Love the project and I have been following since the early Zerocoin days. My concern would be the perception of potential back doors. Of course governments want back doors for their own reasons, and in my view will strongly oppose anon currencies in time, that is fairly obvious. They likely have no idea about this tech yet as Bitcoin is still new to them, but once they understand the potential, they will be very afraid of it.
So, how can the community be assured there will be no back doors in Zcash? Will it be open source? Is there some way non code experts can be sure their anonymity is perfectly anonymous? Can the NSA or FBI come to Zcash later and demand that a backdoor is put in? What plans do you have to protect Zcash from this and assure the community this is not a risk? Thank you.
