I've thought about this.

The list includes:

Sensors that sell data to computer stations in real time.
Sensors that buy analytical capabilities of computing stations.
Consumers who buy electricity from those who produce electricity.
Devices that buy storage space.
Devices that buy bandwidth on demand without the need for subscriptions.
Ensuring data integrity for IOT devices.
Providing an event-safe event register for any type of infrastructure.
Electronic voting and management.
