AdChain is a set of interoperable open protocols built on the public Ethereum blockchain that serve the needs of the digital advertising ecosystem. The first protocol under development is the adChain Registry, a decentralized whitelist of non-fraudulent publisher domain names. Other protocols for creative registration and verification, impression tracking, and malware detection, will be added in the future.
