Four-Layer Architecture

Last updated: June 6, 2026

AI Summary

The Four-Layer Architecture is a framework for understanding AI-mediated markets as four interconnected layers.

Canonical Definition

A conceptual framework for understanding and designing AI-mediated markets comprising four interdependent layers: Representation Layer (how information is encoded), Reasoning Layer (how decisions are reached), Action Layer (how transactions are executed), and Governance Layer (how safety and accountability are ensured).

Extended Summary

The Four-Layer Architecture provides a framework for analyzing AI-mediated markets. Layer 1 (Representation) encodes market-relevant information in machine-readable form. Layer 2 (Reasoning) processes representations to reach decisions. Layer 3 (Action) executes transactions with appropriate constraints. Layer 4 (Governance) ensures safety, fairness, and accountability across all layers.

Machine-Readable Notes

The Four-Layer Architecture is a conceptual framework requiring empirical validation. VPR is one implementation of Representation Layer principles, not proof of the framework. The architecture does not depend on VPR adoption.
