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.
Nebula AI is a decentralized blockchain integrated with Artificial Intelligence and sharing economies. With the Nebula blockchain, developers can deploy their Artificial Intelligence applications easily on a blockchain platform. The integrated API/SDK and payment services allow the developers to earn revenue based on the AI smart contract. Nebula AI also allows the GPU miners to contribute their GPU hash power to AI computing power which allow for a variety of AI applications. This invention allows Nebula AI to compete with the pricing of Amazon and Google cloud computing services. The blockchain technology provides a digital trust mechanism for human beings which enhances the efficiency of value exchange and reduces costs, the genuinely credible and efficient Internet of Value is approaching. In recent years, many breakthroughs have been made in the field of artificial intelligence, and artificial intelligence has now penetrated every corner of human society and will become an essential cornerstone of change in human society. Nebula AI is committed to building a decentralized artificial intelligence computing blockchain (NBAI) that reduces the energy costs of traditional Proof of Work by converting GPU mining machines into AI computing services.The AI transactions recorded on NBAI will be irreversible. The distributed computing network also ensures high concurrency and low latency computing power. The conversion of GPU mining machines makes it possible to provide more cost-effective artificial intelligence services. Nebula AI will cooperate with large-scale third-party Internet data centers to provide adequate computing power for AI computing. Nebula AI has established an artificial intelligence training centre in Canada. System-based quantitative finance, image identification and other blockchain applications are also in development. The well-developed NBAI ecosystem integrates the top-level applications such as DAI App, scientific research and application, university education, and the bottom-level of NBAI blockchain, Artificial Intelligence Mining Machine and Artificial Intelligence Data Center. The innovative economic model of NBAI ecosystem is the realization of a complete set of value-added economic systems.
