I've put some thoughts into possible use cases, here are some that we have been thinking about in the context of decentralized business applications. Some of these concepts are things we are actually working on, others just ideas
- blind auctions (including double dutch auctions) - page-rank style algorithms on top of anonymous credentials or reputations - build a password-based authentication out of any password hash - give out "referral capabilities" that automatically assign a commission to whoever introduced a subscriber who signs up (this would be part of a privacy-preserving subscription service, that could be built on top of a zcash-like (ZSL protocol) cryptocurrency) - consumer credit scores: create a registry of "bad debtors". use zkproofs both to "register" a bad debt/bad action and allow individuals to provide a proof revealing your score without actual transaction details (not sure how exactly this could work) Curious to hear what other people have thought of!
