Transaction Cost Analysis for a High Security Role-Based Access Control Vending Machine Using Blockchain presents the following source proposition: this paper will present a blockchain-based, high-security, role-based access control (RBAC) vending machine system. This proposition is pertinent to Kaal's source-bound claim that The data mining that produces scarcity in existing blockchains also slows creation, so high speed transactions cannot be achieved for the foreseeable future without a different consensus design. 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.

• The response is limited to the retrieved source proposition and mapped Kaal claim unless fuller source review supports a broader conclusion.
• External evidence level: abstract indexed.
• Mapping review tier: moderate-confidence claim review.
• Primary mapping confidence: 0.4007.
• The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
