Bitcoind: Difference between revisions

Latest revision as of 01:37, 10 June 2019

bitcoind is a program that implements the Bitcoin protocol for remote procedure call (RPC) use. It is also the second Bitcoin client in the network's history. It is available under the MIT license in 32-bit and 64-bit versions for Windows, GNU/Linux-based OSes, and Mac OS X.

As part of Bitcoin Core, bitcoind has been bundled with the original client from version 0.2.6 to 0.4.9, and with Bitcoin-Qt since 0.5.0.

Running

See running bitcoind for more detail and an example of the configuration file.

Bitcoind is a headless daemon, and also bundles a testing tool for the same daemon. It provides a JSON-RPC interface, allowing it to be controlled locally or remotely which makes it useful for integration with other software or in larger payment systems. Various commands are made available by the API.

To use locally, first start the program in daemon mode:

bitcoind -daemon

Then you can execute API commands, e.g.:

bitcoin-cli getinfo

bitcoin-cli listtransactions

To stop the bitcoin daemon, execute:

bitcoin-cli stop

Up to and including version 0.3.19 is the "Satoshi code". The founder retired from development with end of 2010. Here are three URLs given where you still(!) (2013-01-04) can download one of the "original Satoshi codes". So also this Bitcoin release history.

Theory of Operation

bitcoind is a multithreaded C++ program. It is designed to be portable across Windows, Mac, and Linux systems. The multithreaded aspect leads to some complexity and the use of certain code patterns to deal with concurrency that may be unfamiliar to many programmers. Also, the code is aggressive in the use of C++ constructs, so it will help to be fluent with map, multimap, set, string, vector, iostream, and templates. As is typical of a C++ program, a lot of code tends to end up in the header files so be sure to search both the .cpp and .h files when looking for a function.

The client is oriented around several major operations, which are described in separate detailed articles and summarized in the following sections.

Initialization and Startup

Upon startup, the client performs various initialization routines including starting multiple threads to handle concurrent operations.

Node Discovery

The client uses various techniques to find out about other Bitcoin nodes that are currently connected to the network.

Node Connectivity

The client initiates and maintains connections to other nodes.

Sockets and Messages

The client processes messages from other nodes and sends messages to other nodes using socket connections.

Block Exchange

Nodes advertise their inventory of blocks to each other and exchange blocks to build block chains.

Transaction Exchange

Nodes exchange and relay transactions with each other. The client associates transactions with bitcoin addresses in the local wallet.

Wallet Services

The client can create transactions using the local wallet. The client associates transactions with bitcoin addresses in the local wallet. The client provides a service for managing the local wallet.

RPC Interface

The client offers an JSON-RPC interface over HTTP over sockets to perform various operational functions and to manage the local wallet.

User Interface

Bitcoind's current user interface is the command line while it used to be based on wxWidgets. A graphical user interface is now provided by Bitcoin-qt in version 0.5+ for the reference client.

Troubleshooting

I get "Error loading blkindex.dat" when I try to run the client

blkindex.dat is part of the database that stores the local copy of the blockchain which may have become corrupted.

Open the Bitcoin data directory:

Windows: %APPDATA%\Bitcoin
Linux: ~/.bitcoin
Mac: ~/Library/Application Support/Bitcoin/

Make a backup of that entire folder, then delete everything EXCEPT wallet.dat. Start bitcoin again and it will download a fresh copy of the blockchain (WARNING: This will take a long time).

+Up to and including version 0.3.19 is the "Satoshi code". The founder retired from development with end of 2010. [https://bitcointalk.org/index.php?topic=68121.10;wap2/  Here] are three URLs given where you still(!) (2013-01-04) can download one of the [[Satoshi client|"original Satoshi codes"]]. So also this [http://www.antepedia.com/detail/p/237812136.html Bitcoin release history].
+==Theory of Operation==
+bitcoind is a multithreaded C++ program. It is designed to be portable across Windows, Mac, and Linux systems. The multithreaded aspect leads to some complexity and the use of certain code patterns to deal with concurrency that may be unfamiliar to many programmers. Also, the code is aggressive in the use of C++ constructs, so it will help to be fluent with map, multimap, set, string, vector, iostream, and templates. As is typical of a C++ program, a lot of code tends to end up in the header files so be sure to search both the .cpp and .h files when looking for a function.
-=== Bitcoind (CLI) ===
+The client is oriented around several major operations, which are described in separate detailed articles and summarized in the following sections.
-Bitcoind is both a headless daemon and a client for the same daemon.  It also provides a JSON-RPC interface, allowing it to be controlled locally (via bitcoind or another CLI client) or remotely.  [[Original Bitcoin client/API Calls list|Various commands]] are made available by the API.
-To use locally, first start the program in daemon mode:
+===[[Satoshi Client Initialization and Startup|Initialization and Startup]]===
-:bitcoind -daemon
+Upon startup, the client performs various initialization routines including starting multiple threads to handle concurrent operations.
+===[[Satoshi Client Node Discovery|Node Discovery]]===
+The client uses various techniques to find out about other Bitcoin nodes that are currently connected to the network.
+===[[Satoshi Client Node Connectivity|Node Connectivity]]===
+The client initiates and maintains connections to other nodes.
+===[[Satoshi Client Sockets and Messages|Sockets and Messages]]===
+The client processes messages from other nodes and sends messages to other nodes using socket connections.
+===[[Satoshi Client Block Exchange|Block Exchange]]===
+Nodes advertise their inventory of blocks to each other and exchange blocks to build block chains.
+===[[Satoshi Client Transaction Exchange|Transaction Exchange]]===
+Nodes exchange and relay transactions with each other. The client associates transactions with bitcoin addresses in the local wallet.
+===Wallet Services===
+The client can create transactions using the local wallet. The client associates transactions with bitcoin addresses in the local wallet. The client provides a service for managing the local wallet.
+===RPC Interface===
+The client offers an JSON-RPC interface over HTTP over sockets to perform various operational functions and to manage the local wallet.
+===User Interface===
+Bitcoind's current user interface is the command line while it used to be based on [http://www.wxwidgets.org wxWidgets]. A graphical user interface is now provided by [[Bitcoin-qt]] in version 0.5+ for the reference client.
+==Troubleshooting==
+===I get "Error loading blkindex.dat" when I try to run the client===
+<code>blkindex.dat</code> is part of the database that stores the local copy of the blockchain which may have become corrupted.
-Then you can use the same program to execute [[Original Bitcoin client/API Calls list|API commands]], e.g.:
+Open the Bitcoin [[data directory]]:
-:bitcoind listreceivedbyaddress 0 true
-:bitcoind getbalance
-==History==
+* Windows: <code>%APPDATA%\Bitcoin</code>
+* Linux: <code>~/.bitcoin</code>
+* Mac: <code>~/Library/Application Support/Bitcoin/</code>
-* Version 0.3.20 was released for all supported platforms on February 21, 2011<ref>[http://www.bitcoin.org/smf/index.php?topic=3704.0 Version 0.3.20]</ref>.
+Make a backup of that entire folder, then delete everything EXCEPT <code>[[Wallet|wallet.dat]]</code>. [[Running Bitcoin|Start bitcoin]] again and it will download a fresh copy of the [[blockchain]] (WARNING: This will take a long time).
