The Non-Fungible Token (NFT) technology works differently. Each non-fungible token is unique and cannot be counterfeited, split, or subtly replaced. All information about its author, buyer, and all transactions with it is securely stored in the blockchain.
In other words, NFT is a digital certificate attached to a unique object. Moreover, the object itself can be both digital and real. NFT = Blockchain Entry + Metadata + Media.
