# 本章小结

本章介绍了 Web3 的核心概念和去中心化金融（DeFi）生态：

* **Web3 架构**：从 Web1（只读）到 Web2（读写）再到 Web3（读写拥有）的演进，以及 Web3 的技术分层结构。
* **DeFi 协议**：包括 DEX（自动做市商）、借贷协议、稳定币和收益聚合器等核心应用。
* **DAO 治理**：去中心化自治组织的运作模式、类型和挑战。

Web3 代表了互联网发展的新范式，尝试把身份、资产和部分数据控制权从平台转移到用户手中。DeFi 则展示了可编程货币的组合能力，让部分金融服务更开放、透明和可组合。

Web3 和 DeFi 能否进入更广泛的主流应用阶段，取决于安全、用户体验、扩展性、隐私保护和监管框架能否继续改善。

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://yeasy.gitbook.io/blockchain_guide/12_web3/summary.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.
