Loki combines a private transaction network based on Monero with economically incentivised service nodes to create a trustless quorum based networking protocol. This protocol allows anyone to route small packets of data in an anonymous and decentralised way. The front end applications that use this packet routing system are private-by-design, and are known as Service Node Apps “SNApps”; the first of which is the Loki Messenger - a decentralised, anonymous and private messaging service.

BitTube as a company offers several products that make up an ecosystem. At the heart of this ecosystem is a blockchain-based technology called AirTime, an ad-free monetisation solution that pays a cryptocurrency (TUBE) based on watch time of any type of content. Payouts are taken from a slowly decreasing block reward, calculated based on a user’s AirTime compared to the grand total AirTime per each block. More information can be found at https://bittube.app
