# laconicd-full-node

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

## Prerequisites

* Minimum hardware requirements:

  ```bash
  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:

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

* Clone required repositories:

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

* Build the container images:

  ```bash
  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:

  ```bash
  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:

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

* Create a deployment from the spec file:

  ```bash
  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`):

  ```bash
  # 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:

  ```bash
  # 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

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

## Check status

* To list down and monitor the running containers:

  ```bash
  # With status
  docker ps -a

  # Follow logs for laconicd container
  laconic-so deployment --dir laconic-full-node-deployment logs laconicd -f
  ```

* Check the sync status of your node:

  ```bash
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd status | jq .sync_info"

  # `catching_up: false` indicates that node is completely synced
  ```

## Join as testnet validator

* Create / import a new key pair:

  ```bash
  # Create new keypair
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd keys add <key-name>"

  # OR
  # Restore existing key with mnemonic seed phrase
  # You will be prompted to enter mnemonic seed
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd keys add <key-name> --recover"

  # Query the keystore for your account's address
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd keys show <key-name> -a"
  ```

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

* Check balance for your account:

  ```bash
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd query bank balances <key-name>"
  ```

* Create required validator configuration:

  ```bash
  # Edit the staking amount and other fields as required
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd '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:

  ```bash
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd 'laconicd tx staking create-validator <your-node-moniker>-validator.json \
  --fees 50photon \
  --chain-id=laconic_9000-1 \
  --from <key-name>'
  ```

* View your staking validator details:

  ```bash
  laconic-so deployment --dir laconic-full-node-deployment exec laconicd "laconicd query staking validator <key-name>"
  ```

## Clean up

* Stop all services running in the background:

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

* To stop all services and also delete data:

  ```bash
  # 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
  ```
