+<h1>2022-9: &quot;Zero-Knowledge Age Restriction for GNU Taler&quot;</h1>
+  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 
+  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 
+  instantiated with ECDSA as well with a variant of EdDSA, respectively, and 
+  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.
