One of the biggest complaints I hear from people about BRAVE Browser and earning BAT is how at its core BAT earnings are centralized. Those who said that were not wrong in the slightest as the best and most secure way to preserve privacy while also allowing individuals to earn BAT was from a protocol called Privacy Pass. Privacy Pass did its job, preserving users' privacy while earning BAT, extremely well, and by doing so in a way created a new problem for the Brave Team as they had to create a decentralized protocol that would live up to the standards of Privacy Pass but not be centralized. Finally, after who knows much time spent tackling this issue the Brave Research team is finally ready to implement the solution.... Boomerang.
How is this done? Brave Researchers have created a novel protocol that applies multiple layers of privacy-preserving measures. This multiprong approach in particular leverages Zero-Knowledge proofs based on something called Bullproofs that utilize and leverage L1 blockchains and then laid on top of this is that they further leverage Black Block Accumulators. The Zero-Knowledge proofs deal with the BAT rewards themselves and mark them on an L1 blockchain. By using Zero-Knowledge proofs any sort of sensitive information is not released or released. Doubling up on privacy is where the Black Block Accumulators come into play as they securely store the user's interactions with the Brave Ads.
Below is a figure that Brave Released to display how the process works!
This novel approach to BAT rewards is a huge win for those who value decentralization and privacy. It is amazing that Brave realized that with the BAT rewards, there was an issue with how they were essentially centralized and really hard to track and understand. Now though with the implementation of Boomerang users and others can look and see the process in its entirety! Brave still has a ways to go most particularly with addressing the custodial account (Gemini or Uphold) that most people do not want to hassle with but as it currently stands regulators have really tied their hands and forced them and thus users to use these certain CEXs.
