High Degree Nodes Connectivity Preference on Ethereum Transaction Network

Abstract

In this paper, we explored the Transaction Network on Ethereum from August 7, 2015 to November 22, 2024 with the perspective of complex network science. We aim to identify key network characteristics, such as disassortativity and core nodes stability. Our analysis reveals that high-degree nodes, typically mining pools and exchanges, preferentially connect with lowdegree nodes and rarely connected with each other. Additionally, we find that the ETN core structure remains robust over time. These findings contribute to blockchain network regulation and offer insights for future research into cryptocurrency transaction dynamics.
