“What is Blockchain?” Explained in Simple Terms
Imagine a notebook that everyone can see, but no one can erase.
That’s blockchain — a digital ledger shared across many computers.
Here’s how it works:
You make a transaction.
It gets added to a “block.”
That block joins a chain of other blocks.
Once added, it can’t be changed.
It’s transparent, secure, and decentralized — no middlemen needed!
This tech powers Bitcoin, Ethereum, and more.
