside the deployment directory, open config.env file and set following env variables:

  # Comma separated list of nodes to keep persistent connections to
  # Example: "node-1-id@node-1-host:26656,node-2-id@node-2-host:26656"
  CERC_PEERS=""
  
  # Optional
  
  # A custom human readable name for this node (default: TestnetNode)
  CERC_MONIKER=
  
  # Network chain ID (default: laconic_9000-1)
  CERC_CHAIN_ID=
  
  # Output log level (default: info)
  CERC_LOGLEVEL=
  

Start the deployment

laconic-so deployment --dir laconic-full-node-deployment start

Check status

• To list down and monitor the running containers:

  # With status
  docker ps -a
  
  # Get laconicd container id in a variable
  LACONICD_CONTAINER_ID=$(docker ps --filter "name=laconicd" -q)
  
  # Check logs for laconicd container
  docker logs -f $LACONICD_CONTAINER_ID
  

• Check the sync status of your node:

  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd status | jq .sync_info"
  

Join as testnet validator

• Create / import a new key pair:

  # Create new keypair
  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd keys add <key-name>"
  
  # OR
  # Restore existing key with mnemonic seed phrase
  # You will be prompted to enter mnemonic seed
  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd keys add <key-name> --recover"
  
  # Query the keystore for your account's address
  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd keys show <key-name> -a"
  

• Request tokens from the testnet faucet for your account if required

• Check balance for your account:

  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd query bank balances <key-name>"
  

• Create required validator configuration:

  # Edit the staking amount and other fields as required
  docker exec -it $LACONICD_CONTAINER_ID bash -c 'cat <<EOF > <your-node-moniker>-validator.json
  {
    "pubkey": $(laconicd cometbft show-validator),
    "amount": "900000000photon",
    "moniker": "<your-node-moniker>",
    "commission-rate": "0.1",
    "commission-max-rate": "0.2",
    "commission-max-change-rate": "0.01",
    "min-self-delegation": "1"
  }
  EOF'
  

• Create a validator:

  docker exec -it $LACONICD_CONTAINER_ID bash -c 'laconicd tx staking create-validator <your-node-moniker>-validator.json \
  --fees 50photon \
  --chain-id=laconic_9000-1 \
  --from <key-name>'
  

• View staking validator details:

  docker exec -it $LACONICD_CONTAINER_ID bash -c "laconicd query staking validator <key-name>"
  

Clean up

• Stop all services running in the background:

  # Stop the docker containers
  laconic-so deployment --dir laconic-full-node-deployment stop
  

• To stop all services and also delete data:

  # Stop the docker containers
  laconic-so deployment --dir laconic-full-node-deployment stop --delete-volumes
  
  # Remove deployment directory (deployment will have to be recreated for a re-run)
  rm -r laconic-full-node-deployment
