datadata VRFUsage

Indicate the usage of the VRF result.

VRFLeader
The VRF value will be used to establish whether the issuing node is indeed a leader for this slot.
VRFNonce
The VRF value will be used to contribute to the evolving nonce.

valuemkInputVRF

Construct a unified VRF value

valuevrfLeaderValue :: proxy c -> CertifiedVRF (VRF c) InputVRF -> BoundedNatural

Range-extend a VRF output to be used for leader checks from the relevant hash. See section 4.1 of the linked paper for details.

valuevrfNonceValue :: proxy c -> CertifiedVRF (VRF c) InputVRF -> Nonce

Range-extend a VRF output to be used for the evolving nonce. See section 4.1 of the linked paper for details.
