Blocknet (sometimes referred to as Block) is a decentralized, platform-as-a-service protocol that connects the nodes of different blockchains. As you probably know, there are hundreds, if not thousands, of blockchains that currently exist, and this number is showing no signs of slowing down its growth anytime soon. Many of these chains, though, are unable to communicate and interact with each other, creating small groups of siloed ecosystems. And, the inability of these groups to work together is holding back the entire blockchain industry. To solve this problem, Blocknet is working to make blockchains interoperable, mobile, and modular. This enables different chains to provide microservices to each other in a peer-to-peer fashion at higher security, faster speeds, and more efficient scalability than today’s current options. Blocknet is aiming to be the “Internet of Blockchains” through inter-blockchain connective services. Simply put, Blocknet enables you to develop on one blockchain, Ethereum for example, but access the functionality of other chains, like NEO. The team is building the infrastructure using three core components that work together to provide three primary services for these inter-chain decentralized applications (dapps). The XBridge, a blockchain router, is the backbone of the Blocknet platform. It’s the first peer-to-peer protocol to connect nodes on different blockchains, allowing them to communicate with one another. Using the XBridge, you’ll not only be able to perform cross-chain atomic swaps, but you’ll also be able to transfer additional data and execute smart contracts across chains. Blocknet uses a Proof-of-Stake consensus algorithm with three types of nodes to maintain the network. Service nodes collect and distribute trade fees on the platform as well as prevent spamming and DDoS attacks. To run a service node, you need to hold at least 5,000 BLOCK and keep your node computer running at all times. The Blocknet team recommends that, if you plan to run a service node, you should also run multiple full node wallets of whichever coins you want to support. This maximizes the trading fees you receive. Staking nodes confirm network transactions. When running a staking node, you’ll receive 9-14% annual returns from block rewards as well as a portion of the trading fees. There’s no minimum BLOCK amount you need to keep in your wallet to receive these, but you need to keep the wallet running at all times. There’s limited information available on the Blocknet team. Dan Metcalf and Arlyn Culwick founded Blocknet in 2014 as a fork of PIVX. According to his LinkedIn page, Metcalf was a Bitcoin developer for 5 years as well as a Senior DevOps Engineer at Philips. Outside of Blocknet, Culwick is also the PR and Media Liaison for XCurrency. Blocknet launched the service nodes on their main net in September 2017, and on March 1st, 2018, the team will release the beta version of the DEX. The project has also partnered with the 0x protocol to add ERC20 token support on the platform. Blocknet is connecting the isolated blockchain systems that currently exist to create one, cohesive ecosystem. Through the platform’s XBridge, the team is building a blockchain Internet in which you can build dapps that utilize features from several different chains. Starting with a DEX, the project has a lot on its roadmap including a service delivery system for blockchains to provide and receive payment for providing functionality to other chains. This is a complex project, but Blocknet already has the partnerships in place (0x, Poloniex) to see it through to the end. Blocknet consists of the following coins: XCurrency, Stealth, SonicScrewdriver, Fibre, Librexcoin, APEXcoin, BitSwift, XCash, UtilityCoin
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.
