NFT - wtf?
Non-fungible tokens ("NFT") are used to create verifiable artificial scarcity in the digital domain, as well as digital ownership. 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 technology in general, because of the ability of NFTs to provide proof of authenticity and ownership of digital art.
NFTs can also be used to represent in-game assets which are 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.
