# Overview

Tashi is the coordination layer for intelligent systems. While the world's digital infrastructure has matured across compute, storage, and connectivity, one primitive remains unsolved: the ability for independent systems to reach agreement in milliseconds without trusting a central authority.

Tashi solves this with real-time, leaderless edge consensus through a three-layer architecture:

* **Vertex**: Sub-100ms Byzantine fault-tolerant consensus at the edge
* **Lattice**: Global DePIN infrastructure for discovery, validation, and rewards
* **Arc**: Settlement bridge to public blockchains when needed

This architecture enables autonomous systems (robots, AI agents, IoT devices) to coordinate across trust boundaries without centralized control.
