Caelex Perpetua
Compliance you can prove. Orbits you keep private.
PERPETUA turns your satellite telemetry into cryptographically sealed compliance evidence — proof that regulators, insurers, and partners can verify. On the proof path, STARK proving runs on your own infrastructure: your manoeuvre trajectories stay with you, only proofs travel.

STARK Proving — Witness Stays With You
How It Works
From telemetry to sealed proof in three steps
Step 1 · Sentinel
Capture
An edge agent at your ground segment signs your telemetry the moment it arrives, then delivers the signed evidence over an authenticated channel — attributable, hash-chained, and tamper-evident from the first hop.
Step 2 · Ephemeris
Verify
A physics engine checks every reported state against orbital mechanics. Data that could not physically happen is rejected before it enters your record.
Step 3 · Verity
Seal
Verified compliance verdicts are cryptographically sealed and appended to a signed transparency log — auditors check inclusion and consistency against published tree heads.
Built on three subsystems running in the Caelex platform today — Sentinel, Ephemeris, and Verity. The full PERPETUA protocol is in active development.
Why Perpetua
Evidence that stands on its own
Today, orbital compliance runs on self-declared reports that nobody can independently check. PERPETUA replaces trust-me paperwork with verify-it-yourself proof.
Evidence gated by physics
Physics is the gatekeeper. A reported state is admitted only if it is physically reachable from an independently confirmed anchor — physically impossible reports are rejected automatically.
Proof without disclosure
Prove collision-avoidance execution without handing over the manoeuvre: the STARK proof is generated on your own infrastructure, so the committed trajectory never leaves it — only the proof and its public statement travel. Formal zero-knowledge (Groth16 wrap) is on the published roadmap.
Continuous, not annual
Evidence accrues automatically with every pass instead of piling up in a yearly audit sprint. Your compliance record is always current.
Tamper-evident by construction
Every verdict is sealed, signed, and appended to a transparency log with published tree heads — auditors verify inclusion and consistency proofs themselves. Toolchain-free third-party proof verification (Groth16) is on the published roadmap.
Regulator & insurer ready
Share verifiable verdicts for licensing, supervision, and premiums. A proof link replaces a folder of screenshots and self-declarations.
Sovereignty by design
Manoeuvre proving runs on your infrastructure, inside your jurisdiction — the private trajectory witness never crosses the boundary. Admission evidence travels as signed, physics-gated packets you can audit end to end.
Two Worlds, One Proof Standard
Built for commercial constellations and classified missions alike
Civil & Commercial
- Prove disposal and debris-mitigation compliance to licensing authorities — continuously, not once a year.
- Give insurers verifiable operating evidence instead of self-declarations, and negotiate premiums from a position of proof.
- Keep your constellation design and maneuver strategy private while staying fully auditable.
Defense & Government
- Share proof with oversight bodies and allies — never the orbit itself. Capabilities stay classified while verification stands.
- Manoeuvre proving runs on sovereign infrastructure inside your jurisdiction; the private trajectory witness never crosses the boundary — verifiers need only the proof and its public statement.
- Demonstrate responsible-behavior norms in orbit with evidence third parties can check without access to mission data.
