This dissertation is about the blockchain technology and its impact on collaboration. So, there will be a research about different kinds of implementations and use cases of this innovative technology with a socio-technical view on it. As blockchain is a community-driven technology, it is needed to get more insights into those communities and how they are involved in the development process. In another step, it is planned to build an own demonstrator for supporting collaboration based on blockchain technology. This has the be evaluated using the design case study. The design process and use case are based on the results/findings of the insights into those different types of blockchain technologies and its communities.
