India, as one ofthe countries with the largest population, has huge potential in its digitalcontent market. It is estimated that India’s online content consumers willreach 500 million within the next five years.Our principle is that All Contents Are Created Equal, so the foun-dation propose a protocol named Content Neutrality Network CNN Plat- and corresponding ERC20-compliant tokens [1, 2]for the content in-dustry based on the innovative blockchain technology. Our proposal is ap-plicable for all of the content communities who are willing to adopt the CNNPlat protocol.CNN Plat brings a revolution to India’s and global digital con-tent market. To address various issues of internet content communities,CNN Plat introduces several mechanisms/protocols related to contentcreation, distribution, circulation and revenue share. For example, CNNPlat combines personalized recommendation with the community votesto distribute the most relevant content to each user. CCM Content Circu-lation Mechanism is designed to stimulate seamless circulation of contentamong different communities. In addition, a neutral and efficient revenueshare mechanism is made feasible in the ecosystem of CNN Plat withCBRS Contribution Based Revenue Share mechanism. Under CBRS, userswho have seldom enjoyed the commercial earnings of content plat willparticipate in the ads revenue share for their contribution of attention.CNN Plat has ed a strategic partnership with NewsDog, In-dia’s No.1 content plat. NewsDog has more than 40 million users, andsupports 10 languages in India. As the first application on CNN Plat,NewsDog will fully utilize the CNN Plat’s protocol to build an open,neutral and efficient content community. NewsDog will invite all of its usersto hold CNN and enjoy the benefits of CNN protocol. The foundation be-lieves NewsDog will soon become one of the largest content communities onblockchain.The goal of CNN Plat is to grow to the most popular protocol forcontent communities globally. The foundation believes CNN Plat canpromote more efficient content distribution as well as motivate the commu-1CONTENTS 2nity members to create better content and engage more on the plat,which would in return bring better benefits to all participants in the ecosys-tem.Chapter 1Background1.1 Prospect and Problems in the Digital ContentIndustryThe development of Internet and mobile devices has provided a newprocess for ination distribution. Instead of receiving ination vianewspapers, magazines, and books, as was done in the past, people can nowaccess ination from websites, mobile apps, and other digital devices invarious s, including articles, pictures, videos, GIFs, and other s ofstreaming media.Statistics show that the market size of the global digital content industryreached 109.1 billion USD in 2016, and this figure increased significantly to224.8 billion USD in 2017. In the same year, China’s online news usersreached 579 million and the online content industry generated a revenue of382 billion RMB. Take Bytedance Inc. for example, its DAU reached over160 million in 2017, and its annual revenue reached 20 billion RMB.With over a 1.3 billion population, India is very similar to China whoseoverwhelming demand for digital content cannot be ignored. It is conserva-tively estimated that India’s online news users will reach 500 million withinthe next five years. The foundation believes that the content industry willhave a promising future in China, India, and other places all over the world.Despite the rapid growth in the content industry, certain issues cannotbe ignored Flood of low-quality content consuming user attention A con-siderable number of people deliberately add vulgar, violent, and sexualelements to make their articles eye-catching. Some even publish fakenews so that people will fall fo
