Code Explanation:

The core of this program revolves around creating and managing a simple Blockchain system, which is a vital technology behind publicly verifiable databases with efficient updating operations. Each record or block in the chain contains transactions, a timestamp, a link to the previous record (previous hash), and its unique hash computed through a proof-of-work mechanism.

Block Class: Represents a single record in the Blockchain. It contains methods for computing its hash and proving that computation effort was spent in generating a hash that meets the network’s difficulty criteria (‘proof of work’). The nonce value is used here to adjust until the hash satisfies the difficulty level.

Blockchain Class: Manages a chain of blocks. It automatically generates a ‘genesis’ block when initialized. The ‘add_block’ function allows new records to be added, ensuring the continuity by linking it to the previous block’s hash. The ‘is_valid_chain’ function ensures the integrity of the blockchain by confirming that each block indeed links back correctly to its predecessor and the hashes are valid.

The Blockchain system ensures data integrity and public verifiability by making it computationally infeasible to alter any data without redoing the proof of work for the altered block and all subsequent blocks. Hence, it plays a significant role in updating and maintaining transparent and tamper-proof databases.
