Hyperion, a decentralized map platform, aims to achieve the “One Map” vision - to provide a unified view of global map data and service, and to make it universally accessible just like a public utility for 10B people. Built on the Spatial Consensus Protocol which encloses not just spatial information but also value transfer, Hyperion fundamentally redefines the way to create and consume map services, conforming to its first principles to make maps aggressively open and decentralized.
