Zcash (ZEC) is a privacy-focused cryptocurrency that offers enhanced security and anonymity for users' transactions. It employs advanced cryptographic techniques, specifically zero-knowledge proofs known as zk-SNARKs, to allow transactions to be verified without revealing the sender, recipient, or transaction amount. This ensures that Zcash provides optional privacy features, enabling users to choose between transparent and shielded transactions, thus combining the benefits of public blockchain transparency with enhanced privacy. Zcash is designed to provide strong encryption to protect user data while maintaining the decentralized and secure nature of blockchain technology.
