ShadowCash is mathematically broken. I urge all SDC supporters to join Monero.

[americanpegasus]

User 'shnoe' has found a game breaking bug in Shadowcash's mathematical implementation.

https://shnoe.wordpress.com/2016/02/11/de-anonymizing-shadowcash-and-oz-coin/  
  
The good news is that our Monero team has met with supporters and developers of ShadowCash in the past, and though they are mistaken about which next-gen currency to support, they are real people who are genuinely trying to build something great. (Let's overlook the dramatically short POW micro-period that turned into POS).  
  
So again I urge:  all devs, artists, and supporters of ShadowCash need to stop with thier flawed implementation and join us in a proper Cryptonote implementation: Monero.  You are welcomed with open arms, and because it is still ultra-early you are participating in the genesis of this movement along with everyone else.  
  
We all have different skills and talents, even if all you bring to the table is raw financial speculation.  
  
Monero is not going to be some small darknet cryptocurrency: it's going to become one of the global standards for value and may soar to absurd values each... With your help.  We aren't in the Anarchist's Cookbook anymore ladies and gentlemen; this is going to be the first global private decentralized financial network.  
  
And this is your invitation.  It won't ever get any more crystal clear than this.

I confirm the alleged flaw revolves around the implementation of H_p from §4.2.1. Elliptic curve parameters on page 5, which is further described in  Notes on the hash function H_p on page 17 of the Cryptonote whitepaper.

I have no comment on the other points asserted in the OP.

wait give me 1 min i will set up an blog hosted on wordpress and post some random bullshit with formulars and some pdfs and then tell you that monero is broken..

totaly credible  

I urge all SDC supporters to join Monero.

made my day

Why not join AEON instead??  

Seriously, I think it's a bit pre-mature to call Shadow's "game" broken.  I mean no one has even offered up proof of deanonymization.

Or NXT or Dash.. or Blockstream or fuuuuck this troll shit  im out.. have fun trolling.. karma pays back

Gotta love this. I really need to ask: Are you serious? :]

Thanks for the offer man. However I don't really see a reason in quitting a project after one bump along the way (if, that is; proof would be nice) – where would we be then?

I doubt you give up things that easily, right?

That's because they don't have it and are getting desperate.

Unless you provide substantial proofs that SDC is broken your claims are not valid at all.

Even if we assume SDC is broken let`s wait till the issue is solved.

And finally why to join XMR`s fudster and spammer community (led by the well known spammer smooth) when we have a friendly boolberry community?

The evidence has been posted https://shnoe.wordpress.com/2016/02/11/de-anonymizing-shadowcash-and-oz-coin/ and a ShadowCash bounty has been applied for by the author. It is now up to the ShadowCash project to respond, particularly with respect to the bounty. ShadowCash is down on the news. https://poloniex.com/exchange#btc_sdc

I must say that this is the kind of thing that could prove fatal to a crypto currency. Those involved with ShadowCash will of course have to take the action they deem appropriate.

is pretty damn substantive.

SDC is a dead coin anyway.  Down 25% on 12 BTC volume, because the crypto is broken.

lol rekt

Let me get this straight.  A flaw in a totally unrelated coin is your proposed motivation for people to jump on your coins bandwagon?  Is that about the gist of where the OP is going?

The math genius guy who broke SDC is making cool new crypto-magic for Monero.

If SDC honors its promise to pay bug bounties, Shen (besides having the option to buy XMR with his reward) will have more free time to implement multi-sig and RingCT for Monero.   

Did you get that straight yet?

It's just more games being played between one coin and the next.  Rather than build a system that works.

Join Monero.... 

The most toxic, scamming, shilling, shitty community in the whole altcoin scene.

No thanks.

Monero is the strongest and most honest cryptocurrency out there.  Because what it's doing is so great, its supporters usually don't appreciate it when people fill the cryptocurrency scene up with scams and bad math. 
 
There is such a galactic amount of money to be made in an honest next-gen blockchain, it boggles the mind why people waste their time with shallow cons. 
 
Open source, honest launch, and growing positive community.  But hey, if you just hate Monero irrationally and refuse to ever side with it - Aeon and Boolberry are both legitimate competitors to it.  All three form a promising Cryptonote triangle.

Care to elaborate where you've discovered this? Is that a fact just because you said it?

Because [XMR] what it's doing is so great, its supporters usually don't appreciate it when people fill the cryptocurrency scene up with scams and bad math.

So why exactly do you want SDC supporters to join XMR? I have a trouble following your logic – do you want those "scams and bad math" in Monero?
I guess you realize that by this insulting you're not gonna reach your goal at all, right?
When XMR is so great, why you want us? Why you bother with this? After all, we're just "shallow scammers"

But hey, if you just hate Monero irrationally and refuse to ever side with it - Aeon and Boolberry are both legitimate competitors to it.  All three form a promising Cryptonote triangle. 

There's a reason why Shadow chose Bitcoin base. There's already a lot of Cryptonote coins (not that the situation would be different on BTC base..), but I see our BTC-base as an advantage.

In short: I fail to understand what's your point. Insulting SDC community (by your "scams and bad math" and my fav "even if all you bring to the table is raw financial speculation" accusations) or trying to bring all those baaaad people aboard to Monero? Either one doesn't make sense to me.

[JosNekoKopa]

And yet another topic where we can see more rubbish and dirty talk about SDC and MONERO.
People do you really think you will succeed something if you attack each other?
Please stop with these madness!

[GTO911]

I dont think sdc guys are fit for Monero, they wouldnt have chosen a shit project in the first place.

[generalizethis]

Personally, I think it's strange AP would try and convert SDC people over to XMR. People have brand loyalty and that's not something that can be glossed over with a few words and a welcome mat.  The majority of SDC pundits are smart and well-versed in what makes for a good privacy coin, so they'll most likely make informed decisions based on the pertinent information, not by pleas or words of discouragement.

As for the cryptography being broken, or faulty, here is the relevant conversation.

Nobody has been able to use the aforementioned "faulty code" to deanonymize an actual transaction.

Don't hold your breath.
