What Are the Differences Between Channel Isolation and Privacy Protection?

Channel isolation: A channel isolates the ledger data of a transaction from other transaction data in a consortium blockchain to ensure confidentiality. Each channel can be considered a sub-blockchain and corresponds to a specific ledger. The ledger in a channel is invisible to other channels.

Privacy protection: Privacy is ensured within each channel because different members in a channel can have different access permissions. For example, member A has the permissions to access certain data, but member B, who does not have relevant permissions, cannot access the specified data.

In short, privacy protection isolates data for a member from other members in same channel, while channel isolation isolates data for all members in a channel from other channels.
