What is Zcash?
Zcash is an implementation of the “Zerocash” protocol. Based on Bitcoin’s code, Zcash intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. More technical details are available in our Protocol Specification.

This software is the Zcash client. It downloads and stores the entire history of Zcash transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.
