Abstract:

The disclosed technologies include receiving a request from a second computing device to verify ownership of a blockchain address. A challenge content is generated and sent to the requestor. A signature is received comprising a hash of the challenge content generated using a private key. A public key corresponding to the private key is obtained, and the signature is validated using the public key. In response to validating the signature, a characteristic is associated with a user associated with the blockchain address.

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:

Techniques for automatically modulating a physical configuration of a reconfigurable building structure. A reconfigurable building structure may be constructed of physical elements that are movable with respect to one another to facilitate actuating the reconfigurable building structure between a plurality of different physical configurations. The physical configuration of a reconfigurable building structure may be adjusted to accommodate for physical dimensions of an item that is going to be moved into the reconfigurable building structure. For example, a spacing between two shelves may be expanded in response to an order being placed for a large item. In this way, when the item is delivered to a physical address associated with the reconfigurable building structure, various physical characteristics of the reconfigurable building structure may have already been modulated to accept the item.

Abstract:

Technologies are shown for managing stored value on a blockchain involving creating a stored value contract block on a blockchain having an identifier of a first entity and code for transferring a portion of a stored value to a designated party. Funds data is stored to the blockchain indicating the stored value committed to the stored value contract block by the first entity. Code is invoked with an identifier of a second entity to transfer a portion of the stored value to the second entity. Some examples involve an intermediary entity verifying conditions defined in the stored value contract block in order to complete transfer. Other examples involve an intermediary entity monitoring conditions in order to initiate transfer when the conditions are satisfied.
