**Affirmed position.** Blockchain and How It Relies on Cryptographic Methods presents the following source proposition: A Python-based proof-of-concept demonstrates hashing’s pivotal role in linking blocks, ensuring resistance to tampering. This proposition is pertinent to Kaal's source-bound claim that Cryptographic hashing makes tampering with blockchain records extremely difficult because even a minuscule change produces a different hash value, rendering manipulation instantly and readily detectable. 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

**Holds when.**

- 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: 0.3951.
- The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
