AdsDax is a blockchain-enabled marketplace to create, verify, optimise, buy and sell advertising at low fees powered by its own cryptocurrency, the OYou Token. AdsDax aims to be the first platform that can be used by anyone to design develop and create any rich media advert and turn that into a smart ad contract for audience targeting that can be fulfilled by publishers and consumers without the need for any middleman and with full transparency and payment to publishers who provided the ad space and consumers who engaged with the ad.
