The Zora Mainnet archive node has a size of 693GB on October 10th, 2024

Zora

Zora operates within Optimism Superchain ecosystem and is built using the OP stack, leveraging the scalability and security of Optimism's Layer 2 infrastructure.

In this guide, we are walking through the process of setting up a Zora Mainnet archive node using Optimism's op-gethand op-node.

Before you start, make sure that you have your own synced Ethereum L1 RPC URL (e.g. Erigon) and L1 Consensus Layer Beacon endpoint with all historical blobs data (e.g. Lighthouse) ready. A beacon endpoint meeting this criteria is essential for syncing to start.

Hint: https://console.chainstack.com/user/account/create has a free plan enough to sync a node

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 Zora Node

sudo ufw allow from ${REMOTE.HOST.IP} to any port 8545 
sudo ufw allow from ${REMOTE.HOST.IP} to any port 7545

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

sudo ufw allow 9222
sudo ufw allow 30303

Enable Firewall

sudo ufw enable

To check the status of UFW and see the current rules

sudo ufw status verbose

Initialize op-geth

/root/zora/op-geth/build/bin/geth init --datadir=/root/data/zora/zora-op-geth --state.scheme hash /root/data/zora/zora-op-geth/genesis.json

Launch Zora

Start op-geth

It's usually simpler to begin with startingop-geth before you start op-node. You can start op-geth even if op-node isn't running yet, but op-geth won't get any blocks until op-node starts.

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

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

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

sudo nano /etc/systemd/system/zora-op-geth.service #make changes in zora-op-geth.service file

Start op-node

Once you've started op-geth, you can start op-node. op-node will connect to op-geth and begin synchronizing the Zora network. op-node will begin sending block payloads to op-geth when it derives enough blocks from Ethereum

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

sudo systemctl enable zora-op-node.service #enable zora-op-node service at system startup

sudo systemctl start zora-op-node.service #start zora-op-node

sudo nano /etc/systemd/system/zora-op-node.service #make changes in zora-op-node.service file

Monitor the logs for errors

sudo journalctl -fu zora-op-node.service #follow logs of zora-op-node.service

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

You are expected to get following log messages from op-node

Run `curl` command in the terminal to check the status of your node

curl -H "Content-type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://localhost:8545

If it returns false then your node is fully synchronized with the network

Sync speed depends on your L1 node, as the majority of the chain is derived from data submitted to the L1.

You can check your syncing status using the `optimism_syncStatus` RPC on the `op-node`

command -v jq  &> /dev/null || { echo "jq is not installed" 1>&2 ; }
echo Latest synced block behind by: \
$((($( date +%s )-\
$( curl -s -d '{"id":0,"jsonrpc":"2.0","method":"optimism_syncStatus"}' -H "Content-Type: application/json" http://localhost:7545 |
   jq -r .result.unsafe_l2.timestamp))/60)) minutes
