LOL SDC getting salty about cloning but will gleefully steal code!

Great idea

Shen providing a review would be great for Eclipse.

I was getting the opinion of others on SDC/Eclipse and a good point was brought up.

any input or thoughts from the XMR camp? Does this mean Eclipse is cryptograhically anonymous?

They seem to have at least tried to fix the one identified flaw in SDC. Whether SDC has other flaws they didn't fix or whether their fix is even correct is not something anyone can answer without spending a lot of time reviewing it all, which probably won't ever happen.

Valid points, I am hoping they will be able to get their 'fix' properly reviewed.
Assuming the fix is indeed correct, would that mean that it is then truly anonymous?
In other words: if recently exposed flaw in SDC anonymity was fixed, does it make SDC as/more anonymous as XMR? or is SDC still inferior to XMR for anonymity?

What about the other 99.999% of SDC, developed by the same people who made a basic math/crypto error, and which no one has ever reviewed?

Shen found that one flaw effectively by accident, while working on something else.

If SDC were comprehensively reviewed, then one could make claims about it. At this point, I would not.

Have you considered the possibility of this? Is there a reason why you chose shadowcash method of anonymity over other ways of anonymity?  

As usual, smooth has beautiful insight, but it's not an insight that wasn't also obvious to us.

It's important to understand that SDC ported the cryptonote ring signature system to the bitcoin codebase, almost in it's entirety. You can see what I mean in the naming of the methods:

CN: hash_to_ec --> SDC: hashToEC
CN: generate_key_image --> SDC: generateKeyImage
CN: generate_ring_signature --> SDC: generateRingSignature

Why is this important? Because where SDC has an opportunity to deviate, they may create security flaws. Here, they chose to use curve secp256k1, which has a number of useful properties, most notably the potential for an very efficient implementation, as has been created by bitcoin. In choosing secp256k1, they had no template function by which to map a scalar hash (SHA256d) to an EC point. So they did the most "obvious" and provably wrong thing, they took the scalar multiple of the EC base point, using the hash as the scalar.

Shen discovered this flaw, we absolutely do not want to take credit for his insight.

In general, SDC did not deviate significantly from cryptonote elsewhere from what we can tell. Thus, since they followed the cryptonote recipe, the rest of the ring signature system will be as secure as cryptonote for the simple reason that there are not many ways to screw it up. Once you have the EC point from the hash, generating the signature and key image is identical to the cryptonote method.

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:

https://github.com/shadowproject/shadow/commit/106afc6975cf41090ca2a0c47877de0cc8a16f1a

SDC ended up using the EC teams suggested fix without even crediting the dev lol.

  Tell me do you know what TOR is? If you do not want long technical explanations,
Just think this: all these people use TOR and can not be wrong.

Follow this link to see who are using TOR ...

https://www.torproject.org/about/torusers.html.en

TOR is the most effective way to preserve privacy.

Remember this:
Spectrecoin adds, uses the most advanced "classical methods",
more, it always works, using the TOR network.

......My intent here is to legitimise (sp) this developer, community and project. It only ever has been with any other project thread i have entered and challenged....

Who are you to challenge this project or any other for that matter? Someone appoint you the BCT forum police?
This only seems to most of us ..... to be the actions of a SDC fan trying to stir up FUD.
That is  self serving to feed your ego and has no place here.
Your actions are of a total troll.
You are dismissed.

[faxxer]

Just add to ignore list, focus on new features Mandica, just bought more because of the price is going down.

[Gandalf86]

Pls announce the ICO result in the thread and official web site, it helps this coin to make forward.
How much bitcoins did you receive by ICO? How many accounts join in ICO? Could you explain this?

The problem with the ICO result is that it is pretty disappointing, so it's bad advertisement for the project.  

IIRC they were something like 16.5 BTC were raised, and the total supply (pre-POS) of 20.000.000 was distributed, which makes a price of 83 SAT. Now when people read this and see that the current price is 2000 SAT they may think it's extremely overvalued already. But the truth is, Spectre started at a market cap of 15k USD, which was extremely undervalued, and now has a market cap of 360k USD, and may go up to 1+ Mio. easily in the future.

@Gandalf86 quite simply put, when you have a ICO funds key and or a premine then yes! My intent here is to legitimise this developer, community and project. It only ever has been with any other project thread i have entered and challenged. The disturbing thing is that the developers and community in those threads delegitimised it for themselves in that process. I see the same happening here.

Calm down, take a breath and look at what i have actually asked. Its not near as hard as you are trying to make it out to be.

@LAS:thanks for your honest intent to save our community but we don't need you at all.
Instead of wasting time in elaborating on any justifications to you, devs put all time and energy in coding outstanding products like the mobile platform. That's their choice to deliver.

[Beachguy]

@Gandalf - Yep,you are so right ... XSPEC snuck up on alot of people....I guess busy in the holidays and all. Since the distribution the Devs have consistently delivered and are about to deliver again with the Spectre.Cash
android app.

"Spectre.cash is an Android app which will be able to act as a XSPEC node(*) and the functioning of the app can be thought of in three layers that come together to create the ability to process anonymous cash transfers. This can happen on a purely peer-to-peer basis and no server and no central database or register is needed."
-from the XPECT webpage.

Valuation at the distribution is of little matter , the important thing is where XPECT is going.

If folks would read...and I mean really read over the  the SpectreCoin webpage https://spectreproject.io/  (and it takes a little time to digest).....they would see this isn't a 2000 to 4000 sat coin. The devs didn't spend $$$ to have a fancy web page that tries to dazzle people either. They're working on the important things.

With its low coin circulation (only 20,000,000 at the ICO w/ 1,000,000 going to devs)....its more like a 100,000 to 200,000 sat  coin (.92 to 1.83 us at today's btc) to fulfill its goals.

over 240,000 XSPEC is available on C-Cex, Nova and Cryptopia....(of course, like most exchanges, some are at stupid price), but there plenty to be had at reasonable prices that will pale in comparison to where its going.

Coin with 20 000 000 suply can easy reach 10 cents per coin. It's sure that all depended from development. I'm in

@Soulgate - Good to hear, nice to see another coin developer appreciate XSPEC!
btw I mine Virta!

Spectre.Cash / Spectre.Wallet update

We have completed the first stage of building a Spectrecoin Android wallet and will be releasing the beta in the next few days.
This is a full wallet, i.e. it connects through Tor and has all the anonymity features of the desktop wallet but with a simple user interface.
Staking has been disabled in the Android version but may come as an option if there is any need for this.



This is the first stage of the process to develop the full Spectre.Cash app. Once we have released the Spectre.Wallet beta and we get some feedback we can start work on the more advanced functions of the Spectre.Cash app.
Further details on release of the beta Spectre.Wallet for Android.

Livecoin
XSPEC will launch on Livecoin.net this week. Livecoin is currently setting up the wallet and testing. I will announce here and on the Slack channel as soon as we listed and ready for trade.

[Shadow_Man]

Looking sharp.  I'll volunteer to test the android app.

There you go!  

The funny thing is, some fool dumped his XSPEC down to 0.00001000 just today. I'm sure he will regret it very soon.  

Great job @ Spectre team!

This ico address:
https://blockchain.info/address/1SPECTREYpMssJrVpHqi375DfNm7LxkZ2

And the pattern of funds transfer that followed the last deposit into that address are sketchy as anything. (by sketchy i mean i cannot yet, find documentation regarding distribution of ico funds)

https://blockchain.info/address/1CAVx4q5Cghiqrx4kjuKiqq3iNZ5GKwscM

Would anyone not completely naive and reckless like to speculate with me what happened here? Follow the money and see what you think, because its simple deduction not rocket science.

Am i missing the document url to see whats happening with the ico funds in real time? Is there one? If not why not? Will you start one?

[goopuss]

Look Ape, Go home. How many times do I have to tell you? Nobody cares what you have to say.

So now you're starting another bunch of accusations....just stop already, you're only making yourself
look even more of a troll.

[malcovixeffect]

Where is this being traded?
Whats the current price?
Ill might throw some cents cos its cheap..

This is valid please add more accusations.. I still thinks the price is high for me.

[goopuss]

Mandica, you have delivered everytime, on time. Whatever you are doing with the ICO funds is working. I am happy with where the Spectreproject is right now. I think many or even All Spectre investors are happy and do not need to see any ICO fund documents. Just keep doing what you and the team are doing. I can't wait for the world to realize Spectrecoin. I hope the dome will be open because it's going to blow the roof off! Great Job Team!

[malcovixeffect]

Im waiting at 500sats.
