Zcash

Zcash is the future of money-- digital, decentralized and private. It is an implementation of the "Zerocash" protocol; a digital currency based on Bitcoin's code, but with a higher standard of privacy. Like Bitcoin, Zcash transaction data is posted to a public blockchain. However unlike Bitcoin, your personal and transaction data stay completely private. Thanks to a sophisticated zero-knowledge proving scheme, transactions can be verified without showing any information at all about the sender, receiver or transaction amount. Selective disclosure features are available for users who may need these for compliance or audit purposes.

Zcash was built by top cryptographers, with an underlying protocol based on the research of scientists from MIT, Technion, Johns Hopkins, Tel Aviv University and UC Berkeley.
