Basic Attention Token (BAT) is a digital asset designed to improve online advertising efficiency. It operates on the Ethereum blockchain and is integrated into the Brave browser, which blocks unwanted ads and trackers.

Users of the Brave browser can earn BAT by opting into personalized ads. When they view these ads, they are rewarded with BAT tokens. This system benefits advertisers by providing them with a more engaged audience and users by compensating them for their attention. At the same time, publishers can receive BAT as a form of payment for their content, creating a more equitable revenue model.

The aim is to create a better balance between user privacy, advertiser needs, and publisher compensation. Overall, BAT seeks to create a more sustainable advertising ecosystem by directly connecting users, advertisers, and content creators in a way that respects privacy and rewards participation.
