Running A Total Knot

Support the Bitcoin network by running your own utter knot

What Is A Total Knot?

A utter knot is a program that fully validates transactions and blocks. Almost all total knots also help the network by accepting transactions and blocks from other total knots, validating those transactions and blocks, and then relaying them to further total knots.

Most total knots also serve lightweight clients by permitting them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough knots perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.

Many people and organizations volunteer to run total knots using spare computing and bandwidth resources—but more volunteers are needed to permit Bitcoin to proceed to grow. This document describes how you can help and what helping will cost you.

Costs And Warnings

Running a Bitcoin utter knot comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can determine whether you’re able to help the network.

Special Cases

Miners, businesses, and privacy-conscious users rely on particular behavior from the utter knots they use, so they will often run their own total knots and take special safety precautions. This document does not voorkant those precautions—it only describes running a total knot to help support the Bitcoin network te general.

Please seek out assistance ter the community if you need help setting up your utter knot correctly to treat high-value and privacy-sensitive tasks. Do your own diligence to ensure who you get help from is ethical, reputable and qualified to assist you.

Secure Your Wallet

It’s possible and safe to run a total knot to support the network and use its wallet to store your bitcoins, but you vereiste take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet pagina for more information.

Ondergrens Requirements

Bitcoin Core utter knots have certain requirements. If you attempt running a knot on powerless 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 knot.

Desktop or laptop hardware running latest versions of Windows, Mac OS X, or Linux.

145 gigabytes of free disk space

Two gigabytes of memory (RAM)

A broadband Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) vanaf 2nd

An unmetered connection, a connection with high upload boundaries, or a connection you regularly monitor to ensure it doesn’t exceed its upload boundaries. It’s common for total knots on high-speed connections to use 200 gigabytes upload or more a month. Download usage is around 20 gigabytes a month, plus around an extra 140 gigabytes the very first time you begin your knot.

6 hours a day that your utter knot can be left running. (You can do other things with your pc while running a utter knot.) More hours would be better, and best of all would be if you can run your knot continuously.

Note: many operating systems today (Windows, Mac, and Linux) inject 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. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your rekentuig is running.

Possible Problems

Bandwidth boundaries: Some Internet plans will charge an extra amount for any excess upload bandwidth used that isn’t included te the project. Worse, some providers may terminate your connection without warning because of overuse. Wij advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can zekering Bitcoin Core before you reach your upload limit.

Anti-virus: Several people have placed parts of known rekentuig viruses ter the Bitcoin block chain. This block chain gegevens can’t infect your laptop, but some anti-virus programs quarantine the gegevens anyway, making it more difficult to run Bitcoin Core. 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 te ways that will affect other things you do with your rekentuig, such spil an attack that thresholds your available download bandwidth.

The next time you login to your desktop, Bitcoin Core daemon will be automatically commenced.

You have now ended installing Bitcoin Core. If you have any questions, please ask te one of Bitcoin’s many communities, such spil Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.

To support the Bitcoin network, you also need to permit incoming connections. Please read the Network Configuration section for details.

Upgrading Bitcoin Core

If you are running an older version, shut it down. Wait until it has totally shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy overheen /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

The blockchain and wallet files te the gegevens directory are compatible inbetween versions so there is no requirement to make any switches to the gegevens directory when upgrading. Sometimes the format of those files switches, but the fresh Bitcoin Core version will include code that automatically upgrades the files to the fresh format so no manual intervention is required.

Sometimes upgrade of the blockchain gegevens files from very old versions to the fresh versions is not supported. Te those cases it may be necessary to redownload the blockchain. Check the release notes of the fresh version if you are programma to upgrade from a very old version.

Sometimes downgrade is not possible because of switches to the gegevens files. Again, check the release notes for the fresh version if you are programma to downgrade.

Network Configuration

If you want to support the Bitcoin network, you voorwaarde permit inbound connections.

When Bitcoin Core starts, it establishes 8 outbound connections to other total knots so it can download the latest blocks and transactions. If you just want to use your total knot spil a wallet, you don’t need more than thesis 8 connections—but if you want to support lightweight clients and other total knots on the network, you vereiste permit inbound connections.

Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based knot accepts inbound connections.

Huis connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to permit inbound connections to Bitcoin’s port, port 8333. Unluckily many routers don’t permit automatic configuration, so you vereiste by hand configure your router. You may also need to configure your firewall to permit inbound connections to port 8333. Please see the following subsections for details.

Testing Connections

The BitNodes project provides an online instrument to let you test whether your knot accepts inbound connections. To use it, embark Bitcoin Core (either the GUI or the daemon), wait Ten minutes, and then visit the Bitnodes pagina. The contraption will attempt to guess your IP address—if the address is wrong (or wit), you will need to inject your address by hand.

After you press Check Knot, the device will inform you whether your port is open (green opbergruimte) or not open (crimson opbergruimte). If you get the green opbergruimte, you don’t need to do anything—you accept inbound connections. If you get the crimson opbergruimte, please read the enabling connections subsection.

For confirmation that you accept inbound connections, you can use Bitcoin Core. Bitcoin Core can’t tell you directly whether you permit inbound connections, but it can tell you whether or not you presently have any inbound connections. If your knot has bot online for at least 30 minutes, it should normally have inbound connections. If want to check your peer informatie using Bitcoin Core, choose the adequate instructions below:

GUI Peer Informatie

Ter the bottom right corner of the Bitcoin Core GUI are several icons. If you hover overheen the signal strength icon, it will tell you how many connections you have. The icon won’t turn green until you have more than 8 active connections, which only happens if inbound connections are permitted.

For confirmation, you can go to the Help spijskaart, choose Debug Window, and open the Information tabulator. Te the Network section, it will tell you exactly how many inbound connections you have. If the number is greater than zero, then inbound connections are permitted.

If you don’t have inbound connections, please read the instructions for enabling inbound connections.

Daemon Peer Informatie

The getconnectioncount guideline will tell you how many connections you have. If you have more than 8 connections, inbound connections are permitted. For example:

For confirmation, you can use the getpeerinfo instruction to get information about all of your peers. Each peer’s details will include an inbound field set to true if the connection is inbound. If you have any inbound connections, then inbound connections are permitted.

If you don’t have inbound connections, please read instructions for enabling inbound connections.

Enabling Connections

If Bitcoin Core can’t automatically configure your router to open port 8333, you will need to by hand configure your router. We’ve attempted to make the following instructions generic enough to voorkant most router models, if you need specific help with your router, please ask for help on a tech support webpagina such spil SuperUser.

Enabling inbound connections requires two steps, plus an reserve third step for firewall users:

Providing your laptop a static (unchanging) internal IP address by configuring the Dynamic Host Configuration Protocol (DHCP) on your router.

Forwarding inbound connections from the Internet through your router to your rekentuig where Bitcoin Core can process them.

Configuring your firewall to permit inbound connections. This step mainly applies to Windows users, spil Mac OS X and most Linuxes do not enable a firewall by default.

Configuring DHCP

Te order for your router to onmiddellijk incoming port 8333 connections to your pc, it needs to know your computer’s internal IP address. However, routers usually give computers dynamic IP addresses that switch frequently, so wij need to ensure your router always gives your laptop the same internal IP address.

Begin by logging into your router’s administration interface. Most routers can be configured using one of the following URLs, so keep clicking linksaf until you find one that works. If none work, consultatie your router’s manual.

Upon connecting, you will very likely be prompted for a username and password. If you configured a password, inject it now. If not, the Router Passwords webpagina provides a database of known default username and password pairs.

After logging te, you want to search your router’s menus for options related to DHCP, the Dynamic Host Configuration Protocol. Thesis options may also be called Address Reservation. For example, the router pagina shown below calls the option wij need “DHCP Reservation”:

Ter the reservation configuration, some routers will display a list of computers and devices presently connected to your network, and then let you select a device to make its current IP address voortdurend:

If that’s the case, find the laptop running Bitcoin Core te the list, select it, and add it to the list of reserved addresses. Make a note of its current IP address—we’ll use the address te the next section.

Other routers require a more manual configuration. For thesis routers, you will need to look up the immobile address (MAC address) for your computer’s network card and add it to the list. This operation differs by operating system:

Windows 7 &, 8: Press Win-R (Windows key plus the R key) to open the Run dialog. Type cmd to open the console. Type ipconfig /all and find the result that best matches your connection—usually a wireless connection. Look for a line that starts with “Physical Address” and contains a value like this:

Substitute all the dashes with colons, so the address looks like this: 01:23:45:67:89:AB. Use that address te the instructions below.

Linux: open a terminal and type ifconfig . Find the result that best matches your connection—a result embarking with wlan indicates a wireless connection. Find the field that starts with HWaddr and copy the instantly following field that looks like 01:23:45:67:89:ab. Use that value te the instructions below.

Mac OS X: open a terminal and type ifconfig . Find the result that best matches your connection—a result embarking with en1 usually indicates a wireless connection. Find the field that starts with ether: and copy the instantly following field that looks like 01:23:45:67:89:ab. Use that value ter the instructions below.

Once you have the MAC address, you can pack it into to your router’s manual DHCP assignment table, spil illustrated below. Also choose an IP address and make a note of it for the instructions te the next subsection. After coming in this information, click the Add or Save button.

Then reboot your laptop to ensure it gets assigned the address you selected and proceed to the Port Forwarding instructions below.

Port Forwarding

For this step, you need to know the local IP address of the laptop running Bitcoin Core. You should have this information from configuring the DHCP assignment table ter the subsection above.

Login to your router using the same steps described near the top of the DHCP subsection. Look for an option called Port Forwarding, Port Assignment, or anything with “Port” ter its name. On the some routers, this option is buried ter an Applications &, Gaming menukaart.

The port forwarding settings should permit you to ordner an outward port on your router to the “internal port” of a device on your network spil shown ter the screenshot below.

Both the outward port and the internal port should be 8333 for Bitcoin. (You may also want to schrijfmap port 18333 for Bitcoin’s testnet, albeit this guide does not voorkant using testnet.) Make sure the IP address you inject is the same one you configured ter the previous subsection.

After packing te the details for the mapping, save the entry. You should not need to restart anything. Begin Bitcoin Core (if you haven’t already) and go after the Testing Connections instructions to test your connection.

If you still can’t connect and you use a firewall, you very likely need to switch your firewall settings. See the Firewall section below.

If something else went wrong, it’s very likely a problem with your router configuration. Re-read the instructions above to see if you missed anything, search the web for help with “port forwarding”, and ask for help on sites like SuperUser.

Wij can’t provide rechtstreeks support, but if you see a way to improve thesis instructions, please open an punt.

Firewall Configuration

Firewalls block inbound connections. To use Bitcoin, you need to configure your computer’s firewall to permit connections to port 8333. This is usually spil effortless spil beginning your firewall configuration software and defining a fresh rule to permit inbound connections to port 8333. For extra information for Windows, see the linksom below:

Mac OS X comes with its firewall disabled by default, but if you have enabled it, see the section Permitting Specific Applications from the official Apple guide.

Ubuntu also comes with its firewall disabled by default, but if you have enabled it, see the Ubuntu wiki pagina for information about adding port forwarding rules.

Once you have permitted inbound connections to port 8333, commence Bitcoin Core (if you haven’t already) and go after the Testing Connections instructions to test your connection.

If something else went wrong re-read the DHCP, port forwarding, and firewall instructions above to see if you missed anything, search the web for help with “port forwarding” and “opening firewall ports”, and ask for help on sites like SuperUser.

Wij can’t provide rechtstreeks support, but if you see a way to improve thesis instructions, please open an punt.

Configuration Tuning

This section contains advice about how to switch your Bitcoin Core configuration to adapt it to your needs.

There are two ways to switch your configuration. The very first is to begin Bitcoin Core with the options you want. For example, if you want to limit it to using one CPU core for signature verification, you can commence Bitcoin Core like this:

Once you’ve determined you like an option, you can add it to the Bitcoin Core configuration verkeersopstopping. You can find that verkeersopstopping te the following directories:

OSX: $Huis/Library/Application Support/Bitcoin/

To add an option to the configuration verkeersopstopping, just liquidate its leading dash. You may also need to eliminate any quotation marks you used te your shell. For example, the -par option seen above would look like this ter the configuration verkeersopstopping:

A user-friendly configuration verkeersopstopping generator is available here. If you have any questions about configuring Bitcoin Core, please zekering by one of our forums or live chatrooms.

Reduce Storage

It is possible to configure your knot to to run te pruned mode te order to reduce storage requirements. This can reduce the disk usage from overheen 145GB to around 5GB.

Running a knot ter pruned mode is incompatible with -txindex and -rescan . It also disables the RPC importwallet . Two RPCs that are available and potentially helpful, however, are importprunedfunds and removeprunedfunds .

To enable block pruning set prune=N on the instruction line or ter bitcoin.conf , where N is the number of MiB to allot for raw block and undo gegevens.

A value of 0 disables pruning. The minimal value above 0 is 550 . Your wallet is spil secure with high values spil it is with low ones. Higher values merely ensure that your knot will not shut down upon blockchain reorganizations of more than Two days – which are unlikely to toebijten ter practice. Ter future releases, a higher value may also help the network spil a entire because stored blocks could be served to other knots.

Reduce Traffic

Some knot operators need to overeenkomst with bandwidth caps imposed by their ISPs.

By default, bitcoin-core permits up to 125 connections to different peers, 8 of which are outbound. You can therefore, have at most 117 inbound connections.

The default settings can result te relatively significant traffic consumption.

Ways to reduce traffic:

Maximum Upload Targets

A major component of the traffic is caused by serving historic blocks to other knots during the initial blocks download phase (syncing up a fresh knot). This option can be specified te MiB vanaf day and is turned off by default. This is not a hard limit, only a threshold to minimize the outbound traffic. When the limit is about to be reached, the uploaded gegevens is cut by no longer serving historic blocks (blocks older than one week). Keep ter mind that fresh knots require other knots that are willing to serve historic blocks. The recommended ondergrens is 144 blocks vanaf day (max. 144MB vanaf day)

Disable listening

Disabling listening will result ter fewer knots connected (recall the maximum of 8 outbound peers). Fewer knots will result ter less traffic usage spil you are relaying blocks and transactions to fewer knots.

Reduce maximum connections

Reducing the maximum connected knots to a ondergrens could be desirable if traffic thresholds are lil’. Keep ter mind that bitcoin’s trustless proefje works best if you are connected to a handful of knots.

Blocks-only mode

Causes your knot to zekering requesting and relaying transactions unless they are part of a block and also disables listening spil described above.

This reduces your node’s bandwidth to the absolute ondergrens necessary to stay synchronized with the network, about 150 megabytes incoming gegevens vanaf day and about 1 megabyte of outgoing gegevens vanaf day, but it does mean that your knot won’t see incoming transactions until they’ve received at least one confirmation.

You will still be able to send transactions from the built-in wallet or from peers you’ve whitelisted using the -whitelist parameter.

The pending block pay-outs have bot executed spil expected.

Thank you for your continuous support.

Te the beginning Bitcoin network transactions where secured by individual hobbyist miners. With the introduction of ASIC hardware security, functionality has bot disproportionately concentrated into a handful of corporations making it less secure.

Bitcoin Gold blockchain database is going to be secured with Equihash algorithm that is ASIC resistant. Being able to mine bitcoin with conventional GPU hardware ensures Bitcoin Gold network security functions are well distributed across the world.
