A unique digital certificate or token that authenticates the ownership of a virtual or physical asset such as a collectible, image or film. It is stored on the blockchain, a public digital ledger that records such transactions. An artwork sold in this manner is tokenised and, when purchased, records and transfers ownership to the buyer. In some instances, it may also include terms and conditions of usage, allowing, for example, an artist to receive a share of the transaction value of a future sale of the work. Unlike currency, which is a fungible asset and therefore interchangeable, a non-fungible token is unique and cannot be interchanged. However, while the token verifies ownership, it may not protect the image from being copied and used by non-owners.
