OVR is a World Scale, open-source, AR platform powered by Ethereum Blockchain. OVR makes it possible for users provided with a mobile device or smart glasses to live interactive augmented reality experiences customised in the real world. OVR can be defined as a new standard in augmented reality experiences by placing itself as the first content browser where the user does not choose the contents but the world submits the possible experiences based on its geographical position. OVR adopts the open source philosophy, meaning that the entire OVR community contributes to its growth, thus making the platform independent of its creators. OVR use Ethereum blockchain to decentralise all the token exchange dynamics between the users. OVR token is an utility token based on the Ethereum’s smart contract ERC-20 standard. OVRLands are parcels stored inside a blockchain-based ledger that make up the digital layer of subdivision of our planet into hexagons. OVRLand token is a non-fungible token based on the ERC-721 standard that also allows decentralised possession of digital assets such as OVRLands and OVRExperiences, that superimposed on reality through the eye of a mobile device or a smart glass, give life to augmented reality experiences. OVRLands are freely tradable among users in a decentralised fashion through the use of the marketplace OVROwner. This means that OVRLand owners can decide what kind of experience the user will experience once entered into the OVRLand. Therefore the community has complete control over OVRLands, and OVRExperiences. AR experiences can range from static 3D content and interactive highly complex and hyper-real scenes that make virtual content merge with the real world by engaging the user to a physical interaction with the surrounding world. So far, the system exploiting these experiences are mobile devices based on iOS and Android and Smart glasses such as Hololens, Magic Leap, and AR low-cost headsets based on the holokit project.
