# Optimism

Optimism is a second—level solution (Layer2, L2), which is designed to increase the speed and scalability of the Ethereum network.

The Optimism blockchain uses the Optimistic Rollups technology, which reduces the cost of transaction fees tenfold compared to the first level (L1) of the Ethereum network and at the same time makes it easy to deploy any smart contracts and decentralized applications written in the Solidity language in the second level network.

All CryptoDo modules and smart contracts are available for deployment on the Optimism network.

## 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.cryptodo.app/blockchains/optimism.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.
