     A zone in GNS is defined by a public/private ECC key pair (d,zk),
     where d is the private key and zk the corresponding public key.
-    GNS combines the EC parameters of Ed25519 (<xref target="RFC8032" />)
+    GNS employs the curve parameters of the twisted edwards representation
+    of Curve25519 <xref target="RFC7748" /> (edwards25519)
     with the ECDSA scheme (<xref target="RFC6979" />).
     The deterministic property of ECDSA (as opposed to EdDSA) is required
     in order to achieve zone privacy.
