title_body: What are oracle services going to look like on Cardano?
upvoted_answer: An early oracle-like service nut.link run by the community is already running. It will not provide data to smart contacts, but various dApps might be able to consume its resources if they can read on-chain data.
  As for real oracle solutions that will be able to provide inputs to smart contacts, we will have a lot of them, from community to IOG.
  In fact, most of the work on oracle pools has already been done by Emurgo, not IOG. And implemented on Ergo.
