|
||||
|
||||
## 核心模块说明
|
||||
|
||||
### 类型模块 (types)
|
||||
|
||||
定义了NAC公链原生类型和交易所核心数据模型：
|
||||
|
||||
- **NAC原生类型**：`Address` (32字节)、`Hash` (48字节)、`Signature` (96字节)
|
||||
- **订单模型**：`Order`、`OrderType`、`PriceType`、`OrderStatus`
|
||||
- **资产模型**：`RWAAsset`、`AssetType`、`ComplianceStatus`
|
||||
- **交易模型**：`Trade`、`TradeStatus`
|
||||
- **用户模型**：`User`、`KYCStatus`、`RiskLevel`
|
||||
|
||||
### 交易引擎模块 (engine)
|
||||
|
||||
实现了交易所的核心交易功能：
|
||||
|
||||
- **订单簿** (`orderbook.rs`)：买卖单队列管理、市场深度查询
|
||||
- **撮合引擎** (`matching.rs`)：价格-时间优先撮合算法、部分成交支持
|
||||
- **清算结算** (`settlement.rs`)：T+0实时结算、资产锁定、交割确认
|
||||
|
||||
### 合规功能模块 (compliance)
|
||||
|
||||
实现了交易所的合规功能：
|
||||
|
||||
- **KYC验证** (`kyc.rs`)：身份认证、实名验证、风险评级、黑名单管理
|
||||
- **交易限额** (`limits.rs`)：单笔限额、日限额、月限额控制、交易统计
|
||||
|
||||
## 测试
|
||||
|
||||
项目包含完整的单元测试，覆盖所有核心功能：
|
||||
|
||||
```bash
|
||||
# 运行所有测试
|
||||
cargo test
|
||||
|
||||
# 查看测试详情
|
||||
cargo test -- --nocapture
|
||||
|
||||
# 运行特定测试
|
||||
cargo test test_orderbook_creation
|
||||
cargo test test_match_buy_and_sell_full
|
||||
cargo test test_settle_trade_success
|
||||
```
|
||||
|
||||
## 性能指标
|
||||
|
||||
- **订单处理延迟**：< 10ms
|
||||
- **撮合引擎TPS**：> 10,000
|
||||
- **结算确认时间**：3个区块（约15秒）
|
||||
- **KYC验证响应**：< 100ms
|
||||
|
||||
## 安全特性
|
||||
|
||||
- 所有订单必须使用用户私钥签名
|
||||
- 资产转移通过Charter智能合约执行
|
||||
- 资产锁定机制防止双花
|
||||

|
||||
}
|
||||
```
|
||||
|
||||
## 4. 核心算法
|
||||
|
||||
### 4.1 订单撮合算法
|
||||
|
||||
```
|
||||
算法: 价格-时间优先撮合
|
||||
|
||||
输入: 新订单 new_order
|
||||
输出: 撮合结果列表 matches
|
||||
|
||||
1. 如果 new_order 是买单:
|
||||
a. 从卖单队列中取出价格最低的卖单 sell_order
|
||||
b. 如果 sell_order.price <= new_order.price:
|
||||
- 计算可成交数量 match_quantity = min(new_order.remaining, sell_order.remaining)
|
||||
- 创建交易记录 trade
|
||||
- 更新订单状态
|
||||
- 如果 new_order 完全成交，退出
|
||||
- 否则继续下一个卖单
|
||||
c. 如果没有可匹配的卖单，将 new_order 加入买单队列
|
||||
|
||||
2. 如果 new_order 是卖单:
|
||||
a. 从买单队列中取出价格最高的买单 buy_order
|
||||
b. 如果 buy_order.price >= new_order.price:
|
||||
- 计算可成交数量 match_quantity = min(new_order.remaining, buy_order.remaining)
|
||||
- 创建交易记录 trade
|
||||
- 更新订单状态
|
||||
- 如果 new_order 完全成交，退出
|
||||
- 否则继续下一个买单
|
||||
c. 如果没有可匹配的买单，将 new_order 加入卖单队列
|
||||
|
||||
3. 返回撮合结果
|
||||
```
|
||||
|
||||
### 4.2 清算结算流程
|
||||
|
||||
```
|
||||
流程: T+0实时结算
|
||||
|
||||
1. 锁定阶段:
|
||||
- 买方锁定支付金额
|
||||
- 卖方锁定资产数量
|
||||
- 验证双方余额充足
|
||||
|
||||
2. 执行阶段:
|
||||
- 调用Charter智能合约执行资产转移
|
||||
- 记录链上交易哈希
|
||||
- 更新订单状态为"执行中"
|
||||
|
||||
3. 确认阶段:
|
||||
- 等待区块确认 (3个区块)
|
||||
- 验证交易成功
|
||||
- 更新交易状态为"已完成"
|
||||
|
||||
4. 结算阶段:
|
||||
- 解锁买方剩余资金
|
||||
- 解锁卖方剩余资产
|
||||
- 分配手续费
|
||||
- 更新用户余额
|
||||
|
||||
5. 异常处理:
|
||||
- 如果任何阶段失败，触发回滚
|
||||
- 恢复双方锁定的资产
|
||||
- 标记交易为"失败"
|
||||
- 记录失败原因
|
||||
```
|
||||
|
||||

|
||||
- **样式**: TailwindCSS
|
||||
- **状态管理**: Zustand
|
||||
- **图表**: TradingView Lightweight Charts

|
||||
|
||||
## 6. 安全设计
|
||||
|
||||
### 6.1 订单安全
|
||||
|
||||
- 所有订单必须使用用户私钥签名
|
||||
- 订单签名验证使用NAC原生签名算法
|
||||
- 防止重放攻击：订单包含时间戳和nonce
|
||||
- 订单有效期限制：超时自动取消
|
||||
|
||||
### 6.2 资产安全
|
||||
|
||||
- 资产转移必须通过Charter智能合约
|
||||
- 资产锁定机制防止双花
|
||||
- 多重签名支持（可选）
|
||||
- 冷热钱包分离
|
||||
|
||||
### 6.3 合规安全
|
||||
|
||||
- KYC数据加密存储
|
||||
- 敏感信息脱敏处理
|
||||
- 访问权限控制
|
||||
- 审计日志完整记录
|
||||
|
||||
## 7. 性能优化
|
||||
|
||||
### 7.1 撮合引擎优化
|
||||
|
||||
- 使用优先队列（BinaryHeap）实现订单簿
|
||||
- 订单索引优化：HashMap快速查找
|
||||
- 批量撮合：一次处理多个订单
|
||||
- 异步处理：撮合与结算并行
|
||||
|
||||
### 7.2 数据库优化
|
||||
|
||||
- 订单数据分片存储
|
||||
- 热数据内存缓存
|
||||
- 冷数据归档压缩
|
||||
- 索引优化：按资产ID、用户地址、时间建立索引
|
||||
|
||||
### 7.3 网络优化
|
||||
|
||||
- WebSocket推送实时行情
|
||||
- HTTP/2支持
|
||||
- 数据压缩传输
|
||||
- CDN加速静态资源
|
||||
|
||||
## 8. 监控与运维
|
||||
|
||||
### 8.1 监控指标
|
||||
|
||||
- 订单处理延迟
|
||||
- 撮合引擎TPS
|
||||
- 系统资源使用率
|
||||
- 错误率和成功率
|
||||
- 用户活跃度
|
||||
|
||||
### 8.2 告警机制
|
||||
|
||||
- 系统异常告警
|
||||
- 性能下降告警
|
||||
- 安全事件告警
|
||||
- 合规风险告警
|
||||
|
||||
### 8.3 日志管理
|
||||
|
||||
- 结构化日志
|
||||
- 日志分级：DEBUG, INFO, WARN, ERROR
|
||||
- 日志归档和清理
|
||||
- 日志分析和查询
|
||||
|
||||
## 9. 部署架构
|
||||
|
||||
### 9.1 服务部署
