公链启动过程安全分析教学文档<\/h1>

1. 概述<\/h2>
本教学文档详细解析公链（以以太坊为例）的启动过程，涵盖节点启动、账户管理、事件监听、挖矿操作等核心环节的安全分析。<\/p>

2. 节点启动过程<\/h2>

2.1 startNode函数<\/h3>
startNode<\/code>函数是公链启动的核心函数，接受三个参数：<\/p>

ctx<\/code>: 上下文对象<\/li>
stack<\/code>: node.Node类型的指针<\/li>
backend<\/code>: ethapi.Backend类型的对象<\/li>
<\/ul>
主要功能：<\/p>

添加内存监控<\/li>
启动节点<\/li>
解锁账户<\/li>
创建本地交互客户端<\/li>
处理钱包事件<\/li>
同步状态监控<\/li>
启动挖矿等辅助服务<\/li>
