The new Brave browser automatically blocks ads and trackers, making it faster and safer than your current browser. Soon, micropayments and better ads will give users and publishers a better deal.

We know and respect that content on the Internet is largely advertiser supported, so our goal is not to remove advertising, but to put you back in control. Our architecture to do just that is – no surprise – an inversion of the traditional browser advertisement model. The traditional model treats the browser as a "silent partner". You are tracked by multiple third parties as you browse across different sites. Those parties build sophisticated (yet annoyingly incomplete) profiles in private clouds, and then some party (often distinct from the tracker) serves ads based on those profiles.

Our model is different: we call it the anti-cloud. We're not against cloud computing per se (of course!). However, we are very concerned about what and how much of our users’ data goes into the cloud and what the cloud does with that information. So, in Brave's anti-cloud model, all of your detailed information is kept only in the browser. Full stop, end of discussion. Our roadmap includes encrypting and backing up this information across your devices, but our servers will not see your data in the clear. (...)

Today we are discussing the Brave Ledger, a Bitcoin-based micropayments system for users and publishers.
