just listened to an epicenter podcast about smart contracts in enclaves, sounds likewhat we accomplish with state channels, but they do it more expensive.

Yes its built, university project. As i understand they need a hardware Oracle to guarantee verification and privacy, like we do in state channels. But i only listened to the epicenter podcast, didn't read the paper. Sounds worth checking out though!
Authenticated Data Feeds for Smart Contracts. These 'Town Crier' feeds would act as bridges between smart contracts and websites, srapping data over TLS and feeding to to a smart contract. Relying on sophisticated hardware enclave technology (Intel SGX), one who uses a Town Crier feed would not need to trust its operator as code execution would be guaranteed signed by the hardware.
It reads similar to what an oracle does. It is another kind of oracle. A hardware one. All I'm trying to point out is there are different kind of oracles. And we all might learn from one another without assessing which on is absolutely better, but trying to figure out what fits best for an individual area of application.
