Blockchain Implementation Using Python

This project is a Python implementation of a simple blockchain with core functionalities like Proof of Work (POW), mining, and block validation.

Features

• Block Creation: Generates blocks with index, timestamp, data, proof, and previous hash.
• Mining: Implements Proof of Work by finding a valid hash starting with four leading zeros.
• Blockchain Validation: Verifies the integrity of the blockchain.
• Tamper Detection: Detects modifications to the blockchain.

Requirements

• Python 3.x
• FastAPI
• Uvicorn

How to Run

1.Clone the repository:

  git clone https://github.com/MONGSING/BlockChain

2.Install dependencies:

  pip install fastapi uvicorn

3.Run the blockchain:

  python Main.py

Blockchain Structure

Each block contains the following:

• Index: Position in the chain.
• Timestamp: Time of block creation.
• Data: Information stored in the block.
• Proof: Proof of Work for the block.
• Previous Hash: Hash of the previous block.
