# Polygon

Polygon (formerly known as Matic) is a Layer 2 scaling solution built on top of the Ethereum blockchain. It is designed to provide faster and cheaper transactions than the Ethereum network, while maintaining the same level of security and decentralization.

One of the key features of Polygon is its use of sidechains, which are independent blockchains that are connected to the main Ethereum network. This allows for faster and cheaper transactions, as they can be processed off the main Ethereum chain. This is especially useful for applications that require high transaction throughput, such as decentralized finance (DeFi) and gaming.

Polygon also supports a variety of Layer 2 scaling solutions, including Plasma and Optimistic Rollups. These solutions allow for even greater scalability and reduce transaction fees even further, making it a more cost-effective option for developers.

Another advantage of Polygon is its support for smart contracts, which can be created using the popular programming language Solidity. This makes it easy for developers to build decentralized applications (dApps) that can leverage the benefits of the Polygon network, such as faster transaction times and lower fees.

In addition to its technical features, Polygon has a vibrant ecosystem of developers and projects building on its network. This includes a wide range of DeFi applications, NFT marketplaces, and gaming platforms, among others.

Overall, Polygon is a powerful scaling solution that provides developers with the tools they need to build fast, efficient, and cost-effective decentralized applications. Its support for sidechains, Layer 2 scaling solutions, and smart contracts makes it an attractive option for developers looking to leverage the benefits of the Ethereum network while avoiding the high costs and scalability issues associated with the main chain.

## 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.cryptum.io/english/cryptum/ecosystem/polygon.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.
