So while I don't really participate in cryptocurrencies anymore I have a basic knowledge of how it all works and have read up on ETH contracts. Couldn't someone create a contract on the ETH network (my terminology might be off) that allows you send a message to contract with a name (maybe more PII), a date, and some amount of ETH to create the system Jim Bell hypothesized? Obviously a big issue would be "death confirmation" as is how do we know X person is actually dead so we can pay out to the "winner"? I imagine it could be done through some kind of majority system but what incentive would other "donators"/"would be killers" have to confirm a death has happened if they aren't the beneficiary? I'm sure someone clever could think of some way to do it...
