DISK

8 vCPU

Ubuntu 22.04

16 GB

1 TB (SSD)

The node has a size of 585 GB as of March 14th, 2025.

Pre-requisite

Before starting, clean the setup then update and upgrade. Install following:

Git
Go v1.23+
rustc
make
just
op-node
op-reth
jq
Ethereum Sepolia L1 RPC URL
L1 Consensus Layer Beacon URL

Before you start, make sure that you have your own synced `Ethereum Sepolia L1 RPC URL` (Ethereum not base ) & `L1 Consensus Layer Beacon endpoint` (e.g. Lighthouse Sepolia) ready.

Installation Command

sudo apt update -y && sudo apt upgrade -y && sudo apt auto-remove -y
sudo apt install -y git make just wget gcc pkg-config libusb-1.0-0-dev libudev-dev jq gcc g++ curl libssl-dev screen apache2-utils build-essential pkg-config

Install Rustc

curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh # Follow the prompt instruction 
rustc --version #Verifying the installation

Install Op-node

git clone https://github.com/ethereum-optimism/optimism.git
cd optimism/op-node
just VERSION=v1.12.1 op-node # build op-node
cp ./bin/op-node /usr/bin #Placing op-node binary in /usr/bin
op-node -v #Verify version

Install Op-reth

git clone https://github.com/paradigmxyz/reth.git
cd reth
make build-op # build op-reth must install/upgrade dependencies
cp ./target/release/op-reth /usr/bin #Placing op-reth binary in /usr/bin
op-reth -V # Verify Version

Setting up Firewall

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow SSH

sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443
sudo ufw allow 8545
sudo ufw allow 5052

Allow Remote connection

sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545

Enable Firewall

sudo ufw enable

Setup Instructions

Cloning Base node repository

git clone https://github.com/base/node.git
mv node /mnt/base-sepolia
