# Layer 2 (L2)

On Layer 2 networks, transaction fees will be drastically reduced by packing multiple off-chain transactions into a single L1 transaction, making it easier for everyone to participate in Ethereum. The L2 network blockchain settles transactions on the Ethereum mainnet, enabling users to benefit from the security of the Ethereum network. As transactions per second (TPS) increases, transaction fees decrease, and new technologies develop, new applications will emerge within the ecology and boost user experience. The Ethereum ecosystem stays steadfast in supporting L2 networks because L2 network scaling is the only way to solve the scalability trilemma while maintaining decentralization and security. Zecrey is an outstanding Layer 2 privacy protocol utilizing cutting-edge zk-Rollup technology.

## 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.zecrey.com/education/concepts-explained/crypto-knowledge/layer-2-l2.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.
