Tracking is the worst part of ad-tech. Ads can be annoying or entertaining, marketers will keep making them. Brave's opt-in ads use no tracking, match ads locally based on data generated in any browser, kept in cleartext only on your device. Matching is against a catalog that's the same for all users in a large population who speak the same language. Confirmation of views/clicks uses a protocol based on privacy pass (Chaum blind signature cryptography).

The problem with tracking ad-tech is the sum of the massive conflicts of interest it creates: advertiser vs. user vs. intermediary vs. publisher. Brave aligns with users first by paying them 70% of the user ad revenue, with publishers who partner with us who get 70% while the user gets 15% (so 1/ we pay 70% to owner of ad slot; 2/ we always pay user >= what we take). We then help users support creators, anonymously and easily, not only website publishers but especially youtubers and others. See https://batgrowth.com/ and sign up -- we pay $5USD in BAT per new 30+ day user you refer. https://brave.com/refer

By aligning with users first, we are confident great creators will do well as their users support them with automated contributions, pinned subscriptions, and tips. Who loses? The ad-tech intermediaries we block. You already give your data to your browser. Don't let it be a blind slave of the middlemen. They are not needed.
