Guys. http://blog.anonymousbitcoinbook.com/2014/09/paper-an-analysis-of-darkcoins-blockchain-privacy-via-darksend/

Great read! 

Yeah it left me feeling like CoinJoin is an evolutionary relative of Darksend+. If CoinJoin was Homo Erectus Darksend+ would be Homo Sapiens. You know it evolved from it but into something way better.

Hey Mr About to Troll

Go take a look at the distribution of Darkcoins first:

It turns out that if you take a closer look at the top 300 wallets, you get an interesting picture:

http://bitinfocharts.com/top-100-richest-darkcoin-addresses-1.html

Of all the wallets created in:

*Jan-14: 146,000 DRK
*Feb-14: 175,000 DRK
*Mar-14: 315,300 DRK
*Apr-14: 524,200 DRK
*May-14: 522,500 DRK
*Jun-14: 332,900 DRK
*JUL-14: 96,300 DRK
*Aug-14:713,855 DRK
*Sep-14: 125,624 DRK

Total: 2.94m DRK [~63%]

Well, well. What do we have here?  Some distribution going on and a few whales picking up cheap DRKs.

You really should have hodl your eCash. Instead you gave away your eCash.

edit

before you ask

Another 900k to 1 million coins are held by 900 to 1,000 MNs.

The rest are spread out through 1-2 thousand average me and you wallets.

Nice paper. Kristov did a great job at reviewing the protocol and now it's up to Evan to take it even further, addressing every known weakness, to the degree possible.

I was 100% sure, when I saw Evan saying that he takes darksend peers from 2 to 3 that it was due to the upcoming paper highlighting the issue of almost certain Sybil attack with just 2 peers. The (tx) cost of anonymization makes it easy to both Sybil and bloat. Perhaps it should go up.

We should have had a count down timer.  Can we delete the last few pages of posts?

Overall a positive review. Really liked the level of detail in the paper.

IMO, the next step should be an official response from Evan referencing each of the issues listed in the conclusion and explaining what the plan is to mitigate them. We know that the Sybil attack vector is going to be minimized by moving to 3 peers, but I would like to know about ideas for other improvements.  Especially as it relates to "blinding" masternodes...

People are all tl;dr last few pages.

KRISTOV ATLAS DARKCOIN REVIEW COUNT DOWN TIMER

Someone we will be posting the review on Twitter in 24 hours mins.

"A number of variables must be carefully selected in order to practically limit the size of Darksend+ transactions and “blockchain bloat,” such as the number of Darksend+ peers per round, the number and quantities of denominations, etc. Note that the majority of Darkcoin transactions do not necessarily use Darksend+, such as exchange transactions, mining, mining pool payouts, web services, etc. Considerations for whether Darksend+ is scalable in the future are beyond the intended scope of this document."

Is scalability an issue for us due to potential blockchain bloat? Would have been nice if Kristov had an answer to this. Hopefully Evan does.

Scaling is an issue even for Bitcoin - if transaction numbers spike. DarkSend, especially with multiple round mixing, creates bloat but it can be pruned from the blockchain at a future time.

If DarkSend creates, say, 10x bloat compared to Bitcoin and Darkcoin has 1/10th of the transactions of Bitcoin, it would be around the same in terms of usability. Numbers are out of my a$$ btw.

Electrum and mobile implementation will remove the risks for scaling up.

That's part of the appeal of following the bitcoin codebase.  Full nodes carry the burden of the block chain. Average user can download what they need.

If CoinJoin was a car wash that you traveled to and drove through in order to clean your car, Darksend+ would be a service that washes it in your driveway every night so that you always find the car clean when you’re ready to drive.

Keep in mind this is not pump material. Page 23 is pretty clear on what remains to be fixed. Of course, this is not a zero-proof system, so attack vectors will always exist, but if we can reduce the number, it'd be cool.

Meaning the block chain will NOT be 20 GB to download ?!
That would really help !
I heard from a lot of people in China (who have shit internet) that they have huge problem downloading the BTC wallet (due to the size)
but no problem with DRK Wallet !!
Hope it stays that way !

No Pump,

I'm not surprised Kristov gave it the thumbs up.

Darksend is evolving into an industry standard technology for anonymous blockchains. The implementation of an independent anonymity layer is turning out to be a stroke of genius that stems from Darkcoin's original white paper which aspired to relying on "proven technology" while availing itself of multi-tiered network architecture in which to experiment with best of breed approaches to anonymisation.

Even at this stage, the developers have loads of options open to them because of the 2-tier approach that other blockchains don't support. In addition to that, the client tier can continue to track Bitcoin with respect to retail adoption (which was in the original plan).

The real endorsement of Darkcoin's approach, however, doesn't come from technologists - it comes from markets. In particular, over the last year,
the fact that Bitcoin has not had even a dent knocked in its valuation by the flotilla of competition that's come its way means that Bitcoin technology is going to form THE retail interface of the future. By supporting the Bitcoin native retail interface independently of its anonymity features (provided by the separate masternode tier), Darkcoin has picked up the 2 "live balls" that matter without having to compromise one for the other *:

 - commercial compliance
 - total anonymity and dark technology

It is absolutely not about pumping the material.

However, trolls will be trolls and they don't care about reading any of the details - just spreading FUD around the internet.

Well, in my view this is pretty good and worth saying so.
