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.
MKR is a cryptocurrency depicted as a smart contract platform and works alongside the Dai coin and aims to act as a hedge currency that provides traders with a stable alternative to the majority of coins currently available on the market. Maker offers a transparent stablecoin system that is fully inspectable on the Ethereum blockchain. Founded almost three years ago, MakerDao is lead by Rune Christensen, its CEO and founder. Maker’s MKR coin is a recent entrant to the market and is not a well known project. However, after today it will be known by many more people after blowing up 40% and it is one of the coins to rise to prominence during the recent peaks and troughs. After being developed by the MakerDAO team, Maker Dai officially went live on December 18th, 2017. Dai is a price stable coin that is suitable for payments, savings, or collateral and provides cryptocurrency traders with increased options concerning opening and closing positions. Dai lives completely on the blockchain chain with its stability unmediated by the legal system or trusted counterparties and helps facilitate trading while staying entirely in the world of cryptocurrencies. The concept of a stablecoin is fairly straight forward – it’s a token that has its price or value pegged to a particular fiat currency. A stablecoin is a token (like Bitcoin and Ethereum) that exists on a blockchain, but unlike Bitcoin or Ethereum, Dai has no volatility. MKR is an ERC-20 token on the Ethereum blockchain and can not be mined. It’s instead created/destroyed in response to DAI price fluctuations in order to keep it hovering around $1 USD. MKR is used to pay transaction fees on the Maker system, and it collateralizes the system. Holding MKR comes with voting rights within Maker’s continuous approval voting system. Bad governance devalues MKR tokens, so MKR holders are incentivized to vote for the good of the entire system. It’s a fully decentralized and democratic structure, then, which is an underutilized USP of blockchain tech. Value volatility is a relative concept among both cryptos and fiat currencies. The US dollar, for example, was worth 110.748 yen on July 9, 2018. On July 4, 2011, $1 was worth 80.64 yen, and on March 18, 1985, $1 was worth 255.65 yen. These are major differences in exchange rates, and inflation within each country makes each currency worth different values even when compared to themselves. One USD in 1913 is worth the equivalent of $25.41 today, and even $1 in 1993 is worth the equivalent of $1.74 today. Stablecoins don’t negate these basic economic principles of value. Instead, both Tether and Dai have values pegged to the U.S. dollar. This is done to stabilize the price.
