nOS (pron. "en oh es" or "noss") is a full-stack solution for decentralized application development, deployment, discovery, and interaction. It describes itself as a Virtual Operating System due to the distributed services it aims to offer for both developers and end-users.

The project's private concept paper was authored January 2018 by nOS founder and CEO Dean van Dugteren. Dean publicly announced and presented nOS for the first time on April 14th 2018 at the NEO Amsterdam event.

The Token Generation Event has concluded in November 2018.

Feature Summaries

Transparent Back-ends

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.

Protocol and Name Service

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.

dApp Gateway and Decentralized Authority

The dApp Gateway is a user-friendly dApp discovery platform (“App Store”) where rankings are decided in a completely decentralized manner via Decentralized Authority.

Automatic Token Conversion

nOS eliminates the need for end-users to 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 into the required amount of application tokens that are needed to make specific transactions or invocations.
