Threshold Logical Clocks

Solving the consensus problem in a new way by creating a global clock

An attempt to simplify asynchronous consensus by building atop a novel threshold logical clock abstraction, which enables upper layers to operate as if on a synchronous network. This approach yields an asynchronous consensus protocol for fail-stop nodes that may be simpler and more robust than Paxos and its leader-based variants, requiring no common coins and achieving consensus in a constant expected number of rounds.

The DEDIS team is working on projects related to large-scale collective authorities (cothorities), which distribute trust among a number of independent parties to allow scalable self-organizing communities. With no single trusted party, cothorities can secure software updates, provide public randomness, enable privacy-conscious medical-data sharing and a lot more. Other projects include communicating securely over insecure channels and fast, scalable, accountable anonymous communication.
