Verify independently — no Presaid software required
- Fetch the raw proof bundle: /api/v1/verify/9ba2267b…
- Recompute
sha256(canonical_payload ‖ salt)and compare it with the commitment hash; fold the Merkle path to the batch root. - Read the ledger transaction above with any public RPC endpoint: its calldata is exactly the batch root, and its block timestamp is the anchored time.
