Fallback Nodes

2015-03-17T04:41:25Z

Grue: add new tor node

This is a list of nodes which are considered reliable.

== How to use this list ==

=== Connect to nodes ===

You can connect to these nodes with the ''-addnode=ip'' switch instead of the usual node harvesting process (through IRC or via the embedded nodelist). You can connect to more than one node by using ''-addnode=ip'' more than once. It is usually a good idea to connect to more than one of these nodes.

==== Nodes without a fixed ip ====

If the node IP is not fixed (see "Fixed" column), you will have to resolve the node's name (first column) each time the IP changes. Some nodes may have their ip change once a day, some others once a month, and some others may stay on the same IP for years. Still, as long as the IP is not fixed, there is no guarantee it will stay the same.

In order to enable hostname lookups for the ''-addnode'' and ''-connect'' parameters, you must additionally provide the ''-dns'' parameter. Example:
bitcoind -dns -addnode=bitcoin.es

Versions prior to 0.3.22 do not support hostnames to the ''-addnode'' parameter, so you must do the resolving part for it. For example on linux:
bitcoind -addnode=$(dig +short bitcoin.es)

=== IP Transactions ===

[[Bitcoin Core]] versions prior to 0.8.0 also could send [[IP Transactions]] to these nodes. If you included your bitcoin address in the "message" field, you might have had your coins back.

=== Tor network ===

To use Bitcoin-Qt over Tor hidden services, in a terminal/console enter:
bitcoin-qt -proxy=127.0.0.1:9050 -onlynet=tor

To use Bitcoin with one specific Tor node, run
bitcoin-qt -proxy=127.0.0.1:9050 -connect=abcde.onion
, where abcde.onion needs to be substituted with one of the [[Fallback_Nodes#Tor_nodes|Tor nodes below]]. These parameters can be added to [[Running_Bitcoin#Bitcoin.conf_Configuration_File|bitcoin.conf]] to make them permanent.

You can find detailed information on running clients and hidden services within Tor in the [https://github.com/bitcoin/bitcoin/blob/master/doc/tor.md documentation].

== Adding a node ==

Before adding yourself as a fallback node, you should be sure your node will stay online for a long time. If a node is offline for more than 24 hours it will be removed from the list.

To add a node in this list, you just need the ip/hostname and your name, the other fields will be filled automatically. Insert the following lines before the <tt>END NODELIST</tt> line:

<nowiki>|-
| ip || your name</nowiki>

Fallback Nodes

2015-03-17T04:34:15Z

Grue: switched places for IPv6 and IPv4. IPv4 is more prevalent than IPv6. Showing that first prevents confusion for novice users.

This is a list of nodes which are considered reliable.

== How to use this list ==

=== Connect to nodes ===

You can connect to these nodes with the ''-addnode=ip'' switch instead of the usual node harvesting process (through IRC or via the embedded nodelist). You can connect to more than one node by using ''-addnode=ip'' more than once. It is usually a good idea to connect to more than one of these nodes.

==== Nodes without a fixed ip ====

If the node IP is not fixed (see "Fixed" column), you will have to resolve the node's name (first column) each time the IP changes. Some nodes may have their ip change once a day, some others once a month, and some others may stay on the same IP for years. Still, as long as the IP is not fixed, there is no guarantee it will stay the same.

In order to enable hostname lookups for the ''-addnode'' and ''-connect'' parameters, you must additionally provide the ''-dns'' parameter. Example:
bitcoind -dns -addnode=bitcoin.es

Versions prior to 0.3.22 do not support hostnames to the ''-addnode'' parameter, so you must do the resolving part for it. For example on linux:
bitcoind -addnode=$(dig +short bitcoin.es)

=== IP Transactions ===

[[Bitcoin Core]] versions prior to 0.8.0 also could send [[IP Transactions]] to these nodes. If you included your bitcoin address in the "message" field, you might have had your coins back.

=== Tor network ===

To use Bitcoin-Qt over Tor hidden services, in a terminal/console enter:
bitcoin-qt -proxy=127.0.0.1:9050 -onlynet=tor

To use Bitcoin with one specific Tor node, run
bitcoin-qt -proxy=127.0.0.1:9050 -connect=abcde.onion
, where abcde.onion needs to be substituted with one of the [[Fallback_Nodes#Tor_nodes|Tor nodes below]]. These parameters can be added to [[Running_Bitcoin#Bitcoin.conf_Configuration_File|bitcoin.conf]] to make them permanent.

You can find detailed information on running clients and hidden services within Tor in the [https://github.com/bitcoin/bitcoin/blob/master/doc/tor.md documentation].

Grue: updated blockchain size

[[Image:MultiBit_0.4.23_screenshot_WinXP.png|right|800px|screenshot of Multibit with its Windows XP GUI and Metal theme]]
[http://multibit.org MultiBit] is a lightweight "[[Thin Client Security|thin client]]" Bitcoin wallet for Windows, MacOS and Linux based on [[BitCoinJ|bitcoinj]]. Its main advantages over the [[Bitcoin-Qt#Criticism|original Bitcoin client]] include support for opening multiple wallets simultaneously, and not requiring the download of the entire multi-gigabyte [[block chain]] (22.5GB as of October 2014<ref>[https://blockchain.info/charts/blocks-size Bitcoin Blockchain Size]</ref>). The project is lead by UK developer Jim Burton.<ref>[http://www.youtube.com/watch?v=MnkssdmlaWw European Bitcoin Conference 2012 - Jim Burton - Multibit]</ref>

==Features==
* Multiple wallets can be open at the same time
* Synchronizes with the network in minutes
* Shows the last BTC <--> USD rate from [[VirtEx]] and other exchanges
* Import and export your private keys
* Chart of your balance over the last 30 days
* Free and open source (MIT license)
* Localized in a variety of languages

Mining rig

2011-06-07T16:09:24Z

Grue: Only need 1 GB of ram, especially with linux coin

A '''mining rig''' is a computer system used for [[How_bitcoin_works#Bitcoin_mining|mining bitcoins]]. The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.

==Tips==

* Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed. Choose a motherboard with no on-board graphics.
* The following component lists might be used to help in building a new rig. To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.

Note: this build requires a "dremel" modification to the pcie adapter for the x16 card to fit into it. Using this adapter also means that one of the cards will not be mounted in a typical case location.
