System Requirements

The Base archive node reached a size of 804GB by May 2, 2024

Base 🔵

Base is a secure, low-cost Ethereum L2 built on Optimism’s open-source OP Stack. In this guide, Optimism's op-erigon 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 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

Snapshots URL: https://snapshot.testinprod.io/

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://datadirs.testinprod.io/base-mainnet-db-14631082.zst"
#to return to previous screen and continue installation press 

Ctrl+a+d

Compile Op-node

Required Software Dependencies

Install go

sudo wget https://go.dev/dl/go1.21.6.linux-amd64.tar.gz && sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.21.6.linux-amd64.tar.gz && rm go1.21.6.linux-amd64.tar.gz

Install nvm

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

Download foundry

curl -L https://foundry.paradigm.xyz | bash

Install foundry

foundryup

source /root/.bashrc

Install node and yarn

nvm install 16 && npm install --global yarn && nvm use 16 && npm -g install pnpm

source /root/.bashrc

Check if go and all dependancies are installed

go version
nvm -v
npm -v
yarn -v
pnpm -v

Create directories

mkdir -p /root/github
mkdir -p /root/data/base/op-node
mkdir -p /root/data/base/op-erigon

Build op-node

cd /root/github/

git clone https://github.com/ethereum-optimism/optimism.git

cd optimism

git checkout v1.7.0

nvm install && npm install --global yarn && nvm use node && npm -g install pnpm

pnpm install

pnpm build

make op-node

#The binary is built at /root/github/optimism/op-node/bin/op-node

Create systemd service

You'll need your own synced Ethereum L1 RPC URL (e.g. Erigon) and L1 Consensus Layer Beacon endpoint (e.g. Lighthouse) in order to run Base

ls #to see the name of downloaded archive

zstd --decompress base-mainnet-db-14631082.zst -o mdbx.dat

#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-erigon data directoy:

mv mdbx.dat /root/data/erigon/datadir/chaindata/

Start op-erigon

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

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

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

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

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

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