The SCDI BlockChainLab will host the first of a set of annual blockchain hackathons at the Offentliga Rummet conference in Gothenburg, May 24-25. The idea is to get groups together all over Sweden to participate in challenging the public sector through blockchain applications. The winning price is seed money from Vinnova that will allow the winning solution to be realized.
