# 2.1 Modular Blockchain Architecture

Luluchain is built on the Cosmos SDK, leveraging Cosmos' modular blockchain architecture to flexibly construct and integrate diverse functional modules. In Luluchain, the emotional analysis module, social interaction module, gaming ecosystem module, and DeFi functionality module each operate independently but are interconnected through underlying protocols. This modular design allows developers to customize development according to their needs while ensuring synergy between different modules.

1. **Scalability**: By separating the consensus, execution, and data availability layers, we can enhance the system's scalability to meet the demands of user growth.
2. **Flexibility**: The modular architecture supports rapid iteration and upgrades of different functional modules, ensuring the system's innovation and cutting-edge nature.
3. **Interoperability**: The modular architecture enables seamless integration of different applications into the Luluchain ecosystem, supporting cross-chain interactions.
