Overview
South Korea's leading meteorological service and big-data company Kweather (KOSDAQ-listed) delivers verified sensor data (temperature, rainfall, atmospheric conditions) onto Flare via the Flare Data Connector (FDC). This powers parametric climate insurance and weather derivatives where claims are settled automatically without human adjusters.
How It Works: Technical Workflow
- 1Kweather streams real-time environmental data from thousands of IoT weather stations and official meteorological APIs.
- 2Independent FDC attestation providers verify the authenticity and finality of the raw Web2 HTTPS API responses.
- 3Attestation results are bundled into an immutable Merkle Tree root committed to Flare approximately every 90 seconds.
- 4Smart contracts autonomously verify conditions (e.g., heatwaves >35°C for 3 consecutive days, rainfall >100mm) and trigger instant payouts to farmers and enterprises.
Real-World Impact
Eliminates manual claims adjustments and paperwork that traditionally took weeks to months. Farmers, solar/wind energy producers, and logistics operators can hedge severe climate risks with guaranteed, transparent on-chain liquidity.
Why Flare Was Chosen
FDC's decentralized Web2 API attestation allows smart contracts to trustlessly consume public and commercial big-data APIs without relying on centralized oracle middle-men.
