Substratum - 

The future of the decentralized web, Substratum offers the ability to connect to a vpn-like network hosted entirely by coin members. Members can set up and host nodes similar to the tor network, and be rewarded for hosting a node with $SUB. When you connect to the network, your ISP will only be able to see you are connected to the Substratum network, and you will be able to connect to any website you like.
