Brave Software has developed a cryptocurrency enabled web browser that is designed to change the ad-based revenue models of the internet. The Brave browser is powered by an Ethereum-based token, and revolves around a blockchain-based digital advertising platform. It has the potential to change the existing online media dynamic and better meet the needs of internet users, publishers and advertisers. Users benefit from a faster web experience, publishers can increase their revenue with less cluttered ads, and advertisers will benefit from more transparency and more effective ads. At the core of Brave's platform is the Basic Attention Token (BAT), that enables micropayments between users and publishers. They hope to establish a new revenue model for the web that isn't based on intrusive ads, but on user attention.
