How often does someone who has enough hash rate to hop profitably really have any significant downtime?n it is worth it imho.

Hop profitably or mine on a pool profitably. If you really meant 'hop', I don't understand what you're saying. Which probably says more about me than you, but still - erklären Sie mir bitte?

die Welt kann nie wissen! well, atleast what the heck I'm babbling about, anyhows. ;p

Hop profitability; for instance someone with 200MH is not going to get enough shares before x%(40%?) of current difficulty shares to make it worth moving to another pool on prop. Someone much more proficient at the math would have to explain it better. But the jist is that on proportional unless you are one of the highest hash rates at the pool you lose your butt big time after the top hashers move on.
I'm not sure if that's what you were asking or if that is the only part I had not described very well though.

How often does someone who has enough hash rate to hop profitably really have any significant downtime? A safe measure is adjusting the % of hash rate tolerance and the time tolerance. We also have the benefit of having a human checking such things. I'd like to think the pool op would not punish his highest hashers if they had a situation that would trigger a drop of their shares. It would be pretty obvious if the same person just happened to have 'problems' several times in a row after acquiring the optimal shares.

So totally subjective human checking. Yeah that would be a pool I would never use.

PPS, PPLNS, SMPPS = guaranteed hop proof AND doesn't punish miners who disconnect.
scheme full of human subjective fail = not guaranteed hop proof AND punishes miners AND subject to misuse and abuse.

Also luck = variance. PPLNS has just as much variance as prop thus in the short run luck plays just as much of a factor in payouts. So it "rewards" luck just as much as prop does. Of course thinking a pool is superior based on luck is dubious. This isn't a single hand of blackjack this is billions of shares per year. It all evens out anyways.

There is absolutely no purpose for prop to exist under any circumstances except to give the uninformed, clueless, and stupid the "option" of getting rapped by hoppers who annihilate their earnings.

I got a quick fix for you. Anyone that drops off more than 10% of their starting mining power for more than x time. drop their shares. period. the only people that will put off is the hoppers.

And anyone who loses connectivity, power outage, mining crash while they are at work.

yea, yea. I knew that someone wold come and say that. Guess that's what I get for not spelling it out..

yes, other options require less human interaction. But prop pays for luck, and if it can be made to work then it is worth it imho.

Err... n=1=solo mining. n=0.5 would be... umm, kind of impossible I think? A share is atomic.

I think mostly people use the N in PPLNS as shorthand for N*D shares, not N shares.

Sorry n=1*difficulty, n=0.5*difficulty.

I'm probably going to switch to pplns. I was thinking about making n= 1/2 of the difficulty, or is that the high for n.

I believe that is a rather low n. Most use n=difficulty. Larger n smooths out the variance but it also can seem "unfair" to a new user. It isn't but I believe that is why an n=1 is commonly used. Still n= 0.5 is still hop proof just be aware that a significant number of rounds will go unpaid. Nobody loses anything but the variance can be "rocky".

Also I agree with the post above. Meni likely knows more about mining math, reward systems, and mining exploits than any 20 people I know. He has an ebook which covers every reward methods with pros, cons, simulations, analysis, and lots of math. It should be required reading for any pool op.

I like n=1. Good balance of time to payout and variance. But DGM is much more configurable, and with a few pools ops now with lots of experience, and with the inventor (Meni Rosenfeld) being an active forum member, you should be able to get a bunch of advice and maybe even help.

My advice: whichever system you choose, don't change payout methods mid round Wink

There are proven hop proof solutions. Instead of methods which punish non-hoppers why not just use a solution which is ... and call me crazy ... actually hop proof like PPS, PPLNS, SMPSS (and varaints) and DGM?

Right, so it would be fine for DGM to use a $block_reward = 40 instead of 50...

But now that I think about it, even if you changed the block reward it wouldn't matter. The score is independent of the block reward, it just divides up whatever you feed it as the reward appropriately, according to contribution.

Heh... you could even random(1, 50) the block reward, then award whatever isn't doled out to a lucky participant(s).

No, I imagine it would have to be ongoing. You just wouldn't be able to change the proportion of btc for the gamble, but that's no deal breaker.

Not if it's in perpetuity. Are you talking about a one time thing?

So you just don't include the other 10btc distributed randomly then? Won't that have an effect on the overall score?

It could, just set the block reward to 40 instead of 50 and DGM should be fine.

There was a Russian pool that did a gambling thing that was fair. Nothing wrong a with a gambling payout system as long as it's transparent and can't be gamed.

There's an idea for you A1BITCOINPOOL - use a payout system that gives a slightly random payout. Eg, start with PPLNS but base the payout on 40btc instead of 50. Then split the remaining 10 btc among ten random miners. You have fair payouts with some luck involved. I'm not sure if this would work with DGM.

Actually, I would prefer Prop. If it were not for the hopping thing, you have that little gambling itch covered where finding blocks quick, pays better.... I would probably only do that if I had 5GH+ at present dif though.
