I just wanted to open a discussion on potential future applications of Zcash...
Throwing out a couple off the top of my head;
1) Maybe some type of decentralized credit monitoring system that maintains user privacy? (Current credit scoring system in the US is very centralized, run by Equifax, TransUnion, and Experian) Could it be worth writing a new system that can be sent inquiries and handled only by the user?
2) Is there a reliable, provably fair Zcash Dice game? Although a fairly small idea, things like this will get potentially many more transactions onto our blockchain, which we need if we want true value to rise; I personally believe that any given cryptocurrency's true value is equal to it's volume, minus the amount of coins outside of circulation.
