Code Explanation:

Here, we’ve simulated a rudimentary blockchain model tailored for smart grid cybersecurity. It involves the following components and logic:

• Block Class: Represents a block in the blockchain containing transactions (smart grid exchanges), a timestamp, the hash of the previous block (linking it to the chain), and a nonce used in the proof-of-work algorithm.
• Blockchain Class: Manages the chain of blocks, including adding new transactions and mining new blocks. The mining process involves finding a proof (nonce) that results in a valid hash (beginning with a certain number of zeros), demonstrating work done to secure the block.
• Proof of Work: A consensus algorithm that validates new blocks (with transactions) by requiring computational work, thus securing the chain against tampering or invalid transactions.
• Genesis Block: The first block in the chain, created manually to initiate the blockchain.
• Mining and Transaction Addition: New transactions are added to a pool of unconfirmed transactions. The mine function creates a new block with these transactions, finds the proof of work, and adds the block to the chain.

This simplified model succinctly presents the notion of using blockchain technology to ensure the integrity and security of data transactions within a smart grid, showcasing blockchain’s potential in cybersecurity applications.
