![]() While Brave’s previous ad blocking mechanism was fast, it was not the optimal method for improving user experience.īy integrating the new and innovative algorithm, Brave can deliver optimized performance by simulating an API, on top of other key features. The new algorithm allows requests to be optimized to a level most browsers can only fathom. While this does not generate a single token for such rules, it hashes each positive option as a separate token. Hopefully Brave and the adblockers get to grips with it sooner rather than later. Maybe its a combination of Brave’ sorting things their end, along with adblockers, in response to Google or whoever playing around, I dont know. Brave’s new algorithm works kind of like tokenized hashes by limiting the rule evaluation to those that could be a potential match. All the filters in Brave’s default list have been useless for blocking adverts and cookie notices for me. The most vital improvement boils down to how quickly the upgrade eliminates any rules that are unlikely to match a request from search. Key factors that affect processing time include the number of rules that need to be checked before a request is accepted and the complexity of the rule being evaluated. However, the argument that popular ad-blockers could indeed be more efficient pointed out that Brave could also improve the process. The recent controversy surrounding Chromium extensions using WebRequest API to inspect and block what it considered to be undesired requests, did not meaningfully affect Brave due to the depth of the latter’s network stack. The team found that the browsing experience could be further optimized to enhance the ad blocker by roughly 69 times.Īs of today, this implementation has been successfully rolled out in the Dev and Nightly versions of Brave. Loading the average web page invokes 75 requests, which need to be checked against tens of thousands of rules to optimize the browsing experience.Įven though Brave already had a well-functioning ad blocking mechanism which was heavily optimized in C++, handling requests at above par speed required further upgrades to the browser. The result of this upgrade is an exponential increase in the efficacy of the shields using a new code base developed in Rust, as per a blog post, June 26, 2019. ![]() Brave Shields, one of the key components to a seamless browsing experience, which protects users’ privacy, was rebuilt with inspiration from uBlock Origin and Ghostery’s ad-blocker engines.
