EdDSA, standardized by both IRTF and NIST, is a variant of the well-known Schnorr signature based on Edwards curves, and enjoys the benefit of statelessly and deterministically deriving nonces (i.e., it does not require reliable source of randomness or state continuity). Recently, NIST calls for multi-party threshold EdDSA signatures in one mode of deriving nonce statelessly …
