联盟链缺少展示各个节点资源使用情况、健康状态、互相关系、共识交易流程等方面的可视化方法,为此提出一种基于自定义日志的fabric共识交易轨迹追踪方法(FTL)。首先,以典型联盟链框架hyperledger fabric为基础设施实现区块链底层构建;然后,利用ELK工具链收集与解析fabric的自定义共识交易日志,并利用Spring Boot作为业务逻辑处理框架;最后,采用专注于图分析领域的Graphin实现共识交易轨迹的可视化。实验结果表明,与原生fabric应用相比,基于FTL的fabric的应用框架在实现可视化追踪基础后,平均性能仅下降了8.8%,未造成显著延迟,可以为监管方提供更加智能的区块链监管方案。
