The Electronic Power Data Traceability Model Based on Hybrid Consensus and IPFS

To address power data security issues and the lack of data trust among different entities, this paper proposes a traceability model for power data. The utilization of blockchain technology ensures the feasibility and security of data traceability through its tamper-proof and traceable nature. The model incorporates a data storage scheme based on the interplanetary file system (IPFS), which effectively reduces storage costs and the burden on the blockchain while ensuring data security. Additionally, the model employs a hybrid consensus mechanism relying on a reputation system to overcome the drawbacks of high energy consumption and low work efficiency in traditional proof-of-work (PoW) consensus and the issue of node monopoly in traditional proof-of-stake (PoS) consensus. Experimental results demonstrate that the hybrid consensus mechanism significantly reduces block time, mitigates the risk of malicious nodes, and enhances the work efficiency and security of the model.
