The project introduces the Theta blockchain to address the challenges faced by today's video streaming industry. First, it uses Theta tokens as a reward mechanism to incentivize users to share their idle computer memory and bandwidth resources, becoming cache nodes for video streaming. This method can, to some extent, solve the main bottleneck of traditional content delivery networks (CDNs), namely the so-called "last mile" distribution problem. Second, when there are sufficient cache nodes, most users can retrieve streams from peer cache nodes, thereby reducing the bandwidth costs of content delivery networks and alleviating the operational costs of major video streaming sites. Finally, through decentralization, Theta tokens can improve the efficiency of the streaming market. For example, advertisers can target end-users at a lower cost and more transparently reward influencers and video content providers.
