SchnorrQ: Schnorr signatures on FourQ

SchnorrQ is a digital signature scheme that is based on the well-known Schnorr signature scheme combined with the use of the elliptic curve FourQ.

SchnorrQ offers extremely fast, high-security digital signatures targeting the 128-bit security level. It was designed by instantiating (with minor modifications) the recent EdDSA digital signature specifications on a superior, state-of-the-art elliptic curve, FourQ. Similar to Ed25519, public keys are 32 bytes and signatures are 64 bytes.
