TrustSignal - Evidence integrity infrastructure

by•
TrustSignal introduces a receipt-based verification model for compliance evidence and software artifacts. Instead of storing screenshots or logs as proof, it generates signed receipts tied to artifact hashes during CI/CD. These receipts allow anyone to later verify the integrity and provenance of evidence independently of the platform, providing cryptographic assurance that artifacts used in compliance or releases have not been altered.

We built TrustSignal to solve a problem most compliance and DevSecOps teams quietly struggle with: proving that evidence and build artifacts haven’t been tampered with. Today, most compliance evidence is just stored screenshots, logs, or exported reports. Once they’re collected, there’s often no cryptographic proof that the artifact being reviewed later is the same one that originally existed. TrustSignal introduces a receipt-based verification model. During CI/CD, artifacts are hashed and a signed verification receipt is generated. That receipt can later be used to independently verify the integrity and provenance of the artifact. The goal isn’t to replace compliance platforms. It’s to add a verifiable integrity layer for evidence and software artifacts. If you work in DevSecOps, compliance automation, or software supply chain security, I’d love to hear: • Where do you currently store compliance evidence? • Do you have a way to verify that evidence hasn’t changed? • What would make artifact verification useful in your pipeline?
