ブロックチェーン対応サービスプロバイダシステム

Japanese Patent JP7308756

B2

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.
