An NFT is a unique digital identifier that cannot be copied, substituted, or subdivided, that is recorded in a blockchain, and that is used to certify authenticity and ownership of a specific digital asset and specific rights relating to it. This digital asset is usually an image, audio, or video file. The NFT is not the asset itself, rather, it is a one-of-a-kind digital marker assigned to the asset as code stored within the blockchain. NFTs are themselves considered to be digital assets.
