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, meaning that image can exist in several 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 I send you the image through 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 file can only exist in one place at the same time.

Now we can move money because we are sure that we are receiving the original file, allowing us to move

"value" securely.
