Bitcoin Improvement Proposals

2016-02-12T02:27:42Z

Spaz926: Added BIP2, BIP74, BIP80 BIP81, BIP83, BIP109, BIP124, BIP131, BIP132, BIP145; Changed status of BIP101

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 [https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev the mailing list]. After discussion they should email Luke Dashjr <luke_bipeditor@dashjr.org>. 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]]).

Bitcoin Improvement Proposals

2015-12-03T17:05:48Z

Spaz926: Added 123 and 130

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 [https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev 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]]).

Spaz926: /* Adding BIPs going forward */

The article can be edited only by the administrator.

There are additional BIPs here in the Wiki but not on this article. The [[:Category:BIP|BIP category]] lists some of them. {{unsigned|Sgornick|18:09, 15 April 2012‎}}

== Adding BIPs going forward ==

While I think it's good to have a page explaining what BIPs are and a list of the BIPs on the wiki, perhaps it's best if individual BIPs are no longer added here - linking instead to the official entry for the BIP externally. I have added BIP67 to the list and made just such a link, rather than adding another stub. If anybody disagrees, they're welcome to add the stub as well, but perhaps there should be some discussion on this. [[User:TheRealSteve|TheRealSteve]] ([[User talk:TheRealSteve|talk]]) 14:52, 13 June 2015 (UTC)

: Since the individual BIPs are changing constantly it'd be near impossible to keep each page updated successfully. The template is already in place to link to the github pages. We could keep updating the table just linking to the Github instead of the wiki pages. I think it's a good idea, Steve.

Spaz926: fix typo

'''Bitcoin Core''' (formerly '''Bitcoin-Qt''') is the third [[Bitcoin]] [[Clients|client]], developed by [[Wladimir J. van der Laan]] based on the original reference code by [[Satoshi Nakamoto]].<ref name="Bitcoin Client Software">{{cite web|title=Bitcoin Client Software|url=http://bitcoin.org/clients.html|publisher=Bitcoin.org|accessdate=21 October 2012|quote=The original software written by Satoshi Nakamoto, the project's founder.}}</ref><ref>http://gavintech.blogspot.co.uk/2012/03/full-disclosure-bitcoin-qt-on-windows.html, Full disclosure: Bitcoin-Qt on Windows vulnerability, 21st October 2012</ref><ref>http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2012-4682, Vulnerability Summary for CVE-2012-4682, 21st October 2012</ref> It has been bundled with [[bitcoind]] since version 0.5.<ref name="Bitcoin-Qt/Bitcoind Releases">{{cite web|title=Bitcoin-Qt/Bitcoind Releases|url=http://bitcoin.org/news.html|publisher=Bitcoin.org|accessdate=21 October 2012}}</ref> Bitcoin-Qt has been rebranded to '''[[Bitcoin Core]]''' since version 0.9.0 <ref name="Rebranding to Bitcoin Core">{{cite web|title=Bitcoin Core version 0.9.0 released|url=https://bitcoin.org/en/release/v0.9.0|publisher=Bitcoin.org|accessdate=19 March 2014}}</ref>.

==History==

Bitcoin Core can be used as a desktop client for regular payments or as a server utility for merchants and other payment services.

===Current version===
Source code (and build instructions for supported platforms) can be found at the [https://github.com/bitcoin/bitcoin Bitcoin GitHub page].

==Features==
* Compatibility with Linux (both GNOME and KDE), Mac OS X and Windows
* All functionality of the original wxWidgets client
* Asks for confirmation before sending coins
* CSV export of transactions
* Clearer transaction list with status icons and real-time filtering
* Progress bar on initial block download
* Languages: Dutch, English, German, Chinese and many more. Translations are being done by volunteers on [https://www.transifex.com/projects/p/bitcoin/ Transifex].
* Sendmany support in UI (send to multiple recipients in one transaction)
* Multiple [[Units|unit]] support, can show subdivided bitcoins (mBTC, µBTC) for users that like large numbers (only decimal units)
* Splash screen that details progress
* Debug window
* Payment requests (BIP 70)
* Coin control
* bitcoin-cli as a RPC client, instead of bitcoind executable functioning both as a server and as a RPC client

==Criticism==

===Sync time===
Bitcoin Core is often criticized for being slow in downloading and verifying the Bitcoin transaction database (the [[blockchain]]). The download may be quicker using the [https://bitcointalk.org/index.php?topic=145386.0 bootstrap method]. '''NOTE:''' As of version 0.10.0 it is now slower to download the blockchain via the torrent than it is to download the full blockchain through the P2P client.

===Bandwidth use===
It has also been criticized for "hogging" upload bandwidth when peers connect to download the blockchain (possible only when run with port 8333 accessible to outside connections).
This perceived "issue" has been [https://github.com/bitcoin/bitcoin/issues/273 discussed extensively on GitHub].
Most modern routers support quality-of-service that can be configured to properly share the internet connection across all services, and even deprioritise Bitcoin traffic.
Bitcoin Core includes a script for Linux to configure QoS on an individual host.
Windows users can also use third-party software such as [http://seriousbit.com/netbalancer/ Netbalancer] to throttle the application's upload bandwidth and ensure that one has enough upload bandwidth available for regular computer and internet use to be unaffected.

===Lack of multiwallet support; node+wallet tied together===
Wallet management is also cumbersome. Unlike clients such as [[Armory]], [[MultiBit]], [[Electrum]] and others only one wallet at a time is supported, and its location is required to be the same as the blockchain storage, making it [[Securing_your_wallet#Making_a_secure_workspace|difficult to place the wallet on an encrypted drive]]. It is recommended to backup the wallet.dat file every 50 transactions, due to the way Bitcoin Core handles [[Change|change]].
