nOS is a virtual operating system with the ability to access a new, decentralized internet. On this new internet, applications can be open and transparent. User data is safe, and only goes where the user wants it to go. Because applications can choose to make their back-ends fully open-source, this new layer of the internet is defined as Open Internet.nOS solves key issues surrounding dApp discovery, interaction, and development, allowing for true adoption of decentralized applications and blockchain technology.1.On nOS, websites and apps host their content in a completely open and decentralized manner using Smart Contracts, giving users complete insight about what happens with their data. Unlike server-side backend code, smart contracts can be open, and users can see what happens with their data and actions before it happens. This allows for total transparency between users and applications. 2.To access the Open Internet, nOS introduces its own desktop and mobile client which features a new type of web browser. This web browser utilizes a domain name service built by nOS as a smart contract on top of the NEO Blockchain, and can be used to host and access applications and websites on the nOS protocol. 3.When using multiple dApps, users never have to work with different tokens. End-users only use blockchain platforms� primary crypto-currency or token (i.e. GAS for NEO), and nOS automatically converts it to the proper amount of application tokens required for a specific transaction or invocation.4.nOS introduces a dApp Discovery Gateway, where applications are listed and rated in a completely decentralized manner with Decentralized Authority.
