I couldn't find any answer so I post this, why takes so long to down load the bloody block chain with Bit coin Core?
I mean wtf? it just runs for hours and all it does is downloading 1k or 2k blocks have no internet problems and I only run the core client
Is there any command or doing anything to download block chain fast?

its like downloading the whole ledger since time so it really would take that long.  that is why I don't use the core but multibit. i'm not sure what is with multibit but it doesn't take that long when updating/syncing. If you don't want to wait, you may wanna use the web wallet instead.

Blockchain is about 60 GB at the moment.
And its not only the downloading.. its indexing too.

I know it's 60GB it says so in the start I'm not an idiot only I sent some coins from my online wallet to my core wallet address.
And I can't spend it at least not till my wallet is 100% synced with network, I wanted to know if there are any way to spend them and since I already downloaded 30GB not going just to drop :)

download a light-wallet (I recommend electrum) and import/sweep the private key of your bitcoin address. then you'll be able to spend bitcoins without having to download the block chain.

It took me over one day + for the entire block-chain to load on my computer. Downloading and waiting for about the 60GB+ of the Blockchain to be downloaded in a reasonable amount of time isn't just feasible. You should try to use a lite-client. My two favorite are Multi-Bit and Electrum.

Downloading it doesn't take too long the issue is the CPU and hard drive usage of verify the blockchain.  This can take days on the first run.  To keep if from being necessary a second time I back up not only my wallet.dat but the entire bitcoin data directory.

why not you trying use torent ?

if you have highest speed and unlimited bandwith im sure you can download it in some minutes ( you must use NASA network )   :D

So if you sent bitcoins to your bitcoin core wallet you could just pull them into Electrum without the need for a full sync?

Thanks

yes. or just don't use bitcoin core in the first place if you don't want to download 60GB+ of data.

That's the client, not the blockchain.
I currently count 74 GB. It's not only the download, it's also "the other side" where the nodes have to give you the data. On a HDD it takes a lot of activity checking the data, on a SSD it will probably be faster. And it also eats CPU-power.
I imagine Bitcoin has been doing several transactions per second for the past 7 years. A HDD will have to re-check all these transactions, with an access time allowing a maximum of a few hundred per second. That makes it something you simply cannot do in a few hours, no matter what your internet speed is.
A SSD will be faster, but mine isn't even big enough for the whole blockchain.

That seems to have worked. Cheers. Is there any reason why it says [unconfirmed]? Please feel free to point me in the direction of newbie bitcoin tutorial apologies :)

if you used the sweep feature on electrum, it means the transaction between the address which private keys you sweeped and your newly generated address are still unconfirmed.
sweeping transfers bitcoins to a new address. importing lets you use the old address (although it's not possible to import private key on standard electrum wallet.)

btw create a new thread if you have further questions. we're getting a bit off-topic here.

You can import private key to online wallet https://multicoins.org
Instructions how to get private key from Bitcoin Core:

click on 'help' in the menu bar (top right)
click on 'debug window'
select the 'console' tab
type: walletpassphrase "your walletpassphrase here" 600
type: dumpprivkey [your public key here]
this will return the private key, you can copy it now; ensure you clear your clipboard/history afterwards
type: walletlock

it's the same, using torrent will also require you a good amount of time to download 60 giga, unless he has a very fast connection

otherwise he only need a good cpu and a good ssd, which are very cheap nowadays

It's not really just the size its because it has to sync years and years of transactions so its a lot of work. Why not just use a webwallet for now ? I used one and it works just fine. You will be able to send or recieve btc right away.


Unconfirmed is no reason for alarm. Its simply in the process of queueing your transaction with the miners on the blockchain. After the first confirm your amount will reflect, sometimes even before but you cannot spend until it confirms.
