So what you mean is you want to solo mine, but do it through a pool? Why not solo mine yourself? I'm sure you could get someone to set it up for you. Better still, why not p2pool? Your variance will be much less than that of solomining.
I could be wrong but I think phillips idea is to force people in to a solo mine situation when said person tries to connect with unfaithful gear which is putting it nicely. Not that he wants to solo mine which would just be nuts.

If you know they're a bad actor, why not just block them?
Again I could be wrong as I'm just assuming here, but it could be more of a long game. Sure it would mess with current people and ya, why not just block them. But again, if I am right it would also serve to protect the future so you wouldnt have to hunt, find and block each and every person that tries to be naughty.

Sorry, that's beyond me. I'd just block 'em.

Anyway, what's to stop them changing accounts and IP addresses? What's the detection heuristic?
Phillip would better to answer this as well as whether my assumptions are close to anything since I was just guessing at everything.

You are close.  

 First  if I decide to solo mine it is costly as I would need to run a server for little old me.  

  Second   The idea that medium pools can be attacked and their luck trashed seems to be a truth. Not paranoia .

Third   I don't like the idea that  this can be done to pools .

Fourth  So far no one has said they can easily  block this.   Switching ip's and accounts seem to make the attacker very tough to stop.

Fifth    so far  the solo mining option seems to be the only way to fully prevent this type of attack.  

Sixth  solo to merged auto switching  may help

Seventh  I would like other ideas on how to stop a 'bad luck attack' done by defective software.

Eighth the  problem  I have is  how do you block a bad gear hasher  if he switches around accounts.  You won't detect he is bad until he hurt you.  a  set of 4x 25th miners   is 100 th     run it at bitminter for  3 days and switch out to the next set of 5 x 20 th  miners so on and so forth.  Do this 30 days in a row and bit minter has  about a 10% luck drop.

Miners then jump to a bigger pool.  bit minter is damaged.   


 This is a real issue for small and medium pools only really big pools can tough this out since the attack is more expensive to do against a really big pool.  If you want to attack btcguild you need to use  at least 1200th  since btcguild has 12000th   more costly to attack them then bitminter.  Attacking cex.io would need more then 4000th    just too costly.

I don't see where my theory is wrong.  I rather be wrong.

 p2p does not stop the  problem  in fact they are more attackable then bit minter since they are under 1000th.  it costs less to attack them.

So asking everyone to solo mine and run their own server   makes mining worse due to so much extra power used.  But it is late I am tired so I am signing off for the night.

 I am looking for ideas to stop the danger that seems to exist here. Since two very big pools say this did occur to them to the tune of 400 + 200 coins.

I'm still failing to see the benefit to the attacker?  Other than them making money on bad equipment that wouldn't otherwise make any money.  Even if the solved blocks aren't being counted, they are still paying for the power.

Also, I think everyone is jumping off of Ghash because they almost hit the fabled 51% mark and no one wants to have hashing power that consolidated.  See article below.

Block withholding attacks have been discussed quite extensively.

Quote
The consensus is that such attacks are likely to remain rare and generally insignificant. The payout for the attack is simply too small and it's not an effective way to bankrupt a pool or get miners to desert a pool unless it's a particularly small pool, in which case there's generally no point.

Thanks for such an easy-to-use package! As a newbie, it was extremely hard to get started on a small scale until I found your product. Easy enough for even a cave-woman to use! Great work! Grin


Good luck with your mining have fun.  I happen to think it is  a better hobby then most.

Thanks! I'm sure many more stupid questions will follow, but so far I'm having a blast. Smiley

The issued has occurred twice according  BTCGuild and  Eligus pools.

At first I can understand the attacker's motives  would be he did not understand why he could not get blocks via solo mining  so he leached onto big pools to get coins. Not wanting to take a 2 or 3 million usd loss.

  He got caught twice by both pools.

 Now I am not making this up  or  at least those 2 pools have accused a big  miner of the problem.

So a lets be nice and say his gear/software is finally fixed and he just mines for coins and no longer mines with shit gear/bad software.

No worries for all of us  if that is the case. 

  But just remember it was done and can be done again.

  I am fine with the fact that  some big miner has a big cannon he can point at my pool and blast my pool with bad luck.  Do you know why I am fine with that.

 I don't run or own a pool.

  So I can skip around I can be in six pools and I can protect myself in a lot of ways.

 Since the bad luck cannon can't hit every pool at every time.

 I only need put 20% of my hash in 5 pools  and at worse  I get some damage in one pool.


True and real pool owners are the ones at risk since their pool can get shot at and they don't get to jump around or spread the risk of the attack. So good luck to them and I hope then can protect their interests. Find good detection methods of a clever attack like this if indeed it happens to them.

They've not just had a bad run of BTC blocks but NMC also?  Have the Eligius attackers changed their tactics and moved here?

Multipool
    Why don't you go mine  Bitcoins at  some other pool. Then report back on how many blocks you find. KOI seems to find blocks with the same Thps. Just seems like something is wrong.

I am getting concerned about multipool being on this pool in this environment.

As a pass through of other miners, multipool could be 90% block withholders and we would never know.  And they make an ideal cut out.  Who am I to sue if it turn out they are collecting rewards that are rightfully mine?

I am all for bitminter growing, but I don't like the sudden appearance of 20% of the pool from a group that doesn't deliver a block solution for weeks.

Let's have a serious discussion about the merits of allowing pass through accounts.  What is the up side of having them on bitminter?  And how long do we allow them to collect 17% of all rewards while their history has them contributing a statistically unlikely amount themselves?

If you don't mind the slightly dirty feeling of mining with a BFL associated pool, Eclipsemc.com Bitcoin Mining Pool also allows for 443 mining. That's the only other pool I'm aware of.
