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.
OneLedger enables you to focus building your business application through OneLedger modularization tools, which will communicate with OneLedger protocol using its API gateway. This mechanism will make your business application interact with different public and private blockchains synchronously through corresponding side chains implemented in OneLedger platform. OneLedger defines a three-layer consensus protocol to enable more effective integration of different blockchain applications. Business logic can be implemented by the first layer – a configurable role-based consensus protocol leveraging hierarchical grouping similar to the structure of Merkle Tree. The side chain consensus protocol can move consensus traffic from the main chain with public consensus to the side chain with high performance and efficiency. OneLedger block structure enables the synchronization and reference between the three-layer consensus. The company works as a cross-ledger blockchain platform for people to make exchanges through business methodology. Not only that, but it’s also developed using the enterprise blockchain technology solutions that are running across the globe like something the world has never seen. One Ledger also operates as a powerful consensus engine that will help people with governance, so they can rest assured their transactions are being completed legitimately. The SDK on the platform is also highly customizable. And the platform, in general, is highly scalable and reliable. The architecture of the One Leger is built around the focal point of building your business software through the One Ledger modularization tools. They are set up to communicate with One Leger’s advanced protocol via the unique API gateway used by the platform developers. The new method of operation is designed to make your business application work together with different private and public blockchains in synchronicity by way of side chains that work together and are implemented via the One Ledger platform. The platform is designed to help people in a wide range of different business models. People in finance, agriculture, transportation, manufacturing and just about anything else will benefit highly from the One Ledger protocol. It works with Bitcoin, Ethereum, HyperLedger and several other platforms.
