Coco doesn't use any underlying network - it forms the bottom-most layer of a permissioned blockchain network. When a ledger (could be any ledger, Ethereum as in the demo or otherwise) is integrated on top of it, the ledger decides whether to expose metadata or not, and to whom.

Maybe I misunderstand your question?
