Patent attributes
Techniques are described for managing devices, such as Internet of Things (IoT) devices, using smart contract(s) on a distributed ledger (e.g., blockchain). Smart contract(s) executing on a distributed ledger may control access to one or more devices in a home or other environment. The smart contract(s) may employ information stored on the distributed ledger and information in a transaction sent to the smart contract(s) to determine whether particular user(s) and/or process(es) may access the device(s), issue commands to the device(s), access data generated by the device(s), and/or control the device(s). The smart contract(s) may provide a secure portal through which user(s) and/or service(s) may access device(s) for command and control of such device(s), and secure access may be based on permission information that is specified or provided by an owner or operator of the device(s) and that is stored on the distributed ledger.
