REOS is a blockchain-based ecosystem for user generated content (UGC) that empowers content creators and consumers. The platform enables content creators to monetize their UGC, such as short videos, in a variety of ways, without a middleman, while making sure that the content is validated by the REOS community. All digital content contributed by content creators are also registered on the REOSchainTM, the main blockchain for the REOS community, to ensure accurate attribution of ownership of the digital assets. Content creators can be securely paid by various stakeholders, bypassing any intermediaries, by using REOS, a utility crypto-token issued by REOS Foundation. The value of the content will be determinedby the REOS community rather than by any central authority, thus honoring the belief that “Truth is Value.” With the worldwide adoption of fast, affordable mobile Internet, UGC from wikis to photos and videos has exploded over the past decade. Videos are expected to account for 75% of the mobile data consumption by 2020 . Snapchat alone is estimated to have had 14 billion 1 daily views of its short, ephemeral videos in October, 2017 . Led by short video apps like 2 Kwai and Toutiao, China has seen tremendous growth in short video consumption, with 152 million daily average users (DAUs) of short video apps in 2016 and 244 million in 2017, at a staggering YoY growth rate of 60% . Other content types are also flourishing. Wikipedia has more than 2.36 million contributors worldwide , whereas Yelp boasts over 100 million unique 4 mobile visitors in Q3 2017 and more than 100 million reviews written as of March 2016 . REOS overcomes these shortcomings by using blockchain technology. We believe that the fundamental value of UGC is dependent upon reflecting the truth of content validity, ownership and rights-of-usage. Therefore, we try to create a community of content creators, promoters and consumers where members are incentivized to dig out the truth. Inspired by Reddit’s Up-vote/Down-vote mechanism, we are developing a truth ratings system on top of the REOSchainTM, along with the issuance of REOS tokens. REOS intends to disrupt existing centralized, advertising-driven social media by effectively leveraging blockchain technology to give power and control back to content creators and consumers while ensuring validation of UGC.
