LUMEN · VERIFIED CLEAN COMPUTE-HOUR
Lumen unit inventory
The public home of Lumen. A live inventory of the most recently sealed Verified Clean Compute-Hours (VCCH) — one sealed, portable, conserved unit fusing confidential-compute attestation, 24/7 carbon-free-energy matching and a regime-bound cryptographic seal. Verify once, rely many.
A live shelf of sealed units anyone can check for themselves
Each card below is a unit the conserved ledger has issued, showing its carbon-free fraction, compute state and jurisdictional regime. To check a unit yourself, open the verifier and paste the sealed unit JSON plus the bearing tenant's public key — verification runs entirely in your own stack and needs no trust in, and no lookup against, Certisyn. Operators and owners enter the workspace via operator access.
✓Units are present, attested, and carry high carbon-free fractions. — The market is live and the shelf reflects real sealed issuance.
▲Units show as indeterminate, or carbon-free fractions look low. — Indeterminate means no attestation source reconciled — expected before live compute feeds are wired. Confirm on the operator console.
✕The shelf is empty where issuance is expected, or a unit fails the public verifier. — Confirm the ledger table is migrated and the mint pipeline is reachable, then re-mint or re-check the affected units.

What a unit fuses
Confidential-compute attestation
NVIDIA-CC / Intel-TDX / AMD-SEV-SNP / AWS-Nitro evidence reconciles to one canonical compute-state hash. No sources → indeterminate, never a fabricated "attested".
24/7 carbon-free matching
Hourly carbon-free-energy matching yields a carbon-free fraction (CFE%) and a residual-carbon claim — not annual offsets, hour-by-hour truth.
Membrane seal
A per-record Ed25519 seal bound to a jurisdictional regime, byte-identical to the production seal — so a VCCH verifies in anyone's stack.
