This question is an exact duplicate of:
I know that Apple likes to lock down all information associated with Mac/iOS development, but I have a somewhat general question that I'd like to ask regarding the publication of a specific type of application. Is such a question appropriate on StackOverflow, or some where else within the network?
For reference, here is the jist of my question.
I'd like to build a SolidCoin (similar to Bitcoin) thin-client for the iOS, but it won't need to manage the block-chain. Is this allowed by the Apple Developer TOS?
