Substratum is an open source network that ensures the dissemination of information remains free and democratic. Substratum seeks to open up the website to those who may have restricted internet access due to their country’s political climate. Substratum does so without a VPN or Thor address. Instead, anyone can become a Substratum host, which allows Substratum hosted content to be accessible regardless of censorship or restriction.
The Substratum node relies on users to host web content, but in exchange for hosting, users are paid with SUB tokens. The cost of hosting, however, is determined per click so the more popular a site is, the more expensive it is to host on Substratum.
