It's not true. Zerocash will be open-source project which mean everyone can analyze its source code. No backdoor can be hidden.

Darkcoin is a Bitcoin clone which was released with basically no changes at all to the system, but with CoinJoin (https://bitcointalk.org/index.php?topic=279249.0) privacy as a sales pitch.
It's certantly not the first time that I've posted about something technical where some altcoin then popped up with it as a sales feature on its whitepaper without even bothering to implement it. :-/
The funny thing is that CoinJoin's primary advantage is the network support for it is already part of Bitcoin since day one. Maybe it's not /completely/ pointless to launch a new cryptocurrency around CoinJoin simply because a commitment from a lot of users to use it might increase the anonymity set... but as far as I can it's nearly completely pointless (esp since in Bitcoin some ordinary transactions look like CJs).
If you're going to do something incompatible at the protocol much better can be done— as shown in practice by Bytecoin, or in theory in ZeroCash and ZeroCoin. ... even there isn't not a requirement to start up a whole new currency for it, but at least not pointless. CoinJoin isn't the be all end all of transaction privacy, but at least you don't have to switch currencies or convince people to deploy improvements to Bitcoin in order to make use of it.

Why wait for darkcoin v2? I mean if its just copying stuff in bytecoin then you can already use that.

sorry,aber die Linien sind nicht korrekt gezogen.Der Kurs kratzt gerade mal am downtrend, den ich mal als bullishes Dreieck oder gar als bullische Fahne bezeichnet habe.
Der (hoffentliche) Durchbruch kommt erst in etwa 4 Wochen

was bedeutet eigentlich der Name Sockpuppet ? Wieso hat der Ausruck was mit Mehrfachanmeldungen zu tun?

Sockenpuppe ?!
