Bitcoin-Qt is the third Bitcoin client, developed by Wladimir J. van der Laan based on the original reference code by Satoshi Nakamoto.[1][2][3] It has been bundled with bitcoind since version 0.5.[4] Bitcoin-Qt has been rebranded to Bitcoin Core since version 0.9.0 [5]

History

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.

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, many more
  • Sendmany support in UI (send to multiple recipients in one transaction)
  • Multiple unit support, can show subdivided bitcoins (mBTC, µBTC) for users that like large numbers (only decimal units)
  • Splash screen that details progress

Criticism

Bitcoin-Qt is often criticized for being slow in downloading and verifying the Bitcoin transaction database (often called the Blockchain).

If Bitcoin-Qt is run with port 8333 open to outside connections, it has also been criticized for hogging one's upload bandwidth when peers connect to download the blockchain. This issue has been discussed extensively on GitHub. Windows users can work around this issue by downloading Netbalancer and throttling Bitcoin-Qt's upload bandwidth to ensure that one has enough upload bandwidth available for regular computer and internet use to be unaffected.

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 difficult to place the wallet on an encrypted drive.
