Quote from: wdl1908 on May 16, 2015, 12:23:32 PM The wallet is locking up on that error now every few minutes. Was there not a patch available to solve the time warp attack? Code: 2015-05-16 12:17:39 CheckForkWarningConditions: Warning: Large valid fork found forking the chain at height 3500386 (02c5ed03a36b76ce56fe746c047f2ce7592645d7265224ae67f2579d41eee8dc) lasting to height 3500394 (1949114e98e794fb0947154b3057ac61c9727c1e783e7f5397cb0b3efb0ed84d). Chain state database corruption likely. So this is what is happening now it happened 2 times already. Yes, there is a patch. But any fix would create a fork of the blockchain. All old clients would be mining the old chain and all new clients the new one. A fork like this can only work if everyone is upgrading to the new version. The best way to do it would be to remove the KGW at a block somewhere in the future and spread the new client to everyone. By the time the block is reached everyone must have upgraded! I could do that tomorrow. But I need to know how far in the future the "block of change" should be What do you think? And I need some support in telling the major "Krugercoin-players" to upgrade Nibiru seems to have vanished and he owns the Krugercoin Website.

Quote from: wdl1908 on May 16, 2015, 06:59:42 AM I've check the block explorer and it seems every few blocks there is a fork. I checked through the debug log and there is a rollback of sometimes 2 blocks on another fork. it's very strange I have not seen this before on any other blockchain. Yes, I see it too. My guess is someone is attacking the chain. I know the Kimoto Gravity Well is vulnerable to the timewarp attack. I guess I'll have to remove it. But then everyone will have to upgrade to the new client.

And now this.....

Code:

{
    "version" : 90300,
    "protocolversion" : 70002,
    "walletversion" : 60000,
    "balance" : 1487.18640000,
    "blocks" : 3499062,
    "timeoffset" : -1,
    "connections" : 12,
    "proxy" : "",
    "difficulty" : 0.20412772,
    "testnet" : false,
    "keypoololdest" : 1405392075,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "relayfee" : 0.00001000,
    "errors" : "Warning: The network does not appear to fully agree! Some miners appear to be experiencing issues."
}

I did not see the error message last time but it noticed something was very wrong and restarted the daemon.

same here. Maybe someone is attacking the coin via timewarp. I think I will have to implement a protection against that. But that would mean old clients would be on another blockchain and wouldn't be able to connect to the new clients anymore.

By the way. Cryptsy wrote back:

Quote from: wdl1908 on May 14, 2015, 09:10:48 PM I think the blockchain forked again. The blockexplorer at http://kgc.blockexp.info is the same as my wallet but all sends to cryptsy don't arrive and the diff is 0.02 normally it's around 0.25. So how do I get back on the correct fork? KGC-blockchain seems fine. My deposit to cryptsy isn't showing up too. So I think it's a problem with cryptsy. I opened a ticket at their support site. If you can tell me your transaction-ID I can add that to my support request.

It is actively mined. Currently at above 130 Megahashes per second. Difficulty is at 0.46. Price at Cryptsy at 0.00000015 BTC per KGC. 24 hour volume at 0.021 BTC. So it's not dead yet ;-)
