congratulations on getting this up and running zooko and company! i've been following zerocash since the first paper was put out and find it very interesting. while the notion of a totally private cryptocurrency gives me the warm fuzzies, i was apprehensive about the presence of a trusted setup phase when the blockchain is started.
does the trusted setup phase still exist with zcash? i admit that i haven't been keeping up with the latest articles, so i may well have missed one where you have fixed this issue.
