A non-fungible token (NFT) is a special type of cryptographic token which represents something unique; non-fungible tokens are thus not mutually interchangeable. This is in contrast to cryptocurrencies like bitcoin, and many network or utility tokens that are fungible in nature.

Applications

Art was an early use case for blockchain. NFTs prove authenticity and ownership of digital art. The launch of CryptoPunks In June 2017 paved the way for "rare" art on the Ethereum Blockchain. DADA.art built from the CryptoPunks model and launched the first marketplace for rare digital art in Oct 2017. In 2018, one of FRORIEP Legal firm’s partners, Catrina Luchsinger Gaehwiler and the ING Bank Art Collection in Amsterdam, purchased what was claimed to be the first art-based asset NFTs in a blockchain governed Patron Protocol (created by artplus.io in 2016) of 8 fractional ownership shares. The work is called “The Absence of Presence” by Romanian artist Dragos Alexandrescu, who lives and works in Vaasa, Finland.

Specific token standards have been created to support the use of a blockchain in gaming. These include the ERC-721 standard of CryptoKitties, and the more recent ERC-1155 standard.

ERC-721 Standard

ERC721 was the first standard for representing non-fungible digital assets. ERC721 is an inheritable Solidity smart contract standard, meaning that developers can easily create new ERC721-compliant contracts by importing it from the OpenZeppelin library.

ERC-1155 Standard

ERC1155, brings the idea of semi-fungibility to the NFT world as well as it provides a superset of ERC721 functionality, meaning that an ERC721 asset could be built using ERC1155.

Growth and mainstream appeal

Non-fungible tokens first became popular when CryptoKitties went viral and subsequently raised a $12.5 million investment. RareBits, a Non-Fungible Token marketplace and exchange, raised a $6 million investment. Gamedex, a collectible cards game platform made possible by NFTs, raised a $800,000 seed round. Decentraland, a blockchain-based virtual world, raised $26 million in an initial coin offering, and had a $20 million internal economy as of September 2018. Nike holds a patent for its blockchain-based NFT-sneakers called ‘CryptoKicks’..

On February 19, 2021, the Nyan Cat sold for 300 ETH ($591,702.00 on that day) as an NFT.
