# IncreaseDeclarationSpace

This is the interface for storage miners to increase the size of declaration space. The declared space size corresponds to your staking. Once your staking does not meet the declared space size, you will enter a frozen state.

```golang
// IncreaseDeclarationSpace increases the size of space declared on the chain
//   - tibCount: the size of the declaration space increased, in TiB
//
// Return:
//   - string: block hash
//   - error: error message
//
// Note:
//   - the size of the declared space cannot be reduced
//   - when the staking does not meet the declared space size, you will be frozen
func (c *ChainClient) IncreaseDeclarationSpace(tibCount uint32) (string, error)
```

For example code, please refer to [increase.go](https://github.com/CESSProject/cess-miner/blob/main/cmd/console/increase.go)

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://doc.cess.network/developer/cess-sdk/sdk-golang/chain_related/sminer/increasedeclarationspace.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.
