# Celestia

## About

Celestia (TIA) is the first modular blockchain network that enables anyone to easily deploy their own blockchain with minimal overhead. Celestia scales by rethinking blockchain architecture from the ground up. It is a minimal blockchain that decouples execution from consensus by introducing a new primitive, data availability sampling. Since Celestia does not impose any execution or settlement constraints, developers are free to define their own execution and settlement environments. This unlocks new, unrealized possibilities for builders and developers.

Celestia is a departure from the status quo of monolithic blockchains. Monolithic blockchains face scaling difficulties because they perform all core functions of a blockchain such as processing transactions, ensuring that transactions are correct, and getting network nodes to agree on both the validity and ordering of transactions. Modular blockchains introduced the notion of decoupling consensus from the execution of transactions, thus achieving greater scalability without loss of security or decentralisation.

A modular approach to blockchains opens up a world of new possibilities. Experimentation becomes much easier as new application specific or general purpose blockchains can deploy to Celestia and immediately inherit security from Celestia’s validator set. Modular blockchains enable control over the rules of an application through sovereignty because developers can make alterations to the tech stack without permission from outside applications.

## 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://service.block-pro.net/mainnet/celestia.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.
