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

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 on the Bitcoin GitHub page.

Naming Controversy

Some people like Peter Todd, Luke-jr and Greg Maxwell warned against the renaming to Bitcoin Core because it implied a centralization.[4][5][6].

Bitcoin Core right now may be the most popular or "reference" full node implementation, but that status depends on the economic majority continuing to use it[7]. Should one day come where another implementation overtakes it economically, that implementation would become the reference implementation. In one situation in 2017 significant parts of the economy moved to the BIP148 UASF implementation[8] and then moved back to Core after BIP148 was successful. The point here is that Bitcoin Core does not control bitcoin and the naming "Core" is misleading in that respect.

On the other hand, many people are happy with the name Bitcoin Core and continue to use it. As long as it's emphasized that Bitcoin Core is just one possible software implementation of bitcoin that people are free to use or not use.
