IMHO it look like logo for infants. I thought after first look it is some seal.

yes it does look childish but don't forget how successful Doge was by looking utterly comical.

you know if this coin was used in schools to teach children about new forms of money, used for school fundraisers or even used as rewards for good grades (like those smiley stamps we all used to get) then this could really take off..

don't forget that ALL of us whether young or old use smileys nowdays...  Wink and that is an example of how something infantile can become ubiquitous...



what happen with DOGE was totally rare and will not happen again. You can use any coin for any purpose. Change wallet, name and logo is pretty simple. We mining numbers, everyone buying it and mine it just for personal profit. But it logo in pretty symbolic : a new elephant is born from giant vagina, head is almost out -  beginning of the new coin Cheesy

when I seen KARMA first time I like its logo.. let it be. Can you imagine this logo at Lamborghini? No because nobody want BABY elephant car. It is cute, but not good for serious product. This coin need simple and more mature logo. Give it time..

Realistic: 20. When hyped: spikes to 50-60, then stable at around  30 - I guess. But AS always: just my 2 Satoshis. Don't listen to me - make your own picture/decisions!
AMEN!

but I do not think it will climb to 8 today.

6 and 7 sat is still very cheap... imho
if you want to sell big amount of KARM and want to make BIG profit -YES, it is cheap.

those buy and sell walls holding the coin between 3-4 sat really need to be removed.....

if someone decide to buy karma, no wall can stop him. Is a huge wall sell wat at 4 sat? no problem.. someone just will buy cheap. If someone want to buy some karma, why push him to 5+ satoshi if he could buy at 4 or less. If is 4-3 sat good enough for sellers, it is ok. I think price can go slightly down when difficulty do not raise after fork. Because with 40 diff 760k karm per block and 3 sat buy it will be the most profitable coin. Lets hope more people will join to mine it. When diff will fall to 20 again, we will get coins almost for free, so everyone will dump it at 3 sat.

The best thing on KARMA coin s that devs care about coin. Many others coins are just forgotten by devs. Lets hope this is the last big change.

有中文说明吗?

Does this coin provide new innovative features that are coming out with new coins like built in coin mixing technology? Scrypt is a faulty legacy algo that makes your gpu run very hot. The new algos make gpus run 30% coolers, use over 20% less electricity and increase hash rate by 500-1000%. I am hashing at over 7megahash a second with a couple of r9 290x with 20 intensity and running STEADY at 68c with 1900 rpm fan speed. Sorry to say that any coin that still uses scrypt is going to die to the new breeds of innovative coins that actually provide something useful to the crypto community besides a new catchy name and a cute logo. Sorry to tell everyone "mooncoin" is not professional and will never be taken seriously in a corporate sense. Sure they're fun for 13 year old to swap each other moon, doge, and fairycoins but they are a joke to the cryptocurrency movement. Anyone holding these types of coins aren't thinking "I can't wait to be able to buy a house with mooncoins" they are thinking "can't wait for mooncoin to spike so i can dump them and buy a coin actually worth something".
tell me more in PM what algo you use. I do not know nothing about other algo except SHA256 and scrypt

From the Devs:

Here is what we know:

- There is a private pool with significant 1GH hash power (about 1400 GPU cards) who has been consistently mining this coin from the beginning
- Right now pool.karmacoin.info and hashstrke.com make up 1.5GH, the private pool makes up 1GH to get us to 2.5 for the whole network
- Rewards are going to change in 3-4 days and we have other launches happening with the first version of the updated site coming at the same time.  The value will go up when that happens so someone right now would be motivated to try to drop the value in order to buy it cheap.

we do not need to trolling.. it is just facts.

Right now pool.karmacoin.info and hashstrke.com make up 1.5GH, the private pool makes up 1GH
how much Ghs has these two sites  more than 2 days ago? Was 51% attack possible? Because it will explain a lot.

I just ask, why people at pools have less rewards as expected. One day ago I was count last 20 blocks at pool.karmacoin.info and average reward was about 350 000KARM instead at least 500 000 (ideal is 755 000) (I am not remember exact numbers.. it was write in this thread). I am with KARMA from day one, and I want to some profit of course, so I am just asking , why you do not set fix reward system. Everyone must noticed that he have less karmacoins as expected. Just watch your hasharate, difficulty and expected rewards at last one day.

and now it is show in coinwarz as most profitable coin. So many people start to mine it, but they will mine just about 1/2 of that amount, maybe less. They will be angry. Or maybe 51% attacker will loose his power, witch will be good.
92  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][KARM] Karmacoin - 6 Exchanges - Most Profitable 11 Days Straight on: February 19, 2014, 10:47:04 AM
I was mined about one day with 5200ksh and all I get is 826 000KAR instead 3-4M. diff was 20 max 25 sometime. It is not normal.

YOU DO NOT HAVE TO BE GENIUS TO SEE THE SCAM WITH THE REWARDS. FIX IT OR THE PYRAMID WILL COLLAPSE MY FRIENDS.

maybe it is not a scam from devs side, but only abuse of the wrong set system. And maybe someone own 51% of the network. Dogecoin have huge network, it is hardly possible to make 51% attack. Dogecoin rewards is lesser too, just because big players mining only most profitable blocks. If you can rewards for next block, it is easy aim your rigs just for the most profitable blocks. And who will mine blocks up to 200k? We do it. Big ones just aim their rigs to another coin until next block will be profitable for them. This random reward system is just BAD.

"The pattern is clear: the network is finding high-value blocks significantly faster than low-value blocks. Low-value rounds take as much as 10% longer than intended, and high-value rounds take around 5% less time than intended. Significant hashrate belongs to miners that cheat."

Karmacoin continues to explode!  In the past 24 hours we have had more than 140BTC in trading on our coin.  In addition, the rewards generated by miners will be drop from 1.5M max to 1M max per block in 3-4 days.

It is still the most profitable coin listed on altcoinstats.com, and is in the top 25 most traded coins in the alt-currency world.

We are a few days from launching the newly designed web site, we will post more information as we approach the date.

Thanks for the community and the great support from every one!!

sorry, but I must just say "BULLSHIT" . Maybe you are blind BTCBTC , but we all see that biggest block rewards someone manipulating. It will explode.. you have right. Can you explain why at average diff 25 we got just average 450000KARMA per block instead 755000? I have 5200khs rig and I can mine just about 1,2M per day instead 3M+ . It is NOT luck factor.. it is SCAM.

I do not know, if is karma in trouble, dogecoin and lot of coins have the same issue, but it is not fair at all. If it is not truly random, it is better to mine fixed value. But it is only my opinion. Because if I expecting daily reward 4M and I will receive 1,4M, it is weird. Random block in the dogecoin was because doge was made as a fun coin.

I have noticed the same.. I can set set my miners and end up with actual result about 75% lower than the expected amount. This is also from constant KGW diff fluctuations, not only because of random block reward.

What is the reasoning behind having random block reward anyway? Is it just to add some element of lotto,gambling,randomness to the coin? It doesn't fit the theme of the coin and if it can be abused it needs to be removed or modified fast.


I have not problem with random rewards, but this "random" is just predictable. So it is not random. And if it is not random it can be abused. And it is. Every time when doge will have high reward block, network hashrate increase and then drop. Just because for someone is better to mine only if he have chance for BIG rewards. I think it is the same in karmacoin. And it is unfair for common people like we are. I just think, that serious coin can not have random reward. If someone here have 51% net hashrate, he can easy mine his own way an if you will find 1,5M block and he too, he just can drop your block to trash because he have 51% of hashrate. That can explain his 1M+ rewards.

Please do your research, I did.

Last 24 hour average block size for pools: From 8 pm 2/16/14 to 8 pm 2/17/14 (PST timezone)

karma.hashstrike.com = 247 blocks/448009.8825910931 avg

http://pool.karmacoin.info = 237 blocks/456402.3839662447 avg

http://karm.idcray.com = 103 blocks/717014.3203883495 avg

For a total average of 587 blocks/498600.1379897785 avg

That is where the hell my claim comes from. I don't want to argue but please research first. This is way out of the range of luck isn't it? The attacker is getting massive block sizes somehow compared to the pools.


Well, I think I figured it out, and there's basically nothing that could be done besides changing the block rewards to a static value.  I talked to someone with good knowledge of the dogecoin source code (which karmacoin was based off of) and, well, here you go...

Code:
00:39 < trigeek> the random seed for block rewards
00:39 < trigeek> it's solely derived from the previous block hash, yes?
00:39 < xxxxxxx> its not as random as you think it is ;)
00:39 < xxxxxxx> yup
00:39 < trigeek> well it can't be that random
00:39 < trigeek> otherwise nobody could agree on it
00:39 < xxxxxxx> yup
00:39 < xxxxxxx> there was some nifty bit of research done
00:40 < trigeek> so, you can determine what the next block's reward is, correct?
00:40 < xxxxxxx> yup
00:40 < trigeek> ok. thats what i thought
00:40 < xxxxxxx> there was the cool bit of code that could let a multipool know if the next payout was gonna be a X block
00:40 < xxxxxxx> like "oh the payout's gonna be 2" fuck that
00:40 < trigeek> that's that, then.

TL;DR - the multi-pool is switching their hash rate on and off based on what the reward of the next expected block is.

I wrote it here https://bitcointalk.org/index.php?topic=447657.msg5201798#msg5201798

If devs do not remove random reward soon, it will be worst. Because "chosen ones" abuse this "bug"



Is karma in trouble?

I've a question.

Look's like a large private pool is connected to network...
At this time is 1400Mhs network hashrate.
pool.karmacoin.info - 387Mhs
karma.hashstrike.com - 296Mhs
other officially announced at start page ~ 10-20Mhs
Black hole: ~700Mhs
Next.
Block 17840-17845 generated by K7SBPBYDkEPpDqpARgE9xBes7f1FZ6w68Z with total amount of 4869397,001 KARMAs. 811566,1668 average per block. Higher than other pools... Ok...

Some investigations in block explorer...
http://explorer.karmacoin.info/tx/d02563e283e1b438b9d02c19bddcad584fd661384b8346bea625f41df3f936fe
K7SBPBYDkEPpDqpARgE9xBes7f1FZ6w68Z sent appx 27517929.016 to KUMpz7KSH2ym3XVDFws3YhqapcA26JdQW5
Ok...

Sent, sent and sent...
And voila:
Code:
Address KUMpz7KSH2ym3XVDFws3YhqapcA26JdQW5
Details
Balance 2589363996.56565243 KAR
Transactions in 742

Transactions out 336
Sent 4365753380.65792523 KAR
omg... 2.6 billion... 77btc at 3e-8...

And yes, only K7SBPBYDkEPpDqpARgE9xBes7f1FZ6w68Z sent to KUMpz7KSH2ym3XVDFws3YhqapcA26JdQW5.

May be I'm wrong, but...

And now my question: is it possible 51% attack at KARMA network?

add/
From block 18100 to 18143 all blocks with reward > 1mio except one was generated by K7SBPBYDkEPpDqpARgE9xBes7f1FZ6w68Z, and smallest reward was appx 0.65mio.
So lucky )))

That worries me a lot. Someone could enlighten us?

lol that address almost has 16% of all KARM in existence on it lol

Feels like the devs knew the algo and how to highly increase the chances of getting the bonus rewards, or that someone found a way to do so. If it's the devs, it starts to make sense as to why the bonus rewards are so high..



I think dev needs some explaining to do here.

This wouldn't surprise me if it was true.




The algorithm is right there in the source code:

Code:
int static generateMTRandom(unsigned int s, int range)
{
        random::mt19937 gen(s);
    random::uniform_int_distribution<> dist(1, range);
    return dist(gen);
}

...

        if (maxRand != 0) {
                double rand = generateMTRandom(seed, maxRand);
                bonus = rand * COIN;
        }

        return nSubsidy + bonus + nFees;

It's a standard random number generator.  They just got lucky with those blocks.  As for the devs being involved with that miner.. they're not.  I've spoken privately with them about it and they don't know who it is.  There's no way to tell who it is, but it's clearly someone who saw a huge opportunity with karmacoin.  That 700MH has been there for a LONG time now, and it has STAYED on almost the whole time.  They could be mining a lot of other coins with that hash rate, but they're mining karma.

I certainly hope they don't dump all those coin at once, because it would decimate the market... but I think they're smarter than that.  If they have 70BTC+ worth at 3 satoshi, they have to be thinking about what is going to happen if it hits some real exchanges.


It is not the definitely not the dev (my team)!  The person (group, multiminer, etc) who has been mining it has a farm with between 700MH to 1GH, and they have been mining it consistently.  That is upwards of $1M USD in equipment with an enormous electric bill (probably 40-50K USD).  I am basing those estimates on what I pay for 2MH but it should be close.  They definitely see a big upside to the coin and the community, as we do as well. Given their scale I don't see why this person would sell now or sell in a hurry (i.e. there is no way they are hurting for cash if they had enough to buy 1M of equipment).

As far as the code and the algorithm, there isn't a way to game it to get more lucky.  The source code is here at https://github.com/karmacoin-team/karmacoin, the file that has the algorithm is src/main.cpp.  Also the algorithm is pretty much the same as used by DOGE for the randomness so it's been beat up and proven over the past several months of their existence.



http://explorer.karmacoin.info/address/KUMpz7KSH2ym3XVDFws3YhqapcA26JdQW5   shows over 7 billion coins recieved and over 4 billion coins sent. i would believe this coin is an exchange. possibly coinmarket wallet address where all of us sent out coins to them.

What is strange about this is that K7SBPBYDkEPpDqpARgE9xBes7f1FZ6w68Z this address keeps sending out the coins to KUMpz7KSH2ym3XVDFws3YhqapcA26JdQW5


we need to figure out what the hell is going on.
It's obvious it's an exchange wallet.

We don't really need to figure out much. There is a big miner making money. Same as the little miners. He just has a lot. Too bad for you

Too bad for us all as they are tanking the price. They don't care about the coin just about making money to pay for their massive equipment and power bills. Not sure whether we should be flattered they chose Karmacoin or afraid of what's to come. There seems to be buyers at a price that makes it profitable to mine so that is a big plus...even at the rate we are creating new coins (which is very high right now).

If they are sending most of the coins to an exchange to sell then that may help to explain the massive sell positions at the 3,4,and 5 sat levels on all the exchanges. I am more concerned about what seems to be unfair average block rewards for them. Why are the seeing over 800,000 coins per block when all the pools are only seeing less than 500,000 coins per block over the last 24 hours. This to me is hard to explain with just luck and randomness. Dev's please explain how this can be? Almost double the payout per block is way out of the range of pure luck. Especially spread out over 24 hours. This is very disconcerting. It is bad enough they are getting all the blocks but getting all the good blocks as well is too much.  
There is nothing wrong with mining the most profitable coin. It means equilibrium isn't reached. It's all a natural process at this point.

And I don't know where the hell your claim about the block rewards inequity comes from. Looking at the top 3 pools blocks found, only a very few are under 500k.

Please do your research, I did.

Last 24 hour average block size for pools: From 8 pm 2/16/14 to 8 pm 2/17/14 (PST timezone)

karma.hashstrike.com = 247 blocks/448009.8825910931 avg

http://pool.karmacoin.info =

No luck at all I think. If you have big hash power, and you know witch block is worth to mine, you just point your power on the network at the right time. And look, 1M+ blocks. Or he can do 51% attack. I do not think Karma is most profitable. I have 5khs rig and I have barely 1,5M karma per day. because common pools mine just shitty amount blocks like is written above. Something fishy is about this coin. And worst is I believed a lot this coin.

No , its' because people are afraid the coin is on life support and might get delisted soon. So they will end up with 0 instead of one satoshi.

Wait ! You haven't seen a coin with 0 value? Or you don't think that's possible :? =)))))))))))))
they still can sold it for litecoin, or doge.. 0 satoshi is not dead coin Cheesy If someone worried about this coin, why they mine it? How many CAGE can I mine with 5000khs/24. IMHO this is first coin I have seen with 0 value Cheesy And first one I was bought for 1sat Cheesy
