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:

  cd /srv
  

Map subscribers to participants

• Fetch updated scripts in testnet-laconicd-stack:

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

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

  # Change to scripts dir
  cd ~/cerc/testnet-laconicd-stack/scripts
  
  # Install dependencies and build
  yarn && yarn build
  
  # Run script
  yarn map-subscribers-to-participants --subscribers-csv /srv/laconicd/csvs/subscribers.csv --output /srv/laconicd/csvs/subscribed-participants.csv
  
  # This should create the CSV file at /srv/laconicd/csvs/subscribed-participants.csv
  

Halt stage0

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

  cd /srv/laconicd
  
  laconic-so deployment --dir stage0-deployment logs laconicd -f --tail 30
  

• List the participants on stage0:

  laconic-so deployment --dir stage0-deployment exec laconicd "laconicd query onboarding list"
  

• Stop the stage0 deployment:

  laconic-so deployment --dir stage0-deployment stop
  

Start stage1

• Fetch updated scripts in fixturenet-laconicd-stack:

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

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

  # 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:

  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):

  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:

  laconic-so deployment --dir stage1-deployment start
  

• Check status of stage1 laconicd:

  # 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:

  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:

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

  • Get the genesis file:

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

• Now users can follow the steps to Join as a validator on stage1
