The Basic Attention Token, or BAT, is a new blockchain-based digital advertising network that aims to appropriately compensate consumers for their attention while also giving advertisers a greater return on their ad spend.The Brave Browser is used to create this experience, which allows users to watch privacy-preserving advertisements while earning BAT incentives. Advertisers, on the other side, may send personalized advertising to increase engagement and reduce losses due to ad fraud and misuse.BAT's creators believe that by measuring how consumers engage with digital advertising material and preserving that data in a distributed ledger, they can improve the digital advertising experience for advertisers, publishers, and users. Users will see fewer advertisements and on the other hand the material will be more relevant to them.
