Bitcoin is a digital currency created in 2009 by Satoshi Nakamoto. The name also refers both to the open source software he designed to make use of the currency and to the peer-to-peer network formed by running that software. Unlike other digital currencies, Bitcoin avoids central authorities and issuers. Bitcoin uses a distributed database spread across ...

I've actually already talked about this on StackExchange but here we go again :) There's a barrier when you try to purchase Bitcoins, Litecoins or any other crypto currency for that matter with a form of payment that allows chargeback (i.e. Paypal or a credit card). Take a look at Paypal's TOS section 3.7. You can still use VirWox to buy Second Life Lindens ...

Your wallet.dat file records all of the important information. I don't know if the other files also contain confidential information, but two things are sure: Your private keys are only stored in wallet.dat. If you keep that file safe, and all of the other files get leaked out, nobody can steal your money (though they may find out other things about you). ...

When you first start, it has to download data from the Bitcoin network so that it can have something to work with. Just give it some time and it'll eventually start generating.

Looks like you do just have to backup/transfer the wallet.dat From their faq: How do I backup my wallet? Your wallet.dat is stored in the directory ''%appdata%\Bitcoin'', which is typically: Windows XP: C:\Documents and Settings\username\Application Data\Bitcoin Windows Vista: C:\Users\username\AppData\Roaming\Bitcoin ...

In nearly every case, it comes down to what the GPU is good at. Architecturally modern GPUs consist of a massive number of small cores. They are as such good at embarassingly parallel problems and happen to be good at vector calculations (as opposed to floating point, where CPUs often do better). Rather than using a GPU as well, a GPU, all these tasks use it ...

Nehalem and Sandy Bridge CPUs The GPUs inside Core iX-YYY and Core iX-2YYY aren't OpenCL capable, so mining operations are actually performed by the CPU, not the integrated GPU. Ivy Bridge CPUs The GPUs inside Core iX-3YYY are OpenCL capable, but even the fastest of them (Core i7-3xx7U) have 16 execution units and a core clock of up to 1300 MHz. In ...

Are you referring to the litecoin-qt client with GUI? Button "Receive coins" -> Button "+ New Address" Alternatively you can also create addresses on liteaddress.org. But be sure to save it to your hard disk first and execute it offline. Otherwise your private key (ie your right to spend the money) will travel through the net and possibly be stolen.

Someone might steal your hard drive, so run your PC from a live-CD, and remove all persistent storage except for your Thumb Drive that contains the sensitive data. Physically secure the Thumb Drive. They can still use advanced techniques to read your RAM after the PC is powered off, so rig your PC to be destroyed with thermite in case of emergency.

Minerd.exe*32 is a process to mine bitcoins. Basically, the bitcoin network throws a very complex problem at all computers running this, and the first computer (or pool of computers) gets a reward. Obviously solving a very difficult math problem takes a lot of processing power. I recommend running malwarebytes and checking for viruses. Formatting your ...

Get the latest release! Again only put in your wallet.dat, let it download the blockchain. This can really take some time (up to several hours) until your blockchain has caught up with the current status - then everything should be fine. If there are still transactions missing run a -rescan after the blockchain was downloaded completely

Both NVidia and AMD have a separate programming languages (CUDA and OpenCL) to allow access to their GPUs for non-3D game programming. The bitcoin mining programs are using these interfaces to take advantage of the highly parallel nature of the GPUs to accelerate the computations. At this time Intel GPUs only accelerate 3D games through DirectX (there is ...

Bitcoin synchronization is a process that relies heavily on disk IOs. In the upcoming Bitcoin-QT version 0.8, the file system will be changed to use LevelDB that is less hard-drive intensive. It may be the case that this will solve your problem. At any rate, the synchronisation is a long process, so it is best to do the initial process while not working on ...

If you are using the motherboard onboard graphics you have "Intel HD Graphics" You need the Intel OpenCL SDK found here: http://software.intel.com/en-us/articles/vcsource-tools-opencl-sdk/ Look for a download button near the top right of the page.

You either need to connect a monitor to the card or connect a dummy plug. Otherwise, the card plays dead. If your monitor has two connections, you can just connect one of them to the card and not use that input.

So I am really close to solving this issue. The basic Idead i had was a multi seat session. This allows the ATI card to have its own X session and the Intel display to have its own X session. Make sure PCIE is the default display for the system but that your onboard GPU is enabled in your system BIOS Modify our /etc/X11/xorg.conf to look like this... ...

"Bitcoin is a peer-to-peer currency. Peer-to-peer means that no central authority issues new money or tracks transactions. These tasks are managed collectively by the network." See more at http://www.bitcoin.org.

Bitcoin is a non-national, internet currency that can be used to make purchases across the web. Like other currencies, it has exchange rates to various national currencies. More on wikipedia

I had this problem on Mac OS 10.5.8. I didn't realize I had to download the "block chain" before starting - which is probably how I got the error in the first place. After getting the error, I needed to go to (User)/Library Rename/delete the Bitcoin folder. Once renamed/deleted, I could launch and run Bitcoin, no problem.

In my experience, Linux is far better supported by the Bitcoin community than Windows is. The same goes for ATI vs. Nvidia; ATI cards are far better at doing the calculations required for mining bitcoins, so all the serious miners use them. 32 vs. 64 bit should also be a non-issue; just pick the 64-bit version of the AMD Stream SDK instead of the 32-bit ...

I'm not sure of how or if this would work - I only have a shallow knowledge of bitcoin, but I would "split up" your wallet. Create a second bitcoin client, and transfer most of your money to it, except for the amount you expect to spend in the near future. You can then keep your main stash offline and away from any computer or network. When saving your ...

I'd first block the connection to the external addresses using the iptables iptables -A OUTPUT -d IP_Address -j DROP Once you've made sure all the IP Addresses are being blocked, save the iptables: # /sbin/service iptables save then clean up the files placed by the hijacker. You may want to look at /etc/var/log/messages and /etc/var/log/secure to see if ...
