They can donate them back to publishers or use them on the platform. This transparent system keeps user data private while delivering fewer but more relevant ads. Publishers experience less fraud while increasing their percentage of rewards. And advertisers get better reporting and performance.
The first part of the solution, the Brave browser, is already operational. Brave is a fast, open source, privacy-focused browser that blocks ads and trackers, and contains a ledger system that anonymously measures user attention aggregate to accurately reward publishers. The next step is introducing BAT. ... "
