引入依赖

• log: Tendermint 的日志
• auth: Cosmos SDK 的auth模块
• dbm: Tendermint 的数据库代码
• baseapp: 如下

BaseApp

sequenceDiagram  
    participant Client as 客户端  
    participant Tendermint as Tendermint 共识引擎  
    participant BaseApp as BaseApp  
    participant Module as 模块  
    participant State as 状态  
    participant Query as 查询  

    Client->>Tendermint: 发送交易  
    Tendermint->>BaseApp: 接收到交易  
    BaseApp->>BaseApp: 解码交易  
    BaseApp->>BaseApp: 提取 messages  
    BaseApp->>BaseApp: 进行基本合理性校验  
    BaseApp->>Module: 路由到合适的模块  
    Module->>BaseApp: 处理 message  
    BaseApp->>Tendermint: 处理结果  

    alt ABCI 消息是 DeliverTx 或 CheckTx  
        BaseApp->>Tendermint: 提交交易 Commit
    end  

    BaseApp->>Module: 调用 BeginBlock  
    Module->>BaseApp: 执行 BeginBlock 逻辑  
    BaseApp->>Module: 调用 EndBlock  
    Module->>BaseApp: 执行 EndBlock 逻辑  

    BaseApp->>State: 初始化状态  state
    BaseApp->>Query: 设置查询queries
