Governments play an important role in ensuring the functioning of our societies (Zucker, 1986; Möhlman, 2018). This paper therefore seeks to better understand the implications, potential advantages, and disadvantages when governments take on certain roles towards or within the sharing economy. The paper will answer the following question: What is the role of governments in sharing economies to help ensure trust between users? In order to deepen this research question, the paper will elaborate on what the role of technology can be to ensure that government plays a role in ensuring trust in sharing economies. This paper contributes to policymaking by identifying the options governments have to build trust in sharing economies. In order to elaborate on the role of governments in ensuring trust for sharing economies, Power, today, comes from sharing information. Not withholding it. Keith Ferrazzi 'Digital platform in industrial symbiosis' deals with B2B information sharing and the role of government in creating an electronic platform to enable this. The second descriptive case study 'Blockchain in Peer-to-Peer Energy Trading' deals with P2P electricity trading and the role of government in enabling the sharing of electricity. It deals with security and privacy constraints in a blockchain network. Both use cases involve the region of Flanders, Belgium.
