What is Blockchain?
When people hear "blockchain," they often think of cryptocurrency, scams, or risky trading — and that can make them feel unsure or worried.
But that's not what blockchain is. Blockchain is a secure technology, not a coin or a trading app. It's a way to protect your data, your money, or any important information using powerful encryption and a system that no one can secretly change.
It's like a digital lockbox
Every record inside is verified by hundreds or thousands of computers around the world, not controlled by any one person or company. That's why it's being used in hospitals, banks, logistics, even government voting systems.
For example: Let's say you send money to your friend. Usually, the bank keeps a record of it. But only the bank can see or change that record.
