🔗 What is a blockchain? (explained simply)
Imagine a digital ledger where each page is a block.
📖 Every time something happens (a transaction, a contract), it is written on a new page.
🛡️ No one can tear out the pages. No one can modify them secretly.
Everyone can read them. No one can falsify them.
This is the heart of the blockchain:
✅ Transparency
✅ Security
✅ Decentralization
It is not just "a technology", it is a revolution in the way to trust.
