# Welcome to Zentra

Zentra is the OS Layer of blockchain—a continuously evolving blockchain operating system layer. We are neither an L1 nor an L2; we run atop world computers and can swap to better ones like changing hardware. When faster, cheaper, or more decentralized world computers emerge, we can switch underneath the ecosystem with no user disruption and no need to rebuild.

Unlike traditional blockchain layers, Zentra's execution engine and ecosystem operate outside of blockchain nodes, leveraging Minus Theory to decouple consensus and execution. As an OS Layer we keep the ability to run in a decentralized way while partnering with more decentralized L1s over time. The iterating OS Layer makes the ecosystem portable to higher-TPS, lower-cost world computers and removes common constraints such as gas limits, enabling developers to ship richer applications with unprecedented ease.

## Roadmap

* **Testnets 1-3**: Completed for stability testing.
* **Mainnet Launch**: December 2025, with real funds and decentralized indexers.
* **TGE and Airdrop**: Pending; airdrop distributed after TGE.
* **Post-Launch**: Ecosystem growth, quantum upgrades as needed, continuous OS layer evolution.

# 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://zentra.gitbook.io/en/readme.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.
