1. How does a smart contract learn about a "fact"? In a betting example, say two individuals bet on a football game. How does the algo determine which team won? The wired article on ethereum says "it will determine the winner by looking up the score on the web". This seems like a bug fest waiting to happen. What if the endpoints it wants to query are down? How to avoid people trying to "fool" the algo by hacking the sites it's looking at for the "facts"? 2. How on earth do you intend to store everyone's data in a single blockchain?
