# High-Performance Blockchain Layer

CubiC is supported by a **modular Layer 1 blockchain architecture** purpose-built for large-scale commercial applications. This layer acts as the foundational infrastructure that enables high-frequency trading, data processing, and secure transaction settlement.

#### Key Capabilities

* **Ultra-high throughput (near-unlimited TPS)**, allowing the system to handle massive volumes of transactions without congestion
* **Parallel transaction execution**, enabling simultaneous processing of multiple operations for improved efficiency
* **Real-time global settlement**, ensuring transactions are confirmed and finalized with minimal delay
* **Modular architecture (Mainnet + Hub + AppChains)**, providing flexibility in deployment and system design
