- The verifier requests two claims: avg_steps_30d_over_8000 and period; the page says the step count is not attested by anyone.
Field notes
The described flow reduces a 30-day HealthKit summary to a threshold result and a period claim, with the verifier requesting only those disclosures. The page says the wallet would sign with a Secure Enclave key, but also makes clear that a self-issued credential cannot independently establish whether the step count is accurate; the wallet app and source code are still marked as coming soon.
