[SDC] ShadowCash Uncensored: Zeuner, Zero Knowledge, Zero Trust. What Happened?

[Bank_sy]

It looks like SDC went live with our solution for hashToEC.




They switched from creating a new generator, discussed here: https://bitcointalk.org/index.php?topic=1378922.msg14079014#msg14079014

What's this mean?

We are the leaders kids.


This is the heart of our algo, pushed publicly 9 days ago:

Code:

    for (j = 0; j < k; ++j)
    {
        if (j == 0)
            x = u;
        else
        {
            secp256k1_fe_set_int(&i, j);
            secp256k1_fe_add(&x, &i);
        }
        if (secp256k1_ge_set_xquad_var(&Q, &x))
        {
            success = 1;
            break;
        }
    }

This is shadowcash's pushed to their repo 3 days ago:

Code:

        while(!EC_POINT_set_compressed_coordinates_GFp(ecGrp, ptRet, bnTmp, 0, bnCtx) && count < 100)
        {
            count += 1;

            if (count == 100)
                return errorN(1, "%s: Failed to find a valid point for public key.", __func__);

            BN_add(bnTmp, bnTmp, bnOne);
        }

This is their commit after they read our critique of their method:

SDC used fix that EC came up with first

[bangomatic]

yeah but eclipse cloned shadows complete code base...so...its a shitcoin clone.

LISK!!! on that we can agree. Looking forward to launch.

[BrosephGordonLevitt]

I can't believe I read all 18 pages of this ridiculous thread. 

Some people...haha.

Anyways glad to see everything's running smoothly, was keeping up with this project a while ago, nice new release and looking forward to the others. 

I don't think threads like these deserve a quarter of the response they pulled, diverts the attention from more important things for a developing coin

Pff†…

But you did read it, right? What in particular do you disagree with btw? What is "ridiculous" about it?

Im intrigued by the SDC "Phoenix" resurrection attempt, but the question is will people trust the anon is working after Shen deanon'd the whole chain? Sure you have a fix, but will you need another? Has Shen performed a full review of the anon now? I think people would be interested to know that. And what of Shadowchat's security?

[child_harold]

Great to see some more recognition from a respected publication. This is big.

Yeah about that…

How exactly did ryno end up getting quoted in that article?
http://www.sciencemag.org/news/2016/03/why-criminals-cant-hide-behind-bitcoin
The journalist was aware of the recent deanonymization, right?

Why don't you just ask him?

[child_harold]

Why don't you just ask him?

Hi rusty,

Geez - I think that boat sailed…
Why dont you?

PS Im happy for you the price spiked up a little as a result. At least you can recoup some BTC, whatever the outcome.

Hey mate,

Well you tried to sink the ship but she appears to be well afloat. 

Hop back on board anytime and I will help make you feel back at home.

Serious answer, cryptonote level anonymity on bitcoin codebase.

To be fair I got a lot of help
Its not s though I wrote those whitepapers, didnt deliver the peer review or de-anon'd the entire chain
(or wrote a blogpost entitled ShadowCash Deanonymized? Nope, roughly 24 hours before it totally was)

All I did was write about it, and in this thread cause yours is heavily modded.

How much has Shen helped you guys out to fix the problem?

[rustynailer]

Shen did a fantastic job helping out this open source project.   

[child_harold]

Shen did a fantastic job helping out this open source project.  

That goes without saying. It was broken.

But what of the future?
You have no cryptographer since Tecnovert left.
And the bitmessage implementation (shadowchat) has not been vetted…

Is ShadowSend now fully peer-reviewed and secure post-Shen? Or could there be other exploits?

How will you regain trust?

If Monero had been deanonymized the way ShadowCash has been it never would have recovered.

Is this true?

Shen did a fantastic job helping out this open source project.   

Did Shen fix the bug? Did he go on to do a full review?

[sickandtired]

Delete and shut down any comment or info that they dont like about SDC from the official FORUM thread and claim that it is just an info thread and not a forum (bit insane, authoritarian and against everything that Opensource represents, but still claim to be opensource) --- Checked.
Worst distribution (coins in few hands) --- Checked
Pump n Dump --- Checked
Broken Anon (after being used to hype the first pump) --- Checked
New Hype for new Pump and Dump phase --- Checked

Pump and dump much vaporware?

ETA of the marketplace?

2016

Merry Christmas everyone or however you wish to celebrate it
Personally i will be celebrating the birth of Jesus.

or 2027? why 2016? Is your Jesus late?

2 Real Decentralized marketplaces are now out and available for the public (one of them with a proper Alpha testing (not inside only testing like sdc) Now what is your motive to hold aside of the fact of being the big holders of the 50-60% of the coin, with that Group power, and non transparency, and now the real marketplaces coming out, this is aiming to become a huge failure, always delays and keep moving the date out every time just playing the market to make it dump so you can continue to hoard an 70-80% of the coin instead to play your pump and dump.

It was de-ringed, not "broken". It's an open source project so anyone can work on it (including smooth, since he pays so much attention to the project). WTF kind of vetting should SDC get, the fucking Elders of the Internet to stamp it with their dicks?

Of course there could be other exploits you fucking troglodyte. IT'S FUCKING 1's and 0's! It's goddamn code. Not like you understand anything about any of it though.

Regaining trust will most likely be done by demonstrating the coin's technological advantages over other coins (some coins don't even have a wallet let alone the Elders of the Internet dick stamp).

Why would a coin not recover as long as it is still being developed with a beneficial end game for all of humanity in it's crosshairs? YOU FUCKING TROGLODYTE

*Edit* My favorite part about this whole read is that you complain about the fairlaunch distribution yet are currently invested in an ICO!! rofl

[Gillette]

SDC is a good coin backed with constant development.

So this is the graveyard for deleted posts now? Fair:

… and am happy to see you have chosen bitmessage channels…

bitmessage=shadowchat
channels=clone

This message will (most probably) be deleted
but hopefully not before you read it.

Welcome

CH

To be clear:

An unapologetically wholesale rip-off of other men's work (as shadowchat is to bitmessage)


Some friendly advice:

1. Rewrite the whitepapers for ShadowSend and ShadowChat
2. Get peer reviews.
3. Start testing publicly.
