Coco enables the ledger to mask all data, including metadata precisely to prevent the leakage you ask about. When a ledger integrates with Coco it decides what capabilities to take advantage of - and how much data to expose to the public, to permissioned participants, to counterparties or to any other role. Similarly, when someone writes a smart contract on top of a ledger, they can take advantage of the confidentiality features to decide what to expose to their callers based on the role of the caller.

We are aiming to enable a decentralized system that behaves the way that enterprises expect the data layer should behave - to only expose data to authorized callers. The cool thing about it being decentralized is that you don't have to trust/pay any one party to run it, and your authorized callers can include many counterparties within a market.

Thanks for the reply!

Just to clarify, is it possible to extract any metadata from the underlying Ether network (if that is being used)?

[MatthewKernerMS]

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?

No, thank you for the explanation. I had a fever yesterday and had details backwards.
