Running a validator node in the Babylon project involves several steps: setting up the environment, configuring the node, and ensuring it runs efficiently. This guide provides detailed instructions to help you through the process.

Step 1: Setting Up the Environment

1. Update and Upgrade the System:

   bashCode kopiëren
   sudo apt update && sudo apt upgrade -y
   
   

2. Install Go:

   bashCode kopiëren
   wget <https://golang.org/dl/go1.17.6.linux-amd64.tar.gz>
   sudo tar -C /usr/local -xzf go1.17.6.linux-amd64.tar.gz
   echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile
   source ~/.profile
   
   

3. Install Required Packages:

   bashCode kopiëren
   sudo apt install build-essential jq -y
   
   

Step 2: Clone the Babylon Project Repository

1. Clone the Repository:

   bashCode kopiëren
   git clone <https://github.com/babylonchain/babylon.git>
   cd babylon
   
   

2. Build the Binary:

   bashCode kopiëren
   make install
   
   

Step 3: Configuration

1. Initialize the Node:

   bashCode kopiëren
   babylond init <your_node_name> --chain-id babylon-1
   
   

2. Download Genesis File:

   • Obtain the genesis file from the Babylon project and place it in the ~/.babylond/config directory:

     bashCode kopiëren
     wget <https://raw.githubusercontent.com/babylonchain/babylon/main/genesis.json> -O ~/.babylond/config/genesis.json
     
     

3. Configure the Node:

   • Open ~/.babylond/config/config.toml and set persistent_peers and seeds with peers from the Babylon network.

4. Configure Minimum Gas Prices:

   • Open ~/.babylond/config/app.toml and set minimum-gas-prices:

     tomlCode kopiëren
     minimum-gas-prices = "0.025ubbn"
     
     

5. Add Your Validator Key:

   bashCode kopiëren
   babylond keys add <your_validator_name> --keyring-backend os
   
   

Step 4: Running the Validator Node

1. Start the Node:

   bashCode kopiëren
   babylond start
   
   

2. Create a Validator:

   • After your node is synchronized, create a validator:

     bashCode kopiëren
     babylond tx staking create-validator \\
       --amount=1000000ubbn \\
       --pubkey=$(babylond tendermint show-validator) \\
       --moniker="<your_node_name>" \\
       --chain-id=babylon-1 \\
       --commission-rate="0.10" \\
       --commission-max-rate="0.20" \\
       --commission-max-change-rate="0.01" \\
       --min-self-delegation="1" \\
       --from=<your_validator_name> \\
       --keyring-backend=os
     
     

Step 5: Maintenance and Monitoring
