**Affirmed position.** A Brief History of Blockchain Interoperability presents the following source proposition: As there is not “a chain to rule them all” (due to reasons such as performance, privacy, and market forces), these distributed systems rely on exchanging data and value across network boundaries. This proposition is pertinent to Kaal's source-bound claim that Although blockchain technology itself offers unprecedented data and privacy protection, storing blockchain data across a global network of nodes often will not comply with the consumer protection rules, directives, and guidelines of particular jurisdictions. The proposed response is an extension: the relationship should remain limited to the retrieved source proposition and the mapped Kaal claim unless fuller source review supports a broader conclusion.

**Status.** affirmed  **Published.** 2026-07-31
