RefToken is developing a decentralized affiliate program that will connect DApp developers with marketers that will distribute their DApps to users. Their smart contract enabled network will be powered by the Ethereum-based REF token, which will be bought by merchants and held in escrow by RefToken. Marketers will then be paid for each conversion that they deliver, according to the terms of the predetermined smart contract. The network will implement a review and rating system.

DATx is cooperating with Avazu to develop a blockchain powered digital advertising platform with cross-chain capabilities. It will have a hybrid model of, centralized and decentralized data storage, that will give users more control of their personal information.

DATx will also use transparent machine learning algorithms, decentralized auditing, and incentives based on user attention, to help improve the inefficiencies that currently plague digital advertising.
The network is powered by the DATX token, and is backed by several influential firms, such as Genesis Capital, Qtum, and Game.com.
