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 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 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.

Abstract: Techniques for resource allocation with content creators are described that overcome the challenges of conventional techniques by supporting customized digital content generation and resource allocation specified by content creators of digital content. In one example, a content provider system, based on user input received via a control, specifies the portions of a resource allocation to be shared. A first portion is configured to be shared with a content creator of digital content, the digital content including service access data configured to access a digital service. A second portion is also configured to be shared with a client device that utilizes the service access data to access the digital service. Digital content is generated based on the specified portions and is transmitted. Upon access by the client device to the digital service, an indication of receipt of the first portion of the resource allocation is displayed by the content provider system.

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: Various methods and systems for providing predicted item conditions for items in an item listing system. A predicted item condition may indicate a calculated estimate of a descriptive state of the item based on item transaction features. Operationally, item transaction features of an item—associated with an item listing interface—are accessed at the item listing system. The item transaction features are communicated to an item condition prediction machine learning model of the item listing system. The item condition machine learning model is trained on historical item transactions comprising item condition features of historical item transactions, the historical item transactions are previous item transactions associated with the item listing system. Based on the item transaction features of the item, the item condition machine learning model is caused to generate a predicted item condition. The predicted item condition is communicated as a recommended item condition or required item condition.

Abstract: Various methods and systems for providing customized-item-specific interfaces of items on extended interface devices in a search system. A plurality of items—each having an extended interface configuration that indicates customized-item-specific interface instructions for extended presentation of items on extended interface devices—are accessed at a primary interface device associated with a set of extended interface devices including a second-user extended interface device that supports a social mode. Based on the first extended interface configuration of a first item, a determination is made that the first item is extendable to a first extended interface device in the set of extended interface devices. Based on determining that the first item is extendable, automatically causing generation of a customized-item-specific interface of the first item on the first extended interface device.

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: Enhancing enterprise security by deploying a robotic security escort to guide a guest along a route that is tailored to the guest to ensure that the guest does not pass through restricted areas which the guest is not authorized to access. The guest may be assigned a security authorization level that defines whether the guest is permitted to access one or more predefined areas of the enterprise facility. A destination location to which the guest is to be escorted may be identified. Based on the security authorization level assigned to the guest, the system determines an appropriate route for escorting the guest throughout the enterprise facility to the destination location. The system may then deploy the robotic security escort to physically escort the guest along the appropriate route obtain adequate security with respect to sensitive enterprise resources while the guest is visiting the enterprise facility.

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.
