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
