The project introduces Theta blockchain to address the challenges facing the video streaming industry today. First, the project uses Theta tokens as a reward mechanism to encourage users to share idle computer memory and bandwidth resources and become a cache node for video streaming media. This approach can somehow address the main bottleneck of traditional streaming media distribution networks (CDNs), the so-called "last mile" distribution problem. Secondly, when the number of cache nodes is sufficient, most users can capture streaming media from peer-to-peer cache nodes, thereby reducing the bandwidth cost of the content distribution network and reducing the operating costs of major video streaming websites. Finally, through decentralization, Theta tokens can increase the efficiency of the streaming media market. For example, advertisers can target end-users at a lower cost and more transparently reward network red anchors and video content providers.
