🔎 What is Blockchain — in simple English

A blockchain is like a public notebook that anyone can read, but no one can secretly change.

🧱 Each “block” holds a list of transactions.

🔗 These blocks are connected in a chain — forming a secure history.

📖 Once information is added, it can’t be erased.

That’s why people call it trustless — not because it’s untrustworthy, but because you don’t need to trust anyone.

The system protects itself.

📌 Think of it as a permanent, digital receipt book.

What was your first impression of the word “blockchain”? 🤔
