demo

Prerequisites

• ansible
• laconic-so
• tmkms
  • Install with softsign feature

    cargo install tmkms --features=softsign --version=0.14.0
    

• Install zstd using sudo apt install zstd
• testnet-state.zst (exported testnet state)
• LPS distribution Google spreadsheet URL or CSV file path

Steps

• In current working directory demo, keep exported testnet-state.zst file from prerequisites

• Fetch stack:

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

• Generate LPS lockup distribution JSON file

  ~/cerc/laconicd-stack/scripts/generate-lps-lock.sh -i "<lps-distribution-spreadsheet-url-or-file-path>" -d "~/cerc/laconicd-stack/data"
  

  • This will generate the distribution.json file

• Export current working directory

  export CWD=$(pwd)
  

• Extract the testnet-state JSON file

  zstd -dc $CWD/testnet-state.zst > $CWD/testnet-state.json
  
  # Remove zst folder
  rm -rf testnet-state.zst
  

• Set envs:

  export EXPORTED_STATE_PATH=$CWD/testnet-state.json
  export LPS_DISTRIBUTION_PATH=~/cerc/laconicd-stack/data/distribution.json
  
  # Test address that does not exist on testnet chain
  export EARLY_SUPPORTS_ACC_ADDR=laconic1gwytamfk3m5n0gsawh5vpwxkwd3vapmvzpp6nz
  

• Copy the example variables file:

  cp ~/cerc/laconicd-stack/playbooks/first-validator/first-validator-vars.example.yml ~/cerc/laconicd-stack/playbooks/first-validator/first-validator-vars.yml
  

• Run playbook to use exported state for generating mainnet genesis:

  ansible-playbook -v -i localhost, -c local ~/cerc/laconicd-stack/playbooks/first-validator/generate-genesis.yml -e "exported_state_path=$EXPORTED_STATE_PATH" -e "lps_distribution_path=$LPS_DISTRIBUTION_PATH" -e "early_supports_acc_address=$EARLY_SUPPORTS_ACC_ADDR"
  

• Genesis file will be generated in output directory along with a file specifying the staking amount

  # List files in output directory - genesis.json and staking-amount.json
  ls -l output
  

• Set env for key of account with balance in testnet:

  export FIRST_ACCOUNT_KEY=<KEY_OF_ACCOUNT_WITH_BALANCE_IN_TESTNET>
  

• Create and populate first-validator-vars.yml:

  cat > ~/cerc/laconicd-stack/playbooks/first-validator/first-validator-vars.yml << EOL
  # Use a private key of an existing account with balance in testnet
  pvt_key: $FIRST_ACCOUNT_KEY
  
  # Path to the generated mainnet genesis file
  # Use the absolute path of generated output directory in the previous steps
  genesis_file: "$CWD/output/genesis.json"
  
  # Path to staking-amount.json generated in previous steps
  staking_amount_file: "$CWD/output/staking-amount.json"
  
  # Set custom moniker for the node
  cerc_moniker: "LaconicMainnet"
  # Set desired key name
  key_name: "laconic-validator"
  
  cerc_chain_id: "laconic-mainnet"
  min_gas_price: 0.001
  cerc_loglevel: "info"
  key_name: "laconic-validator"
  EOL
  

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

  # Parent directory where the deployment directory will live
  export DATA_DIRECTORY=$CWD
  
  # Set mainnet deployment directory
  export MAINNET_DEPLOYMENT_DIR=mainnet-laconicd-deployment
  

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

  ansible-playbook -v -i localhost, -c local ~/cerc/laconicd-stack/playbooks/first-validator/setup-first-validator.yml
  

• Create tmks config directory for first validator node

  tmkms init ./tmkms-first-node
  

• Update the TMKMS configuration file ./tmkms-first-node/tmkms.toml:

  cat > ./tmkms-first-node/tmkms.toml << EOL
  [[chain]]
  id = "laconic-mainnet"
  key_format = { type = "cosmos-json", account_key_prefix = "laconicpub", consensus_key_prefix = "laconicvalconspub" }
  state_file = "$CWD/tmkms-first-node/state/priv_validator_state.json"
  
  [[validator]]
  chain_id = "laconic-mainnet"
  addr = "tcp://localhost:26659"
  secret_key = "$CWD/tmkms-first-node/secrets/kms-identity.key"
  protocol_version = "v0.34"
  reconnect = true
  
  [[providers.softsign]]
  key_type = "consensus"
  path = "$CWD/tmkms-first-node/secrets/priv_validator_key"
  chain_ids = ["laconic-mainnet"]
  EOL
  

• Import the private validator key into tmkms:

  tmkms softsign import $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/data/laconicd-data/config/priv_validator_key.json $CWD/tmkms-first-node/secrets/priv_validator_key
  

• Start TMKMS:

  tmkms start --config $CWD/tmkms-first-node/tmkms.toml
  

  • Expected example output:

     INFO tmkms::commands::start: tmkms 0.14.0 starting up...
     INFO tmkms::keyring: [keyring:softsign] added consensus Ed25519 key: {"@type":"/cosmos.crypto.ed25519.PubKey","key":"T24No1A1FmetNRVCOSg2G2XAKWh97oBXuELdAD6DFgw="}
     INFO tmkms::connection::tcp: KMS node ID: 7f5fd8dae8953e964e7e56edd4700f597ea0d45c
    ERROR tmkms::client: [laconic-mainnet@tcp://localhost:26659] I/O error: Connection refused (os error 111)
    

    NOTE: The errors dissapear once the laconicd node starts

  • Note the pubkey logged at start for comparing later with validator pubkey on chain

• In a new terminal export envs

  export CWD=$(pwd)
  export DATA_DIRECTORY=$CWD
  export MAINNET_DEPLOYMENT_DIR=mainnet-laconicd-deployment
  
  # Test address that does not exist on testnet chain
  export EARLY_SUPPORTS_ACC_ADDR=laconic1gwytamfk3m5n0gsawh5vpwxkwd3vapmvzpp6nz
  

• Enable TMKMS in the laconicd node configuration:

  echo "TMKMS_ENABLED=true" >> $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/config.env
  

• Remove the validator key from node deployment as it is no longer required

  rm $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/data/laconicd-data/config/priv_validator_key.json
  

• Run the first validator node

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR start
  

• Check logs to ensure that node is running:

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

  • The chain will start running after some time.

• Verify that validator and TMKMS pubkeys match

  • Get validator pubkey on chain

    # Check consensus_pubkey in output
    laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query staking validators -o json | jq .validators'
    

  • Compare it with the pubkey noted from logs in TMKMS

• Check bonds list to confirm that testnet state was transferred properly:

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query bond list'
  

• Check alps and alnt tokens total supply:

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query bank total-supply'
  

• Query the lps_lockup account and view distribution:

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query auth module-account lps_lockup'
  

• Query the lps_lockup and early supports accounts balances:

  lockup_account_address=$(laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd 'laconicd query auth module-account lps_lockup -o json | jq -r .account.value.base_account.address')
  
  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd "laconicd query bank balances $lockup_account_address"
  
  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd "laconicd query bank balances $EARLY_SUPPORTS_ACC_ADDR"
  

• Copy the genesis file to config folder:

  cp $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/data/laconicd-data/config/genesis.json ~/cerc/laconicd-stack/config/mainnet-genesis.json
  

• Copy the staking amount file to config folder:

  cp $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR/data/laconicd-data/tmp/staking-amount.json ~/cerc/laconicd-stack/config/staking-amount.json
  

• Copy the example variables file:

  cp ~/cerc/laconicd-stack/playbooks/validator/validator-vars.example.yml ~/cerc/laconicd-stack/playbooks/validator/validator-vars.yml
  

• Check first validator node address using:

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

• Update cerc_peers in ~/cerc/laconicd-stack/playbooks/validator/validator-vars.yml:

Create a multisig with both the validator accounts

• On opening the app, a prompt will be shown to add laconic network to you Keplr wallet. Click on Approve

• Go to home and click on I don't have a multisig

• Add the addresses of your validators as member 1 and member 2

• Set the threshold to 2 out of 2 members (Both the validators should sign the TX to broadcast it)

• Click on Submit and Create multisig

Create and sign transaction

• Add accounts in Keplr wallet for signing the transaction

  • Open Keplr wallet and click on the user icon in the top right corner

  • Click on Add wallet, then select Import an existing wallet and go to Use recovery phrase or private key

  • Select the Private key tab and then paste the private key of the validator account and click on import

  • Set a name for the wallet (used when connecting wallet to app for signing transaction) and click on next

  • Search for Laconic network and select it, then click on Save

  • Follow the above steps for the second validator account

• Send fund to the generated multisig address using Keplr

  • Open Keplr wallet and select the account from which you wish to transfer the funds to the multisig address

  • Search and laconic and select the network. Select Send and paste the multisig address and set amount to 0.000000000001 (1000000alnt)

• Go to home, paste your multisig address and click on Use this multisig

• You will see the multisig members and holdings for the address

• Click on Create new transaction and then click on Bank Send under Add New Msg

• Enter the recipient address ( Eg: laconic1n4wa366kh0zxndwyq3kkse9ulz9jv9xukx3hy4), amount to be transfered and memo (optional)

• Click on create transaction

• Go back to the multisig info page and scroll down to the Transactions section

• Click on Verify identity and connect the app to your validator account in the Keplr wallet

• After approving the connection, you will see the list of transactions created by your multisig

• Click on your transaction and under Choose wallet to sign, click on connect Keplr

• After connecting the wallet, click on Sign transaction and approve the transaction

• Go back to multisig info page, switch to the second validator account in Keplr wallet and repeat the same process to sign the transaction with the second validator account

• Once the transaction is signed by both the validators, click on Broadcast Transaction

• Confirm funds transfer by checking balance of recipient address

  laconic-so deployment --dir $DATA_DIRECTORY/$MAINNET_DEPLOYMENT_DIR exec laconicd "laconicd query bank balances laconic1n4wa366kh0zxndwyq3kkse9ulz9jv9xukx3hy4"
