# Networks

COTI test networks provide developers access to a free testing environment for COTI v2 network services. Testnets simulate the exact development environment as you would expect for Mainnet. This includes transaction fees, available services, etc.

#### Network Technical Details

When utilizing the COTI network environments, it is vital to understand the technical details that influence their operation. Here are some key parameters you will encounter:

* **Base Gas Fee**: The base gas fee is set at 5,000,000 wei. This fee is fundamental for executing transactions on the network and is essential for interacting with smart contracts effectively.
* **Block Gas Limit**: Each block has a gas limit of 120,000,000. This limit dictates the total amount of gas that can be used for all transactions within a single block, ensuring that blocks stay within a manageable size for processing.
* **Block Generation Time**: Blocks are generated every 5 seconds. This rapid block generation contributes to the network's efficiency and ensures that transactions are processed swiftly, providing developers and users with timely updates.

Understanding these parameters is crucial for developers and users interacting with the COTI environments, as they directly impact transaction execution and network performance.

## 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.coti.io/coti-documentation/networks.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.
