ZCash is a privacy focused cryptocurrency with a decentralized blockchain. It is similar to Bitcoin as a digital currency, however the level of privacy and fungibility is much increased for ZCash.
ZCash publishes all payments on a public blockchain, but does not disclose the sender, recipient or amount of the transaction. Behind this level of privacy and anonymity is the zero-knowledge cryptography tool known as zk-SNARK, developed by the ZCash team of developers.
Privacy is not the only thing ZCash is capable of, as public payments are also enabled. Therefore one can choose whether they would like their transaction to remain anonymous or be publicly available on the ledger.
