We first review a novel mining solution using the Proof of Useful Work (PoUW) consensus. We will explain the Multiple-Chain Structure and then describe how we plan to provide an generic interface for Town Crier, an authenticated data feed for smart con- tracts. We will also discuss how Ankr’s technologies will enable de- centralized cloud computing. Finally, we will characterize the Ankr Ecosystem and the app interface to further facilitate the utilization of the Ankr network. 2
