AdEx is a decentralized Ad exchange built on the Ethereum network  Focusing on the entertainment industry and video streaming services and publishers, AdEx aims to replace the traditional digital advertising models by providing a transparent, focused solution for advertisers to collaborate with ad publishers directly, skipping middlemen fees and complications. The platform also ensures that the end user can understand and control the ads delivered to them through the use of the AdEx User Profile personalized page. The AdEx token (ADX) is used within the AdEx Platform to buy or sell advertising space and time.
