About Zcash (ZEC)

Zcash is a cryptocurrency and blockchain that offers strong privacy.

Zcash was launched by the

Electric Coin Company

(formally, the Zerocoin Electric Coin Company, LLC) in October, 2016. Zcash is a fork of

Bitcoin

and runs on the Zerocash protocol, which was first described in a

white paper

published in 2014 and subsequently developed over the course of several years by

Zooko Wilcox-O'Hearn

and various professors and academic researchers from MIT, Johns Hopkins University, the Technion, and Tel Aviv University. Initial research on the Zerocash protocol was funded in part by DARPA, the U.S. Air Force Research Laboratory, and the Office of Naval Research.

Token

Zcash (ZEC), or ZEC coin, is the digital asset token of the Zcash Network (similar to how bitcoin or BTC is the digital asset token of the Bitcoin network). All ZEC balances and transactions are recorded on the Zcash blockchain. The smallest subunit of ZEC is the “zatoshi,” which is 10-8 ZEC or one hundred-millionth of a ZEC (0.00000001 ZEC). Zcash can be bought and sold for fiat currency or other digital currencies.

Zcash can be bought and sold for fiat currency, e.g. ZEC to USD and vice versa, or other digital currencies. Zcash can be purchased on a

cryptocurrency exchange

and stored in a Zcash wallet, or in a

crypto wallet

with a regulated exchange and custodian like Gemini.

Supply

The supply of Zcash is deterministic, unlocked with Zcash mining, and fixed at 21 million ZEC. The supply schedule is embedded in the Zerocash protocol. Like all cryptocurrencies, Zcash price prediction is based on a variety of macroeconomic factors and crypto-market dynamics.

Characteristics

If bitcoin resembles “digital gold” (i.e., a store of value), then Zcash is akin to “digital cash,” which offers privacy features similar to those afforded by credit card and debit card transactions, ACH and wire transfers in the U.S. banking system, and international wire transfers on the SWIFT network.

Privacy Technology

Zcash’s unique value proposition stems from the fact that its encryption technology, known as zero-knowledge proofs or specifically

zk-SNARKs

(zero-knowledge succinct non-interactive arguments of knowledge), permits users to keep the details of their financial transactions confidential and out of the public eye, while at the same time providing transparency to regulators and financial intermediaries who custody and support the trading of Zcash.

Transaction Types

Zcash supports four transaction types: public, shielding, deshielding, and private. A public transaction happens between two “transparent” addresses or “t-addresses” and behaves exactly like a Bitcoin transaction — the amount transferred is publicly visible on the Zcash blockchain. A shielding transaction happens between a t-address and “shielding” address or “z-address.” The balance of the t-address and the amount transferred out is public, however, the balance of the receiving z-address is private. A shielding transaction happens between a z-address and a t-address. The balance of the z-address is private, however, the amount transferred out and the balance of the receiving t-address is public. A private transaction happens between two z-addresses. The balance of both z-addresses and the amount transferred between them is private. The following image illustrates the four different Zcash transaction types:
