BAT operates through the Brave browser, which is privacy-focused and blocks unwanted ads and trackers by default. When users opt into the Brave Rewards program, they start earning BAT for viewing privacy-respecting ads that are matched to their interests. The Brave browser anonymously monitors user attention through its machine learning algorithms, tracking the time spent on each ad and the engagement levels. This data is then used to distribute BAT tokens to both users and publishers. Users receive a portion of the ad revenue in BAT tokens as compensation for their attention and engagement. They can use these tokens to support their favorite content creators by tipping or contributing directly to websites and online platforms. Publishers, on the other hand, receive a share of the ad revenue based on the attention their content receives. This creates a mutually beneficial ecosystem where users are rewarded for their attention, advertisers can target relevant ads, and publishers can monetize their content. The transparency and efficiency of BAT are achieved through blockchain technology. By utilizing smart contracts on the Ethereum blockchain, BAT ensures secure and auditable transactions between advertisers, publishers, and users. The system aims to eliminate middlemen and unnecessary intermediaries, reducing fraud and increasing revenue distribution to the relevant parties. Additionally, user privacy is upheld as the Brave browser keeps personal data on the device rather than on centralized servers.
