  This paper discusses an open source solution to smart-parking in highly
urbanized areas. Interviews have been conducted with domain experts, user
stories defined and a system architecture has been proposed with a case study.
Our solution allows independent owners of parking space to be integrated into
one unified system, that facilitates the parking situation in a smart city. The
utilization of such a system raises the issues of trust and transparency among
several actors of the parking process. In order to tackle those, we propose a
smart contract-based solution, that brings in trust by encapsulating sensitive
relations and processes into transparent and distributed smart contracts.
