@Dev
could you upload another Blockchain.bin for Windows, because I'm not compatible with mega. always stuck at 97%
Here's new link to Blockchain.bin for Win 64 |

So if you have a bunch of small transactions and want to combine those into a larger single block, the general idea is that you send your own address a transaction (more or less of maximum size), right? And you repeat this until you have your coins more or less combined into a larger block that can be transmitted? I'm trying to do this but running into problems. I did the following: transfer 0 [my address] [amount] The initial amounts I tried resulted in a transaction that was too large, so I had to try again (and again) until eventually I managed to send a transaction of 1.4 QCN. Woohoo! I then continued sending another small transactions every few minutes until I reached the point where my balance of QCN was exhausted. But then I discovered that all that work was apparently for naught -- most of the transactions failed to get written to the block chain. What's going on!? Best guess: my transactions are being ignored by the block finders because they are large and small -- meaning, maximum size but minimal value in coins. Is this reasonable? I had this happen once already when I tried to transfer coins to Poloniex -- only one of seven transactions actually showed up. I had to delete wallet.bin and then resync the wallet, at which point all of the "lost" coins reappeared in my wallet. Then I did the above sending coins to myself to try and group them into larger units, so I could send a single transaction to Poloniex, and of the transactions I sent yesterday it seems only one of those went through. Has anyone else experienced this? Is there a solution/workaround that I'm not doing properly? It looks like my initial mining of QCN generated 2781 transactions totaling just 10.4 QCN (give or take), and you can only have about 100 inputs into a transaction before it becomes too large. So I wanted to send myself 28 transactions, basically, and then I could send myself one "big" transaction, and then I would be done. But it's not working that way. :-( Also, I'm now getting the following after "resyncing" with the chain: 2014-Jun-26 18:30:28.370301 [RPC1]ERROR ..\..\src\cryptonote_core\tx_pool.cpp:62 Transaction with id= <d27babecc9557afef79f440f5ab140a7fd2340f9849c703aeda1aec22c4f7e3a> used already spent key images

This is seriously a pain in the butt! The wallet needs some help if QCN (and other CryptoNote coins that are similar) want a chance to succeed!

You was absolutely right when sent transaction for yourself. I recommend to have at least 2 wallet: for small transfers & pool payments and for large transactions. After this your transactions got into the tx pool. It means the network see it, and you can't spend these quazarcoins but hash wasn't found in block explorer. You need to wait a while. If after 24 hours the transaction didn't deliver, QCN back in your wallet. |

Course, I periodically check other CN GitHubs. The BCN devs have uploaded an updated high-level API and now I'm carrying out research. It has some hardcore things and this makes it so interesting. Also I prepare a big update and probably will use some ready-made solutions. |

Can anyone explain how the hell can I spend these fucking coins mined at Minergate?  Every time I send them somewhere I got them back one minute later. It seem to me that you send QCN to yourself  Check QCN address of exchange. |

And as this is a separate discussion, it would be great if we had additional checkpointing going on. It looks like there's a checkpoint at around block 14500, give or take, but that's the last one. So when you resync the wallet, it's really fast up to block 14K, and then it takes much longer to finish the second half of the block chain sync.
Checkpoints don't affect the simplewallet work. |

Running newest 64 bit windows daemon and wallet (as linked in the first post). Removed wallet.bin and restarted again. Plenty of time allowed for sync. Still failing, daemon output: 014-Jun-30 11:47:59.995676 [RPC0]ERROR ..\..\src\cryptonote_core\tx_pool.cpp:62

[wallet 1NpViU]: I tried using a new transaction ID, but error is still the same. I've seen the 'used already spent key images' message before I'm sure. Are you sure that the daemon was synchronized? Did you see a green notice 'Synchronize OK? |

can someone pls tell me which files are necessary and is there some way to retrieve the coins?
Only *.keys file is necessary. It's your private keys, backup it. I posted a lot of times. Wallet.bin is just a cache and it will be recreated again if you run simplewallet --wallet-file wallet.bin again from wallet.bin.keys. That is what I have done 10 times+ so far. The problem persits. I can resync the wallet but the wallet is unuseable, it closes itself after it resyncd. (meanwhile I cant type any commands) The cache file is named QCN instead of QCN.bin. My wallet is named, QCN wallet.bin but only a QCN (file without fileformat) is created. my keys are: QCN.keys shouldnt it be named QCN wallet.bin.keys  So my files after the resync of the wallet are: QCN QCN.keys while it should be: QCN wallet.bin QCN wallet.bin.keys shouldnt it? This is the batfile with which i created the wallet 10 days+ ago: simplewallet --generate-new-wallet=QCN wallet.bin --pass=blabla This is the batfile to access the wallet: simplewallet --wallet-file=QCN wallet.bin --pass=blablabla It worked flawlessly for a week besides the common dust problem. As stated later the very first deamon and simplewallet works with my files. However I am unable to send any coins anywhere. WITH ANY NEW RELEASE MY SIMPLEWALLET CLOSES ITSELF EVERYTIME. Yes I deleted the .bin files and the whole %appdata% quazarcoin folder and resynced everything and dozen times. BUT ONLY THE VERY FIRST REALEASE LETS ME USE MY SIMPLEWALLET. The wallet has atm ~ 180 qcn in it which I would like to transfer to a new wallet. But this seems like an impossible task. @ Dev, can I send you my .keys file and can you look into it? As a side note: I have set up 2 new wallets with the newest client files which work just fine. If you've not resolved this problem, PM me please. |

I just added Desktop Notifications to HashInvest QuazarCoin pool, if you wanna be notified when new block is found on pool, enable desktop notifications for *.hashinvest.net. Point your miners to http://qcn.hashinvest.net & Happy mining! Great! The pool devs are very active lately. |

nice! holding to every single Quazar like there is no tomorrow, thank you for sticking around dev! I checked top performing cryptonotes and unless you have serious cloud/rig CPU farm.. difficulty is just so high.. and it doesn't stop every mined coin is like gold Thanks |

I wrote. And I must say yesterday I & sammy007 found that the formula on this site isn't quite correct. |

Hi there, I added simple estimated coins per day calculator to QCN HashInvest pool. Results are different than on http://whatmine.com. Thanks, dev, for formula. Poke me a better formula if you are good in alchemy.  Good job, thanks. I added this link to services. Usually I check it here - http://whatmine.com/  Nice profitability  |
