Zcash

What is Zcash?

Zcash is a privacy-focused blockchain and cryptocurrency. It appeared in response to Bitcoin’s flaws. It used the same algorithm as Bitcoin, but it improved in many ways. Zcash has its own cryptocurrency called ZEC. It has been available for trade since October 2016.

Where did Zcash come from?

Zcash started in 2013 with Zerocoin. It was developed by Matthew Green, currently a professor at John Hopkins University. Zerocoin used a special mathematical technique to conduct blockchain transactions. It is called zero-knowledge proofs. The most important was this proved that the content of transaction was anonymous even though transaction was publicly visible on a decentralized ledger. Although this technique was new, useful and interesting, it had some drawbacks. Zcash claims to improve all these points.

What are the advantages of Zcash?

  • It supports semi-transparent transactions.
    These transactions make it possible to reveal data selectivity. Nevertheless, they don't reveal critical details. Also they can be used in financial marketplace.
  • Protects consumer data.
    Financial transactions in public blockchain are transparent. That makes them less susceptible to manipulation.
  • It has practical utility for businesses that are interested in a system that combines privacy with blockchain technology.
  • Easily accessible mining.
    ZEC can be mined with free GPU hardware.
  • It has a good reputation. So far no serious bugs were found.

Although Zcash seems to be almost flawless, there are some drawbacks. Let's take a look at them.

What are the disadvantages of Zcash?

  • Limited privacy storage options.
    There are limited wallet options for storing and sending ZEC from private addresses.
  • Questionable decentralization.
    10% of the supply is held by team members. So there is a question if it is really as decentralized as they say.
  • Transparent transactions can be tracked.
