Basic Attention (BAT)
Basic Attention Token (BAT) is an open-source, decentralized ad exchange platform built on the Ethereum blockchain. The platform aims to revolutionize the digital advertising industry by tackling issues such as fraud, opacity, and inefficiency. BAT was introduced to the market through an initial coin offering (ICO) on May 31, 2017, successfully raising approximately $35 million USD in under 30 seconds. The primary goal of BAT is to improve the digital advertising landscape by ensuring transparency, fairness, and user privacy.
History of Basic Attention Token
The Basic Attention Token was created in 2016 by a team led by Brendan Eich, the creator of JavaScript and a co-founder of Mozilla. Alongside Eich, notable team members include Brian Bondy, lead developer and co-founder of Brave, and Scott Locklin, senior engineer and co-founder of Kerf Software. The team behind BAT also developed the Brave browser, which is central to the token's ecosystem.

How Basic Attention Token works
The role of BAT in digital advertising
Basic Attention Token operates by creating a new, efficient marketplace for digital advertising that benefits advertisers, publishers, and users. Advertisers pay BAT tokens to website publishers in exchange for user attention. The token is designed to accurately value and price user engagement within the platform.
Key components
The BAT ecosystem comprises several components, including attention measurement systems, analytics dashboards, and machine learning algorithms. These components work together to provide a seamless advertising experience that prioritizes user privacy and data security.
Integration with host applications
To integrate BAT into a host application, the platform utilizes BAT Ads. This system matches and displays ads to users based on data stored locally on their devices. By performing ad targeting entirely on-device, BAT eliminates the need for third-party tracking, thereby ensuring user privacy.
The Brave browser and user interaction
Privacy-focused browsing
The Brave browser is an open-source, privacy-centric browser designed to block trackers and malware. It employs blockchain technology to anonymously and securely track user attention, which is then translated into rewards for publishers. The browser's architecture ensures that all user data and tracking information remain on the user's device, maintaining anonymity and privacy.
Measuring user attention
In the BAT ecosystem, user attention refers to focused mental engagement with digital content, such as advertisements. The Brave browser logs this attention, allowing users to earn rewards while protecting their privacy. By keeping private data on the user's device, BAT provides a secure and anonymous browsing experience.
