Abstract

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.
