Abstract: Reaching consensus in a distributed system is one of the most fundamental problems studied in distributed computing. It is non-trivial due to uncertainties related to unsuccessful communication and process faults. In particular, the celebrated FLP impossibility result shows why scheduling an event via an asynchronous communication medium such as email is difficult. In this talk, I will present our recent results on exact and approximate consensus in hostile environments such as dynamic networks (e.g., due to mobility of agents) and synthetic bacterial cultures.
