The Linea Case: How Anti-Sybil Filters Changed Airdrop Rules

The story of the airdrop that put an end to the era of “generous” tokens

Linea changed everything. It became the boundary between the era of generous drops and a new era of strict verification. When the long-awaited LINEA token airdrop launched in September 2025, the crypto community faced a new reality: rewards go only to real users, not reward hunters seeking easy money.

Linea is an additional layer built on top of the Ethereum blockchain platform (for creating and launching decentralized applications (dApps) and smart contracts). Ethereum’s main problem was that it became too popular and the network was being used by many people simultaneously. As a result, transactions slowed down and fees rose to $10-50 per operation. Linea offloads the network and processes transactions dozens of times faster and cheaper, but with the same security.

On September 10, 2025, the LINEA token launched on major exchanges. But the real excitement in the crypto industry wasn’t caused by the trading itself, but by the strict distribution system. The Linea team implemented powerful anti-Sybil filters that ruthlessly cut off “freebie” hunters with fake wallets. Tokens are received only by real ecosystem participants who conducted transactions and contributed to the project’s development.

The LINEA token rewards the active community, supports developers and projects within the ecosystem, and provides long-term funding for Ethereum’s development. This airdrop became the benchmark for a new era—a time when crypto projects stopped distributing tokens to everyone and started valuing quality of interaction over quantity of participants. Why? Let’s break down the Linea case.

How the Campaign Began

Users learned about Linea’s activity after an official announcement from the ConsenSys team behind MetaMask. When it became known that the project had raised over $600 million in investments, it immediately attracted community attention. Simultaneously, the team launched a testnet campaign, where anyone interested could test the network, interact with dApps, and gain experience working with a new scaling layer.

A large number of users joined precisely because of the combination of the strong MetaMask brand, significant investments, and a clear opportunity to participate at an early stage.

In 2023, there was a testing period for the project on its network. The team checked whether the network could withstand mass use of applications and partner projects. Linea chose the Galxe platform with proven experience in mass user engagement. Together they launched Linea Voyage—a public quest campaign on the test network, open to all Web3 enthusiasts and developers. The campaign was joined by 11 ecosystem partners and 50 applications. Over 5 weeks of thematic tasks, participants gained real experience working with the Linea network. As a result, the community actively engaged in testing (5.6 million unique wallets!), project recognition grew (50 million test transactions were conducted on Goerli), and the team received valuable feedback.

Linea Voyage Interact & Linea Park

The second stage was divided into 2 directions: NFT & GameFi and DeFi.

Linea Voyage Interact & Linea Park is an interactive virtual world where users didn’t just learn about Web3, but earned LXP tokens by interacting with real ecosystem projects. The main idea: make the crypto world accessible and exciting for everyone. From February 20, 2024, over 6 weeks, users completed tasks in a virtual world across 10 different zones. Each week, participants unlocked a new zone with unique challenges. By completing missions, users earned LXP points—an internal currency that could potentially be converted to tokens in the future.

Special attention went to NFTLand — a space dedicated to digital assets. Here participants interacted with NFT projects, connected social networks to blockchain, played Web3 games, and simply immersed themselves in NFT culture.

Linea Voyage XP are digital rewards in the format of Soulbound tokens (they cannot be sold or transferred). They are issued to participants as recognition of real contributions to the Linea ecosystem’s development. By completing tasks within Linea Wave—regular activities in the ecosystem— users could receive a certain amount of XP. Additional points could be earned through a separate series of Linea quizzes on the Intract platform.

The third stage — Linea Voyage

The Surge, was aimed at attracting liquidity providers to the ecosystem. It continued until the ecosystem’s cumulative TVL reached $3 billion (this campaign was planned for six months to collect $3 billion TVL, but the team failed to reach the planned mark). By providing liquidity, users could earn LXP-L points, which could potentially qualify them for a future drop. The program has only one type of activity: providing liquidity on various platforms in the Linea ecosystem.

The Linea Voyage (LXP) program had 7 distribution levels: the higher the user’s engagement, the more substantial the reward. Linea Surge (LXP-L) holders (liquidity providers) received amounts directly proportional to their contribution. Bonus rewards exist for early contributors, for key ecosystem participants for stable activity, and simply for active MetaMask wallet users.

The project introduced three 10% multipliers:

  1. For early users who actively tested and used Linea before the Ethereum Dencun upgrade.
  2. Rewards went to those who genuinely used Linea for at least six months, not just checking boxes in quests. This cultivates healthy behavior in the ecosystem.
  3. For active use of MetaMask products, rewards go to users, helping to further establish the Linea brand.

    85% of all tokens were directed toward ecosystem development:

    • 10% will go to early users and developers;
    • 75% goes into a 10-year ecosystem fund;
    • 4% will be allocated to liquidity providers through an airdrop.

    Zero allocation for the team and venture capital—a decision that radically distinguishes Linea from most crypto projects. The Linea consortium will control the fund’s assets, with participants from Consensys, Eigen Labs, ENS Domains, SharpLink Gaming, and Status.

    The reward distribution occurs from September 10, 2025 (Linea listing) to December 9, 2025. Unclaimed tokens return to the Linea ecosystem fund.

    Airdrop Economics: Expectations vs Reality

    In September 2024, over 9 billion LINEA tokens were distributed among more than 740,000 unique addresses.

    To receive the basic Linea airdrop, users needed to accumulate 1,500 LXP-L (internal system points). Actual participant costs:

    • Investment: ≈ $20 (transaction fees, dApp interactions)
    • Received: ≈ $75 (3,000 LINEA tokens)
    • Multiplier: 3.75x on invested funds

    Considering the scale of the Linea ecosystem, Consensys support, and the time users spent on network activity, many expected payouts comparable to Arbitrum, where the minimum drop was ≈ $700 (almost 10 times more). Instead, they received a conservative 3x on spent resources. The airdrop proved profitable, but not as generous as the community anticipated.

    To ensure tokens went to real people rather than armies of bots and farmers with hundreds of wallets, Linea implemented two-level protection: Proof-of-Humanity (PoH)—verification confirming that a real person stands behind an address. And it established minimum activity thresholds: 1,500 LXP—basic level and 15,000 LXP-L—advanced level.

    Sybil-Hunting: How Linea Cut Off Farmers

    Sybil” — a user who creates dozens or hundreds of accounts to increase chances of receiving rewards.

    Linea and ConsenSys conducted an unprecedented anti-Sybil operation, excluding over 516,000 addresses from the airdrop (40% of the initial list of 1.29 million wallets). With support from the analytics platform Nansen, the team used a comprehensive approach:

    • Analysis of transactional patterns to detect identical action sequences
    • IP address tracking to identify wallet clusters from a single device
    • Behavioral models: AI algorithms for clustering similar on-chain activity
    • Detection of specialized software for automating and coordinating actions between connected wallets (farms)
    • Application of large labels and data coverage for precise identification

    Results

    As a result, tokens were distributed among over 780,000 legitimate wallet owners. For many farmers who spent weeks creating hundreds of wallets, this became a financial blow. Suspicious accounts were either completely blocked or received significantly reduced payouts.

    Important information

    Linea changed the rules of the game. This story taught the entire Web3 community a harsh lesson: the era of "easy drops" is irreversibly over. The times when it was enough to create a dozen wallets and perform a couple of transactions are finished. But this doesn't mean opportunities have disappeared.

    After Linea, many lost faith in “fair retrodrops.” However, they simply became available to those who genuinely use products, invest time in understanding the ecosystem, and become part of the community rather than reward hunters. The new reality: quality of participation is more important than quantity of wallets. The industry awaits a new wave of projects that emphasize quality over quantity of activities and are preparing for drops (SandChain, Base, Abstract, Backpack).
