Based in South Korea, Bithumb listed Zcash, a privacy-centric digital money based on a blockchain, a public accounting ledger that tracks virtual currencies, allowing people to buy and sell them without the need of a middle-man like a bank.Fortune - Read More
If someone were to get their hands on a complete copy of all the shards, it would enable them to surreptitiously create counterfeit coins, an attack that would be difficult to detect given the anonymity of zcash transactions. So, to secure the final product, the full private key was broken up into six pieces, each generated in a different location.CoinDesk - Read More
Zcash engineer Sean Bowe and cryptographers Matthew Green and Ian Miers (all of whom also work for the for-profit Zcash Company) are releasing a living prototype of a new form of zk-SNARK that could lead to huge improvements in speed.CoinDesk - Read More
Last November, journalist Morgen Peck showed up at her friend Molly Webster's apartment in Brooklyn, told her to take her battery out of her phone, and began to tell her about The Ceremony, a moment last fall when a group of, well, let's just call them wizards, came together in an undisclosed location to launch a new currency. It's an undertaking that involves some of the most elaborate security and cryptography ever done (so we've been told). And math. Lots of math. It was all going great until, in the middle of it, something started to behave a little...strangely.Radiolab - Listen
“By adding the Zero-knowledge Security Layer into Quorum, we are able to explore how state of the art cryptographic privacy technology will enhance the next generation of financial services applications,” said JPMorgan executive director and blockchain center of excellence lead architect Suresh Shetty in a statement.Forbes - Read More
As banks explore the potential of blockchains, they’ve been quick to surmise that the technology, as it was originally designed, does not provide robust privacy. When Satoshi Nakamoto invented bitcoin in 2009, he (or she or they) provided a way for multiple participants, who have no reason to trust each other, to work together in maintaining a canonical, tamperproof history of transactions and digital messages. But the design required that all activity be exposed for anyone to see...American Banker - Read More
Each Bitcoin user has an address, made up of letters and numbers, and the authorities are often able to link an address to a real person using sophisticated data analysis. In contrast, Zcash uses a method developed by a team of cryptographers working at M.I.T. and in Israel — known as zk-Snark — that allows transactions to be confirmed by the network without anyone recording the Zcash addresses involved in the transactions.The New York Times - Read More
Zcash’s code is also open-source, but its inventors have formed a company and accepted money from investors. In addition, 10% of the 21m coins to be issued are earmarked for founders, investors, employees and a putative Zcash foundation. All this, says Mr Wilcox, is to align incentives for all involved, allow the firm to hire a great team and enable quicker decisions...The Economist - Read More
Privacy is an essential part of cryptocurrency security, and despite some initial mistaken beliefs to the contrary, Bitcoin alone doesn't provide that. Zcash is the first cryptocurrency that provides the level of privacy users deserve and expect.
Privacy is crucial to modern business. If Apple and Samsung can view each other's financial transactions, the system is not secure. Zcash provides that secure, neutral ground for commerce.
Many of us at ConsenSys believe the Ethereum community should be excited about the launch of Zcash and the incredible partnership opportunities that exist to bring both blockchains closer to achieving our goals....ConsenSys Media - Read More
For banks intrigued by blockchains but leery of volatile, decentralized digital currencies, Wilcox's company, Zcash Electric Coin Co., is developing enterprise software that would add an encryption layer to a private shared ledger. It's called ZSL, for Zcash Security Layer — Wilcox has likened it to Secure Sockets Layer, the encryption technology developed in the mid-1990s that made communications on the web safe for online banking.American Banker - Read More
Zcash is — like Ethereum was — a fundamental technological advance, not just a new project using the same technology. The prospect of truly anonymous transactions may sound alarming to some, but in a world in which privacy withers further away every day, it can also sound a lot like a reassuring bulwark.Tech Crunch — Read More
Anonymity achieves [fungibility] by preventing merchants or service providers from seeing any blemishes that might prevent them from honoring a unit of currency. Reducing the opportunity for external judgment is pretty much the goal of privacy protection in general. Ideally, so little information is revealed that everyone — and every valid transaction — is treated equally.Bloomberg — Read More
There are strictly technical considerations that make strong privacy a necessary feature in a digital currency. Ideally, for the system to function, coins should be fungible, which is to say, each coin should be indistinguishable from the next. When a coin carries the history, and potentially the smear, of every past transaction—as bitcoins do—this can be difficult to achieve.IEEE Spectrum - Read More
It’s clear that the availability of a truly anonymous cash system is desired by the vast majority of the digital currency community. This sort of cryptographically-ensured privacy should become more usable over time. Perhaps the currently-available testnet version of Zcash should be viewed as an early preview of what’s to come in the future of privacy-conscious digital currencies.bitcoinmagazine.com - Read More
The Zcash team is doing much needed work. Protocols like this are the ideal building block for p2p electronic cash.
Zcash is an important project being worked on by a very talented team.
We are doing Bitcoin + privacy. Because nothing else has the empirical evidence of having worked after being under attack for years and years.Epicenter Bitcoin Podcast - Watch
Bitcoin may have become the currency of choice for the anonymity-loving Internet underground. But it’s never been anonymous enough for Zooko Wilcox. As he’ll remind anyone who’ll listen, the blockchain, bitcoin’s very public ledger of all transactions in its crypto-economy, means that...Wired.com - Read More
Bitcoin was built using decades-old cryptography; I'm excited to see what is possible when a great team applies the latest advances to create a better digital cash.
There is a strong need for research into better fungibility in digital currency systems, and Zcash is an ambitious project that goes far beyond the incremental improvements worked on elsewhere.
Bitcoin is so special and does something that nothing else does, and therefore, we can take our time or not worry too much about some aspects. I think that’s really wrong.coinjournal.net - Read More

Bitcoin is HTTP for money; Zcash is HTTPS.
The Zcash team has been been working away quietly and diligently on something very, very important: fully private and fungible digital cash.
Bitcoin is dead. Or, not. We don’t know what the future holds, but what we do know is the pioneer in the cryptocurrency movement is in some trouble. In periods of trouble, companies either fix their flaws, either real or perceived, and bounce back, or they’re quickly replaced by a better alternative. Zcash is one such alternative...thenextweb.com - Read More
Technically, it's a challenge to have fungibility in a shared blockchain, yet money requires fungibility. It's exciting to see the Zcash team working toward adding real fungibility to blockchains—and with the strength and talent of this team, this is only the tip of the iceberg.
Privacy is a very important challenge with current blockchain technology, but existing solutions like private blockchains do not really solve the problem. The technology behind Zcash does.
In the game of anonymity, cryptocurrency fans have embraced Bitcoin and the blockchain technology which drives it. The technology does record and stamp the transaction, and is placed in the cloud, unlike Zcash, which sees its alpha release....cryptocoinsnews.com - Read More
As much as people now love the idea and the benefits of blockchain technology, time and time again they bring up two issues that blockchains currently do not address: scalability and privacy. I believe that the technology that Zcash is working on is currently the best in class in its ability to address the privacy challenge.
I think the right to privacy is important in all aspects of life, including financial transactions, and Zcash is the ultimate currency for privacy.
The added privacy could make Zcash a more viable choice for financial institutions and consumers than other cryptocurrencies.fastcompany.com - Read More
Zcash is strongest where Bitcoin is weakest; It gives users the easy ability to maintain their financial privacy. If anything can compete with Bitcoin, it will be on this front.
The fully private Zcash is to digital currencies what Bitcoin was to money—a monumental innovation. Something truly comparable to physical cash has been born online.

The lack of fungibility of Bitcoin has always been a looming threat to its economics. Zcash finally solves that problem, using one of the most fascinating cryptographic techniques ever developed. Since the protocol was first discussed, it was obvious to me it would be a hit; it was merely a matter of getting the right team to see it through. I believe the Zcash company has done just that.
Zcash is revolutionizing the world of finance with technology that guarantees trust without sacrificing privacy.
Zcash has the most innovative technology that will revolutionize how the world manages data privacy.
