Zcash is a privacy-protecting, digital currency built on strong science. It allows users to transact efficiently and safely with low fees while ensuring digital transactions remain private. While private, zcash allows users to selectively share address and transaction information for auditing or regulatory compliance.
At the core of Zcash technology are zero-knowledge proofs, which allow transaction data to be validated without revealing information about the amount and the parties involved. Zcash uses specific zero-knowledge proofs called zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge).
Zcash is built on strong science and audited meticulously by third parties. It is an open-source protocol, built by a security-specialized engineering team, and originally based on Bitcoin Core’s battle-tested codebase.

Why is privacy important
Privacy is necessary for ensuring freedom on the internet. When your transactions are being watched — or when your transaction history is available to be known — a person isn’t free to make their own decisions. With other digital currencies, bad actors are able to match people to their balances and details about parties involved, amounts and trends
