Concerns over Token Distribution
ZkSync, an Ethereum scaling solution, recently announced an airdrop of its ZK token. However, the community has expressed concerns about the lack of anti-Sybil filtering and the perceived unfairness in token distribution.
Some users have reported receiving low allocations despite being active long-term users. Others were ineligible for the airdrop despite meeting the criteria.
Lack of Anti-Sybil Filtering
Critics have pointed out that the airdrop criteria allowed for “farming,” where individuals could easily create multiple accounts to increase their token allocation. This lack of anti-Sybil filtering has been criticized as allowing bots to exploit the airdrop.
Nansen’s Role
Some users initially blamed the crypto analytics firm Nansen for the lack of anti-Sybil filtering. However, Nansen has clarified that they were not involved in the ZK airdrop and only provided data to ZkSync’s developers.
ZkSync’s Response
ZkSync has defended its decision not to use anti-Sybil criteria, arguing that it could have unfairly excluded real users. Instead, they opted for a “human-first” approach to identify eligible users.
Sybil Wallets
According to estimates, Sybil wallets could receive a significant portion of the airdrop. However, ZkSync has since discarded the list of Sybil wallets used to make these estimates.
