AdEx is a trust-minimized protocol for digital advertising aiming at disrupting the existing online advertising landscape and address its significant problems: advertising fraud, privacy and consent to receiving sponsored messages, etc.

The AdEx Platform is built on top of The AdEx Protocol
The AdEx protocol facilitates trading of advertising space or time, as well as the subsequent verification and proof that it actually occurred. Essentially, it covers all interactions between publishers, advertisers and end users. The protocol combines traditional peer-to-peer technology, cryptography and blockchain.
