Hello. My name is Martin Plattner. I am a student and software developer in Innsbruck, Austria.
I study Computer Science at the University of Innsbruck and I am expected to graduate in April 2020. During my masters I focused on IT security and data analysis, and have been working as a student assistant in the Security and Privacy Lab of Rainer Böhme. Currently I am completing my master thesis on cross-blockchain data analysis using BlockSci. Previously I completed bachelors in Computer Science and Business Informatics at the University of Vienna and did an exchange semester focused on applied digital forensics at the University of Stockholm.
I run a freelance software development and IT consulting business since 2011. I am specialized on the creation of custom (web) applications that efficiently support business needs. I cover all stages of a project and aim for close cooperation with the client to deliver high-quality results. My services also include the creation of websites, data analysis tasks, and general IT consulting. More about my services and a selection of previous projects can be found below. If you want to work with me, please send me an e-mail.
Interests. Software Development, IT Security, Data Analysis, Distributed Ledger Protocols, Graphic Design
# Academic Works
-
– Master Thesis: Generalizing BlockSci Analyses To Forked LedgersBlockSci is a high-performance in-memory blockchain analysis platform developed at Princeton University. I extended BlockSci to improve its support for forked ledgers like Bitcoin Cash. The extension enables cross-chain analyses that include data from multiple chains. I implemented cross-chain address clustering which improves the established single-chain approach to cluster addresses that are owned by the same users.

– Bachelor Thesis: Evaluation of Responsive Images Solutions for the WebIn this work I reviewed six responsive images solutions against a custom evaluation framework. The native HTML5 responsive images solution outperformed all the other methods. It was used in a case-example to create the travel catalogue destinat.io which uses responsive fullscreen images.
