Signed weather & hazard data for parametric insurance triggers.
A parametric payout turns on a defined data value — wind speed, rainfall, a hazard threshold. Dynamic Feed captures the value reported by the named source as a signed record carrying its measurement time; after the fact, anyone can check whether the signed bytes were altered. Dynamic Feed does not calculate, trigger or settle the payout.
A parametric trigger receipt is the signed, dispute-proof record a parametric payout settles against: it attests what an official source reported and what the pinned methodology implies — not physical loss. Example: a Category-1 hurricane wind trigger (wind ≥ 119 km/h) at Miami. Fetch one live, then flip a byte and watch verification fail.

Parametric and index-based cover is only as trustworthy as the data behind the trigger. If the value that decides a payout is self-reported or un-checkable, both sides are exposed. Supported Dynamic Feed paths sign weather, flood or hazard records over exact bytes, retaining the named source and reported time. Anyone can verify signed-byte integrity; a changed signed byte fails verification. A workflow can separately request an RFC 3161 artifact for the record digest, but independent time evidence requires full token, digest-binding and certificate-path validation. Dynamic Feed does not establish that the reported value is correct or decide a payout. It is not an insurer or administrator.
Use it for
- A signed, independent record of the value behind a parametric trigger
- Index-based cat cover where the index value must be re-checkable
- Agriculture / event / energy weather values, captured as tamper-evident evidence
- A dispute-ready record of the conditions a payout turned on
FAQ
What value does signing add to a parametric trigger?
It makes the trigger record tamper-evident. Either party can re-check that the value existed, unchanged, at the stated time and came from Dynamic Feed — instead of trusting a screenshot or a self-reported figure. It evidences the record, not the truth of conditions.
Is the weather data a guarantee of conditions?
No. Many readings are model forecasts, not measurements, and we make no accuracy guarantee about the upstream source. We provide a signed record of what was reported at a time — evidence, not a warranty.
Is Dynamic Feed the insurer or administrator?
No. Dynamic Feed only supplies the verifiable data record. Pricing, policy, trigger calculation and payout decisions are entirely the insurer's or administrator's; we give no insurance or legal advice.
