AdEx

AdEx Network describes itself as a new-generation solution aiming to address and correct some of the most prominent inefficiencies of the online advertising industry.

AdEx originated in 2017 as a decentralized ad exchange and subsequently evolved into a full protocol for trading of advertising space/time and the subsequent verification and proof of ad delivery. It covers all interactions between publishers, advertisers and end users.

AdEx Network works through micropayments on Ethereum by utilising the OUTPACE layer 2 payment channels, and offers DeFi staking of its native ADX token.

The AdEx team also develops an open source platform built on top of the Ethereum implementation of the protocol. Since the public launch of the platform in 2020, it has gained more than 4,000 registered users and has processed 800+ million micropayments on the blockchain.

ADX is the native utility token that is used for incentivizing validator uptime and ensuring the smooth running of all advertising campaigns on the AdEx platform.

Validators are appointed for each advertising campaign on the platform, and are responsible for processing the micropayments between publishers and advertisers through layer 2 payment channels. The more tokens are staked, the stronger the reliability guarantees of the validator network. As of late 2020, the staking APY is over 50%.
