🔗 The Linking Mechanism

Let's break down exactly how blocks link together using cryptographic hashes. It's simpler than you think!

Block 1 is Created

First block contains data and gets hashed

Block #1

Data: Genesis Block Data

This is the first block in the chain

See how Block 2's hash changes when you modify its data:

Block #2 Data

Block #1 Hash (unchanged)

00002c9156cb

Block #2 Hash (changes)

0000684eb4b4

1️⃣

Previous Hash Field: This is the critical link. Every block (except the first) contains the previous block's hash.

2️⃣

Cascading Effect: Change Block 1's data → Block 1's hash changes → Block 2's previous hash no longer matches → Chain breaks.

3️⃣

Genesis Block: The first block has no previous hash (it's the beginning of the chain).
