Title: DCEP-Sim: An Open Simulation Framework for Distributed CEP - Introduction for Users and Prospective Developers

Presenters: Fabrice Starks (University of Oslo, Norway), Stein Kristiansen (University of Oslo, Norway), Thomas Plagemann (University of Oslo, Norway)

Abstract: Evaluation of Distributed Complex Event Processing (CEP) systems is a rather challenging task. To simplify this task, we developed the open simulation framework for Distributed CEP, called DCEP-Sim. The goal of this tutorial is to facilitate the process of using DCEP-Sim. Since DCEP-Sim is designed and implemented in the popular network simulator ns-3 we introduce the most important concepts of ns-3. Simulations in ns-3 are configured and executed though a main program called an ns-3 script. We use a simple example script to explain how simulations with DCEP-Sim are set up and executed. To give an idea how DCEP-Sim can be adjusted to particular needs, we explain how DCEP-Sim can be adapted (e.g., through changing the workload and the network topology) and how new Distributed CEP solutions can be added by explaining how to add a new operator to DCEP- Sim.

Title: Deconstructing Blockchains: Concepts, Systems, and Insights

Presenters: Kaiwen Zhang (École de technologie supérieure, Canada), Roman Vitenberg (University of Oslo, Norway), Hans-Arno Jacobsen (University of Toronto, Canada and Technical University of Munich, Germany)
Date: 26.06.2018, 9.00 - 17.00
Location: MSC 1.20

Abstract: Popularly known for powering cryptocurrencies such as Bitcoin and Ethereum, blockchains is seen as a disruptive technology capable of impacting a wide variety of domains, ranging from finance to governance, by offering superior security, reliability, and transparency in a decentralized manner. In this tutorial presentation, we first study the original Bitcoin design, as well as Ethereum and Hyperledger, and reflect on their design from an academic perspective. We provide an overview of potential applications and associated research challenges, as well as a survey of ongoing research projects. We mention opportunities blockchain creates for event-based systems. Finally, we conclude with a walkthrough showing the process of developing a decentralized application (DApp), using a popular Smart Contract language (Solidity) for the blockchain platform of Ethereum.
