Linea Removes 516,960 Sybil Addresses Ahead of Token Airdrop

Highlights:

• Linea removed 516,960 Sybil addresses, reducing eligible wallets from 1.3 million to 780,243.
• Linea partnered with Nansen to analyze on-chain data and block fraudulent wallet behavior.
• Users flagged as Sybil can appeal decisions through a dedicated portal for fairness.

Linea, a Layer 2 Ethereum network, updated its token event airdrop eligibility requirements. It teamed up with Nansen to identify and delete possible Sybil addresses from 1,297,203 wallets. The analysis monitored LXP token distributions and on-chain actions. This step aims for a fair distribution and supports the network’s transparency pledge.

Linea detected that 516,960 addresses were part of orchestrated or automated operations. The team decided not to include these wallets in upcoming token distributions. Currently, 780,243 addresses qualify for eligibility. The platform allows flagged users to submit appeals through a dedicated portal.

Officials explain that this process follows their previous method of authenticating people’s identities using Proof of Humanity. They have set higher limits to spot large-scale farming operations. They tolerated smaller multiple-wallet use. The system aims to distinguish real users from major farming groups by making as few mistakes as possible.

LXP assigned tokens to users who bridged networks and used decentralized applications. Officials say validating authentic user participation helps build network reliability. The updated list effectively serves dedicated participants as well as trustworthy community users. This system is designed to reward users who truly participate.

Key Findings from the Sybil Detection

Nansen’s expertise helped the team find groups of suspicious addresses. The team checked how wallets interacted over time and searched for common usage patterns. The data-driven process revealed multiple wallets that showed synchronized activity patterns. The data grouped multiple similar Sybil addresses as a possible sign of one individual controlling them.

The team established strict similarity requirements for analysis. The method protected users who handle multiple wallets from receiving penalties. The officials focused on user groups that operated more than 20 connected addresses. The team chose precise detection methods to protect valid users with minimal on-chain overlap. 

Analysts performed manual checks after the automated analysis. Experts selected random clusters to verify their coordinated activity. In addition, they prevented false detections by directly comparing each group’s activity. The completed selection effectively detects all users without leaving out authentic participants.

Linea allows users flagged in their system to challenge the decision if they think it’s incorrect. Users have a two-week window to submit their appeal form on the website. The process works to find errors that the detection system could overlook. Officials stress that detailed verification protects the airdrop program against large-scale farming operations.

Future Steps for the Token Distribution

Linea plans its token-generation event in the first quarter of 2025. This rollout includes a community airdrop under revised eligibility rules. The token aims to decentralize zkEVM infrastructure and foster broader community participation. Moreover, it supports governance decisions within the Layer 2 ecosystem.

The protocol’s nonprofit governance arm, Linea Association, oversees technology development and market growth. It was formed in November last year to shape the network’s roadmap. Officials say its framework guides open-source release decisions. Consequently, the token distribution will align with that mission.

Today we reach a major milestone: Introducing the Linea Association, an independent Swiss non-profit dedicated to advancing our ecosystem's development and governance. This marks a significant step toward true network decentralization.

Users can expect updates on token design and allocation metrics. Linea developers say the snapshot for final distributions is pending. Hence, each user’s on-chain activity may influence grants. Meanwhile, the team focuses on trust through transparent steps reflecting genuine network engagement, free from Sybil addresses.

Details on token economics remain under wraps. Moreover, the timeline for permissionless access depends on extended stability tests. The network aims to expand decentralized features over time. This phase follows the mainnet launch in July 2023, when Linea introduced its zkEVM solution.

Important update for the Linea community! We've partnered with @nansen_ai to conduct an additional sybil analysis on LXP holders. Here's what you need to know:https://t.co/aaivZIN2oy
