Ever wondered why blockchain is called unhackable?
🧱 Imagine a notebook on a table.
Every time a transaction happens, a new page is added.
📄 Each page = a block
🔗 Pages linked together = a chain
Now imagine:
Everyone has a copy of this notebook
Anyone can check it
No one can secretly erase or change a page
That shared notebook is called blockchain.
Once something is written, it stays there.
That’s why blockchain creates trust without banks or middlemen.
Simple idea. Powerful impact.
Now that you understand blockchain, what should we explore next?
