Theta is a decentralized video delivery network, powered by users and an innovative new blockchain. Theta is an open source protocol purpose-built to power the decentralized streaming network and will allow for vertical decentralized apps (DApps) to be built on top of the platform to enable esports, music, TV/movies, education, enterprise conferencing, peer-to-peer streaming, and more. SLIVER.tv’s DApp will be the first application built on the Theta network leveraging its existing user base of millions of esports viewers. DSN and the Theta protocol solve various challenges the video streaming industry faces today. First, Theta tokens are used as an incentive to encourage individual users to share their redundant memory and bandwidth resources as caching nodes for video streams. This improves the quality of stream delivery and solves the “last-mile” delivery problem, the main bottleneck for traditional stream delivery pipelines, especially for high resolution high bitrate 360° virtual reality (VR) streams. Second, with sufficient amount of caching nodes, the majority of viewers will pull streams from peering caching nodes. This significantly reduces content delivery network (CDN) bandwidth costs, which is a major concern for video streaming sites. Lastly, the Theta network greatly improves the streaming market efficiency by streamlining the video delivery process. For example, advertisers can target end viewers at a lower cost and reward influencers more transparently.The Theta blockchain introduces three novel concepts: Reputation Dependent Mining: In the Theta protocol, the caching nodes play the role of miners in the blockchain. The block reward is not a constant, but depends on the reputation score of the caching node that mined the block. To obtain more mining rewards, miners not only spend computation power to mine blocks, but also relay video streams to downstream viewers to increase their reputation scores. Global Reputation Consensus: We propose a mechanism for the Theta network to reach the global consensus on the reputation scores for each caching node. Proof-of-Engagement: We introduce a novel Proof-of-Engagement scheme to prove that viewers legitimately consume the video streams, providing better transparency to advertisers and a basis for viewers to earn Theta tokens for engaging with the content.
Steem is a cryptocurrency that rewards users for community building by posting and upvoting valuable content for others. Steem was inspired from the success of Reddit where the community helped enrich the shareholders. Steem aims to help distribute the rewards to the community members who help create the community in the first place. Steem aims to provide various services to its members such as a source of curated news, Q&A, job boards etc. The founders of Steem came from BitShares with Dan Larimer involved as well. Steem’s main platform, called Steemit, is a social media network built on top of the Steem blockchain. Steemit is similar to popular content-driven social networks like Reddit and Medium, but it rewards users with cryptocurrency for their participation. Fundamentally, the more value a particular piece of content provides to a greater number of people, the more the individuals responsible for creating and curating that content can earn. Users cast votes, creating a hierarchy of content. The more upvotes a post gets, the more it will earn. The platform also allows for downvotes, giving participants more flexibility when it comes to rating content. Steemit is meritocratic, meaning users that hold more currency can cast votes with greater influence. The Steemit community even has another service to offer to its customers. D.tube, which is considered to be very similar to YouTube, is Blockchain based and the users can realize the difference between the traditional video publishing websites and D.tube, as the amount of money earned is also displayed beside the post apart from likes shares and comments. The Steemit community is accused of posting plagiarize contents on their publishing website. The irony seems to be reaching highest levels when the original content doesn’t receive much appreciation and income than the copied versions of it.'
