6 quorums from an example consensus I consider interesting

Heterogeneous Consensus

The Heterogeneous Consensus project has invented and implemented a Consensus algorithm in which not all participants agree on who may fail, and how. We in some ways resemble the Stellar project, but our algorithm tolerates mixed Byzantine and Crash failures, one message-send lower latency, and a different model of Observers and Participants.

The first consensus algorithm with heterogeneous failures, heterogeneous participants, and heterogeneous observers.

We use the Decentralized Label Model to show how distributed algorithms, like Bosco and Nysiad, can be generalized from more complex trust environments.

Talks

With Charlotte, we can append one block onto multiple blockchains, solving the atomic commit problem.

A work-in-progress talk about our Heterogeneous Consensus algorithm.

We’ve been looking at modeling distributed system failures with information flow tools, and expressing heterogeneous trust.
