接口說明
用於訂閱高性能網絡中的區塊數據流，方法名NewBlocks。高性能網絡根據區塊是否經過狀態驗證，提供兩種類型的数据流。
未驗證的區塊數據流：在高性能網絡上广播但狀態尚未經驗證的全部區塊，部分區塊可能無效，对于速度更敏感的用户可选择订阅。
已驗證的區塊數據流：在高性能網絡上广播且狀態經過驗證的區塊，傳播速度相比前者可能慢50-200ms。

請求參數
| 參數 | 必選 | 格式 | 示例 | 描述 |
|---|---|---|---|---|
NodeValidation | 是 | boolean | true | 默認為false，接收全量區塊數據流，包含未經状态驗證的新區塊，如設置為true，則接收經過状态驗證的區塊數據流。 |
