What are Model-Based Stamps: Ethereum, NFT, and zkSync

Your Ethereum, NFT, and zkSync Stamps in the Passport XYZ use Model-Based Detection use supervised machine learning models to score you based on how similar your transaction history resembles Sybils.

1. What are Model-Based Stamps?

The Ethereum, NFT, and zkSync Stamps are not just a badge of participation but a nuanced indicator of genuine activity on Ethereum's mainnet (Layer 1), with NFTs on Ethereum mainnet, and on zkSync. If you did not receive points, it doesn't imply you're seen as a Sybil entity. Rather, it means the model requires more robust activity data to confidently assign points under the new system.

2. The Evolution of the Stamp

We're periodically refining these Stamps to more accurately reflect the vibrant dynamism of Ethereum transactions. While previous versions had merits, newer versions of the Stamps embraces a broader spectrum of engagements, ensuring a more inclusive and comprehensive representation of community involvement.

3. Transparency and Point Allocation

The specifics of the model's criteria are kept under wraps to maintain the integrity of the Stamp and prevent gaming the system. Rest assured, the model is designed to reward authentic, varied, and consistent participation on the network, and have been rated as the best-in-class Sybil detection model in the industry by third-party experts.

4. The 90-Day Validity Period

The 90-day renewal cycle ensures that the stamp remains a current and accurate portrayal of your latest activities. This regular update aligns with the fast-paced evolution of the Ethereum ecosystem and allows for adjustments that reflect your most recent contributions.

5. Deciphering Stamp Levels

The Model-based Stamps are divided into different groups of credentials. You'll notice that one section awards you based on how robust and human-looking your relevant transaction history appears, while others award you based on specific holdings.

7. How the Model-Based Stamp Operates

The Stamps are powered by a Passport XYZ-specific binary classification model, trained on a dataset of known Ethereum addresses with established Sybil and human activity patterns, utilizing dozens of different activity features, per model.

Conclusion

Your Model-Based Stamp dynamically evolves with your activity, serving as a credible beacon of your Ethereum involvement. It's a testament to your contributions and a guidepost for new ventures on the blockchain.
