This is going to sound noobish, but on the vdiff settings, I can either tick the box so it uses the pre set minimum in my user profile which is 8
or untick it and it will set it manually for independent miners which is also 8
so is this just the starting point and the pool still auto adjust per miner, or is it set at 8 untill I change it?
The pool is still auto-adjusting your diff, but will not go below your minimum (that's why it says minimum right?)
You don't need to set that your self - some miners have a problem if the diff is too low and it takes longer until they reach their hashrate, hence the setting for a minimum, which in such cases (if you have problem) should be set to about the half of your normal diff or at 2/3 max to 'jump-start' you miner's diff

Love how this pool hits 40ph and stops hitting blocks. Can we say withholding!

Exactly why I stopped mining on here. Took me only a couple of weeks to realize it by doing the simple math.

Now under 40ph and hit a ton of blocks. I have a remote miner pointed here because it's a pita to get changed. All my other miners are on Kano and couldn't be happier

Can you explain how you did that? I wouldn't have thought simple maths is enough to prove your point in this case, so I'm keen to find out how you determined the correlation.

I know you're trying to belittle me since im a noobie, but I'll bite anyway, after some time mining slush, eligius, bitminter, kano.is, I took my speed, time mining, number of blocks found, and final payout for each block. Averaged it out, and found that slush was by far the worst for me.

Not trying to belittle you at all and I apologise if I came across that way. I've been working on this problem of Slush's luck for a while -- it's not an easy one to analyse -- and I wanted to know if I'd stupidly missed something simple.

Your maths is fine as far as it goes (EDIT: I was hoping for something that showed how the pool's hashrate affected the pool's luck), but you might also want to consider ways to make the comparisons between pools more valid. For example (assuming your hashrate is constant) compare just payouts over a similar number of blocks rather than similar time period, and I would use a large number of blocks.

Even over a hundred blocks, you're still going to see variance of about +/- 20% of expected. If one pool has a not unusually unlucky hundred blocks and another has a not unusually lucky hundred blocks, there could be a 40% difference between them - just due to variance.


EDIT: Also, if you're just considering time periods rather than blocks, then difference in variance could be exponentially greater.

I understand the luck aspect, and the possibility of one pool getting extremely lucky and one not being lucky at all, but when I noticed that what it took me to make in 1 month in BTC at slush, I was able to make in another pool in one week (despite not having a ton of luck the week I mined it), I knew something was up.

Dear miners,
we would like to inform you that we have detected and resolved an unintentional block withholding attack.

The issue has been discovered a week ago and we have immediately taken an action by contacting the particular miner. The cause turned out to be a bug in a custom mining firmware, which has been promptly fixed by the miner. We have no indication that there was any bad intention. The fixed firmware solved two blocks since then so we can consider this issue as resolved.

A recent time period of worse luck can be at least partly attributed to this incident.

Block withholding attack is a well-known weakness of the whole pool mining principle and no public pool is immune against it.

As a by-product of the bad luck investigation, we have implemented a new method how to mathematically prove that the pool does not cheat on miners. This feature will be released after the public interface has been tweaked. The release is planned towards the end of next week.

Well, the correct action would be to deduct the rewards paid to a miner who was withholding, and distribute them to the miners who were not paid what they should have been ...

It doesn't matter if it was accidental or not, the miner caused it and received payments that they should not have, and should have gone to the other miners.

Come on, does anyone really believe it was a "random" miner?

The correct thing to do is to simply inform the public:

(1) What is the make and model of the miner?
(2) What is the version of the custom firmware?
(3) How to detect such "rogue" miners?

Why did the pool operator not release such public service announcement?
