Blast

Blast is a fork of Optimism’s open-source OP Stack. In this guide, Blast forked Optimism's op-geth and op-nodebinaries are built from source to facilitate the node's installation.

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.

Pre-Requisites

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

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

Allow P2P Connections

sudo ufw allow 30304/tcp
sudo ufw allow 30304/udp

Enable Firewall

sudo ufw enable

To check the status of UFW and see the current rules

sudo ufw status verbose

Compile Blast-geth

git clone https://github.com/blast-io/blast.git

cd blast/blast-geth

git checkout tags/v1.1.0 -b v1.1.0

make

#The binary is built at /root/blast/blast-geth/build/bin/geth

Create JWT secret file and download genesis and rollup .json files

cd /root/data/blast/geth/blast-geth

openssl rand -hex 32 | tr -d "\n" > /root/data/blast/geth/blast-geth/jwt.hex

cd /root/blast

git clone https://github.com/blast-io/deployment.git #contains genesis and rollup configs

Bootstrap the node by running

/root/blast/blast-geth/build/bin/geth --datadir /root/data/blast/geth/blast-geth/ init /root/blast/deployment/mainnet/genesis.json

Start blast-geth

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

sudo systemctl start blast-geth.service #start blast-geth

sudo systemctl enable blast-geth.service #enable blast-geth service at system startup

sudo journalctl -fu blast-geth.service #follow logs of blast-geth service

To check or modify blast-geth.service parameters simply run

sudo nano /etc/systemd/system/blast-geth.service

Ctrl+X and Y to save changes

You can run curl command in the terminal to check the status of your node

curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false]}' \
  -H "Content-Type: application/json" http://localhost:8545

Compile Op-node (Blast-optimism)

cd blast/blast-optimism

make op-node

Create systemd service

Make sure to replace --l1 and --l1.beacon flags with your own synced Ethereum L1 RPC URL (e.g. Erigon) and L1 Consensus Layer Beacon endpoint (e.g. Lighthouse)
