How Blockchain Works: A Simple Explanation for Beginners

A blockchain is a digital ledger shared across a network. Instead of being stored on one server, copies of this ledger exist on thousands of computers around the world.

Think of blockchain as a Google Doc that anyone can view, everyone can verify, but nobody can secretly edit.

Every transaction is stored inside a 'block'. Once a block is full, it gets linked to the previous block, creating a chain. This chain forms a highly secure and transparent history of everything that has happened on the network.

• Blocks store batches of verified transactions
• Each block links cryptographically to the previous one
• Tampering with one block breaks the entire chain

Blockchain is the foundation of Bitcoin, Ethereum, NFTs, smart contracts, and most of modern Web3. Understanding it gives you a huge advantage as a new participant in crypto.
