Introduction
My current research interests are into blockchain-based applications in complex socio-technical systems in a diversity of domains, in particular logistics, e-government, circular economy and blockchain for societal benefits (e.g. self-sovereign identities). The research is based on empirical cases, but the objective is to develop conceptual frameworks that are generic. Special attention is to the governance of these blockchain-based applications and how to align stakeholder interests.

Many of today’s essential services depend on infrastructure-based systems such as the energy, the telecommunications and the public transport system. These systems consist of interdependent subsystems that coevolve over time. The governance of these systems is performed by many different types of public and private actors. In addition these systems...

Following open data policies worldwide, an increasing number of public organisations has now published open data that is free to be used by anyone. However, despite the significant increase in use of this open data, the open data providers are mostly not aware of their users and the way in which the data is actually re-used. This is rooted in the p...

The paper argues that a new category of infrastructures is emerging, user-driven, self-organizing and with de-centralized control: inverse infrastructures (IIs). IIs are not well-understood. Moreover, they represent a paradigm shift in infrastructure development. Their bottom-up development shows tension with the current socio-institutional framewo...
