+# Issue #007 NRPC4.0升级完成报告
+
+## 📋 工单信息
+
+- **工单编号**: #007
+- **工单标题**: nac-api-server API服务器完善 (P1-高)
+- **完成日期**: 2026-02-19
+- **完成人**: NAC Team
+- **升级内容**: NRPC4.0协议集成（5%）
+
+## ✅ 升级内容
+
+### 1. NRPC4.0协议集成
+
+#### 1.1 依赖更新
+- **文件**: `Cargo.toml`
+- **变更**: 添加nac-nrpc4依赖
+```toml
+# NAC NRPC4.0协议
+nac-nrpc4 = { path = "../nac-nrpc4" }
+```
+
+#### 1.2 客户端重写
+- **文件**: `src/blockchain/client.rs`
+- **变更**: 从JSON-RPC升级到NRPC4.0
+- **代码行数**: 208行 → 422行 (增长103%)
+
+**主要改进**:
+
+1. **连接管理**
+   - 使用NRPC4.0连接池
+   - 配置连接超时、空闲超时
+   - 心跳机制（10秒间隔，5秒超时）
+   - 连接复用支持
+
+2. **重试机制**
+   - 指数退避策略
+   - 最大重试3次
+   - 初始延迟1秒，最大延迟10秒
+
+3. **日志记录**
+   - 完整的操作日志
+   - 错误追踪
+   - 性能监控
+
+4. **NRPC4.0协议**
+   - 自定义请求/响应格式
+   - 时间戳支持
+   - 错误详情（code + message + data）
+   - HTTP头：`Content-Type: application/nrpc4+json`
+   - HTTP头：`X-NRPC-Version: 4.0`
+
+#### 1.3 API方法升级
+
+所有RPC方法已升级到NRPC4.0格式：
+
+1. **get_balance** - 获取账户余额
+   - 请求方法: `nac_getBalance`
+   - 参数: `{"address": "..."}`
+   - 返回: `BalanceInfo`
+
+2. **send_transaction** - 发送交易
+   - 请求方法: `nac_sendTransaction`
+   - 参数: `Transaction`
+   - 返回: 交易哈希
+
+3. **get_transactions** - 获取交易历史
+   - 请求方法: `nac_getTransactions`
+   - 参数: `{"address": "...", "limit": 100}`
+   - 返回: `Vec<TransactionInfo>`
+
+4. **get_transaction** - 获取交易详情
+   - 请求方法: `nac_getTransaction`
+   - 参数: `{"hash": "..."}`
+   - 返回: `TransactionInfo`
+
+5. **get_block_height** - 获取区块高度
+   - 请求方法: `nac_blockNumber`
+   - 参数: `{}`
+   - 返回: `u64`
+
+#### 1.4 测试更新
+
+所有测试已更新以适配NRPC4.0：
+
+1. **test_client_creation** - 客户端创建测试
+2. **test_nrpc_request_serialization** - 请求序列化测试
+3. **test_nrpc_response_deserialization** - 响应反序列化测试
+4. **test_nrpc_error_response** - 错误响应测试
