Z.Cash VS DASH

Pantera capital posted this on their blog. It seems they're also one of the investors. This only validates DASH and the need for a fully fungible cryptocurrency. Also, having an established VC among shareholders only tells me that there will be more willingness to insert a backdoor into the software, to play nice with governments and gain acceptance all while lying to people about it just like so many companies like Cisco, Microsoft, Google and others have done. When all you care about is making money the end results are so painfully obvious. It's in their best interest to play nice with governments and introduce a backdoor all while lying to people about it, playing both sides basically.

Z.Cash will use one master privatekey which could unmask all the transactions. If they give gov access to that key, the whole house of cards comes crushing down. It doesn't matter their code is open source. That won't prove anything in itself.

Portfolio Developments

Zcash

Our latest portfolio company Zcash is announcing the launch of their public alpha release. Zcash is the company behind the implementation of the Zerocash protocol, a way to provide completely anonymous cryptocurrency transactions. Users may transact between each other directly, without revealing the origin, destination, or amount of the payment.

Transactions are verified by zero-knowledge proofs, a mathematical means by which to prove a something with very little information (information, in this case, which does not include much transactional metadata). If Bitcoin is HTTP for money, Zerocash is HTTPS. A user can forgo his or her own privacy and reveal proof that the transaction was his or hers, a la selective disclosure. Transaction metadata in the blockchain is confidential by default but can be revealed under specific circumstances. This allows the best of both worlds, strong privacy and blockchain-caliber transparency.

Zcash published its source code on Github and is now allowing anyone to test out the software. It is a “testnet” and not allowing movement of any actual money yet. The launch, which will enable transactions of real value, is about six months out.

Zooko Wilcox-O’Hearn, a computer security specialist who has designed multiple network protocols that incorporate concepts such as self-contained economies and secure reputation systems, heads the team. The team includes highly talented engineers and scientists, one of whom is Matthew Green, one of the investors of the Zerocash protocol and an expert in applied cryptography and network security. The project has garnered support from many of the blockchain elite such as Gavin Andresen, Greg Maxwell, Nick Szabo, Adam Back, and Vitalik Buterin.
