VRF Proof

Fields§

Implementations§

source§

impl VrfProof

source

pub fn prove(x: SecretKey, alpha_string: &[u8]) -> Self

Execute the VRF function and create a proof given a SecretKey and a seed input alpha_string.

source

pub fn verify(&self, Y: PublicKey, alpha_string: &[u8]) -> bool

Verify a VrfProof given a Publickey and a seed input alpha_string.

source

pub fn hash_output(&self) -> Hash

Returns the VRF output. It is necessary to do VrfProof::verify first in order to trust this function’s output. TODO: FIXME: We should enforce verification before getting the output.
