Build Attestation Types

OSS Rebuild generates several types of build attestations to provide comprehensive verification of the rebuild process.

Available Attestation Types

• Rebuild@v0.1 - Attests to the build process that reproduced the upstream artifact, including inputs, build definition, and builder details.
• ArtifactEquivalence@v0.1 - Attests to the comparison between the rebuilt artifact and the upstream version.
• NetworkRebuild@v0.1 - Attests to network-based rebuild processes.

For more information on how to access and verify these attestations, see our Storage and Access guide.
