There are traditional centralized forms of cannabis insurance they just are very rare. Why can’t you simply use their model and only use the blockchain to hold premiums and claim funds.
Think traditional insurance but instead of a bank we have the blockchain. There would still be underwriters and claims adjusters and all the people needed to support them.
They probably still need to be licensed by the state. The blockchain it’s just financial software… it can’t replace the jobs that people do!
