Vitalik Buterin wrote on X Platform that the airdrop is an attractive initial use case for verifying ZK, blockchain identity, credentials, and proof frameworks. The goals of the airdrop include:
Distributing to community members rather than random users who sell immediately;
Rewarding project contributors;
Maintaining relative fairness but allowing a certain degree of difference;
Resisting intentional large-scale profit-taking.
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 to test and optimize, especially in adversarial environments.
