Verify independently — no Presaid software required
- Fetch the raw proof bundle: /api/v1/verify/c2c41b99…
- 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.
Full specification: /docs/verification-spec — a reference verifier fits in ~40 lines of any language.
