A Hyperledger Fabric node that only intends to share data with a subset of nodes in the network can do so through channels. In these cases, only peers that participate in the channel can store transaction data; the peers that are not part of the channel do not have visibility into the transaction data, and thus cannot store it. However, this data is exposed to the ordering service. A robust Channel design will address the isolation, data privacy and confidentiality between participants and controlled/permissioned access with robust audit capability.
