         As a payment system must still be legal to operate and use, it must comply
         with these requirements. Furthermore, we consider levying of taxes as
         beneficial to society.

       <p>
         This imposes requirements on the security of the system, as well as on the
         general design, as payment fraud can also happen through misleading user
         interface design or the lack of cryptographic evidence for certain processes.

       <p>
         The reason behind this goal is similar to (2). The privacy of buyers is given
         priority, but other parties such as merchants still benefit from it, for example,
         by keeping details about the merchant’s financials hidden from competitors.

       <p>
 Specifically it must be usable for non-expert customers. Usability also
 applies to the integration with merchants, and informs choices about the
 architecture, such as encapsulating procedures that require cryptographic
 operations into an isolated component with a simple API.

 Approaches such as proof-of-work are ruled out by this requirement. Effi-
 ciency is necessary for GNU Taler to be used for micropayments.

       <p>
 While the design we present later is rather centralized, avoiding single
 points of failure is still a goal. This manifests in architectural choices such
 as the isolation of certain components, and auditing procedures.
