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.
MATRIX AI Network (MAN) is a global open-source, public, intelligent blockchain-based distributed computing platform and operating system that combines artificial intelligence (AI) and blockchain. MATRIX was created to make blockchains faster, more flexible, more secure, and more intelligent. Besides boasting an impressive 50.000 transactions per second, there are a couple of features which makes Matrix AI Network stand out from its competitors. Matrix adopts a Hybrid PoS + PoW consensus mechanism instead of the traditional Hash computations. The mechanism makes use of value-added computation through the use of the Markov Chain Monte Carlo (MCMC) computations. This computation set is to be used as the Proof-of-Work protocol. This allows the mining process to not only generate MAN tokens but to also be used to power real-world applications. Currently being used in collaboration with Beijing cancer Research hospital to improve speed and accuracy of a cancer diagnosis. While the project seems ambitious with the integration of a working AI in so many areas, the AI-part is already done. Matrix now only has to deliver a working blockchain solution. MATRIX will be launching several community activities after its testnet launch, including a Bug Bounty Program and a Dapp competition, as well as introducing the MATRIX Blockchain Browser and Online Wallet Prototype. Details and instructions will be shared over the coming weeks. Full manner is set to launch December 2018. The MATRIX mining machine is set to launch for sale end of the year 2018.
