Basic Attention Token (BAT) is a revolutionary digital advertising platform that aims to address the inherent flaws in the existing online advertising landscape. Established by Brendan Eich, the co-founder of Mozilla and creator of JavaScript, BAT is integrated with the Brave browser, which is designed to be fast, privacy-oriented, and to block intrusive ads and trackers. BAT is an ERC20 token on the Ethereum blockchain that enables advertisers to pay for user attention and rewards users for viewing ads, thereby creating a more efficient and equitable marketplace. Users'engagement with ads is anonymously monitored, and publishers are rewarded accordingly, all without compromising on privacy—a novel approach that seeks to bring fairness back to the digital advertising space.
