Bitcoin Mining Simulation

Overview

This project is a simple Python simulation of Bitcoin mining. It demonstrates the core concepts of blockchain mining, such as generating transactions, calculating hashes, and solving proof-of-work problems by finding a valid nonce.

Features

Random transaction generation.
SHA-256 hashing of block data.
Proof-of-work implementation with adjustable difficulty.
Simulation of blockchain block creation.

Requirements

Python 3.6+

Installation

Clone the repository or download the source code:
```
git clone <repository-url>
```

Usage

Run the script:
```
python main.py
```
The program will generate random transactions, mine blocks, and display the resulting hashes.

Example Output

Mining Block 1 with Transactions: 12345->67890->50; 54321->09876->30; 11111->22222->20
Block found! Nonce: 45678, Hash: 00000f9d6c24...
New Hash: 00000f9d6c24...

Configuration

The script contains configurable constants to adjust the mining simulation:

MAX_NONCE: Limits the number of nonce iterations for mining. Default is 1,000,000.
DIFFICULTY: Specifies the number of leading zeros required in the hash. Default is 6.

To modify these values, edit the script directly:

MAX_NONCE = 1000000  # Set a higher or lower limit as needed
DIFFICULTY = 6       # Adjust difficulty for faster or slower mining

Project Structure

mining_simulation.py: Main script containing all functionality for the simulation.

How It Works

Transaction Generation: Random transactions are created with a sender, receiver, and amount of bitcoins.
Hash Calculation: Each block is hashed using SHA-256.
Proof-of-Work: The script iterates through possible nonce values to find a hash matching the difficulty.
Blockchain Simulation: Each block references the previous block's hash, forming a simple blockchain.

Limitations

This is a simplified simulation and does not represent the full complexity of real-world Bitcoin mining.
The script is single-threaded and not optimized for performance.
