# Blockchain networks

Blockchain options:

* **Internet Computer** – non-EVM Layer 1 blockchain enabling fully on-chain applications with Web2-like UX. Offers fast, low-cost transactions. Build web3 social media, games, DeFi, secure front-ends, ledgers, enterprise apps, and AI models, [read more](https://internetcomputer.org/)
* **Polygon** – scalable and low-cost EVM-compatible network built on top of Ethereum. Ideal for fast and low-cost apps used by many users, [read more](https://polygon.technology/)
* **Ethereum Mainnet** – you get access to global public Ethereum network using PoS, [read more](https://ethereum.org/en/enterprise/#private-vs-public)
* **SparkNet** - private Ethereum based network, used for pilot and productive solutions mainly, [read more](https://sparknet.online/)
* **DevilNet** - private Ethereum based network run by CoreLedger, used for development purposes mainly
* Your option can be discussed upon a request

# Agent Instructions
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://teos-docs.coreledger.net/resources/using-the-teos-api/architecture-note/blockchain-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.
