A simple blockchain implementation in Rust, demonstrating the basic principles of blockchain technology including creating blocks, implementing a Proof of Work system, and ensuring chain integrity.

• Block Creation: Create individual blocks containing data, timestamp, nonce, and hashes.
• Proof of Work: Implement a basic Proof of Work (PoW) system to secure block creation.
• Blockchain Integrity: Validate the integrity of the blockchain with hash-based linkages between blocks.

• Rust programming environment
• Cargo, Rust's package manager

After running the project, it will create a simple blockchain, add a few blocks, and display them along with their validity status.
