Electricity Carbon Emissions Data Storage Scheme Based on Hierarchical Blockchains

This article studies an important issue of secure and efficient storage of electricity carbon emissions data. We introduce a hierarchical blockchain system for storing electricity carbon emission data, addressing large-scale, high-concurrency data requests while ensuring security and immutability. The structure includes leaf, intermediate, and root blockchains for efficient storage and synchronization. Key aspects are identity registration, data upload and download organized by role-based interfaces. Experimental results demonstrate the system’s practicality and low overhead, making it as a secure and scalable solution for carbon emission data storage.
