Hyperledger Fabric背书策略的提案分发改进方案

Hyperledger Fabric Endorsement Strategy Proposal Distribution Improvement Plan

摘要: Hyperledger Fabric是当前最热门的联盟链技术之一，在大量的领域得到了应用。Fabric的背书节点的验证阶段通常都是系统的性能瓶颈。由于背书节点的数量固定，提案请求往往得不到及时的处理，影响系统的吞吐量。本文提出了一种根据当前物理资源动态调整背书节点的机制。根据实验分析，优化后的Hyperledger fabric具有更快的交易处理速度，在背书成功率仅下降1%的前提下，数据上链的吞吐量提高了约19.6%，数据上链的平均时延下降了26.7%。

Abstract: Hyperledger Fabric is currently one of the most popular consortium chain technologies and has been applied in a large number of fields. The verification phase of the fabric endorsement node is usually the performance bottleneck of the system. The number of endorsement nodes is fixed, and proposal requests are often not processed in time to form a queue, which affects the throughput of the system. This paper proposes a mechanism to dynamically adjust endorsement nodes based on current physical resources. According to experimental analysis, the optimized fabric has a faster transaction processing speed, and the throughput is increased by about 19.6%, and the average delay of data uploading has dropped by 26.7% under the premise that the endorsement success rate is only reduced by 1%.
