To obtain access to goods or services between people or stakeholders, some collaboration between actors is a necessary component. Sharing and a sharing economy is closely related to trust. Within the context of 'the' sharing economy, especially digital trust is assumed to play a crucial role. Access to information is a crucial digital cue which can lead to trust yet, sharing economies are subject to asymmetry of information, wherein certain actors have limited access to market information on the consumption behaviour of users, the pricing of a product and, the reliability of peers. The lack of confidential market information between actors is thus limiting the potential for collaboration, as it reduces trust between them. Governments are amongst the (usually more trustworthy) candidates to undertake critical roles in enhancing the sharing of sensitive data. This paper aims to identify the role of government in facilitating and enabling data sharing between various actors in sharing economies. In this paper, we analyse the adequacy of a government's potential role in enabling transparency, trust and security, while operating within a sharing economy scenario, based on two case studies. Additionally, the role of technology is briefly defined for digital platforms and for blockchain-based opportunities for sharing economies. The use cases for the paper concern a digital platform for industrial symbioses, and peer-to-peer electricity trading based on blockchain technology.
