If a blockchain solution requires transactions between two corporations to be viewable only to those parties, what is the appropriate network design?

• A. Create a single channel with three public data collections.
• B. Create a single channel with three private data collections.
• C. Create multiple channels for each corporation.
• D. Create a single channel with shared ledger access for all.

Answer: (B)

In a scenario where transactions between two corporations need to remain private and viewable only to those two parties, creating a single channel with private data collections is the most effective solution. This design preserves the confidentiality of the sensitive transaction data while allowing authorized parties access to it. Private data collections in a blockchain facilitate sharing of data among specific members of a channel without making that data visible to all participants in the channel. In this case, by designing a single channel with private data collections, both corporations can interact and transact with each other, while sensitive information remains unseen by any external entities involved in the channel. Utilizing a public data collection, in contrast, would expose transaction data to all members of the channel, thus violating the privacy requirement. Moreover, creating multiple channels for each corporation would complicate data sharing and increase overhead, as the two parties would need to manage interactions across separate channels instead of having a streamlined process in one channel. Lastly, having a shared ledger access for all would completely undermine the need for privacy, making all transactions viewable by each participant in the channel. Therefore, the chosen design of a single channel with three private data collections effectively meets the requirement for exclusive visibility and secure transactions between the two corporations.
