Download Bitcoin Core Version:

Bitcoin uses peer-to-peer technology to operate, without central authority or central bank; Bitcoin transaction management and issuance is carried out collectively by the network. Bitcoin is open source; the design is general, no one owns and controls Bitcoin and everyone can take part. By its unique nature, Bitcoin allows ways of use that cannot be done by other payment systems before.

Check your bandwidth and remaining storage space

The initial synchronization of Bitcoin Core can take a very long time and download a lot of data. You should make sure that you have enough bandwidth and storage for the block-chain size (more than 200GB). If you have a good internet connection, you can strengthen the network by running Bitcoin Core and opening port 8333.

Bitcoin Core is a project driven by the free software community, released under the MIT license.

How to improve

If you are running an older version, turn it off. Wait until it really dies (which may take several minutes for the older version), then run the installer (on Windows) or simply copy / Applications / Bitcoin-Qt (on Mac) or bitcoind / bitcoin-qt (on Linux)).

Updating directly from the version of Bitcoin Core that has reached EOL is possible, but it may take time if the data needs to be migrated. Old wallet versions of Bitcoin Core are generally supported.


Bitcoin Core is supported and widely tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Bitcoin Core on systems that are not supported.

Bitcoin Core also has to work on most other Unix-like systems but is not often tested on them.

Users running macOS Catalina may need to "right-click" and then select "Open" to open Bitcoin Core .dmg. This is because of the new signing requirements imposed by Apple, which have not been complied with by the Core Bitcoin project.
