The latest update reflects the results of an in-depth appeal review process, aimed at refining the detection of Sybil activities – where multiple accounts are created to manipulate incentives or governance.
Nansen, a blockchain analytics firm, played a crucial role in supporting the review process. Linea extended its appreciation for their contribution in helping maintain a fair and transparent ecosystem.
Sybil Attacks: A Growing Threat to the Crypto Industry
The recent Sybil appeal review in the Linea ecosystem highlights a broader challenge facing the cryptocurrency industry – the rise of Sybil attacks.
As token prices surge and airdrop events become more profitable, blockchain networks are increasingly targeted by fraudulent actors creating multiple fake accounts to manipulate rewards.
One of the biggest risks posed by Sybil attackers is their impact on airdrop events – where projects distribute free tokens to reward early adopters or active participants. Instead of genuine users benefiting, bots and Sybil accounts claim a disproportionate share, leaving real community members with fewer rewards.
As Linea prepares to launch its token with an airdrop in Q1 2025, the project is intensifying its security efforts to safeguard its ecosystem against Sybil attacks and fraudulent activities. While an exact date has yet to be announced, the token release is expected to be a major milestone for Linea, potentially drawing significant interest from the crypto community.
Sybil Attack on Starknet Airdrop
Other blockchains and protocols have already struggled against organized Sybil networks, with some suffering major breaches despite having strict anti-Sybil measures in place.
One of the most notorious Sybil attacks last year targeted the Starknet (STRK) ecosystem, exposing vulnerabilities in even the most well-guarded airdrop processes. In what became one of the largest Sybil exploits in the crypto space, an attacker used 1,361 wallets to fraudulently claim and consolidate 1,432,800 STRK tokens, worth approximately $3 million, into a single wallet, “0x027c…9078.”
starknet has allocated tokens to almost 150k devs on github. but some like our own @wavey0x got unlucky because they had renamed an account only to find the old name was squatted mere hours ago.

What made this breach particularly alarming was that Starknet had already implemented advanced Sybil protection mechanisms. Despite these safeguards, the attacker circumvented the standard one-wallet-one-claim rule, systematically gathering tokens across multiple wallets before funneling them into a single address.
