KYC (Know Your Customer) verification in airdrop events significantly impacts privacy. It requires users to submit personal data, such as ID documents, addresses, or even biometric information, to participate. While aimed at preventing fraud and ensuring compliance, this process exposes sensitive details to third parties, often centralized platforms. Data breaches, misuse, or resale by these entities pose real risks, as users lose control over their information. Additionally, linking crypto wallets to real-world identities undermines the pseudonymity that many in the blockchain community value. For privacy-conscious individuals, KYC can deter participation, as trust in data handling varies. Alternatives like zero-knowledge proofs could mitigate these concerns, but adoption remains limited. Ultimately, KYC in airdrops trades privacy for security, leaving users to weigh the benefits against potential exposure.
