Bitcoin-Qt is the first Bitcoin client, developed by Satoshi Nakamoto under its original name Bitcoind.[1][2][3]

The Bitcoin-Qt GUI was initially designed by Wladimir J. van der Laan. It is now maintained by the contributing developers of Bitcoind, which it has been bundled in since version 0.5.[4]


Historically, Bitcoin-Qt supported the mining of the Bitcoin currency; however, this feature has been since redacted due to increased computing requirements and the obsolence of regular CPU power.

Currently, Bitcoin-Qt can 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 Bitcoin GitHub page.
