 \maketitle
 
 \begin{abstract}
+  Privacy-preserving donations have complex requirements that also
+  vary by country. Building on privacy-friendly digital cash protocols
+  (which enable customers to pay anonymously using blind signatures)
+  we created the {\em Donau} system to handle key use-cases for donations.
+  This paper explains how our Free Software implementation addresses the
+  most common requirements, and also elaborates how others could be
+  instantiated with significant changes or additions to the design.
+
+  The Donau system achieves privacy for donors while providing
+  them with a proof that they donated to some registered charity.
+  The charity does not learn the identity of the donor and the tax
+  authority does not learn which charities received donations from
+  a particular donor. However, authorities do learn the total amount
+  donated to a charity by all donors.
+
+  Our design introduces a new entity, the {\em Donation Authority}
+  which operates the {\em Donau} service. The {\em Donau} would typically
+  be operated by or on behalf of the tax authority and ensures that
+  only recognized charities can register and provide proofs to their
+  donors.
+
+  Society would benefit from the Donau system as it simplifies
+  filing taxes, contributes to fair taxation, and eliminates
+  privacy-concerns from charitable giving.

 third parties but even to merchants and banks involved. While this payment
