What is Zcash?

Zcash is an open-source cryptocurrency that enables users to send and receive digital money securely. It runs on a blockchain network maintained by a global community of computers. The project distinguishes itself by prioritizing user privacy as its main feature.

How Does Zcash Work?

Zcash uses a cryptographic tool called a zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge). This technology allows the network to verify that a transaction is valid without revealing any sensitive information about the sender, receiver, or amount.

Transparent vs. Shielded Transactions

Users can choose between two address types. Transparent addresses (t-addresses) work like Bitcoin's, with transaction details publicly visible on the blockchain. Shielded addresses (z-addresses) use zk-SNARKs to keep transaction data completely private and encrypted.

Security and Decentralization

The Zcash network is secured by a proof-of-work consensus mechanism, where miners compete to solve complex puzzles to validate blocks. This decentralized approach ensures no single entity controls the network, promoting security and resistance to censorship.
