Simple Python Blockchain

A minimal blockchain implementation in Python to demonstrate key blockchain concepts such as:

• Block structure
• Hashing using SHA-256
• Proof of Work
• Chain validation

Getting Started

This project builds a basic blockchain from scratch using Python. You can simulate block addition and validate the chain.

How It Works

Each block includes:

• Index
• Timestamp
• Data
• Nonce
• Previous hash
• Current hash

Proof of Work requires the hash to start with a fixed number of zeroes.
