Lesson Overview

1.6 – Anatomy of a Block: Data, Hash, and Timestamp: Every block in a blockchain contains three key parts: the data it records, a cryptographic hash that identifies it, and a timestamp showing when it was added. The hash acts like a digital fingerprint—unique and impossible to duplicate. If someone alters the block’s contents, the hash instantly changes, alerting the network. Linking hashes creates a secure timeline of events that cannot be rewritten. The timestamp confirms when each block joined the chain, ensuring chronological accuracy. This simple structure forms the backbone of blockchain’s reliability and resistance to fraud or tampering.
