# 节点客户端

TRON 客户端是指实现了 TRON Protocol 并参与在 P2P 网络中与其他 TRON 客户端交换信息共同构成整个 TRON 网络的程序。

TRON 目前只有唯一实现 \[java-tron]\(<https://github.com/tronprotocol/java-tron>).

### 节点类型

一般来说，TRON 节点分为以下几种：

* SR 节点。产块节点，设置了 SR 私钥，有产块能力。也称作超级代表节点，超级节点等。
* 普通节点(Full Node)。参与 TRON 网络的全节点，拥有全量区块数据和状态数据。一般会对外对内提供 API 服务。
* 轻节点。未实现。

### 主网和测试网

公链一般会有自己的主网(Mainnet)，同时还提供若干测试网(Testnet)供开发者和用户测试开发使用。

TRON 的所有主网和测试网信息如下：

# Agent Instructions
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://andelf.gitbook.io/tron/introduction/client.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.
