Hyperledger Besu QBFT以太坊区块哈希计算及验证问题求助

我在自己的Hyperledger Besu QBFT网络中，通过DAPP获取了第123个区块的头部信息：

我尝试用Hyperledger Besu项目里的Clique和IBFT区块哈希测试类来验证该区块哈希，但输入正确数据计算后，结果和区块头里的哈希不匹配，请问该如何正确计算Hyperledger Besu QBFT以太坊区块哈希？

• 认准QBFT的哈希逻辑归属：QBFT是IBFT 2.0的变体，哈希计算逻辑完全基于IBFT实现，和Clique无关。你用IBFT测试类的方向是对的，但要注意QBFT在区块头字段处理上的细节。
• 严格按固定顺序RLP序列化指定字段：以太坊区块哈希是对区块头的特定字段集合做RLP序列化后，再执行Keccak-256哈希得到的。QBFT需要包含的字段顺序必须严格遵循：
  parentHash、sha3Uncles、miner、stateRoot、transactionsRoot、receiptsRoot、logsBloom、difficulty、number、gasLimit、gasUsed、timestamp、extraData、mixHash、nonce
  顺序错、字段漏都会导致哈希结果错误。
• 直接使用原始extraData值：QBFT的extraData包含签名集合、提议者地址等结构化数据，必须直接使用区块头返回的十六进制extraData原始值，不能解析或修改后再序列化。
• 数值字段需转大端字节序二进制：所有数值类型字段（number、difficulty、gasLimit等）都要转换成大端字节序的原始二进制，比如number是0x7b，要转成对应的1字节二进制，不能用字符串或十进制数值。
• 对齐Besu核心实现逻辑：Besu中QBFT区块哈希的计算核心在BftBlockHashFunction类，它通过BlockHeaderEncoder.encodeWithoutHash方法对指定字段RLP编码，再做Keccak-256哈希。检查你的代码：
  • 序列化时必须排除hash字段本身
  • 确保所有字段的编码符合以太坊RLP规范
• 排查常见错误点：
  • 不要把totalDifficulty、size、baseFeePerGas这些不参与哈希计算的字段加入序列化集合
  • 确认超大数值（比如gasLimit）的字节转换正确
  • 检查extraData是否完整无修改
  • 必须使用Keccak-256哈希算法，而非SHA-256或其他算法
