Base Node

Base is a secure, low-cost, developer-friendly Ethereum L2 built on Optimism's OP Stack. This repository contains Docker builds to run your own node on the Base network.

Quick Start

1. Ensure you have an Ethereum L1 full node RPC available

2. Choose your network:

   • For mainnet: Use .env.mainnet
   • For testnet: Use .env.sepolia

3. Configure your L1 endpoints in the appropriate .env file:

   OP_NODE_L1_ETH_RPC=<your-preferred-l1-rpc>
   OP_NODE_L1_BEACON=<your-preferred-l1-beacon>
   OP_NODE_L1_BEACON_ARCHIVER=<your-preferred-l1-beacon-archiver>
   

4. Start the node:

   # For mainnet (default):
   docker compose up --build
   
   # For testnet:
   NETWORK_ENV=.env.sepolia docker compose up --build
   
   # To use a specific client (optional):
   CLIENT=reth docker compose up --build
   
   # For testnet with a specific client:
   NETWORK_ENV=.env.sepolia CLIENT=reth docker compose up --build
   

Supported Clients

• geth (default)
• reth
• nethermind

Requirements

Minimum Requirements

• Modern Multicore CPU
• 32GB RAM (64GB Recommended)
• NVMe SSD drive
• Storage: (2 * current chain size + snapshot size + 20% buffer (to accommodate future growth)
• Docker and Docker Compose

Production Hardware Specifications

The following are the hardware specifications we use in production:

Geth Full Node

• Instance: AWS i4i.12xlarge
• Storage: RAID 0 of all local NVMe drives (/dev/nvme*)
• Filesystem: ext4

Reth Archive Node

• Instance: AWS i7ie.6xlarge
• Storage: RAID 0 of all local NVMe drives (/dev/nvme*)
• Filesystem: ext4

[!NOTE] To run the node using a supported client, you can use the following command: CLIENT=supported_client docker compose up --build

Supported clients:

• geth
• reth (with Flashblocks support option, see Reth Node README)
• nethermind
