I don't think the user owes anyone anything or is liable if it was an honest mistake. The only way they would be liable financially is if they knowingly stole from or sabotaged the pool, which is unlikely considering the fact that they were also hurt financially.

This must have been a very large farm in order to hurt BtcGuild by 10 to 15%, so it's very unlikely that they would also want to reduce their own earnings by that amount on purpose.

eleuthria, is there any reliable way to flag and deal with this type of issue sooner in the future? I assume it must be fairly obvious for very large farms.

The probability this was an honest mistake is zero.

You have a group with more than a petahash that suddenly decided to pool mine and they solve no blocks for a month.  A petahash is not brought online overnight.  There were certainly mining solo before this, and discovered problems with solo mining.  There is absolutely no reason for such a large operation to pay pool fees.

Further, Michael since you are listening now, you should realize that cockroaches never appear alone.  Dig deeper and you will find more problems.  We pulled out of your pool over a month ago because the bad luck was statistically unbelievable then.  This is not the only cheater in play.

I'm not sure I have caught every post on this issue but I believe I saw a ways back that it was said that this miner had moved from eligius to BTCguild and as a person who has been mining on eligius for months I can say that the luck hasn't looked so good over there for a while.  It's too early to say if it is turning around but it sounds like whoever this is had to know before they moved here.  If they really can't fix it, then I imagine they will move to another pool and keep on scamming.

I'm a fan of self control, but only in moderation.

That would be my guess.  Which pool should we refer them to? Cheesy

I have heard that Spondoolies is testing their miners in pools right now.  I have also heard buzzing about the fact that they are not yielding as many solved shares as should be theoretically possible.  Could this be because of a hardware bug in their chips? 

I have requested a refund on my miners for them and have swapped to buying up miners on eBay and buying coins at the current low price.

That was perfect.

Never attribute to malice that which is adequately explained by stupidity.
Great quote, but we've already seen enough stupidity in bitcoin and we're about due for some more malice...

Payback time would be when min share difficulty on every pool is greater than a UINT32. That's when they can take their crap hardware and shove it ...

I suspect they knew they had a problem, but I doubt they had any clue how to fix it.
Either way I think there's little that can be done.  And I for one am not going to demand their heads on a silver platter.

What kind of bitcoiner are you?  Don't you know that in these parts, everybody is all pro-anonymity...until you don't like them, in which case it's only reasonable to demand that a user's information be given out publicly to an angry mob?
Maybe I should switch from bitcoin miner to pitchfork manufacturer? Grin
So long as you take preorders for forks at a price that never allow you to pick up enough hay to...

This caused me to have a laughing fit in the middle of my office. Thank con

The word on the street is that public pools are under block withholding attacks.  Malice it is.

As one of the loudest voices accusing DPoS of pointlessly crying wolf, I wanted to publicly apologize for doing so.

Also, thanks to Eleuthria for doing the sleuthing to find the problem. I realize it's an ongoing issue and not necessarily settled, but I wanted to own up to being reactionary while the broader issue was still being discussed.

Thanks - I'm just playing my role as the guy that goes to a town that has 50 kids crying wolf and then telling them there really is a wolf in town now..  that's my torch to bear

then the town usually goes into these stages:

Fallout (blame, compensation, etc)
Ramifications (questioning awareness & prevention)
Reflection (are we still in Kansas anymore?)

It is requires special logic in ASIC to withhold winning blocks in HW while keeping the non winning blocks.
It is relatively easy to withhold winning blocks on any miner in SW.
We are open source miner.  We compile official Con's cgminer from his repository in our official image. Of course, anyone can compile block-withholding SW for our miners, but the official image that we release and test does not do it.

I think we need an extreme change with the bitcoins. We are absolutely near the point where electricity is more expensive then the worth of an mined bitcoin. What we need is an sicgnificant increase of the bitcoin price. It has to go up for more then 100%, if not we all have to switch off all our miners.

And what "extreme change" would you propose.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.

Is this the same street that says Elvis is still alive?  It's still all rumors at this point.

If you have a miner that CAN'T solve a block, then you need to point it at a pool to at least get some return, even though you're bringing everyone's earnings down including your own.

If you have a miner that CAN solve a block I still can't see a scenario where it makes any kind of economic sense to stage an attack of this kind.

If you have a miner that COULD solve a block but ISN'T and you don't know why, then you'd put it into a pool.  If and when you figure it out and fix it you'll pull it from the pool.

My pet theory based on my Magic 8 Ball is that it's the last of the three.  Maybe.  But I might change my mind tomorrow.

There are some power sipping beasts on the horizon.  I just interviewed a company about one a little while ago.
I should have that ready for Amsterdam.
But you are right we are at a tipping point.

I reset the stats on the accounts that were frozen, because they've fixed the issue (confirmed solved blocks on Eligius with the same wallet as their Guild account).  I want to make sure I can accurately gauge their shares vs block solves.  Their accounts are disabled from receiving any payouts at the moment.

Kinda screwed up the pool speed calculation, trying to tweak that.

Before anybody says it:  No, they are not mining on the pool right now.  We're just stuck on a block at the moment.  ~5x current diff in shares submitted since the last solve.
