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.
Feathercoin (FTC or ₣) is an open source cryptocurrency, published under the license of MIT / X11.1, based on the Litecoin protocol. On 16 April 2013 Feathercoin successfully forked from Litecoin by the creation of its genesis block. As a cryptocurrency, creation and transfer of coins is based on an open source cryptographic protocol (the blockchain) and is not managed by any central authority. The hashing algorithm chosen for Feathercoin was the Proof-of-Work NeoScrypt, which had premiered on Phoenixcoin. NeoScrypt is 25% more memory intense, which makes it less feasible to create ASICs for it. The main programmer is Peter Bushnell, at the time running the information technology for the Brasenose College of Oxford University. He explained his motivation for developing the coin in an interview with Vitalik Buterin. One month after launching Feathercoin, Peter Bushnell left his job as head of IT at the Brasenose College of Oxford University and lived off his Litecoin savings. Feathercoin was launched on 16th April 2013 and as developed by Peter Bushnell. It was forked from Litecoin, with the aim of making Feathercoin what Litecoin was supposed to be: a faster, more secure, and stable version of Bitcoin. The consensus mechanism is based on the Proof of Work (PoW) concept. The Feathercoin network runs on the NeoScrypt hashing algorithm, making it much easier and faster to mine. Feathercoin enjoyed rapid adoption by users soon after its launch, gaining immense popularity, and establishing itself as a worthy contender in a BTC/LTC dominated market. Feathercoin can be mined using either processors (CPUs) or graphics cards (GPUs). Due to the hashing algorithm of FTC, it cannot be mined with an ASIC card. Mining software is available for download at their official site. Wallets for FTC can be found over at their official website, including both desktop and mobile wallets.. While the paper money you are used to carrying around is (or can be) stored in a physical wallet, cryptocurrencies, like all digital currencies, have to be stored in a software-based digital wallet. Although you will find links to feathercoin wallets throughout the web, the only safe way to know that you're downloading the latest and correct version is by scrolling to the bottom of the coin's official home page and selecting the button for your particular operating system. Feathercoin wallets are available for Android, Linux, macOS and Windows platforms.
