adToken is a standard ERC20 token on the Ethereum blockchain. Its intended for use in the adChain Registry dapp. adToken (ADT) is a true utility token because it is integral to the functionality of the adChain Registry. In other words, if you were to remove adToken from the adChain Registry then the dapp would lose its operational capability. Furthermore, because of the design mechanism of token curated registries like adChain, replacing adToken with Ether or any other token would not work. This is because the quality of the registry must be tied directly to the value of adToken.
