Non-fungible tokens, or NFTs, are collectible elements within the Ethereum blockchain that usually follow the ERC-721 or ERC-1155 standard. They represent something unique and therefore are not mutually interchangeable. In other words, no non-fungible token is the same. NFTs take advantage of innovative smart contract technology to store and record unique information on the blockchain, which means that whenever an NFT is created, only one of it verifiably exists. NFT creators can also encrypt details such as rich metadata or secure file links allowing people to create all sorts of digital assets which are verifiable such as videos and songs. With NFTs, one can digitally certify that an asset is authentic.
