Since bitlc is being hopped extensively, both 24/7 and intermittent miners are losing 20% compared to hop proof payout schemes.


I really do disagree with your analysis on the hopping bitlc.  People are not averaging 120% on this pool, the stats make that very difficult.  See, A1 and BC show an accurate share count for each round.  Deepbit and Bitlc hide  or randomly delay share counts so you have to guess where the hop point is and even worse when it starts...  You need magic sauce that I don't see everyone agreeing on what it is exactly.  My magic sauce, turns out, is just catchup and mayonnaise...I only averaged around 100%.  Big problem is that false guesses will cause you to mine at a really bad time and that kills your efficiency.  A much worse consequence since mining late or jumping in before 100%.  On a transparent prop pool, you can still net over 100% efficiency.  Spending 400K in a 7million round sucks, a much worse penalty than mining 24/7 and it helps those full time miners get a block.  So that is why hopping bitlc is very hard.

Bottom line is YOU need to try it and prove it before you talk crazy...like me!  Hop it and your favorite PPLNS and show me you can do it...You! Can! Do! It!, Handy!

Only if intermittent miners are intermittently mining late randomly in relation to the round.  If they intermittently mine early, they are golden Smiley  Ha

I know you are joking, but some people in this thread may not understand the humor, so I corrected it.

They are only "the same" (as in, same average reward)  if no one hops the prop pool.

just did a Google and forum search for "far enough" with or without PPLNS and did find anything, you are coining this "far enough".

it was a joke. You said "AFAIK".. As Far As I Know. Thats why I said you didnt know "far enough" Smiley

 BTW, mining prop the same way will do the same thing? Mining 24/7 on PPLNS is better than prop, but that is not what I said.
Occasional mining on PPLNS and Prop are the same so bitlc should stay the same unless it want to be a much smaller  inflexible pool than it is now.

Not true, AFAIK, PPLNS will penalize occasional miners.  

You dont know "far enough" then, because it doesnt. There is an equal chance of your shares ending up in a shift that doesnt get paid (because no block is found within the next 10 shifts) as ending up in a shift that gets paid multiple times (because several blocks are found within the next 10 shifts).

Of course you will have a higher variability then with PPS, but on average you will make exactly the same as a 24/7 miner and exactly the same as with any other hop proof payout scheme.

Perhaps looking at these graphs helps:
https://bitminter.com/stats/rewards

The top chart show shifts and their payouts. If you mine intermittently, you shares could end up in any of those shifts randomly, some are paid zero PPS, some are paid 1x PPS (yellow line), some are paid multiple times. On average, assuming average pool luck, you will end up on the yellow line and obtain 100% PPS payout.

Of course you will have a higher variability than with PPS, and probably a higher variability than a non stop miner, but on average you will make exactly the same per share as a 24/7 miner and exactly the same as with any other hop proof payout scheme.

Quite on the contrary, even if you mine at random times, you would be gaining substantially more with PPLNS...

Not true, AFAIK, PPLNS will penalize occasional miners.  DGM, PPS or SMPPS are better choices for hoping / occasional  mining. 

PPLNS is preferred for full time mining on one pool...good to maintain pool loyalty but not very flexible.

Mining at random intervals, or only during day or whatever, is not hopping and "hop proof" payout schemes do not penalize this behavior. Quite on the contrary, even if you mine at random times, you would be gaining substantially more with PPLNS or DGM compared to proportional.

if you are right, that kind of "hopping" rips off regular miners...but wait... hop proof schemes protect regular miners...unless they are screwing them to pay that "substantially more" to someone else...unless you are clueless

 Huh

In a proportional pool, hoppers will get, say 120% PPS and non hoppers 80% PPS (assuming equal average hash rate between hoppers and non hoppers)
In a hop-proof pool, everyone will get  100% PPS, there is no difference between hoppers and non hoppers.
Duh.

Been mining 24/7 for months >> never hopped >> tired of being called a sucker >> casted my vote >> switching to a PPLNS pool >> I'll check back with the site next month.

Many of us have discussed this at length, including you and I, in the past on IRC.  The biggest reason to switch was in order to discourage pool hoppers from leaving the pool.  After much discussion it was (I thought) decided that pool hopping doesn't actually hurt the pool or the workers in it.  Yes they reduce the payout for all of the shares since there are more of them, but they contribute to more frequent blocks so it all comes out in a wash.  It has been quite a while since I've participated in any discussions, so if the overall consensus has changed, then I digress.

That was never the consensus.  It isn't a wash.  There is a mathematical advantage to hopping.

Hoppers earn > full PPS value
Since mining is zero sum that means everyone else earns < full PPS value.

Hopping a prop pool and robbing the suckers may be unethical but at least it is smart.  Mining a prop pool and NOT hopping is basically say I prefer to have 20% of my revenue stolen from me everyday.  I could have 100% but I would rather have 80% instead.


Game theory.  There are three options you must choose one
a) Earn 1.2x per day but it requires a little more work and you must live with the fact you are stealing from others
b) Earn 1.0x per day.
c) Earn 0.8x per day.

Which options seems the best?  Which options seems the worst?

In the long run, assuming any fees/charged by the pool are reasonable, it all works out the same for people who have workers that sit and stay in the pool, and payout calculation method really doesn't matter.

If the pool is hop-proof that is correct however proportional pools aren't hop-proof.

Jine,

Do you have the statistics available (and the time of course) to generate some comparisons of payout methods using real historical data from the pool?  Per user would be great (I'd like to see if I would have made more or less with my miners since joining the pool) but a lot of work I'm sure.  Even some "this is a typical full-time miner of X mh/s, this is a typical part-time non-hopper user, and this is a typical hopper" over the last 365 days would be very helpful.  If you could also show what payouts would have been without the hoppers in the pool for everyone else that would be even better.  My suspicion is without factoring out the hoppers being in the pool, merely adjusting their payouts to the tested method along with everyone else, the amount of payout I'd have received would be roughly the same.  If you can in fact "remove" them from the pool for the statistics, I'd be curious to see if they really do hit regular users for up to 20% as is being claimed, or if the reduction in found blocks due to loss of hash power will offset some or all of that loss.

At the end of the day, I don't care if I make (obviously exaggerated) 20% of 50 BTC found or 10% of 100 BTC found in the same period of time, the payout to me is the same, 10 BTC, for the same amount of work I contributed.  I don't care about hoppers unless they're reducing that number either by taking an unfair portion, or if they're causing undue delay or downtime on the pool.  It sounds like that is happening, but as they say, "the proof is in the pudding."

Thanks Jim!

I already made a spreadsheet to calculate that for bitclockers, so I pasted data for this pool in to it and tried to make it work with the not so easy time formatting of the site..  I might have made a mistake somewhere, but it looks correct and the result (if correct) is quite sobering.

I solved for BTC/minute since hoppers dont mine as long as non stop miners.
For 100 shares / minute mining speed, and assuming hoppers jumped at 40% CDF, this is the result for the last 98 blocks:

Code:
expected BTC /min	0,00366269
Hopper BTC/min        0,00632149
Nonstop BTC/min         0,00300854

Expected is what youd get on a hop proof pool, or PPS.
Hopper is what the hoppers took.
Nonstop is what you got on this pool if you mined 24/7 and didnt hop.

Even some "this is a typical full-time miner of X mh/s, this is a typical part-time non-hopper user, and this is a typical hopper" over the last 365 days would be very helpful.  If you could also show what payouts would have been without the hoppers in the pool for everyone else that would be even better.

I mine when computer in my bedroom is turned on. I'm not interested in mining at a pool that forces me to mine 24/7.
This is a misconception. PPLNS does not require full-time mining, nor does it punish part-time miners (nor unfairly reward part-time pool hoppers). If you submit a share now, it will pay you a reward of (50/N) BTC for any block that is found during the next N shares on the pool. You can keep on mining or you can quit, it doesn't affect what that submitted work will earn you. If your hashrate's expected reward for 24 hours of mining is 2BTC, your expected reward for 12 hours of mining would be 1BTC, regardless of when or how you part-time mine.

PPLNS does have a lottery-like aspect similar to solo mining, but it is significantly more favorable because you are part of the pool's high hashrate, and your work continues to count even after you quit. If solo mining with an expected 2BTC/day hashrate, you might earn 0 BTC in a month of mining, or you might find three lucky blocks worth 150BTC. If you mine on a PPLNS pool for an hour, you might get 0 reward if the pool is unlucky, or you might share several block finds, and earn significantly more than expected for your work. Proportional has the same situation, miners suffer lower earnings if the pool is unlucky. However even the modest part-time miner will quickly see they are getting their expected earnings over time with PPLNS.

Proportional also has the "OMFG, when are we going to solve this ridiculous long block? I'm gonna quit" factor. PPLNS is much more optimistic, you start submitting work and wait for the block finds to roll in, you aren't overly invested in unlucky blocks, and nobody is punished for starting mining in the middle of a round.

Therefore I'm not enthusiastic over PPLNS. Maybe DGM would be better, but it's obscure and offers small rewards at the beginning.
Yes, poolhoppers are parasitic, and they wouldn't visit a pool without the base of honest miners.
But they massively contribute to finding blocks also , and finding many blocks attracts honest miners.

Those 115% PPS proxy pools by Clipse and Goat are hopping you and bitclockers.
I charted bitclockers stats,  did the math and calculated the effect:

@Jine: What N would you choose for PPLNS? Also, could you please enable changing one's vote for this poll?



Shame.  P2pool is looking better by the day.

p2pool uses PPLNS...
