Hi folks! Can anybody say if I can buy(invest) in ZEROCoin now?
Regards.
Regards.
you should take a look at page 1.

hello surfer43,
its a little bit confusing but believe me, nothing like this will be implemented in Bitcoin
.
so i explain it to you:
old site: http://zerocoin.org/
new site : http://zerocash-project.org/
on the new website you can read:
"Zerocash extends the protocol and software underlying Bitcoin by adding new, privacy-preserving payments. In doing so it forms a new protocol that, while using some of the same technology and software as Bitcoin, is distinct from it. This new protocol has both anonymous coins, dubbed zerocoins, and non-anonymous ones, which, for purposes of disambiguation, we call basecoins."
stay tuned

http://zerocoin.org seems to say that Zerocash will not be a new altcoin, but rather will be implemented into the Bitcoin protocol.
I think this is a wording issue where they just inserted "Zerocash" where they were talking about the original Zerocoin, but I may be wrong. Because http://zerocash-project.org still talks about Zerocash as a new altcoin.
Quote from: zerocoin.org
Zerocoin and the Zerocash protocol operates in the Bitcoin network and is implemented as a series of extensions to the existing Bitcoin protocol. This approach means that Zerocoin can be deployed without relying on a central coin issuer or bank (as used in previous e-cash schemes). Moreover, since no single trusted party operates the Zerocoin system, attacks on Zerocoin must take on a substantial fraction of the Bitcoin network.

So this ever going to exist in real life?
yeah, they want to release it in the end of 2014.

How do you trust Zerocash, when the NSA could serve the creators of the setup parameters with a national security gag order on the eve of the public ceremony?
There are other advanced technical means that might be used to intercept the setup parameters even at such a ceremony, e.g. the NSA can reprogram the microcode of CPUs using built in backdoors and there is technology for jumping the air gap and intercepting the computations inside the computer.
And we will never know if the money supply is being inflated away since the money supply is invisible.

Potentially there is an alternative means of employing Zerocash in an altcoin which could ameliorate the above problem.
If a new Zerocash instance was created periodically, users were allowed to mint instance coins and then unmint (cash out) within a fixed period of time for each instance, then it would clear if the output cash out money supply was greater than the input minted money supply.
Since the creator of the setup parameters is unable to break the anonymity, anyone could create the setup parameters and if the money supply doesn't match after the instance is terminated, then that entity would no longer be trusted.
However there are still several things I don't like about this:
1. The complex unvetted new crypto could still potentially be broken by cryptanalysis over time. (and all the public history of anonymity would then suddenly be revealed to the adversary)
2. What to do if an instance's output money supply doesn't match the input? Ban all those coins? Yuk!
3. The entire thing rests on building reputations and reputation is a slippery slope to centralized hell:

Here's a tutorial for the zk-SNARKs:https://github.com/scipr-lab/libsnark/blob/master/src/gadgetlib2/examples/tutorial.cpp
Very low level, and it doesn't demonstrate circuit loops, but interesting nonetheless. Looking forward mostly for the TinyRAM circuit generator.

Woah, is this for real? http://www.scipr-lab.org/code
The zk-SNARK source code!?!
Came as a sudden surprise.

Well hopefully there is a way to generate the parameters in a trust-less way, they just don't know how yet.
June 25, 2014, 09:42:58 AM
"We're building a system that will not have a back door"... Well there's no way of knowing that the security parameters do not contain a back door, so we have to trust the people who generate them. Hopefully someone will figure out a way to generate them in a provably trustworthy fashion. I don't know if that's possible.
In fact, it is possible to generate the security parameters in a completely trustless manner for the original Zerocoin protocol of Miers et al. (Zerocoin: Anonymous Distributed E-Cash from Bitcoin). All you need to do is generate a number that contains two large prime numbers, and whose factorization is unknown. Amazingly, you can generate such numbers using RSA UFOs, and this is the approach that Anoncoin has chosen for their implementation of Zerocoin.Unfortunately, you can not do the same thing with the newer Zerocash protocol of Ben-Sasson (Zerocash: Decentralized Anonymous Payments from Bitcoin).
