NFTs (can be referred to as “digital tokens” or “Nifties”) are digital objects that can be sold and through which some income can be earned. To give an even more precise definition it is also possible to refer to them as a kind of ownership certificates that attest that a particular owner or author of a work, has the rights to it.One very important feature of NFTs is that they do not possess a tangible form, but despite this, they can still be sold and bought. The point is that they are “unique,” because they cannot be categorized as “fungible” goods.This means that they are not interchangeable units with others of the same value. However, they can be bought and sold through special platforms. In other words, we are talking about something unique, “goods” that cannot be replaced with others of the same type.
