ZQ1 to ZQ2 conversion how-to

  • Log in: gcloud auth login --update-adc

  • download the latest testnet or mainnet persistence:

    • GCS mainnet persistence backup: gs://zq1-mainnet-persistence/persistence
    • GCS mainnet blockchain data: gs://- zq1-mainnet-persistence/blockchain-data
    • GCS testnet persistence backup: gs://- zq1-testnet-persistence/persistence
    • GCS testnet blockchain data: gs://- zq1-testnet-persistence/blockchain-data
    mkdir -p /my/dir/persistences/zq1
cd /my/dir/persistences/zq1
gsutil cp gs://zq1-<network>-persistence/persistence/<network-name>-<blocknum>.tar.gz .
gsutil cp gs://zq1-testnet-persistence/blockchain-data/<network-name>/<network-name>.tar.gz .

  • extract the persistence and the blockchain data:

  tar xf <network-name>-<blocknum>.tar.gz
  tar xf <network-name>.tar.gz

  rm -f <network-name>-<blocknum>.tar.gz <network-name>.tar.gz
  • create a sample configuration for the deployment tools. You only need the right chain-id (testnet: 33101, mainnet: 32769): Testnet example
  cd /my/dir/zq2

  cat > config.toml <<-EOF
p2p_port = 3333
bootstrap_address = [ "12D3KooWNYaasyfY1wFrSHga3WBdZkb7bGhQiUz9926bQvk4HQj2", "/ip4/10.40.5.16/tcp/3333" ]

[[nodes]]
eth_chain_id = 33101 # change the chain it for your conversion
allowed_timestamp_skew = { secs = 60, nanos = 0 }
data_dir = "/data"
consensus.consensus_timeout = { secs = 60, nanos = 0 }
consensus.genesis_accounts = [ ["0xcca93a2e1169caf02e515203d1539cc3f390890a", "1000000000000000000000000"] ]
EOF
  • run the conversion tool: (It's a long running task, so you might want run it on a cloud vm and ensure the session keeps running in case you got disconnected or/and want recover the session later. Use screen)
screen -a
export Z2_CONVERTER=true
z2 converter convert /my/dir/persistences/zq1 /my/dir/persistences/zq2 config.toml <secret key>

The secret key is for a single validator which will be assumed to have 64 ZIL staked, so that the network has a validator on startup.
