SPV Nodes Interactive GUI

Overview

The SPV Nodes Interactive GUI is a graphical user interface (GUI) for interacting with Simplified Payment Verification (SPV) nodes in a blockchain network. It enables users to query blockchain data efficiently without running a full node, making it lightweight and resource-efficient.

Features

• User-friendly GUI for blockchain interactions
• Efficient SPV-based queries without requiring a full blockchain node
• Blockchain data visualization
• Interactive and responsive design
• Backend API for blockchain data management

Prerequisites

Ensure that you have the following installed on your system:

• Python 3.8 or later
• pip (Python package manager)
• Graphviz (for visualization)

Installation

1. Clone the repository

   git clone https://github.com/your-repository/SPV-Nodes-Interactive-GUI.git
   cd SPV-Nodes-Interactive-GUI

2. Install dependencies

   pip install -r requirements.txt

3. Ensure Graphviz is installed

   • Download and install from Graphviz Official Site.
   • Verify installation:

     dot -V

Running the Application

To launch the GUI, execute the following command:

python frontend.py

To start the backend server:

python Backend/backend_api.py

Troubleshooting

If you encounter issues, try the following:

• Ensure Python and dependencies are installed properly.
• Check that Graphviz is installed and accessible in your system's PATH.
• Run the script in a virtual environment:

  python -m venv venv
