Bitcoin Core Open Source Release Process

Releases to the Bitcoin Core client and project are built and released using this process:

  • Labeled in github
  • Binaries are created for the platforms affected (usually all, Windows, Mac and Linux).
  • Binary file checksum(s) is(are) calculated and a message with those are signed by a core developer.
    • sha256 checksum
  • Files used to build are checksummed and submitted to the Gitian.sigs project on github.
  • Uploaded to distribution (, and for the Ubuntu PPA)
  • Blog post on
  • Forum post (sticky) on

Verifying The Download

To verify the checksum for a binary download, first ensure the checksum file is secure by decrypting the SHA256SUMS.asc file:

$ gpg --decrypt SHA256SUMS.asc 

Then verify the file checksum:

$ openssl dgst -sha256 [binary release archive] 

Verify that the checksum matches the one in SHA256SUMS.asc

A script to verify the binaries was contributed to the project.
