What is Basic Attention Token (BAT)?

Deep Dive

1. Purpose & Value Proposition

BAT was created to reform the inefficient and privacy-invasive traditional digital advertising model. It introduces a user-centric "attention economy" where value flows directly between advertisers, content creators, and users. Instead of data being harvested by intermediaries, users who opt-in see privacy-respecting ads and earn BAT tokens for their attention. This model aims to provide better returns for advertisers through reduced fraud, fairer compensation for creators, and tangible rewards for users, all while preserving privacy.

2. Ecosystem Fundamentals

The token is the lifeblood of the Brave ecosystem. Users earn BAT through the Brave Rewards program by viewing ads. They can then use these tokens to tip or support verified websites and content creators directly, creating a circular economy. Advertisers purchase ad campaigns using BAT, which funds the user rewards pool. This entire process is facilitated by Brave's built-in wallet, creating a seamless experience that prioritizes user consent and transparency over traditional tracking.

3. Tokenomics & Architecture

BAT is a standard ERC-20 token on the Ethereum blockchain, ensuring interoperability with the broader crypto ecosystem. Its total supply is fixed at 1.5 billion tokens, with over 99% already in circulation, creating predictable scarcity. The token has no inflationary mechanism; its utility and value are driven by organic demand from the growing Brave user base—which reported over 128 million monthly active users as of September 2026—and its use as the required medium of exchange for advertising within the platform.

Conclusion

Fundamentally, BAT is a pioneering attempt to realign the incentives of the web by using blockchain technology to tokenize and reward attention in a private, efficient manner. As Brave's ecosystem expands into search, AI, and payments, how will the definition of "attention" evolve, and what new utilities might BAT encompass?
