Odaily Planet Daily News Vitalik Buterin said in an article on the X platform that airdrops are an interesting initial use case for verifying ZK, blockchain identity, credentials, and proof frameworks. He pointed out that the goals of airdrops include: distribution to community members rather than random users who sell immediately; rewarding project contributors; maintaining relative fairness but allowing a certain degree of difference; resisting large-scale gains. These are exactly the characteristics that identity, credentials, and proof frameworks are designed to achieve, so it is reasonable to use token issuance as an initial use case for these frameworks for testing and optimization, especially in adversarial environments.
