If you have tried reinstalling several times, a reboot might help. However, this may also be a hardware problem. It is possible that the sudden power outage caused some issues with your computer. For example, sudden power loss to a HDD can cause the reader head to crash into the disks and cause them to be damaged. Try installing a different wallet software and import your private keys from your wallet backup.

That seems odd. Maybe it is a corrupted installation. Try reinstalling it again. Make sure you delete the bitcoin datadir before reinstalling. Also backup your wallet.dat file.

Also it seems like your blockchain data is corrupted (because of powercut), There're 2 things that you can try;
1- start bitcoin core wallet with -rescan parameter. If it doesn't work then;
2- clean the blockchain's folder (don't forget to copy wallet.dat to another location) and resync with the network.
He has essentially done these by reinstalling core. bobby88 - what happens when you run core? Is there any error message on the screen? |

put it in code brackets. Click the "#" button and put the data in there.
|
|
|
|

Is there any error message when you try to start bitcoin core? Can you post the your debug.log? The file should be in C:\Users\YourUsername\AppData\Roaming\Bitcoin if you didn't change the datadir location.

Get a UPS (uninterruptible power supply). When the power goes out, it should provide enough power to safely shut everything down.

I usually trust people who post have open source code with decent documentation in the code. I also trust people who have trust or aren't newbies whose first post is trying to get his work out. I suppose obfuscation is okay, as long as the code is open source.

can you please, if you dont mind get a little more in depth with blocks and genesis.
basically genesis is like the tip of the pyramid?? like everything will continue to expand from this first point, am i getting it right?
yes. how do i make a genesis block?
I'm not sure how to make a genesis block for a new altcoin, but I do know that on a private Regtest Bitcoin network, the block is created by this command: the reason i am asking all these is, i feel that, the best way to learn how mining and everything about the crypto work, is by able to have my own coin. that way i would learn how to do my coin, compile, learn the linux and everything about it. i have time, i can spend lots of time understanding and digging in. i dont use linux and my knowledge on linux is euh.... lets not talk about it  i think i will opt for the x11, but i dont want to make it work like btc, have to wait 1hour before all confirmations and stuff. it has to be instant. split seconds Confirmation times do not have anything to do with the algorithm. For instant confirmation times, you will need to change in the code the target time between blocks and the difficulty re-target time. |

Does anything happen if you just run bitcoin core 0.10.0 for a while? If it doesn't give you an error message, then it should be syncing up fine. You might have just connected to a bad node, and core should resolve the issue itself.

Perhaps you have a virus on the computer. Or some piece of hardware is failing. Have you tried swapping out hard drives or booting from a live CD or live USB? If it boots quickly with a live CD or USB then your hard drive is likely failing. Otherwise you might have some motherboard issues.

You can do this by forking any open source altcoin that uses the algorithm you would like to use. Mining that coin can be done by using the "generate" option that is in most of the altcoins that were forked from bitcoin. Alternatively, you can setup any mining software and solo mine the coin.

Coinbase recently announced their second Bitcoin Hackathon competetion. There are up to $70,000 of prizes for applications that use bitcoin and/or blockchain technology. The competetion ends on May 19th, 2015 at 11:59 PST. You can check out the full details here: https://developers.coinbase.com/bithackNote: I am not affiliated with Coinbase. I thought that I should just let everyone know about this new competetion. |

Start bitcoin-qt and it should ask you if you would like to rebuild and rescan the blockchain. Click OK and it will rebuild and fix the issue. After you are done, shut down bitcoin-qt and start armory.

Bitcoind crashed again and I had to rescan and rebuild the database. Why does this happen?

I believe by definition this is a pyramid scheme, and not a ponzi. It may also be a scam, but that cannot be verified unless the source code is looked at. This would only be a scam if microzee received all the money. Since he says many times that he is willing to provide source code, I would like to take a look at that source.

Try re-syncing the tree and recompiling. There may be a bug in the version you pulled from their git repository.
If you are trying to run two bitcoin nodes from the same data directory, you won't be able to as one node will not be able to lock onto the directory.
Otherwise, I've got nothing else.
|
|
|
|
|
Check if both nodes run the same version. I believe that Bitcoin Core 0.10.0 uses a different database and block organization that is not compatible with other versions.
You might also have some permissions issues between the Linux system and Windows.
|
|
|

That error usually means that the databases somehow got corrupted. Try doing: bitcoind -reindex -datadir=/directory/to/blockchain
