Erb, Benjamin; Meißner, Dominik
Blockchain Analysis with Chronograph
Bachelor's thesis, Master's thesis or individual lab project
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: PROJEKT, AA, BA, MA, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: Blockchain technology allows for decentralized, distributed, and secure ledgers that store records (e.g., transactions). Popular blockchain-based systems such as Bitcoin and Etherum have emerged as so-called crypto-currencies. As the ledger maintains the full history of transactions, interactions within the system are always persisted. In this work, the student is asked to design and implement online and offline transaction analyses based on Chronograph, a data processing platform for evolving graphs developed at our Institute. Therefore, different blockchain-based systems should be surveyed and appropriate analysis mechanisms should be conducted.

Dependency Tracking in Distributed Retroactive Applications
Bachelor's thesis, Master's thesis or individual lab project
Institute of Distributed Systems,
2018
in Vorbereitung

Marker: PROJEKT, AA, BA, MA, FrankKargl, retroaction, distributed, DominikMeissner

Zusammenfassung: Retroactive computing enables programmatical access to the history of an application. This offers a variety of capabilities, such as computations and predictions of alternate application timelines, post-hoc bug fixes, and retroactive state explorations. Reads and writes of the application state have to be tracked and persisted in order to support retroaction. This is fairly simple for a single-writer append-only log, but entails various issues in a distributed setting. This thesis/project should explore different approaches for a distributed dependency tracking, including a prototypical implementation based on an existing platform prototype and an evaluation of the resulting artifacts.

Pause/Shift/Resume in Chronograph
Bachelor's thesis or individual lab project
Institute of Distributed Systems,
2017
in Vorbereitung

Marker: PROJEKT, AA, BA, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: Pause/Shift/Resume is a mechanism for doing iterative graph processing on an evolving graph using snapshots. Our Chronograph graph processing platform provides very similar functionalities based on an event-sourced graph model. In this work, the student is asked to incorporate the Pause/Shift/Resume mechanism into our platform. Therefore, the mechanism has to be adapted and adjusted to event-sourced graphs. Furthermore, an evaluation should highlight the runtime behavior of the approach in different workloads.

Evaluation of Key/Value Stores for Event Sourcing
Bachelor's thesis or individual lab project
Institute of Distributed Systems,
2017
in Vorbereitung

Marker: PROJEKT, AA, BA, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: Event sourcing is an alternative persistence approach that maintains a log of state-changing events instead of altering states directly. Event-sourced architectures require an event store for efficiently appending and retrieving log entries. In this project, an evaluation of different key/value stores and alternative (No)SQL stores is to be conducted in order to identify stores appropriate for event sourcing.

Secondary Index Structures on Event-sourced Graphs
Bachelor's thesis or individual lab project
Institute of Distributed Systems,
2017
in Vorbereitung

Marker: PROJEKT, AA, BA, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: As part of an ongoing research project at our institute, we are currently developing a novel distributed computing platform prototype. The systems provides a graph-based, asynchronous programming model and takes advantage of event sourcing for history-aware computations. The aim of this student work is the identification and evaluation of appropriate secondary index structures, in order to provide fast access onto specific notes of the graph topology. Also, a prototypical implementation is part of this work.

Interactive exploration of event-sourced graphs
Master's thesis, Diploma thesis, or Project (8 or 16 ECTS)
Institute of Distributed Systems,
2016
in Vorbereitung

Marker: AA, MA, DA, PROJEKT, BenjaminErb, FrankKargl, sidgraph, distributed, DominikMeissner

Zusammenfassung: The chronograph platform is a system for computing on evolving graphs. One module of the platform should provide an interactive user interface for exploring the history, evolution, and topology of the graph. The goal of this project is the design and implementation of a scalable, web-based user interface for the exploration of chronograph data.

Individual Student Projects

Master Projects

I provide a number of  individual master projects that are related to my field of research. Several student thesis topics can also be worked on as part of a master project.

Most projects can be conducted as 8 LP or 16 LP projects, depending on the focus and extent of the topic.

For more details, please get in touch with me.
