# What is an NFT?

The acronym NFT stands for ***Non-Fungible Token***.

***"Non-Fungible"*** means that it is a **unique** item and cannot be exchanged for another of the same kind. For example, a work of art cannot be exchanged for another because they both have characteristics that make them unique.

On the other hand, we have money or cryptocurrencies, which are **fungible.** This means that a dollar can be exchanged for another dollar, just as a bitcoin can be exchanged for another bitcoin, as they are identical and have the same value.

NFTs are considered **digital art** because, in addition to being unique, they are stored on the ***blockchain***, making it very easy to track who their owner is at any given moment.

But NFTs are much more than art; they can have **utility.** In the following sections, we will explain all the advantages that World Challenge NFTs offer you and everything you will be able to do with them.
