Heterogeneous Paxos

Authors: Isaac Sheff, Xinwen Wang, Robbert van Renesse, and Andrew C. Myers

Published in: LIPIcs, Volume 184, 24th International Conference on Principles of Distributed Systems (OPODIS 2020)

Abstract
In distributed systems, a group of learners achieve consensus when, by observing the output of some acceptors, they all arrive at the same value. Consensus is crucial for ordering transactions in failure-tolerant systems. Traditional consensus algorithms are homogeneous in three ways: - all learners are treated equally, - all acceptors are treated equally, and - all failures are treated equally. These assumptions, however, are unsuitable for cross-domain applications, including blockchains, where not all acceptors are equally trustworthy, and not all learners have the same assumptions and priorities. We present the first consensus algorithm to be heterogeneous in all three respects. Learners set their own mixed failure tolerances over differently trusted sets of acceptors. We express these assumptions in a novel Learner Graph, and demonstrate sufficient conditions for consensus. We present Heterogeneous Paxos, an extension of Byzantine Paxos. Heterogeneous Paxos achieves consensus for any viable Learner Graph in best-case three message sends, which is optimal. We present a proof-of-concept implementation and demonstrate how tailoring for heterogeneous scenarios can save resources and reduce latency.

A Tour of Gallifrey, a Language for Geodistributed Programming

Authors: Mae Milano, Rolph Recto, Tom Magrino, and Andrew C. Myers

Published in: LIPIcs, Volume 136, 3rd Summit on Advances in Programming Languages (SNAPL 2019)

Abstract
Programming efficient distributed, concurrent systems requires new abstractions that go beyond traditional sequential programming. But programmers already have trouble getting sequential code right, so simplicity is essential. The core problem is that low-latency, high-availability access to data requires replication of mutable state. Keeping replicas fully consistent is expensive, so the question is how to expose asynchronously replicated objects to programmers in a way that allows them to reason simply about their code. We propose an answer to this question in our ongoing work designing a new language, Gallifrey, which provides orthogonal replication through _restrictions_ with _merge strategies_, _contingencies_ for conflicts arising from concurrency, and _branches_, a novel concurrency control construct inspired by version control, to contain provisional behavior.

07091 Abstracts Collection – Mobility, Ubiquity and Security

Authors: Gilles Barthe, Heiko Mantel, Peter Müller, Andrew C. Myers, and Andrei Sabelfeld

Published in: Dagstuhl Seminar Proceedings, Volume 7091, Mobility, Ubiquity and Security (2007)

Abstract
From 25.02.2007 to 02.03.2007, the Dagstuhl Seminar 07091 ``Mobility, Ubiquity and Security'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

Civitas: A Secure Remote Voting System

Authors: Michael Clarkson, Stephen Chong, and Andrew Myers

Published in: Dagstuhl Seminar Proceedings, Volume 7311, Frontiers of Electronic Voting (2008)

Abstract
Civitas is the first implementation of a coercion-resistant, universally verifiable, remote voting scheme. This paper describes the design of Civitas, details the cryptographic protocols used in its construction, and illustrates how language-enforced information-flow security policies yield assurance in the implementation. The performance of Civitas scales well in the number of voters and offers reasonable tradeoffs between time, cost, and security. These results suggest that secure electronic voting is achievable. The name of this system as presented at Dagstuhl was CIVS. In August 2007, the name was changed to Civitas. For more information, see the Civitas website at http://www.cs.cornell.edu/projects/civitas.
