The problem
A new frontier model lands every week. The accompanying model card makes claims you can't reproduce, ships an eval table you can't audit, and goes silent the moment the next model arrives. Procurement teams approve weights on vibes; deployment engineers learn about backdoors from social media three months later. For regulated, air-gapped, and sovereign deployments, that's not good enough.
What we do
Sovereign Frontier is a public registry of AI artifacts — models, datasets, architectures, optimizers, tools, systems, protocols, and processors — where provenance is cryptographic, not editorial. Each artifact carries signed attestations and a tamper-evident entry in a public transparency log. If a page makes a claim, you can verify it yourself.
The trust ladder
Artifacts move through tiers as evidence accumulates:
- Quarantine — catalogued from the publisher's published hashes, or closed/gated artifacts we can't independently check. Present, hashed, and logged, but not yet verified by us.
- Hardened — Sovereign Frontier has independently downloaded the weights, verified their SHA-256, and run a supply-chain scan mapped to NIST AI RMF / COSAIS — all signed by our own key.
- Sealed — independent third-party domain review. Retired until real external reviewers sign with their own keys; not currently issued.
Demotions and revocations are first-class too: when something is found wanting, the record says so, verifiably.
How it stays honest
Every tier claim is Sovereign Frontier's own attestation, signed by our key and anchored in a Rekor-style transparency log that makes every promotion append-only and auditable — nothing claims attestation it can't prove. You can verify any page, follow a publisher to be notified on new releases, and read the reasoning behind each release on the blog.
Who builds it
Sovereign Frontier is built by NERVOSYS, LLC — focused on verifiable, sovereign, and air-gappable AI infrastructure for organizations that can't take provenance on faith.
