A Non-Fungible token is a digital asset, which can be transferred, traded and exchanged. Through the use of NFT technology, owners are given ownership and control of their assets. An NFT is not like a valuable item for example – no one will ever be able to duplicate your cat coin or collectables token. There is no centralised record of the blockchain, so all data must be stored on individual user devices and applications rather than being held in one place.
