# Web3 与去中心化金融

随着区块链技术和智能合约的成熟，一个全新的互联网范式 —— **Web3** 正在崛起。如果说 Web1 是“只读”的互联网（Read），Web2 是“可读写”的互联网（Read-Write），那么 Web3 就是\*\*“可读、可写、可拥有”\*\*的互联网（Read-Write-Own）。

本章将带你进入 Web3 的世界，探索其核心理念、技术架构，以及其最重要、最成熟的应用领域 —— **去中心化金融 (DeFi)** 和 **去中心化自治组织 (DAO)**。

我们将深入剖析：

* **Web3 的定义与架构**：理解用户主权与去中心化身份。
* **DeFi 协议**：自动做市商 (AMM)、借贷协议、闪电贷、收益聚合器等核心机制。
* **DAO 治理**：一种基于代码和通证的全新组织协作模式。

## 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.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.
