Blockchain Architecture Design and Multi-Party Security Analysis of Power Metering Data Sharing Platform

Abstract

Aiming at the problems of data security and privacy protection in the traditional power metering data sharing mode, this paper puts forward an architecture design of power metering data sharing platform based on blockchain, and deeply analyzes its multi-party security. The platform adopts hierarchical architecture, including data layer, network layer, consensus layer, contract layer and application layer. The data can not be tampered with and can be traced through distributed ledger technology, and the improved DPoS consensus algorithm and intelligent contract technology are used to ensure data consistency and automatic processing. In terms of security, differential privacy, zero-knowledge proof and improved PBFT fault-tolerant model are adopted to effectively resist data tampering, unauthorized access and potential attacks. Through case analysis, the results show that the platform has obvious advantages in data integrity protection, access control, privacy protection and inter-agency collaboration efficiency improvement, and shows good adaptability in resource consumption. The research shows that blockchain technology provides a safe, efficient and reliable solution for power metering data sharing.
