The Ethereum-based layer-2 scaling solution zkSync has defended the criteria set for its forthcoming ZK token airdrop scheduled for June 17, amid user criticisms and questions about Sybil attack safeguards. The platform addressed these issues in its frequently updated FAQ document, in which it explained its methods for reducing Sybil attacks – the practice of creating multiple wallets to exploit airdrops.
zkSync underscored the use of explicit Sybil detection and a unique airdrop design that would cater to a high count of genuine users but might also permit a few Sybil wallets. The platform explained that advanced Sybils use algorithm-driven strategies that appear human-like and indistinguishable from real actions, making them difficult to thoroughly eliminate.
Refining its approach to reward real users, zkSync incorporated value scaling and multipliers in its method, assigning fewer eligibility points to low-funded wallets that indicated Sybil-like behavior and providing them a multiplying boost for on-chain activities that reflected human action. The company noted that while it’s likely every airdrop will contain some Sybils, measures were taken to ensure only a minimal number slipped through.
In related news, cryptocurrency exchange Binance announced plans for its own ZK token airdrop, aimed at users who did not qualify for zkSync’s official airdrop. Binance is set to offer 10.5 million ZK tokens to more than 52,000 users, each receiving 200 ZK tokens. The airdrop is thought to offer consolation to users amid discontent over the official ZK token distribution.
Binance users eligible for this disbursement should have performed at least 50 transactions on zkSync Era between February 2023 and March 2024, transacted at least seven times during that period, and must not be a centralized exchange, bridge or contract address. Furthermore, they should not have been eligible for the official airdrop. Binance will also initiate ZK token trading starting June 17, featuring trading pairs with Bitcoin and First Digital USD (FDUSD). According to Whales Pro, zkSync’s ZK tokens were pre-market trading at $0.36 at the time of reporting.
