nOS is a virtual operating system that introduces a new, decentralized internet. On this new internet user data is safe, and it only goes where the user wants it to go. nOS solves key issues surrounding dApp development, deployment, discovery, and interaction, allowing for true adoption of decentralized applications and blockchain technology. Because applications can choose to make their back-ends fully open-source and transparent, this new implementation of the World Wide Web is defined as the Open Internet. On nOS, applications and websites can be deployed in a completely open and decentralized manner by integrating smart contracts, client-side code, and public-key cryptography. Unlike server-side backend code, smart contracts can be open for all to read, allowing users to review how their data will be transmitted before any final commitments to action. Client-side code and other frontend materials can be distributed via nOS Filesystem, a decentralized file sharing protocol that allows for secure and transparent distribution of static files. By serving both backend logic and frontend material in an open-source, decentralized manner, true transparency between user and application can be achieved. dApps that are deployed to nOS can be accessed through nOS Client, a software solution for desktop and mobile that (among other features) introduces nOS Browser. nOS Browser functions as a web browser, with the added benefit that it integrates with the nOS Protocol, a blockchain-powered web protocol that facilitates secure and open accessibility of nOS dApps. The nOS Protocol resolves domain names that exist on nOS Name Service, a blockchain-powered decentralized implementation of a Domain Name Service, and allows for dApps to register domain names which are discoverable on nOS (e.g. mydapp.neo or my-dapp.eth). The dApp Gateway is a user-friendly dApp discovery platform (or “App Store”) where rankings are decided in a completely decentralized manner via Decentralized Authority. In order to achieve the features such as the ones described above, nOS is powered by the nOS Utility Token. The nOS Utility Token employs various staking and reward utilities which are intended for developers who wish to deploy and maintain dApps on nOS, and for end-users who wish to practice governance by Decentralized Authority. nOS eliminates the need for end-users to manually exchange crypto-currencies in order to make use of various dApps. By integrating crypto-currency exchange APIs, nOS Client automatically converts primary blockchain platform currencies (e.g. NEO/GAS for NEO, ETH for Ethereum) into the required amount of application tokens that are needed to make specific transactions or invocations.
ICON is a blockchain technology and network framework designed to allow independent blockchains to interact with each other. ICON is supported through a cryptocurrency token, called ICX. ICON is a South Korean-based company that developed a blockchain technology and accompanying cryptocurrency token called ICX. The company bills itself as an interconnected blockchain network, allowing participants in a decentralized system to “converge” at a central point. This is done by connecting a community to other communities through ICON Republic and Citizen Nodes. While blockchains are most commonly associated with cryptocurrencies, enthusiasts point out other areas where the technology can be applied. Any exchange of information can technically be added to a blockchain, though adding some types may not be cost-effective. Transactions involving securities, currencies, business contracts, deeds and loans, intellectual property, and personal identification could be “tokenized. ICON’s blockchain is more like the Plasma or Ontology blockchain in that its purpose is to act as an intermediary between other blockchains and networks. This interconnectability makes the ICON project worth keeping an eye on over the next decade. ICON sports its very own decentralized exchange. This DEX sets currency reserves for each blockchain community so that ICON communities can exchange value in real time through the ICON Republic. In this way, DEX complements C-Rep portals by establishing another gateway for ICON Communities to connect to the ICON Republic.
