# Technical Implementation Path ## Sub-chain 1: From Centralized to Decentralized * Centralized Data Collection + Centralized Tagging Model + Centralized Tagging Database * Provides data services ## Sub-chain 2: From L2 to L1 Sub-chain 2 will launch as a dedicated Ethereum Layer 2, independently operating the zkPassport protocol for identity management and credential verification. This Layer 2 fully relies on the Ethereum mainnet as the data availability and final settlement layer. As the network develops and its functionality expands, the zkPassport Layer will gradually evolve into a Layer 1 blockchain with independent consensus and data sovereignty, supporting a larger-scale Web3 identity ecosystem and compliance infrastructure. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
