**Affirmed position.** Crypto airdrops: An evolutionary approach presents the following source proposition: This paper argues that coevolutionary theory can help us to understand the unique phenomenon of airdrop design, where participants (projects and users) strategically adapt over time and across different blockchain ecosystems. This proposition is pertinent to Kaal's source-bound claim that To date no blockchain coherently and comprehensively combines scale, security, and decentralization, the three objectives of the blockchain trilemma, although continued experimentation with consensus algorithms can help overcome it over time. 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: 0.3563.
- The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
