|warning=scam,This company attempted to market mining hardware that was claimed to use their own chips - however the hardware even on paper was highly inefficient and overpriced (being sold by pre-order) by the time it was announced. At one point the company suggested free units for review by interested parties as long as they would post immediate review threads on BitcoinTalk. This has since been regarded as an attempt to bolster credibility. The company's website is no longer in operation and BitcoinTalk forum accounts inactive.

|warning=scam,This company attempted to market mining hardware that was claimed to use their own chips - however the hardware even on paper was highly inefficient and overpriced (being sold by pre-order) by the time it was announced. At one point the company suggested free units for review by interested parties as long as they would post immediate review threads on BitcoinTalk. This has since been regarded as an attempt to bolster credibility. The company's website is no longer in operation and BitcoinTalk forum accounts inactive.

TheRealSteve: /* ASIC */ updated Antminer S5, added Antminer S5+, S7

{{seealso|Non-specialized hardware comparison}}
Below are statistics about the Bitcoin [[Mining]] performance of [[ASIC]] hardware and '''only includes specialized equipment that has been shipped.'''

GPUs, CPUs and other hardware not specifically designed for Bitcoin mining can be found in the [[Non-specialized_hardware_comparison]].

'''Notes:'''
* Mhash/s = millions [[hash per second|hashes per second]] ([[Protocol_specification#Hashes|double sha256]] raw speed performance; may not be very energy efficient with some models)
* Mhash/J = millions hashes per joule (energy efficiency; 1 joule of energy is 1 watt during 1 second: 1 J = 1 W*s)
* W = watt (maximum power consumption, i.e. energy per unit of time: 1 W = 1 J/s)

|warning=scam,This company attempted to market mining hardware that was claimed to use their own chips - however the hardware even on paper was highly inefficient and overpriced (being sold by pre-order) by the time it was announced. At one point the company suggested free units for review by interested parties as long as they would post immediate review threads on BitcoinTalk. This has since been regarded as an attempt to bolster credibility. The company's website is no longer in operation and BitcoinTalk forum accounts inactive.

Controlled supply

TheRealSteve: /* Spendable Supply */ added note about gettxoutsetinfo

<blockquote>A fixed money supply, or a supply altered only in accord with objective and calculable criteria, is a necessary condition to a meaningful just price of money.<ref>[https://www.scribd.com/doc/138347161/Bernard-W-Dempsey-1903-1960-Interest-and-Usury-With-an-Introduction-by-Joseph-a-Schumpeter-1948#page220 <i>Interest and Usury</i> p. 220] by [https://www.jstor.org/stable/29769582 Fr.

<p align="right">—[https://www.jstor.org/stable/29769582 Fr. Bernard W. Dempsey, S.J.] (1903-1960)</p></blockquote>

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The
[[wikipedia:monetary base|monetary base]] is controlled by a central bank. In the United States, the [[wikipedia:Federal Reserve System|Fed]] increases the monetary base by issuing currency, increasing the amount banks have on reserve, and more recently, printing money electronically in a process called [[wikipedia:Quantitative Easing|Quantitative Easing]].

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

==Currency with Finite Supply==
[[Image:Controlled supply-block reward halving.png|160px|thumb|right| Block reward halving]]
[[Image:Controlled supply-supply over block height.png|160px|thumb|right| Controlled supply]]
Bitcoins are created each time a user discovers a new [[block]].
The rate of block creation is approximately constant over time: 6 per hour. The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of bitcoins in existence will never exceed 21 million.<ref>[http://www.bitcointalk.org/index.php?topic=3366.msg47522#msg47522 21 million cap]</ref> Speculated justifications for the unintuitive value "21 million" are: it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number.

[[File:ControlledSupply.gif]]

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called [[Mining|''Miners'']].

==Projected Bitcoins Short Term ==
This chart shows the number of bitcoins that will exist in the near future. The ''Year'' is a forecast and may be slightly off.

==Projected Bitcoins Long Term ==
[[Image:Controlled supply-timeline estimation.png|160px|thumb|right| Supply timeline estimation]]
Because the number of bitcoins created each time a user discovers a new block - the block reward - is halved based on a fixed interval of blocks, and the time it takes on average to discover a block can vary based on [[mining]] power and the network [[difficulty]], the exact time when the block reward is halved can vary as well. Consequently, the time the last Bitcoin will be created will also vary, and is subject to speculation based on assumptions.

If the mining power had remained constant since the first Bitcoin was mined, the last Bitcoin would have been mined on October 8th, 2140. Due to the mining power having increased overall over time, as of block 367,500 - assuming mining power remains constant from that block forward - the last Bitcoin would be mined on May 7th, 2140.

As it is very difficulty to predict how mining power will evolve going into the future - i.e. whether technological progress will continue to make hardware faster or whether mining will hit a a technological wall, or whether or not faster methods of calculation will be discovered - putting an exact date or even year on this event is difficult as well.

The total number of bitcoins, as mentioned earlier, will tend toward 21 million. Due to a technical limitation in the data structure of the blockchain - specifically of the [[Transaction#general_format_.28inside_a_block.29_of_each_output_of_a_transaction_-_Txout|transaction output]], this exact value is 20,999,999.9769 bitcoin. Should this technical limitation is adjusted, the total number will still only be a maximum of 21 million.

''Note: The number of bitcoins are presented in a floating point format. However, these values are based on the number of satoshi per block originally in integer format to prevent compounding error.''

==Spendable Supply==
The theoretical total number of bitcoins, 21 million, should not be confused with the total spendable supply. The total spendable supply is always lower than the theoretical total supply, and is subject to accidental loss, willful destruction, and technical peculiarities.

One way to see a part of the destruction of coin is by collecting a sum of all unspent transaction outputs, using a [[API reference (JSON-RPC)|Bitcoin RPC]] command <code>gettxoutsetinfo</code>. The ''total_amount'' value returned is the sum of all outputs that the client deems technically spendable but not currently spent. Note however that this does not take into account outputs that are exceedingly unlikely to be spent as is the case in loss and destruction via constructed addresses, for example.
===Loss of bitcoin===
Bitcoins may be lost if the conditions required to spend them are no longer known. For example, if you made a transaction to an [[address]] that requires a private key in order to spend those bitcoins further, had written that private key down on a piece of paper, but that piece of paper was lost. In this case, that bitcoin may also be considered lost, as the odds of randomly finding a matching private key are such that it is generally considered impossible.

===Willful destruction of bitcoin===
Bitcoins may also be willfully 'destroyed' - for example by attaching conditions that make it impossible to spend them.

A common method is to send bitcoin to an address that was constructed and only made to pass validity checks, but for which no private key is actually known. An example of such an address is "1BitcoinEaterAddressDontSendf59kuE", where the last "f59kuE" is text to make the preceding constructed text pass validation. Finding a matching private key is, again, generally considered impossible. For an example of how difficult this would be, see [[Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses|Vanitygen]].

Another common method is to send bitcoin in a transaction where the conditions for spending are not just unfathomably unlikely, but literally impossible to meet. For example, a transaction that is made [[Script#Provably_Unspendable.2FPrunable_Outputs|provably unspendable using OP_RETURN]], or uses script operations that requires the user to prove that 1+1 equals 3.

A lesser known method is to send bitcoin to an address based on private key that is outside the [[Private_key#Range_of_valid_ECDSA_private_keys|range of valid ECDSA private keys]]. For example, the address 16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM has a known matching private key of value 0 (zero), which is outside the valid range.

===Technical peculiarities preventing spending of bitcoin===
There are also technical peculiarities that prevent the spending of some bitcoin.

The first {{btc}}50, included in the [[genesis block]], cannot be spent as its transaction is not in the global database.

In older versions of the bitcoin reference code, a miner could make their coinbase transaction (block reward) have the exact same ID as used in a previous block<ref>https://github.com/bitcoin/bitcoin/issues/612</ref>. This effectively caused the previous block reward to become unspendable. Two known such cases<ref>{{cite tx|e3bf3d07d4b0375638d5f1db5255fe07ba2c4cb067cd81b84ee974b6585fb468|used in blocks 91722 and 91880}}</ref><ref>{{cite tx|d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599|used in blocks 91812 and 91842</ref> are left as special cases in the code<ref>https://github.com/bitcoin/bitcoin/commit/ab91bf39b7c11e9c86bb2043c24f0f377f1cf514</ref> as part of [[BIP 0030]] changes that fixed this issue. These transactions were {{btc}}50 each.

==Money Supply==
While the number of bitcoins in existence will never exceed 21 million, the [[wikipedia:money supply|money supply]] of bitcoins can exceed 21 million due to [[wikipedia:Fractional-reserve Banking|Fractional-reserve Banking]].

==Deflation==

Because the monetary base of bitcoins cannot be expanded, the currency would be subject to severe deflation if it becomes widely used.
Keynesian economists argue that [[Deflationary spiral|deflation]] is bad for an economy because it incentivises individuals and businesses to save money rather than invest in businesses and create jobs. The [[wikipedia:Austrian school|Austrian school]] of thought counters this criticism, claiming that as deflation occurs in all stages of production, entrepreneurs who invest benefit from it. As a result, profit ratios tend to stay the same and only their magnitudes change. In other words, in a deflationary environment, goods and services decrease in price, but at the same time the cost for the production of these goods and services tend to decrease proportionally, effectively not affecting profits. Price deflation encourages an increase in hoarding — hence savings — which in turn tends to lower interest rates and increase the incentive for entrepreneurs to invest in projects of longer term.

Bitcoin symbol

TheRealSteve: /* Currency Sign */ inclusion examples

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'''.

== 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 <sup>[still true?]</sup>. This application would request ISO 4217 standard to support XBT.

== Currency Sign ==

{{BTC}} <sup>(here rendered using a webfont -- you will see "BTC" if your browser does not support webfonts)</sup> has been the standard currency sign for BTC for a long time. This symbol can ''sort of'' be represented using existing Unicode features as (B⃦), but this symbol is completely broken on many devices/browsers, and ''at best'' it looks quite off. Some existing Unicode symbols have been proposed as alternatives, 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 creating an official 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 ===

{{outdated|section}}

In some discussions on topics [https://bitcointalk.org/index.php?topic=41.0 41], [https://bitcointalk.org/index.php?topic=369.0 369] and [https://bitcointalk.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 to 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, by having an official Unicode Bitcoin's perception of legitimacy will increase.

==== 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 horizontal bars)
* distinct from existing currency signs such as the Thai Baht, ฿
* built 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 sequences] 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 <tt>bitcoin-sign-20110719-template.svg</tt>) 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.

=== 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.

A package including a high resolution raster image with transparency (PNG), vector image (SVG) and TrueType font (TTF) is available<ref>http://www.filedropper.com/bitcoinsymbol</ref>

==== 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 <i class="fa fa-btc"></i>0.01 to ...</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.

Sample HTML code:
<nowiki> @font-face { font-family: BTC; src: url(BTC.ttf); }
...
Please send <span style="font-family:BTC, sans-serif">BTC</span>0.01 to ...</nowiki>

This article lists Bitcoin-related press from the project's creation through October 2011. Since that time, due to the increased frequency of published articles, a [http://bitcointalk.org/index.php?board=77.0 Press forum board] was created on the BitcoinTalk Forum to allow the wider Bitcoin community to share articles as they are discovered.

Talk:Mining hardware comparison

2015-09-02T21:17:26Z

TheRealSteve: /* Sorting does not work for the table */

{{archive}}__TOC__
== Pre-orders ==

Listing of hardware that can only be pre-ordered should be discouraged. Listing of vaporware should be disallowed. In either of these cases, if you have editing capabilities, consider removing the listing. While everyone should do their due diligence before making a purchase - especially in pre-order cases - we can all help to keep things a bit more tidy by only having a comparison of actual, existing hardware that ships now or has shipped in the past.

If there is disagreement on the above, perhaps we can agree to have a separate section for pre-orders and vaporware, which could then carry an additional warning. Open for discussion :) [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 14:33, 7 February 2015 (UTC)

== Why was my hardware removed? ==

If your hardware was removed from the mining hardware comparison list, this section will attempt to explain the possible reason why - though always check the edit summary (see "View history") for pointers.

Although there is no set policy for allowing or disallowing hardware to be listed in the hardware comparison at this time, it is generally frowned upon to list hardware that doesn't exist (yet) - which may subsequently be deleted by anybody with editing rights to this wiki.

The "innocent until proven guilty" approach does not work in this field, due to the many bad actors that will take advantage of such an approach. As a result, the approach is that any listing is treated at first as benign and discussed (here or in online forums) until an apparent consensus is reached. At that point, your listing may have been relegated to a "guilty until proven innocent" status.

The community cannot always prove a bad actor. For example, if you have renders of miners on your website/in your store, but no actual photos, you can always claim that the images you use are just stand-ins and that you can't release any actual photographs yet because the hardware is being finalized and so forth and so on. At that point, however, it is essentially non-existent hardware that should not be listed. If, on the other hand, there is actual hardware on hand, there's little reason to be using renders.

The onus is thus on you you to attempt to prove that you are not a bad actor. There's plenty of ways in which you can do so:
* If you are taking pre-orders: don't - a comparison between existing hardware and hardware that effectively doesn't exist, is no comparison at all.
* Rather than providing renders or photoshopped images, provide actual photography of your hardware. The more photos, the better.
* If you are integrating a 3rd party's chip, specify which chip. If you are integrating your own chip design, try to provide details on its design.
* If challenged in online discussion platforms to show it hashing, provide a video of the hardware mining with a verifiable (public) pool statistics page.
* If currently only accepting Bitcoin payments, consider adding other payment options - PayPal, credit card, etc. If these are not an option, or not desirable, consider adding a trusted escrow agent option.
These are options that range from simple to more involved in terms of effort, while each significantly raises the bar for still being called a bad actor.

Ultimately, you may have to have a third party review one of your miners in order to build your credibility. This could be one of your customers, or it could be a trusted member of online discussion forums, or popular hardware review websites. This does not necessarily require you to send hardware for free - making it available 'on loan' is also perfectly acceptable, as would be demonstrating in person. While certainly the option that requires the most effort (and possibly expenses), this does increase your reputation as being a good actor not just for that particular hardware, but any other hardware you may be selling, which may make this option a good step as a business going forward.

If at any point you dispute a removal, your first step should be to simply add your hardware back to the list, and the second step should be to open up dialog through this talk page, by using the "Add topic" link at the top to start a new discussion, or simply reply to an existing discussion that pertains to your case. If you provide good arguments as to why your listing should remain, it is unlikely to be removed again.

There is this list: [https://bitcointalk.org/index.php?topic=464496.0=edit Bitcoin Talk Forum] - [[User:Ezeminer|Ezeminer]] 9:46 1 April 2015 UTC
:I know, it's mine ;) The BitcoinTalk Forum was the best place to put that information when I posted it - slowly but surely, I think the wiki is becoming that place. I'll move it over at some point, but not any time soon. I'll probably keep the thread around in a slimmed down version. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 01:32, 2 April 2015 (UTC)
::Funny I thought that was by a different user :D - [[User:Ezeminer|Ezeminer]] 20:00, 2 April 2015 (UTC)

== Sorting does not work for the table ==

The table has

class="wikitable sortable"

set, yet it isn't sortable. Pasting the table's code to the [https://meta.wikimedia.org/w/index.php?title=Meta:Sandbox&action=edit WikiMedia sandbox] shows that it does allow sorting there, but not here on Bitcoin wiki. [[User:Geremia|Geremia]] ([[User talk:Geremia|talk]]) 17:25, 13 March 2015 (UTC)
: Yeah, I noticed that earlier as well. I think the javascript that enables sorting is missing altogether. Might raise this on IRC :) [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 20:54, 13 March 2015 (UTC)

Talk:Controlled supply

2015-09-02T00:35:24Z

TheRealSteve: /* Actual Supply is Different From The Tables Here */

{{WikiProject|Economics|quality=C|importance=TOP}}
{{WikiProject|Protocol|quality=C|importance=TOP}}
{{WikiProject|Mining|quality=C|importance=TOP}}
== Do not Resurrect That Stupid Graph ==
Please see my points over at [[File_talk:Total_bitcoins_over_time_graph.png]] which describe why I deleted the graph, and description of a suitable alternative. Seriously, the amount of misleading information that prior graph has disseminated into the public is horrorshow-enormous. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 07:11, 14 September 2014 (UTC)

== Actual Supply is Different From The Tables Here ==
Note that the actual supply is different than what is listed on these graphs due to provably destroyed coins, duplicate coinbase, and underpays; this should be accounted-for in the graphs. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 16:32, 16 September 2014 (UTC)
:I'm not sure if 'destroyed' coins should be taken into account. While they may never become part of transactions again, they were at least created. Duplicate coinbase and underpays are a different matter. I'd like to take these into account in at least the description in one of my graphs (see the talk page for the deleted graph), but would also like to see some source material from which to glean actual numbers. If you, or anybody else, can help out with this, it would be appreciated. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 21:48, 12 April 2015 (UTC)
:I'd still like to see some examples of further technical peculiarities that make existing bitcoin unspendable, as well as examples of bitcoin that actually entered into existence when it shouldn't have (thus raising the maximum), didn't enter into existence when they should have (thus lowering the maximum) and any other case that isn't simple loss or willful destruction. There's a section on this now, so by all means, add there directly [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 12:36, 20 July 2015 (UTC)
:: The Genesis block is unspendable due to an explicit code exception. Duplicate codebases account for another.. 25 BTC or so I think, plus fees. Destroyed bitcoins like OP_RETURN slowly grow total destroyed bitcoins over time as well. You can see this difference by running: bitcoin-cli gettxoutsetinfo and subtracting the total_amount from a calculated total, from genesis. At the moment, for example, total bitcoins that can ever exist if every lost bitcoin privkey is magically found again is: 20999839.77085749 BTC. {{unsigned|Midnightmagic|11:26, 30 August 2015}}
::: Ah, that command is a good one. I'll see if I can add that to the relevant section in some understandable way. Thanks! [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 00:35, 2 September 2015 (UTC)

== Projected Bitcoins (Long Term) - the numbers ==

The Projected Bitcoins Long Term table in the page uses [[Units|Bitcoin]] unit representation as a floating point number with an 8-digit precision to convey the actual number in [[Satoshi (unit)|satoshi]], which has an integer representation inside the [[Bitcoin Core|satoshi client]].

Each of the values is based on the actual number of satoshi rewarded per block. This reward halves every 210,000 blocks.[https://github.com/bitcoin/bitcoin/blob/master/src/main.cpp#L1179] This halving presents a potential point of confusion; at some point the reward would be 610,351.5 satoshi - which at {{as of|2015|04|04}} cannot exist in the satoshi client's fixed point arithmetic limit.<br />
The value is, instead, truncated to 610,351 satoshi. The total number of satoshi generated during that reward era is thus not <tt>210,000 * 610,351.5 = 128,173,815,000 (<span class="btc">BTC</span>1,281.73815000)</tt>, but <tt>210,000 * 610,351 = 128,173,710,000 (<span class="btc">BTC</span>1,281.73710000)</tt>. The same problem presents itself with any subsequent reward eras .<br />
An earlier version of the table in this page had a single satoshi error in some of the values, likely due to related floating point accuracy issues.[http://www.reddit.com/r/Bitcoin/comments/31g89l/rounding_error_in_the_wiki/]

At the actual last round there should be a total of <tt><span class="btc">BTC</span>20,999,999.97690000</tt>.<br />
If using floating point math throughout, depending on the accuracy and behavior of the floating point calculations, this could end up being calculated as <tt><span class="btc">BTC</span>20999999.99877760</tt>, or a difference of <tt><span class="btc">BTC</span>0.02187764</tt>.<br />
The floating point math approach will tend toward a total supply of <tt><span class="btc">BTC</span>21,000,000</tt>, and a difference from the actual current maximum of <tt><span class="btc">BTC</span>0.0231</tt>.

For technical purposes, the total supply should be noted as <tt><span class="btc">BTC</span>20,999,999.97690</tt> with a reminder that this depends on the current fixed point arithmetic. For colloquial use, <tt><span class="btc">BTC</span>21,000,000</tt> should be acceptable. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 22:01, 4 April 2015 (UTC)

== Projected Bitcoins (Long Term) 'Years' column removal ==

I've finally removed the Years column from the "Projected Bitcoins Long Term" table. There's multiple arguments in favor of this: 1. The existing format was decimal years, which aren't very layperson friendly. 2. Laypersons may be misled to believe these year/date values are set in stone, when they are not. For relevant discussion, see the arguments regarding an earlier graph which I can only presume (as the file was deleted) was equally misleading, and this reddit comment thread (disclaimer: I'm a participant in that thread): https://www.reddit.com/r/Bitcoin/comments/31g89l/rounding_error_in_the_wiki/ . If anybody wants to put year/date numbers back in: it's a wiki, go ahead, but I'd appreciate an outline of the arguments in favor in response here :) [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 22:11, 30 July 2015 (UTC)

Vanitygen

2015-08-29T01:23:17Z

TheRealSteve: /* Expected keysearch rate */ +HD5870, GTX970

'''Vanitygen''' is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjO.
Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen. It is typical, and takes about 10 sec to finish, using a Core 2 Duo E6600 CPU on x86-64 Linux:
<syntaxhighlight lang="bash">
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
</syntaxhighlight>

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client. Oclvanityminer can be used to automatically claim bounties on sites such as [[User:ThePiachu|ThePiachu]]'s [[Vanity Pool]].

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Radeon 58XX outperforms Radeon 69XX by a very comfortable margin. Oclvanitygen is sensitive to integer multiply throughput, and Radeon 58XX can multiply concurrently with other operations. At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.

== Difficulty of finding a vanity ==
The difficult of finding a vanity address depends on its exact structure (leading letters and numbers) and how likely such an output is given the algorithms involved, which can consist of several pivots where the difficulty suddenly changes.
{| class="wikitable"
|-

|-
| 111111 || 1,099,511,627,776 || A special case, leading numbers 1 (one) is especially difficult.
|}

== Use of vanitygen to try to attack addresses ==
Using vanitygen you might think that you would be able to find the private key for a given address. In practice, this is considered impossible. Given that the difficulty increases exponentially the longer your vanity is, so does the average time required to find that vanity. The example table below shows how an increasingly complex vanity affects the difficulty and average time required to find a match only for that vanity, let alone the full address, for a machine capable of looking through 1 million keys per second.

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Radeon 58XX outperforms Radeon 69XX by a very comfortable margin. Oclvanitygen is sensitive to integer multiply throughput, and Radeon 58XX can multiply concurrently with other operations. At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.

== Difficulty of finding a vanity ==
The difficult of finding a vanity address depends on its exact structure (leading letters and numbers) and how likely such an output is given the algorithms involved, which can consist of several pivots where the difficulty suddenly changes.

== Use of vanitygen to try to attack addresses ==
Using vanitygen you might think that you would be able to find the private key for a given address. In practice, this is considered impossible. Given that the difficulty increases exponentially the longer your vanity is, so does the average time required to find that vanity. The example table below shows how an increasingly complex vanity affects the difficulty and average time required to find a match only for that vanity, let alone the full address, for a machine capable of looking through 1 million keys per second.

Getblocktemplate

2015-08-22T12:15:56Z

TheRealSteve: /* How to build block header */

getblocktemplate is the new decentralized Bitcoin mining protocol, openly developed by the Bitcoin community over mid 2012.
It supercedes the old [[getwork]] mining protocol.

{{TOC limit|3}}

==Why change something that works?==

===Decentralization===
The original getwork mining protocol simply issues block headers for a miner to solve.
The miner is kept in the dark as to what is actually in this block, and has no influence over it.
In effect, the authority of the miner to decide which transactions are accepted, etc, is all transferred blindly to the pool operator.
A corrupt (or compromised) pool operator could use the combined hash power of all the miners to execute double spend attacks or other similar attacks.

getblocktemplate moves block creation to the miner, while giving pools a way to set down the rules for participation.
While pools can do just as much as they could before by expressing it in these rules, miners can not be kept in the dark and are enabled to freely choose what they participate in mining.
This improves the security of the Bitcoin network by making blocks decentralized again.

===ASICs===
The original getwork protocol only provides a single block header, which is sufficient for a total of about 4 GH of mining.
With the "rollntime" extension, this can be extended to 4 GH *per second*, but even that is far from sufficient for the next generation of mining equipment (ASICs) which are capable of 1000 GH/s on the high end.

By moving block creation to the miners, they are enabled to create as much work as they need locally, thus overcoming this limitation.

===Scalability===
Due to scalability problems, bitcoind's JSON-RPC stack has not been able to keep up with the hashrates needed for solo mining today.
Since getblocktemplate drastically reduces the load required to a single request per new block on the network, direct solo mining on bitcoind is again possible.
Poolservers likewise benefit from having to meet much lower demands of miners who can make their own blocks.

===Extensible===
The original getwork protocol was designed in a way that was very incompatible with extensions.
As a result, as new functionality was needed, extensions were "hacked in" out-of-band using HTTP headers.
getblocktemplate is designed from the start to be flexible for future extensions, and the [[BIP 0023|BIP 23]] specification already covers how the established getwork extensions can be implemented cleanly, regardless of transport protocol.

===For pool operators===
See also: [[Poolservers]]

If you are implementing your own pool server, see the [[#Poolserver software|section for poolserver development]].

===For developers===
====Mining software====
=====Using libblkmaker (C library)=====
If your miner can include C libraries, you can harness [https://gitlab.com/bitcoin/libblkmaker libblkmaker] to do all the GBT interpretation for you:
all your miner needs to do then is handle the networking (libblkmaker can prepare the JSON for you) and ask libblkmaker for data (block headers to search).
Note that libblkmaker does not provide a SHA256 implementation, and your miner needs to provide one for it to work.
libblkmaker currently only supports the Jansson JSON library, but was designed such that it can easily be ported to others;
[[User:Luke-jr|Luke Dashjr]] is willing to do this porting to other JSON libraries free of charge on request.

=====Using python-blkmaker=====
If your miner is written in Python, you can harness [https://gitlab.com/bitcoin/python-blkmaker python-blkmaker], a native Python port of libblkmaker, to do all the GBT interpretation for you:
all your miner needs to do then is handle the networking (python-blkmaker can prepare the JSON for you) and ask the blkmaker module for data (block headers to search).
A short example Python script is included that finds a prepared share using CPU mining.

=====From scratch=====
======Miner requests block template======

To start participating, the miner contacts the pool and requests an initial template:
{"id": 0, "method": "getblocktemplate", "params": [{"capabilities": ["coinbasetxn", "workid", "coinbase/append"]}]}

The server will respond with the full details needed to immediately begin mining blocks:
{
"error": null,
"result": {
"coinbasetxn": {
"data": "0100000001000000000000000000000000000000000000000000000000000000
0000000000ffffffff1302955d0f00456c6967697573005047dc66085fffffffff02fff1052a01
0000001976a9144ebeb1cd26d6227635828d60d3e0ed7d0da248fb88ac01000000000000001976
a9147c866aee1fa2f3b3d5effad576df3dbf1f07475588ac00000000"
},
"previousblockhash": "000000004d424dec1c660a68456b8271d09628a80cc62583e5904f5894a2483c",
"transactions": [],
"expires": 120,
"target": "00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
"longpollid": "some gibberish",
"height": 23957,
"version": 2,
"curtime": 1346886758,
"mutable": ["coinbase/append"],
"bits": "ffff001d"
},
"id": 0
}

======How to build coinbase transaction======
If the pool allows the "coinbase/append" mutation by including it in the "mutable" key, you can rebuild the coinbase transaction to append any data your miner wants, such as an extranonce - you can use as much space as you need so long as the coinbase data does not overflow the 100 byte hard limit.
If the server does *not* allow "coinbase/append", or you don't care to change it, you can skip this step entirely :)

The coinbase data always begins after exactly 42 bytes of the coinbase transaction.
The 42nd byte (that is, the byte immediately before the data) is the length of the data.
So when/if you want to add on to the coinbase data, simply insert it 42+DataLen bytes into the transaction, and increment the 42nd byte by the length of your inserted data.

Python example:
import binascii
coinbase = binascii.a2b_hex(template['coinbasetxn']['data'])
extradata = b'my block'
# The following can be done better in both Python 2 and Python 3, but this way works with both
origLen = ord(coinbase[41:42])
newLen = origLen + len(extradata)
coinbase = coinbase[0:41] + chr(newLen).encode('ascii') + coinbase[42:42 + origLen] + extradata + coinbase[42 + origLen:]

======How to build merkle root======
Collect your coinbase transaction (modified or not) at the front of the "transactions" list provided by the server.
Apply a double-SHA256 hash to each transaction in the list.

Now, as long as the list has more than 1 hash remaining, go through each pair and hash them together.
That is, concatenate the first two, double-SHA256 that, repeat for the next two, and so on.
If you encounter an odd pair (that is, the hash list ends with a single item and no pairing), concatenate it with itself and hash that.
Continue to do that until there is only one hash left:
that is your merkle root.

Python example:
import hashlib
def dblsha(data):
return hashlib.sha256(hashlib.sha256(data).digest()).digest()

txnlist = [coinbase] + [binascii.a2b_hex(a['data']) for a in template['transactions']]
merklehashes = [dblsha(t) for t in txnlist]
while len(merklehashes) > 1:
if len(merklehashes) % 2:
merklehashes.append(merklehashes[-1])
merklehashes = [dblsha(merklehashes[i] + merklehashes[i + 1]) for i in range(0, len(merklehashes), 2)]
merkleroot = merklehashes[0]

======How to build block header======
Assemble the block header as laid out in the Bitcoin [[block hashing algorithm]], using the data provided in the block template along with your very own merkle root.
Note that miners are expected to check the "version" number, and should not create blocks with versions they do not understand unless the server instructs them to do so with the "version/force" or "version/reduce" mutations - you don't need to support those, but if you don't support the version the server has provided, understand that the server may reject submissions if they don't meet some unknown future rules.
As of this time, the current Bitcoin block version is 3.

Python example:
import struct
blkheader = struct.pack('<I', template['version']) + \
binascii.a2b_hex(template['previousblockhash']) + \
merkleroot + \
struct.pack('<I', template['curtime']) + \
binascii.a2b_hex(template['bits']) + \
b'NONC'

======While you're mining======
Since you're making all the blocks yourself, you really don't ever need to get another template... until it's invalid.
Generally, it's a good idea to refresh more often anyway to get more transactions, but it's better to let the pool decide when to do that, since it knows what's changed in the meantime already.

If your template included a "longpollid" key, you can queue a request for a new template to be executed as soon as the pool decides you should change.
This is the same as any other template request, except that you include the "longpollid" parameter that the pool provided in your request.
If there is already a new template, the pool might respond immediately, so be sure not to depend on a delay!

So to amend the template request we used initially, now we use:
{"id": 0, "method": "getblocktemplate", "params": [{
"capabilities": ["coinbasetxn", "workid", "coinbase/append"],
"longpollid": "some gibberish",
}]}

======Submitting shares======
When miner find the job which meets requested difficulty, it can submit the block to the server as a share:
{"id": 0, "method": "submitblock", "params": [
"020000003c48a294584f90e58325c60ca82896d071826b45680a661cec4d424d00000000
de6433d46c0c7f50d84a05aec77be0199176cdd47f77e344b6f50c84380fddba66dc47501d00ff
ff0000010001010000000100000000000000000000000000000000000000000000000000000000
00000000ffffffff1302955d0f00456c6967697573005047dc66085fffffffff02fff1052a0100
00001976a9144ebeb1cd26d6227635828d60d3e0ed7d0da248fb88ac01000000000000001976a9
147c866aee1fa2f3b3d5effad576df3dbf1f07475588ac00000000"
]}

To assemble the block data, simply concatenate your block header, number of transactions encoded in [[Protocol specification#Variable length integer|Bitcoin varint format]], followed by each of the transactions in your block (beginning with the coinbase).
If the server has listed "submit/coinbase" in its "mutable" key, you may opt to omit the transactions after the coinbase.

Python example:
def varintEncode(n):
if n < 0xfd:
return struct.pack('<B', n)
# NOTE: Technically, there are more encodings for numbers bigger than
# 16-bit, but transaction counts can't be that high with version 2 Bitcoin
# blocks
return b'\xfd' + struct.pack('<H', n)
blkdata = blkheader + varintEncode(len(txnlist)) + coinbase
if 'submit/coinbase' not in template.get('mutable', ()):
for txn in txnlist[1:]:
blkdata += txn

==History==

Getblocktemplate's origins trace back to forrestv's getmemorypool JSON-RPC method for bitcoind.
He created it so that his pool ([[P2Pool]]) could piggy-back on bitcoind so as to avoid harming the Bitcoin network (up to this point, it mined only empty blocks that never confirmed transactions).
Having been fighting with scalability problems in pushpool/bitcoind for months on his pool ([[Eligius]]), Luke-Jr set out to implement a fast pool server using getmemorypool to do its own block production (this became [[Eloipool]], this first open source makes-its-own-blocks poolserver).
Other poolservers also implemented block creation using getmemorypool over the months following.

At about the same time, interest in decentralizing pooled mining became a hot topic.
While [[BitPenny]] had initially released its own decentralized mining proxy months prior, [[P2Pool]]'s implementation became rapidly popular.
Anyone involved in Bitcoin mining protocols could see the need to move control of block creation back into the hands of the miners.
Unfortunately, both [[BitPenny]] and [[P2Pool]] had used very pool-specific proprietary protocols to implement their decentralization.
On the other hand, getmemorypool was *almost* a perfect fit for the task - it just lacked support for the now-ubiquitous pooled mining extensions that had developed around the getwork protocol over time.

In February of 2012, Luke implemented and [https://bitcointalk.org/?topic=23768.msg774497#msg774497 deployed] a first draft of getmemorypool mining support in [[Eloipool]] (and on [[Eligius]]) along with a proof-of-concept getwork proxy (now known as gmp-proxy), adding revisions as needed to function as a general-purpose decentralized mining protocol.
After he had confirmed it was working, he documented and proposed it on the [[Bitcoin development mailing list]] for review on February 28th, where discussion began on what was missing and what needed to be changed or clarified.
During the following few months, a number of others, both developers and testers, provided constructive criticism and suggestions, which were integrated into the standard.
Luke also actively encouraged participation in the development of the standard among pool operators and poolserver authors, especially as it became necessary to move forward into the ASIC "mining generation".
Eventually, it was decided it would be best to rename it to the more appropriate "getblocktemplate" name and drop backward compatibility with getmemorypool for simplicity.
The standard was split into two pieces and the technical specification can be found in [[BIP 0022|BIP 22]] and [[BIP 0023|BIP 23]].

Hi there. For Category:Block_chain_browsers the rationale for adding Blockonomics is that it "now has search and is classified as blockexplorer by many". Perhaps the category itself should be amended, in that case, to include everything that people feel like is something sort of like bc.i? As it is, there's no way to browse (title) or navigate (top sentence) the block chain through Blockonomics.

Address reuse

2015-08-06T13:34:32Z

TheRealSteve: Bitcoin vs bitcoin, see: https://en.bitcoin.it/wiki/Introduction#Capitalization_.2F_Nomenclature (wiki could do with a proper style guide)

'''Address reuse''' refers to the use of the same address for multiple transactions. It is an unintended practice, abusing the privacy and security of the participants of the transactions as well as future holders of their value.

== Problems ==
=== Privacy ===
Address reuse harms the privacy of not only yourself, but also others - including many not related to the transaction.
In some cases, these risks are serious enough that they are likely in violation of reasonable consumer protection laws.

When addresses are re-used, they allow others to much more easily and reliably determine that the address being reused is yours. Every time the re-used address's private key signs a fresh transaction, whoever receives it can use the histories of that address to discover information about you, and everyone who is interested in discovering the identity of the address's owner has one more target they can try to contact to discover who you are.

The relationship graph in a re-used address is powerfully-linked in that '''all''' of the inputs to that address are necessarily joined (via the spending authority of your private key) to all of its outputs.

There has been significant research into the area of what researchers are calling 'identity collapse', which is what happens when more than one Bitcoin address is strongly-linked via the Bitcoin transaction graph to another. Re-using addresses makes their job trivial. There are publically-known databases that exist, right now, that have not only collapsed millions of Bitcoin addresses, but used publically-available information to '''link''' those collapsed identities to individuals, and these databases are being actively maintained.

While you may be okay with some random European researcher bound by his ethics board to conceal your identity from the public at-large, it is very possible that people who accept money from you may not be aware of your decision: thus, via your privacy-decreasing action, people further on the address signing chain could thus be putting '''you''' at risk if they spend their bitcoin on something that catches the attention of law enforcement.

Additionally, in the event that you knowingly make this choice (which you are doing, now that you've read this,) the transaction histories that you are responsible for linking in the event you are a retailer of some sort could put the privacy of your customers at risk because now your well-known singular address(es) which can be strongly linked to your corporate identity can be assumed to be economic activity interacting with your corporate identity.

See also: [http://www.bitcoinnotbombs.com/innovations-that-enhance-bitcoin-anonymity/ Innovations that Enhance Bitcoin Anonymity]

==== Worked Example 1 ====
* You save in bitcoin, using a [[Paper Wallet | single-address paper wallet]].
* All your bitcoin savings to this same address, let's say it contains $1 million worth.
* You buy a small amount of bitcoins to add to your savings, depositing in the paper wallet.
* The person who sold you the bitcoins follows their trail on the blockchain and finds your paper wallet containing $1 million.
* He mentions it to someone in a cafe or bar.
* Word gets around. A burglar raids your home. Kidnappers capture your children and know exactly how much to demand in ransom.

==== Worked Example 2 ====
* You use a single Bitcoin address for all your earning and spending. Anyone you trade with can see a complete history of your finances.
* Your landlord can see your salary, when he raises the rent he knows exactly how much to ask for.
* Your shopkeeper can see your spending. Gossip gets around of how much you spend on pornography and how little on church donations.
* Your employer can see your spending. When you pay labour union dues or donate to wikileaks or another non-profit, your boss knows who not to trust.

=== Security ===
Bitcoin does not, at a low level, have any concept of addresses, only individual coins.
Address reuse, at this layer, requires producing multiple digital signatures when you spend bitcoins.
Multiple situations have been found where more than one digital signature can be used to calculate the private key needed to spend bitcoins.
Even if you spend all the bitcoins claimed by this private key at once, it is still possible to double-spend them in theft before they confirm.
While the known situations for finding the private key from signatures have been fixed, it is not prudent to assume there aren't more such situations yet unknown.

In the case of spending all the TXOs in a single transaction, there is an additional risk if someone is actively monitoring the network for vulnerable transactions.
Upon receiving such a transaction, they can split up their double spends such that there is only one ECDSA verification per transaction (making a single transaction for each TXO).
This will cause the attacker's transactions to relay across the rest of the nodes ''faster'' than the legitimate one, increasing success of a double spend.

==== Known attacks ====

* Same K in multiple signatures, see; [http://www.nilsschneider.net/2013/01/28/recovering-bitcoin-private-keys.html Recovering Bitcoin private keys using weak signatures from the blockchain].
* [https://eprint.iacr.org/2014/140.pdf Timing sidechannel]

=== Accidental loss ===
In Bitcoin abstraction, an address is an invoice for a specific payment.
Once that payment is made, the receiving party has no reason to retain the data for the address (technical details simplified) and may discard it.
Even if someone does not choose to discard that data, it may have since been lost in an accident or compromised.
In any of these situations, any future payments to the same address would go in to a "black hole", and be forever lost through no fault of the recipient.

=== High Fees ===
A single invoice payment using P2PKH can be redeemed and spent with a predictable fee because the transaction should have a predictable size. Software that determines payment and available funds based on "address balance" can cause loss through high fees. If you are paid to an address in many small increments, you will pay a much higher transaction fee when redeeming those payments. It is much more useful for a client to display transaction outputs spendable than address balances for this reason.

== Notable offenders ==
Some notable Bitcoin software and services encourage or require address reuse:
* Many bitcoin mining pools (especially [[Eligius]])
* Electrum displays addresses in a way that encourages confusion and address reuse and misuse.

Changelog

2015-08-02T10:28:14Z

TheRealSteve: +bitcoin.org link - github is currently missing 0.11.0 release notes.

This page aggregates the changelogs that have been posted on the forum for the Bitcoin releases.
Note that some download links are not longer valid as highly insecure versions may have been deleted, or links may have changed.

This page hasn't been updated for a while. Changelogs for newer versions as well as historical release notes can be found at bitcoin.org: https://bitcoin.org/en/version-history and/or through github: https://github.com/bitcoin/bitcoin/tree/master/doc/release-notes

=Changelogs=

https://bitcoin.org/en/release/v0.7.1
==0.7.X==

===0.7.1<ref>[https://bitcoin.org/en/release/v0.7.1 0.7.1 release announcement]</ref>===

New features:

* Added a boolean argument to the RPC stop command, if true sets -detachdb to create standalone database .dat files before shutting down.

* -salvagewallet command-line option, which moves any existing wallet.dat to wallet.{timestamp}.dat and then attempts to salvage public/private keys and master encryption keys (if the wallet is encrypted) into a new wallet.dat. This should only be used if your wallet becomes corrupted, and is not intended to replace regular wallet backups.

* Import $DataDir/bootstrap.dat automatically, if it exists.

==0.6.X==
After 0.6.3, all subsequent releases are stable maintenance releases, 0.7.0 is based on 0.6.3.

===0.6.3<ref>[https://bitcointalk.org/index.php?topic=89877.0 0.6.3 release announcement]</ref>===
Bitcoin version 0.6.3 is now available for download at:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.3/

This is a bug-fix release, with no new features.

Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

CHANGE SUMMARY

Fixed a serious denial-of-service attack that could cause the
bitcoin process to become unresponsive. Thanks to Sergio Lerner
for finding and responsibly reporting the problem. (CVE-2012-3789)

Optimized the process of checking transaction signatures, to
speed up processing of new block messages and make propagating
blocks across the network faster.

Fixed an obscure bug that could cause the bitcoin process to get
stuck on an invalid block-chain, if the invalid chain was
hundreds of blocks long.

Bitcoin-Qt no longer automatically selects the first address
in the address book (Issue #1384).

Fixed minimize-to-dock behavior of Bitcon-Qt on the Mac.

Added a block checkpoint at block 185,333 to speed up initial
blockchain download.

===0.6.2<ref>[https://bitcointalk.org/index.php?topic=80187.0 0.6.2 release announcement]</ref>===
Bitcoin version 0.6.2 is now available for download at:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.2/

This is a bug-fix and code-cleanup release, with no major new features.

Please report bugs using the github issue tracker at:
https://github.com/bitcoin/bitcoin/issues

NOTABLE CHANGES

Much faster shutdowns. However, the blkindex.dat file is no longer
portable to different data directories by default. If you need a
portable blkindex.dat file then run with the new -detachdb=1 option
or the "Detach databases at shutdown" GUI preference.

Fixed https://github.com/bitcoin/bitcoin/issues/1065, a bug that
could cause long-running nodes to crash.

Mac and Windows binaries are compiled against OpenSSL 1.0.1b (Linux
binaries are dynamically linked to the version of OpenSSL on the system).

CHANGE SUMMARY

Use 'git shortlog --no-merges v0.6.0..' for a summary of this release.

Source codebase changes:
- Many source code cleanups and warnings fixes. Close to building with -Wall
- Locking overhaul, and several minor locking fixes
- Several source code portability fixes, e.g. FreeBSD

JSON-RPC interface changes:
- addmultisigaddress enabled for mainnet (previously only enabled for testnet)

Network protocol changes:
- protocol version 60001
- added nonce value to "ping" message (BIP 31)
- added new "pong" message (BIP 31)

Backend storage changes:
- Less redundant database flushing, especially during initial block download
- Shutdown improvements (see above)

Qt user interface:
- minor URI handling improvements
- progressbar improvements
- error handling improvements (show message box rather than console exception,
etc.)
- by popular request, make 4th bar of connection icon green

===0.6.1===
Never released

===0.6.0<ref>[https://bitcointalk.org/index.php?topic=74737.0 0.6.0 release announcement]</ref>===
Bitcoin version 0.6.0 is now available for download at:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.6.0/test/

This release includes more than 20 language localizations.
More translations are welcome; join the
project at Transifex to help:
https://www.transifex.net/projects/p/bitcoin/

Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

Project source code is hosted at github; we are no longer
distributing .tar.gz files here, you can get them
directly from github:
https://github.com/bitcoin/bitcoin/tarball/v0.6.0 # .tar.gz
https://github.com/bitcoin/bitcoin/zipball/v0.6.0 # .zip

For Ubuntu users, there is a ppa maintained by Matt Corallo which
you can add to your system so that it will automatically keep
bitcoin up-to-date. Just type
sudo apt-add-repository ppa:bitcoin/bitcoin
in your terminal, then install the bitcoin-qt package.

KNOWN ISSUES

Shutting down while synchronizing with the network
(downloading the blockchain) can take more than a minute,
because database writes are queued to speed up download
time.

NEW FEATURES SINCE BITCOIN VERSION 0.5

Initial network synchronization should be much faster
(one or two hours on a typical machine instead of ten or more
hours).

Backup Wallet menu option.

Bitcoin-Qt can display and save QR codes for sending
and receiving addresses.

New context menu on addresses to copy/edit/delete them.

New Sign Message dialog that allows you to prove that you
own a bitcoin address by creating a digital
signature.

New wallets created with this version will
use 33-byte 'compressed' public keys instead of
65-byte public keys, resulting in smaller
transactions and less traffic on the bitcoin
network. The shorter keys are already supported
by the network but wallet.dat files containing
short keys are not compatible with earlier
versions of Bitcoin-Qt/bitcoind.

New command-line argument -blocknotify=<command>
that will spawn a shell process to run <command>
when a new block is accepted.

New command-line argument -splash=0 to disable
Bitcoin-Qt's initial splash screen

validateaddress JSON-RPC api command output includes
two new fields for addresses in the wallet:
pubkey : hexadecimal public key
iscompressed : true if pubkey is a short 33-byte key

New JSON-RPC api commands for dumping/importing
private keys from the wallet (dumprivkey, importprivkey).

New JSON-RPC api command for getting information about
blocks (getblock, getblockhash).

New JSON-RPC api command (getmininginfo) for getting
extra information related to mining. The getinfo
JSON-RPC command no longer includes mining-related
information (generate/genproclimit/hashespersec).

NOTABLE CHANGES

BIP30 implemented (security fix for an attack involving
duplicate "coinbase transactions").

The -nolisten, -noupnp and -nodnsseed command-line
options were renamed to -listen, -upnp and -dnsseed,
with a default value of 1. The old names are still
supported for compatibility (so specifying -nolisten
is automatically interpreted as -listen=0; every
boolean argument can now be specified as either
-foo or -nofoo).

The -noirc command-line options was renamed to
-irc, with a default value of 0. Run -irc=1 to
get the old behavior.

Three fill-up-available-memory denial-of-service
attacks were fixed.

NOT YET IMPLEMENTED FEATURES

Support for clicking on bitcoin: URIs and
opening/launching Bitcoin-Qt is available only on Linux,
and only if you configure your desktop to launch
Bitcoin-Qt. All platforms support dragging and dropping
bitcoin: URIs onto the Bitcoin-Qt window to start
payment.

PRELIMINARY SUPPORT FOR MULTISIGNATURE TRANSACTIONS

This release has preliminary support for multisignature
transactions-- transactions that require authorization
from more than one person or device before they
will be accepted by the bitcoin network.

Prior to this release, multisignature transactions
were considered 'non-standard' and were ignored;
with this release multisignature transactions are
considered standard and will start to be relayed
and accepted into blocks.

It is expected that future releases of Bitcoin-Qt
will support the creation of multisignature transactions,
once enough of the network has upgraded so relaying
and validating them is robust.

For this release, creation and testing of multisignature
transactions is limited to the bitcoin test network using
the "addmultisigaddress" JSON-RPC api call.

Short multisignature address support is included in this
release, as specified in BIP 13 and BIP 16.

==0.5.X==
After 0.5.1, all subsequent releases are stable maintenance releases, 0.6.0 is based on 0.5.1.

===0.5.5<ref>[https://bitcointalk.org/index.php?topic=79651 0.4.6/0.5.5 release announcement]</ref>===
bitcoind and Bitcoin-Qt version 0.5.5 are now available for download at:
Windows: installer | zip (sig)
Source: tar.gz
bitcoind and Bitcoin-Qt version 0.6.0.7 are also tagged in git, but it is recommended to upgrade to 0.6.1.

These are bugfix-only releases.

Please report bugs by replying to this forum thread. Note that the 0.4.x wxBitcoin GUI client is no longer maintained nor supported. If someone would like to step up to maintain this, they should contact Luke-Jr.

Bitcoin version 0.5.3 is now available for download at:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.3/

This is a bugfix-only release based on 0.5.1.
It also includes a few protocol updates.

Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

Stable source code is hosted at Gitorious:
http://gitorious.org/bitcoin/bitcoind-stable/archive-tarball/v0.5.3#.tar.gz

PROTOCOL UPDATES

BIP 30: Introduce a new network rule: "a block is not valid if it contains a transaction whose hash already exists in the block chain, unless all that transaction's outputs were already spent before said block" beginning on March 15, 2012, 00:00 UTC.
On testnet, allow mining of min-difficulty blocks if 20 minutes have gone by without mining a regular-difficulty block. This is to make testing Bitcoin easier, and will not affect normal mode.

BUG FIXES

Limit the number of orphan transactions stored in memory, to prevent a potential denial-of-service attack by flooding orphan transactions. Also never store invalid transactions at all.
Fix possible buffer overflow on systems with very long application data paths. This is not exploitable.
Resolved multiple bugs preventing long-term unlocking of encrypted wallets
(issue #922).
Only send local IP in "version" messages if it is globally routable (ie, not private), and try to get such an IP from UPnP if applicable.
Reannounce UPnP port forwards every 20 minutes, to workaround routers expiring old entries, and allow the -upnp option to override any stored setting.
Skip splash screen when -min is used, and fix Minimize to Tray function.
Do not blank "label" in Bitcoin-Qt "Send" tab, if the user has already entered something.
Correct various labels and messages.
Various memory leaks and potential null pointer deferences have been fixed.
Handle invalid Bitcoin URIs using "bitcoin://" instead of "bitcoin:".
Several shutdown issues have been fixed.
Revert to "global progress indication", as starting from zero every time was considered too confusing for many users.
Check that keys stored in the wallet are valid at startup, and if not, report corruption.
Enable accessible widgets on Windows, so that people with screen readers such as NVDA can make sense of it.
Various build fixes.
If no password is specified to bitcoind, recommend a secure password.
Automatically focus and scroll to new "Send coins" entries in Bitcoin-Qt.
Show a message box for --help on Windows, for Bitcoin-Qt.
Add missing "About Qt" menu option to show built-in Qt About dialog.
Don't show "-daemon" as an option for Bitcoin-Qt, since it isn't available.
Update hard-coded fallback seed nodes, choosing recent ones with long uptime and versions at least 0.4.0.
Add checkpoint at block 168,000.

No longer accept inbound connections over the internet when Bitcoin is being used with Tor (identity leak).
Re-enable SSL support for the JSON-RPC interface (it was unintentionally disabled for the 0.5.0 and 0.5.1 release Linux binaries).
Use the correct base transaction fee of 0.0005 BTC for accepting transactions into mined blocks (since 0.4.0, it was incorrectly accepting 0.0001 BTC which was only meant to be relayed).
Don't show "IP" for transactions which are not necessarily IP transactions.
Add new DNS seeds (maintained by Pieter Wuille and Luke Dashjr).

MAJOR BUG FIX (CVE-2011-4447)

The wallet encryption feature introduced in Bitcoin version 0.4.0 did not sufficiently secure the private keys. An attacker who
managed to get a copy of your encrypted wallet.dat file might be able to recover some or all of the unencrypted keys and steal the
associated coins.

If you have a previously encrypted wallet.dat, the first time you run bitcoin-qt or bitcoind the wallet will be rewritten, Bitcoin will
shut down, and you will be prompted to restart it to run with the new, properly encrypted file.

If you had a previously encrypted wallet.dat that might have been copied or stolen (for example, you backed it up to a public
location) you should send all of your bitcoins to yourself using a new bitcoin address and stop using any previously generated addresses.

Wallets encrypted with this version of Bitcoin are written properly.

Technical note: the encrypted wallet's 'keypool' will be regenerated the first time you request a new bitcoin address; to be certain that the
new private keys are properly backed up you should:

1. Run Bitcoin and let it rewrite the wallet.dat file

2. Run it again, then ask it for a new bitcoin address.
Bitcoin-Qt: Address Book, then New Address...
bitcoind: run the 'walletpassphrase' RPC command to unlock the wallet, then run the 'getnewaddress' RPC command.

3. If your encrypted wallet.dat may have been copied or stolen, send all of your bitcoins to the new bitcoin address.

4. Shut down Bitcoin, then backup the wallet.dat file.
IMPORTANT: be sure to request a new bitcoin address before backing up, so that the 'keypool' is regenerated and backed up.

"Security in depth" is always a good idea, so choosing a secure location for the backup and/or encrypting the backup before uploading it is recommended. And as in previous releases, if your machine is infected by malware there are several ways an attacker might steal your bitcoins.

Thanks to Alan Reiner (etotheipi) for finding and reporting this bug.

MAJOR GUI CHANGES

"Splash" graphics at startup that show address/wallet/blockchain loading progress.

"Synchronizing with network" progress bar to show block-chain download progress.

Icons at the bottom of the window that show how well connected you are to the network, with tooltips to display details.

Drag and drop support for bitcoin: URIs on web pages.

Export transactions as a .csv file.

Many other GUI improvements, large and small.

RPC CHANGES

getmemorypool : new RPC command, provides everything needed to construct a block with a custom generation transaction and submit a solution

listsinceblock : new RPC command, list transactions since given block

signmessage/verifymessage : new RPC commands to sign a message with one of your private keys or verify that a message signed by the private key associated with a bitcoin address.

GENERAL CHANGES

Faster initial block download.

associated coins.

If you have a previously encrypted wallet.dat, the first time you run wxbitcoin or bitcoind the wallet will be rewritten, Bitcoin will

Wallets encrypted with this version of Bitcoin are written properly.

Technical note: the encrypted wallet's 'keypool' will be regenerated the first time you request a new bitcoin address; to be certain that the
new private keys are properly backed up you should:

1. Run Bitcoin and let it rewrite the wallet.dat file

2. Run it again, then ask it for a new bitcoin address.
wxBitcoin: new address visible on main window
bitcoind: run the 'walletpassphrase' RPC command to unlock the wallet, then run the 'getnewaddress' RPC command.

3. If your encrypted wallet.dat may have been copied or stolen, send all of your bitcoins to the new bitcoin address.

4. Shut down Bitcoin, then backup the wallet.dat file.
IMPORTANT: be sure to request a new bitcoin address before backing up, so that the 'keypool' is regenerated and backed up.

Thanks to Alan Reiner (etotheipi) for finding and reporting this bug.

===0.4.0<ref>[https://bitcointalk.org/index.php?topic=45410.0 0.4 release announcement]</ref>===
Bitcoin version 0.4.0 is now available for download at:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.4.0/

The main feature in this release is wallet private key encryption;
you can set a passphrase that must be entered before sending coins.
See below for more information; if you decide to encrypt your wallet,
WRITE DOWN YOUR PASSPHRASE AND PUT IT IN A SECURE LOCATION. If you
forget or lose your wallet passphrase, you lose your bitcoins.
Previous versions of bitcoin are unable to read encrypted wallets,
and will crash on startup if the wallet is encrypted.

Also note: bitcoin version 0.4 uses a newer version of Berkeley DB
(bdb version 4.8) than previous versions (bdb 4.7). If you upgrade
to version 0.4 and then revert back to an earlier version of bitcoin
the it may be unable to start because bdb 4.7 cannot read bdb 4.8
"log" files.

Notable bug fixes from version 0.3.24:

Fix several bitcoin-becomes-unresponsive bugs due to multithreading
deadlocks.

Optimize database writes for large (lots of inputs) transactions
(fixes a potential denial-of-service attack)

Wallet Encryption

Bitcoin supports native wallet encryption so that people who steal your
wallet file don't automatically get access to all of your Bitcoins.
In order to enable this feature, choose "Encrypt Wallet" from the
Options menu. You will be prompted to enter a passphrase, which
will be used as the key to encrypt your wallet and will be needed
every time you wish to send Bitcoins. If you lose this passphrase,
you will lose access to spend all of the bitcoins in your wallet,
no one, not even the Bitcoin developers can recover your Bitcoins.
This means you are responsible for your own security, store your
passphrase in a secure location and do not forget it.

Remember that the encryption built into bitcoin only encrypts the
actual keys which are required to send your bitcoins, not the full
wallet. This means that someone who steals your wallet file will
be able to see all the addresses which belong to you, as well as the
relevant transactions, you are only protected from someone spending
your coins.

It is recommended that you backup your wallet file before you
encrypt your wallet. To do this, close the Bitcoin client and
copy the wallet.dat file from ~/.bitcoin/ on Linux, /Users/(user
name)/Application Support/Bitcoin/ on Mac OSX, and %APPDATA%/Bitcoin/
on Windows (that is /Users/(user name)/AppData/Roaming/Bitcoin on
Windows Vista and 7 and /Documents and Settings/(user name)/Application
Data/Bitcoin on Windows XP). Once you have copied that file to a
safe location, reopen the Bitcoin client and Encrypt your wallet.
If everything goes fine, delete the backup and enjoy your encrypted
wallet. Note that once you encrypt your wallet, you will never be
able to go back to a version of the Bitcoin client older than 0.4.

Keep in mind that you are always responsible for your own security.
All it takes is a slightly more advanced wallet-stealing trojan which
installs a keylogger to steal your wallet passphrase as you enter it
in addition to your wallet file and you have lost all your Bitcoins.
Wallet encryption cannot keep you safe if you do not practice
good security, such as running up-to-date antivirus software, only
entering your wallet passphrase in the Bitcoin client and using the
same passphrase only as your wallet passphrase.

See the doc/README file in the bitcoin source for technical details
of wallet encryption.

==0.3.X==

===0.3.24<ref>[https://bitcointalk.org/index.php?topic=27187.0 0.3.24 release announcement]</ref>===
Bitcoin v0.3.24 is now available for download at
https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.24/

This is another bug fix release. We had hoped to have wallet encryption ready for release, but more urgent fixes for existing clients were needed -- most notably block download problems were getting severe. Wallet encryption is ready for testing at https://github.com/bitcoin/bitcoin/pull/352 for the git-savvy, and hopefully will follow shortly in the next release, v0.4.

Notable fixes in v0.3.24, and the main reasons for this release:

F1) Block downloads were failing or taking unreasonable amounts of time to complete, because the increased size of the block chain was bumping up against some earlier buffer-size DoS limits.

F2) Fix crash caused by loss/lack of network connection.

Notable changes in v0.3.24:

C1) DNS seeding enabled by default.

C2) UPNP enabled by default in the GUI client. The percentage of bitcoin clients that accept incoming connections is quite small, and that is a problem. This should help. bitcoind, and unofficial builds, are unchanged (though we encourage use of "-upnp" to help the network!)

C3) Initial unit testing framework. Bitcoin sorely needs automated tests, and this is a beginning. Contributions welcome.

C4) Internal wallet code cleanup. While invisible to an end user, this change provides the basis for v0.4's wallet encryption.

===0.3.23<ref>[https://bitcointalk.org/index.php?topic=16553.0 0.3.23 release announcement]</ref>===
Win32, Linux, MacOSX and source releases for bitcoin v0.3.23 have been uploaded to
https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.23/

This is another quick bugfix release, trying to deal with the influx of new bitcoin users.

Main items of note:

* P2P connect-to-node logic changed to reduce timeout a bit. The network saw a huge influx of new users, who do not permit incoming connections. This change is a short-term hack, to more quickly hunt for useful P2P connections. Better "leaf node" logic is in the works, but this should let us limp along until then. One may use -upnp to properly forward ports, and help the network.
* Transaction fee reduced to 0.0005 for new transactions
* Client will relay transactions with fees as low as 0.0001 BTC

===0.3.22<ref>[https://bitcointalk.org/index.php?topic=12269.0 0.3.22 release announcement]</ref>===
Download URL: https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.22/

This is largely a bugfix and TX fee schedule release. We also hope to make 0.3.23 a quick release, to fix problems that the network has seen due to explosive growth in the past week.

Notable changes:
* Client will accept and relay TX's with 0.0005 BTC fee schedule (users still pay 0.01 BTC per kb, until next version)
* Non-standard transactions accepted on testnet
* Source code tree reorganized (prep for autotools build)
* Remove "Generate Coins" option from GUI, and remove 4way SSE miner. Internal reference CPU miner remains available, but users are directed to external miners for best hash production.
* IRC is overflowing. Client now bootstraps to channels #bitcoin00 - #bitcoin99
* DNS names now may be used with -addnode, -connect (requires -dns to enable)

RPC changes:
* 'listtransactions' adds 'from' param, for range queries
* 'move' may take account balances negative
* 'settxfee' added, to manually set TX fee

===0.3.21<ref>[https://bitcointalk.org/index.php?topic=6642.0 0.3.21 release announcement]</ref>===
Binaries for Bitcoin version 0.3.21 are available at:
https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.21/

Changes and new features from the 0.3.20 release include:

* Universal Plug and Play support. Enable automatic opening of a port for incoming connections by running bitcoin or bitcoind with the - -upnp=1 command line switch or using the Options dialog box.

* Support for full-precision bitcoin amounts. You can now send, and bitcoin will display, bitcoin amounts smaller than 0.01. However, sending fewer than 0.01 bitcoins still requires a 0.01 bitcoin fee (so you can send 1.0001 bitcoins without a fee, but you will be asked to pay a fee if you try to send 0.0001).

* A new method of finding bitcoin nodes to connect with, via DNS A records. Use the -dnsseed option to enable.

For developers, changes to bitcoin's remote-procedure-call API:

* New rpc command "sendmany" to send bitcoins to more than one address in a single transaction.

* Several bug fixes, including a serious intermittent bug that would sometimes cause bitcoind to stop accepting rpc requests.

* -logtimestamps option, to add a timestamp to each line in debug.log.

* Immature blocks (newly generated, under 120 confirmations) are now shown in listtransactions.

===0.3.20.2<ref>[https://bitcointalk.org/index.php?topic=4167.0 0.3.20.2 release announcement]</ref>===
The maxsendbuffer bug (0.3.20.1 clients not being able to download the block chain from other 0.3.20.1 clients) was only going to get
worse as people upgraded, so I cherry-picked the bug fix and created a minor release yesterday.

The Amazon Machine Images I used to do the builds are available:

ami-38a05251 Bitcoin-v0.3.20.2 Mingw (Windows; Administrator password 'bitcoin development')
ami-30a05259 Bitcoin_0.3.20.2 Linux32
ami-8abc4ee3 Bitcoin_0.3.20.2 Linux64

(mac build will be done soon)

If you have already downloaded version 0.3.20.1, please either add this to your bitcoin.conf file:

maxsendbuffer=10000
maxreceivebuffer=10000

... or download the new version.

===0.3.20.1===
(No known forum post.)

===0.3.20<ref>[https://bitcointalk.org/index.php?topic=2953.0 0.3.20 release announcement]</ref>===
Please checkout the git integration branch from:

https://github.com/bitcoin/bitcoin

... and help test. The new features that need testing are:

* -nolisten : https://github.com/bitcoin/bitcoin/pull/11
* -rescan : scan block chain for missing wallet transactions
* -printtoconsole : https://github.com/bitcoin/bitcoin/pull/37
* RPC gettransaction details : https://github.com/bitcoin/bitcoin/pull/24
* listtransactions new features : https://github.com/bitcoin/bitcoin/pull/10

Bug fixes that also need testing:

* -maxconnections= : https://github.com/bitcoin/bitcoin/pull/42
* RPC listaccounts minconf : https://github.com/bitcoin/bitcoin/pull/27
* RPC move, add time to output : https://github.com/bitcoin/bitcoin/pull/21
* ...and several improvements to --help output.

This needs more testing on Windows! Please drop me a quick private message, email, or IRC message if you are able to do some testing. If you find bugs, please open an issue at:

===0.3.19<ref>[https://bitcointalk.org/index.php?topic=2228.0 0.3.19 release announcement]</ref>===
There's more work to do on DoS, but I'm doing a quick build of what I have so far in case it's needed, before venturing into more complex ideas. The build for this is version 0.3.19.

- Added some DoS controls
As Gavin and I have said clearly before, the software is not at all resistant to DoS attack. This is one improvement, but there are still more ways to attack than I can count.

I'm leaving the -limitfreerelay part as a switch for now and it's there if you need it.

- Removed "safe mode" alerts
"safe mode" alerts was a temporary measure after the 0.3.9 overflow bug. We can say all we want that users can just run with "-disablesafemode", but it's better just not to have it for the sake of appearances. It was never intended as a long term feature. Safe mode can still be triggered by seeing a longer (greater total PoW) invalid block chain.

===0.3.18<ref>[https://bitcointalk.org/index.php?topic=2162.0 0.3.18 release announcement]</ref>===

Changes:
* Fixed a wallet.dat compatibility problem if you downgraded from 0.3.17 and then upgraded again
* IsStandard() check to only include known transaction types in blocks
* Jgarzik's optimisation to speed up the initial block download a little

The main addition in this release is the Accounts-Based JSON-RPC commands that Gavin's been working on (more details at http://www.bitcoin.org/smf/index.php?topic=1886.0).
* getaccountaddress
* sendfrom
* move
* getbalance
* listtransactions

===0.3.17<ref>[https://bitcointalk.org/index.php?topic=1946.0 0.3.17 release announcement]</ref>===

Version 0.3.17 is now available.

Changes:
* new getwork, thanks m0mchil
* added transaction fee setting in UI options menu
* free transaction limits
* sendtoaddress returns transaction id instead of "sent"
* getaccountaddress <account>

The UI transaction fee setting was easy since it was still there from 0.1.5 and all I had to do was re-enable it.

The accounts-based commands: move, sendfrom and getbalance <account> will be in the next release. We still have some more changes to make first.

===0.3.16===

Never released.

===0.3.15<ref>[https://bitcointalk.org/index.php?topic=1780.0 0.3.15 release announcement]</ref>===

* paytxfee switch is now per KB, so it adds the correct fee for large transactions
* sending avoids using coins with less than 6 confirmations if it can
* BitcoinMiner processes transactions in priority order based on age of dependencies
* make sure generation doesn't start before block 74000 downloaded
* bugfixes by Dean Gores
* testnet, keypoololdest and paytxfee added to getinfo

===0.3.14<ref>[https://bitcointalk.org/index.php?topic=1528.0 0.3.14 release announcement]</ref>===

Version 0.3.14 is now available
http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.14/

Changes:
* Key pool feature for safer wallet backup
Gavin Andresen:
* TEST network mode with switch -testnet
* Option to use SSL for JSON-RPC connections on unix/osx
* validateaddress RPC command
eurekafag:
* Russian translation

===0.3.13<ref>[https://bitcointalk.org/index.php?topic=1327.0 0.3.13 release announcement]</ref>===

Version 0.3.13 is now available. You should upgrade to prevent potential problems with 0/unconfirmed transactions. Note: 0.3.13 prevents problems if you haven't already spent a 0/unconfirmed transaction, but if that already happened, you need 0.3.13.2.

Changes:
* Don't count or spend payments until they have 1 confirmation.
* Internal version number from 312 to 31300.
* Only accept transactions sent by IP address if -allowreceivebyip is specified.
* Dropped DB_PRIVATE Berkeley DB flag.
* Fix problem sending the last cent with sub-cent fractional change.
* Auto-detect whether to use 128-bit 4-way SSE2 on Linux.
Gavin Andresen:
* Option -rpcallowip= to accept json-rpc connections from another machine.
* Clean shutdown on SIGTERM on Linux.

(Thanks Laszlo for the Mac OSX build!)

Note:
The SSE2 auto-detect in the Linux 64-bit version doesn't work with AMD in 64-bit mode. Please try this instead and let me know if it gets it right:
http://www.bitcoin.org/download/bitcoin-0.3.13.1-specialbuild-linux64.tar.gz

You can still control the SSE2 use manually with -4way and -4way=0.

Version 0.3.13.2 (SVN rev 161) has improvements for the case where you already had 0/unconfirmed transactions that you might have already spent. Here's a Windows build of it:
http://www.bitcoin.org/download/bitcoin-0.3.13.2-win32-setup.exe

===0.3.12<ref>[https://bitcointalk.org/index.php?topic=999.0 0.3.12 release announcement]</ref>===

Version 0.3.12 is now available.

Features:
* json-rpc errors return a more standard error object. (thanks to Gavin Andresen)
* json-rpc command line returns exit codes.
* json-rpc "backupwallet" command.
* Recovers and continues if an exception is caused by a message you received. Other nodes shouldn't be able to cause an exception, and it hasn't happened before, but if a way is found to cause an exception, this would keep it from being used to stop network nodes.

If you have json-rpc code that checks the contents of the error string, you need to change it to expect error objects of the form {"code":<number>,"message":<string>}, which is the standard. See this thread:

Bitcoin Improvement Proposals

2015-07-31T23:14:02Z

TheRealSteve: /* List of BIPs */ +BIP 101 - see Talk page - does 100+ need a group comment, too?

A '''Bitcoin Improvement Proposal''' ('''BIP''') is a design document for introducing features or information to Bitcoin. This is the standard way of communicating ideas since Bitcoin has no formal structure.

The first BIP ([[BIP 0001]]) was submitted by Amir Taaki on 2011-08-19 and described what a BIP is.

= BIP Types =
There are three types of BIPs:
* '''Standards Track BIPs''' - Changes to the network protocol, block or transaction validation, or anything affecting interoperability.
* '''Informational BIPs''' - Design issues, general guidelines. This type of BIP is NOT for proposing new features and do not represent community consensus
* '''Process BIPs''' - Describes or proposes a change in process. Similar to Standards BIPs but apply outside the Bitcoin protocol.

= BIP Workflow =
As described in [[BIP 0001]] the workflow of a BIP is as follows:

[[File:BIP Workflow.png]]

= List of BIPs =
{{BipMoved|README.mediawiki|README}}

People wishing to submit BIPs, first should propose their idea or document to [http://sourceforge.net/p/bitcoin/mailman/bitcoin-development/ the mailing list]. After discussion they should email Greg Maxwell <gmaxwell@gmail.com>. After copy-editing and acceptance, it will be published here.

We are fairly liberal with approving BIPs, and try not to be too involved in decision making on behalf of the community. The exception is in very rare cases of dispute resolution when a decision is contentious and cannot be agreed upon. In those cases, the conservative option will always be preferred.

Having a BIP here does not make it a formally accepted standard until its status becomes Active. For a BIP to become Active requires the mutual consent of the community.

Those proposing changes should consider that ultimately consent may rest with the consensus of the Bitcoin users (see also: [[economic majority]]).

Controlled supply

2015-07-30T22:13:52Z

TheRealSteve: /* Projected Bitcoins Long Term */ Removed the years - see discussion page for details - and right-aligned the contents.

<blockquote>A fixed money supply, or a supply altered only in accord with objective and calculable criteria, is a necessary condition to a meaningful just price of money.<ref>[https://www.scribd.com/doc/138347161/Bernard-W-Dempsey-1903-1960-Interest-and-Usury-With-an-Introduction-by-Joseph-a-Schumpeter-1948#page220 <i>Interest and Usury</i> p. 220] by [https://www.jstor.org/stable/29769582 Fr. Bernard W. Dempsey, S.J.] (1903-1960); cf. John Horvat II [http://returntoorder.org/ <i>Return to Order</i>] ch. 37 "The Backing of Money"</ref>
<p align="right">—[https://www.jstor.org/stable/29769582 Fr. Bernard W. Dempsey, S.J.] (1903-1960)</p></blockquote>

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The
[[wikipedia:monetary base|monetary base]] is controlled by a central bank. In the United States, the [[wikipedia:Federal Reserve System|Fed]] increases the monetary base by issuing currency, increasing the amount banks have on reserve, and more recently, printing money electronically in a process called [[wikipedia:Quantitative Easing|Quantitative Easing]].

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

==Currency with Finite Supply==
[[Image:Controlled supply-block reward halving.png|160px|thumb|right| Block reward halving]]
[[Image:Controlled supply-supply over block height.png|160px|thumb|right| Controlled supply]]
Bitcoins are created each time a user discovers a new [[block]].
The rate of block creation is approximately constant over time: 6 per hour. The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of bitcoins in existence will never exceed 21 million.<ref>[http://www.bitcointalk.org/index.php?topic=3366.msg47522#msg47522 21 million cap]</ref> Speculated justifications for the unintuitive value "21 million" are: it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number.

[[File:ControlledSupply.gif]]

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called [[Mining|''Miners'']].

==Projected Bitcoins Short Term ==
This chart shows the number of bitcoins that will exist in the near future. The ''Year'' is a forecast and may be slightly off.

==Projected Bitcoins Long Term ==
[[Image:Controlled supply-timeline estimation.png|160px|thumb|right| Supply timeline estimation]]
Because the number of bitcoins created each time a user discovers a new block - the block reward - is halved based on a fixed interval of blocks, and the time it takes on average to discover a block can vary based on [[mining]] power and the network [[difficulty]], the exact time when the block reward is halved can vary as well. Consequently, the time the last Bitcoin will be created will also vary, and is subject to speculation based on assumptions.

If the mining power had remained constant since the first Bitcoin was mined, the last Bitcoin would have been mined on October 8th, 2140. Due to the mining power having increased overall over time, as of block 367,500 - assuming mining power remains constant from that block forward - the last Bitcoin would be mined on May 7th, 2140.

As it is very difficulty to predict how mining power will evolve going into the future - i.e. whether technological progress will continue to make hardware faster or whether mining will hit a a technological wall, or whether or not faster methods of calculation will be discovered - putting an exact date or even year on this event is difficult as well.

The total number of bitcoins, as mentioned earlier, will tend toward 21 million. Due to a technical limitation in the data structure of the blockchain - specifically of the [[Transaction#general_format_.28inside_a_block.29_of_each_output_of_a_transaction_-_Txout|transaction output]], this exact value is 20,999,999.9769 bitcoin. Should this technical limitation is adjusted, the total number will still only be a maximum of 21 million.

''Note: The number of bitcoins are presented in a floating point format. However, these values are based on the number of satoshi per block originally in integer format to prevent compounding error.''

==Spendable Supply==
The theoretical total number of bitcoins, 21 million, should not be confused with the total spendable supply. The total spendable supply is always lower than the theoretical total supply, and is subject to accidental loss, willful destruction, and technical peculiarities.

===Loss of bitcoin===
Bitcoins may be lost if the conditions required to spend them are no longer known. For example, if you made a transaction to an [[address]] that requires a private key in order to spend those bitcoins further, had written that private key down on a piece of paper, but that piece of paper was lost. In this case, that bitcoin may also be considered lost, as the odds of randomly finding a matching private key are such that it is generally considered impossible.

===Willful destruction of bitcoin===
Bitcoins may also be willfully 'destroyed' - for example by attaching conditions that make it impossible to spend them.

A common method is to send bitcoin to an address that was constructed and only made to pass validity checks, but for which no private key is actually known. An example of such an address is "1BitcoinEaterAddressDontSendf59kuE", where the last "f59kuE" is text to make the preceding constructed text pass validation. Finding a matching private key is, again, generally considered impossible. For an example of how difficult this would be, see [[Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses|Vanitygen]].

Another common method is to send bitcoin in a transaction where the conditions for spending are not just unfathomably unlikely, but literally impossible to meet. For example, a transaction that is made [[Script#Provably_Unspendable.2FPrunable_Outputs|provably unspendable using OP_RETURN]], or uses script operations that requires the user to prove that 1+1 equals 3.

A lesser known method is to send bitcoin to an address based on private key that is outside the [[Private_key#Range_of_valid_ECDSA_private_keys|range of valid ECDSA private keys]]. For example, the address 16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM has a known matching private key of value 0 (zero), which is outside the valid range.

===Technical peculiarities preventing spending of bitcoin===
There are also technical peculiarities that prevent the spending of some bitcoin.

The first {{btc}}50, included in the [[genesis block]], cannot be spent as its transaction is not in the global database.

In older versions of the bitcoin reference code, a miner could make their coinbase transaction (block reward) have the exact same ID as used in a previous block<ref>https://github.com/bitcoin/bitcoin/issues/612</ref>. This effectively caused the previous block reward to become unspendable. Two known such cases<ref>{{cite tx|e3bf3d07d4b0375638d5f1db5255fe07ba2c4cb067cd81b84ee974b6585fb468|used in blocks 91722 and 91880}}</ref><ref>{{cite tx|d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599|used in blocks 91812 and 91842</ref> are left as special cases in the code<ref>https://github.com/bitcoin/bitcoin/commit/ab91bf39b7c11e9c86bb2043c24f0f377f1cf514</ref> as part of [[BIP 0030]] changes that fixed this issue. These transactions were {{btc}}50 each.

==Money Supply==
While the number of bitcoins in existence will never exceed 21 million, the [[wikipedia:money supply|money supply]] of bitcoins can exceed 21 million due to [[wikipedia:Fractional-reserve Banking|Fractional-reserve Banking]].

==Deflation==

Because the monetary base of bitcoins cannot be expanded, the currency would be subject to severe deflation if it becomes widely used.
Keynesian economists argue that [[Deflationary spiral|deflation]] is bad for an economy because it incentivises individuals and businesses to save money rather than invest in businesses and create jobs. The [[wikipedia:Austrian school|Austrian school]] of thought counters this criticism, claiming that as deflation occurs in all stages of production, entrepreneurs who invest benefit from it. As a result, profit ratios tend to stay the same and only their magnitudes change. In other words, in a deflationary environment, goods and services decrease in price, but at the same time the cost for the production of these goods and services tend to decrease proportionally, effectively not affecting profits. Price deflation encourages an increase in hoarding — hence savings — which in turn tends to lower interest rates and increase the incentive for entrepreneurs to invest in projects of longer term.

== Do not Resurrect That Stupid Graph ==
Please see my points over at [[File_talk:Total_bitcoins_over_time_graph.png]] which describe why I deleted the graph, and description of a suitable alternative. Seriously, the amount of misleading information that prior graph has disseminated into the public is horrorshow-enormous. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 07:11, 14 September 2014 (UTC)

== Actual Supply is Different From The Tables Here ==
Note that the actual supply is different than what is listed on these graphs due to provably destroyed coins, duplicate coinbase, and underpays; this should be accounted-for in the graphs. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 16:32, 16 September 2014 (UTC)
:I'm not sure if 'destroyed' coins should be taken into account. While they may never become part of transactions again, they were at least created. Duplicate coinbase and underpays are a different matter. I'd like to take these into account in at least the description in one of my graphs (see the talk page for the deleted graph), but would also like to see some source material from which to glean actual numbers. If you, or anybody else, can help out with this, it would be appreciated. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 21:48, 12 April 2015 (UTC)
:I'd still like to see some examples of further technical peculiarities that make existing bitcoin unspendable, as well as examples of bitcoin that actually entered into existence when it shouldn't have (thus raising the maximum), didn't enter into existence when they should have (thus lowering the maximum) and any other case that isn't simple loss or willful destruction. There's a section on this now, so by all means, add there directly [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 12:36, 20 July 2015 (UTC)

== Projected Bitcoins (Long Term) - the numbers ==

The Projected Bitcoins Long Term table in the page uses [[Units|Bitcoin]] unit representation as a floating point number with an 8-digit precision to convey the actual number in [[Satoshi (unit)|satoshi]], which has an integer representation inside the [[Bitcoin Core|satoshi client]].

Each of the values is based on the actual number of satoshi rewarded per block. This reward halves every 210,000 blocks.[https://github.com/bitcoin/bitcoin/blob/master/src/main.cpp#L1179] This halving presents a potential point of confusion; at some point the reward would be 610,351.5 satoshi - which at {{as of|2015|04|04}} cannot exist in the satoshi client's fixed point arithmetic limit.<br />
The value is, instead, truncated to 610,351 satoshi. The total number of satoshi generated during that reward era is thus not <tt>210,000 * 610,351.5 = 128,173,815,000 (<span class="btc">BTC</span>1,281.73815000)</tt>, but <tt>210,000 * 610,351 = 128,173,710,000 (<span class="btc">BTC</span>1,281.73710000)</tt>. The same problem presents itself with any subsequent reward eras .<br />
An earlier version of the table in this page had a single satoshi error in some of the values, likely due to related floating point accuracy issues.[http://www.reddit.com/r/Bitcoin/comments/31g89l/rounding_error_in_the_wiki/]

At the actual last round there should be a total of <tt><span class="btc">BTC</span>20,999,999.97690000</tt>.<br />
If using floating point math throughout, depending on the accuracy and behavior of the floating point calculations, this could end up being calculated as <tt><span class="btc">BTC</span>20999999.99877760</tt>, or a difference of <tt><span class="btc">BTC</span>0.02187764</tt>.<br />
The floating point math approach will tend toward a total supply of <tt><span class="btc">BTC</span>21,000,000</tt>, and a difference from the actual current maximum of <tt><span class="btc">BTC</span>0.0231</tt>.

For technical purposes, the total supply should be noted as <tt><span class="btc">BTC</span>20,999,999.97690</tt> with a reminder that this depends on the current fixed point arithmetic. For colloquial use, <tt><span class="btc">BTC</span>21,000,000</tt> should be acceptable. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 22:01, 4 April 2015 (UTC)

== Projected Bitcoins (Long Term) 'Years' column removal ==

I've finally removed the Years column from the "Projected Bitcoins Long Term" table. There's multiple arguments in favor of this: 1. The existing format was decimal years, which aren't very layperson friendly. 2. Laypersons may be misled to believe these year/date values are set in stone, when they are not. For relevant discussion, see the arguments regarding an earlier graph which I can only presume (as the file was deleted) was equally misleading, and this reddit comment thread (disclaimer: I'm a participant in that thread): https://www.reddit.com/r/Bitcoin/comments/31g89l/rounding_error_in_the_wiki/ . If anybody wants to put year/date numbers back in: it's a wiki, go ahead, but I'd appreciate an outline of the arguments in favor in response here :) [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 22:11, 30 July 2015 (UTC)

Controlled supply

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The
[[wikipedia:monetary base|monetary base]] is controlled by a central bank. In the United States, the [[wikipedia:Federal Reserve System|Fed]] increases the monetary base by issuing currency, increasing the amount banks have on reserve, and more recently, printing money electronically in a process called [[wikipedia:Quantitative Easing|Quantitative Easing]].

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

==Currency with Finite Supply==
[[Image:Controlled supply-block reward halving.png|160px|thumb|right| Block reward halving]]
[[Image:Controlled supply-supply over block height.png|160px|thumb|right| Controlled supply]]
Bitcoins are created each time a user discovers a new [[block]].
The rate of block creation is approximately constant over time: 6 per hour. The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of bitcoins in existence will never exceed 21 million.<ref>[http://www.bitcointalk.org/index.php?topic=3366.msg47522#msg47522 21 million cap]</ref> Speculated justifications for the unintuitive value "21 million" are: it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number.

[[File:ControlledSupply.gif]]

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called [[Mining|''Miners'']].

==Projected Bitcoins Short Term ==
This chart shows the number of bitcoins that will exist in the near future. The ''Year'' is a forecast and may be slightly off.

==Projected Bitcoins Long Term ==
[[Image:Controlled supply-timeline estimation.png|160px|thumb|right| Supply timeline estimation]]
Because the number of bitcoins created each time a user discovers a new block - the block reward - is halved based on a fixed interval of blocks, and the time it takes on average to discover a block can vary based on [[mining]] power and the network [[difficulty]], the exact time when the block reward is halved can vary as well. Consequently, the time the last Bitcoin will be created will also vary, and is subject to speculation based on assumptions.

If the mining power had remained constant since the first Bitcoin was mined, the last Bitcoin would have been mined on October 8th, 2140. Due to the mining power having increased overall over time, as of block 367,500 - assuming mining power remains constant from that block forward - the last Bitcoin would be mined on May 7th, 2140.

As it is very difficulty to predict how mining power will evolve going into the future - i.e. whether technological progress will continue to make hardware faster or whether mining will hit a a technological wall, or whether or not faster methods of calculation will be discovered - putting an exact date or even year on this event is difficult as well.

The total number of bitcoins, as mentioned earlier, will tend toward 21 million. Due to a technical limitation in the data structure of the blockchain - specifically of the [[Transaction#general_format_.28inside_a_block.29_of_each_output_of_a_transaction_-_Txout|transaction output]], this exact value is 20,999,999.9769 bitcoin. Should this technical limitation is adjusted, the total number will still only be a maximum of 21 million.

''Note: The number of bitcoins are presented in a floating point format. However, these values are based on the number of satoshi per block originally in integer format to prevent compounding error.''

==Spendable Supply==
The theoretical total number of bitcoins, 21 million, should not be confused with the total spendable supply. The total spendable supply is always lower than the theoretical total supply, and is subject to accidental loss, willful destruction, and technical peculiarities.

===Loss of bitcoin===
Bitcoins may be lost if the conditions required to spend them are no longer known. For example, if you made a transaction to an [[address]] that requires a private key in order to spend those bitcoins further, had written that private key down on a piece of paper, but that piece of paper was lost. In this case, that bitcoin may also be considered lost, as the odds of randomly finding a matching private key are such that it is generally considered impossible.

===Willful destruction of bitcoin===
Bitcoins may also be willfully 'destroyed' - for example by attaching conditions that make it impossible to spend them.

A common method is to send bitcoin to an address that was constructed and only made to pass validity checks, but for which no private key is actually known. An example of such an address is "1BitcoinEaterAddressDontSendf59kuE", where the last "f59kuE" is text to make the preceding constructed text pass validation. Finding a matching private key is, again, generally considered impossible. For an example of how difficult this would be, see [[Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses|Vanitygen]].

Another common method is to send bitcoin in a transaction where the conditions for spending are not just unfathomably unlikely, but literally impossible to meet. For example, a transaction that is made [[Script#Provably_Unspendable.2FPrunable_Outputs|provably unspendable using OP_RETURN]], or uses script operations that requires the user to prove that 1+1 equals 3.

A lesser known method is to send bitcoin to an address based on private key that is outside the [[Private_key#Range_of_valid_ECDSA_private_keys|range of valid ECDSA private keys]]. For example, the address 16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM has a known matching private key of value 0 (zero), which is outside the valid range.

===Technical peculiarities preventing spending of bitcoin===
There are also technical peculiarities that prevent the spending of some bitcoin.

The first {{btc}}50, included in the [[genesis block]], cannot be spent as its transaction is not in the global database.

In older versions of the bitcoin reference code, a miner could make their coinbase transaction (block reward) have the exact same ID as used in a previous block<ref>https://github.com/bitcoin/bitcoin/issues/612</ref>. This effectively caused the previous block reward to become unspendable. Two known such cases<ref>{{cite tx|e3bf3d07d4b0375638d5f1db5255fe07ba2c4cb067cd81b84ee974b6585fb468|used in blocks 91722 and 91880}}</ref><ref>{{cite tx|d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599|used in blocks 91812 and 91842</ref> are left as special cases in the code<ref>https://github.com/bitcoin/bitcoin/commit/ab91bf39b7c11e9c86bb2043c24f0f377f1cf514</ref> as part of [[BIP 0030]] changes that fixed this issue. These transactions were {{btc}}50 each.

==Money Supply==
While the number of bitcoins in existence will never exceed 21 million, the [[wikipedia:money supply|money supply]] of bitcoins can exceed 21 million due to [[wikipedia:Fractional-reserve Banking|Fractional-reserve Banking]].

==Deflation==

Because the monetary base of bitcoins cannot be expanded, the currency would be subject to severe deflation if it becomes widely used.
Keynesian economists argue that [[Deflationary spiral|deflation]] is bad for an economy because it incentivises individuals and businesses to save money rather than invest in businesses and create jobs. The [[wikipedia:Austrian school|Austrian school]] of thought counters this criticism, claiming that as deflation occurs in all stages of production, entrepreneurs who invest benefit from it. As a result, profit ratios tend to stay the same and only their magnitudes change. In other words, in a deflationary environment, goods and services decrease in price, but at the same time the cost for the production of these goods and services tend to decrease proportionally, effectively not affecting profits. Price deflation encourages an increase in hoarding — hence savings — which in turn tends to lower interest rates and increase the incentive for entrepreneurs to invest in projects of longer term.

This chart would benefit from a minimum periodical updating every 52,500 blocks (one quarter of a reward halving period) or approximately once every year. The next update opportunity is at block 420,000 estimated to occur somewhere between June and July, 2016.

More frequent updates may be warranted if the network hash rate sees a sudden and sustained increase or decrease.

Vanitygen

2015-07-26T17:29:27Z

TheRealSteve: /* Expected keysearch rate */

'''Vanitygen''' is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjO.
Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen. It is typical, and takes about 10 sec to finish, using a Core 2 Duo E6600 CPU on x86-64 Linux:
<syntaxhighlight lang="bash">
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
</syntaxhighlight>

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client. Oclvanityminer can be used to automatically claim bounties on sites such as [[User:ThePiachu|ThePiachu]]'s [[Vanity Pool]].

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Radeon 58XX outperforms Radeon 69XX by a very comfortable margin. Oclvanitygen is sensitive to integer multiply throughput, and Radeon 58XX can multiply concurrently with other operations. At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.

== Difficulty of finding a vanity ==
The difficult of finding a vanity address depends on its exact structure (leading letters and numbers) and how likely such an output is given the algorithms involved, which can consist of several pivots where the difficulty suddenly changes.

== Use of vanitygen to try to attack addresses ==
Using vanitygen you might think that you would be able to find the private key for a given address. In practice, this is considered impossible. Given that the difficulty increases exponentially the longer your vanity is, so does the average time required to find that vanity. The example table below shows how an increasingly complex vanity affects the difficulty and average time required to find a match only for that vanity, let alone the full address, for a machine capable of looking through 1 million keys per second.

This article lists Bitcoin-related press from the project's creation through October 2011. Since that time, due to the increased frequency of published articles, a [http://bitcointalk.org/index.php?board=77.0 Press forum board] was created on the BitcoinTalk Forum to allow the wider Bitcoin community to share articles as they are discovered.

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The
[[wikipedia:monetary base|monetary base]] is controlled by a central bank. In the United States, the [[wikipedia:Federal Reserve System|Fed]] increases the monetary base by issuing currency, increasing the amount banks have on reserve, and more recently, printing money electronically in a process called [[wikipedia:Quantitative Easing|Quantitative Easing]].

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

==Currency with Finite Supply==
[[Image:Controlled supply-block reward halving.png|160px|thumb|right| Block reward halving]]
[[Image:Controlled supply-supply over block height.png|160px|thumb|right| Controlled supply]]
Bitcoins are created each time a user discovers a new [[block]].
The rate of block creation is approximately constant over time: 6 per hour. The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of bitcoins in existence will never exceed 21 million.<ref>[http://www.bitcointalk.org/index.php?topic=3366.msg47522#msg47522 21 million cap]</ref> Speculated justifications for the unintuitive value "21 million" are: it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number.

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called [[Mining|''Miners'']].

==Projected Bitcoins Long Term ==
[[Image:Controlled supply-timeline estimation.png|160px|thumb|right| Supply timeline estimation]]
Because the number of bitcoins created each time a user discovers a new block - the block reward - is halved based on a fixed interval of blocks, and the time it takes on average to discover a block can vary based on [[mining]] power and the network [[difficulty]], the exact time when the block reward is halved can vary as well. Consequently, the time the last Bitcoin will be created will also vary, and is subject to speculation based on assumptions.

If the mining power had remained constant since the first Bitcoin was mined, the last Bitcoin would have been mined on October 8th, 2140. Due to the mining power having increased overall over time, as of block NNNNNN, assuming mining power remains constant at that point, the last Bitcoin would be mined on May 19th, 2140.

As it is very difficulty to predict how mining power will evolve going into the future - i.e. whether technological progress will continue to make hardware faster or whether mining will hit a a technological wall, or whether or not faster methods of calculation will be discovered - putting an exact date or even year on this event is difficult as well.

The total number of bitcoins, as mentioned earlier, will tend toward 21 million. Due to a technical limitation in the data structure of the blockchain - specifically of the [[Transaction#general_format_.28inside_a_block.29_of_each_output_of_a_transaction_-_Txout|transaction output]], this exact value is 20,999,999.9769 bitcoin. Should this technical limitation is adjusted, the total number will still only be a maximum of 21 million.

''Note: The number of bitcoins are presented in a floating point format. However, these values are based on the number of satoshi per block originally in integer format to prevent compounding error.''

==Spendable Supply==
The theoretical total number of bitcoins, 21 million, should not be confused with the total spendable supply. The total spendable supply is always lower than the theoretical total supply, and is subject to accidental loss, willful destruction, and technical peculiarities.

===Loss of bitcoin===
Bitcoins may be lost if the conditions required to spend them are no longer known. For example, if you made a transaction to an [[address]] that requires a private key in order to spend those bitcoins further, had written that private key down on a piece of paper, but that piece of paper was lost. In this case, that bitcoin may also be considered lost, as the odds of randomly finding a matching private key are such that it is generally considered impossible.

===Willful destruction of bitcoin===
Bitcoins may also be willfully 'destroyed' - for example by attaching conditions that make it impossible to spend them.

A common method is to send bitcoin to an address that was constructed and only made to pass validity checks, but for which no private key is actually known. An example of such an address is "1BitcoinEaterAddressDontSendf59kuE", where the last "f59kuE" is text to make the preceding constructed text pass validation. Finding a matching private key is, again, generally considered impossible. For an example of how difficult this would be, see [[Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses|Vanitygen]].

Another common method is to send bitcoin in a transaction where the conditions for spending are not just unfathomably unlikely, but literally impossible to meet. For example, a transaction that is made [[Script#Provably_Unspendable.2FPrunable_Outputs|provably unspendable using OP_RETURN]], or uses script operations that requires the user to prove that 1+1 equals 3.

A lesser known method is to send bitcoin to an address based on private key that is outside the [[Private_key#Range_of_valid_ECDSA_private_keys|range of valid ECDSA private keys]]. For example, the address 16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM has a known matching private key of value 0 (zero), which is outside the valid range.

===Technical peculiarities preventing spending of bitcoin===
There are also technical peculiarities that prevent the spending of some bitcoin.

The first {{btc}}50, included in the [[genesis block]], cannot be spent as its transaction is not in the global database.

In older versions of the bitcoin reference code, a miner could make their coinbase transaction (block reward) have the exact same ID as used in a previous block<ref>https://github.com/bitcoin/bitcoin/issues/612</ref>. This effectively caused the previous block reward to become unspendable. Two known such cases<ref>{{cite tx|e3bf3d07d4b0375638d5f1db5255fe07ba2c4cb067cd81b84ee974b6585fb468|used in blocks 91722 and 91880}}</ref><ref>{{cite tx|d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599|used in blocks 91812 and 91842</ref> are left as special cases in the code<ref>https://github.com/bitcoin/bitcoin/commit/ab91bf39b7c11e9c86bb2043c24f0f377f1cf514</ref> as part of [[BIP 0030]] changes that fixed this issue. These transactions were {{btc}}50 each.

==Money Supply==
While the number of bitcoins in existence will never exceed 21 million, the [[wikipedia:money supply|money supply]] of bitcoins can exceed 21 million due to [[wikipedia:Fractional-reserve Banking|Fractional-reserve Banking]].

==Deflation==

Because the monetary base of bitcoins cannot be expanded, the currency would be subject to severe deflation if it becomes widely used.
Keynesian economists argue that [[Deflationary spiral|deflation]] is bad for an economy because it incentivises individuals and businesses to save money rather than invest in businesses and create jobs. The [[wikipedia:Austrian school|Austrian school]] of thought counters this criticism, claiming that as deflation occurs in all stages of production, entrepreneurs who invest benefit from it. As a result, profit ratios tend to stay the same and only their magnitudes change. In other words, in a deflationary environment, goods and services decrease in price, but at the same time the cost for the production of these goods and services tend to decrease proportionally, effectively not affecting profits. Price deflation encourages an increase in hoarding — hence savings — which in turn tends to lower interest rates and increase the incentive for entrepreneurs to invest in projects of longer term.

TheRealSteve: /* Expected keysearch rate */ +GTX 780 Ti

'''Vanitygen''' is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjO.
Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen. It is typical, and takes about 10 sec to finish, using a Core 2 Duo E6600 CPU on x86-64 Linux:
<syntaxhighlight lang="bash">
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
</syntaxhighlight>

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client. Oclvanityminer can be used to automatically claim bounties on sites such as [[User:ThePiachu|ThePiachu]]'s [[Vanity Pool]].

As vanitygen performs a lot of large integer arithmetic, running it in 64-bit mode makes a huge difference in key search rate, easily a 50% improvement over 32-bit mode. If you are using a 64-bit edition of Windows, and not using a GPU, be sure to use vanitygen64.exe.

Radeon 58XX outperforms Radeon 69XX by a very comfortable margin. Oclvanitygen is sensitive to integer multiply throughput, and Radeon 58XX can multiply concurrently with other operations. At similar clocks, a hobbled Radeon 5830 will outperform a Radeon 6970.

In custom builds, CPU performance will be less than expected if the OpenSSL library is an older version (<1.0.0d) or is not built with the appropriate optimizations enabled.

== Difficulty of finding a vanity ==
The difficult of finding a vanity address depends on its exact structure (leading letters and numbers) and how likely such an output is given the algorithms involved, which can consist of several pivots where the difficulty suddenly changes.

Vanitygen

2015-07-20T16:04:20Z

TheRealSteve: /* Expected keysearch rate */ + r9 280x

'''Vanitygen''' is a command-line vanity bitcoin address generator.

If you're tired of the random, cryptic addresses generated by regular bitcoin clients, you can use vanitygen to create a more personalized address.
Add unique flair when you tell people to send bitcoins to 1stDownqyMHHqnDPRSfiZ5GXJ8Gk9dbjO.
Alternatively, vanitygen can be used to generate random addresses offline.

Vanitygen accepts as input a pattern, or list of patterns to search for, and produces a list of addresses and private keys. Vanitygen's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky.

The example below illustrates a session of vanitygen. It is typical, and takes about 10 sec to finish, using a Core 2 Duo E6600 CPU on x86-64 Linux:
<syntaxhighlight lang="bash">
$ ./vanitygen 1Boat
Difficulty: 4476342
Pattern: 1Boat
Address: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
Privkey: 5J4XJRyLVgzbXEgh8VNi4qovLzxRftzMd8a18KkdXv4EqAwX3tS
</syntaxhighlight>

Vanitygen includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. Also included is oclvanityminer, the vanity address mining client.

TheRealSteve: /* Actual Supply is Different From The Tables Here */

{{WikiProject|Economics|quality=C|importance=TOP}}
{{WikiProject|Protocol|quality=C|importance=TOP}}
{{WikiProject|Mining|quality=C|importance=TOP}}
== Do not Resurrect That Stupid Graph ==
Please see my points over at [[File_talk:Total_bitcoins_over_time_graph.png]] which describe why I deleted the graph, and description of a suitable alternative. Seriously, the amount of misleading information that prior graph has disseminated into the public is horrorshow-enormous. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 07:11, 14 September 2014 (UTC)

== Actual Supply is Different From The Tables Here ==
Note that the actual supply is different than what is listed on these graphs due to provably destroyed coins, duplicate coinbase, and underpays; this should be accounted-for in the graphs. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 16:32, 16 September 2014 (UTC)
:I'm not sure if 'destroyed' coins should be taken into account. While they may never become part of transactions again, they were at least created. Duplicate coinbase and underpays are a different matter. I'd like to take these into account in at least the description in one of my graphs (see the talk page for the deleted graph), but would also like to see some source material from which to glean actual numbers. If you, or anybody else, can help out with this, it would be appreciated. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 21:48, 12 April 2015 (UTC)
:I'd still like to see some examples of further technical peculiarities that make existing bitcoin unspendable, as well as examples of bitcoin that actually entered into existence when it shouldn't have (thus raising the maximum), didn't enter into existence when they should have (thus lowering the maximum) and any other case that isn't simple loss or willful destruction. There's a section on this now, so by all means, add there directly [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 12:36, 20 July 2015 (UTC)

== Projected Bitcoins (Long Term) - the numbers ==

The Projected Bitcoins Long Term table in the page uses [[Units|Bitcoin]] unit representation as a floating point number with an 8-digit precision to convey the actual number in [[Satoshi (unit)|satoshi]], which has an integer representation inside the [[Bitcoin Core|satoshi client]].

Each of the values is based on the actual number of satoshi rewarded per block. This reward halves every 210,000 blocks.[https://github.com/bitcoin/bitcoin/blob/master/src/main.cpp#L1179] This halving presents a potential point of confusion; at some point the reward would be 610,351.5 satoshi - which at {{as of|2015|04|04}} cannot exist in the satoshi client's fixed point arithmetic limit.<br />
The value is, instead, truncated to 610,351 satoshi. The total number of satoshi generated during that reward era is thus not <tt>210,000 * 610,351.5 = 128,173,815,000 (<span class="btc">BTC</span>1,281.73815000)</tt>, but <tt>210,000 * 610,351 = 128,173,710,000 (<span class="btc">BTC</span>1,281.73710000)</tt>. The same problem presents itself with any subsequent reward eras .<br />
An earlier version of the table in this page had a single satoshi error in some of the values, likely due to related floating point accuracy issues.[http://www.reddit.com/r/Bitcoin/comments/31g89l/rounding_error_in_the_wiki/]

At the actual last round there should be a total of <tt><span class="btc">BTC</span>20,999,999.97690000</tt>.<br />
If using floating point math throughout, depending on the accuracy and behavior of the floating point calculations, this could end up being calculated as <tt><span class="btc">BTC</span>20999999.99877760</tt>, or a difference of <tt><span class="btc">BTC</span>0.02187764</tt>.<br />
The floating point math approach will tend toward a total supply of <tt><span class="btc">BTC</span>21,000,000</tt>, and a difference from the actual current maximum of <tt><span class="btc">BTC</span>0.0231</tt>.

For technical purposes, the total supply should be noted as <tt><span class="btc">BTC</span>20,999,999.97690</tt> with a reminder that this depends on the current fixed point arithmetic. For colloquial use, <tt><span class="btc">BTC</span>21,000,000</tt> should be acceptable. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 22:01, 4 April 2015 (UTC)

File talk:Total bitcoins over time graph.png

TheRealSteve: /* A new graph based on historical data */

==A new graph based on historical data==

Does anyone think we should include a graph of supply that has been observed since 2009, without a future prediction? [[User:Taras|Taras]] ([[User talk:Taras|talk]]) 14:47, 6 March 2015 (UTC)
:Having recently double-check on the table, then commented on the talk page, of the Controlled Supply page, I did notice a comment about this graph having been deleted. Unfortunately, I can't see what the graph was to consider what was wrong with it. I suppose it mapped the Bitcoin supply over time, rather than over blocks. If that is the case, then I concur with the sibling talk topic, that rather than not having a graph, we could make a ''better'' graph, specifically outlining 1. growth over blocks, 2. time over blocks, and 3. estimates for time based on simple values - i.e. network hash rate is steadily 10% fast, or 10% slow, producing two boundaries at the center of which lies the ideal, and then incorporate the actual historical data + projections based thereon. Actually... why don't I just make that now, upload it off-site, and link to it here for further discussion: [http://imgur.com/kmyJrys,lFzIt0x sample graphs] (two images there).

It only shows accurate historical data, and for our cases should be quite alright. The main problem with the original was that everyone assumed production stopped in 2033 (see the FBI report). [[User:Taras|Taras]] ([[User talk:Taras|talk]]) 03:01, 16 July 2015 (UTC)
::::The down side to that graph is that it's not very informative except if all you want to show is how many Bitcoins have been mined so far.. which is something that changes rather quickly.

:::::I'm all for it then, but I have a suggestion; consider putting the subsidy in a second graph on a log scale, so that it's easier to see how it changes over time?

[[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 12:32, 20 July 2015 (UTC)

==Removing This Stupid Graph==

I have removed all links to this file. Please do not put them back. This graph has convinced people that the last mined reward will be in 2033 or so, when that is completely incorrect. Thanks. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 01:54, 12 January 2014 (GMT)
: What I wouldn't delete out of reflex because of the huge amount of PR and fact-correction I've personally been forced to do as a result of this stupid thing, would be a graph which shows a comparison line that describes compression of the release schedule due to hashrate growth so far, as well as reasonably expected growth into the 2100s. Ideally, events such as 'last Satoshi mined' and "if past growth continues, here is where we will be using the entire energy output of the Earth to sustain bitcoin mining" should be notated with an arrow, and the volume line should '''not''' abruptly end at any point prior. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 07:07, 14 September 2014 (UTC)

We should re-add a similar graph. It makes sense that people would think that the reward would stop increasing after 2033 based on that graph, which is incorrect, but that graph also helps people understand the exponential back-off nature of the reward. It is valuable. I believe that it has done more good than harm and I haven't seen it declared anywhere myself that no more bitcoins will be mined after 2033 unless people are just speaking 'practically'. By the way, if over 99% of bitcoins have been mined by 2033 then for many contexts, like economics, *practically* no more bitcoins are being mined. So in the context of economics and other fields, it is correct to say that no more bitcoins will be mined after 2033.

Separately, the lack of a comparison line that describes the compression of the release schedule due to hashrate growth so far is not sufficient reason to get rid of this graph. When educating the public, sometimes details can be ignored for the purposes of explanation. Demanding that the line be a couple pixels to the left is definitely one of those details that can be ignored. This is evidence that, in deleting this graph, you are behaving like a pedant. Please stop. [[User:Atheros|Atheros]] ([[User talk:Atheros|talk]]) 19:04, 10 October 2014 (UTC)

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The
[[wikipedia:monetary base|monetary base]] is controlled by a central bank. In the United States, the [[wikipedia:Federal Reserve System|Fed]] increases the monetary base by issuing currency, increasing the amount banks have on reserve, and more recently, printing money electronically in a process called [[wikipedia:Quantitative Easing|Quantitative Easing]].

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network. The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

==Currency with Finite Supply==
[[Image:Controlled supply-block reward halving.png|160px|thumb|right| Block reward halving]]
[[Image:Controlled supply-supply over block height.png|160px|thumb|right| Controlled supply]]
Bitcoins are created each time a user discovers a new [[block]].
The rate of block creation is approximately constant over time: 6 per hour. The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every four years. The result is that the number of bitcoins in existence will never exceed 21 million.<ref>[http://www.bitcointalk.org/index.php?topic=3366.msg47522#msg47522 21 million cap]</ref> Speculated justifications for the unintuitive value "21 million" are: it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number.

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called [[Mining|''Miners'']].

==Projected Bitcoins Long Term ==
[[Image:Controlled supply-timeline estimation.png|160px|thumb|right| Supply timeline estimation]]
Because the number of bitcoins created each time a user discovers a new block - the block reward - is halved based on a fixed interval of blocks, and the time it takes on average to discover a block can vary based on [[mining]] power and the network [[difficulty]], the exact time when the block reward is halved can vary as well. Consequently, the time the last Bitcoin will be created will also vary, and is subject to speculation based on assumptions.

If the mining power had remained constant since the first Bitcoin was mined, the last Bitcoin would have been mined on October 8th, 2140. Due to the mining power having increased overall over time, as of block NNNNNN, assuming mining power remains constant at that point, the last Bitcoin would be mined on May 19th, 2140.

As it is very difficulty to predict how mining power will evolve going into the future - i.e. whether technological progress will continue to make hardware faster or whether mining will hit a a technological wall, or whether or not faster methods of calculation will be discovered - putting an exact date or even year on this event is difficult as well.

The total number of bitcoins, as mentioned earlier, will tend toward 21 million. Due to a technical limitation in the data structure of the blockchain - specifically of the [[Transaction#general_format_.28inside_a_block.29_of_each_output_of_a_transaction_-_Txout|transaction output]], this exact value is 20,999,999.9769 bitcoin. Should this technical limitation is adjusted, the total number will still only be a maximum of 21 million.

''Note: The number of bitcoins are presented in a floating point format. However, these values are based on the number of satoshi per block originally in integer format to prevent compounding error.''

==Spendable Supply==
The theoretical total number of bitcoins, 21 million, should not be confused with the total spendable supply. The total spendable supply is always lower than the theoretical total supply, and is subject to accidental loss, willful destruction, and technical peculiarities.

===Loss of bitcoin===
Bitcoins may be lost if the conditions required to spend them are no longer known. For example, if you made a transaction to an [[address]] that requires a private key in order to spend those bitcoins further, had written that private key down on a piece of paper, but that piece of paper was lost. In this case, that bitcoin may also be considered lost, as the odds of randomly finding a matching private key are such that it is generally considered impossible.

===Willful destruction of bitcoin===
Bitcoins may also be willfully 'destroyed' - for example by attaching conditions that make it impossible to spend them.

A common method is to send bitcoin to an address that was constructed and only made to pass validity checks, but for which no private key is actually known. An example of such an address is "1BitcoinEaterAddressDontSendf59kuE", where the last "f59kuE" is text to make the preceding constructed text pass validation. Finding a matching private key is, again, generally considered impossible. For an example of how difficult this would be, see [[Vanitygen#Use_of_vanitygen_to_try_to_attack_addresses|Vanitygen]].

Another common method is to send bitcoin in a transaction where the conditions for spending are not just unfathomably unlikely, but literally impossible to meet. For example, a transaction that is made [[Script#Provably_Unspendable.2FPrunable_Outputs|provably unspendable using OP_RETURN]], or uses script operations that requires the user to prove that 1+1 equals 3.

A lesser known method is to send bitcoin to an address based on private key that is outside the [[Private_key#Range_of_valid_ECDSA_private_keys|range of valid ECDSA private keys]]. For example, the address 16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM has a known matching private key of value 0 (zero), which is outside the valid range.

===Technical peculiarities preventing spending of bitcoin===
There are also technical peculiarities that prevent the spending of some bitcoin.

The first 50 bitcoin, included in the [[genesis block]], cannot be spent as its transaction is not in the global database.

==Money Supply==
While the number of bitcoins in existence will never exceed 21 million, the [[wikipedia:money supply|money supply]] of bitcoins can exceed 21 million due to [[wikipedia:Fractional-reserve Banking|Fractional-reserve Banking]].

==Deflation==

Because the monetary base of bitcoins cannot be expanded, the currency would be subject to severe deflation if it becomes widely used.
Keynesian economists argue that [[Deflationary spiral|deflation]] is bad for an economy because it incentivises individuals and businesses to save money rather than invest in businesses and create jobs. The [[wikipedia:Austrian school|Austrian school]] of thought counters this criticism, claiming that as deflation occurs in all stages of production, entrepreneurs who invest benefit from it. As a result, profit ratios tend to stay the same and only their magnitudes change. In other words, in a deflationary environment, goods and services decrease in price, but at the same time the cost for the production of these goods and services tend to decrease proportionally, effectively not affecting profits. Price deflation encourages an increase in hoarding — hence savings — which in turn tends to lower interest rates and increase the incentive for entrepreneurs to invest in projects of longer term.

Graph of Bitcoin's controlled supply as an estimate against time, depicting the influence of the network's hash rate (continuously faster vs continuously slower) om that timeline.

This chart would benefit from a minimum periodical updating every 52,500 blocks (one quarter of a reward halving period) or approximately once every year. The next update opportunity is at block 367,500 estimated to occur around July 29th, 2015.

More frequent updates may be warranted if the network hash rate sees a sudden and sustained increase or decrease.

Genesis block

2015-07-19T16:10:43Z

TheRealSteve: /* Main network genesis block */ the reuters article is down, replaced with archive.org link. Perhaps restoring the photograph of the physical paper would be good as a secondary reference, though?

A '''genesis block''' is the first block of a [[block chain]]. Modern versions of Bitcoin assign it block number 0, though older versions gave it number 1. The genesis block is almost always hardcoded into the software. It is a special case in that it does not reference a previous block, and for [[Bitcoin]] and almost all of its derivatives, it produces an unspendable subsidy.

== Main network genesis block ==
Here is a representation of the genesis block<ref>{{cite block|hash=000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f|0|year=2009|month=01|day=03}}</ref> as it appeared in a comment in an old version of Bitcoin ([http://sourceforge.net/p/bitcoin/code/133/tree/trunk/main.cpp#l1613 line 1613]). The first section defines exactly all of the variables necessary to recreate the block. The second section is the block in standard printblock format, which contains shortened versions of the data in the first section.

The [[coinbase|coinbase parameter]] (seen above in hex) contains, along with the normal data, the following text:<ref>[http://web.archive.org/web/20140309004338/http://uk.reuters.com/article/2009/01/03/idUKPTIP32510920090103 Reuters' reference on The Financial Times article (archive.org cached copy)]</ref>

<blockquote>The Times 03/Jan/2009 Chancellor on brink of second bailout for banks</blockquote>

This was probably intended as proof that the block was created on or after January 3rd, 2009, as well as a comment on the instability caused by fractional-reserve banking.

The first 50BTC block reward went to [[address]] [http://blockexplorer.com/address/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa], though this reward can't be spent due to a quirk in the way that the genesis block is expressed in the code (this may have been intentional).<ref>http://bitcoin.stackexchange.com/questions/10009/why-can-t-the-genesis-block-coinbase-be-spent</ref><ref>https://www.reddit.com/r/Bitcoin/comments/1nc13r/the_first_50btc_block_reward_cant_be_spend_why/</ref><ref>https://github.com/bitcoin/bitcoin/blob/9546a977d354b2ec6cd8455538e68fe4ba343a44/src/main.cpp#L1668 - Genesis block transaction treated as a special case in the reference code</ref>
