Abstract
Technologies are shown for tracking transfer of an item on an item tracking data blockchain, where transfers of the item and the holder of the item are recorded in item tracking data blocks of the blockchain. In some examples, a verification of the item is performed for a transfer and recorded in the data block for the transfer. In other examples, the blockchain stores a unique code for the ticket. Transfers of the ticket are recorded in the blockchain. When the ticket is presented for use, a holder identifier and a presented ticket code are validated against a holder identifier in the most recent block in the blockchain and the unique code for the ticket stored in the blockchain. In some examples, a portion of a resale price of the ticket is sent to an issuer of the ticket.
