Zcash is an implementation of the Zerocash cryptographic protocol operating over a block chain provided by a fork of the Bitcoin source code. Sitting between the two is the Zcash protocol itself.


Zerocash is a peer-reviewed cryptographic protocol providing decentralized anonymous e-cash on top of a block chain. The details of this protocol, along with a proof of security, can be found at http://zerocash-project.org/paper.

Zcash Protocol


The details of how to integrate the Zerocash cryptographic scheme into a Bitcoin consensus protocol are crucial to overall usability, security, and performance. Zcash includes important security fixes and functionality enhancements relative to Zerocash, as well as a new proof of work. This specification is a work in progress.
