+<h1>2022-9: "Zero-Knowledge Age Restriction for GNU Taler"</h1>
+
+<h2>Abstract</h2>
+<p>
+ We propose a design for a privacy-friendly method of age restriction in
+ e-commerce that is aligned with the principle of subsidiarity. The design
+ is presented as an extension of a privacy-friendly payment protocol with a
+ zero-knowledge scheme that cryprographically augments coins for this purpose.
+ Our scheme enables buyers to prove to be of sufficient age for a particular
+ transaction without disclosing it. Our modification preserves the privacy and
+ security properties of the payment system such as the anonymity of minors as
+ buyers as well as unlinkability of transactions. We show how our scheme can be
+ instantiated with ECDSA as well with a variant of EdDSA, respectively, and how
+ it can be integrated with the GNU Taler payment system. We provide formal
+ proofs and implementation of our proposal. Key performance measurements for
+ various CPU architectures and implementations are presented.
