An important objective of Blockchain verte project is to develop an application that provides its users (researchers and simple citizens) with a visualization service and an audit service. The visualization service allows for visualizing three main points of interest: CO2 measurements produced by the atmobox system, the notarization status of each file produced by said system, and the blockchain energy cost of the said notarization. The audit service complements the blockchain notarization service, allowing any user to download the measurement data and perform an audit to verify the integrity of the collection and processing workflows, using the notarized data as its frame of reference.
The application developed allows its users to configure five types of widgets and combine them into dashboards, to visualize data about specific atmoboxes in timeframes of interest. Widgets give a preview of the data they visualize on the dashboard, and can be opened (via the “view more” button) to reveal more details and configuration options. The dashboard configuration, including the position and the specific options provided for each widget, are saved individually for each user and persist between their respective sessions. We present in Figure below one example arrangement of a dashboard with one instance of each widget type.

The following is a non exhaustive list of widget types and their usage:
