Citizen participation in Germany today is often slow and cumbersome – and for many citizens, it remains unclear whether their voice actually makes a difference. At the Digital Participation Lab, Jeannette Gusko and Leon Erichsen are building the technological infrastructure for what they call a participation stack. They are testing it in concrete use cases together with public administration and government in real-world operation. The stack includes Virtual Assemblies, Digital Citizen Hotlines, goal-oriented participation processes, and Quadratic Voting – formats that make participation faster, more efficient, and more effective. The role models are the Baltic states and Taiwan: in Taiwan, according to former Digital Minister Audrey Tang, trust in government rose from nine to over 70 percent in parallel with the rollout of digital participation tools. The goal is a new participation standard for Germany and Europe – fast, efficient, and sovereign.
