ECVRF

ecvrf^1 is elliptic curve verifiable random function that satisfies:

• trusted uniqueness ^2
• trusted collision resistance ^3
• full pseudo-randomness ^4

ECVRF protocol

Proof generation

$proof = prove(sk, data)$, sk is VRF private key, data is input data as stream of bytes, proof is the vrf output. generate a vrf proof, that can be publicly verified.

Proof verification

$verify(pk, proof, data)$, pk is VRF public key, validate that the proof is correct.
