I'm less confidant in that than you.
Over $18 million in bitcoin moved in just the last day, $120K is less than 1%

Someone with Hash power to waste on such nonsense.

Current pool distribution.
https://blockchain.info/pools?timespan=24hrs

Did they actually give you a real name and location?  Do you actually know who it is that did this?  


If so, you should post all of their details immediately.  


Also, is there any legal recourse that can be taken?

Oh !!

Thanks.

Nice work WK and Luke! Obviously you've put something in place to prevent them from simply changing btc addresses and carrying on...

And thank you for being so honest and trustworthy WK, I've agreed with every decision you've made so far and it's clear to me that you have very high ethical standards as this would have been an excellent opportunity to fill your personal wallet with an extra 200btc

On a side note, looks like automatic NMC payments are working nicely too

This is fucking awesome!  What an idiot, or bunch of idiots!


At the current rate of $601.50 per BTC they have had to forfeit over $120,000.


Ha ha ha ha ha! ROTFL!!!!!


No matter what their attack actually accomplished, I am pretty sure it wasn't worth a cost of $120,000.

There is, 1-2 minutes.
Miners cannot lie positively (claiming there is a share at X when there isn't) because the pool double-checks every share, but they CAN lie negatively (claiming there is no share at X where there is) which is what block withholding does.

What would be the incentive of actually running a block-withholding attack, when all it actually does is reduce the profitability of having run that hashing power in the first place?

Is it sufficiently-compelling to hash at a loss simply to reduce the payouts of other participants?

Sorry for being not too clued up on the software that runs all the hashing to do with Bitcoin, but
why is there no time limit for work to be returned ?

Having been a SETI/BOINC cruncher from early days , to present , there is a time limit in place, that if you do not return
your work in a given time period the work is sent out to someone else.

I know a month for SETI is ok - maybe a much less time period should have been in placed into Bitcoin Mining
so as you had a small window to return your work - if you had a power loss or some internet time - you lose a little - but not
a lot.

Nice work.  WK.

Work done for the pool is useless for solo/any other pool.  The hash is only valid for the pool it came from, with the payment to the address the pool told you to put.  Otherwise the pool's hash (since the pools check your work) will not match yours and it will be rejected.

Could they be not discarding winning shares and instead using them in solo mining setup?
Guarantee themselves benefits of pooled mining and win some by solo mining winning shares by withholding from a pool?

I have a theory. The network hashrate has just jumped up 14PH approx as per bitcoinwisdom difficulty.

Perhaps this is a large farm, concerned about rising difficulty and wanting to minimize the impact of difficulty increases. They mine on btcguild/eligius and submit low difficulty shares (for which they are paid) and discard winning shares (so the network hashrate is artificially low). Profit ?

All true... I'd give up my portion to put towards improvements...  There's probably enough miners here who'd do the same.  If Eligius is made better and faster, more miners will come over

The ~200 BTC belongs to the miners affected, IMO, not in any way a donation to Eligius.

On a side note, almost everything important is on SSDs except for the webserver... which will be shortly.  Software is needing some updating/rewriting to get more speed, though.

Nice job catching them!!!
I think out of the 200 btc, Eligius should acquire solid state disks (such as nimbus data gemeni flash array).  Db will never have any issues and rebuilding/reorganizing etc.. will be a thousand times faster. 
Just my 2 cents. 
Overall, we should beef up Eligius and spread what's leftover

Another point, couldn't we analyze these 2 addresses for relationships with other addresses to see if we could infer identities behind these addys?  Maybe not, but it could yield some interesting leads...

How is a 2Phps pool (2% of the network) going to come close to a 51% attack?

If this is the case and it is the pool with the biggest percentage right now, then they are after 51% and seek to undermine, control and possibly destroy BTC or at least damage the reputation.  There has been speculation about them hiding their hashing power by splitting it and obscuring the pool that found the blocks, but since the miners there refuse to leave to another pool, I don't think much if anything can be done.

Regardless, at least these people were found and have had their btc frozen.  It's a possibility that their delay in attempting to withdraw the coins was an attempt to slide under the radar while they were busy doing the same to other pools.  No matter what, we can go ahead and figure that they are reading these posts and are either laughing about it (thinking they got away with something), or seething  because Wizkid made an official post about them.  Either way, we need to stand with Wizkid, Luke Jr and Eleuthria.  Threats are just that...threats.  Terrorists seek to cause fear amongst the people.  Extortionists just want to line their greedy pockets from other people's hard work.

Has anyone taken into account that instead of another pool being responsible that it could be a ASIC company that has failed over and over again to ship products to consumers who pre-ordered months in advance?

Not really useful, since you could always split yourself up to a bunch of small accounts... and even if you weren't attacking you'd prudently do this to avoid any delays, even if they were small.   ... if you thought your odds of getting a block soon were good why would you be on the pool in the first place?

I'm just curious, how do you detect it, and know they aren't just unlucky in ever finding a block?
