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

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 Blast 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

To check the status of UFW and see the current rules

sudo ufw status verbose

Build the Execution Engine (l2geth)

Clone the Boba Legacy Monorepo and build l2geth:

mkdir bobabnb && cd bobabnb

git clone https://github.com/bobanetwork/boba_legacy.git

cd boba_legacy

cd l2geth

make geth

Create database directories for l2geth and DTL:

mkdir -p /root/data/bobabnb/geth/dtl

mkdir -p /root/data/bobabnb/geth/l2geth

Creating password and block-signer key

cd /root/data/bobabnb/geth/l2geth/

touch password

echo "6587ae678cf4fc9a33000cdbf9f35226b71dcc6a4684a31203241f9bcfd55d27" > /root/data/bobabnb/geth/l2geth/block-signer-key

/root/bobabnb/boba_legacy/l2geth/build/bin/geth account import --datadir=/root/data/bobabnb/geth/l2geth/ --password /root/data/bobabnb/geth/l2geth/password /root/data/bobabnb/geth/l2geth/block-signer-key

Import genesis information and initialize l2geth

cd /root/bobabnb/boba_legacy/packages/data-transport-layer

wget https://raw.githubusercontent.com/bobanetwork/boba_legacy/develop/boba_community/boba-node/state-dumps/bobabnb/state-dump.latest.json -O /root/bobabnb/boba_legacy/packages/data-transport-layer/state-dump.latest.json

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:

INFO [08-01|04:29:56.601] Syncing transaction range                start=39649105 end=39649105 backend=l2
