Unique unit of cryptographic currency For other uses, see NFT (disambiguation).

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

Non-fungible tokens are used to create verifiable digital scarcity, as well as digital ownership, and the possibility of asset interoperability across multiple platforms. NFTs are used in several specific applications that require unique digital items like crypto art, digital collectibles, and online gaming. Art was an early use case for NFTs, and blockchain in general, because of its ability to provide proof of authenticity and ownership of digital art that has otherwise had to contend with the potential for mass reproduction and unauthorized distribution of art through the internet.

NFTs can also be used to represent in-game assets which were controlled by the user instead of the game developer. NFTs allow assets to be traded on third-party marketplaces without permission from the game developer.

Growth and mainstream appeal

In June of 2017 CryptoPunks were released as the first non-fungible token (NFT) on the Ethereum blockchain by American studio Larva Labs, a two-person team consisting of Matt Hall and John Watkinson. In late 2017 another project called CryptoKitties was released and 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’. The album When You See Yourself by Kings of Leon will be the first musical album distributed as non-fungible tokens. In February 2021, the musician Grimes sold around $6 million worth of digital art on Nifty Gateway.

Later, in February 2021, US-American digital artist Beeple's work "Everydays. The first 5000 days" was the first NFT artwork to be listed in major auctions house Christie's. A few days before, the meme animation Nyan Cat had been sold on an internet market place for 600,000 USD.

Dapper Labs and NBA Top Shot

Dapper Labs, in partnership with the NBA, launched a beta version of their NBA TopShot collectable and tradable NFT based app in the first half of 2020, which they had been working on since 2018. It sells tokens in packs which they say contain multimedia and data smashed together. On October 1, 2020 it was announced that they had exited the beta and opened to all fans. As of February 28, 2021, Dapper Labs was reporting over $230 million in gross sales in the app.

Ethereum Token Standards

Specific token standards have been created to support the use of a blockchain in gaming. These include the Ethereum 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.
