A cоmmоn methоd for creаting а Verifiаble Random Function is to hash the output of a digital signature scheme.  So if (sk,vk) is a key pair for a digital signature scheme, we can define a function: Fsk(x) = H( signsk(x) ).  Algorand implements a VRF like this using ED25519, and Ethereum’s RANDAO implements a VRF like this using BLS signatures.  What would be the problem with implementing this using ECDSA?
