The Boba Mainnet archive node has a size of 12GB on July 29, 2024
Boba
Boba is built on the Optimistic Rollup developed by Optimism.
In this guide, we are walking through the process of setting up a Boba Mainnet archive node using a forked version of Optimism's op-erigon,op-node and l2geth. These three components must be configured together to ensure that the node can effectively serve all historical data, which may be necessary when an Indexer syncs a specific subgraph on the Boba Network
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.
Release branches are created when new versions of the op-node are created. Read through the Releases page to determine the correct branch to check out.
Create database directory for l2geth, download and extract archive snapshot:
mkdir-p/root/data/boba/boba-legacy/&&cd/root/data/boba/boba-legacy/aria2c --file-allocation=none -c -x 10 -s 10 "https://boba-db.s3.us-east-2.amazonaws.com/mainnet/boba-mainnet-geth-db-legacy.tgz"

Create systemd service for l2geth
sudonano/etc/systemd/system/boba-legacy.service
Paste the configs and save by entering ctrl+X and Y+ENTER:

Create database directory, download and extract the most recent snapshot
Consider verifying a snapshot by comparing the sha256sum of the downloaded file to the sha256sum listed on this page. Check the sha256sum of the downloaded file by running sha256sum <filename>in a terminal
It's usually simpler to begin with startingop-erigon before you start op-node. You can start op-erigon even if op-node isn't running yet, but op-erigon won't get any blocks until op-node starts.

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

During the initial synchonization, you are expected to get following log messages from op-node
INFO [08-04|16:36:07.150]Advancingbqoriginorigin=df76ff..48987e:8301316originBehind=false
After a few minutes, op-node finds the right batch and then it starts synchronizing. During this synchonization process, you get log messags 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:9545
If it returns false then your node is fully synchronized with the network
