Design After Nansen's Sybil Filtering Report

Congratulations to Nansen and Linea on the new sybil report. However, as they have noted, the filtering process was applied using a somewhat ‘lenient’ model, allowing up to 20 wallets per user. This once again highlights the importance of

Tiered, Hybrid

model.

According to the latest data, 780,243 wallets are eligible for the airdrop, with a two-week appeal period. Assuming a 4-5% approval rate for appeals, this number is likely to rise to around 800,000 wallets.


Found this data on X thanks to 0xBeggar

Data shows that the wallets between 500-2,000 LXP have sybil ratio up to %50

and this is only the ones thats flagged by Nansen.

Here is an example of a sybil wallet I discovered through my research on Lineascan, along with 22 wallets it funded. On average, each wallet earned approximately 4,500 LXP. Based on my observations, I believe most sybil/multi wallets fall within the 1,000-4,500 LXP range. Upon further analysis of this wallet, it’s clear that the owner is quite AMATEUR in their approach.

Due to the ‘lenient’ filtering applied by Nansen, there are still sybil/multi wallets among us, and they will inevitably affect the average rewards per wallet.

:stop_sign::stop_sign:As for those with more than 40 wallets that haven’t been flagged yet, a simple search on Twitter will lead you to them. Many are openly boasting about their actions and even sharing screenshots of their POH status for multiple wallets.

Additionally, what we know is:

Double LXP transfer affecting 2005 wallets

Browser extension HACK affecting between 19,600-33,800 wallets that holds LXP

Note:

This browser extension is used to farm airdrops with multi-accounts. I’m not sure how much sympathy the wallet holders deserve, but the amount of $Linea that may end up in the hands of hackers is significant and should be taken into account.

What should team do ?

  • First, the updated data needs to be shared publicly.
  • To simplify the calculation and distribution process, a new token could be issued (LXP2.0/FLXP) and transferred to non-Sybil wallets instead of LXP. However, before doing this, all questions in people’s minds need to be addressed, and the process should be carried out together with the community.
    • Corporate Sybil elimination might be finished, but I don’t think the community would be happy with allowing 20 wallets per user. Therefore, KYC / CEX claim / Multi-account filtering is necessary. (It might seem difficult, but if Metamask Card’s global access is ready by TGE, making MM Card a direct requirement could be a great solution, as it requires KYC and in the scenario where multi-accounts are filtered out, starting with 400-500,000 MM Card users would also have significant advantages. This would be a better solution than providing KYC to other institutions, firms, or CEXs.)
    • Checking with the existing Sybil Lists like Layerzero and others could be useful.

If No new filtering measures or KYC-like precautions are taken for Sybils and Multi-accounts,

then the reward difference between a wallet with the minimum LXP and a wallet with above-average LXP should be 20-25 times instead of the 10-12 times to keep it fair.

  • Minimum Criteria: A minimum of 1,500 LXP

2. Bonus Criteria Ideas

This section rewards wallets that meet specific activity-based criteria:

  • Ownership of both ENS and Linea-ENS.
  • Pre-Dencun Activity: At least 30+ transactions before the Dencun upgrade.
  • Wallet activity metrics:
    • Wallet age
    • Main Bridge
    • Volume
    • Active months (6-12 months)
    • Contract creation
  • Attestation of Digital Sovereignty AND ConsenSys Shanghai/Regenesis NFTs
  • Linea Mirror NFTs: 10 pieces — 20 pieces — 30 pieces
  • IRL event participation NFTs: 1 piece — 2 pieces — 3 pieces
  • veTOKEN voting count: 10 votes — 20 votes — 30 votes
  • Private Testnet participants (as most were dissatisfied with the 100 LXP reward)
  • Node Operators with >3 months of continuous uptime
  • Metamask Card
  • Top %0.5 LXP Holders
  • Surge 6 Volt Lp providers ( >0.1 eth)

LXP-L

*Top 100 wallets can be vested
*Reward reduction for Short Time - Whales

Community Rewards (NFT-Meme)

Given their history, contributions, volume, innovation and impact on Linea, an allocation reward should be provided to these community members from a separate pool in proportion to these factors.



Although these investigations may seem meaningless to some, I want to emphasize how crucial a

Fair Distribution

is on behalf of those who have been dedicated to Linea and have contributed to the network’s growth and the formation of its community over the past two years.

As the data shows, the Sybil/Multi-account ratio among the Top LXP holders is almost negligible, and I am confident that these wallet owners have been active across all aspects of the Linea ecosystem with only 1-2 wallets.

For this reason, we need a Tier and Hybrid-based distribution model.

Looking forward for your thoughts on this

I really liked it. There’s not much time left. Linea will do the right thing.

Everyone who posts ideas regarding the criteria is more or less biased.

MM card - although I am qualified for one I felt like my anonymity will be affected (I am probably not the only one with those concerns) and did not proceed getting it.

I have been LP-ing, Trading and interacting with Linea for more than one year but did not complete all the Quest for LXP and ,hence my LXP is under 1k. Acccording to your idea I should not qualify for $Linea because I did not complete anough Quest.
How is that fair ?

( I do agree for checking the socials for Account who brag about airdrop farming)

It’s fair, if only because it was mentioned in almost every AMA and community call that LXP is the foundation and a metric in the style of Proof of Work. All active participants in the ecosystem were aware of this information, and if someone ignored it, it’s primarily their own responsibility.

It’s absolutely fair to reward engaged users and base decisions on involvement.

It’s obviously shortsighted to reward users who farmed classic airdrop hunter criteria without considering what the ecosystem thrives on and what is important in it at the current moment.

Right.
My point is that simply counting the completed quests is quite narrow minded.

If MM Card will be live globally before TGE it should be the main criteria for rewards.
Because it have built-in KYC this way you can filter out sybils + large multi accounts

FYI i live in Türkiye and its not live yet

well if MM card is required in order to qualify - I am out… and if I am not the only one Better for the big LXP holders( yayy).
I am not willing to reveal my non-custodial wallet to the tax man.( I will report gains only when they are in my fiat bank account).

  • Indirect Traceability: Even though MetaMask Card doesn’t report directly, the blockchain’s transparency means transactions are publicly visible. “The Tax man” uses various tools and data matching to identify unreported gains or income from crypto transactions, potentially including those made via services like the MetaMask Card.

Great summary. I love data-driven posts.

I love it. I don’t really appreciate the MM card criteria because it is not available in my country and I think it won’t be available for the next 5-6 months. You said you are from Turkey and there is no card there yet, but we all know that it could be the next region added for the MM card accroding to team’s tweets on Twitter. So the chances of you being able to create a card and me are completely unequal. I can’t influence the situation, it is not in my power, which is sad to be taken as a criterion. This is not a way to popularize the card.

Secondly, I would reduce Dencun txns to like 5-10 since 30 is already priced in those wallets with high LXP balance which with implemented tiers will get sufficiently more than others and we all know that sybils don’t even have 1-3 transactions before Dencun.

I would totally eliminate

Since it appreciates sybil activity. These parameteres shouldn’t be considered at any way, all of them can be easily simulated and manipulated by old sybils with high LXP stacks.

Overall good topic, well done!

This has been discussed several times, this is exactly what sybils wants, the method has become popular since the time of arbitrum and zksynk. Totally a bad idea

There is only one fair metric: to evaluate contributions based on the actual amount of gas spent interacting with the network. LXP as a metric is completely unsuitable. Those with high LXP scores were simply farming LXP, which does not indicate that they are real users. Since the token launch is primarily about decentralization, it is necessary to distribute an equal number of tokens to all eligible network participants at the start. For those who deserve more than a certain amount of X tokens, a multi-year vesting period should be applied. @dfox @bigironchris

A good metric would be to revoke the entire remaining stack locked in multi-year vesting for anyone who sells their initial airdrop balance.

love to see we have similar vision my friend

My Proposal Focuses on Two Key Options:

1. New Sybil Filtering and Detecting Exaggerated Multi-Accounts Using KYC

The idea here is straightforward: if the MetaMask Card becomes globally accessible to everyone before TGE, the built-in KYC system can automatically filter out most multi-accounts and sybils effectively. This approach not only solves a major problem for Linea but also significantly boosts the adoption of the MetaMask Card, potentially bringing in hundreds of thousands of new users.

2. If No Sybil Filtering or KYC Will Be Applied

In this scenario, fairness must be ensured by designing a strict tier system with clear rules and bonuses. This alternative should involve:

  • Rigid Requirements: Clearly defined thresholds for eligibility, such as wallet activity, transaction volume, and LXP ownership.
  • Tiered Approach: Allocate rewards in proportion to user contribution levels, ensuring a significant gap between the rewards for low and high contributors to discourage multi-account farming.
  • Bonuses: Additional rewards for wallets with notable achievements or long-standing engagement in the ecosystem.

Both approaches prioritize fairness and aim to reinforce the integrity of the Linea community while driving adoption and trust in the network.

Thank you! The tax man point is missing on my post and i realized with your reply.

We are here to disscuss and evolve

maybe the team can get the kyc with MM Card and we can have an option to bind 3 to 5 wallets (with lxp) per MM Card to claim the rewards to.

That way you can claim the rewards to a fresh wallet + for the ones that farming it with understandable amounts of wallet can get rewards too

Just to be clear i have only 1 wallet

sybils easily buy KYC on the market and will only be happy with this approach

this is clearly not feasible because Metamask is not supported in many counties and it will take time to be available to everyone.
option 2 is likely the solution

Some really good and some less good thoughts in there.
KYC is a bad idea, better try to minimize wallets per person / increase cost reasonably, for instance demand higher gitcoin score.
I do not think Linea is ready to manually do the L0 kind of work.
Best is to focus on multi-chain activity, mainnet txs over months, other drops eligibility, etc.
In a sense, I like your 2nd part more than the 1st. Better focus on giving more token for organic use! Months, apps, # of txs, etc. If smbd only farmed LXP and LXP-L on 100 wallets and didnt get filtered he should at least get much less token per wallet than smbd with 1 wallet who used the chain organically.
So, in essense, # of txs, gas spent (before Duncan especially), # of apps tried, turnover. This is what matters the most, not the LXP and the LXP-L!!!
