Deploy a Godwoken Network by Using Godwoken-Kicker​

Godwoken-kicker is a one-line command to start a Godwoken network on Devnet. This deployment method helps developers deploy Ethereum contracts and quickly migrate Ethereum DApps to CKB Devnet in testing and development environments.

  • RPC URL: http://localhost:8024
  • Chain ID: 1024777

Godwoken-kicker provides a quick mode and a custom mode for deployment.

The quick mode is fast and simple. It executes the builds of all components from pre-built docker images.

Environment

  • Ubuntu 20.04 LTS

Prerequisites

Steps

  1. Clone the source of Godwoken-kicker.

    If it is already cloned, skip to the next step.

    $ git clone https://github.com/RetricSu/godwoken-kicker.git

  2. Initialize Godwoken-kicker.

    note

    Stop any running Godwoken network by using the make stop command before initializing Godwoken-kicker. 

    $ cd godwoken-kicker
    $ make init

    The make init command can be used in the following situations:

    • It is the first time to start the Godwoken network.
    • The deployment mode is changed.
    • The CKB chain data and all layer 1 related cache data are deleted.

  3. Start the Godwoken network.

    The make start command can be used to start the deployed Godwoken network. The make start-f command can be used to force deploy and start a new Godwoken network.

    $ make start
    note

    Do note that after running the make clean command, run make init again if a reboot is desired.

    Great! Checkout http://localhost:6100 to deploy contract!

  4. Set up an Ethereum wallet.

    In this example, a MetaMask (an Ethereum Wallet) wallet is set up for the deployment. Add the MetaMask extension in the browser (Firefox, Google Chrome, Brave or Microsoft Edge) and create an account for the wallet.

    If there is a MetaMask wallet ready to be used, skip to the next step directly.

  5. After the Godwoken network has been successfully launched, visit the website http://localhost:6100 and connect the MetaMask wallet by clicking the Connect Wallet button.

      RPC URL=http://localhost:8024
      CHAIN ID=1024777

  6. Deploy an ETH contract to the Godwoken network.

    1. Prepare and compile an ETH contract.

    2. Deposit 400 CKB to the ETH wallet on the ACCOUNTS page of the Godwoken network.
    3. Deploy the ETH contract that you have compiled on the CONTRACT page of the Godwoken network.

    Deployment complete
    note

    The tx_hash and data_hash will be used in the next step to configure the setup-config.json file.

  5. Prepare the following files under the /godwoken/deploy folder.

    • pk: The file stores the private key that is used to deploy Godwoken.

      Example:

      0xca02cc4b8e0e447e243204dd2e16a1692026bfdd4add502b203975999d3a6909

    • scripts-build.json: The file specifies the pre-built docker image of Godwoken and the repositories of the other components like godwoken_scripts, godwoken_polyjuice and clerkb.

      Example:

      ```json title="/godwoken/deploy/scripts-build.json"
      {
          "prebuild_image": "nervos/godwoken-prebuilds:v0.6.9-rc1",
          "repos": {
              "godwoken_scripts": "https://github.com/nervosnetwork/godwoken-scripts#master",
              "godwoken_polyjuice": "https://github.com/nervosnetwork/godwoken-polyjuice#main",
              "clerkb": "https://github.com/nervosnetwork/clerkb#v0.4.0"
          }
      } 
      ```

      For more information about the tags of the prebuild_image, see nervos/godwoken-prebuilds.

    • setup-config.json: The file provides configurations for the Rollup.

      • l1_sudt_script_type_hash: The data_hash of the deployed SUDT script.

      • tx_hash (under l1_sudt_cell_dep): The tx_hash of the deployed SUDT script.

      • cells_lock: cells_lock is used to unlock/upgrade Rollup scripts.

      • reward_lock: reward_lock is used to receive challenge rewards.

      • burn_lock: burn_lock is used to receive burned assets that can be unlocked.

        note

        The file must be configured with correct SUDT script to deposit SUDT successfully.

        Example:

        /godwoken/deploy/setup-config.json
        {
          "l1_sudt_script_type_hash": "0xfe2a574febac93ef4da8e716403be072e4703da736676107d68a5e31b682943f",
          "l1_sudt_cell_dep": {
            "dep_type": "code",
            "out_point": {
              "tx_hash": "0x07de15f8afbd4b55e5d11248f4cd9f5195c8d96f171af04e7f727042bb0643c6",
              "index": "0x0"
            }
          },
          "node_initial_ckb": 1200000,
          "cells_lock": {
            "code_hash": "0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8",
            "hash_type": "type",
            "args": "0x1eb6190f883e11a2a67bcfac9533b0a84f50ddfb"
          },
          "reward_lock": {
            "code_hash": "0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8",
            "hash_type": "type",
            "args": "0x1eb6190f883e11a2a67bcfac9533b0a84f50ddfb"
          },
          "burn_lock": {
            "code_hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
            "hash_type": "data",
            "args": "0x"
          }
        }

  1. Set up Godwoken nodes.

    To set up Godwoken nodes:

    $ cd godwoken
    $ RUST_LOG=info cargo +nightly run --bin gw-tools setup -n 2 -k deploy/pk --network devnet --scripts-build-config deploy/build-scripts.json -c deploy/setup-config.json

    This setup command compiles Godwoken scripts, deploys the scripts and layer 2 genesis blocks, and generates configuration files for the Godwoken nodes.

    The deployment requires approximately 10 minutes to complete depending on network connection.

    Output Example:

    ...
    2021-11-19T06:22:47Z INFO  gw_tools::deploy_genesis] tx_hash: 0x4ec4532a4b8c7d799ef30d36df413f1e4aa05402336a3df53b4f9afa5baf52cd
    [2021-11-19T06:22:47Z INFO  gw_tools::utils::transaction] waiting tx 4ec4532a4b8c7d799ef30d36df413f1e4aa05402336a3df53b4f9afa5baf52cd
    [2021-11-19T06:22:52Z INFO  gw_tools::utils::transaction] tx proposed
    [2021-11-19T06:22:57Z INFO  gw_tools::utils::transaction] tx commited
    [2021-11-19T06:22:57Z INFO  gw_tools::setup] Finish

  2. Configure the receiver lock.

    After the setup command is completed, a config.toml file is generated under /godwoken/output/node1 and /godwoken/output/node2, and a scripts-deploy-result.json file is generated under /godwoken/output.

    1. Download the config generator tool and generate the config.json file for the CKB chain.

      note

      The CKB node must be running when executing the generator to generate the config file.

      To generate the config.json file in the project root directory:

      $ ./lumos-config-generator-linux-amd64 config.json http://127.0.0.1:8114

    2. Assign a receiver lock in the node's config.toml file.

      The code_hash of the receiver lock is the CODE_HASH of the SECP256K1_BLAKE160 script from the config.json file.

      The args is the lock args of the deployment cells owner.

      Example:

      config.toml
      [block_producer.challenger_config.rewards_receiver_lock]
      code_hash = '0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8'
      hash_type = 'type'
      args = '0x1eb6190f883e11a2a67bcfac9533b0a84f50ddfb'

  3. Start the Godwoken nodes.

    note

    The default node mode is fullnode. It can be modified in config.toml to either readonly mode or test mode.

    If the two nodes need to be started within the same environment, manually modify the listening port number in the config.toml file for each node.

    Run the following command to start node1:

    $ RUST_LOG=info cargo +nightly run --bin godwoken run -c output/node1/config.toml

    If an error about the use of unstable library feature is encountered during the process, try the following commands to fix the issue:

    $ cargo install cargo-edit
    $ cargo upgrade --workspace num-bigint

  4. Set up Polyjuice.

    Clone the source of godwoken-examples. For more information, see godwoken-examples.

    $ git clone --recursive https://github.com/nervosnetwork/godwoken-examples

    Then, create an account on Polyjuice. It will take some time to build index for the first time. 

    $ cd godwoken-examples
    $ yarn && yarn run build-all
    # export SCRIPT_DEPLOY_RESULT_PATH=<Path to scripts-deploy-result.json>
    $ export SCRIPT_DEPLOY_RESULT_PATH=~/godwoken/deploy/scripts-deploy-result.json
    # export GODWOKEN_CONFIG_PATH=<Path to godwoken config.toml>
    $ export GODWOKEN_CONFIG_PATH=~/godwoken/deploy/node1/config.toml
    $ yarn run copy-configs
    # LUMOS_CONFIG_FILE=<Path to config.json> node ./packages/tools/lib/account-cli.js deposit -c 40000000000 -p <privkey>
    $ LUMOS_CONFIG_FILE=~/config.json node ./packages/tools/lib/account-cli.js deposit -c 40000000000 -p 0xca02cc4b8e0e447e243204dd2e16a1692026bfdd4add502b203975999d3a6909

    For more information about generating the Lumos config file for DEV chain, see Generate the config.json file for the DEV chain.

  5. Start the web3 server.

    1. Create a PostgreSQL instance.

      $ docker run --name postgres -e POSTGRES_USER=user -e POSTGRES_DB=godwoken -e POSTGRES_PASSWORD=mypassword -d -p 5432:5432 postgres

    2. Clone the source of godwoken-web3.

      $ git clone https://github.com/nervosnetwork/godwoken-web3

    3. Prepare the .env file under /godwoken-web3/packages/api-server.

      $ cd godwoken-web3
      $ cat > ./packages/api-server/.env <<EOF
      DATABASE_URL=postgres://user:mypassword@postgres:5432/godwoken
      GODWOKEN_JSON_RPC=http://godwoken:8119
      ETH_ACCOUNT_LOCK_HASH=<Eth Account Lock Code Hash>
      ROLLUP_TYPE_HASH=<Rollup Type Hash>
      PORT=8024
      CHAIN_ID=1024777
      CREATOR_ACCOUNT_ID=3
      DEFAULT_FROM_ADDRESS=0x1eb6190f883e11a2a67bcfac9533b0a84f50ddfb
      POLYJUICE_VALIDATOR_TYPE_HASH=<Polyjuice Validator Code Hash>
      L2_SUDT_VALIDATOR_SCRIPT_TYPE_HASH=<L2 Sudt Validator Code Hash>
      TRON_ACCOUNT_LOCK_HASH=<Tron Account Lock Code Hash>
      EOF

    4. Start the web3 server.

      To start the web3 server properly, make sure to clear the postgres database, and then run the migration SQL file to recreate the tables before running the server:

      $ yarn
      $ yarn run migrate:latest
      $ yarn run build:godwoken
      $ yarn run start
