VERIFRAX — Public Verifier

A static, public verification surface for verifrax.proof.v1 artifacts.
Proofs are generated privately (engine stays private). Verification is public, portable, and offline-capable.

Portable Proofs Copy/paste JSON anywhere

Engine Private No engine code or IP here

Audit Surface Deterministic schema validation

What this repository is

VERIFRAX-verify is the public verifier surface for verifrax.proof.v1 proofs.

• Private: The VERIFRAX engine that generates proofs (IP, internals, implementation).
• Public: This repository, hosting a static verifier UI over GitHub Pages.
• Portable: Proofs are plain JSON. Anyone can validate without repo or engine access.

This repository is intentionally minimal:

• no servers
• no secrets
• no signing keys
• no privileged trust

Live Verifier

URL: https://verifrax.github.io/VERIFRAX-verify/

Verification contract (current)

The verifier validates:

• JSON parses correctly
• schema === "verifrax.proof.v1"
• required fields are present and well-formed
• artifact.sha256 is a valid 64-hex digest
• canonical fields are displayed deterministically

Note: Hash recomputation requires local file access. The verifier intentionally avoids fetching or executing anything remotely.

---

Core invariant

Proofs travel without you.

Once generated, a proof can be shared, archived, or audited without access to:

• the VERIFRAX engine
• the private repository
• any secrets or credentials

---

Proof format

A verifrax.proof.v1 document includes:

• schema
• created_at
• repo
• baseline_tag
• core_dist_hash
• artifact { name, path, sha256 }
• certificate_v1
• verify_ref (this verifier URL)

---

Security and threat model

This repository is a verification surface, not a signing authority.

• No secrets
• No engine internals
• No remote execution

See:

• THREAT_MODEL.md
• CLI_SPEC.md

Deployment

Deployed via GitHub Pages:

• Branch: main
• Folder: /

Roadmap (public verifier)

• Local file upload for SHA-256 recomputation
• Strict canonical field rendering
• Schema version registry
• Anchor visualization (engine-gated)
