A non-fungible token (NFT) is a special type of cryptographic token which represents something unique; non-fungible tokens are thus not interchangeable. This is in contrast to cryptocurrencies like bitcoin, and many network or utility tokens that are fungible in nature.[1]

Applications[edit]

Non-fungible tokens are used to create verifiable digital scarcity, as well as player ownership, and the possibility of asset interoperabilty across multiple games[2]. NFTs are used in several specific applications that require unique digital items like crypto-collectibles and crypto-gaming.

Popular blockchain games like CryptoKitties make use of non-fungible tokens on the Ethereum blockchain.[3] NFTs are used to represent in-game assets, and are controlled by the user, instead of the game developer.[4] This lets the assets be traded on third-party marketplaces without permission from the game developer. NFTs also find potential use in digital art, by helping prove authenticity and ownership.[5]

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

Growth and mainstream appeal[edit]

Non-fungible tokens made their way into mainstream news when CryptoKitties went viral [6][7] and subsequently raised a $12.5 million investment.[8] RareBits, a Non-Fungible Token marketplace and exchange, raised a $6 million investment.[9] Gamedex, a collectible cards game platform made possible by NFTs, raised a $800,000 seed round.[10] Decentraland, a blockchain-based virtual world, raised $26 million in an initial coin offering,[11] and had a $20 million internal economy as of September 2018.[12]
