Query: Fair Proof-of-Stake using VDF+VRF Consensus   We propose a new Proof-of-Stake consensus protocol constructed with a
verifiable random function (VRF) and a verifiable delay function (VDF) that has
the following properties: a) all addresses with positive stake can participate;
b) is fair because the coin stake is proportional to the distribution of
rewards; c) is resistant to several classic blockchain attacks such as Sybil
attacks, "Nothing-at-stake" attacks and "Winner-takes-all" attacks. We call it
Vixify Consensus.
