New patents are issued by the USPTO on Tuesdays. Both of today's Spotlight Patents continue the theme of blockchains (smart contracts, distributed ledgers) and rights management broadly construed. Assigned to Blockstream, the first patent addresses techniques for transferring ledger assets between blockchains via pegged sidechains. Assigned to Netspective, the second patent addresses techniques for a device-driven non-intermediated blockchain system over a social integrity network.
10,812,274, "Transferring ledger assets between blockchains via pegged sidechains," assigned to Blockstream Corporation.
Systems and methods are described for transferring an asset from a parent chain to a sidechain. A simplified payment verification (SPV) proof associated with the parent chain asset may be generated. The SPV proof may include a threshold level of work. The SPV proof associated with the parent chain asset may be validated, and a sidechain asset corresponding to the parent chain asset may be generated. If no reorganization proof is detected, the sidechain asset is released. To redeem the sidechain asset in the parent chain, a SPV proof associated with the sidechain asset may be generated. The parent chain may validate the SPV proof associated with the sidechain asset. The parent chain asset associated with the sidechain asset may be held for a second predetermined contest period. The parent chain asset may then be released if no reorganization proof associated with the sidechain asset is detected.
10,811,124, "Device-driven non-intermediated blockchain system over a social integrity network," assigned to Netspective Communications LLC
A blockchain configured device-driven disintermediated distributed system for facilitating multi-faceted communication over a network. The system includes entities connected with a communications network. Each of the entities and associated devices and sensors and networks serve as a source of data records. The system includes a blockchain configured data bank accessible by each of the plurality of entities based on rules and preferences of the entities upon authorization by the blockchain configured data bank. The blockchain configured data bank includes a processing component for executing stored instructions to process the data records of the entities over the communications network. The system includes a blockchain configured component communicatively coupled to the blockchain configured data bank and adapted to be accessible by each of the plurality of entities. The system includes a validation device including a facial expression-based validation device and a geo-tagging-based validation device.
