Blockchain-implemented method and system

Abstract

The invention provide a blockchain-implemented control method and corresponding system(s). The invention may be arranged to control access to and/or use of an interne-enabled resource such as for example an IoT device. The resource may be a device or system. It may, for example, be a vehicle such as a driverless taxi or car. The vehicle may be provided with computing capabilities to enable it to communicate with other computer-based resources and/or interact with a distributed ledger. This distributed ledger may be a blockchain, such as, for example, the Bitcoin blockchain. In one embodiment, the invention provides a method for controlling the use of an interne-enabled resource comprising the steps of: providing a first blockchain transaction comprising at least one output which is redeemable only by provision of at least: i) a secret value selected by a user; and ii) a signature associated with a resource provider; sending use-related information to the resource; generating a second blockchain transaction requesting at least the secret value; and modifying the second blockchain transaction to include the secret value.
