Module sp_core::bandersnatch::vrf

Bandersnatch VRF types and operations.

Structs

• VrfInput
  VRF input to construct a VrfOutput instance and embeddable within VrfSignData.
• VrfOutput
  VRF (pre)output derived from VrfInput using a VrfSecret.
• VrfSignData
  A Fiat-Shamir transcript and a sequence of VrfInputs ready to be signed.
• VrfSignature
  VRF signature.

Constants

• MAX_VRF_IOS
  Max number of inputs/outputs which can be handled by the VRF signing procedures. The number is quite arbitrary and fullfils the current usage of the primitive. If required it can be extended in the future.

Type Definitions

• VrfIosVec
  Bounded vector used for VRF inputs and outputs.
