The true currency of the Internet is not Bitcoin or Ethereum, but attention. Clicks, visits, the duration you stay on one page. The advertising industry, which is the real ruler of the network, tries to define, capture and trade this currency through a variety of algorithms, cookies and so on.
The end of the song is that the digital advertising is controlled by middlemen and trackers who invade the privacy of the users. The user pays with his bandwidth and his privacy for advertising, while the creator of a website that emits advertising, thanks to the many middlemen gets only a small fraction of the income. Most of it stays stuck in those ad networks that track user activity.
The browser Brave wants to change this with the Basic Attention Token (BAT). The browser, which has already integrated Bitcoin, first switches off all advertising and spy cookies using an integrated adblocker. Then he measures the attention that a user devotes to a website and pays the BAT to both users and advertisers. With the tokens running on the Ethereum Blockchain, you can buy a variety of advertising materials on the Brave platform, the price of which is given in the users' attention.
So that is understood correctly: With the BAT Brave involved the users in the advertising revenue. If users receive only 10 percent of ad spend, which is about $ 100 billion a year, this is one of the largest non-state redistributions in history, and is itself not much less than the cryptocurrency phenomenon itself.
BAT is traded on several crypto exchanges.
