I have the same issue the Ghps (not work share) is going down. I had 620Ghps mining here, 3 weeks later it's 530Ghps!
What kind of ASIC device(s) is this? What hashrate is your mining client showing? Are you getting a lot of rejected work? Hardware errors? Connection problems? |

Sorry, Bitminter isn't a non-profit organization.

98 % 2 days 9h52mins amazing  To boldly go where no other pool has gone before We've had 99.9% CDF before, and we've also had 14 day rounds (a long time ago). While annoying, it's nothing special I'm afraid. Whoa, wait Doc - it is free! Am I losing my memory or did it "cost" a 0.5% donation at one point?
No, auto cash out was always free. And actually...now that I think of it, do mining pools qualify for status as non-profit organizations? Because logically, if the IRS wants to tax mining income at the income rate - donations to the pool should be equivalently tax-deductible for miners.
I think most pools are for-profit. |

Manual withdrawal only costs 10k satoshi, so for withdrawals > 0.02 BTC, its cheaper to do them manually since at that point 0.5% of the sum becomes more expensive.
Auto cash out doesn't cost 0.5%. It's actually completely free. So auto cash out is always cheapest. But you may want to cash out before reaching the minimum for the auto cash out, or you may want to send less than your entire balance somewhere - in those cases the manual "send coins" is useful. |

Most likely variance. 600 when lucky, 560 when unlucky. Actual hashrate 580 ?

I think it is normal. It is the absolute hashpower of the pool is growing, so your share is going down because its stable.
Yep. When the pool hashrate goes up other people are finishing the shifts before you can get the same amount of work in. That's why your work per shift goes down - the shifts are shorter time-wise. |

will bitminter client be supporting drlibitt systems "avalon thumb" asic usb miner, or any of the drillbitt miners?
No immediate plans for this. If it is easy to add support I may do it, but those machines look a bit slow at this point.. I don't know if they will be popular. |
|
|
|
That being said, would it be worth lowering the set difficulty in the miner to 512 (the next lowest setting) and setting min diff in the worker setting on bitminter to the same?
If you think 1024 is giving you too much daily variance then you can do this. I think 1024 should be fine though. |

Dragon miners were made extremely poorly and do not function well with variable difficulty. I believe their default is 1024, and I'm assuming that's what you set it to on BTC Guild, which is why it is showing up properly. I'm pretty certain you can do the same with BitMinter, the only question is if the BitMinter variable difficulty is decreasing it, causing the miner to effectively lose speed due to its complete lack of variable difficulty support. Basically, the miner would continue to run at diff1024, but the pool is only crediting you for 700-800ish because that's what it told you to work at instead.
Yes, in this case please set minimum difficulty 1024 for your worker on Bitminter. That's under "my account" -> "workers" in the website menu. Click the gears icon to access the setting. But I don't think Antminer S2 is broken the same way as the Dragon miners? |

Has anyone else had intermittent problems accessing the big stats page on the website over the last 5-7 hours?
yes it pops up as all blank. but I still have been mining To me everything looks normal. If you're still seeing this, could you send a screenshot to operator@bitminter.com ? |

Thanks newar! So DrH, which needs updating - the pools list or the Bitminter first post?
I thought Bitminter was listed with merged mining already. Looks like the pools list needs updating. Bitminter is merged mining namecoins. |

bitminter has my bitcoins/namecoins and site staff/ owner is ignoring me
I was a little behind on support messages. I wasn't ignoring you or trying to steal your coins. Don't you think it was a little early to assume so? |

Today marks 3 years of Bitminter ! A big thank you to all the current and former users. I appreciate your support. It's been a great 3 years.  It's also nice to see that some who joined during the first few weeks are still mining here. Over these 3 years we've had 271725 users mining with us. But there is room for more, so tell your friends! |

We are back again. Apologies for the connectivity issues.
What's the block made by unknown? With the connectivity problem the mining server was delayed in reporting who made the block. It's cs3gallery. The name is now up on the website. |

Our mining server appears to be having connectivity issues of some kind. I'm talking to our provider.

No work you already did will be lost if you stop mining. The client just shows the numbers for "this session". That is, since you started the client.
You can see work you did on the server under "my account" -> "workers" in the website menu. Switch the filter at the bottom to "all time" if you want. Also under "statistics" -> "shifts" you can see how much work you did per shift.

Do you think that "bad hardware / software" exists and that could make the pool vulnerable?
Like I said, all mining pools are vulnerable to block withholding attacks. All pools. Whether bad software is still out there, I don't know. But as we have seen, it can happen. Bad hardware is very unlikely. All the ASICs I heard of so far simply look for anything from diff 1 and up. Doing something else would require more logic on the chip. |

So, Dr. H do you think this pool is vulnerable to abuse? And if so, what do you think should be done. And if NOT, why do you think so?
All mining pools are, and have always been, vulnerable to block withholding attacks. These attacks are rare though. There were those guys mining at BTC Guild and Eligius who had a programming error in their software, having to do with how they determined whether work was above or below pool difficulty. I also read on Reddit someone claiming to be block withholding on Ghash on purpose. Those are the only cases I've heard about so far. The real solution would be to get protection against block withholding in the next Bitcoin hardfork. Other than that, pool operators have to watch users with suspiciously bad luck. Accusing everyone with slightly bad luck is not a solution. I don't see it as a solution to stop pooled mining either, and have everyone solo mine. For most miners solo mining is not an option. There's no reason to believe mining chips would do block withholding. That would actually require more logic on the chips. Help, I keep trying to find the answer to this. Why cant someone send in a huge amount of work that they have already submitted to another pool. How does GHash.io what (Non-block find work) I have submitted to bitminter and vice versa? Whats to stop some clever coder from submitting non-block finding work simultaneously to multiple pools?
Pools only accept solutions to work they sent out, not work sent out by other pools. |

So, that's the issue for me and others with respect to multipool. Multipool was reaching "my" limit of unreasonable behavior for the size of the hashrate. In a manufacturing operation, you expect a mean performance and you have upper and lower control / spec limits. if you are drifting far from the mean, consistently, you investigate why.
Problem is that this was not particularly bad luck. You can't call it consistent either, because they mined for a very short time. Complaints started when their mining was at a CDF of about 70% which is just silly. Even at 95% CDF you may think this is really rare, but it's not. If you crashed your car 1 out of 20 times you drove, would you still say that's so rare you would never expect it to happen? Can anyone confirm the calcs above?
If your percentage of the hashpower in the pool meant your part of a block was 0.1 BTC and you got 0.096 that would mean you paid 4% in fees and donations. If you have 1% fee + 3% donations, you can reduce the donations and keep the same perks by activating the pro minter perk. With the pro minter perk, that's the only one you need to cover with donations - as long as it is on the other perks are free to activate without additional donations. So other then setting the entire pool to solo mining 2 hours of every day or 1 hour of every day or 3 hours of every day what would you suggest?
I'd suggest we finally do the hardfork on bitcoin that has been suggested long ago, which would make block withholding impossible. |
