System requirements bitcoin
Financial philosophy aside, the hardware part of the bitcoin equation is simple. Despite their well-earned reputation for gobbling up GPUs, the rest of a mining rig’s layout is very lean. You won’t. Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node. Desktop or laptop hardware running recent versions of . Bitcoin Core Bitcoin Core gives you increased security and privacy at a cost. You need to take responsibility for the security of your bitcoins, meet higher minimum system requirements, and beware of some possible problems. No matter what Bitcoin software you use, you should never buy more bitcoins than you can afford to lose.

Bitcoin Core full nodes have certain requirements. A broadband Internet connection with upload speeds of at least kilobits 50 kilobytes per second. Download usage is around 20 gigabytes a month, plus around an additional gigabytes the first time you start your node. You can do other things with your computer while running a full node. More hours would be better, and best of all would be if you can run your node continuously. Note: many operating systems today Windows, Mac, and Linux enter a low-power mode after the screensaver activates, slowing or halting network traffic.
This is often the default setting on laptops and on all Mac OS X laptops and desktops. Legal: Bitcoin use is prohibited or restricted in some areas. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This problem mostly affects computers running Windows. Attack target: Bitcoin Core powers the Bitcoin peer-to-peer network, so people who want to disrupt the network may attack Bitcoin Core users in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth.
Initial block download refers to the process where nodes synchronize themselves to the network by downloading blocks that are new to them. This will happen when a node is far behind the tip of the best block chain. In the process of IBD, a node does not accept incoming transactions nor request mempool transactions.
If you are trying to set up a new node following the instructions below, you will go through the IBD process at the first run, and it may take a considerable amount of time since a new node has to download the entire block chain which is roughly gigabytes now. During the download, there could be a high usage for the network and CPU since the node has to verify the blocks downloaded , and the client will take up an increasing amount of storage space reduce storage provides more details on reducing storage.
Before the node finishes IBD, you will not be able to see a new transaction related to your account until the client has caught up to the block containing that transaction. The following instructions describe installing Bitcoin Core using tools available in most mainstream Linux distributions. We assume you use a Bourne-like shell such as bash. Using any computer, go to the Bitcoin Core download page and verify you have made a secure connection to the server.
If necessary, move the file to the computer you want to use to run Bitcoin Core. The 0. Earlier releases were signed by Wladimir J.
You should verify these keys belong to their owners using the web of trust or other trustworthy means. Then use PGP to verify the signature on the release signatures file. Finally, use PGP or another utility to compute the SHA hash of the archive you downloaded, and ensure the computed hash matches the hash listed in the verified release signatures file.
Make sure you use an account that can use su or sudo to install software into directories owned by the root user. If you logged in graphically, start a terminal. Locate the file you downloaded and extract it using the tar command followed by the argument xzf followed by the file name. The argument xzf means eXtract the gZipped tar archive File.
For example, for a bit tar archive in your current directory, the command is:. This will create the directory bitcoin If you use sudo to run commands as root, use the following command line:. If you use su to run commands as root, use the following command line:. To use the Bitcoin Core daemon bitcoind , which is useful for programmers and advanced users, proceed to the Bitcoin Core Daemon section below.
All of them should be available in all major recently-released Linux distributions, but they may not be installed on your computer yet. If all the required libraries are installed, Bitcoin Core will start. If a required library is missing, an error message similar to the following message will be displayed:. You will be prompted to choose a directory to store the Bitcoin block chain and your wallet. Unless you have a separate partition or drive you want to use, click Ok to use the default.
Bitcoin Core GUI will begin to download the block chain. This step will take at least several days, and it may take much more time on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time by closing it; it will resume from the point where it stopped the next time you start it.
After download is complete, you may use Bitcoin Core as your wallet or you can just let it run to help support the Bitcoin network. Starting your node automatically each time you login to your computer makes it easy for you to contribute to the network.
This only works in desktop environments that support the autostart specification , such as Gnome, KDE, and Unity.
On the Main tab, click Start Bitcoin on system login. Click the Ok button to save the new settings. The next time you login to your desktop, Bitcoin Core GUI should be automatically started as an icon in the tray. You have now completed installing Bitcoin Core. To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
The steps in this section should be performed as the user you want to run Bitcoin Core. This can be a locked account used only by Bitcoin Core. If you changed users in a graphical interface, start a terminal. It will print a message that Bitcoin Core is starting.
To interact with Bitcoin Core daemon, you will use the command bitcoin-cli Bitcoin command line interface. Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli :.
After it starts, you may find the following commands useful for basic interaction with your node: getblockchaininfo , getnetworkinfo , getnettotals , getwalletinfo , stop , and help. A complete list of commands is available in the Bitcoin. When Bitcoin Core daemon first starts, it will begin to download the block chain.
You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it. Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab on most distributions, run the following command:.
Save the file and exit; the updated crontab file will be installed for you. On most distributions, this will cause Bitcoin Core daemon to be automatically started each time your reboot your computer.
Go to the Bitcoin Core download page and verify you have made a secure connection to the server. Click the large blue Download Bitcoin Core button to download the Bitcoin Core installer to your desktop. Windows will ask you to confirm that you want to run it. Click Yes and the Bitcoin installer will start. If you want to use the Bitcoin Core daemon bitcoind , which is useful for programmers and advanced users, proceed to the Bitcoin Core Daemon section below.
When the Bitcoin Core icon appears as shown below , click on it. Your firewall may block Bitcoin Core from making outbound connections. Keep in mind that some BIOS adjustments will be required to maximize stability with more than a couple of cards. While a hand-me-down gaming motherboard should be sufficient for a starter rig, serious enthusiasts use boards made for mining, such as this Asus B Mining Expert that supports a crazy 19 GPUs.
More serious cryptocurrency hobbyists use dedicated mining motherboards that have pre-tweaked BIOS settings and the ability to connect over a dozen GPUs. But supply and demand issues are a recurring theme with mining rigs, and the boards that support more than six GPUs are often out of stock or seriously overpriced. This is how you get half a dozen or more double-slot sized GPUs to fit on one motherboard.
Celerons, single-stick memory configurations, and other money saving shortcuts are all fine here. This is a perfect place to use items off the spare parts shelf. Dust off that dual-core Celeron, puny Pentium, or Ivy Bridge antique. They all work just fine in a mining rig. There's a small corollary here, and it's that CPU mining of certain algorithms is still potentially profitable.
You're probably better off buying another graphics card rather than worrying about CPU mining potential. Right now they're expensive though. But check this listing to make sure. Be wary of second-hand cards formerly used in mining rigs however, as the stress shortens the lifespan of the hardware considerably. One area requiring investment is the power supply. Typical multi-GPU cryptocurrency setups require plenty of juice, more than even a high-end gaming system, and these PSUs will cost you.
A gold rated power supply is minimum, since mining rigs run at constant high loads, and depending on what GPUs you're running and how many of them , you'll want at least a W output, if not more. This Corsair HXi has the capacity for several high-end graphics cards. You'll need all the efficiency you can get.
Something else to keep in mind with power use is your power circuit. Most US homes come with 15A circuit breakers, which means a single circuit will top out at around W. If you're thinking about setting up multiple mining rigs, you'll need to keep them on separate breakers.
A Raspberry Pi runs with an SD. SD is known for its limited rewriting capabilities it's not a heavy duty storage solution, it will bite the dust after a while and on top of that there's also the very important factor of the data transfer rate. Some of the top single board computers could perform well, and I think this is the best solution for a low power-consumption full node. A low-spec computer could deliver great results with some lightweight linux distributions, my personal favorite is Lubuntu that comes with an LX11DE UI and then bitcoin's installation would be as easy as:.
You can run a Raspberry Pi with bitcoind no problem. I have several Pi's running bitcoind in various locations and some of them have over connections.
Use a 64GB flash card and make sure you have a MB swap file. The only limitation you will find is your broadband upload speed , the Pi or it's flashcard will not be the bottlekneck. Use a good quality flash card like Sandisk etc. Also tell your router to route incoming connections on port to your Pi's IP address. The reason the only limitation is your broadband upload speed is because of parasitic loads such as new users trying to upload the entire blockchain from your Pi. If you do this , try to set your Pi up with blockcahin already loaded onto flash or SSD otherwise it will take some time to synchronise.
