According to ChainCatcher, Ethereum co-founder Vitalik Buterin said at X that airdrops are an interesting initial use case for verifying zero-knowledge proofs (ZK), blockchain identities, credentials, and proof frameworks.

He pointed out that the goals of airdrops include: distributing to community members rather than random users who sell immediately, rewarding project contributors, maintaining relative fairness (allowing a certain degree of difference), and resisting malicious extractive arbitrage. Vitalik believes that these are exactly the characteristics that identity, credentials, and proof frameworks are designed to achieve, so it is reasonable to use token issuance as the initial use case for these frameworks for testing and optimization, especially in adversarial environments.
