Decentralized Systems and Network Services Research Group

Under the term "Decentralized Systems and Network Services" we understand distributed and networked technical systems that span over more than one administrative domain. Hence, their operation depends on more than one party. Our research focuses on:

  • Blockchains, consensus and peer-to-peer networks
  • Network Security Monitoring
  • Secure and privacy-aware computing in partially trustworthy environments.

Understanding Blockchains: Lecture at VDE Mittelbaden on 24/03/2020 (cancelled)

Prof. Hannes Hartenstein will give a presentation at Hochschule Karlsruhe on the 24th of March 2020 at 5:30 PM with the title "Geglückte Verkettung von Zuständen: Blockchains Verstehen" (in German). In this lecture, the basic elements of blockchains will be explained in a generally understandable way and insights into the communication behavior in the Bitcoin network will be presented. Then, existing challenges and approaches to solutions, especially with regard to security and scalability, as well as the automatic execution of contracts on blockchains ("Smart Contracts") are considered. The lecture concludes with a socio-technical view on questions of power in blockchain-based systems. Further Informations at VDE Mittelbaden.
