摘　　要：针对联盟链Fabric中,orderer节点一旦发生异常,只能在下一个时间间隔继续,而当前时间间隔浪费的问题,本文对Fabric体系结构进行了演化,提出了一种新的思路,使得orderer节点产生异常后,系统可以在当前间隔内正常工作,不必等到下一个时间间隔。最后通过实验对算法在吞吐量、资源利用率等性能指标上进行了对比分析,表明了Fabric软件软件体系结构演化算法的有效性。In order to solve this problem: at the alliance chain Fabric, if the orderer node has an exception, it can only continue at the next time interval and the current time interval is wasted, this paper proposes a new idea to evolve the fabric architecture, so that after the orderer node has an exception, the system can work normally in the current interval without waiting for the next time interval. Finally, the algorithm was compared and analyzed through experiments on performance indicators such as throughput and resource utilization, which showed the effectiveness of the evolutionary algorithm of the Fabric software architecture.
