Zcash

Zcash is a decentralized, open-source cryptocurrency that offers privacy and selective transparency for transactions. Payments are published on a public blockchain, but the sender, recipient, and transaction amount remain private. Built on the proven Bitcoin Core codebase by a team of security engineering professionals, Zcash is grounded in peer-reviewed cryptographic research. Its key enhancement over Bitcoin is the addition of privacy features. Utilizing advanced cryptographic techniques, specifically zero-knowledge proofs, Zcash ensures transaction validity without revealing additional details. **How Zcash Works** Zcash encrypts the contents of shielded transactions. To verify their validity without exposing payment information, the protocol employs innovative cryptographic methods. The network relies on zk-SNARKs (zero-knowledge succinct non-interactive arguments of knowledge), a cutting-edge proof structure developed by Zcash’s team of expert cryptographers based on the latest breakthroughs in cryptography. These structures enable the network to maintain a secure balance ledger without disclosing involved parties or amounts. Transaction metadata is encrypted, and zk-SNARKs are used to prove compliance—ensuring no fraud or theft occurs—instead of publicly revealing spending authority or transaction values. Zcash also supports public payments similar to Bitcoin. With compatibility for both shielded and transparent addresses, users can choose to send Zcash privately or publicly. Payments from shielded to transparent addresses reveal the received balance, while those from transparent to shielded addresses protect the recipient’s value.

Zcash is a decentralized, open-source cryptocurrency aimed at empowering economic freedom by providing privacy protection and selective transparency for transactions. It allows users to publish payments on a public blockchain while keeping the sender, recipient, and transaction amount confidential.
