About

Since August 2021, the group is tenured at the Faculty of Business, Economics and Informatics, as the “Blockchain and Distributed Ledger Technologies” group. With this, UZH demonstrates a strong strategic interest in the area of Blockchain.

The group was born in 2015 as Network Science, within the University Research Priority Programme on Social Networks of the University of Zurich. Since the beginning, it brought an interdisciplinary breath to the activities of the Centre.

It established new areas of research and leveraged a large network of international collaborations.
The group has continuously grown, having seven PhD students (one more beginning in the following months), two post-doctoral researchers and two affiliated scholars. Expertise spans several fields such as network and data sciences, agent-based modelling, systems design, game theory and quantitative finance.

and growing.

We have developed an extensive research record around blockchain. We stand that DLT-based systems are paramount examples of complex socio-economic-technical systems. The large-scale properties
they evince non-trivial properties that can only be understood by comprehending the link between microlevel
the behaviour of the multiple, heterogeneous agents that compose them.

To achieve these goals, we perform large-scale data analysis and minimalistic modelling to uncover mechanisms behind observed regularities. As such, we are among the leading research groups for interdisciplinary approaches to studying Blockchain and DLT-based systems.
