A special thank to Michiel Leenaars from the NLnet foundation who had the initial idea for the project.
We would also like to thank our expert Daniel Voisard for his feedback during the project.
Further we would like to thank Christian Blättler for his contributions to GNUnet, on which our project relies on.
A big thank to the tax authority Zürich who agreed to an interview, which has provided us with valuable insight in how donations are verified and important aspects that a system like the Donau should fulfill.
We would like to mention that we have used DeepL for word translations and \url{https://app.diagrams.net/} for some of the figures in this thesis.
