# 基础知识

## 网络成本Gas是如何确定的？

**网络成本是支付给您用于加密货币交易的网络矿工的费用。**

\
这笔费用也称为Gas fee。

区块链上的每笔交易都需要网络成本。这是因为矿工使用自己的计算机来验证和处理交易，而不是依赖中央机构。

作为回报，矿工得到补偿。以太坊区块链以以太币 (ETH) 向矿工支付费用，称为 gwei。 \
\
网络成本由矿工的供需决定。

当网络流量较大（交易量较大）时，网络成本较高。当网络流量较低（交易量较低）时，网络成本较低。

## 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.darkhole.io/cn/copy-of-chang-jian-wen-ti/ji-chu-zhi-shi.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.
