If this is a topic you're curious about, look into some of Sergey Nazarov's interviews and/or pay attention to the topic of "cryptoeconomic security" in relation to oracles. Basically the idea is to have a system where the cost of corrupting the information on a network is always far more than the potential gain. Whether or not this is possible or will succeed is a question mark, but I'd think many potential objections and question marks have been addressed.
