**Affirmed position.** Security Challenges and Defense Strategies in Blockchain Systems presents the following source proposition: In the general use of blockchain technology, its decentralization, transparency, and immutability have demonstrated significant value in fields such as finance, logistics, healthcare, and public administration. This proposition is pertinent to Kaal's source-bound claim that Blockchain technology lowers transaction costs by eliminating intermediaries, and it substitutes immutability and cryptography for the trust that intermediaries previously supplied. 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
