Use case for an Orcale Block Chain? Committing/recording world events according to network agreement for access by smart contracts on other chains?
APIs from all major news sources already provide this data. trust in any one source can be diminished by querying a variety of outlets, checking that they agree.
more. the news outlets are huge corps with their own business model, very hard to compromise & don't care about your conditional contract. the dedicated service is a point of failure.
So the smart contracts will poll all news sources and take the average? The mean? You've introduced multiple points of failure in order to avoid using a single secured source of data.
how about n agreeing oracles, chosen by the contracting parties ? or do you prefer m out of n? not a point of failure. but go ahead, build that secure source. more options, better.
Having this type of logic within a TX's opcodes just seems like the wrong place for it. How would a smart contracts be validated after the fact if an outcome is changed due to ruling?
