Gitian is a secure source-control oriented software distribution method. This means you can download trusted binaries that are verified by multiple builders.

Gitian uses a deterministic build process to allow multiple builders to create identical binaries. This allows multiple parties to sign the resulting binaries, guaranteeing that the binaries and tool chain were not tampered with and that the same source was used. It removes the build and distribution process as a single point of failure.

The Gitian Builder was previously used by Bitcoin Core for deterministic builds for about 10 years. However, they recently moved to Guix, and this project is now archived.

• A group of builders is much more trustworthy than just one
• Friends don't let friends run untrusted binaries
• Create a secure and easy-to-use software upgrade process
