Distributed energy trading settlement is provided. The method comprises polling a number of Internet-of-Things (IoT) devices for energy consumption and production data for a specified preceding time interval and receiving weather data from a weather application programming interface (API) for the same time interval. A number of bids and offers are received from a central modelling solution within a specified trading window, based on the data from the IoT devices and weather API. Orders are then created from the bids and offers. At least a subset of the orders are matched to create a number of matched trades, which are published to a message queue. The published matched trades are committed as transactions in a blockchain, and tokens are transferred between user wallets according to the transactions in the blockchain.

An electronic device that generates an electronic-device-specific application is described. During operation, the electronic device may receive a request to create the electronic-device-specific application, where the electronic-device-specific application is associated with a services manager in a system hierarchy. In response to the request, the electronic device may provide instructions for a user interface, wherein the user interface is configured to present predefined configuration alternatives for configuration parameters for the electronic-device-specific application and/or to receive inputs for the configuration parameters for the electronic-device-specific application. Then, the electronic device may receive user-interface activity information, which specifies selections of the configuration parameters for the electronic-device-specific application, where the configuration parameters for the electronic-device-specific application specify functions in a physical layer, a data link layer and a network layer in the electronic-device-specific application. Next, the electronic device may generate, based at least in part on the configuration parameters, the electronic-device-specific application.
