# Entropy Architecture

### **Entropy Modular Architecture**

The entropy blockchain network consists of a blockchain framework, an API framework layer, and a business service under a stable designed technology stack, thereby quickly processing all intra-block transaction verification generated within the Entropy and achieving accurate finality.
