Supply chain attestation is a signed claim about some aspect of software production, such as build origin, dependency state, testing, or policy compliance. It matters because security decisions improve when trust is based on portable evidence rather than undocumented assumption.
What is Supply Chain Attestation?
Attestations can describe who built something, what source revision was used, which checks passed, or whether approved dependencies and policies were in effect. They help policy engines and humans verify software production claims before promotion or deployment.
What Supply Chain Attestation Commonly Supports
Common uses include release verification, policy enforcement, software supply chain assurance, and artifact trust.
Supply Chain Attestation vs. Unproven Software Production Claims
Supply chain attestation provides signed evidence about the production process. Unproven claims rely on trust in process narratives without durable proof.
Frequently Asked Questions
Why are attestations useful?
Because they let systems and reviewers evaluate software trust with machine-readable evidence.
Are attestations only for builds?
No. They can cover testing, approvals, dependencies, provenance, and other release conditions too.
