Obviously if the super pool is only mining high value blocks it will only find high value blocks. But even still, wouldn't the pools that are on the coin 100% of the time still get an average amount of high value blocks along with all the low value blocks? Seems like the pools mining normally do not get the correct amount of high value blocks.

So, based on estimates- it seems as though the "mystery pool" is about 700MH or so, which is a decent amount.  Before yesterday, the net hash rate was somewhere around 2.5GH or 2500 MH.  When the mystery pool is on the network, that means that they have a 28% chance of finding one of those big blocks, and the rest of the network has a 72% chance.  However when they decide to sit out a round, we have a 100% chance of finding those smaller blocks, and they have a 0% chance.  This means that our average block reward  overall is lower, because we have a better chance at finding the smaller blocks.

Here's the thing though.  When they drop off the network, you know what else drops? The difficulty.  It reduces some of the damage done, because even though we're finding smaller blocks... we get to find MORE of them.  Here are what our numbers look like over the past few days:

Code:
+------------+--------+-----------+----------+
| date       | min    | max       | avg      |
+------------+--------+-----------+----------+
| 2014-02-17 | 12,423 | 1,393,339 |  436,665 |
| 2014-02-18 | 15,009 | 1,463,166 |  446,819 |
| 2014-02-19 | 12,627 | 1,205,115 |  494,429 |
+------------+--------+-----------+----------+

We're still finding big blocks.  We just have a slightly lower chance of finding them, like a 28% lower chance with the current net hash rate.  If the net hash rate were to hit 7GH, that chance would drop to 10% lower, and if it were 14 GH it would only be a 5% difference- negligible.  That's why nobody even notices with DogeCoin, because the net hash rate is so huge that it would be impossible for someone to get a lot of the big blocks.  They can still decide that they only want to TRY for big blocks, but that doesn't mean they'll always get them.

CACHe coin is more profitable to mine in recent condition. Al;l other coins are giving back very less profit.
In CACHe coin still can make $100+ with 2.5 Mhs

CACHe coin? can you send me a link to that coins ann?

Yes ladies and gentlemen that means that the exploiters are getting over twice the number of coins per block as the top two pools combined over the last 24 hours. HOW IS THIS POSSIBLE IN A FAIR COIN? The profitability calculators for this coin are way off and should be cut in half to get the correct numbers for us miners. The trade volume is dominated by the exploiters who artificially inflate the coin to make it look attractive. You my friends are the patsies in this scheme.

Thanks for a math, I've stopped mining this coin until devs fix this issue. I'm not very happy to loose my haspower on such scam reward scheme.
and yes, this makes BAD KARMA to all who cheats us.

Why is random not random and calculated from last block(s) ?

If random was really random, that would mean that I could always submit blocks that were the maximum value and just tell everyone I'm honest and that I really did "randomly" find a block of 1,499,999 coins.  It has to be a random number that everyone agrees on and trusts, so the randomness is based off of the hash of the previous block found.  Here's how it works.

1. Each block has a "blockhash", which is a long string like this: 6da0c15336ce5ab8bfd42473bb305743ba22ec86f0f8b6fa184b33a69df30acd
2. That string is converted to an integer, and used as a seed for the random number generator.  Every random number generator has to have a starting value, and given the same starting value it will always produce the same sequence of random numbers.
3. The random number generator picks the value of the next block.

This means that everyone on the network can check the work to make sure that the person who submitted the block isn't lying about the value of that block.  The downside to this is that it means that you know how much the next block will be worth, BEFORE it is even generated.

Obviously if the super pool is only mining high value blocks it will only find high value blocks. But even still, wouldn't the pools that are on the coin 100% of the time still get an average amount of high value blocks along with all the low value blocks?

Is it possible to program true random block with crypto that is also secure from people submitting false block claims ?

I've been picking my brain trying to think of another way to design it, and I haven't come up with anything.  Every block that gets added to a block chain has to be in some way based on the previous block, and you have to be able to re-construct it after the fact.  It's a chicken and egg problem.  With random blocks, it would be great if you couldn't predict the next block.  But you HAVE to be able to predict it, because the value has to be set before the block is created.  The value of the block becomes part of the block hash, so it can't be set afterwards.  It's a chicken and egg problem.

It's just fundamental to the design of random reward blocks.  But AGAIN- there are successful coins out there with random rewards!  I keep coming back to it, but DogeCoin has this same "flaw" because it uses the EXACT same code.  So if karmacoin is "screwed" because of this, so is DogeCoin.

    ATTENTION EVERYONE WHO MINES OR BUYS KARMACOIN!!!

Re-posting for those who may have missed. All the pools and regular miners getting massively ripped off on the block rewards right now. This is blatant and obvious to anyone who cares to look at the publicly available numbers. There is no other explanation for what is happening. I am not going to try to tell anyone what to do but you look at the numbers and make your own decisions.

Last 24 hours of blocks found. Time period 4 pm on 2/17/2014 to 4 pm 2/18/2014 (PST timezone)

The two biggest pools for Karmacoin

http://karma.hashstrike.com = 230 blocks and 98155792.429 coins mined for an average block size of 426764

http://pool.karmacoin.info = 369 blocks and 163830536.742 coins mined for an average block size of 443905

Total blocks mined during this 24 hour period by everyone (numbers from the blockchain site) = 1411

Total number of coins mined with these 1411 blocks = 1082426659

Remove the coins and block mined by these two pools and you have the following:

1411 - (230 + 369) = 812 blocks by others

1082426659 - (98155792 + 163830536) = 820440331 coins mined by others

So then 820440331 / 812 = 1010394.496305419 average coins per block.

Yes ladies and gentlemen that means that the exploiters are getting over twice the number of coins per block as the top two pools combined over the last 24 hours. HOW IS THIS POSSIBLE IN A FAIR COIN? The profitability calculators for this coin are way off and should be cut in half to get the correct numbers for us miners. The trade volume is dominated by the exploiters who artificially inflate the coin to make it look attractive. You my friends are the patsies in this scheme.

These numbers do not lie. There is no way this is pure luck. In fact they tell us a truth that someone has found a massive exploit of the code behind Karmacoin and is using it in our face without any fear of being caught. They do not care

This can only be fixed by changing to a fixed reward amount. The problem has been brought up with other coins and is a known exploit. The devs are dragging their feet here and need to act fast to fix what they have themselves acknowledged to be a serious problem.

The best thing you can do right now is spread the word about this far and wide so that all miners know to steer clear of Karmacoin until this is fixed. As for what you decide to do with your own hashing power and hard earned cash I will leave up to you but I am not touching this coin with a ten foot pole. Good luck to you all.


this 'karma'coin reeks of bad mu-mu.

If you think it sucks so much, why are you still here? Oh wait, I don't care.

I urge everyone to locate the "ignore" button next to his name, it will increase your inner peace and lead to greater karma all around.  It's working for me already.


Then how did you see what I wrote? Yea ignore the issues instead of dealing with them. Are you an alcoholic? I'm here to bring enlightenment to the fact this coin is complete scam trash. Basically I'm collecting REAL LIFE karma.

No, it's simply a matter of maths... You have to know or be able to calculate how much a block is worth. It's a bad idea to do that based on the hash of the block itself, because then people keep mining until they've found a profitable hash. So you decide in advance. Some coins predetermine the value, so blocks with a prime number are worth 2x normal, or block 10k gets you 100x normal. Here it's based on the previous one, which introduces some randomness. Disagree? Bad luck!
