Zcash-privacy is the privacy feature of the cryptocurrency Zcash. It uses advanced cryptographic techniques to allow users to shield their transaction data from being publicly visible on the blockchain. This means that users can send and receive Zcash without revealing their identity, their transaction amount, or other details about the transaction. Zcash-privacy is achieved through a technology called zero-knowledge proofs, which allows for the verification of transactions without revealing any sensitive information. This privacy feature is particularly useful for those who value their financial privacy and want to keep their financial transactions confidential.
