Can anyone list the approximate dates to when the coin reward will halve.  Every three weeks.  When was the last halve.

Can anyone list the approximate dates to when the coin reward will halve.  Every three weeks.  When was the last halve.

September 2nd was the last, putting 3 weeks at September 23rd.

How much coins is in block now? 1024 or 512?

Has now halved to 512

For scrypt mining (and scrypt-jane) it takes 65536 hashes to get a share of diff 1. It also takes 65536 shares (diff 1) for every point of difficulty to find a block. This doesn't seem to be the case for QRK. Does anyone know these values for QRK?

That's not entirely right.
IMHO there is a somewhat defacto standard for stratum only, where the diff for scrypt based coins is a 65536 multiply if the original diff which the wallet reports.

So Bitcoin, Litecoin, and so on all require at average for a wallet-diff 1 2^32 hashes (means 65536*65536)
Quarkcoin and quarkcoin clones are "one byte off", means a wallet-diff 1 needs at average 2^24 hashes
Since scrypt is much slower than the sha stuff, scrypt based coins started with a much lower difficulty (i think 256*128 times lower) than bitcoin based ones.
I don't know if stratum at first only supported integer diffs and not the needed 0.00xxx diffs, or whatever the reason was, somehow on stratum the coins diff (as reported by the wallet) is multiplied by 65536.

As said for Quark: Diff 1 is 2^24. Stratum shouldn't modify this value. At least i didn't code any reversing of stratum diff in the minerd.

(If i did write garbage, please correct me)

Sounds like someone switched off a botnet (or his boss found out). The hashrate on the few p2pools I checked, including mine, is rather stable. Also, was the diff really above 950? I don't look for the diff often, didn't notice that.

Also we have some mainly 1:1 clones using the quark hashing algorithm

some good news for qrk

I want to eat that. Can't someone make quark candy? And for every bag of quarks you buy, you get some coins. And of course you eventually get enough coins to buy more quarks with it, or other goods/services. Let's get it into Walmart.

hope he is definetely gone. He made a lot of bad things to quarkcoin and community.

Did some benchmarks of the sse4 miner (just took this version https://bitcointalk.org/index.php?topic=260031.msg3047868#msg3047868) on a bunch of Intel Core2 Duo and Ivy bridge, and here comes the great equation.

The hashrate is a linear frequency function (what a rocket science). For quark algo just divide frequency by 27.5 for no HT, or by 40 for HT to estimate Khashes PER THREAD. If you run less threads than CPUs on HT, the number is somewhere in between. E.g. for 3 threads on 4-thread CPU or 6 threads on 8-thread CPU it is ~35, see https://bitcointalk.org/index.php?topic=260031.msg3076346#msg3076346. It would be nice if various CPU owners will try the formula and prove or disprove it.

I do not have any AMDs at hand, but it seems they follow "no HT" path for ALL cores (https://bitcointalk.org/index.php?topic=260031.msg3021817#msg3021817). Thus, high-frequency AMD FXs are winners in terms of kh per CPU. I am getting 780kh on i7 3770k at 4GHz with HT (8 * 98), while FX 8350 gives 1100kh at 4 GHz (8 * 140). Here power consumption comes into play. For Intel it is ~8kh/watt for IB and ~2kh/watt or less for C2D. Can anyone provide wattage for AMDs (real-world numbers, not from online benchmarks)? Sandy Bridge and Haswell numbers would be usefull as well. Lets make quark hardware comparision table  

I have an AMD Sempron 145 Sargas 2.8GHz (single core) w/ "core unlocked" and overclocked a bit (with that motherboard's "OC Genie") that gets about 220khash..  my i7-960 (it's not overclocked, but I have turbomode enabled, so it does that automatically, goes to 3.35ghash or so) can get about 600-620khash/s tops..  i7-4770k is 1mhash+, but well, it costs a lot more than what you'd need for equivalent from AMD CPU

oh, *intel e6850 gets around 200khash w/o overclocking

err, never got around to this

had an emergency visit to the hospital to get my gall bladder removed 

i haven't read posts after this yet, so if nothing is still there, i'll try it this weekend

Very helpful, thank you!

almost perfect exchange unfotunately so far it is missing one quite important ingredience..... there is no volume.....
and without volume it is quite a problem....
but I must admit that it is well done but they should offer something to attract people and liquidity, I tried to bought several coins but of course so far without success. And I am thinking of sending my funds away....
In this initial period they should offer eg trading of new coins which are not possible to trade anywhere else or low fees or some special news for cryptocoin community otherwise I dont know why I should put my money and enable them liquidity with my funds....

Agree 100 %. The pathetic trade volume is a serious problem. Also, the difficulty has halved over the past 24 hours. In other words, the support from both miners and traders is decreasing fast. Those are very bad signs for the future of Quarkcoin.

the trade volume where?  it gets plenty of volume on crypsty,

that new exchange has pathetic trade volume, yes

I was overwhelmed by the amount of logo on the quarkcoin web site.  Nearly had a stroke.  We need someone with talent to take over the website.

Other than the wallet logos I think it looks fine. But there's nothing there.. every link in the menu leads to a 404.

blame the idiots dumping coins like this for the latest shitcoin..
cryptsy has been showing a steady decline in QRK from 300 to 175 last i checked and i holding mine and have bought more occasionally
even though i can't mine this coin anymore since two halves ago roughly
once again the crowd roars in and makes it nearly impossible for me to get anything at all mining
and they don't care.. pump and dump and leave the corpse and bag holders in their wake.

getting to the point where i may have to just join em.. i see no choice
why have integrity or look at these coins as anything more than an opportunity to scam and weazle and flash-premine and ponzi scheme your way to the top
why support ANY coin ?
we might as well just dump the hell out of the coin on exchange day one after we pre-flashed mined the hell out of it
and then move on to the next childish retarded gimmick scamcoin.

i think i'm going to consider dumping my quark and moving on, there is no point in trying to compete in the market with sleaze bags
fuck it might as well join em :/
and yeah i'm serious too

Instead of dumping them, I would like to contribute to the community by setting up a bounty for website/game developers. I am going to do it perhaps this weekend when I have free time.
Please don't be too serious, altcoins are for fun, don't take it so seriously - you can't make a living with altcoins!

i bought like 1.5 bitcoins worth at 200-210 just for shits, maybe some more later.

i guess i sort of consider it 'play money', seeing as how i don't see myself mining bitcoins ever again... well, or even using them, except for this altcoin shenaniganry.   not some huge sum anyway, like a handful or two

(ed: cause I don't see much point in making $$ for ASIC manufacturers, scratch)

Is QaUvy4dK1rycXtpzmTKuVUFfu7sSVQ8xKb an actual pool?

I guess Quarkcoins is susceptible to botnets + I've been thinking maybe there's someone mining off of GPUs or something =p

who the hell told you that ?

your the problem with that attitude.

The most honest coin will be a 100% premine.  Imagine if some leader a true leader just donated them all away.  All the websites, block explorers, exchanges, and more website would have them and not the ffin miners.  The experience miners know all the tricks to block your ip botnet, cpu asic.  Why not just have a proof of stake coin 100% premine.  Then every exchange will make the coin more valuable.

I blame it on Cryptsy's Autosell feature.  It has caused the coins to go in the shitter cause nobody can actually pump up a coin and keep it up.  You pump it, next day it is either back down to same level you started at or lower.  The autosell is Cryptsy's way to get more fees.
