In the digital age, the concept of identification is undergoing a tremendous transformation. In the past, a work badge could prove a person's identity and status, but in today's Web3 world, this traditional notion has become outdated.

With the development of blockchain technology, a new identification verification system is emerging - Lagrange's ZK ID. This system not only proves the authenticity of users but also comprehensively displays user behavior data across multiple blockchains without exposing the users' real identities.

The core advantage of ZK ID is that it can prove that users are real participants rather than automated scripts. It can display users' activity history across multiple blockchain platforms, including participation in DAO governance, long-term holding of liquidity pools, and using decentralized physical infrastructure networks (DePIN), among others. These actions constitute the user's "credit record" in the Web3 world.

As the creator of this on-chain ID system, Lagrange's main function is to integrate user activities across different wallet addresses into an anonymous yet trustworthy identification. Through zero-knowledge proof technology, it can demonstrate the user's credibility while protecting their privacy.

The application scope of ZK ID is quite broad. It can be used to generate zero-knowledge proofs of behavior, activate on-chain identification models, unlock AI agent usage permissions, access on-chain reputation systems, gain airdrop priority, and participate in DAO voting governance.

In short, Lagrange's ZK ID system can be seen as a combination of a digital passport, credit assessment engine, and entitlement certificate for users in the Web3 world. It represents a new generation of identification methods that will play an increasingly important role in the future digital economy.

With the continuous development of Web3 technology, we can foresee that innovative identification systems like Lagrange will become an indispensable infrastructure in the digital world, providing users with safer and more convenient digital identification verification services.
