> how you would build a blockchain based business What problems does a "blockchain based business" solve? That's what I don't understand. Most businesses out there derive value by interacting with off-chain, real-world state. If you wanted to use a blockchain in this case you'd need some trusted party to sync the blockchain state with the state of the real world, which then nullifies most/all of the advantages of using a blockchain over just letting this trusted party run an old school database.
