U Network is a revolutionary protocol for publishing and valuing online content that helps online content platforms better align with the interests of their users. It does this by rewarding content creators more for their work, by letting users earn money for predicting popular content, by making it easier to discover high quality content, and by allowing all users to be part of content moderation and governance decisions. The first online content community powered by U Network will be U Community, a digital asset information community. U Network aims to build a prediction market of user-generated content. By constructing a robust pricing system for content, U Network incentivizes users to spot high-value content and share it with the network. U Community is layered on top of U Network. In U Community, there are four types of users: content creators, content explorers, community moderators, and regular users. By using a prediction market for content, U Community will sustainably generate high quality content, helping users interested in blockchain technology learn more about various digital assets. In return for their work, content creators, explorers, moderators will be rewarded with Sugar, the internal fuel of U Network, making it a positive-sum-game for all community users. U Community will be deployed on the U Network native blockchain with highaccessibility, high-performance, and low latency. U Network will construct a decentralized, user-generated content ecosystem driven by fairness and quality.
