...Currently the solution of choice is to use a light client or remote client on mobile devices. While this may work for mobile phones, most IoT devices are unable to run light clients. Connecting an IoT device to a remote node enables even low-performance IoT devices to be connected to blockchain. However, by using distinct remote nodes, the advantages of a decentralized network are undermined introducing a single point of failure. Also, it is unsecure because the client is not able to verify the results by itself. The same applies for mobile apps or web pages.
