# ==== Mock Data for Testing Ethereum Validator Node Setup ==== # These commands simulate a local testnet validator setup without using real ETH. # You can run them on a development machine to verify your node configuration. # 1. Create a local testnet directory mkdir ~/eth-testnet && cd ~/eth-testnet # 2. Generate dummy validator keys (no real ETH required) # Using Lighthouse for example: lighthouse account validator create \ --datadir ./validator-data \ --count 1 \ --network goerli \ --keystore-password testpassword # 3. Start a local execution client in dev mode (Geth) geth --dev --http --http.api eth,net,web3,personal \ --datadir ./execution-data \ --allow-insecure-unlock # 4. Start a local consensus client in test mode (Lighthouse) lighthouse bn \ --network goerli \ --execution-endpoint http://localhost:8545 \ --datadir ./beacon-data # 5. Start the validator client with the dummy keys lighthouse vc \ --network goerli \ --datadir ./validator-data \ --beacon-nodes http://localhost:5052 # ==== Ethereum Validator Node Setup Script (Ubuntu 22.04) ==== # 1. Update system sudo apt update && sudo apt upgrade -y # 2. Install Execution Client (Geth example) sudo add-apt-repository -y ppa:ethereum/ethereum sudo apt update sudo apt install geth -y # 3. Install Consensus Client (Lighthouse example) sudo apt install curl build-essential pkg-config libssl-dev git -y curl https://sh.rustup.rs -sSf | sh -s -- -y source $HOME/.cargo/env git clone https://github.com/sigp/lighthouse.git cd lighthouse make sudo make install cd .. # 4. Generate Validator Keys (Mainnet) # Visit https://launchpad.ethereum.org for official key generation and deposit process # Example (Goerli testnet): lighthouse account validator create \ --datadir /var/lib/ethereum/validator \ --count 1 \ --network goerli \ --keystore-password mypassword # 5. Start Execution Client nohup geth --syncmode=full --http --http.api eth,net,web3 \ --datadir /var/lib/ethereum/execution & # 6. Start Consensus Client nohup lighthouse bn \ --network mainnet \ --execution-endpoint http://localhost:8545 \ --datadir /var/lib/ethereum/beacon & # 7. Start Validator Client nohup lighthouse vc \ --network mainnet \ --datadir /var/lib/ethereum/validator \ --beacon-nodes http://localhost:5052 &
