Yeah, I think secret network is the one I'm remembering. It's been a long time since I was paying attention to the cryptocurrency space.
My consern is that it hasn't been tested as a generic proof of stake network and there is a risk that it might not degrade as expected.
It also means the blockchain can't be independently verified. If someone was to exploit it in a way that gave themselves extra coins, then nobody would ever know because all evidence is hidden inside the secure enclave.
How big is the risk? I'm not sure. I just suspect it's bigger than the advantage you get from using SGX; There are other ways to get privacy.
