Fork Your Own Ergo Chain

Back to Testnet

Configuration

To start your custom Ergo chain, you need to modify the configuration to ensure it doesn't clash with the Ergo mainnet or public testnet. The key changes involve setting a unique addressPrefix and custom magicBytes.

Here’s an updated configuration for your testnet.conf file:

ergo {
  networkType = "testnet"

  node {
    mining = true
    offlineGeneration = true
    useExternalMiner = false
  }

  chain {
    addressPrefix = 32 #  to avoid address clashing with Ergo mainnet and public testnet
  }
}

scorex {
  network {
    magicBytes = [2, 0, 4, 8] # custom value to avoid connections with other networks
    bindAddress = "0.0.0.0:9022"
    nodeName = "ergo-testnet-5"
    #knownPeers = []
  }

  restApi {
    apiKeyHash = "324dcf027dd4a30a932c441f365a25e86b173defa4b8e58948253471b81b72cf"
  }
}

Steps to Run the Node

  1. Set Up the Configuration:

    Make sure your testnet.conf file is configured as shown above. This will help prevent address clashes with the mainnet and public testnet by using a custom addressPrefix and magicBytes.

  2. Compile the Node:

    Use the following command to compile the Ergo node:

    sbt assembly

    This will generate an ergo.jar file at /target/scala*/ergo-*.jar.

  3. Run the Node:

    Start the node using the command:

    java -jar -Xmx4G ergo-*.jar --testnet -c testnet.conf
  4. Initialize and Unlock the Wallet:

    Access the panel at 127.0.0.1:9052/panel to initialize and unlock your wallet. This is necessary as the first blocks will be generated using Autolykos v1.

This setup ensures your custom chain runs independently and avoids conflicts with existing networks.
