As users become increasingly active across different blockchains, a single on-chain identity can no longer keep up with the pace. A multi-chain identity system needs to maintain the independence and fairness of each ecosystem while also crossing network boundaries. So the question is: how can we build an identity scoring system that is both universally applicable across the entire network and does not disrupt the balance of each chain's ecosystem?

The core answer is actually simple—each chain should have its own scoring.

Why design it this way? The reason is that user behavior patterns on different chains are completely different. For example, activity levels, trading habits, and contract interaction frequencies on Ethereum are significantly different from those on Solana, Polygon, or other public chains. If we try to measure all chains with a single unified score, it will lead to unfairness—some chains' users may be underestimated, while others' activity levels may be exaggerated.

Maintaining independent scoring systems for each network allows users to receive fair evaluations within their own ecosystems without losing credit when transferring across chains. This is the correct way to build an identity system in the multi-chain era.
