Guys
Today few of qrk.coinmine.pl miners found an exploit to cash out more coins that they actually mined and hot wallet was completely dry out. This exploit was possible because of site upgrade I was doing and its not related to pool software.
I know this was kind of my fault but I am kindly asking honest users to give back Quarks to this address: QY9f1fRFMv3xJha9XH637k2Yey1WSkvGBA
Will appreciate your cooperation.

How much did they get? If a lot those people cashing out would explain the drop in price earlier.
approx 20000
It's pretty mean to rob a pool. I can't imagine the alt pools make a fortune.
I have about 15 cores pointed at qrk.coinmine.pl - very good stable pool.
I hope you get your qrks back.
For all you old timers, what was Quark's initial Difficulty?
This page has a chart of Quark historical difficulty at the bottom: http://www.cryptocoincharts.info/v2/coins/show/qrk
Wow, difficulty started much higher than I remember. 84
Just step by from curiousity but as i see quarkers have the same hold strategy as RonPaulCoiners so i need to look at it with bigger respect now and look closer at it.

I think most people use Cryptsy... Bter looks good, but you have to first sell you BTC to CNY...

Edit: I forgot to pay fee, it is gonna take ages, omg :/
Hello. First of all, thanks for your donation.
Second, how much should the fee be so as the transaction is quickly processed? It seems none of the transactions produced by my faucet are receiving any confirmations. I'm paying a 0.0001 QRK transaction fee on all of them.
Also, a question for everybody: does Quark's blockchain accept transactions only over a certain amount (like DOGE's, which only accepts >=0.01 DOGE transactions)?
Just step by from curiousity but as i see quarkers have the same hold strategy as RonPaulCoiners so i need to look at it with bigger respect now and look closer at it.

How hard would be to implement POS in Quark? and what would be (if any) the disadvantages?
fucking hard. Everyone would have to update their client at the same time, especially miners. Is their already a CPU-Coin with POS? The disadvantage is, that it would be always some kind of inflation, In Peercoin theier is a counter mechanism. The fee goes not to a miner but get destroyed. So you have deflation there.

Wow! I always wondered, why there is such a big community but such a shitty site... (but look at PPcoin. Their site is mostly offline...) Sent you some

So after reading about the potential 51% attack on bitcoin. It's good to know quark is more secure because of CPU mining. I think people will finally understand how quarks actually stand out and why our mining period was so rapid.
Quark CPU mining insure that each individual able to securely defend the network and protect it.

I'm not sure that is completely true. The problem with Bitcoin and a 51% attack is more about the pools than about ASIC's, though there is something of a potentially centralized problem with ASIC's, yes.
Who has more mining pools, Bitcoin or Quark? I am pretty sure BTC has MANY MANY more pools. So, what that means is, due to Quark having fewer pools, it is even more important to watch for a 51%
attack. You can have good people unknowingly mining in a bad pool - with no idea of the pools intention. I think the Gigahash.io double spend thing is exactly that.
I would suggest some form of protocol for pools to follow that doesn't allow 1 to have more than 25% or some smaller arbitrary amount. A large holder of ASIC's (or CPU's) could still control a few pools in the same way though, so we need to work on this. For sure a single point of failure.
I am a holder of both Quark and BTC, with the latter being much larger than the former. But I have to be honest here, the best Crypto's should win as this is about the people, not the money (per say.)
I mean that as a solo miner. Average people are able to start mining without specialized hardware like ASIC if a pool starts to get close to 51%. While bitcoiners have no power unless they own ASIC hardware to help the network. This is where quark beauty shines.
I don't know. A pool consists of many individual miners. Therefore they can switch or make the pool even with 50%+ act with the protocol.
Well, if I want to support the network ASICs would be nice, true. But this is not only a disadvantage of Bitcoin. How many computers do I(or one entity) need to infect to get 51%. And with Quarkcoin?
I'm pro Quark, but just thinking about weaknesses in any of the coins I hold is a good practice. A weakness of CPU's are bots. If a competing coin saw Quarks as a threat, what is to stop a fairly wealthy individual from buying some mining bots on Quark (huge amount) and try to get control of the network via a pool then? Not sure how expensive it would be on Quark but stranger things have happened when money is the goal, unfortunately.
Not that I think this would happen, but its good to be ready in the future for any form of attack.
The cost of the attack is not really an issue. Botnets are installed via malware and infect hundreds or thousands or millions of computers. An attacker only needs the will and technical means. Money has nothing to do with it. That is the danger of CPU-only coins.
Botnets are getting much harder to install on peoples pc these days. Everyone i know if freaky anal about antivirus, malwarebytes etc etc, windows is getting pretty secure compared to what it used to be. People running old shit like xp probably don't have their pc on much and the cpu is mostly crap and they will notice if their cycles suddenly get raped. I would guess botnets will be less of a threat in the future. However, would be nice to see QRK have some POS later
just a couple of percent for anti inflation and protection against 51% also..

Thats a good point, Quark is not a POS coin so i assume it can get 51% attacked? wonder how many cloud servers it would take if it can be attacked.. especially after the block reward flattens out!
