In IBM Blockchain, what does the term "channel" refer to?

In IBM Blockchain, the term "channel" refers to a private communication link between a specific group of network participants. Channels are essential for ensuring that the communication and transactions among a selected group of participants (such as organizations or individuals) remain confidential. By using channels, blockchain networks can isolate data and transactions, allowing only authorized participants to view or interact with that information. This enhances security and privacy in multi-party environments, enabling tailored access control and governance models for different use cases within the same blockchain network.

The concept of channels is particularly important in permissioned blockchains, as it helps maintain the integrity of sensitive information while allowing multiple users to collaborate without exposing their data to the entire network.
