SBA Research is a research center for Information Security funded partly by the national initiative for COMET Competence Centers for Excellent Technologies. Within a network of more than 70 companies, 15 Austrian and international universities and research institutions, and many additional international research partners we jointly work on research challenges ranging from organizational to technical security to strengthen Europe’s Cybersecurity capabilities.

A Wild Velvet Fork Appears! @ FC´18 Bitcoin Workshop

The paper “A Wild Velvet Fork Appears! Inclusive Blockchain Protocol Changes in Practice” by Alexei Zamyatin, Nicholas Stifter, Aljosha Judmayer, Philipp Schindler, Edgar Weippl and William J. Knottenbelt, in cooperation with the Imperial College Centre for Cryptocurrency Research and Engineering (IC3RE), was presented at the 5th Workshop on Bitcoin and Blockchain Research at the Financial Cryptography and Data Security Conference 2018.


The loosely defined terms hard fork and soft fork have established themselves as descriptors of different classes of upgrade mechanisms for the underlying consensus rules of (proof-of-work) blockchains. Recently, a novel approach termed velvet fork, which expands upon the concept of a soft fork, was outlined in [22]. Specifically, velvet forks intend to avoid the possibility of disagreement by a change of rules through rendering modifications to the protocol backward compatible and inclusive to legacy blocks.

We present an overview and definitions of these different upgrade mechanisms and outline their relationships.
Hereby, we expose examples where velvet forks or similar constructions are already actively employed in Bitcoin and other cryptocurrencies. Furthermore, we expand upon the concept of velvet forks by proposing possible applications and discuss potentially arising security implications.

Pre-print version

Following a report on Bitsonline, Butarin commented on our research ‘In my lingo this would be “agreeing on a different state transition function”; I would say it’s definitely a useful kind of fork.’ (reddit)

SBA supports ABC – Austrian Blockchain Center

true to our vision statement, being the crystallization point of security research in Austria, we support the proposal for a new K1 research center. SBA Research (Edgar Weippl) coordinates jointly with the University of Vienna (Stefanie Rinderle-Ma) the fundamental research activities in Area 2 “Cryptography, Technology & Security”. (ABC, derBrutkasten).

Dagstuhl “Blockchains, Smart Contracts and Future Applications”

Everything is set up for April and we’re looking forward to meeting great people for exciting discussions.

IoT4CPS Public Kick-off

The public kick-off of the Austrian flagship project IoT4CPS took place at TU Vienna on February 1, 2018.

After some welcome notes from Johannes Fröhlich (Vice Rector, TU Vienna), Helmut Leopold (Head of Center for Digital Safety and Security, AIT) and Andreas Eckel (Team Lead Grants, TTTech) we looked into the contents and aims of the project.

The auditorium was then invited to join interactive workshops (one of them led by Katharina Krombholz, SBA) based on the project´s main topics. The official part of the kick-off was eventually concluded by short presentations of the brainstorming outcomes and an expert panel discussion.


FIT 2018 – Security

Today we presented how exiting it can be to study information security. Katharina Pfeffer and Edgar Weippl gave an introduction to cryptography and showed how hackers are portrayed in movies in contrast to how they really work. FIT (Frauen in die Technik) is an initiative to encourage female high school students to chose technical programs at universities.
