# 为什么要拥有 .bnb 域名？

### **被广泛认可并应用的 .bnb域名服务且拥有丰富的资源**

* SPACE ID 是广泛被 BNB 生态所认可的域名服务。SPACE ID 的第一个 TLD .bnb 域名从九月公开注册至今，短短两个月，目前 .bnb 域名已经集成60多个BNB 生态合作，包括 Wombat Exchange，DODOdex，Trust Wallet 等顶级生态项目。并且 BNB Chain 团队本身也在继续向 SPACE ID 引入所有更多的合作伙伴关系。
* Galxe 作为我们紧密的合作伙伴，也将持续向我们介绍更多优质项目。

### **统一身份的重要性**

对比 web2 和 web3，在 web2 中，可能你持有 *<arton@gmail.com>* 作为你的电子邮件，arton123 作为你的 Twitter 账号，甚至Arton6780 作为你的 discord 账号，你已经默认你在不同的平台会拥有不同的身份。但是在一个 .bnb 域名就可以整合你整个 web3 身份，包含游戏、NFT、Metaverse、web3 社交网络，x-to-earn，资产组合等等。

### **BNB Chain 链上活跃的交互**

BNB 上的每日活跃地址数量是包括以太坊在内的其他链的 2 至 4 倍以上。此外，域名一旦铸造，就不能消失。那么，当越来越多的人开始使用 Dapps 和钱包的时候，以及越来越多的人加入 web3 之后，越早期拥有域名，你也将有更多的可能性。

## 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://community.space.id/space-id-bai-ke-zhi-nan/ji-ben-jie-shao/wei-shen-me-yao-yong-you-.bnb-yu-ming.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.
