This system is a game-changer in the digital advertisement industry where both advertisers and users are in a win-win situation. In this ecosystem, advertisers give publishers BAT based on the measured attention of users. The token is built on top of the Ethereum blockchain and it is the unit of exchange in this new, decentralized, open-source advertising platform. The BAT (Basic Attention Token) was developed to address the inefficiencies and privacy violations of the current digital ad industry. This is the complete list of features available at the time of writing.
