区块链作为一种在没有集中式系统的情况下在多个节点上对注册信息进行分布式管理的技术，已经引起了人们的极大关注。然而，它们具有低事务吞吐量和长的批准时间的缺点。这些问题可以通过缩短块生成间隔来解决;然而，仅缩短此间隔就会增加分叉的频率。在这项研究中，我们的目标是缩短块生成间隔，而不增加分叉生成率，通过改善网络拓扑结构的节点和缩短传播时间。我们提出了一种邻居节点选择方法，形成一个网络拓扑结构，具有较短的块传播时间。使用区块链模拟器来演示所提出的邻居节点选择方法对网络传播延迟的影响。这一结果表明，该方法提高了块传播时间。
Blockchains have attracted a great deal of attention as a technology for the distributed management of register information at multiple nodes without a centralized system. However, they possess the drawbacks of low transaction throughput and long approval time. These problems can be addressed by shortening the block generation interval; however, shortening this interval alone has the effect of increasing the frequency of forks. In this study, we aim to shorten the block generation interval without increasing the fork generation rate by improving the network topology of the nodes and shortening the propagation time. We propose a neighbor node selection method forming a network topology with a short block propagation time. A blockchain simulator is used to demonstrate the effect of the proposed neighbor node selection method on the propagation delay of the network. This result indicates that the proposed method improves block propagation time.
