# Architecture

Hashman uses a desired state-based system instead of direct commands. Think of it as setting a destination rather than giving turn-by-turn directions.

* **Desired state operations**
  * You set the target state (what you want)
  * System continuously converges toward desired state
  * No need to manually sequence commands
  * System fixes itself when issues occur

### Control loop architecture

### Key benefits

1. **Reliability**
   * System always trends toward desired state
   * Self-correcting on failures
   * Handles network issues and hiccups
   * Automatic recovery from ASIC errors
2. **Simplicity**
   * No complex command chaining
   * See what's happening
   * Quick problem diagnosis
   * Fewer human operator errors
3. **Scalability**

   * Scales with fleet exansion
   * Consistent behavior across fleet
   * Works anywhere <br>

   Unlike traditional tools that need step-by-step instructions, Hashman automatically figures out how to reach your desired state and optimizes towards it.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hashman.gitbook.io/hashman-docs/architecture.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
