Cardstack is an open-source framework and consensus protocol that makes blockchains usable and scalable for the mass market, creating a decentralized software ecosystem that can challenge today’s digital superpowers. Cardstack Token (CARD) is a utility token allowing end- users and businesses to use applications that interact with multiple blockchains, decentralized protocols, app-coin-backed dApps, and cloud- based services while paying a single on-chain transaction fee. The main value proposition of the Cardstack ICO is to breakdown the user experience of disparate software, cloud and blockchain silos which now exist on various levels of the digital world, allowing both developers and users to engage in customizable workflows. To overcome these disparate app silos, Cardstack offers a new UI, deployed via the web or as a peer-to-peer app, which turns each service created by open-source developers into a “card”. Each card comprises a visual embodiment of key information, whereby users can then connect related cards for any type of workflow or utility they desire. These cards are the point of interaction between local services, cloud-based services and blockchain services all on one interface called Cardstack Hub. Underlying the Cardstack ecosystem is the Cardstack Token (CARD), an Ethereum-based ERC20 token. The Cardstack Team comprises many open source contributors. Check out the full list of contributors here. Heading the development of Cardstack is Christopher Tse. Christopher holds a BSc in Computer Science from Columbia University and is the Co-Founder of Monegraph and dotBlockchain Media. He has also served as Senior Director of Innovation at Businessweek. Ed Faulkner is the Lead Developer at Cardstack. He holds a Master of Engineering in Electrical Engineering and Computer Science from MIT. He has founded three of his own tech ventures of which all are currently operational. Hassan Abdel-Rahman is the Lead Blockchain Developer for Cardstack. He holds a BSc in Computer Science and Mathematics from Colorado School of Mines. Previous roles include over 2 years as Senior Software Designer at Monegraph and Principal Engineer at McGraw-Hill Education. One of the most important features Cardstack will deploy is an entry channel payment system that does not require users to purchase cryptocurrency from an exchange. Users can simply pay with fiat, such as a credit card, to purchase CARD tokens directly on the platform, bypassing the need for any prior familiarity with crypto. Once users purchase CARD tokens, they are stored on a native wallet accessible from the Cardstack Hub. CARD tokens held in the native wallet are then used to purchase SSCs for every app and service they users with to access. To make any project appealing to the mass consumer market, this type of simplified entry into the cryptospace is a necessity. Cardstack have made some progress on the development front. The code for over 30 initial modules on the Cardstack platform has been made available via their Github. Also, the Solidity code for the Scalable Payment Pool has already been open-sourced. The Scalability Payment Pool is one of the core back-end mechanisms of the platform that issues rewards to developers for their work. Cardstack aims to create an economically-sustainable software ecosystem that avoids the problems of today’s centralized platforms. It’s an “experience layer” for the decentralized internet of the future, allowing users to combine services across cloud apps and decentralized apps. The ecosystem revolves around the use of Cardstack tokens, or CARD.
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.
