Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy and anonymity through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. 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 block chain has reached a significant size.

See important security warnings in doc/security-warnings.md.

Zcash is unfinished and highly experimental. Use at your own risk.

We have a guide for joining the public testnet: https://github.com/zcash/zcash/wiki/Beta-Guide
