The calc math is roughly correct Id say.

What I see is happening is quite simply LARGE pools "outluck" small pools on block hits.

Think about it like this, if you had 90 people flipping coins on one side as a team and 10 people on the other side and the rule is that whichever side have the highest percentage of heads/tails then the 90 people flipping coins will in the vast majority totally dominate the 10 people flipping coins except if you got constant same difficulty and unlimited time then it will even out but it would take many many years if you ask me.

That is not the reason. The small pool that only has 10 people also only splits the reward 10-way instead of 90-way.

The only reason people join pools is if chance of finding a block is so far into the future that by then the difficulty could drastically change and they could mine for a month and end up with nothing.

However with the HPM I have I could discover 7 blocks/day, I don't really need a pool.

The whole logic of low hashrate pools will even out over time vs high hashrate pools is entirely flawed. This would be valid if we were talking about constant block rewards and constant same difficulty.

The fact that block rewards gets reduce quite often and difficulty fluctuate quite often effectively will keep a low hashing pool at a disadvantage and lower earnings ALLWAYS because it will have much greater variance during difficulty/block reward periods.

Low hashrate pool would need the hand of GOD to assist them if they want to actually reap the same earnings over time which realisticly just wont happen no matter how you try and slice it.

This is unfortunate though, it would be great if all hashrates were balanced among pools for equal chance of getting blocks per difficulty/blockreward period but right now with Memorycoin the competition and interest is too low to sustain a fairly equal split across all the available pools.

You are wrong, the chance is the same, this is the principle and beauty of bitcoin and memorycoin algorithm.
The only difference is the variability is much higher on small pool.
But you get more % out of one block than on big pool.

A few posts up I explained exactly what is happening and why probability slowly goes out of the window the higher the concentration of one pool to total network hashrate.

Right now mmc.1gh.com have a near 100% hitrate on all blocks and proportionally this hitrate will reflect higher than the network hashrate percentage of a smaller pool.

Hmm... I was showing 2800HPM, running 100 machines with 30HPM each showing in client. Now it's showing 1500HPM, that can't be right, I wonder if they switched to another server.
But afterwards you've disabled it manually..

Unfortunatelly you havn't found any blocks during your work, this is because there was only a few capacity at the pool. Our power was never more than 5% from the network hashrate (even with your HPMs), while the other get ca.90% and 10%.
Too high concentration of power at a pool means a negligibly small probability to find a block for the other one.

I'd suggest we three (with "MFH4DrpkfWWfFRvtdu6TJuT4D8txKAKM6b" with his 2K HPMs) try the same HPMs at the same time. The idea is, we'll be able to reach the "one-block-in-one-hour" level.

The system works correctly, I didn't change anything there, but three blocks were found for last hours. If there is a pool with a few capacities you have to look at a whole period of time -a day (with a constant speed!), but not at a stats for two-three hours.

For example, the earning coins of working hours of "MFH4DrpkfWWfFRvtdu6TJuT4D8txKAKM6b" conside with calculator.
But it works only by the same speed the whole day.

I agree, mistakes happen, and how the pool owner deals with them says the world. If anything, after this whole thing, I trust you even more now Atrides, for making everything right. Thank you.

I am hosting a mine-for-dwarfpool charity race. 

Change your miners to use maxmine.dwarfpool.com and mine for either:

MAXMinevK5EPyw2fditvrzosy9nCTR6pd1
MSmaugxBNHhpHEPJnHEzC9UsJtWyJnJxwH

First to the top of the leaderboards wins.  If Max's Mine wines, the game server may stay up for future promos.

Any funds received will be donated to dwarfpool and held below until game's end:

For quicker recovery,
I would suggest to temporarily set pool fee to 0 and somehow give additional bonus.

Security system checked and momentum-module upgraded. Fake shares not possible anymore, fake wallets disconnected,
today's payments made, recalculation for two attacking days will be tomorrow. Thanks for your understanding!

I wonder if the other pools have the same vulnerability.
No, they are not vulnerable.
they do not have such a vile "enemy". Guess why

Hey guys,

I am terribly sorry for the delay in reply, I have been just working hard on the problem..

Trankil was right
Yesterday along with an unsuccessful DDoS attacks on my servers, there was a powerful attack on the pool protocol. Our users were robbed of 3000 coins.
He sent many fake shares from several accounts (fake-shares bomb), thereby increased a part of his own shares at the expense of other users.

It must have been a person (or two?) who knows exactly about the source code of Memorycoin-wallet, source code of miners, an algorithm of Momentum with Birthday collisions on the lowest level, he found a weak point concerned with check of sheares' valiadation in source code which I based my pool on.

He quite spent a lot for attacking servers to kill our pool. I can only guess who's got the greatest profit from that..

The lying wallets are still operating, they are known but not yet blocked. All these shares won't be credited. I'm working on this.

As soon as I solve it I do public the fake wallets and allot the whole profit to real wallets (autopayment is currently frozen, the stat of "% of round" and "Amount" is currently out).
I also cover the damage from my own funds. The system itself works blameless, Let's try once again!

Thank you
