Do you have something at size us10.5 to offer? Grin

I sure do buddy! Please reach out to me over PM.

What are your prices for the 350 V1?
What are the 1:1 replicas in terms of sizing compared to the originals?
I am interested in either depending on the prices shipped to the UK.

Thanks

Hi sizing on the 1:1 UA is true to size, however with the V2 Belugas is advisable to go 0.5 size up and that's the same with the copper, green, red and white. Thew new Zebras and Triple Whites are true to size.

Thanks please PM me for more info and pics.

The images look good and you look like a trusted member here. I would like to know the price for both variants and also the shipping details for other countries.

Thanks! Sent you a PM.

Are they easily cleaned? They look dope for sure.

Hi yes they're very easy to clean - https://www.youtube.com/watch?v=drbapip50io

Lots of products to help with protection and cleaning out there.

I'm just testing the waters on interest here for Adidas Yeezy's 350 V1, V2 and 750 range

I have both authentic items obtained from raffles and online bots I also have UA/Unauthorized versions I can ship anywhere via DHL. The UA items are exact 1:1 on the retails using the same primeknit and BASF boost, these are not cheap replicas/fakes.

I'm an established seller on eBay and have buyer testimonials, so if you would rather deal using paypal that option is also available.

Please PM me if you're interested - I can also supply large amounts for bulk buyers.

Here's images of some of the items and buyer feedback: http://imgur.com/a/8AMKi

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.

Bitcointalk threads for any ICO are pure cancer.

Generic idiot on ICO thread example: 

"Why hasn't [insert ICO] launched on [insert preferred exchange] this is a scam I invested my life savings [Insert 2 USD figure amount] it's a failed launch!!! I didn't get my 2000% ROI devs are scammers I will kill myself now"

Every damn time - btw if this is you we could do with the carbon footprint reduction...just sayin.

Picked some up on open ledger - I like this project will consider a large position on this...

Classic head and shoulders trend reversal. I sold, will buy back in at 4k.

Agreed - Unicorn curve also appearing. Be careful can run away as well...

The distribution on this is not great...



39  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BitShares 2.0 on: September 07, 2016, 04:19:37 PM
Just checking bitshares out - worth buying or just go straight into blockpay?

ok - so out the loop anyone have a coherent tl;dr?

I dropped some BTC in the ICO when bonuses were being issued - what's the status are we getting refunded or is this project going to happen?
