is darkwallet running already? i thought its just a project.

And what is the difference between Darkcoin and DarkWallet's Coinjoin implementation?

I’ve heard some chatter and misconceptions about the difference between Darkcoin vs Zerocoin, so here’s a write up about the pros and cons of each approach and what they do differently.

Darkcoin

First off, most people start by asking is DarkSend actually real and does it work? Yes! Checkout the development progress here: https://bitcointalksearch.org/topic/anndrk-darkcoin-darksend-anonymous-technology-pre-alpha-launch-467857

DarkSend is based off of Greg Maxwells original idea called Coinjoin, with some added improvements and decentralization. The decentralized approach is important because the logic is self contained in the client, which is managed by the users themselves. This is a trustless solution.

Darkcoin uses the base transaction layer to sign it’s transactions in much the same way that Bitcoin does. The mathematics are tried and true and have been used for years in computer security and banking.

Transactions will be grouped together and the same cost as sending transactions on the normal network. Both DarkSend and normal transactions will be available to choose from, but at some point we might default to DarkSend (and go Dark).

It’s also worth noting that this approach doesn’t bloat the blockchain at all either. Transactions are the same size as the would have been.

Zerocoin

The approach Zerocoin takes is to use some exotic mathematics to hide the identity with a zero-knowledge proof. This allows a higher quality of anonymity, but also could have some unforeseen hole that will be exploited later.

Checkout this link to see the mathematics I'm talking about: https://github.com/Zerocoin/libzerocoin/blob/master/AccumulatorProofOfKnowledge.cpp

Zerocoin's proof of work is in the 344 byte range, which was reduced from 50kb in Mathew Green’s original work. These proofs must be stored in the blockchain for each transaction that goes through the network for confirmation purposes and the ledger history, so this will cause a lot of bloat. There is also a need for these proofs to be processed by the networks nodes, being larger will cause more intense CPU usage with smaller transaction rates.  

Mixing Services - (Fedoracoin, Anoncoin)

The revolutionary feature of Bitcoin was not the currency, but the decentralized ledger. Mixing services are great at what they do, but any hosted service is inherently centralized and requires an amount of trust of that entity. Services setup in a centralized way can also be compromised without users knowledge.

---

I think the Darkcoin approach has the best mix of features, with the least risk and it’s decentralized. So we definitely have our place in the market.

EDIT: I accidentally copied misinformation from a bad source on the internet, I was looking for original sources this morning trying to vet my post and found it was wrong. Sorry!

Just find that this one lacks one bit. Apply also to onetime's version.

Edit. You got it first Speedie.

So right now this is about the same profitability as Max?  Is C-Cex the largest exchange?  I don't see much volume there. 

I like it too. The binary word at approximately 8 o' clock is malformed though (7 digits not 8). Maybe this would be better:

01100100 01100001 01110010 01101011 01100011 01101111 01101001 01101110

THIS is the news, as much as I like logo design talk.  THIS is what's getting me excited!  Great work!!

Yes it's really nice.

Only small thing with the 00110 : pixelized? aliased?

This is my fav so far, I like the clean / polish of it, and the dark blue. Nice touch with the blured seperation.  Thanks to all who are helping this coin!

this isn't good enough.. I'll improve it later. the top font looks unprofessional.



-onetime

I'm sure we'll get the Max bump soon enough

I wasted 6 hours mining maxcoin, max keiser needs an ass kicking.

I love this coin. It was released on my birthday and I've always been a dark-side kinda guy. I'm in it for the long haul

Not so strange. Myself I've been getting almost no new coins at all with the recent difficulty and moved all cpu's to RieCoin instead. I might consider moving gpu's to DRK if MAX continues to drop though..

Everyone is mining the new dumpcoin

I'm happy it dropped 

More coins for me to mine !!

much like dark matter idea! nice...

Expect one hell of a jump after alpha tests tonight  

I literally spend 10 minutes making this just thought it would be funny. Mich be a neat idea for the back of the physical coin!

Network hash rate dropped quite a bit
