The Base archive node reached a size of 13TB on November 30th, 2024

Base 🔵

Base is a secure, low-cost Ethereum L2 built on Optimism’s open-source OP Stack. In this guide, Optimism's op-geth and op-nodebinaries are built from source to facilitate the node's installation. This method has proved to sync an archive node successfully in ~48 hours using the official snapshot provided by the Base team.

Before you start, make sure that you have your own synced Ethereum L1 RPC URL (e.g. Erigon) and L1 Consensus Layer Beacon endpoint (e.g. Lighthouse) ready.

Pre-Requisites

sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y

sudo apt install -y git make wget aria2 gcc pkg-config libusb-1.0-0-dev libudev-dev jq gcc g++ curl libssl-dev screen apache2-utils build-essential pkg-config

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

Allow remote RPC connections with Base Node

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

Not advised to allow all or unknown IP address to RPC port

Enable Firewall

sudo ufw enable

Download a snapshot

Create a directory and start downloading an archive in screen session as it takes ~9 hours

mkdir base && cd base

screen -S archive

aria2c --file-allocation=none -c -x 10 -s 10 "https://base-snapshots-mainnet-archive.s3.amazonaws.com/$(curl https://base-snapshots-mainnet-archive.s3.amazonaws.com/latest)"
#to return to previous screen and continue installation press

If you wish to sync from scratch, consider bootstraping the node first by running

/root/github/op-geth/build/bin/geth --datadir /root/data/base/geth/op-geth init /root/data/base/geth/op-geth/genesis-l2.json

Sync using downloaded Snapshot

screen –r archive

ls #to see the name of downloaded archive

dtrx -f base-mainnet-archive-xxxxxx.tar.gz

#Unzipping takes ~3-4 hrs so you can go touch some grass

Consider switching screen by pressingctrl A+Dto allow a process run in the background

After extracting is done move the contents of geth directory into op-geth data directoy:

mv /root/base/snapshots/mainnet/download/geth/* /root/data/base/geth/op-geth/geth/

Start op-geth

sudo systemctl daemon-reload #refresh systemd configuration when changes made

sudo systemctl start op-geth.service #start op-geth

sudo systemctl enable op-geth.service #enable op-geth service at system startup

sudo journalctl -fu op-geth.service #follow logs of op-geth service

To check or modify op-geth.service parameters simply run

sudo nano /etc/systemd/system/op-geth.service

Ctrl+X and Y to save changes

You can also run curl command in the terminal to check the status of your node

curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false]}' \
  -H "Content-Type: application/json" http://localhost:8545

You can see If blocks increase at https://base.blockscout.com/ by entering returned hash. It means the node is catching up and the setup is successful.
