Better Blockchain Technology

Fungible Cryptocurrency

In order to remain equally interchangeable, units of cryptocurrency must be unlinked from their history so that one unit is as good as any other unit. Zcash brings fungibility to cryptocurrency by unlinking shielded coins from their history on the blockchain.
Enabling New Applications

Zcash is pioneering the use of zero-knowledge proofs, applying cutting-edge cryptography to blockchain technology. Zero-knowledge proofs allow fully encrypted transactions to be confirmed as valid. This new property will enable entire new classes of blockchain applications to be built.
Upholding Confidentiality

In the pre-digital currency world, both individuals and enterprises could justifibly assume that their financial transactions would be kept confidential. With Zcash, users can enjoy the advantages of using a public blockchain, while still being sure that their private information is protected.

Who is behind Zcash?

The scientists, advisors and engineers of ZECC developed and launched the Zcash protocol; this includes all of the authors of the Zerocash protocol, most of the creators of the Zerocoin protocol, and leading researchers of zk-SNARKs themselves.

Zcash finally fulfills an early promise of Bitcoin technology - the ability to transact freely and privately with anyone in the world. This protects the right to privacy held by all individuals on Earth, and opens up new commercial use cases which were impossible without truly confidential transactions.

Technically, it's a challenge to have fungibility in a shared blockchain, yet money requires fungibility. It's exciting to see the Zcash team working toward adding real fungibility to blockchains and with the strength and talent of this team, this is only the tip of the iceberg.

- Dan Morehead | Zcash Investor
Privacy is an essential part of cryptocurrency security, and despite some initial mistaken beliefs to the contrary, Bitcoin alone doesn't provide that. Zcash is the first cryptocurrency that provides the level of privacy users deserve and expect.

- Andrew Miller | Zcash Advisor
Zcash is strongest where Bitcoin is weakest; It gives users the easy ability to maintain their financial privacy. If anything can compete with Bitcoin, it will be on this front.
