Abstract (in Japanese) (See Japanese page) 
(in English) Blockchain is gaining attention as a technology to support cryptocurrency. It is a system that prevents internal and external tampering by sharing a ledger for recording transactions among multiple computers on a network. However, one of the problems in using blockchain is the consumption of communication resources. It is caused by that the information received by a node can be delivered to the same node more than once through different neighbors. In this paper, we propose a method to reduce the number of duplicate messages in a blockchain network with random topology by applying an algorithm called Plumtree to fix the propagation path loosely. Through simulation experiments, we compared the proposed method with existing methods and confirmed that the number of messages can be reduced by more than 75 % when block propagation is simulated up to four blocks.
