I think this moral panic (for lack of a better term) is omnipresent because it's actually true to some degree. You can't seriously claim these groups wouldn't benefit from anonymous, secure payment systems. However: - They already have anonymous, secure payment systems (cash, drugs, jewels, shell companies, etc) - The cat is out of the bag, so they're going to have it anyway - These proverbial Horsement do more than…

>These proverbial Horsement do more than just move money around; there's still plenty of room for detective work. This. Taking away everyone's privacy because somebody might use privacy to break the law is dumb. You want to bust drug dealers? Bust them for selling drugs.

The response to this will be "yes, but it's only natural to give up some privacy for the greater good", and they'll be right insofar as there's a lot of precedence for this.

- We have driver's licenses, passports and all manner of ID's

- The IRS can audit banking records to ensure there's no tax fraud, sans warrant.

- You can be filmed and photographed in public places for security purposes

The list goes on, and the argument will be that new technologies require new compromises. Yours is hardly a constructive (or even correct) approach to the problem, because it (a) dismisses valid concerns and (b) implies a warped interpretation of privacy law. There is no absolute right to privacy; there cannot be!

That said, we're largely in agreement -- restricting privacy is probably the wrong approach in this particular case, but I think the counter argument should instead be made as I previously described, rather than by a knee-jerk opposition to restricted privacy.

For anyone interested in how Zcash (formely Zerocoin) works and who understands German, I've written my Bachelor thesis about it in 2013: http://www.math.uni-bremen.de/~jhasse/Kryptografische%20Grun... (see Part IV)

Note that the Anonymity section of this describes Zerocoin. Zcash is an implementation of Zerocash which is a later and more efficient, but cryptographically quite different protocol (by the same and additional authors).

For those of you concerned about pump and dump, they've specifically addressed it in a blog post [1]. And they are open sourcing a ton of stuff. But that's addressed in their blog. So to me, the lay man, it seems like they won't be doing a pump and dump. I say lay man because I'm really not qualified to assert that my statements are indeed correct. [1] https://z.cash/blog/funding.html

From that link I see this: > With this approach, the founders are incentivized to support Zcash for the long haul (at least for four years), and they have limited ability to pump-and-dump. I don't see how anyone can audit that statement since the transactions are encrypted [1]. [1] https://z.cash/tech.html

Mining rewards, and the proportion of them that goes to the Zcash company, are transparent (not encrypted).

Oh didn't know that! Thanks :) I thought that Zcash was just a new name ;)

Nothing new here. Add it to the pile of hundreds of other altcoins. Why is this here? Feels like the pump-and-dump world of altcoins is being done here to pump up this post.

Well, I was wrong.

I suppose when you see so many scams, you rely on instinct. But had I read more of the site, I would have realized that Zcash really is something different.

So what did I do? I relied on Cunningham's Law: "the best way to get the right answer on the Internet is not to ask a question, it's to post the wrong answer." I rarely notice my karma score going up, but I certainly notice it when it goes down. That caused me to look at the comments and figure out why.

So I learned something :)

> Why is this here? Actually there's a precise answer to that. In yesterday's popular Keybase.io thread, the submitter (rdl) said "Along with Zcash, it is the most amazing crypto-engineering project I've seen in years." https://news.ycombinator.com/item?id=11037297 That was evidence the community might find it interesting, and the project hadn't had discussion on HN yet, so we invited an earlier submitter (malgorithm…

You're right :) Thanks for the constructive rebuke.

I don't think they will actually control anything, once it takes off; just like no single entity really controls Bitcoin.

> just like no single entity really controls Bitcoin. That's just not true. The core developers do control it. Look at the problems its having with the blockchain limit. Yes in theory anyone can fork it and people can run the fork, but that theory has now been tested and it failed. Similarly, if ZeroCash took off, the "official" devs would be the ones to control it. And they're a for profit company on top of it. I ca…

You mean like the US Dollar?
