Decentralized identity (DID) solutions enhance 2025 airdrop security by eliminating Sybil attacks through unique, blockchain-verified identities, ensuring one-person-one-wallet compliance. Users prove eligibility without exposing sensitive data via zero-knowledge proofs, reducing phishing/breach risks. Smart contracts auto-validate DID credentials (e.g., KYC status, activity history), minimizing manual checks and human error. Interoperable standards like W3C Verifiable Credentials enable cross-platform trust, preventing duplicate claims while preserving privacy. Token-gated access tied to DID reputations discourages bot-driven exploitation. Immutable audit trails on-chain ensure transparent, tamper-proof eligibility verification. By shifting control to users and embedding trust in code, DIDs reduce fraud vectors central to traditional airdrop systems.
