Bitcoin symbol

2011-07-21T11:22:02Z

Wareen: /* Submissions */ update reference to original design idea

== Currency code ==
The [https://secure.wikimedia.org/wikipedia/en/wiki/ISO_4217 currency code] for Bitcoin is '''BTC'''. 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 but the official code according to the Bitcoin community.

A [https://forum.bitcoin.org/index.php?topic=7205.msg112577 request] has been made at the [http://www.six-group.com/ organization] maintaining the currency codes in the ISO 4217 standard to support BTC. This has been declined mainly on bases that organizations such as [https://secure.wikimedia.org/wikipedia/en/wiki/Reuters Reuters] and [https://secure.wikimedia.org/wikipedia/en/wiki/Bloomberg Bloomberg] are not reporting on the Bitcoin currency. when this changes a request can be resubmitted.

== Currency sign ==

There is no official currency sign for Bitcoin as of December 2010. As an alternative, the BTC currency code can be used. Some existing Unicode symbols have been proposed but also serious work is being done on creating a custom Bitcoin sign with its own official [https://secure.wikimedia.org/wikipedia/en/wiki/Unicode Unicode] that is recognized by the [https://secure.wikimedia.org/wikipedia/en/wiki/Unicode_Consortium Unicode Consortium]. Note that a currency sign is more complex than creating a logo as will be explained below.

[[File:Example-unicode-reference-currency-signs.png|256px|thumb|right|Examples of Unicode currency sign reference glyphs]]

=== New Unicode symbol ===

In some discussions [https://forum.bitcoin.org/index.php?topic=41.0 41], [https://forum.bitcoin.org/index.php?topic=369.0 369] and [https://forum.bitcoin.org/index.php?topic=7215.0 7215] on the bitcoin forum several designs of an official Bitcoin sign have been proposed. This section on the Wiki is intended to streamline the process of arriving at an official Bitcoin currency sign with its own Unicode character code.

==== Goal ====
Having a unique Bitcoin currency sign will allow typographers to add their currency sign design in their fonts. This is similar as implementing support for the euro sign. Each font has its own version of the euro sign that fits with the style observed in the characters in the rest of the fonts of their typefaces. Note that the Unicode Consortium does not endorse Bitcoin in any way by assigning a Unicode character code, however, having a Unicode for the Bitcoin sign will also be good for PR and help having Bitcoin be taken more seriously.

==== Requirements and criteria ====

A reference Bitcoin sign could/should/must be:
* recognizable as a [https://secure.wikimedia.org/wikipedia/en/wiki/Currency_sign currency sign] such as $ € ¥ £ ¢ (e.g. with one or two vertical or horzontal bars)
* not confusing with existing currency sign such as Thai Bath ฿
* build from recognizable existing characters found on most [https://secure.wikimedia.org/wikipedia/en/wiki/Keyboard_layout#United_States QWERTY keyboards] such as bar |, minus -, hash # and/or capital B referring to currencies and '''B'''itcoin
* easy to use in handwriting
* easy to compose with one or more [https://help.ubuntu.com/community/GtkComposeTable#The%20Gtk%20Compose%20Table compose seuquences] that are still free and refer to the elements recognizable in the sign (For example the euro sign can be composed from = and C even though the = and C are not part of how it is pronounced.)
* ''possible'' to implement in [https://secure.wikimedia.org/wikipedia/en/wiki/Serif serif and sans-serif] (Most of the [http://www.unicode.org/charts/PDF/U20A0.pdf Unicode reference implementations] are made with serifs but sans-serif also exist in sans-serif fonts. So a reference implementation in serif to what is found in the PDF is preferred.)
* ''possible'' to implement in regular, italic, bold and bold italic (for sans-serif the italic will simply be a slanted version)
* in [https://secure.wikimedia.org/wikipedia/en/wiki/SVG SVG] and use this [http://pastebin.com/raw.php?i=FVY8W1W3 template] (save as bitcoin-sign-20110719-template.svg) with updated metadata and public domain or similar free/open/libre license

Note that a reference Bitcoin sign will only be used as a reference by the Unicode Consortium and it is up to typographers to implement their version matching the style of their typefaces and fonts.

==== Submissions====

It is possible to submit proposals for a '''reference implementation''' below until (community must determine date). They will be judged by (community must form committee for this). If you have problems submitting your design, ask a friend with knowledge on editing wikipedia for help.

=== Existing Unicode symbol ===

There is a discussion over [http://www.bitcoin.org/smf/index.php?topic=369.0 which Unicode symbol might be the best suited] for bitcoin.

To type Unicode characters, refer to:

* [[Microsoft Windows Unicode Input]]
* [[How to easily type the circled B symbol on a Mac]]

It has led to the following options:

Note that a currency sign is more complex than creating a logo as will be explained below.

[[File:Example-unicode-reference-currency-signs.png|256px|thumb|right|Examples of Unicode currency sign reference glyphs]]

=== New Unicode symbol ===

In some discussions [https://forum.bitcoin.org/index.php?topic=41.0 41], [https://forum.bitcoin.org/index.php?topic=369.0 369] and [https://forum.bitcoin.org/index.php?topic=7215.0 7215] on the bitcoin forum several designs of an official Bitcoin sign have been proposed. This section on the Wiki is intended to streamline the process of arriving at an official Bitcoin currency sign with its own Unicode character code.

==== Goal ====
Having a unique Bitcoin currency sign will allow typographers to add their currency sign design in their fonts. This is similar as implementing support for the euro sign. Each font has its own version of the euro sign that fits with the style observed in the characters in the rest of the fonts of their typefaces. Note that the Unicode Consortium does not endorse Bitcoin in any way by assigning a Unicode character code, however, having a Unicode for the Bitcoin sign will also be good for PR and help having Bitcoin be taken more seriously.

==== Requirements and criteria ====

A reference Bitcoin sign could/should/must be:
* recognizable as a [https://secure.wikimedia.org/wikipedia/en/wiki/Currency_sign currency sign] such as $ € ¥ £ ¢ (e.g. with one or two vertical or horzontal bars)
* not confusing with existing currency sign such as Thai Bath ฿
* build from recognizable existing characters found on most [https://secure.wikimedia.org/wikipedia/en/wiki/Keyboard_layout#United_States QWERTY keyboards] such as bar |, minus -, hash # and/or capital B referring to currencies and '''B'''itcoin
* easy to use in handwriting
* easy to compose with one or more [https://help.ubuntu.com/community/GtkComposeTable#The%20Gtk%20Compose%20Table compose seuquences] that are still free and refer to the elements recognizable in the sign (For example the euro sign can be composed from = and C even though the = and C are not part of how it is pronounced.)
* ''possible'' to implement in [https://secure.wikimedia.org/wikipedia/en/wiki/Serif serif and sans-serif] (Most of the [http://www.unicode.org/charts/PDF/U20A0.pdf Unicode reference implementations] are made with serifs but sans-serif also exist in sans-serif fonts. So a reference implementation in serif to what is found in the PDF is preferred.)
* ''possible'' to implement in regular, italic, bold and bold italic (for sans-serif the italic will simply be a slanted version)
* in [https://secure.wikimedia.org/wikipedia/en/wiki/SVG SVG] and use this [http://pastebin.com/raw.php?i=FVY8W1W3 template] (save as bitcoin-sign-20110719-template.svg) with updated metadata and public domain or similar free/open/libre license

Note that a reference Bitcoin sign will only be used as a reference by the Unicode Consortium and it is up to typographers to implement their version matching the style of their typefaces and fonts.

==== Submissions====

It is possible to submit proposals for a '''reference implementation''' below until (community must determine date). They will be judged by (community must form committee for this). If you have problems submitting your design, ask a friend with knowledge on editing wikipedia for help.

=== Existing Unicode symbol ===

There is a discussion over [http://www.bitcoin.org/smf/index.php?topic=369.0 which Unicode symbol might be the best suited] for bitcoin.

To type Unicode characters, refer to:

* [[Microsoft Windows Unicode Input]]
* [[How to easily type the circled B symbol on a Mac]]

It has led to the following options:
