What is a Blockchain?
Think of blockchain as a digital ledger book that everyone can see, but no one can cheat.
🇬🇭 Ghana Example:
Imagine you and your friends keep track of who owes money in a shared notebook. Everyone has a copy, so no one can lie about what they owe. That's blockchain!
Key Characteristics:
-
✓
Transparent: Everyone can see all transactions
-
✓
Immutable: Once written, it can't be changed
-
✓
Decentralized: No single person or bank controls it
Blockchain = Block (group of transactions) + Chain (linked together)
