Short DescirptionThe objective of Open Call #5 is to employ digital identities, trustworthy data, and already designed novel mechanisms for the ecosystems’ economy, in order to achieve high energy efficiency and optimisation of particular DLTs. We are looking for the most appropriate, relevant and pertinent tradeoffs between the use of technologies, the security of consensus protocols on one side, and the sustainability requirements on the other. A user-centric design, focused on energy efficiency, trustworthiness, and scalability, will guide the development of solutions. Privacy by design, greenness, openness, and legal compliance should be carefully considered.
