> The reason it's currently unlikely is because ad-networks need to validate their views. Ad-networks also want to validate views because they don't trust the hosting website. They don't need to trust the hosting website's server when they can receive a direct connection from the client. However, there is an alternative that fits "serverside ads, binary blob" scenario: the ad-network hosts the website. Obviously the website owner wouldn't want to turn over control to the ad-network, but they don't get a choice when they depend on the ad-network for revenue. Even worse: this isn't a hypothetical concern. Google already tried to implement ad-network hosted websites with "AMP".
