Bitcoin symbol

Arthur: Remove broken link

[[File:Btc-sans.png|thumb|128px|The prevailing Bitcoin symbol]]By far the most commonly used symbol for Bitcoin is [[:{{ns:File}}:Btc-sans.png|{{BTC}}]], a capital letter '''B''' with two falling strokes at the top and bottom. This symbol was designed by [[Satoshi Nakamoto]] for the icon of an early version of the [[reference client|original Bitcoin client]], though the very first versions of the Bitcoin client used "BC" instead of any special symbol. Presumably the symbol was intended to look similar to other currency symbols. The symbol represents the currency [[Units|unit]] "bitcoin" (100 million [[Satoshi (unit)|satoshi]]), as well as the Bitcoin network and currency itself. The bitcoin currency unit is also commonly given the informal currency code '''BTC'''.

The Bitcoin sign is part of Unicode 10.0 (released June 2017)<ref name="uc">http://www.unicode.org/versions/Unicode10.0.0/</ref> with code point U+20BF (₿). As of June 2017, font support for the Bitcoin sign is in macOS Sierra, iOS, Android O [https://developer.android.com/preview/download.html beta], Windows 10 [https://support.microsoft.com/en-us/instantanswers/d4efb316-79f0-1aa1-9ef3-dcada78f3fa0/get-the-windows-10-creators-update Creators Update] and several Linux releases. After being rejected in 2011,<ref>http://www.unicode.org/L2/L2011/11129-bitcoin.pdf</ref> the Bitcoin sign was accepted for Unicode in November 2015<ref>https://twitter.com/ken_lunde/status/661351862155669506</ref> and first appeared in Unicode 10.0 in 2017.<ref name="uc"/>

Historically, similar looking Unicode symbols such as the Thai Baht (฿) have been used because the Unicode standard at the time had not included a symbol for Bitcoin. The capital letter B with stroke (Ƀ) was also used in contexts where it was likely that using the Baht symbol would cause confusion.

== Currency code ==
The [https://secure.wikimedia.org/wikipedia/en/wiki/ISO_4217 ISO 4217 currency code] for Bitcoin is '''XBT'''. However, at the moment it is an [https://secure.wikimedia.org/wikipedia/en/wiki/ISO_4217#Without_currency_code unofficial code] according to the ISO 4217 standard. The unit name '''BTC''' is also commonly used to represent one bitcoin, but it violates ISO 4217 because it begins with "BT", the country code of Bhutan. Bhutan does not actually use the code BTC for any currency, and XBT has not yet defined which unit it represents (just that it represents ''some'' unit of bitcoin), so the Bitcoin community is likely to continue using mainly BTC as a unit name and currency code for some time.

A [http://www.coindesk.com/bitcoin-foundation-standardise-bitcoin-symbol-code-next-year/ formal application] by the Financial Standards Working Group of the [[Bitcoin Foundation]] is nearing completion.[still true?] This application would request ISO 4217 standard to support XBT.

== Inserting the symbol ==
In lieu of the Bitcoin symbol being included in the Unicode standard and its adoption into typographic fonts, {{BTC}} can be included in many documents by other means. This section focuses on online publications but the basic concepts apply to all publishing forms.

==== Image ====
The Bitcoin symbol can be inserted as an image, as is done in the opening sentence of this page. The benefit of this method is that any client that can display images in line with text will be able to display the symbol. The down side to this method is that as an image, it does not always degrade as nicely as a font. If using raster image, scaling the image up/down (to fit with surrounding text) may result in pixelation, inappropriate filtering, and other issues typical of raster images. If using a vector image, scaling concerns do not apply but the display would still not benefit from font-specific rendering features such as [[wikipedia:hinting|hinting]]. Both forms also suffer from client-specific considerations such as whether or not a box will be drawn around the image and the general inability to easily style its display; applying color requires specific CSS, and italicizing would require a CSS skew transform, for example.

When using an image in running text on a webpage it's generally a good idea to set the ''alt'' property to an appropriate value. For example, when depicting amounts you might use ''alt="BTC"''. Text including the symbol copied and pasted will then remain syntactically correct, replacing the symbol with BTC.

Sample HTML code:
<nowiki>
.btc { height:1em; position:relative; top:0.17em; cursor:text; }
...
Please send <img src="btc-sans.png" alt="BTC" class="btc" />0.01 to ...
Please send <img src="btc-sans.svg" alt="BTC" class="btc" />0.01 to ...</nowiki>

==== Font Awesome icon ====
The Font Awesome collection of icons and symbols also includes the Bitcoin symbol.<ref>http://fortawesome.github.io/Font-Awesome/icon/btc/</ref>

Sample HTML code:
<nowiki> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css">
...
Please send 0.01 to ...</nowiki>

==== Font ====
As few fonts include the Bitcoin symbol, a special font was created by [[User:Theymos|Theymos]], originally for the [[BitcoinTalk]] forum.<ref>https://bitcointalk.org/index.php?topic=88647</ref> The font consists of only the Bitcoin symbol ({{BTC}}) used in the glyph for the capital letter B. The text "BTC" can be entered and styled with this font, causing it to be replaced entirely with just the symbol on those systems that support this font, while on other systems the text "BTC" is retained. Similarly, copying and pasting text will still retain "BTC". This method is used on BitcoinTalk and the Bitcoin Wiki.

Sample HTML code:
<nowiki> @font-face { font-family: BTC; src: url(BTC.ttf); }
...
Please send BTC0.01 to ...</nowiki>

Fallback Nodes

2015-06-06T15:02:45Z

Arthur: Update info about my node (n.bitcoin-fr.io)

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>

== 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>

Testnet

2015-05-27T16:10:21Z

Arthur: Add flyingkiwi's TestNet Faucet (request from #bitcoin-wiki)

The '''testnet''' is an alternative Bitcoin [[block chain]], to be used for testing. Testnet coins are separate and distinct from actual bitcoins, and are never supposed to have any value. This allows application developers or bitcoin testers to experiment, without having to use real bitcoins or worrying about breaking the main bitcoin chain.

Run bitcoin or bitcoind with the -testnet flag to use the testnet (or put testnet=1 in the bitcoin.conf file).

There have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. '''Testnet3''' is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility.

==Differences==
* Default Bitcoin network protocol listen port is 18333 (instead of 8333)
* Default RPC connection port is 18332 (instead of 8332)
* Bootstrapping uses different DNS seeds.
* A different value of ADDRESSVERSION field ensures no testnet Bitcoin addresses will work on the production network. (0x6F rather than 0x00)
* The protocol message header bytes are 0x0B110907 (instead of 0xF9BEB4D9)
* Minimum [[difficulty]] of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty. In addition, if no block has been found in 20 minutes, the difficulty automatically resets back to the minimum for a single block, after which it returns to its previous value.
* A new genesis block
* The IsStandard() check is disabled so that non-standard transactions can be experimented with.

==Genesis Block==

Testnet uses a different genesis block to the main network. You can find it [https://www.biteasy.com/testnet/blocks/000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943 here] or [http://blockexplorer.com/testnet/b/0 here].
The testnet was [https://github.com/gavinandresen/bitcoin-git/commit/feeb761ba07af74a7cd78b8c8f7c2a961fd9ea1c reset with a new genesis block] for the 0.7 bitcoin release.

==Mining==
[[solo.ckpool]] has a testnet bitcoin solo mining implementation available, without the need to set up bicoind locally.

===Wallets===

Online testnet wallets to help you test your application.

===Faucets===

Once you're done with your test coins, it is a nice gesture to send them back to the faucets, so they become available to other developers.
