== History ==
Starting in 2014, the Zcash protocol (briefly known as "Zerocash") was developed through a collaboration between the original [[Zerocoin]] researchers at [[Johns Hopkins University]] and a group of cryptographers at the [[Massachusetts Institute of Technology]], the [[Technion – Israel Institute of Technology]], and [[Tel Aviv University]], who together were able to improve upon the original design by making it more efficient and more private.<ref>{{Cite book|url=http://zerocash-project.org/media/pdf/zerocash-extended-20140518.pdf|title=Zerocash: Decentralized Anonymous Payments from Bitcoin (extended version)|last=Eli|first=Ben-Sasson|publisher=|year=2014|isbn=|location=|pages=}}</ref>

The Zcash project was formally announced by CEO [[Zooko Wilcox-O'Hearn]] on Jan 20, 2016, as an evolution of the existing Zerocoin project (the work of Matthew Green, Ian Miers, Christina Garman, Aviel D. Rubin, at The Johns Hopkins University Department of Computer Science, Baltimore)

{{quote|"With the new Zerocash protocol, unlike the old Zerocoin protocol, users can make direct payments to each other with a vastly more efficient cryptographic protocol that also hides the amount of the payment, not just its origin."}} This new protocol by Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, and Madars Virza produced a coin which would no longer be an “Add-On” to the original Bitcoin but instead would be a new full-fledged digital currency.

The first mining of ZEC was at 17:10 London Time with the release of the 1.0.0 "Sprout" release on October 28, 2016.<ref>{{Cite web|url=https://z.cash/blog/zcash-launch-and-roadmap.html|title=Zcash Launch and Roadmap|accessdate=2016-10-09|author=Nathan Wilcox|date=2016-08-15|publisher=}}</ref><ref>{{Cite web|url=https://twitter.com/zcashco/status/766055061134843904|title=Zcash is set to launch Oct 28, 2016|accessdate=2016-10-09|author=Zcash Company|date=2016-08-18|publisher=Twitter}}</ref>
