📘 What is Blockchain? A Beginner's Guide
When you hear "blockchain," you might think of Bitcoin—but blockchain is much more than just crypto. It's a revolutionary technology that allows information to be stored in a secure, decentralized, and tamper-proof way.
🔍 Think of It Like This:
Imagine a record book that only your bank owns. If it's lost, hacked, or altered, all the information could be compromised.
Now, imagine that same book—but everyone in the network has a copy, and if one person tries to cheat, the system rejects it instantly. That’s the power of blockchain.

🧱 How Does Blockchain Work?
1. Blocks
Each block stores a group of transactions. It includes:
Who sent what to whom
A timestamp
A unique code called a hash
2. The Chain
Each block is linked to the one before it using its hash, creating a secure chain.
🔗 If someone changes data in an old block, the hash changes—breaking the entire chain. That makes fraud easy to detect and prevent.
3. Decentralization
Instead of one central database, the blockchain is spread across thousands of computers (nodes) worldwide.
No single owner or point of control
Extremely secure and transparent
Nearly impossible to tamper with
