分数，最后大家取平均分作为用户评分。 数据共识：每个节点副本执行pbft/raft共识后上链的数据 业务共识：当3家机构都对用户评级后，用户的信用才会生效 以上，我们归结为“业务共识” 弹性联盟链共识框架方案设计 在定义了业务共识的基础上，我们引入弹性联盟链共识框架方案，即在现有的 共识上添加可以由用户编写的规则来限制共识是否成功。 目前这个功能只用于PBFT，RAFT还未支持。 注：弹性联盟链共识 前的区块链平台大多是不能直接支持的。 “数据导出服务”是一个用于构建“区块链数据仓库”的解决方案，使区块链和已 经为人熟知的关系型数据，分布式数据库，大数据平台进行有机结合。 为区块链设置一个准实时的数据ETL（Extract-Transform-Load）流程，使得链 上一旦新生成区块，就能立刻把相关的区块证明，区块里包含的交易列表、交 易明细、交易结果、智能合约状态数据、链上配置信息等全部导入到链外的数 ，借助数据仓库本身强 大的查询能力、分析能力和数据挖掘能力，可以对区块链上产生的数据进行复 杂的整合和加工，以满足商业智能、监管监控、反洗钱、数据报送等场景的需 求。 数据导出服务里通用的部分如ETL定时任务，区块导出，交易导出，状态数据 导出等，可以由区块链平台提供参考实现，具体到业务数据，如链上的订单数 据，转账数据和交易结果等，则和业务密切相关，需要业务开发者针对具体的 数据结构进行解析
