# Use-Cases

CHAIN token use cases across the Zentachain ecosystem — staking, messaging, and node rewards.

## Zentanode

Zentanode is decentralized mining hardware for offline connectivity. Operators power the Zentamesh network and earn 25 CHAIN tokens per month. Zentanodes provide offline communication within a 6km range and serve as gateways for the Zentamesh network. The Zentanode reward program will begin once node operations launch.

## Zentamesh

The Zentamesh network is a decentralized mesh protocol powered by the CHAIN token. By owning a Zentanode and participating in the network, you earn CHAIN tokens while enabling offline communication for Zentalk users.

## Staking

Stake CHAIN tokens to participate in network governance and earn rewards. Multiple staking tiers are available with competitive APY rates and flexible lock-up periods.

## Zentalk

Zentalk is an end-to-end encrypted messenger on a decentralized mesh network. It uses Signal Protocol, 3-hop onion routing, zero-knowledge proofs, and post-quantum cryptography. No phone number required — sign in with a Web3 wallet.

Key features:

* Encrypted messaging, voice & video calls, groups, channels, stories
* Offline communication within 6km of a Zentanode
* Server-blind architecture — nodes cannot decrypt your data
* Web3 wallet login with multi-chain support
* Available now at [zentalk.chat](https://www.zentalk.chat/)

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zentachain.io/chain-network/use-cases.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
