Zcash ( ZEC) is a decentralized open-source cryptocurrency that ensures privacy and selective transparency of transactions. Zcash coin payments are published on the public blockchain, but the sender, receiver and transfer amount remain confidential.

The level of anonymity of Zcash is noted by many well-known companies and individuals. For example, WikiLeaks began accepting donations in Cash, Edward Snowden called cryptocurrency the most interesting alternative to Bitcoin, and Europol officially expressed concern about the increasing popularity of cryptocurrency.

What is Zcash?

The emission capacity of Zcash coin makes out 21 million coins, new blocks with the size of 2 Mb are being created every 2.5 minutes. The block reward makes out 12.5 ZEC and will be reduced twice every 4 years starting from the moment of launch in October 2016.

The main technical peculiarity of Zcash is the use of the zero-knowledge proof, which allows to confirm transactions without disclosing additional information and makes the use of the crypto currency totally anonymous.


“Thanks to the New zerocash Protocol, unlike Zerocoin, users can make direct payments to each other using a much more efficient cryptographic Protocol that hides not only the origin but also the amount of the payment”.”

The zcash for the project was officially announced as the Executive Director Zuko Wilcox. January 20, 2016 as the evolution of the Existing zerocoin project (work of Matthew green, Ian Mayer, Christina Harman, Aviel D. Rubin, Johns Hopkins University, Department of computer science).

With the use of the new Protocol appeared independent cryptocurrency Zcash (ZEC), ceased to be a “Supplement” to bitcoin. On October 28, 2016, Zuko Wilcox held the official” cryptographic ceremony “ of the Zcash launch.

Zero-knowledge proof

Zcash coin uses a specific type of the zero-knowledge proof that is called zk-SNARKs. For that end, in a Zcash transaction a data string (“key tuple”) is generated by the sender, which consists of a spending key, viewing key and billing address.

A sender cannot generate this string unless he possesses spending keys or the values of sending and receiving are not equal. Zk-SNARKs also creates a unique nullifying function, which marks the tokens as spent after the transaction completion.

Usually, a collection of a billing address, viewing and spending keys is encrypted and unavailable for users. In this way, the transaction check with the keeping the confidentiality of its details is carried out. However, Zcash can carry out public transaction too, providing all data of keys in this case.

Rewarding of founders

The investors who invested funds in the creation of Zcash will all together receive 1.65%, the founders, employees and consultants — 5.72%. Another 1.19% will go to the “Strategic Reserve of Zcash Company”, while the remaining 1.44% will be received by the non-commercial organization Zcash Foundation, founded in May 2017. The strategic reserve will be used for financing of a new project that will increase the value of Zcash Company and the task of the Foundation is to support and maintain the Zcash protocol.

Zcash perspectives

Due to a complicated mechanism of Zcash transactions, they take much time into account — up to 1–2 minutes, while traditional cryptocurrencies spend several seconds on it. In September 2017, the developers announced that they have created a new zcash algorithm that makes the generation process of zk-SNARK five times faster. The software update must be released in 2018.

At the beginning of October, the Waves Platform added new gateways or Zcash and Litecoin. The management of Zcash announced that they plan to develop the cryptocurrency in the Asian market, having announced the entry into Bithumb, the South-Korean exchange.
