Lesson Overview

4.1 – What Is a Block: A block is the fundamental building unit of every blockchain network. It acts like a secure digital record containing bundles of verified transactions that are permanently stored. Each block carries a timestamp, transaction data, and a cryptographic reference to the block before it. This structure prevents tampering and ensures transparency across the system. Understanding blocks is essential because they form the base of decentralized trust. Once data is written to a block, it becomes immutable, creating an unchangeable historical ledger. Every cryptocurrency, smart contract, and digital asset movement relies on this simple yet powerful structure of data integrity.
