The BobaBNB archive node has a size of 525GB on August 8th, 2024
BobaBNB
Boba Network is built on the Optimistic Rollup developed by Optimism, which ensures EVM and Solidity compatibility, minimizing the efforts required to migrate smart contracts from L1 to L2.
In this guide, we are walking through the process of setting up a BobaBNB archive node using l2geth and DTL (Data Transport Layer).
BobaBNB is a Layer 2 scaling solution for the Binance Smart Chain (BSC), designed to enhance transaction throughput and reduce fees while maintaining the security of BSC. By deploying a BobaBNB archive node, you gain access to the complete transaction history, enabling advanced queries and analytics
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
To check the status of UFW and see the current rules

Launch BobaBNB
Start DTL
sudo systemctl daemon-reload #refresh systemd configuration when changes made
sudo systemctl enable dtl.service #enable dtl service at system startup
sudo systemctl start dtl.service #start dtl
sudo nano /etc/systemd/system/dtl.service #make changes in dtl.service file
Start l2geth
sudo systemctl daemon-reload #refresh systemd configuration when changes made
sudo systemctl enable l2geth.service #enable l2geth service at system startup
sudo systemctl start l2geth.service #start l2geth
sudo nano /etc/systemd/system/l2geth.service #make changes in l2geth.service file
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
When it returns false then your node is fully synchronized with the network
Monitor the logs for errors
sudo journalctl -fu dtl.service #follow logs of dtl.service
sudo journalctl -fu l2geth.service #follow logs of l2geth.service
During the synchonization, you are expected to get following log messages from DTL:
{"level":30,"time":1722479386601,"method":"GET","url":"/transaction/latest?backend=l2","elapsed":0,"msg":"Served HTTP Request"}
{"level":30,"time":1722479393551,"fromBlock":39649105,"toBlock":39649106,"msg":"Synchronizing unconfirmed transactions from Layer 2 (Optimism)"}
and l2geth:
