System Requirements
2TB+ op-erigon
3.5TB+ l2geth (legacy)
Op-erigon reached a size of 1.6TB by Sep 2, 2024
L2-geth is 3.4TB
Optimism 🔵
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.
To serve pre-bedrock eth_calls, you will also need an l2geth (legacy) node. Instructions for how to set up an l2geth node can be found in
Pre-Requisites
Copy 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
Copy sudo ufw default deny incoming
sudo ufw default allow outgoing Allow SSH
Copy sudo ufw allow 22/tcp Allow remote RPC connections with Optimism Node
Copy 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
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
Copy mkdir Optimism && cd Optimism
screen -S archive
