Decision Certificate · attest → verify → vault
Run the whole loop in 60 seconds.
Issue an Ed25519-signed, chain-hashed certificate for an AI decision, then verify it with no trust in the operator. Sandbox: signing uses a software key and TEE/GPU quotes are simulated (labelled simulated:true); the certificate format is identical in production.
STEP 01 · ATTEST
Issue a Decision Certificate
STEP 02 · VERIFY
Independently verify
Recompute the hashes, check the Ed25519 signature and the append-only chain link — publicly, with no API key.
Step 03 · VeriVault — the append-only chain
Sandbox demo · software-signed, simulated attestation quotes. Production swaps in a PKCS#11 / KMIP HSM and real Intel TDX / NVIDIA CC quotes; the certificate format is unchanged.
