# What is Earth LinC

Earth LinC began as a question, not a product: **can action for this earth carry permanent, sovereign value of its own?**

Earth LinC is an open protocol — owned by no one, initiated and anchored by YuCROWN, built on by anyone. It exists for one new behavior: something you do for this earth, given **permanent, sovereign form on-chain**. Not a post that scrolls away. Not a row in someone's database. A thing that is *kept* — owned by you, connected to people, anchored to a real place.

## How it works, in one breath

You bring an activity — anything you do, or want to do, for this earth. AI gives it a living form: a **station**. You can share it openly and freely. When you're ready, you **mint** it — your station takes its permanent on-chain form, and you choose what it carries: a real **mission** for the earth, or nothing but itself. Then, from your minted station, you **Cast**: a **NaviStar** to a person you choose — a permanent, two-way link between you, kept in their **Realm**.

## The acts

Everything on Earth LinC is one of three moves:

* **Broadcast** — share your station, open and free. Off-chain; everyone can play.
* **mint** — anchor your station on-chain, carrying a mission or plain. *The mint anchors.*
* **Cast** — a NaviStar, minted from your station to a person you choose. *The Cast connects.*

What's Cast to you, you **keep** — in your **Realm**, your own sky. No likes. No comments. No counts. To respond is to Cast back.

## Where it lives

On-chain — on a public network, under open standards. What you mint, what you Cast, and what you receive is sovereignly yours: it doesn't depend on any company's account system, and it would remain even if every company building here disappeared. That is what makes Earth LinC a protocol, not a platform.

**What you do for the earth becomes part of who you are.**

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://earthlinc.gitbook.io/protocol/start/what-is-earth-linc.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.
