I'm Sampson, from the Brave team. The Web Discovery Project is a clever approach. For Brave to compete with Google, and offer a truly novel index of the Web, a novel approach must be taken. The WDP is an opt-in, privacy-preserving approach which gives Brave a fighting chance against the Search incumbants. Due to our preference of "Can't be evil" over "Don't be evil," the WDP is not only designed with privacy and anonymity as a prerequisite, but it is also open-source for public scrutiny and evaluation:
