WHAT IS BLOCKCHAIN?
Imagine I send you an image via WhatsApp; as soon as you receive it, you can send it to all your friends, and they can send it to all their contacts. This means that the image can exist in multiple places at the same time. We couldn't move money this way because it would be counterfeiting; we would all have the same currency.
Now imagine that I send the image through the blockchain; as soon as you receive it, it disappears from my phone, and when you send it to your friend, it will disappear from yours, meaning that this file can only exist in one single place at a time.
Now we can move money because we are sure we are receiving the original file; this allows us to move
"value" securely.
