In return for their attention, users are rewarded with cryptocurrency.\nBrave uses FL to alleviate the need for storing and collecting user data while still delivering well-targeted ads. They show that they can achieve a hit ratio at 10 (HR@10) of up to 70% while achieving almost perfect privacy preservation.\nGoogle began rolling Federated Learning of Cohorts (FLoC) on Chrome in Q2 2021. To avoid providing individual user data to third-party advertisers, FLoC groups together users into cohorts with similar browsing histories without ever centralizing these histories. Google clients only access data about cohorts, not individual users.\nGoogle claims that advertisers “can expect to see at least 95% of the conversions per dollar spent when compared to cookie-based advertising.”",
