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.
VITE - A Next Generation High-performance Decentralized Application Platform DAG Ledger Transactions in Vite are grouped by accounts. That is, each transaction only changes the state of one single account. Send transactions are separated from receive transactions, thereby obviating the need to wait for a transfer to be complete before the initiation of another transaction. The hierarchical design of the consensus algorithm allows horizontal scalability in consensus groups. Asynchronous Architecture Vite splits transactions into transaction pairs according to a 'request-response' pattern. The writing and verification of transactions are asynchronously decoupled, thereby supporting ultra-high throughput. Inter-contract communications are based on an asynchronous messaging model. Reactive Contract Message-Driven With an event-driven architecture, every smart contract is viewed as an independent service. Contracts communicate via messages without sharing state. Solidity++ Solidity++’s syntax is compatible with most of that of Solidity. The new syntax supports asynchronous semantics, contract scheduling, and provides a series of standard libraries, such as string manipulation, floating-point operations, basic mathematical operations, containers, sorting, and so on. Integrated Decentralized Ecosystem End-to-end system for value transfer Vite itself is a decentralized exchange that supports digital asset issuance, cross-chain value transmission, and inter-token transactions based on the Loopring protocol. A quota-based resource allocation mechanism allows light users to pay zero fees and gas. Users can obtain computing resources in multiple ways. Vite also supports quota leasing. dApp Mini Programs The Vite client features an engine for creating HTML5-based decentralized mini programs. This engine simplifies the process of dApp development and deployment.
