keeping people from using someone else's solve hash)...
Nobody can use a hash belonging to someone else. Block withholding means that a Miner Withholds a block solve, but it can't be used for anyone else on nor on any other pool. There is nothing you can do to prevent a miner from checking a hash to see if it meets difficulty before submitting it and withholding it if it does meet difficulty.

I still fail to understand why anyone would withhold a hash that has met difficulty, surely they have nothing to gain from doing this ?

The less blocks are solved the longer their hashpower will remain profitable to lend because it slows down diff increase.

@ CK, is the best share meant to reset to "0" whenever someone hits a block & bestever to remain ?
my "bestshare": 44363102898.412689 couple of days ago but i think recently someone hit a block ?

Bestshsare does reset for everyone when the pool finds a block, and bestever doesn't reset. The last block found on this pool was 1 day 14 hours ago. However if your user or worker was offline when the block hit or across the last pool restart then it may not have had its stats updated at all.

There is nothing you can do to prevent a miner from checking a hash to see if it meets difficulty before submitting it and withholding it if it does meet difficulty. I still fail to understand why anyone would withhold a hash that has met difficulty, surely they have nothing to gain from doing this ? They have plenty to gain from it, and nothing to lose. Let's say I am a malicious user and have written software to withhold any block solving shares. Let's also assume I own 5PH/s of gear, which is only about 1% of the entire network. Not a tiny amount of hashing power by any stretch. I put my gear up for rent on any of the sites. People start renting my gear and pointing it to this pool, for example. They're hoping to hit a block. Well, because of my hack, they'll never hit that block. However, I will still get paid for the rental. Now let's say you don't like somebody's pool. We'll pick on kano's pool here (no offense at all to kano, it's just an example). You know that my gear has the block withholding exploit in it, so you rent my gear and point it right at kano's pool. Everybody on his pool is all kinds of excited that 5PH/s just showed up and is looking forward to the payouts. Uh-oh... no new blocks are found by my gear. However, blocks are still found by the existing hash on his pool. So... everyone there complains that the pool is unlucky. I don't really care because you rented my gear and I'm still getting paid. Heck, even you will get paid for any blocks the pool finds. Win for me, win for you, loss for everyone else on kano's pool.

On PPLNS if they do that, the person paying for the rental is expected to average a sizeable loss also. Their expected loss % of 25 BTC is their hash rate vs the whole pool. So if the pool was 2PH (as it is now when we just found a block ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ) if someone withholding with 5PH started mining on kano.is, they'd expect (of course) to find one block on average per Nd share diff they mine (currently 72.7 billion Diff shares) For that block they get paid nothing (also no one else on the pool gets paid for that block) However they are sending 5/7 of the pool hash rate to the pool, so they would actually expect to get 2/7 of their expected payout. i.e. they'd mine 25BTC worth and expect on average get back 7.14 BTC (a 17.86 BTC loss on average) from their cost to mine - getting that when someone else on the pool finds blocks. Of course they could be lucky and find more blocks than they expect ... and not get those payouts also ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) or they could be unlucky and have to spend a lot more than 25 BTC for each block they find and withhold.

I fully agree that the persons paying for the rental are going to take a pretty sizable financial loss. However, it is not a complete loss (they'd still make *something* if and when the pool found blocks). As the gear owner, I'm still getting paid regardless. It's only the miners on the pool that get shafted.
As you correctly point out, PPLNS mitigates things, since risk is transferred to the miners. Had I chosen a PPS pool, then it would be the pool operator that eats the losses.

Well, there where two interuptions in the connection for about one second duration. Cgminer reconnected directly, looks like a "normal" connection loss from europe to usa. That I see mostly at this time. I asked con a year ago about those connection loss and he helped me finding out this. So, no problem at all.
