Everyone understands that the original Mona Lisa is in the Louvre, and all postcards with her image are reproductions. But what is original in the digital world where anyone can right-click on an image and save a perfect copy to their phone? How do you confirm the ownership of a particular file, or how do you keep the ownership history?
The advent of NFT solves these issues.
NFT is a way to turn any file (such as an image or video) into a record on the blockchain, which means that this file now has a unique identifier and can serve as an asset that can be transferred, sold, and cannot be tampered with or simply copied.
All this is possible thanks to the properties of the blockchain where information is stored unchanged and transparent.
