In below article from Forbes, an NFT is a digital asset that represents real-world objects like art, music, in-game items and videos. They are bought and sold online, frequently with cryptocurrency, and they are generally encoded with the same underlying software as many cryptos.
NFT allows the buyer to own the original item. Not only that, it contains built-in authentication, which serves as proof of ownership. Collectors value those “digital bragging rights” almost more than the item itself.
