### How to Read This Whitepaper

This V3 whitepaper focuses on the core architecture of ForU AI and its role as the trust layer for the AI economy. It explains the problem of broken trust in the age of AI, the design of the ForU reputation infrastructure, and how the ecosystem connects identity, reputation, and economic opportunity.

The document is structured in three parts:

* **The Problem** – why trust and reputation systems are failing in the AI era
* **The Architecture** – the pillars of the ForU protocol and how they work together
* **The Economy and Execution** – market opportunity, token mechanics, and the development roadmap

Some previously introduced features, experiments, and early ecosystem concepts are documented in **Version 1 and Version 2** of the whitepaper. Those documents provide additional context and historical design decisions that are not repeated here.

Readers who want a deeper understanding of earlier components are encouraged to review the previous versions alongside this document.
