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

1. The bug itself was an error that any very amateur cryptographer could make (that would include me) if they were foolish enough to try to implement this without any sort of help or review from a competent cryptographer or mathematician (that would not include me). That still foolish, but perhaps understandable given limited resources and a mandate to implement the promised features anyway.

The known log is not the reason for the SDC lack of anonymity (rather it's plain old commutative property of multiplication), but this paragraph describes a good rule of thumb.

So on a scale of complete dumbass to blithering idiots, how badly did the SDC team fuck this up?

2. The "SDC Deanonymized? Nope" blog post was an epic and complete fail on the level of blithering idiots who are also complete dumbasses. That includes the claim of not being able to reproduce the flaw in 10 hours of trying. I'm not sure I believe they even tried, or which would be worse.

Don't know if this is just a way to attempt to pump it a bit more, or if they fucked up THAT bad.

I'm in the delete bot on the shadow thread. It is a mark of honor. It means I know shit when I see it.

First and foremost, that code hasn't been implemented yet into the main chain of Monero.

It hasn't been implemented in any chain whatsoever.

That is purely R&D work on cryptography. Maybe that's how he came across the math issue, I don't know the details.

@erok There is no such bug in Monero itself. It uses the proper method for key images, not the incorrect one.

I guess it's a good thing I didn't run a PR campaign around it then. Tongue

Then again, that's not the type of guy I am.

You appear to be the type of guy that is butthurt that you are invested in a broken cryptocoin and someone found a pretty big bug in SDC.

It's better to have the truth out about the technology you choose to use than to have it swept under the rug....like DASH.

I say let sdc fix the issue if they can and go after xmr devs to show them.. Ofcourse pay the bounty first.. Let the best team learn and win.. And then later some evil genius will break both and we learn the hard way that anon in the current context wont work:) atleast according to annonymint.

So shen was working on a Monero bug a week ago:
https://github.com/ShenNoether/RingCT/commit/6640e808018bb47ea34fd112dbf2d2bef9c1156b

Which got pulled into Monero 6 days ago:
https://github.com/monero-project/research-lab/commit/b215a98a749c452c0a0336ab4ee93b1d71df2e78

/research-lab/ isn't the main Monero repo.

If ShadowTrash refuses to pay Shen for his work, I'll cover the bounty myself.

It's unforgivable SDC would advertise rewards for bug hunters, then renege.

So it hasnt been patched yet?! And you guys think its a good idea to attack another crypto?! Also the bounty is being paid you moron (from what I read in slack).

I don't think SDC can patch this. It's de-anon'd the entire chain. Better to start over, with some good crypto.

The bug doesn't exist in Monero. The commit for our Research Lab repo is for documentation purposes.

I'm glad SDC is (reportedly) doing the right thing and paying Shen. It's a good thing they didn't listen to the "there's no problem here" hand-waving denials.

The market wasn't released yet. There were few transactions at risk and probably none that could implicate anyone. Monero however has risk associated due to, as you all put it, "used by more people". SDC can fork no problem but damn you guys haven't even figured out how to fix it and haven't told anyone yet? You all still have the patch on the testbed?

Should I start 4 reddit threads in 3 different subs, a blog, and a dedicated thread while trollfag'ing your main bitcointalk thread on a couple accounts? No, because I'm not that dude. STFU about me and SDC pls.

Patched how? Like I stated earlier, that is a testing branch which has not been merged nor implemented yet to the main/master branch of Monero. That branch is specifically meant for testing currently. Any bugs there won't influence Monero currently.

Then he decided to take the crosshairs to SDC and you guys started this PR blast? Why didn't you scream your bug from the rooftop? I'm not saying you guys used SDC as a diversion from your own fucked up code... but I think you guys used SDC as a diversion for your own fucked up code.

Also I tried to be nice but iCEBREAKER you are a little bitch that likes to kick people while they are down and everyone who posted above can eat a dick. And thanks for the money on your uptrend! I was the one buying 500 chunks and dumping them on your peaks!

First and foremost, that code hasn't been implemented yet into the main chain of Monero. Shen specifically asked for testers of the code a few weeks ago so community members could report bugs etc.. Second, this thread was started by a community member, not by a Monero Research Lab member nor a core-team member. Core-team members can't stop community members from opening threads. Also, the reddit posts were mine and I don't have an official "role" as well.

Congratulations on the trading profits.
