StatementFor over a decade we have witnessed explosive growth of the digital content industry led by a variety ofweb and mobile content platforms such as Reddit, Youtube and Spotify. It has become an indispensablepart of our modern daily life, with audio and video streaming constituting 70% of Internet data tra , the success and fairness of the industry is impeded by several long standing challenges facingcreators, consumers, advertisers, and distributors of digital content.

3 Content creators struggle to profit from their own is extremely di icult to mon-etize one s created content online. On many content platforms such as YouTube and Instagram,users create all the content, from which platforms profit enormously by selling , the vast majority of creators are rarely compensated for their indispensable contribu-tions to these digital platforms. In addition, when creators do get paid for their content, layers ofintermediaries siphon o a majority share. Creators are in a weak position and lack bargainingpower to negotiate equitable monetization and payout terms.

4 It is not surprising platforms takemost of the revenue and creators only collect a small piece of the pie. For instance, when a songis streamed, only about 15% of the sales income goes to its creators, the bulk goes to streamingservice providers and record label owners. Content consumers receive no compensation for their engage ina wide variety of value-creating activities vital to content platforms, but are never : users spend valuable time interacting with platform content ( , liking,voting, flagging and commenting), filtering low quality from high quality content and receive nopayments for their participatory work.

5 They are commercially exploited by powerful platforms( , YouTube) at the expense of users unknowingly providing free : sharingwithin or outside a content platform ( , sharing a YouTube video with followers on YouTube orFacebook) brings more visibility to content and attracts more tra ic to the :the Internet is flooded with all types of digital content with greatly varying qualities. Therefore,content is no longer scarce, per se, but a user s attention is. A user spending limited attention oncontent, including advertisements, is valuable. Aggressive competition between content key user information and contentis locked in their proprietary data silos, it s nearly impossible for the content platforms to buildmutual trust, which o en leads to fierce competition in the digital content industry.

6 It is notuncommon that we see big content platforms bid for copyrights of popular content with insanelyhigh prices, driving up the cost of the bid winner and at the same time, leaving the small andmedium-sized platforms no choice but to turn to low quality or pirated content. And usuallythese surging cost will be transferred to end-users through longer ad times or higher , eventually degrading the user Blockchain-based EcosystemOur solution to the problems mentioned above is the ContentBox Platform, which aims to build ablockchain-based ecosystem for the digital content industry of tomorrow.
