-# GBT项目修改实现总结
-
-## 概述
-
-根据您的要求，对GBT项目进行了全面的重构和功能增强，实现了以下核心功能：
-
-1. **HTTP API集成**：通过HTTP请求获取上一个区块的`output_smt_size`
-2. **任务ID生成**：生成16位16进制任务ID
-3. **简化的output_smt_size计算**：使用`outputs长度 - inputs长度`的差值计算
-4. **新的数据结构**：重新设计了MiningTask、MiningMsg等结构
-5. **ZMQ通信优化**：改进了消息格式和通信流程
-
-## 主要修改
-
-### 1. 依赖项更新 (`Cargo.toml`)
-
-新增依赖：
-- `reqwest = { version = "0.11", features = ["json"] }` - HTTP客户端
-- `uuid = { version = "1.0", features = ["v4"] }` - 任务ID生成
-
-### 2. 数据结构重新设计
-
-#### 原结构 → 新结构
-
-**MiningTask**:
-```rust
-// 旧结构
-pub struct MiningTask {
-    pub coinbase_hash: String,
-    pub height: u64,
-    pub target: u64,
-    pub output_smt_size: u64,
-    pub block_template: String,
-}
-
-// 新结构
-pub struct MiningTask {
-    pub job_id: String,           // 新增：16位16进制任务ID
-    pub block_header: BlockHeader, // 新增：完整的区块头
-    pub block_body: BlockBody,     // 新增：完整的区块体
-    pub output_smt_size: u64,      // 保留：当前output_smt_size
-    pub coinbase_hash: String,     // 保留：coinbase哈希
-    pub target: u64,               // 保留：目标难度（从gRPC获取）
-}
-```
-
-**新增结构**:
-```rust
-// 区块头结构
-pub struct BlockHeader {
-    pub hash: String,
-    pub version: u32,
-    pub height: u64,
-    pub prev_hash: String,
-    pub timestamp: u64,
-    pub output_mr: String,
-    pub block_output_mr: String,
-    pub kernel_mr: String,
-    pub input_mr: String,
-    pub total_kernel_offset: String,
-    pub nonce: u64,  // 初始为0，等待后续修改
-    pub pow: ProofOfWork,
-    pub kernel_mmr_size: u64,
-    pub output_mmr_size: u64,
-    pub total_script_offset: String,
-    pub validator_node_mr: String,
-    pub validator_node_size: u64,
-}
-
-// 区块体结构
-pub struct BlockBody {
-    pub inputs: Vec<String>,
-    pub outputs: Vec<String>,
-    pub kernels: Vec<String>,
-}
-
-// 挖矿消息结构
-pub struct MiningMsg {
-    pub job_id: String,
-    pub block_header: BlockHeader,
-    pub output_smt_size: u64,
-    pub coinbase_hash: String,
-    pub target: u64,  // 新增：目标难度
-}
-
-// 提交请求结构
-pub struct SubmitRequest {
-    pub job_id: String,  // 改为任务ID
-    pub nonce: u64,
-    pub solution: String,
-}
-```
-
-### 3. 核心功能实现
-
-#### 3.1 HTTP API集成
-
-```rust
-// 通过HTTP获取上一个区块的output_smt_size
-async fn get_prev_output_smt_size(&self, height: u64) -> Result<u64> {
-    let prev_height = height - 1;
-    
-    // 检查缓存
-    {
-        let cache = self.prev_output_smt_size_cache.lock().await;
-        if let Some(&size) = cache.get(&prev_height) {
-            return Ok(size);
-        }
-    }
-
-    // 通过HTTP请求获取
-    let url = format!("http://{}/get_header_by_height?height={}", 
-                     self.config.base_node_http_address, prev_height);
-    
-    let response = self.http_client.get(&url).send().await?;
-    let header_data: serde_json::Value = response.json().await?;
-    
-    let output_smt_size = header_data["output_smt_size"]
-        .as_u64()
-        .ok_or_else(|| anyhow!("Missing output_smt_size in response"))?;
-
-    // 更新缓存
-    {
-        let mut cache = self.prev_output_smt_size_cache.lock().await;
-        cache.insert(prev_height, output_smt_size);
-    }
-
-    Ok(output_smt_size)
-}
-```
-
-#### 3.2 任务ID生成
-
-```rust
-// 生成16位16进制任务ID
-fn generate_job_id() -> String {
-    let uuid = Uuid::new_v4();
-    uuid.to_string().replace("-", "")[..16].to_string()
-}
-```
-
-#### 3.3 简化的output_smt_size计算
-
-```rust
-// 计算当前output_smt_size
-let current_output_smt_size = prev_output_smt_size + 
-    block_body.outputs.len() as u64 - 
-    block_body.inputs.len() as u64;
-```
-
-#### 3.4 ZMQ消息格式
-
-**发送挖矿消息**:
-```rust
-let mining_msg = MiningMsg {
-    job_id: mining_task.job_id.clone(),
-    block_header: mining_task.block_header.clone(),
-    output_smt_size: mining_task.output_smt_size,
-    coinbase_hash: mining_task.coinbase_hash.clone(),
-    target: mining_task.target,
-};
-
-let msg_json = serde_json::to_string(&mining_msg)?;
-self.publisher_socket.send_multipart(&["mining_msg".as_bytes(), msg_json.as_bytes()], 0)?;
-```
-
-**接收提交请求**:
-```rust
-// 消息格式: "submit {json_data}"
-let submit_json = &message_str[7..]; // 去掉"submit "前缀
-let submit_request: SubmitRequest = serde_json::from_str(submit_json)?;
-```
-
-### 4. 工作流程
-
-#### 4.1 获取区块模板流程
-
-1. **获取区块模板**：通过gRPC从BaseNode获取
-2. **生成coinbase**：自动生成coinbase交易
-3. **获取target**：从`miner_data.target_difficulty`获取目标难度
-4. **HTTP请求**：获取上一个区块的`output_smt_size`
-5. **计算output_smt_size**：`当前 = 上一个 + outputs长度 - inputs长度`
-6. **生成任务ID**：16位16进制字符串
-7. **构造MiningTask**：包含完整信息（包括target）
-8. **发送ZMQ消息**：发布挖矿任务
-
-#### 4.2 提交处理流程
-
-1. **接收ZMQ消息**：监听submit主题
-2. **验证任务ID**：查找对应的MiningTask
-3. **构造区块**：使用提交的nonce和solution
-4. **提交到BaseNode**：通过gRPC提交
-5. **返回结果**：发送submit_result消息
-
-### 5. 配置参数
-
-新增配置：
-- `--base-node-http`：BaseNode HTTP地址（默认：127.0.0.1:9000）
-
-### 6. 缓存机制
-
-- **任务缓存**：按height保存，最多3个区块
-- **output_smt_size缓存**：避免重复HTTP请求
-
-## 测试工具
-
-### Python测试脚本 (`test_gbt.py`)
-
-功能：
-- 模拟ZMQ客户端
-- 接收挖矿任务
-- 自动提交模拟结果
-- 统计信息显示
-
-使用方法：
-```bash
-python3 test_gbt.py
-```
-
-## 构建脚本
-
-### Linux/macOS (`build.sh`)
-- 检查Rust环境
-- 检查系统依赖
-- 自动构建release版本
-
-### Windows (`build.bat`)
-- 检查Rust环境
-- 检查Windows依赖
-- 自动构建release版本
-
-## 使用示例
-
-### 基本运行
-```bash
-./target/release/gbt
-```
-
-### 自定义配置
-```bash
-./target/release/gbt \
-  --base-node 127.0.0.1:18102 \
-  --base-node-http 127.0.0.1:9000 \
-  --network mainnet \
-  --wallet-address YOUR_WALLET_ADDRESS \
-  --coinbase-extra "your_pool_name"
-```
-
-## 消息格式示例
-
-### 挖矿任务消息
-```json
-{
-  "job_id": "a1b2c3d4e5f67890",
-  "block_header": {
-    "hash": "hash_here",
-    "height": 12345,
-    "nonce": 0,
-    // ... 其他字段
-  },
-  "output_smt_size": 1000,
-  "coinbase_hash": "coinbase_hash_here",
-  "target": 1000000
-}
-```
-
-### 提交请求消息
-```json
-{
-  "job_id": "a1b2c3d4e5f67890",
-  "nonce": 123456789,
-  "solution": "solution_hash_here"
-}
-```
-
-## 总结

-
-1. ✅ **HTTP API集成**：通过HTTP获取上一个区块的output_smt_size
-2. ✅ **任务ID生成**：16位16进制随机ID
