Step 1: Ensure System Requirements

• CPU: 4+ cores (8+ cores recommended for production)
• RAM: 8+ GB (16 GB or more recommended)
• Disk: 500 GB SSD (preferably NVMe)
• Operating System: Ubuntu 20.04 LTS or 22.04 LTS
• Network: Stable internet connection with at least 1 Gbps bandwidth

Step 2: Install Dependencies

Start by installing basic dependencies for building blockchain nodes. Update your system and install essential packages:

sudo apt update && sudo apt upgrade -y
sudo apt install curl wget git build-essential libssl-dev pkg-config libclang-dev cmake -y

Step 3: Install Go

As Nexus is expected to be a blockchain platform, and many similar projects use Go for node development, you will need to install the Go programming language. To do so:

wget <https://go.dev/dl/go1.21.1.linux-amd64.tar.gz>
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.21.1.linux-amd64.tar.gz
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.bashrc
source ~/.bashrc
go version

Step 4: Clone the Nexus Repository

Once the official Nexus testnet repository is released, you will need to clone it. For now, this step assumes you’ll find the repository at a URL like:

git clone <https://github.com/nexusprotocol/nexus.git>
cd nexus
