# NFT Tokens

A **non-fungible token is a unit of data stored on a blockchain**, that certifies a digital asset to be unique and therefore not interchangeable. It means that NFTs are unique. They **cannot be duplicated or replaced** - only one token can exist. Ethereum allows users to easily store, create and send NFT tokens, therefore the **Ethereum network** is the market leader.

NFTs can be used to represent items such as photos, videos, audio, and other types of digital files. NFTs are frequently used to sell a wide range of virtual collectibles, including NBA virtual trading cards, music, digital images, video clips, and even virtual real estate in a virtual world.\
