代码增强说明

  1. 区块链存证系统​:新增Blockchain类,支持零知识证明(ZKP)存证与区块验证,模拟企业财务数据上链过程,确保信息不可篡改。
  2. 联邦学习审计​:FederatedLearningAuditor类实现跨机构联合模型训练(简化版FedAvg算法),在不共享原始数据的前提下提升审计准确率。
  3. 贡献值联动机制​:Enterprise类新增update_seci_value方法,根据审核结果动态调整文明贡献值(Sₑ),造假企业Sₑ清零,合规企业获得奖励。
  4. 智能合约审核​:SmartContract类模拟PBFT共识算法,多节点(交易所、证监会等)投票达成审核结果,替代传统人工审核。
  5. 全球标准映射​:calculate_cci函数将多国规则转化为可量化的文明合规指数(CCI),企业达标后自动获得多地上市资格。
  6. 动态能量关联​:Region类关联区块链系统,企业关键数据上链时触发能量消耗记录,确保生态与技术约束实时生效。
