On October 19, our CEO Almudena de la Mata participated in the webinar Innovate with Blockchain. She presented our project DivAirCity, where we designed a DApp to improve air quality in five European cities (Castellón, Aarhus, Orvieto, Bucharest and Potsdam). The DApp uses blockchain technology to encourage the contribution of citizens to the improvement of air quality with changes in their behavior and a guarantee of privacy. Diversity criteria are applied with the aim of achieving a fairer result and higher levels of inclusion. In this project, funded by the European Commission, we work with co-creation methodologies to achieve digital solutions for cities (smart cities/govtech).
