adToken is a protocol token used by the adChain community to keep the adChain Registry free of fraudulent publishers. It is not a transactional currency as it is used for governance rather than exchange. Publishers who wish to join the adChain Registry must purchase ADT for use as a deposit along with their application to join the adChain Registry, and members of the adChain community must purchase ADT to challenge or vote on applications from publishers they believe to be fraudulent.
We see adToken as complementary to BAT. We foresee use cases where adToken and BAT are coupled to provide an enhanced user experience that minimizes opportunities for fraud while protecting user privacy. Also exciting is the emergent design properties that both blockchain-based solutions provide. We look forward to innovative solutions involving BAT & ADT.
