Bitcoin symbol

Kenshirriff: fix typo

By far the most commonly used symbol for Bitcoin is [[:{{ns:File}}:Btc-sans.png|{{BTC}}]], a capital letter '''B''' with two vertical lines "going through" it, though the lines are only visible at the top and bottom. This symbol was created 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>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. The Bitcoin sign was accepted for Unicode in November 2015<ref>https://twitter.com/ken_lunde/status/661351862155669506</ref> and completed the Unicode process in 2017.

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.

== 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>

==== Font ====
As few fonts include the Bitcoin symbol, a special font was created by [[User:Theymos]], originally for the [[BitcoinTalk]] forum<ref>https://bitcointalk.org/index.php?topic=88647</ref>. The font consists of ''only'' the Bitcoin symbol 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 this Bitcoin Wiki.

Kenshirriff: Typo

Reward types & explanation:
* '''CPPSRB''' - Capped Pay Per Share with Recent Backpay. [http://eligius.st/wiki/index.php/Capped_PPS_with_Recent_Backpay]
* '''DGM''' - Double Geometric Method. A hybrid between PPLNS and Geometric reward types that enables to operator to absorb some of the variance risk. Operator receives portion of payout on short rounds and returns it on longer rounds to normalize payments. [https://bitcointalk.org/index.php?topic=39497.0]
* '''ESMPPS''' - Equalized Shared Maximum Pay Per Share. Like SMPPS, but equalizes payments fairly among all those who are owed. [http://forum.bitcoin.org/index.php?topic=12181.msg378851#msg378851]
* '''POT''' - Pay On Target. A high variance PPS variant that pays on the difficulty of work returned to pool rather than the difficulty of work served by pool [https://bitcointalk.org/index.php?topic=131376.0]
* '''PPLNS''' - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries.
* '''PPLNSG''' - Pay Per Last N Groups (or shifts). Similar to PPLNS, but shares are grouped into "shifts" which are paid as a whole.
* '''PPS''' - Pay Per Share. Each submitted share is worth certain amount of BC. Since finding a block requires <current difficulty> shares ''on average'', a PPS method with 0% fee would be 25 BTC divided by <current difficulty>. It is risky for pool operators, hence the fee is highest.
* '''Prop.''' - Proportional. When block is found, the reward is distributed among all workers proportionally to how much shares each of them has found.
* '''RSMPPS''' - Recent Shared Maximum Pay Per Share. Like SMPPS, but system aims to prioritize the most recent miners first. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]
* '''Score''' - Score based system: a proportional reward, but weighed by time submitted. Each submitted share is worth more in the function of time ''t'' since start of current round. For each share score is updated by: score += exp(t/C). This makes later shares worth much more than earlier shares, thus the miner's score quickly diminishes when they stop mining on the pool. Rewards are calculated proportionally to scores (and not to shares). (at slush's pool C=300 seconds, and every hour scores are normalized)
* '''SMPPS''' - Shared Maximum Pay Per Share. Like Pay Per Share, but never pays more than the pool earns. [http://eligius.st/wiki/index.php/Shared_Maximum_PPS]
[http://eligius.st/~luke-jr/samples/800MH-3/ Visual examples of the various payout methods]

<ref name="hashrate2">Note that pool hashrate is largely irrelevant but can be seen as a popularity measurement.
