ZKSync’s airdrop innovations include its use of zero-knowledge rollups for scalable, low-cost Ethereum transactions and a unique eligibility model rewarding genuine user activity over volume. By distributing 17.5% of ZK tokens (3.675 billion) to 695,232 wallets in June 2024, it prioritizes organic engagement—bridging assets, holding duration, and ecosystem contributions—while capping allocations at 100,000 ZK to limit whale dominance. This encourages broader participation, boosting user involvement by favoring committed explorers over Sybil farmers. However, stricter criteria and advanced Sybil detection may exclude casual users, balancing fairness with accessibility.
