10:00am - Welcome Coffee

10:30am - 12:30am - Conferences

"BFT, Blockchain and Beyond", by Ittai Abraham , VMWare

  • What is a Blockchain? What does decentralized trust mean? What is the difference between Proof-of-Work, Proof-of-Stake and Proof-of-Membership? How is Byzantine Fault Tolerance (BFT) related to Blockchains?  In this talk, I will try to provide some answers to these questions by using the lens of the foundations of Distributed Computing.  Time permitting I will also survey the emerging research frontier looking at new hybrid solutions that combine both classic and modern approaches.

"Anonymity in Cryptocurrencies?", by Sarah Meiklejohn, University College London

  • A long line of recent research has demonstrated that existing cryptocurrencies often do not achieve the level of anonymity that users might expect they do, while at the same time another line of research has worked to increase the level of anonymity by adding new features to existing cryptocurrencies or creating entirely new cryptocurrencies.  This talk will explore both of these lines of research, demonstrating both de-anonymization attacks and techniques for anonymity that achieve provably secure guarantees.

12:30pm - 2:00pm  - Buffet lunch

2:00pm - 4:00pm - Conferences

"Distributed Blockchain Algorithms", by Maurice Herlihy, Brown University

  • In the future, there will be many blockchains.  Different institutions will require different blockchains to manage different resources, and even within a single institution it may make sense to split a blockchain into multiple shards (distinct co-operating chains) for load balancing, administrative ease, and security.
    To be successful, a multi-chain enconomy will require the ability to execute transactions that span mulitple blockchains.  As an example, we will review the problem of an atomic cross-chain swap, a distributed coordination task where multiple parties exchange assets across multiple blockchains, for example, trading bitcoin for ether. A cross-chain swap protocol must guarantee that (1) if all parties conform to the protocol, then all swaps take place, (2) if some coalition deviates from the protocol, then no conforming party ends up worse off, and (3) no coalition has an incentive to deviate from the protocol

"Measurements of Trustworthy Networked Systems" , by Georg Carle, Technical University of Munich

  • It is an important challenge to understand performance properties and scalability of distributed systems, in particular if these systems use complex security mechanisms, as it is the case for Blockchain systems.

    The talk describes approaches for measuring complex networked systems. One aspect is to use automated workflows to perform reproducible experiments in a testbed, yielding measurement data of high quality, suitable for benchmarking and modelling performance properties of trustworthy networked systems. Further aspects include investigations of different protocol mechanisms and configurations, and studying real-world deployments.

A closing reception will be given after the workshop.
