ZCash backdoor?

[cryptimus prime]

Alphabay implement Zcash and they are down?
Coincidence or backdoor?

Is that paper available anywhere?

As if we needed any more reasons to boycott ZionistCash and it's 20% premine.

Here is what Green said how they could build a backdoor into Zcash: https://www.newscientist.com/blogs/onepercent/2013/03/bitcoin-zerocoin.html

This was back in march, so maybe now the backdoor is already in Zcash.
So basically they can make every transaction visible, even the "anonymous" transactions. Great coin.

Thanks for the link. Glad I never put any penny into this one.

Regardless of whether this is true an anon coin with a dev team that receives direct financial compensation from the use of said anon coin never sat well with me in regards to the possibility of criminal liability and therefore this type of stuff.

Me too I dont see an utility for an anonymous coin which is deanonymized by the developers through a backdoor. Add to this the trusted setup which can allow them to print coins endlessly and you have a deep flawed useless coin.

I'm feeling distrustful of all the altcoins, they suffer too much influence from bitcoin, if bitcoin drops, most altcoins also decrease. Zcash too.

[eXpl0sive]

Like we needed any more reason to stay away after 20% premine.


EDIT:
Was the backdoor in the seed? If so, ZClassic also has the same backdoor?

This was what I was wondering.  I think its safest to assume that all the forks would be susceptible to the same insecurities.

How anyone could trust Zcash after Zooko essentially admitted that it had a backdoor in one of his tweets is beyond me.

Because in 2017 not have rules trading as 2015-2016, the rules of cryptocurrency market in history is: "Bitcoin up, Altcoin down and Bitcoin down, Altcoin will up!" but checking again the price in 2017 helps me. This rules has been broken and when Bitcoin growth, altcoin will rising up too and strong than Bitcoin, as XRP from @500 sats to @25.000 sats, ETH from $10 to $400, DGB from @50 sat to @2600 sat ... lol. And at now, if you compare with this rules I said, you can understand the market

Your theory is absolutely absurd. ZCash has been on the market for a long time now, and any backdoors would have been immediately noticed by other contributors.

Very, very few people truly understand how Zcash works. Even Zooko can't explain it. A backdoor could be something as simple as a vulnerability that they either accidentally found, or intentionally placed, and then kept secret. It's not like there's a big "THIS IS THE BACKDOOR!" comment in the code. It would be an extremely obscure vulnerability, that could then be used to deanonymize transactions. Considering that the founder essentially admitted there are ways for them to make Zcash useless for criminals, it's far from absurd to say that Zcash has backdoors. To me, it's practically 100% certain that they're there.

Guys, ZCash is the first cryptocurrency which is using ZKsnarks. Cryptography is not always easy to explain. If you really wont to figure out what ZKsnarks means (and you have deep understanding in math) then check the listed papers in https://en.wikipedia.org/wiki/Non-interactive_zero-knowledge_proof. It would be great if someone out there finds the proper words to explain ZKsnarks to the world.

Come on. You know, and I know that a backdoor would have been sealed long ago, if it had even a chance of existing. ZCash had, and will continue to have a bright future.

Sealed by who? There are very few people outside of the Zcash team who could even explain how ZK-snarks work, let alone review the code for backdoors. Bitcoin was built with well understood cryptography, and there were still serious bugs many years in. The best well known one was in August 2010, when someone found and used a number overflow exploit to generate 92 billion Bitcoins. Obviously, it was fixed, but my point is that if something like that can happen in Bitcoin, which as I said uses well understood cryptography, you'd have to be naive to think that it couldn't happen in Zcash.

The cryptography used by Zcash is so new, and so complex, that it would be trivial for the Zcash team to place a backdoor without anyone noticing it. And given that several Zcash team members have made statements supporting backdoors, I think it's a near certainty that such a backdoor exists.

[cryptimus prime]

Wrong. Why is it so difficult to understand that the main people behind Zcash (Zooko, Green) openly confirm a backdoor in Zcash without even hiding their plans?

So no, they wont seal it but open the backdoor it by themself. Also a backdoor does not need to be lot of code but simply a vulnerability. This makes Zcash worthless.

How about we don't be early 1900s Europe style racist towards Jews? Just a thought. For sure, if you're doing small to medium business ethnic loyalty might cross your mind - "I'm not Chinese, but they all are, will they favour themselves over me?" sort of thing. I think that's completely irrelevant to holding a cryptocurrency that the developers obviously want to rise given their 20 per cent stake.

I know of no ZCash back door. I do know there is no chance of a cinder in snow that governments around the world will allow large-scale, untraceable money transfer.  It's called money laundering, and they seem not to like it. The easiest thing would be just to ban possession of a cryptocurrency if it got out of control. Or they might just regulate the gateway where it turns back in to fiat, which would irritate people less. They'll probably start with this less drastic measure.

As if we needed any more reasons to boycott ZionistCash and it's 20% premine.
