last time i saw something similar to this was with Metisicoin ( MTC now MTS ) , where ypool went offline and now one could sync until the ypool wallet came back online.

Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

notice vertcoin also Algorithm: Scrypt-Jane Proof-Of-Work with modified nFactor *[WARNING]: Pools with this symbol are at or over 33% network hash. mining on the largest pool can cause problems with the coin. Please choose one of the smaller pools. The smaller pools are automatically moved to the top of the list every 3 minutes. not just notice problem coin or problem algorithm mrc.blocksolved.com or other pool > ~60%

We are still investigating the stuck block. The problem is not with the wallet version, so using an older wallet will not help.
Do not try to transfer microCoins. They'll only get stuck.
If you believe you know what the problem is, please contact us. We can even agree on a bounty if you can fix the issue before us.

Error from my daemon log:
keypool return 104393 ERROR: AddToBlockIndex() : Rejected by stake modifier checkpoint height=124000, modifier=0xa4251ce5b54ee576 ERROR: AcceptBlock() : AddToBlockIndex failed ERROR: ProcessBlock() : AcceptBlock FAILED

// Hard checkpoints of stake modifiers to ensure they are deterministic static std::map<int, unsigned int> mapStakeModifierCheckpoints = boost::assign::map_list_of ( 0, 0x0e00670bu ) ( 124000, 0xe791f02cu ) ;
It looks like block 124000 is looking for 0xa4251ce5b54ee576 but got 0xe791f02cu in checkpoints array.

Maybe too big block - very large transaction or many very small inputs edit: can also be magic number

Was there maybe an NFactor change that could have screwed it up?

Please don't sell your coin at poloniex because of the bug In coming crash is imminent, alt coin miners are hard convinced, especially since most of them are flash miners that don't support any coin and just looking to make a profit.

It looks like block 124000 is looking for 0xa4251ce5b54ee576 but got 0xe791f02cu in checkpoints array.
I was also looking into this ... My understanding is that the second checkpoint (124000) should not be set at all yet. It was most probably in the coin MRC was cloned from, because this coin already went over block 124000. But the value is probably valid for this coin blockchain, not for MRC. Anyone can confirm ? EDIT1: anyway, it clearly is not required also because proof-of-stake is not enabled yet in MRC ... it should kick in only after one full year (60*60*24*365 seconds, as stated in main.cpp) EDIT2: the 124000 value does not come from the PPC code (they have other checkpoints for the proof of stake, but not this one). From which coin was MRC cloned ? This value most probably comes from that ancestor.

I'll be selling as soon as I'm able. Price on Mintpal is going up, hopefully they won't realise there was a problem

(will look into the PPC code in the meantime) Google found the same line from TIX source, so this is probably the cause. https://github.com/LotteryTickets/LotteryTickets/blob/master/src/kernel.cpp

I'll be selling as soon as I'm able. Price on Mintpal is going up, hopefully they won't realise there was a problem Do not sell:) MRC will be just like Mintcoin price soon. Bug will be fixed. Do not get FUD in your mind. Stay calm and stay tuned, hold and wait few days, better sell at 10-12 than sell at 5

From which coin was MRC cloned ? This value most probably comes from that ancestor. MRC comes from TIX. We have found the proof-of-stake checkpoint and removed it. We now face the problem of testing if the problem is fixed or not. This should create a hardfork, but fortunately the fork the older client is on should never be able to go past block 123,999. Does anyone have any suggestions? We are considering putting the wallet for download and getting pools to use it and see if it works.
