Substratum (SUB) is an open-source foundation for the decentralized web that is designed to provide unrestricted access to content and sharing of information for users globally. The platform aims to develop an equal, free, and fair future of the internet by combining technological building blocks with innovation and integrating proven technological structures. Subsequently, the Substratum Network intends to combine innovative technology from the digital currency and community hosting platform.

According to the whitepaper, the Substratum Network is a worldwide collection of nodes that securely provides content without using a virtual private network (VPN). (A VPN is a private network that provides online privacy and anonymity to the protocol by forming a secret network from a public internet link.) The Substratum Network aims to solve the problems associated with the modern internet. In addition, Substratum runs on substrate andatoms staking coins equivalent to traditional currency.

SUB is an ERC-20 token based on the Ethereum blockchain. The token is the fuel that operates the Substratum Network. The Substratum platform users can earn SUB from routing and use SUB tokens for consuming content. Cryptocurrency smart order routing is the method of finding the available price across numerous exchanges to optimize the outcome of trading any pairs. Moreover, users can receive cryptocurrency rewards for running a Substratum Node and serving content for building a better and more open-source internet on the SUB platform. As the technical whitepaper suggests, Substratum Node is the foundation of the Substratum Network to mask and unmask CORES packages for personal information.

Abram Cookson is the founder and the chief executive officer (CEO) of the Substratum platform. Steve Swing is a chief technical officer (CTO), and Christian Pope serves as chief marketing officer (CMO) for the Substratum Network. The team decided to issue a total supply of 472,000,000 SUB tokens.

On August 14, 2017, the platform started the SUB Initial Coin Offering (ICO) until September 14, 2017. During the ICO sale, the Substratum platform issued 226,000,000 SUB tokens.
