Ethereum’s layer-2 scaling platform, zkSync, has been facing criticism regarding the criteria for its upcoming zkSync (ZK) token airdrop scheduled for June 17. In a recent update to its frequently asked questions (FAQ) document on June 15, ZK Nation responded to 15 questions explaining the eligibility criteria for the token distribution.
One of the detailed answers provided by ZK Nation focused on the measures taken to detect and prevent Sybil attacks, where one entity creates multiple wallets to exploit an airdrop. This has been a major concern among airdrop claimants in recent times. ZkSync emphasized that it had implemented explicit Sybil detection and a unique airdrop design to ensure genuine users were rewarded, although some Sybil wallets may have slipped through the cracks.
The explanation further delved into the sophisticated strategies employed by some Sybils, making them indistinguishable from real users. ZkSync mentioned the challenges of filtering out Sybils without falsely flagging genuine users, opting instead to reward organic users through a combination of value scaling and multipliers based on onchain behavior that signals human activity.
Highlighting the differences in funding behavior between Sybils and real users, ZkSync pointed out that while Sybils create multiple accounts with minimal funding, real users tend to consolidate their wealth in a few accounts with larger balances. Despite the presence of Sybils in every airdrop, ZkSync assured that for every identified case, hundreds were excluded.
In response to ongoing concerns surrounding the ZK token distribution, cryptocurrency exchange Binance announced its own ZK airdrop for users not eligible for the official distribution. Over 52,000 Binance users will receive a total of 10.5 million ZK tokens, with each user receiving 200 ZK. Additionally, Binance will enable trading of the ZK token against Bitcoin, Tether, and First Digital USD starting from June 17.
As the ZK token airdrop approaches on June 17, the token is currently trading in the pre-market for $0.36. In related news, the distinction between “Bitcoin Layer 2s” and true Layer 2 solutions is highlighted, emphasizing the significance of this distinction in the cryptocurrency ecosystem.
