What is NFT? Non-Fungible Token (NFT) is a kind of blockchains.
What distinguishes NFTs from fungible , and ownership of the NFT is often associated with a license to use the underlying asset.
There are standards or convensions for NFTs on blockchain. For example, ERC-721 is a standard for representing non-fungible digital assets on the Ethereum blockchain, and SimpleAssets is an digital assets standard for NFTs, FTs and NTTs on EOSIO blockchains.
