Abstract: Technologies are shown for controlling a transaction on a blockchain. A first block is created on a blockchain for a transaction involving a seller entity associated with a first key, a buyer entity associated with a second key, and an intermediary entity associated with a third key. Funds for the transaction are associated with the first block. A second block storing refund code is created and linked to the first block. The refund code is executable to refund the funds when a seller digital signature using the first key and/or an intermediary digital signature using the third key are received. A third block storing payment code is created and linked to the first block. The payment code is executable to transfer the funds when a buyer digital signature using the second key and/or an intermediary digital signature using the third key are received.

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.

Abstract: Technologies are shown for controlling a transaction on a digitally stored blockchain by creating a contract data block for a transaction involving entities and by event code executed after receipt of digital signatures from the entities. A refund transaction may be digitally signed by entities and linked to the contract block within the blockchain. A payment transaction block may also be digitally signed by entities and linked to the contract block. Code authorized to execute by the blocks executes based on receipt of digital signature events.
