Release process

Bitcoin Open Source Release Process

Releases to the Bitcoin.org client 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.
• Files used to build are checksummed and submitted to the Gitian.sigs project on github.
  • sha256 checksum
• Uploaded to sourceforge
• Blog post on Bitcoin.org
• Forum post on BitcoinTalk.org

Verifying The Download

To verify the checksums, 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
