    Opera is a scalable local simulation network for experimental researches on distributed systems. To the best of our knowledge, it is the first Java-based event-driven simulator for distributed systems with a modular network, induced churn and latency traces from real-world systems, full life cycle management of the nodes, and a production-grade simulation monitoring. In this demo paper, we present the key features of Opera, its software architecture, as well as a sample demo scenario.

    LightChain is the first Distributed Hash Table (DHT)-based blockchain with a logarithmic asymptotic message and memory complexity. In this demo paper, we present the software architecture of our open-source implementation of LightChain, as well as a novel deployment scenario of the entire LightChain system on a single machine aiming at results reproducibility.

    Demo: Skip Graph middleware implementation
    (Institute of Electrical and Electronics Engineers (IEEE), 2020) Department of Computer Engineering; Hassanzadeh-Nazarabadi, Yahya; Nayal, Nazir; Hamdan, Shadi Sameh; Şahin, Ali Utkan; Özkasap, Öznur; Küpçü, Alptekin; Faculty Member; Department of Computer Engineering; Graduate School of Sciences and Engineering; College of Engineering; N/A; N/A; N/A; N/A; 113507; 168060
    Skip Graphs are Distributed Hash Table (DHT)based data structures that are immensely utilized as routing overlays in Peer-to-Peer (P2P) applications. In this demo paper, we present the software architecture of our open-source implementation of Skip Graph middleware in Java. We also present a demo scenario on configuration and constructing an overlay of Skip Graph processes in a fully decentralized manner. Our implementation is capable of hosting data objects at the Skip Graph processes and serving as a P2P data storage platform as well. Our middleware implementation provides an open-source platform to support Skip Graph-based applications on top of it.
