Brave is an open source    web browser based on the Chromium web browser and its Blink engine, announced by the co-founder of the Mozilla Project, Brendan Eich. It aims to block website trackers and remove intrusive internet advertisements, replacing them with ads sold by Brendan Eich 's company. Payments made thru Brave are processed in Basic Attention Token , an ERC20 Token Standard .
The browser also strives to improve online privacy by sharing less data with advertising customers, instead targeting web ads through analysis of users' anonymized browsing history. Brave intends to keep 15% of ad revenue for itself, pay content publishers 55%, ad partners 15% and also give 15% to the browser users, who can in turn donate to bloggers and other providers of web content through micropayments.   As of 2016, it is currently in version 0.11.0, and is in beta testing for iOS, Android, Windows, OS X, and Linux. 
Brave is developed by Brave Software which was founded in May 28, 2015 by Brendan Eich and Brian Bondy.  Brave was first announced by co-founder Brendan Eich on January 20, 2016 with the stated goal of providing an alternative to the widely adopted system of providing free content to end users supported by advertising revenue that is employed by many content creators and publishers on the World Wide Web. 
Eich identifies the impending conflict between advertisers, who are incentivized to collect and store detailed and, oftentimes, highly personal information about individual web users in order to deliver more effective advertisements, and users, who are increasingly averse to the collection of their personal information, as a "primal threat" to the web itself.
