zkSync Token Launch Sparks Backlash Over Airdrop ControversyzkSync announced its token launch date for ZK on June 17, 2024, marking a significant milestone in the blockchain world. With a total supply of 21 billion tokens, the distribution details unveiled a strategic breakdown: 17.5% (approximately 3.675 billion tokens) allocated to early users via a one-time airdrop, 16.1% reserved for the development team, 17.2% set aside for investors, and the remaining tokens assigned to ecosystem initiatives managed by the ZKSync Foundation and ZK Nation governance. The allocation methodology saw 89% of the 17.5% airdropped to significant network transactors and 11% to developers, researchers, and related participants.However, the airdrop quickly faced a storm of backlash due to widespread Sybil attacks, where users manipulated interactions using multiple wallets to qualify for rewards. This manipulation led to nearly 90% of the addresses that interacted with zkSync being excluded from the reward distribution, igniting widespread dissatisfaction among the community. Despite the airdrop targeting 695,000 wallets, critics like "Caneleo" on X suggested a maximum allocation of 20,000 tokens to include more wallets. Another user, "Olimpio," highlighted that 155 wallets had surpassed the 100,000 token cap, with other users suggesting this might be because select addresses eligible for the contribution-based airdrop could receive additional allocations.Basically, the way the zksync team found to fight sybils was by heavily prioritizing assets and LP.More Era on-chain liquidity+More time being a LP = larger allocation.Large bot farms are, on average, not whales, and they transact cyclically with not-so-large capital amounts.… pic.twitter.com/zfl5ekU0Yn— olimpio (@OlimpioCrypto) June 11, 2024 Security experts weighed in on the controversy. Mudit Gupta, Chief Information Security Officer at Polygon Labs, labeled the zkSync airdrop as the "most farmable and farmed airdrop ever" due to its lack of effective Sybil filtering. zkSync airdrop is out. Most farmable and farmed airdrop ever probably. Almost no sybil filtering as far as I can see.Anyone who knew the criteria could've easily farmed the shit out of it.Makes you appreciate what LayerZero is trying to do with sybil filtering.— Mudit Gupta (@Mudit__Gupta) June 11, 2024 Nansen clarified it didn't conduct anti-Sybil checks or advise on ZK token allocations, but provided data on specific wallet segments, including whales and known scammers. Crypto researcher "Ignas" argued that zkSync intentionally avoistrict anti-Sybil measures, citing their press release that claimed such measures often exclude genuine users. zkSync didn't apply strict anti-sybil criteria on purpose:"With 6 million unique addresses on ZKsync Era, it’s tempting to eliminate bot swarms by applying strict sybil criteria.But sybil detection often cuts out real users with arbitrary filters."Onchain history was key. https://t.co/uOq2Puq8SY pic.twitter.com/gnMf3nriGv— Ignas | DeFi Research (@DefiIgnas) June 11, 2024 Adam Cochran, a partner at Synthetix, criticized the airdrop for its poor planning from a Sybil perspective, noting that it made it easy for farmers and difficult for genuine users. I love the zkSync guys but damn that was not a well planned airdrop from a sybil perspective.Those criteria are easy to not hit as a real user, and easy to hit as a farmer, and had no anti-sybil program.Real users could easily use 1-2 dapps or only a handful of tokens on your… pic.twitter.com/PiqprIbKJ3— Adam Cochran (adamscochran.eth) (@adamscochran) June 11, 2024 Adding to this, "Artemis the Sybil Hunter" reported that Sybil accounts managed to bag over 2 million ZK tokens by depositing identical Ethereum amounts on the same day, resulting in 15,000 tokens airdropped to each wallet. Nearly all these accounts were flagged on the LayerZero Labs Sybil list. Shocking data from ZKSync Eligibility ListSybil accounts are bagging 2,000,000+ ZK tokens by depositing identical ETH amounts on the same day, each receiving 15,000 tokens per walletWhat's more, nearly all of them are flagged on the @LayerZero_Labs sybil listLink below pic.twitter.com/hd9uipFzuj— Artemis the Sybil Hunter (@artemis_rsch) June 11, 2024 Further research suggested that the volume of tokens allocated to Sybil users could be over 12.7 million, underscoring the scale of the issue.The announcement had a notable impact on zkSync's Total Value Locked (TVL), which saw a sharp decline from nearly $200 million to approximately $133 million post-announcement, eventually dipping further to around $128 million according to DeFiLlama data. The primary reason for this decline was users withdrawing their assets in protest against the perceived unfairness in the token distribution. One user on X captured the prevailing sentiment: "There are six reasons for not buying zkSync tokens. The secondary investors have officially declared war on VCs and project owners. If we don’t buy, we won’t lose."Market predictions for the ZK token varied widely amidst the controversy. Some speculated that the token could hit $1 at launch, while the Whales Market pre-listing platform showed ZK trading at $0.34. Sentiment analysis by Kaito AI revealed a predominantly negative community sentiment driven by concerns over Sybil attacks, ineligibility issues, and reward disparities.Save yourself precious time.Here's a summary of how CT feels about the zkSync airdrop so far.You're welcome pic.twitter.com/zYHNmsXnjk— Kaito AI (@_kaitoai) June 11, 2024 Despite the backlash, zkSync emphasized its commitment to transparency and community engagement. The team invited further feedback from the community to better align future decisions with user expectations, signaling a willingness to “adapt and address the concerns” raised by the airdrop controversy. ConclusionThe zkSync token launch and airdrop have been met with significant controversy, primarily due to Sybil attacks and the perceived unfairness of the distribution. This has led to a notable decline in TVL and widespread dissatisfaction among the community, reflecting a loss of confidence in the protocol. The project's response to feedback and adjustments in future initiatives will be critical in regaining user trust and stabilizing the network's value.
