Rust_blockchain

This implementation includes:

1. Block struct: represents a single block in the blockchain.
2. Blockchain struct: manages the chain of blocks and pending transactions.
3. add_block method: creates a new block and adds it to the chain.
4. calculate_hash method: calculates the hash for a block.
5. add_transaction method: adds a transaction to the pending transactions.
6. mine_block method: creates a new block from pending transactions.

Run the code using cargo run to see the blockchain in action!

Keep in mind that this is a highly simplified example. Real-world blockchains require additional features like:

• Consensus algorithms (e.g., Proof of Work, Proof of Stake)
• Network communication
• Cryptographic signatures
• Transaction validation
• Security measures

Note: This is a basic example for educational purposes only. Real-world blockchains require additional features, security measures, and testing.
