### What is Quai Network (QUAI)?
Quai Network (QUAI) is a decentralised Proof-of-Work blockchain protocol designed to deliver high scalability without compromising security or decentralisation. Built around a multi-chain architecture, Quai achieves parallel processing across multiple sub-chains, allowing it to reach transaction speeds that rival traditional payment systems while maintaining the robustness of a permissionless network.

At the core of its design is a dual-token system: **QUAI**, a deflationary asset used for governance, staking, and long-term value storage; and **Qi**, a stable digital currency designed for everyday transactions, pegged to real-world energy costs. Together, they form a balanced economic model — QUAI functions as digital gold, while Qi acts as a stable, energy-anchored medium of exchange.

### How does Quai Network work?
Quai introduces a unique, multi-layered chain structure composed of **Prime**, **Region**, and **Zone** chains that operate concurrently to achieve massive throughput. This hierarchical architecture allows independent block production while maintaining global consensus, supporting over **50,000 transactions per second** across the network.

The protocol uses a novel **Proof-of-Entropy-Minima (PoEM)** consensus mechanism, which selects the block with the lowest entropy rather than relying solely on computational power. This enhances energy efficiency, prevents chain splits, and strengthens network security.

Key architectural features include:
- **EVM-compatible smart contracts** — enabling developers to easily deploy existing Ethereum-based applications.  
- **Merge-mining** — allowing miners to contribute to multiple sub-chains simultaneously for enhanced security.  
- **Cross-chain interoperability** — enabling seamless transfers and conversions between QUAI and Qi.  
- **Layered scalability** — where each Zone and Region processes transactions independently, ensuring linear scalability as the network grows.

### What are the potential use cases for Quai Network?
Quai’s design supports both consumer-level transactions and enterprise-grade blockchain applications, including:
- **Global payments and remittances** — Qi provides a stable, low-cost currency for borderless transactions.  
- **Smart contracts and DeFi** — QUAI powers decentralised finance platforms and automated applications built on EVM infrastructure.  
- **Energy-linked digital assets** — the Qi stablecoin’s energy peg allows integration with renewable-energy markets and carbon-credit systems.  
- **AI and machine-to-machine payments** — Quai’s speed and stability support high-frequency microtransactions for the emerging AI economy.  
- **Enterprise blockchain solutions** — with its scalable architecture, Quai offers private and hybrid implementations for institutions requiring high throughput.
