[GNUnet-developers] VRFs

VRFs are interesting critters:

"Unlike traditional digital signature algorithms, VRF outputs can be published 
publicly without being subject to a preimage attack, even if the verifier knows 
the public key (but not the proof). This is useful to prevent enumeration of 
the names/identifiers in a directory which is using a transparency system.”

They are basically deterministic signatures like RSA or BLS with a hash 
function applied, that one models as a random oracle.
