The second blockchain demo consists of three applications. The first is a simple UI that displays the current component state and allows the user to set the desired state for this component, namely either "on" or "off". The second application is a daemon that controls the component. This can either be a virtual application, or it can be deployed on a Raspberry Pi Zero W to control a relay. The third application is a simple setup application, which can be used along with vctool to bootstrap the demo. More information about these applications can be found in their respective respositories.
The common component repository defines methods that can be used to create and sign transaction certificates for the transactions supported by this demo.
