What is Blockchain? Most people still don’t fully get it — so let me break it down.
Imagine a chain made of boxes, not metal ones, but digital boxes that store information. Each box has two special seals made of digital glue called hashes.
Here’s how it works:
The first seal (or hash) on one side of the box is like a fingerprint — it's based on the contents of the previous box. That means every box is linked to the one before it, forming a secure, unbreakable chain.
Inside the box, there’s a page where you can write data. Not just financial transactions — you could store anything: contracts, records, even voting info.
Once the data is written, the other side of the box gets sealed with a new, unique hash — one that’s based on the current box’s content. This seal becomes the first seal of the next box.
This clever design makes it nearly impossible to tamper with anything. If you try to change one box, the fingerprints won’t match anymore, and the whole chain breaks.
That’s the magic of blockchain — a secure, transparent, and unchangeable digital ledger, built box by box.
