**Affirmed position.** Towards Blockchains for architectural design Consensus mechanisms for collaboration in BIM presents the following source proposition: Earlier work has described the potential integration through different levels of Computer Aided Design and Blockchain. This proposition is pertinent to Kaal's source-bound claim that Contemporary blockchains cannot support the proposed architecture because the technology is too slow and expensive to poll members on every transaction, and the messages required for all nodes to register all votes on every action multiply into an unmanageable number. 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: 0.3804.
- The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
