From my understanding, one of the major benefits of Qubic is the ability for Oracles to automatically trigger contracts. I'm guessing this will be done with some form of Reactive programming. Is there any sort of corresponding capability in Ethereum. I stopped following Ethereum way back when I learned of IOTA, but I remember there were discussions about having other Ethereum-based projects to provide Oracle functionality. My question is whether it's possible to have an Ethereum contract automatically executed like that. If so, then is there still anything unique about Qubic that cannot be done in Ethereum?
