AdEx (ADX)

AdEx Network describes itself as a solution that aims to address and correct some of the most prominent inefficiencies of the online advertising industry, such as user privacy misuse, ad fraud, and lack of transparency in reporting.

AdEx originated as a decentralized ad exchange and subsequently evolved into a protocol for decentralized digital advertising. The protocol facilitates the trading of advertising space/time, as well as the subsequent verification and proof of ad delivery. It covers all interactions between publishers, advertisers, and end-users. The protocol combines traditional peer-to-peer technology, cryptography, and blockchain.

The AdEx team also develops an open-source platform built on top of the Ethereum implementation of the protocol, available at (platform.adex.network). With its in-house developed OUTPACE payment channels and the ability to process micropayments for each individual impression, AdEx claims to have become the largest payment channels network on Ethereum. It is currently processing an average of 70 million transactions per month.
