Everyone asks about the blockchain part. The blockchain part was the easy half. Validators reading USGS, Open-Meteo and AirLabs independently, the median deciding, anything off by more than 5% dropping out, the whole policy firing as a reactive transaction with no keeper of ours sitting in the path. @RialoHQ gave us that. We wrote rules. The network enforced them. The hard half was everything insurance has always been hard at. Which reading counts when a magnitude gets revised three hours after it publishes. What "delayed" means when an airline cancels your flight and rebooks you onto one landing at the same time. How you price a peril in a country where you have no claims history to price from. Where the capital sits before anyone has reason to trust you with a premium. None of that gets solved by being onchain. It gets solved by sitting with a licensed insurer and arguing about definitions until the terms say exactly one thing and cannot be read to say two. That's the part I didn't expect walking in. I assumed the chain would be the obstacle. The chain turned out to be the only component that behaved exactly as documented, every single time.
