    Data Governance Act Proposal
    (Weizenbaum Institute, 2021) Neuberger, Christoph; Friesike, Sascha; Krzywdzinski, Martin; Eiermann, Karin-Irene; Stocker, Volker; Schawe, Nadine; Efroni, Zohar; von Hagen, Prisca; Völzmann, Lisa; Müller, Ferdinand
    This Position Paper contains statements drafted by several Research Groups at the Weizenbaum Institute concerning the Data Governance Act (DGA) Proposal. Each statement is followed by a short explanation. The purpose of this Paper is to highlight a number of important aspects of the DGA Proposal and stimulate the debate around it with a special emphasis on the part that concerns regulation of data sharing services (Chapter III, DGA Proposal). The Paper touches upon a number of selected matters without the ambition to cover all the important issues the DGA legislation raises. The statements address the potential risks in creating a centralized architecture for data intermediaries, the problem of imposing a duty on data sharing services to offer data on a non-discriminatory basis, the role and expertise supervision authorities will need to assume and exercise and questions regarding the interface between the anticipated DGA and existing data protection law in the EU. The Paper includes a number of specific recommendations regarding the formulation of several DGA provisions, specifically in connection with its intersection points with the GDPR.

    Federated Blockchain Systems: A better trade-off between sustainability and decentralization?
    (Weizenbaum Institute, 2022) Florian, Martin
    Blockchain-based systems are enjoying unbroken popularity. Different economic and social actors are investigating their application for fostering decentralization and separation of power. Whether a blockchain-based system can live up to such goals is heavily determined by the choice of a consensus protocol – the rules by which participants agree on what gets added to the blockchain. Bitcoin’s consensus protocol is inherently decentralization-enabling, at a notoriously high ecological cost. So-called permissioned protocols, while incomparably more efficient, are dismissed as being closed-off and "centralized". Federated blockchain systems represent a middle ground between these two extremes and promise to offer openness and security without sacrificing ecological sustainability. As a rough approximation, their approach can be described as bootstrapping consensus from a web of trust. In this overview article, after a short review of the Bitcoin approach and possible alternatives to it, we introduce the ideas behind federated blockchain systems and discuss their impact on future blockchain systems.
