A Study of Using Plumtree Algorithm in Blockchain Networks

抄録

Blockchain is gaining attention as a technology to support cryptocurrency. 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 duplicate messages in a blockchain network by applying Plumtree algorithm. Through simulation experiments, we confirmed that the number of messages can be reduced by more than 70% when block propagation is simulated up to 50 blocks.
