Run a Sepolia node

This guide will help you get a Sepolia archive node up and running.

Prerequisites​

Docker is installed and running. Git is installed. As of 2023-06-21T16:59:11+00:00 a full archive node sync takes 207.3 GB with geth + lighthouse. Consult the hardware requirements of the execution + consensus clients you are using.

Steps​

Clone eth-docker​

git clone https://github.com/eth-educators/eth-docker
cd eth-docker

Enable archive mode​

First, copy default.env to .env:

cp default.env .env

Next, open the .env file in your preferred text editor and set:

ARCHIVE_NODE=true

Complete the eth-docker quickstart​

Check your connection​

You can do a simple curl command to check if the node is synced (change port from 8545 to whatever you have the execution client p2p port set to in your .env file):

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":0}' http://127.0.0.1:8545

Harden your network (optional)​

This is important especially if you ssh into machine or open ports to the internet (be careful about that). Here are some recommended resources:
