  We introduce Unity, a new consensus algorithm for public blockchain settings.
Unity is an eventual consistency protocol merging the Proof-of-Work (PoW) and
Proof-of-Stake (PoS) into a coherent stochastic process. It encompasses
hardware and economic security without sacrificing availability,
unpredictability and decentralization. Empirical results indicate that the
proposed protocol is fair and scalable to an arbitrary number of miners and
stakers.
