Description

The green blockchain moonshot demonstrates the use of a low energy blockchain as backbone of new notarisation and auditability services for climate data. The goal of the demonstrator is twofold : to highlight the low energy consumption achieved by CEA-engineered blockchains and to demonstrate the value brought by a secure blockchain to data that must be trusted by the public. Our use case relates to data collection and treatment of a set of CO2 sensors deployed in Paris urban area.Those data are today collected by the LSCE laboratory and treated through dedicated algorithms to establish correct CO2 measures.

We aim at making the whole data collection and treatment process a trustable process. To this aim, data are securely notarized in a blockchain to allow the general public (ranging from researchers to simple citizens) to audit the data whenever they want: establish the origin and methods used for their collection and treatment. Concretely, through a dashboard, users can visualise and audit data. When the audit starts, original and authenticated data and scripts are retrieved to allow re-playing the whole computation (from raw data to visualised data). Audit is possible because blockchain-based checks are in place to establish data integrity and authenticity. The dashboard visualises as well the energy consumed by the blockchain to notarize data.
