the most I can do is 675 kh/s on i7 4770k cpu with minerd-core-avx-I
try -t 8 in the cmd line... |
|
|
|
is haswell , ivybridge and sandybridge use same or not? I use minerd-core-avx-I.
is that correct?
Try the various files (especially those with aes+avx) and see what gives you the best performance. |

how do I setup i4770k to be at least 800 kh/s?
There isn't really a lot of customizing for CPU mining when compared to GPU mining. Make sure that you use the 1.3 miner (available here http://wiki.darkcoin.fr/index.php?title=Installer_Minage_CPU_Windows assuming you're on Windows) for improved AVX/AES implementation and a performance bump. Other than that just pick a pool and turn on the miner as you would for any other coin. /\/\ What he said plus use -march=native and -O3 if you are compiling the miner in linux. Other than that, if you are aiming for most kh/s, clock the hell out of the cpu and use all threads. However this might not be the best solution in terms of power efficiency. Usually the most power effective way is to use standard clocks or slightly higher clocks but with lower voltages, even if one loses khashes. If the watts go, say, from 70 to 100 just to get a +10%, it's not worth the difference. + what HammerHedd said just now. |

is there a profit calculator for this coin or not? can I be use cpu for this coin or not?
No profit calculator but the data are as follows: Profit is approximately 1 DRK per megahash, give or take. GPU megahashes right now are 3X scrypt ones. Which means if you have 1 Mhash in scrypt you have ~3 Mhash in Darkcoin = ~3 DRK per day. CPU mining is possible. Top CPUs like i7's overclocked at ~4.5 GHs report close to 900khash with the 1.3 AES/AVX miner (which is around the hashrate of a mid-level GPU of the 58xx and 68xx series). |

VTC RIGHT AFTER BTC & LTC IN VOLUME ON COINMARKETCAP.COM!!!!1 Bitcoin $ 7,099,236,235 $ 565.76 12,548,050 BTC $ 17,346,048 -0.91 %
3 Litecoin $ 421,271,393 $ 15.71 26,814,854 LTC $ 6,325,487 +0.57 %
16 Vertcoin $ 5,130,116 $ 1.82 2,814,850 VTC $ 884,099 +30.42 %
but obviously you guys don't know how to hold! Total marketcap $5M, traded $0.8M! Shame on you!  Thing is, the higher the price is, the more unsustainable the price becomes. As the inflationary curve requires ~56k USD per day just to sustain the price (28800 coins per day X 2$ per coin) one month of mining requires a capital inflow of 1.7 million USD - just to keep the price steady. And with Vert becoming a mining attraction through coinwarz, it's a double edged sword: On one hand Vert gains publicity on the other hand it also "gains" a lot of mine&dumpers. It's a difficult situation to balance and holders know that the chart/price spikes are more risky to hold. |

Ok, so I was a bit bored and instead of idling on reddit and looking up coinmarketcap every 2 minutes, I tried something. It's just a rough copy where I copied most of the /r/DRKcoin and just used a different stylesheet which was already a almost complete layout. I think the header could be better, but aside from that, I think it's much more user friendly than the current scheme especially since a new, brighter website is about to launch https://i.imgur.com/LbGy1gX.pngWhat do you think? Nice... I got a bit bored myself too and changed the 2 files (tray icon / splashscreen): The result was this (somewhat crappy quality due to the animated gif): http://oi61.tinypic.com/6gltl2.jpgIf you want to compile it in your own client, the files are in /src/qt/res/images * and /src/qt/res/icons ** * http://s17.postimg.org/6d10zr2rj/splash.png** http://s4.postimg.org/8xj2wfvl5/toolbar.pngI'm no graphics expert so it's quite simplistic really. Black + darkcoin logo. Seems kind'a elegant though  |

It has however other types of uncertainties like what will happen to gold production if the energy prices are somehow down by 80-90% Wouldn't less Gold production create more scarcity witch would make the gold even more valuable? Yes in the hypothetical scenario of lower energy prices that translates to more gold production. That's actually more of a chemical reaction rather than a transmutation of elements, like we have in fission or fusion. But Gold and Silver are ALWAYS better than paper money. Paper money = scam. |

I'm having a strange issue.. one machine (ubuntu) refuses to update it's wallet. I've deleted literally everything (the darkcoin/ directory and the .darkcoin/ directory) and rebuilt it. As before, it hung on s bunch of orphan blocks from about 6 days ago. So, I deleted and rebuilt everything again, then took everything in the .darkcoin/ directory from a currently working wallet (except wallet.dat) and copied it into the new directory so it would (theoretically) have a decent blockchain to start from and only be a block behind. It found one block, and then stopped communicating with the blockchain. I can post the debug log if someone wants to help. It has completely screwed my Saturday  I was hoping to have a nice smooth p2pool transition Are you running 0.9 wallet? |

I know this is not the orthodox solution, but you can try this:
1. Make a script that runs sgminer repeatedly
2. On another window, run: while [ 1 ]; do killall sgminer; sleep 600; done
The first script will make sure sgminer is started and running time over time.
The second command / script will make sure that sgminer is killed every 10 minutes (600 secs)
When it is killed, the first script will restart it.

i.e. if we reach x5 the amount of hash required for producing a new block every 2.5min (with a reward of 5 DRK), then difficulty is set so that the block is generated every 30sec while the reward is sliced to 1/5 the minimum - aka 1 coin per fast block of 30sec.
This way, the total amount of reward stays the same but since we have 'so much' hash-power, we can benefit from a very fast confirmation rate. Such fast confirmation rate will obviously translate into a more convenient 'currency' (higher velocity of money). This will make Darkcoin shine as -
a) a great currency
b) a great store of value
*p.s. I know there are orphan blocks, forks, and less security the shorter the block rate is, but we are talking about a very high intensity of hashrate.
Exchanges treat short-confirmation coins as less secure and thus require higher number of confirmations before accepting the transaction as valid. On the other hand, in some cases Bitcoin is accepted with just 2 confirmations. This kind of negates the benefit of having shorter confirmation times but you also end up with a bloated blockchain and bigger risk of forks. I think fast-block coins like DOGE will experience serious bloat issues. |

...unless this coin explodes so hard in its profitability and useability that almost every GPU miner moves to mine DRK
I agree this an overwhelmingly optimistic scenario, but i STRONGLY BELIEVE that the notion that 99% of cryptos are worthless in value is spreading throughout miners' notion as we speak, and with Asic coming soon, GPU miners will abandon all scamcoins and focus on 'One-[ASIC Resistant]-Winner takes all'. That winner will not be selected based on fairytale stories, cure names and alike, but on STRONG technological advantage. I think GPU miners primarily look at their wallet and their profit making... the moment that non-scrypt coins like sha-512, scrypt-n etc stop paying for them, they'll switch. And it's highly likely this will happen. I see Vert has positioned itself through coinwarz as the shinier alternative to scrypt coins etc that are "dead due to ASIC" etc etc, yet it is not an algorithm which is safer, more asic resistant, more cpu balanced (~1:3 top cpu vs top gpu hashrates) or energy efficient than X11 of DRK. But it's good that the miners are going there instead of here. |

Hi guys, tried to use Sgminer to mine Dkcoins but only get 45-47 khash/s with my Gigabyte 6850
Here is my .bat file:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx DISPLAY 0
sgminer -o stratum+tcp://drkpool.com:3333 -u xxx -p xxx -I 18 -g 1 -w 128 --thread-concurrency 6144
Using Catalyst 13.12 and SDK 2.9, installed sgminer as listed in the readme file except for the "source code" part which was not so clear to me.
Any idea?
You need a special sgminer 4.10, not any sgminer. By the look of your work units (it should be in the 0.0xx range) you are probably not using sph-sgminer: https://bitcointalk.org/index.php?topic=475795.0For reference, my 6850 can get ~1050 KHs @960 MHz. You should also use -k darkcoin when mining darkcoin. (that could also be at fault because you don't have that in your command line). Hi Alex, thank you for your quick reply. I downloaded the sph-miner and it's now working. Since you have a 6850 card, could you please post your bat or config settings? It's pretty basic really: setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 sgminer.exe -I 18 -s 1 -Q 10 --kernel darkcoin -o stratum+tcp://drkpool.com:3333 -u MYUSERNAME -p MYPASSWORD --no-adl Initially I had it on -i 19 but I reduced it to -i 18 as it is more responsive and has less rejects / better operation. I used --no-adl because it didn't start otherwise. -s and -Q are just personal preferences, it could work as well with higher values of -s and lower values of -Q. My card is a sapphire 6850 and I clock it through trixx. Mem speeds seem to make no difference whether 300 or 1000 MHz, while gpu core speed is set at 958-960 up from 775. Higher than 960 I start running into problems. Thank you. On my card, memory speed from 500 to 1000 mhz gave me about 80-90 khash/sec more...strange to say! On LTC mining there was actually no difference. GPU clock is 775 mhz. If I may ask, what Q and S stand for? Hmm.. probably the sapphire is different (?). You can raise the gpu clock - it'll make significant difference and the power draw/temps will still be quite low because DRK mining is far cooler / far less energy-drawing than litecoin. Q = shares queued to process. S = time dedicated for each share. If nothing is found after one second, it changes to another share. Theoretically, one has the same chances whether it is -s 1 or -s 10, but I like -s 1 because it reduces variance with an increased number of shares tried. |

Both, but bitcoin are better, easier to keep and to use : )
Bitcoin is better than gold, as long as the NSA doesn't bring a few gazillionhashes/sec with an ASIC farm they own to gain 51% the network. All it'd take for the NSA is a ~50-100mn USD equipment contract with some ASIC manufacturer (which is peanuts for their standards). Gold has no 51% attack problems or external uncertainties of what the NSA will do tomorrow. It has however other types of uncertainties like what will happen to gold production if the energy prices are somehow down by 80-90%, or what will happen if underseas mining start, or what will happen if gold can, at some point, by synthesized by low energy nuclear reactions etc. Why does everyone keep posting about the NSA taking over bitcoin. Am i missing something? There is NO WAY that one could achieve 51% of the mining rate. It would be absurd and overall and not cost effective as they would continually have to reinvest in equipment to maintain their mining rate. As the poster earlier than me replied, their cost would be negligible at this point. What's at stake here, is the hegemony of the USD. If Bitcoin becomes an increasingly popular alternative, they may take the order to break it. That would be last resort though because it would indicate massive panic on their side that would lead people to Gold & Silver with greater intensity than ever. |

1) Variable Rewards :
With DarkCoin there is a variable reward formula against difficulty (with a minimum of 5), so we cannot know exactly how many coins will been generated every year, worse in 5 or 10 years. Generally people don't like the "unknown". Can we find a formula that permit us to have a more controlled number of coin generated with the time? For example the range between Min and Max go from 10 to 45 million it’s huge. If someone ask how many coins in total? Waht to answers ? Between 10 to 45 ??
The best answer for this is probably "max number of coins is XX, but it will be probably less than that". Adam Back tweeted Darkcoin

@adam3us
"DarkCoin seems to be bitcoin fork with a multi-hash PoW and a p2p CoinJoin impl. DarkWallet does the same thing with BTC?"
I invited him to join the discussion (still trembling)…
@eduffield - perhaps you should connect with him…
Given that he tweeted about DRK, maybe it should be best for Evan to propose him to have a review of DarkSend's code when the code is ready and tell him that he would be honored to have him check it out etc etc. It'd be great for bulletproofing the implementation and a far better contribution of his time than writing here (which I suspect he won't do - but I may be wrong). |

Pick something and stop screwing with it. You're goofing around with the most important aspect of a cryptocoin's value capacity and trustworthiness. 20%, 30%, who cares. Just pick something and stick with it. I thin people just want something to talk about...
This is very important point (sticking with it). DRK is a a coin that is just 2 months old so some tweaking is ok, aside from feature additions which are always ok, but the inflation formula is a key parameter that should be set in stone, forever with no further changes. Even changing the parameter has the potential to shake the confidence in a coin, whether that change is inflationary or deflationary (which benefits most of the existing stakeholders). The rationale is this: If today the formula was changed to this and yesterday it was changed to that, then what is my guarantee as a bagholder / miner / investor etc, that tomorrow the same won't happen towards an unknown direction? Is a coin dev the Bernanke of the X, Z coin? This kind of questioning was introduced with the Doge situation and it wasn't good. |

If you push too hard for only investors to get in, the end-users who would most benefit from the anonymity factor (people in seriously oppressive regimes and the suchlike) won't be able to, and it'll become stagnant, and full of partially laundered money that rarely moves.
This can't happen. If the price goes up many times due to being a store of value coin, then the quantities needed for trading or trading anonymously, go down massively because each monetary unit (1 DRK) represents a much higher value: A $100 DRK will require 1/100th of the coins being liquid and on the move, in order to facilitate trade, compared to a $1 DRK. It's an auto-compensation mechanism. A scarce, low-inflation, high-value coin can also be a medium of payments/commercial transactions etc. The opposite is not true however: You can have any coin as a medium of payments but not as a store of value, unless it satisfies certain criteria. The choice is really not between a) A store of value coin which is unable to do payments and b) A payment coin which cannot hold value ...it's rather c) A coin that can do payments AND be a store of value - because these two are not mutually exclusive vs d) A payment coin which cannot hold value The problem of (b/d) is this: Coin competition is strong. In order to survive out there you must have the least amount of improvable weaknesses. Every weakness of yours can be exploited by others. You can have the best technical coin and a clone will come and then say: "Darkcoin was great but it is too inflationary for it to become both a payment medium AND a store of value... so we fixed their problem and we'll do better" => problem right there. This means we should create a darkcoin gravity wave for coin issuance over a fixed supply: more transactions, more fees, less coins issued Few transactions, lower fees, more mined coins. Heh... I can only imagine what would happen with fake transactions in order to increase the mining output  |
