Built upon the Ethereum blockchain, BAT (Basic Attention Token) is the native token of the Brave web browser.
The objective behind the creation of BAT is to improve digital advertising in a way that would be advantageous to users, publishers, and advertisers at the same time. BAT is intended to be used as currency on the Brave web browser; it can be used to acquire multiple different advertising services and can be exchanged between users, publishers, and advertisers. BAT was developed, keeping one basic concept in mind: user attention.
BAT would be used to track the users’ time and attention on various websites while using the Brave web browser. Users would be able to choose what kind of advertisements they want to see, so the ads can be tailored to their interests without them having to give up any sort of private information. Publishers would be able to come across new sources of revenue, and advertisers would get to target specific, interested users based on their content preferences. Thus, BAT aims to efficiently distribute advertising money between users, publishers, and advertisers.
As of 2020, the BAT project is still in the development stage.
