Kweather, one of South Korea’s largest weather big data platform companies, announced on Tuesday that it will partner with blockchain network Flare to bring weather data on-chain and test new weather finance applications based on a newly signed letter of intent.
As part of this effort, Kweather’s weather datasets, including temperature, precipitation, and other climate variables, will be made available through Flare’s Time Series Oracle.
Layer 1 blockchain projects say their infrastructure validates and protects data, making it immutable and suitable for financial products and blockchain-based services that rely on trusted, real-world information.
Validated data could form the basis of potential climate finance products, such as parametric climate insurance that automatically starts paying out when certain environmental standards are reached, eliminating the need for traditional claims processing.
“Kweather is the perfect partner to work with Flare’s data-centric blockchain ecosystem. We will rapidly advance technology implementation and demonstrate the viability of the weather finance market,” Flare co-founder Hugo Philion commented on the partnership.
The companies also plan to evaluate weather derivatives as tools for managing climate change across sectors such as agriculture, energy and transportation.
“By integrating weather data with blockchain infrastructure, we are transforming weather indicators into reliable on-chain data,” said Dong-sik Kim, CEO of Kweather. “By proactively introducing financial products that manage climate risks, we aim to expand the weather industry market and establish new global standards.”
Additionally, Kweather and Flare plan to develop a decentralized physical infrastructure network by integrating weather monitoring equipment and blockchain infrastructure.
Revenues from the network can be tokenized as real-world assets, and there are plans to connect the platform to the XRP ecosystem through Flare’s blockchain technology in the future.
