This page fetches the live a11oy receipt lake and recomputes every receipt's
chain_hash locally — the exact
SHA3-256(canonical_json{prev_hash, receipt_id, organ, ts, chain_index})
the ledger commits — then checks that each prev_hash links to the previous
chain_hash. Green means the chain is intact as measured on your machine,
not as merely claimed by the server.
MEASURED — recomputed in your browser
REPORTED — asserted by the lake, not re-checked here
UNAVAILABLE — no live data / capability absent
Honest scope. This verifier proves the SHA3-256 hash-chain integrity in-browser
(MEASURED). It does not verify each receipt's DSSE ECDSA-P256 signature — those are
shown as REPORTED. Full signature verification (against the org
cosign.pub)
is the end-to-end cookbook recipe
“Verify a receipt end-to-end”.
Energy is
{"label":"UNAVAILABLE"} unless a real NVML/joules reading exists — never fabricated.
The Khipu chain is Conjecture 2 (advisory BFT), not a proven theorem; Λ remains Conjecture 1.
