What are central bank digital currencies and how would they work?

A central bank digital currency is like a super special toy that grown-ups can use to send and receive money instantly, just like how you trade your toys with friends at recess.

Imagine the central bank is like the principal of the school who has a big piggy bank full of coins. Right now, when people want to pay for things, they usually use paper money or plastic cards, but these are like old toy cars that can only go slow. A digital currency from the central bank would be like getting a brand new remote-controlled car, it’s faster and smarter.

Think of it like this: if you have a special app on your phone, you can use it to send money to your friend just by tapping a button. The principal (the central bank) makes sure that the money is real and that no one is cheating, kind of like how she checks if you're using the right number of toys when you trade.

Everyone in the school could have their own special toy car, so they can zoom around and pay for ice cream or a new pencil without needing to carry coins or wait for the cash machine. That’s what a central bank digital currency is, it's like giving everyone a super cool way to send money, fast and easy!
