If Eligius is withholding payment to this user (and rightfully so), will he redistribute those 200 BTC to the other members?

And what about here on BTC Guild?

I noticed luck has gone back up.  So was it really bad luck before, or was it an attack?

OK, they may have inadvertently diluted everybody's earnings, but that is not theft;  one could argue that they were suffering as well by not getting their share of any blocks they should have declared.

There's a lot of accusations flying around here.  Now IIRC the issue was that some big miners did not appear to be pulling their weight in terms of blocks solved against hash power, and this turned out to be a previously undetected flaw in the software which resulted in results not being submitted.  After they were suspended and investigated, it seems the error was found and corrected and they are now mining again.  If that is actually what happened, then they have not stolen anything.  OK, they may have inadvertently diluted everybody's earnings, but that is not theft;  one could argue that they were suffering as well by not getting their share of any blocks they should have declared.  If I'm wrong (and I really can't be bothered to go back and read all through it again) then I'm sure somebody will put me right.

Do you know for certain whether your own mining rigs are submitting results correctly?  I certainly don't, and I doubt that you do, for with the difficulty at its current level most small miners are now unlikely ever to solve a block, and any fault won't show up statistically.  But even knowing that you are probably only taking and not giving, you are presumably happy to accept a share of the pool.  Are you stealing from the other pool members?  I think not - after all, that's why we joined the pool.

Hindsight is a wonderful thing when apportioning blame.

I can't speak anything to compensation obviously but what can he really do to recover ?

I mean, lets say I steal money from a bank. I hide it really well, sure I go to jail buy unless some dumb ass stumbles upon my stash which doesn't apply to this situation, the money will always remain un-recovered. Point being there's nothing he can really do to reover anything.

BTC Guild's PPLNS system does not require block confirmations for blocks to apply

This situation is more like the grocery store pouring the milk you purchased into a paper bag and then getting indignant when you ask where the all the milk you paid for went.

Eluethria admits that this one group was stripping around 20% of earnings from every participant in the pool for over a month but he hasn't done anything to recover funds and compensate those that were cheated.

This isn't meant to be a negative but people don't generally invest more time or money in to something that what they feel isn't required until something like everyone leaving happens which in this case never will because some people just accept stuff for what it is when it isn't which with shit like luck is easily argued away with luck being what it is by nature.

Stupid ass analogy but...

Here's a paper bag for your groceries, we could have opted for plastic which is generally stronger but we wanted to save the store som money. Just be careful with the paper and it shouldn't rip thus dropping your groceries all over the ground.

I clicked back in the thread to 05-10-14 (3 months back from 8-10-14) and didn't see any mentioned to the withholding attack.  Is there a separate thread detailing this discovery?

Anyone seen this?  Specifically the block withholding attack at the bottom of the roundup.

Regarding the hard fork to make block withholding impossible:  It will never happen.  AFAIK, that hard fork would also break all existing ASICs.

Granted, a hard fork does NOT need 51% mining power to be implemented.  What matters with a hard fork is the market (people who accept/trade Bitcoin) moves to the new fork.  But unless I'm mistaken, the secret data used to prevent block withholding would be incompatible with all existing mining hardware, which will immediately make such a fork very hard to achieve.  It would more likely kill BTC entirely due to the competing standards.



As for variance/luck/withholding:  I'm monitoring closely users with bad share/block ratios.  Unfortunately, there's really not much else I can do.  It was around June 9th we had a pretty big dive.  But then we had a decent rise that roughly offset it before going into 3 days of consecutive very poor luck, caused mostly be a few 5 and 6 hour rounds.  However, the pool was at 96.8% luck for the last month before the dive, and rising.  99% is "neutral" in the sense of expectation, since you would expect a ~1% orphan rate which means 100% is actually slightly lucky.

The pool has not grown significantly, nor has the difficulty risen in the last 3 days.  The current dip appears to be luck, not withholding, based on the fact that the long rounds mean all the prior speed (11-12 PH/s), which was performing right within expectation for most the last month, weren't finding blocks for 5-6 hours along with the new speed that joined.
