IntroductionWhat is a Fuel Node? A Fuel node on the blockchain, or “client”, is software that downloads and maintains a copy of the blockchain. It verifies the authenticity of each block and transaction, ensuring that its copy is always up-to-date and synchronized with the network. Consensus Mechanism The Fuel Network uses Proof of Authority (PoA) in its beta testnets.Validators: Selected entities responsible for creating blocks and validating transactions based on their reputation.Advantages of PoA: Fast transaction times and energy efficiency.Node InstallationPreparing the EnvironmentUpgrade Packagessudo apt-get update && sudo apt-get upgrade -y Install wget and curlInstall rustupcurl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ | sh Installing Fuel ToolchainInstall Fuel Toolchaincurl https://install.fuel.network | sh Update Environmentsource /home/(user)/.bashrc Check Fuel Versionfuelup --version Verify Installation Ensure you have the latest toolchain:fuelup show Obtaining a Sepolia API Key (Ethereum Testnet)Register on Alchemy Get your personalized Sepolia ETH RPC API keys: https://www.alchemy.com/ Test the API Send the first request to test the API:curl https://eth-mainnet.g.alchemy.com/v2/AvlIDj-8eJlcz2NfOK1iMbR5iK1MnAtO \ -X POST -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"alchemy_getAssetTransfers","params":[{"fromBlock":"0x0","category":["external","erc20","erc721"],"fromAddress":"0x646d3C0367f91c6sCcf7532A91Ef425BEcdfB34E"}],"id":0}' Generating a New P2P KeyRun Keygenfuel-core-keygen new --key-type peering Chain ConfigurationCreate Configuration Foldergit clone https://github.com/FuelLabs/chain-configuration chain-configuration mkdir .fuel-sepolia-testnet cp -r chain-configuration/ignition/* ~/.fuel-sepolia-testnet/ Node Initialization and StartStart the Nodefuel-core run \ --service-name=<your_node>-sepolia-testnet-node \ --keypair <P2P key> \ --relayer https://eth-sepolia.g.alchemy.com/v2/<ETH RPC API> \ --ip=0.0.0.0 --port=4000 --peering-port=30333 \ --db-path ~/.fuel-sepolia-testnet \ --snapshot ~/.fuel-sepolia-testnet \ --utxo-validation --poa-instant false --enable-p2p \ --reserved-nodes /dns4/p2p-testnet.fuel.network/tcp/30333/p2p/16Uiu2HAmDxoChB7AheKNvCVpD4PHJwuDGn8rifMBEHmEynGHvHrf \ --sync-header-batch-size 100 \ --enable-relayer \ --relayer-v2-listening-contracts=0x01855B78C1f8868DE70e84507ec735983bf262dA \ --relayer-da-deploy-height=5827607 \ --relayer-log-page-size=500 \ --sync-block-stream-buffer-size 30 Creating a Service with SystemDSystemD facilitates automatic and reliable management of the Fuel node, improving operational stability and efficiency.Automation and SupervisionCreate the Servicesudo tee /etc/systemd/system/fueld.service > /dev/null << EOF [Unit] Description=Fuel Node Beta-5 After=network.target [Service] User=$USER Type=simple ExecStart=$(which fuel-core run) \ --service-name stonekeyboard-sepolia-testnet \ --keypair <P2P key> \ --relayer https://eth-sepolia.g.alchemy.com/v2/<ETH RPC API> \ --ip=0.0.0.0 --port=5000 --peering-port=40444 \ --db-path $HOME/.fuel-sepolia-testnet \ --snapshot $HOME/.fuel-sepolia-testnet \ --utxo-validation --poa-instant false --enable-p2p \ --reserved-nodes /dns4/p2p-testnet.fuel.network/tcp/30333/p2p/16Uiu2HAmDxoChB7AheKNvCVpD4PHJwuDGn8rifMBEHmEynGHvHrf \ --sync-header-batch-size 100 \ --enable-relayer \ --relayer-v2-listening-contracts=0x01855B78C1f8868DE70e84507ec735983bf262dA \ --relayer-da-deploy-height=5827607 \ --relayer-log-page-size=500 \ --sync-block-stream-buffer-size 30 Restart=on-failure LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF Reload and Start the Servicesudo systemctl daemon-reload sudo systemctl enable fueld sudo systemctl start fueld sudo systemctl status fueld.service View Logssudo journalctl -u fueld -f -o cat Connect Your Node to the Fuel WalletLog in to your Fuel wallet account and click on the top part where it indicates the network, then click on "+Add new network" and type in the address of your node: http://ip_node:4000/v1/graphql Click on "+Add" to complete the setup.
