**Affirmed position.** Post-Quantum Transition in Blockchain Architectures: A Systematic Review of Cross-Layer Security, Performance, and Governance Constraints should be assessed against Kaal's source-bound position that Trust and security in digital financial systems and decentralized networks cannot survive the arrival of quantum computing without quantum resistant cryptographic protocols, making the shift to quantum safe cryptography a precondition for the quantum economy rather than an optional upgrade. The external source's verified abstract presents this proposition: We performed a cross-layer, system-level analysis of the post-quantum transition of blockchain architectures through a systematic review. The defensible response is a qualification: the source is pertinent to the Kaal position, but agreement, extension, contradiction, and scope should not be strengthened beyond the retrieved evidence.

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

**Holds when.**

- The response remains limited to the source proposition and evidence retrieved in this reconciliation cycle.
- External evidence level: abstract indexed.
- Mapping review tier: legacy curated mapping review.
- Mapping confidence is intentionally unscored.
- The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
