Lesson Overview

4.2 – How Blocks Are Linked Together: Blocks are connected through cryptographic hashes, forming an unbreakable digital chain. Each block includes a unique identifier that references the one before it, creating chronological order and security. This linking ensures that changing even one detail in a past block would break the entire chain. This interlocking system is what gives blockchain its name and trustworthiness. It eliminates the need for central oversight by making manipulation detectable instantly. Understanding how these links work clarifies why blockchain is considered tamper-proof and transparent. Every successful network, from Bitcoin to Ethereum, depends on this structural connection to maintain data integrity.
