# 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
|
|
|
|
1. Clone the repository or download the source code:
|
|
```bash
|
|
git clone <repository-url>
|
|
```
|
|
|
|
## Usage
|
|
|
|
1. Run the script:
|
|
```bash
|
|
python main.py
|
|
```
|
|
2. 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:
|
|
|
|
```python
|
|
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
|
|
|
|
1. **Transaction Generation**: Random transactions are created with a sender, receiver, and amount of bitcoins.
|
|
2. **Hash Calculation**: Each block is hashed using SHA-256.
|
|
3. **Proof-of-Work**: The script iterates through possible nonce values to find a hash matching the difficulty.
|
|
4. **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.
