"Antrittsvorlesung: The Perennial Quest for Decentralization"

Many services are provided by one or a small number of entities. As a consequence, users are highly dependent on these entities and mainly have to accept the conditions under which the service is provided. Furthermore, if the entity becomes unwilling or unable to provide the service, users lack alternatives.

My research focuses on decentralized systems, which reduce or completely remove the dependency on central parties. While decentralization is desirable from an idealist perspective, practically, it comes with technical challenges regarding efficiency, reliability, security, and privacy as well as social, legal, ethical, and economic challenges.

In this talk, I will illustrate the challenges created by decentralization in general before diving into specific applications that I and my team are working on. In particular, I will talk about my past work on anonymity and censorship resistance using P2P networks, my work on blockchain scalability, and recent results on security in distributed machine learning. I furthermore will highlight how all these works still have inherent limitations, such as a reliance of internet infrastructure that might be blocked or destroyed. Based on the discussion of these limitations, I will lay out my future work as a professor at the RPTU Kaiserslautern-Landau.
