The Zcash team announces the roadmap to Sprout: https://z.cash/blog/sprout-roadmap.html
Wasn't the launch supposed to be July ?
May we know what are the constraints for the delay ?
maybe because it is hard to code something like zcash? i'm just guessing
(launch date at the moment: september)
Yes, we earlier planned for a July release. There are three reasons it's gotten pushed back: we inserted a test framework milestone, we added a "payment API" feature goal, and we spaced out the later milestones to account for security audits and a lot of time for beta testing.
I just updated the FAQ, thanks for catching that.
