Currently none. But if you are interested in a topic in the field of fault-tolerant consensus, replication mechanisms or distributed ledger technology, then contact christian.berger@uni-passau.de. You can present an own idea, or we may be able to find a topic that is fitting for you. A requirement is usually that you have either participated in the Cloud Computing seminar or Dependable Distributed Systems lecture.
