NFT (non-fungible token) is a unique blockchain code element - similar to a cryptocurrency. The difference between them is the non-exchangeability of the NFT token - it is unique and cannot be exchanged for another, and in most cases - it cannot be divided. It is created by saving the file on a special platform that creates a unique NFT token and saves it in a global directory.
Why does the file saved in this form have some value? First of all, it is impossible to create another copy of it or forge it. It is the only one in the world and unique - just like a work of art. Of course, you can copy the file with it, but the code assigned to it remains unchanged.
The first solutions to use NFT were online games - the first was CryptoKitties, where players breed and trade digital cats that possess unique characteristics "inherited" from their digital parents. Cats cost specific, cryptocurrency money. Already in 2017, in which the game was created, transactions of $ 12 million were made through CryptoKitties.
