Quantum Blockchain – Windows Node Client

This folder contains a PowerShell client that connects a Windows PC to your Quantum Blockchain node (running on your phone, server, or another machine).

Files

• quantum_blockchain_node.ps1 – the Windows client node.
• README.html – this document.

1. Configure the Node Address

Open quantum_blockchain_node.ps1 in a text editor and find this section near the top:

$NodeBaseUrl = "http://192.168.1.23:5000"

Change this URL to the IP address and port where your blockchain node is running. Examples:

• Phone on Wi-Fi (Termux node): http://192.168.0.42:5000
• Node running on the same PC: http://127.0.0.1:5000

Your Termux / phone blockchain server must expose HTTP endpoints that match the paths configured in the script (e.g. /api/account, /api/mine, /api/data, /api/chain).

2. Run the Client on Windows

1. Right-click the Start menu and open Windows PowerShell (or PowerShell).
2. Change directory to this folder. Example:

   cd C:\Users\YourName\Desktop\QuantumNode

3. Allow scripts in this session:

   Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

4. Run the client:

   .\quantum_blockchain_node.ps1

3. Menu Options

• 1. Create Account – calls POST /api/account on your node and saves the wallet locally.
• 2. Mine Quantum Coins – calls POST /api/mine using your wallet’s public key.
• 3. Post Data to Blockchain – calls POST /api/data with your data payload.
• 4. Retrieve Data from Blockchain – calls GET /api/chain and prints the chain.

4. Important

• This client is real – if your node is offline, it will fail instead of faking success.
• The “quantum” logic (e.g., IBM Q, Qiskit, etc.) should live on the node side – this client just talks to it.
• You can adapt the endpoint paths and JSON fields in the script to match your existing Termux implementation.
