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, timestamped, archived record; after the fact, anyone can check it hasn't been altered since capture. Dynamic Feed does not calculate, trigger, or settle the payout.

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. Dynamic Feed signs each weather, flood or hazard value over its exact bytes — recording the value reported by the named source, which may be a measurement or a model forecast — stamps it with source and exact time, archives it append-only, and can anchor it to Bitcoin. After capture, anyone can verify the record wasn't altered; a single changed byte fails verification. Dynamic Feed evidences the record's integrity and time of capture — not that the value is correct, and not the payout decision. It is not a guarantee of conditions, does not certify the trigger event, and Dynamic Feed 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.
