My wallet won't sync past block 15915 now.
do you have the latest wallet version? download latest one, it should work I have the latest one, It was working fine until I woke up this morning and noticed it was stuck on block 15915 Edit: I just re-downloaded the new wallet and it still didn't work. Then I deleted the blockchain and it still gets stuck at block 15915. Mine isn't syncing either. I'm stuck at block 15915 as well. Stopped about 18 hours ago, was working up until then. I hope this isn't a permanent stoppage. I have several hundred thousand coins in my wallet. And yes, I have the latest client. Yeah I hope it isn't permanent either because it wouldn't be to great to lose over a week of mining. |

wonder if the price will be pushed down lower after this rape fest.....
No rape fest as they they were not able to get many coins due to the difficulty rising quickly. You can see the hashrate getting back to normal after they gave up. No need to worry. Are you sure? It didn't go up quite as quickly as it should have to prevent the reaping. Looking at the block chain: http://explorer.karmacoin.info/chain/Karmacoin it appears you are somewhat correct. The diff didn't quite rise as fast as it could have. This is public knowledge so I feel there is nothing wrong with posting this here. My block counts per hour are (all times PST for 2/16/2014): 11 to 12 am = 59 12 to 1 pm = 211 1 to 2 pm = 190 2 to 3 pm = 102 3 to 4 pm = 6 4 to 5 pm = 9 5 to 6 pm = 11 So the average over those 7 hours is 83 blocks per hour which is above the 60 per hour ideal. Remember though that whomever put the amount of hashrate that we were seeing at this coin could have made a nice profit on at least a dozen other coins if they didn't choose Karma. The best protection from these attacks is for the price of Karma to rise so more miners are on the coin on a consistent basis to minimize the % hashrate increase. Thankfully this will average out over time and the length of the attack was very short in the grand scheme of things. If you are a consistent miner of Karma then you should see a decent average return as the diff and total network hashrate comes down. It is good to see we are making progress and I hope we have more to come. I think there is room for improvement here though. Dev's what do you have to say about optimizing the KGW to react faster to massive hashrate changes? Maybe reduce the number of blocks before re-target or change the algorithm for calculating the next black diff to better reflect total network hashrate? Vertcoin as an example seems to have a good system as the difficulty varies very little and the total network hash stays fairly high and constant. Of course Vertcoin uses N-factor Scrypt but that shouldn't make a difference in the KGW implementation. The trick with reacting faster to massive hashrate changes is if you react too fast you have the problem where a multiminer with decent hash rate can dominate miningThere are a number of coins that have just implemented KGW that still have this issue (Reddcoin was one). See https://forum.megacoin.in/index.php?topic=2791.0The exploit was they would turn on their miners for about 20 blocks, then turn them off. This caused difficulty to spike (since the reaction was quick), then drop way below where it should have been when they turned the miners off (because the algorithm tried to normalize over 14 blocks- since there was one block with a huge difficulty it drops the subsequent blocks to very low difficulties until it rises again). They turned them back on again and would take advantage of a low diff rate for about 10 blocks, at which point the difficulty came back. Meanwhile normal miners are basically blocked out by competing with a high difficulty or a huge hashrate. To immunize against this, we changed the settings to almost what Vertcoin (and several others) have, this was the update that kicked in on block 15700 Feb 15th. The difficulty does not adjust as quickly, but we are also not susceptible to the exploit. We thought about other strategies but given the popularity of the coin, did not want to risk a new algorithm which could cause destabilization. Instead we went with settings that have a good track record. As always, open to suggestions. |

In fact your actual wallet.dat file is fine. It sounds like you are just having an issue with your wallet client. Don't worry, as soon as you get it working and as long as you have a backup you are good to go |

So I got it to work. First make a back up of your wallet.dat file (If you haven't already), Then re-download the latest client just to make sure you have the right one. Then go to the "Roaming" folder (If you are using windows, if you are using mac or linux go to where ever that folder would be on that OS) and delete the whole thing. Then run the karma client and let it sync either past where it usually gets stuck or all the way doesn't matter, Then close the wallet and replace the wallet.dat that it generated with your back up and relaunch the client and it should be fixed. |

In roughly 5 days mining block reward will decline from 1.5 million to 1 million. If the site launches in roughly the same time, it will be a nice double punch.

I agree they are a blight on the crypto world but according to my calculations they only could have made 11 BTC worth if they mined every block during the attack period and that is if they sold them all at 3 sats. I am sure they didn't get every block. Still they didn't help and we are all glad it was short. |

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...

best way to solve this problem is set exact block value (750k), because in crypto is not random really random. You can know block value in the future. people abuse it at doge, they will abuse it at karma too. Random block value is most stupid thing ever.
