Openverse Whitepaper

Abstract Today, XR app developers are dependent on centralized, permissioned distribution channels for their income. These channels take 30% of the revenues in exchange for the placement of a creator's content on their digital shelf. These platforms are not necessarily the most benevolent governments to build a community in, especially since they have been known to block certain apps from working properly, preventing developer from building valuable features, and in the worst case cannibalizing an app altogether. Our goal is to provide developers with a way to reduce their dependence on centralized channels. We will accomplish this by building a protocol which enables the tokenization of digital space and an auditable record of interactions with the digital spaces. Through the use of scalable web3 protocols, we will enable a more transparent financial settlement layer for the exchange of value between advertisers and the creators who are offering spatial liquidity. Gone will be the days when payment processors take a cut of the transaction. Through the use of a profit-sharing token, all stakeholders of the network, including investors and protocol developers, will be able to benefit from the growth of the network. Introduction Augmented and virtual reality provides a new substrate for the creation of spatial experiences that have some form of spatial scarcity. Why XR?
