# Halt stage0 and start stage1

Once all the participants have completed their onboarding, stage0 laconicd chain can be halted and stage1 chain can be initialized and started

## Prerequisite

* A CSV having the subscribers (`subscribers.csv`) placed at `/srv/laconicd/csvs`

## Login

* Log in as `dev` user on the deployments VM

* All the deployments are placed in the `/srv` directory:

  ```bash
  cd /srv
  ```

## Map subscribers to participants

* Fetch updated scripts in testnet-laconicd-stack:

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

* List the participants on stage0:

  ```bash
  cd /src/laconicd
  
  laconic-so deployment --dir stage0-deployment exec laconicd "laconicd query onboarding list"
  ```

* Create a CSV with subscribers who have onboarded as participants:

  NOTE: The following script can be run locally (as it will use <https://laconicd.laconic.com> endpoint by default)

  * Clone this repo

    ```bash
    git clone git@git.vdb.to:cerc-io/testnet-laconicd-stack.git
    ```

  * Build

    ```bash
    # Change to scripts dir
    cd testnet-laconicd-stack/scripts

    # Install dependencies and build
    yarn && yarn build
    ```

  * Run script
    
    ```bash
    # subscribers.csv is the CSV from beehiv
    yarn map-subscribers-to-participants --subscribers-csv /path/to/subscribers.csv --output subscribed-participants.csv

    # This should create the CSV file at subscribed-participants.csv
    # The participants in CSV can be filtered further
    ```
  
  * Copy over the file to deployments VM
    
    ```bash
    scp ./subscribed-participants.csv dev@<deployments-server-hostname>:/srv/laconicd/csvs/subscribed-participants.csv
    ```

## Halt stage0

* Confirm the the currently running node is for stage0 chain:

  ```bash
  cd /srv/laconicd

  laconic-so deployment --dir stage0-deployment logs laconicd -f --tail 30
  ```

* Stop the stage0 deployment:

  ```bash
  laconic-so deployment --dir stage0-deployment stop
  ```

## Start stage1

* Fetch updated scripts in fixturenet-laconicd-stack:

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

* Rebuild laconicd container with `>=v0.1.7` to enable `slashing` module:

  ```bash
  # laconicd source
  cd ~/cerc/laconicd

  # Pull latest changes
  git pull

  # Confirm the latest commit hash
  git log

  # Rebuild the containers
  cd /srv/laconicd

  laconic-so --stack ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd build-containers --force-rebuild
  ```

* Use the scripts in fixturenet-laconicd-stack to generate genesis file for stage1 using CSV with subscribed participants with token allocations:

  ```bash
  cd /srv/laconicd

  # Set current working dir path in a variable
  DEPLOYMENTS_DIR=$(pwd)

  cd ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd

  # Generate the genesis file
  # Participant allocation: 1000000000000 (10^12)
  # Validator allocation:   2000000000000000 (10^15)
  # These amounts are used only if funding amount is not present in the input CSV
  ./scripts/generate-stage1-genesis-from-csv.sh /srv/laconicd/csvs/subscribed-participants.csv 1000000000000 2000000000000000

  # If you see the error "Error: genesis.json file already exists: /root/.laconicd/config/genesis.json",
  # remove the temporary data directory and try again
  sudo rm -rf stage1-genesis

  # Expected output:
  # Genesis file for stage1 written to output/genesis.json

  # Remove the temporary data directory
  sudo rm -rf stage1-genesis

  # Go back to the directory where deployments are created
  cd $DEPLOYMENTS_DIR
  ```

* Copy over the generated genesis file (`.json`) containing the onboarding module state with funded participants to data directory in stage1 deployment (`stage1-deployment/data/genesis-config`):

  ```bash
  cd /srv/laconicd

  cp ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd/output/genesis.json stage1-deployment/data/genesis-config/genesis.json
  ```

* Start the stage1 deployment:

  ```bash
  laconic-so deployment --dir stage1-deployment start
  ```

* Check status of stage1 laconicd:

  ```bash
  # List down the container and check health status
  docker ps -a | grep laconicd

  # Follow logs for laconicd container, check that new blocks are getting created
  laconic-so deployment --dir stage1-deployment logs laconicd -f
  ```

* Query the list of registered participants in stage1 laconicd:

  ```bash
  laconic-so deployment --dir stage1-deployment exec laconicd "laconicd query onboarding list"

  # Confirm that all onboarded participants on stage0 appear in the list
  ```

* Get the node's peer adddress and stage1 genesis file to share with the participants:

  * Get the node id:

    ```bash
    echo $(laconic-so deployment --dir stage1-deployment exec laconicd "laconicd cometbft show-node-id")@laconicd.laconic.com:26656
    ```

  * Get the genesis file:

    ```bash
    scp dev@<deployments-server-hostname>:/srv/laconicd/stage1-deployment/data/laconicd-data/config/genesis.json </path/to/local/directory>
    ```
