Abstract: An online marketplace may authenticate an item, for example by identifying that the item has a unique characteristic. The online marketplace may generate a non-fungible token (NFT) on a blockchain that corresponds to an authenticated item for sale at the online marketplace. An NFT may indicate the unique characteristic of the item that was identified during the authentication process. A purchaser on the online marketplace may search for a given type of item. In response, the online marketplace searches the blockchain for NFTs that match the search and returns item listings based on the matched NFTs as well as authentication records for the item listings based on the NFTs. In some cases, a user may search for an item with a specific unique attribute, and the online marketplace may search for an NFT that indicates the corresponding item has that unique attribute.

Abstract: A physical storage vault for physical items of digital twin NFTs is described. A combined listing for a physical item and an NET of the physical item is generated, and the combined listing is output in a user interface at a client device. The user interface includes an option to store the physical item in a physical storage vault. A request is received from the client device to transfer ownership of the physical item and the NFT of the combined listing to a user account. The request indicates that the option to store the physical item in the physical storage vault is accepted. Responsive to the request, transfer of ownership of the NET to the user account is initiated by encoding metadata of the NFT on a blockchain with an identifier associated with the user account and by storing the physical item in the physical storage vault.
