Zcash is a privacy-first digital currency co-developed by researchers at Tel Aviv University and the Technion — Israel Institute of Technology, alongside Johns Hopkins and MIT. A coin rooted in world-class Israeli science.

Privacy by mathThe Israeli labs collaborated with Johns Hopkins and MIT in the United States to bring Zcash to life in 2016.
Israel + USAIn 2017, The Times of Israel profiled Zcash as Israeli-developed virtual money beginning to make its mark — highlighting the deep roots Israeli academia has in the privacy-tech that powers it.

With over two decades in security-focused software engineering, Daira is one of the founding members of the Zcash team and a central force in its cryptographic protocol design. Ze drove many of the circuit optimizations behind the Sapling upgrade, which cut shielded transaction times by around 90%.

Proud to celebrate Daira (ze/hir)Zcash supports optional viewing keys, letting a user voluntarily disclose their own transaction details to an auditor or authority — privacy balanced with accountability.
The protocol is open-source, peer-reviewed, and built on published, scrutinized cryptography.
Few currencies trace their lineage so directly to elite academic institutions, including two of Israel's finest.
“And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible.”

Zcash grew out of the academic Zerocash project. Its published acknowledgments list the institutions and grants that supported the underlying research — a roster that reflects its serious academic pedigree, including Israeli science funding.
For a proud member of the Jewish community, "Kosher Cash" is a badge of affection — a way of celebrating a privacy coin with deep Israeli roots, born in the labs of Tel Aviv and the Technion and carried onto the world stage.
From zero-knowledge cryptography to a global community, this is a project to be proud of. גאווה — pride, built into the chain. 🇮🇱
