U.S. Patent 10652239 was awarded to SLOCK.IT GMBH on May 12, 2020 and is entitled “Block-chain enabled service provider system including permission data structure and state channel monitoring.” The first named inventor is Christoph Jentzsch of Mittweida, . The abstract contains an overview of the patent disclosure:

A distributed ledger, e.g., blockchain, enabled operating environment includes a user device that accesses services of a service device by leveraging the decentralized blockchain. For example, a user device can lock/unlock a door (e.g., service device) by interfacing with a smart contract stored on the decentralized blockchain. The user device provides parameters, such as payment, that satisfies the variables of the smart contract such that the user device can access the service device. The service device regularly retrieves information stored in the smart contract on the decentralized blockchain. For example, the retrieved information can specify that the user device is authorized to access the service device or that the service device is to provide a service. Therefore, given the retrieved information, the service device provides the service to the user device. Link to Full Patent
