The real Zerocoin developer is not even finished with the code yet to create his coin release called "Zerocash". Both of these new coins, Dreamcoin and Libertycoin, came out of nowhere at the same time, both having the words "Zerocoin" in their announcement titles. I went investigating, wanting to invest in one of them if there was any hope of decent returns. I went to Dreamcoin first and discovered the coin dev has already made something like 4-5 coins in the past year, Timecoin, Hashcoin, Matrixcoin, etc. He's basically a serial coin cloner and his last coin was just released in April.
Some people managed to contact the Zerocoin anonymity function creator himself on twitter (lots of different posts and info there):
https://twitter.com/secparam/status/465971947386720256 Both coins are advertised "Zerocoin" while having absolutely no Zerocoin functionality, or even close to it. At best this is false advertising, at worst it's a scam.
Then there were claims of "working with the Zerocoin devs" to implement it in Dreamcoin, here is the Zerocoin developer's official response:
Code inspection of Dreamcoin:
http://pastebin.com/rknTJpWdLet's say you want to invest in Dreamcoin anyway, fully knowing there is no Zerocoin functionality, and that the serial coin cloner dev is either trying to scam you or falsely advertise.
115 full block instamined, love it!
The coin was launched with NO POOL so the dev could just sit there mining alone. I looked up his past coins and those seem to have similar circumstances.
There was a big, false propaganda campaign against Shibecoin because the first 50 blocks were mined by a pool address that went to many different people. Some fat, 50 year old idiot made an article about it on google search claiming a pool address is the dev's address and claiming the Shibecoin dev got it all, when he didn't. This Dreamcoin has the first 115 full blocks probably going straight to the dev's pocket, not a pool, since the coin launched with no pool, and people give it a pass while calling Shibecoin a scam? Are you kidding me?
Next you have the problem that Zerocoin has EXTREMELY complex security vulnerabilities where you're basically required to have absolute trust in the coin creator or he can easily pull Asiacoin type frauds on you. You do not want ANY kind of Zerocoin functionality except possibly from the Zerocash dev himself, and even then, it's still sketchy. The only Zerocoin implementation that will ever be trusted is Zerocash, created by the Zerocoin dev, and even then, most security experts will still probably not trust it due to it's double spend security hazards.
Security Warning: It is critical that the modulus N be generated properly and that the factors p, q and all related information be destroyed. These factors are not needed in the protocol. Moreover, any party who learns these factors will be able to double-spend zerocoins. Note however that knowledge of p, q does not jeopardize the anonymity of Zerocoin.
