XPX is the native currency of the ProximaX Sirius infrastructure and development platform. Network contributors and solution providers need XPX to stake and pay for the platform's multiple services: blockchain, storage, Supercontract, and streaming. ProximaX's tokenomics is extensive, demonstrating for the first time that any service, whether it be for storage, conference calls, or payments, can be provided for a fee. Stable currencies can be included in the future to extend the services beyond the ProximaX realm to capture a broader user base while still maintaining XPX as the anchor and native currency.
