+\section{Motivation}
+Donations can often be deducted from taxes. To do so, donors must submit
donation receipts to the tax authorities. Nowadays, donation receipts can only
be checked with disproportionate effort. This is the reason why receipts for
small amounts are often not checked at all. Furthermore, donations are
sensitive data that should be anonymized as much as possible. Even towards the
tax authorities. For example, a donation to an AIDS aid organization can lead
to conclusions that could be unplea [...]
+
+\section{Goals}
+The project description is as follows:
+The goal of this project is to add anonymous donation receipts to Taler.
Someone donating to a
+charitable organization may wish to do so anonymously, but still want to
deduce that amount of
+their tax. This can be done by reusing cryptography present in Taler.
+A great part of the project will be specifying the details, as well as
implementing the Donau
+(Donation authority). Furthermore, the Taler merchant part and the wallet will
have to be
+developed/adapted. Optionally, a small Android donation verification app will
also be provided.
-The Donau is a Taler extension which should make it possible to make donations
anonymously, but the amount of the donation should be able to be proven to the
tax authorities. Similar to the Taler exchange, the Donau has the Donation
Authority (or Donau for short). The Donau blindly signs the charity's donation
receipts request. For submission to the tax authorities, the donor must submit
the donation receipts to the Donau, whereupon the donor receives the donation
statement (signature), [...]
-\\
-This concept, which has not yet been finalized, is discussed in more detail in
the following pages. The API definition, written by us, can be found under this
link: \url{https://docs.taler.net/core/api-donau.html}.
