NFT stands for "non-fungible token". It sounds mysterious, but the idea is simple: it is a digital certificate stored on a blockchain that confirms a given item is unique and belongs to a specific wallet. The word "non-fungible" is key here. You can exchange one euro for another euro with no difference at all, but you cannot swap one NFT for another one to one, because each has its own unique number and history. It is precisely this uniqueness that sets it apart from an ordinary cryptocurrency.
What it is really for
Pictures and collectible avatars are only one use case, and not the most important one. NFTs are useful wherever it matters to confirm that something is an original or that someone has a right to something.
Examples beyond art:
- tickets to concerts and events, which are harder to counterfeit and easier to settle on resale,
- in-game items that a player truly owns and can carry beyond a single game,
- diplomas and certificates whose authenticity can be verified quickly,
- music tracks and other content from which the creator can automatically receive a share of every resale,
- proof of product provenance, for example for luxury goods, as protection against counterfeits.
In each of these cases the NFT works like a seal: it is not so much "pretty" as "confirming a fact". It is also worth knowing that the image or audio file itself is usually not stored on the blockchain. The token contains a reference to it and a record of who the owner is. This distinction is often a source of misunderstandings.
Common misconceptions
Quite a few myths have grown around NFTs. It is worth clearing up a few of them:
- an NFT is not a cryptocurrency: cryptocurrencies are mutually interchangeable, while each NFT is separate and unique,
- owning an NFT is not the same as owning the copyright: when you buy a token, you usually acquire only the ownership record, not the right to copy or commercially use the work,
- a screenshot does not steal anything: a copy of the file exists, but it is the entry on the blockchain that says who owns the original,
- an NFT does not have to harm the environment: many networks have switched to the energy-efficient proof of stake mechanism.
An NFT is not a picture, it is a proof of ownership, and that is something entirely different.
The simplest way to think about an NFT is as a digital deed of ownership or a certificate of authenticity. The token itself does not guarantee that something is valuable. Its worth depends on what the token represents and how it is used. Before you buy an NFT, check carefully what you are getting and what rights come with it.
