MARK.SPACE is an open source platform for creation of 3D/VR spaces and objects of any purpose, as well as their quick launch and integration into a unique ecosystem. The platform is maintained by a crypto economy and is powered by the Blockchain. MARK.SPACE supports all internet browsers (preferably Chrome) and, at the same time, is compatible with CardBoard, Oculus and HTC Vive. A desktop PC is all that is needed to create a state-of-the-art VR store, office, community or other space for either business or entertainment. The MARK.SPACE universe is made up of a great amount of VR spaces (units), where each unit can be linked directly to its own top-level domain. The private property of units is guaranteed by recording all transactions with units (to create, sell or rent) on the blockchain. All unit owners may buy, sell and/or rent their units to others through use of smart contracts. MARK.SPACE has its own MARK token (MRK), a utility token used as internal currency. The MRK token enables all users to sell and buy VR units and objects, consume various goods and use services, pay salary to their employees and buy ads to promote their businesses through the platform. GPU-miners who will be rendering VR spaces and objects for the platform’s users will also receive rewards in MRK tokens (POW conception).
