How Does Blockchain Work?

At the heart of cryptocurrency is a technology called blockchain.

Simple Explanation:

• A blockchain is a digital ledger (record book)
• It stores all transactions across a network
• Each transaction is grouped into a “block”
• Blocks are connected in a chain → blockchain

Key Features:

• Transparent: Anyone can view transactions
• Secure: Data cannot be easily changed
• Decentralized: No single authority controls it

Imagine it like a Google Sheet shared with thousands of computers worldwide—no one can cheat or secretly edit it.
