Layer 1 · Interactive Verifier

Verify the test results.

The hash chain and per-result recomputation run live in your browser via SubtleCrypto. The sigstore envelope and Rekor inclusion verify against COSIMO's keyless OIDC signing identity. Hardware attestation via NVIDIA Confidential Compute lands with the v1.1.0 TEE re-run.

Verification flow

Seven steps. Six run real cryptographic checks now. One scheduled transition lands with v1.1.0: hardware attestation via NVIDIA Confidential Compute. See inline notes for timing.

Six headline performance results

Each card maps a headline performance result to its verification record and source data. Per-card deep-links from the validation overview focus a single result here.

Run cosign yourself

The same hash chain check with off-the-shelf cosign. No COSIMO software in the path. See the full recipe for the complete eight-step walkthrough.

Move up the stack

Additional Layers of Verification.

You verified the test results. Move up the stack to verify on your data.

Layer 2 Independent Audit
An independent auditor runs the sealed kernel under NDA on your test data. You receive a signed report. We never receive your data.
Request an audit
Layer 3 Black-Box Pilot
We deploy a sealed black-box version in your environment for testing across your full workload. The kernel runs locally. Source stays sealed.
Request a pilot
Layer 4 Kernel License
Full kernel integration under commercial license terms. Production deployment, your engineering team, your infrastructure.
