Blockchain for citizens' participation in urban planning: The case of the city of Berlin. A value sensitive design approach

Abstract

The aim of the paper is to investigate how a blockchain-based platform for citizens' participation in urban planning should be developed adopting a Value Sensitive Design approach (VSD). VSD can be considered as an overarching methodological framework for new technologies development which takes into account moral and human values of all the direct and indirect stakeholders which might be impacted by the technology. By considering the perspectives of the different involved stakeholders, the paper specifically addresses the call for more research about blockchain-based services which adopts a human-centred approach instead of technocentric.The paper is based on the empirical analysis of a DApp called BBBlockchain which was specifically created with the purpose to improve citizens participation in urban planning decisions in two major residential development projects in Berlin, Germany. BBBlockchain is a proof of concept which is currently running on its own in-house test network but it can run on every EVM compatible blockchain. From the analysis of the information layer of participation, it can be argued that the most important values include transparency, inclusiveness and confidentiality.
