This paper proposes a blockchain protection method based on distributed storage and reference value systems to prevent solar eclipse attacks in blockchain networks. Despite the inherent reliability and security provided by the decentralization of blockchain to a certain extent, potential network attacks that pose significant threats still exist. In response to these representative network attacks, particularly eclipse attacks, traditional solutions have primarily focused on controlling access nodes. While ensuring security, these solutions hinder the joining of new nodes and subsequent expansion of network. Therefore, this paper introduces an extensible method based on a reference value system and distributed storage. The method transfers the risk of nodes in the network falling victim to eclipse attacks through the reference value system and significantly reduces this risk through distributed storage. Finally, we analyze the proposed solution by creating a simulated network environment. The analysis results demonstrate that the proposed solution effectively mitigates the impact of eclipse attacks.
