The Original Bitcoin client is the first bitcoin client in the network's history. It is also the official client of the bitcoin project. It's available under the MIT license for Windows, 32 and 64-bit GNU/Linux-based OSes and Mac OS X.
The client comes with two executables, a GUI and an command line interface (CLI).
See running bitcoin for more detail and an example of the configuration file.
The bitcoin GUI provides an easy to use wxWidgets-based interface, allowing to receive and send bitcoins.
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. Various commands are made available by the API.
To use locally, first start the program in daemon mode:
- bitcoind -daemon
Then you can use the same program to execute API commands, e.g.:
- bitcoind listreceivedbyaddress 0 true
- bitcoind getbalance
- Version 0.3.20 was released for all supported platforms on February 21, 2011.
