On the evening of September 26, Celestia, the leading project on the modular track, suddenly announced that it would launch a genesis airdrop and distribute a total of 60 million TIA tokens (accounting for 6% of the total token supply) to the community.

This Celestia airdrop is quite generous. In addition to airdrops to early participants in the modular ecosystem, it also includes public affairs developers and researchers, Rollups early users, IBC relay node operators, Cosmos staking users, etc. Groups are also included in the airdrop scope.

However, while the sun is shining, Celestia is also working hard to avoid the increasingly rampant witch behavior through a variety of measures. Specific measures include directly adopting the witch address blacklist from the airdrop of Hop Protocol and Optimism, and using Trusta Labs witch screening mechanism analyzes specific addresses to determine whether they are suspected of witch behavior.

How exactly does Trusta Labs do airdrop detection? Next, let’s find out.

In August this year, Trusta Labs published a document detailing its on-chain behavior scoring standard, MEDIA Score. MEDIA Score has two functions. First, it provides the project party with an objective, fair, and quantifiable indicator to comprehensively evaluate the participation and value level of the user address, thereby accurately locating those users who have truly contributed to the project; second, Help users have a clearer grasp of their own address behavior, evaluate their chances of receiving potential community rewards (i.e. airdrops), and thus conduct on-chain interactions more reasonably and efficiently.

Judging from the specific scoring standards, the five letters M, E, D, I, and A in the MEDIA Score represent five dimensions respectively - currency (Monetary), participation (Engagement), diversity (Diversity), and identity ( Identity) and age (Age). The total score for the five dimensions ranges from 0 to 100, but the corresponding weightings vary.

M: Monetary

The Currency dimension is designed to assess the financial value of a specific address. Trusta Labs will uniformly convert the token balance in the address and the recorded amounts that have been interacted with into dollar-denominated values, and conduct comparative analysis with other addresses. The money dimension accounts for 25% of the weighted weight of the total score.

From the perspective of inspection content, the currency dimension will focus on inspecting three records:

1. Address balance: the total value of all tokens in the address;

2. Total interaction amount: that is, the accumulated amount that has been interacted with all protocols;

3. Official bridge amount: that is, the total amount of cross-chain transactions through the official bridge.

E: Engagement

The participation dimension aims to evaluate whether a specific address is deeply involved in the interaction of the on-chain ecosystem. This dimension not only requires users to have multiple interactions, but also requires that their interactions cannot be concentrated in a single time period. The participation dimension accounts for 30% of the weighted weight of the total score.

In terms of inspection content, the participation dimension will focus on inspecting five records:

1. Active days: At least 1 active interaction within a calendar day is counted as 1 active day;

2. Number of active weeks: At least 1 active interaction within a calendar week is counted as 1 active week;

3. Number of active months: At least 1 active interaction within a calendar month is counted as 1 active month;

4. Total number of interactions: that is, the total number of interactions with all projects on the chain;

5. Interaction time span: The time span from the first interaction to the most recent interaction.

D: Diversity

The Diversity dimension aims to assess the breadth of items (contracts, protocols, categories) that a specific address interacts with. The diversity dimension accounts for 15% of the weighted weight of the total score.

In terms of inspection content, the “diversity” dimension will focus on inspecting three records:

1. Number of interactive contracts: the number of independent contracts that have been interacted;

2. Number of interactive protocols: the number of independent protocols that have interacted;

3. Number of interactive protocol categories: The number of interacted protocol categories (DeFi, NFT, Web3 Game, Infra, etc.).

I: Identity

The Identity dimension aims to evaluate the specific identity role and qualifications of a specific address in the L1/L2 ecosystem. The identity dimension accounts for 10% of the weighted proportion of the total score.

From the inspection content, the identity dimension will focus on checking the following records:

1. Multi-signature membership: For example, as a member of a well-known DAO;

2. Specific NFT holders: such as NFT officially issued by zkSync;

3. Historical airdrop targets: such as Arbitrum airdrop users, or Optimism airdrop users;

4. DID holders: For example, holding ENS.

A: Age

The Age dimension is designed to assess how long a specific address has been involved in a specific project. Generally speaking, early users are more valuable to the cold start of the project. These users can grow with the project and show higher loyalty. The age dimension accounts for 20% of the weighted proportion of the total score.

From the inspection content, the age dimension will focus on checking the following records:

1. Bridge age: the length of time since the address was first bridged;

2. Interaction age: the length of time since the address first interacted with the user.

Total score calculation method:

Regarding the on-chain performance of a specific address within five dimensions, Trusta Labs will give a sub-score ranging from 0-100 to facilitate users to understand the performance of their addresses in different dimensions.

However, when calculating overall performance, the sub-scores within each dimension are calculated based on the weighted proportions of different dimensions, and a total score ranging from 0-100 is finally obtained.

Taking the analysis of a certain zkSync Era address in the above figure as an example, the scores of this address on M, E, D, I, and A are 41, 83, 93, 20, and 66 respectively. It can be seen that the address’s breadth and scope of interactive projects It performs well in terms of times, but has shortcomings in terms of on-chain identity and other aspects.

Trusta Labs compared the addresss total score of 64 with all zkSync Era user addresses and concluded that the addresss total score ranked in the top 26%. However, this cannot be used as a basis for whether the address can receive the potential airdrop of zkSync Era, because the final right to draw the score line is still in the hands of the project team. For example, the standard adopted by Celestia for early Rollups users this time is the top 50 %.

summary:

Considering Celestia’s leading position in the industry, there is a possibility that its airdrop design will be adopted by other unreleased currency projects in the future. In addition, Trusta Labs has directly provided the two most popular unreleased coins such as zkSync Era and Starknet. Therefore, it can be expected that MEDIA Score will have a huge impact on the entire airdrop market in the future.

For studios that have an absolute advantage in the number of addresses, the emergence and promotion of MEDIA Score is obviously not good news. Balance, DID, age, and other check contents will inevitably increase the studio’s operating costs. In an era of shrinking production, this may create new financial challenges for studios, especially newer, smaller organizations.

However, for more real users (of course it is difficult to avoid wooly people who operate boutique accounts), this is a good opportunity for them to defeat the scientists in a corner. After all, considering that popular projects now easily cost millions The total number of interactive addresses, if more stringent screening is not carried out, the airdrop income available to real users will most likely be diluted into mosquito legs.

For the project side, the game between it and the witches may also usher in some changes. Before this, most of the games between project parties and witches were conducted head-on. The project parties needed to select airdrop targets on their own based on user interaction portraits, such as Hop, Optimism, Paraswap, etc.; now, with Trusta Labs, Gitcoin Passport, etc. With the emergence of the third-party witch screening mechanism, project parties can hand over this part of the work to a third party with less effort, thereby focusing on their own business.
