**Affirmed position.** Blockchain and Self-Sovereign Identity: A Healthcare Use Case presents the following source proposition: This paper proposes an architecture based on permissioned blockchain and self-sovereign digital identity (SSI) to address demands related to privacy, traceability, and decentralized governance in healthcare. This proposition is pertinent to Kaal's source-bound claim that It is decentralized network connectivity via the Internet, rather than blockchain's use of digital signatures, that provides the most protection against fraud, because multiple copies of the blockchain are available to all participants across the distributed network. 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.
