We deliver hardware blockchain nodes installed at your premises and connecter to the systems or appliances. Those low power units are enabled with cable or radio interfaces to talk to the counters, sensors, actuators or controlling directly wall outlets.
Main part of the blockchain infrastructure of private type is in the cloud or at the central location and accessible to the remote nodes.
You and your customers access the system with DApps (special web pages in the browser) or dedicated mobile apps for the convenience. If needed there is a possible bridge to your centralised message processing unit to combine information from remote processes for supervision or top level control.
