Sebastian Henningsen

I am a researcher at the Weizenbaum-Institute, in an interdisciplinary group working on Cryptocurrencies and Blockchains. Before starting my PhD I obtained a B. Sc. and M. Sc. in computer science from the University of Technology in Kaiserslautern where I was associated with the distributed computer systems (DISCO) group.

My PhD focusses on algorithmic central banking and security of Blockchain-Systems.

Find me on DBLP and LinkedIn.

Interests

  • Cryptocurrencies & Blockchain
  • Security and Privacy
