# Block Explorer

Block explorers provide valuable insights into the network's ledger, which records accounts, the tokens assigned to them, transactions between those accounts, and the creation of new tokens. As users engage in various activities on the network, changes occur within these accounts and tokens. A block explorer serves as an interface that allows you to access and examine this information in detail, offering transparency into the blockchain's operations. 

A block explorer is available for the [KUB Mainnet](https://www.kubscan.com/). This block explorer provides tools to help you debug smart contracts and transactions:

* View, verify, and interact with smart contract source code
* View detailed transaction information

A testnet explorer for [KUB Testnet](https://testnet.kubscan.com/) is also available.

## 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://docs.kubchain.com/tools/block-explorer.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.
