Immutable: Once something’s on the blockchain, it’s stuck there forever.

You can’t just delete it or change it like you would with a regular database.

Transparent: Anyone can see the transactions. It’s like having a giant group chat where all the receipts are public—except only your wallet ID shows, not your name.

Secure: It’s way harder to hack a blockchain than a regular system because you’d need to change the data on every single computer running the blockchain at the same time. Not gonna happen.
