Do we have an Official "Darkcoin accepted here" banner? If not we may need one soon, Please post imgur links here or the DRK subreddit!

This is the only one available, I think

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



-onetime

That isn't too bad, I know we have some graphic talent here. Let's get the ball rolling as I'm starting to advertise for us and we will need a proper "Accepted here" banner for merchants!

Also everyone don't forget to vote on mintpal to add DRK, and retweet my posts that concern Darkcoin. People are noticing us but with our great devs rolling out these big features soon it should catch on very nicely. https://twitter.com/Kreative_Crypto/status/436486080355770368 RETWEET!

Wow current diff is 408

Multipool or a large farm must have jumped on it... that means they'll try to dump mined coins - they rarely hold...

Possibly a large farm, multipools are usually strictly basic scrypt only.

They didn't seem to stay around basically after that diff spike. Diff now 169.

I don't care how corny it is, my new Darkcoin chant will be henceforth "To the dark side of the moon!!!"

Hehe, love it.

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://bitcointalk.org/index.php?topic=467857.0

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 2kb range, which was reduced from 1024kb 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. 

The spec for Zerocoin also requires a 100% premine. I believe mining is what gives cryptocurrency their base value, so this could be a problem for the currency in the long haul.

With the high CPU usage, how will the network deal with DDOS attacks? I could send bad proofs that must be processed. It’s much harder with the Bitcoin protocol because the math is pretty fast and you would be banned quickly.

Imagine if Zerocoin had to deal with 20 transactions a minute, that would be 58.98MB/day that will be added to the blockchain. After a year, that would add up to 21.5GB. Now god forbid you have to reindex this, you’ll have to process all of the proofs on your computer? That might take another year to complete.

---

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.

I'm requoting this because everyone needs to read it!

Thanks!  Thats a great explanation of the differences between zerocoin and darkcoin.  Could you also compare the mixing service vs darksend?

I updated the post to explain that, https://bitcointalk.org/index.php?topic=421615.msg5241291#msg5241291

DRK should be use to SAVE our world and needed children. A charity fund should be created

Been watching this thread for a long while - have my share of DRK - am excited.

Wanted to add some positive comments - I feel that the community here is really starting to build up all the pieces necessary to make this a success.
As we all know - it's not just the coin's tech - the tech behind it will give it its long term value - but it's the rest of the community that will support its development and give it value in the short term.

I myself have a good computer science and security background - but remember - most people won't understand what is under the hood at all - so the community needs to present this information in an easy to obtain and understand manner - so that the community can grow beyond just people who understand the tech behind the coin (not that it hasn't - but I'm talking long term growth and full adoption here - most people won't understand - but in the long term we want them to use the coin).

There have been some good developments in that area lately - ex. the posting to the main page about the key differences between Darkcoin and Zerocoin - and I think we need to be aware and continue to do things like this to improve the experience for newer users/adopters.

Absolutely LOVING this!! ****ing awesome. 

It's dark, professional and classy.

Yeah these are definetly more professional keep em coming! Great stuff!

[Speedie]

Holy difficulty batman! Even if everyone was using the improved GPU miner, which is giving me roughly 3x DRK hash rate versus regular Scrypt mining, the network is now 1.5GH/s Scrypt equivalent. And they're not, so it's more than that.

Also want to say thank-you to eduffield, it's a real pleasure to see a coin with legitimate innovation and a committed developer amongst all the copy/paste trash out there. Excited to be a part of this even if it's "just" as a miner.

Progress Report #6

Thanks to everyone that showed up last night to help out with the alpha test! We had a great showing of about 30 people and a full chatroom at #darkcoin-test. After 3 full hours of darksending money randomly around, we ended up doing over 100 darksent transactions!

It worked fantastic, so next I'll be moving on to fixing some of the last known issues, then on to the next milestones.

Looking forward to the next test. Thanks everyone
