Zcash (ZEC) is the first open, permissionless financial system employing zero-knowledge security.
Total supply 21,000,000 coins. Zcash is a digital currency, or cryptocurrency, like Bitcoin. (In fact, Zcash was built on the original Bitcoin code base.) It was conceived by scientists at MIT, Johns Hopkins and other respected academic and scientific institutions.
You can use Zcash to buy goods and services — it's fast and confidential, great for payments — or you can exchange it for another kind of money, including US dollars, Euros or another fiat currency.
A major difference between most cryptocurrencies and traditional money is that every transaction is tracked and managed on a decentralized, public blockchain, instead of by a centralized institution, like a bank. This means you truly own your money.
