摘要
区块链是一种去中心化的基础架构和分布式计算范式,从比特币延伸至金融、物联网、能源交易等领域.在能源交易系统中,区块链可以帮助达成共识,突破各参与主体间缺乏信任的瓶颈,同时可以推动能源交易系统实现去中心化自治.本文首先介绍了能源交易系统和区块链技术的特点,分析了区块链技术对能源交易系统的适用性,并整理了国内外相关已落地项目;在此基础上,分析了基于区块链的能源交易系统面临的安全和隐私保护方面的挑战,并从数据层、网络层、合约层和应用层4个方面总结了现有的解决方案,同时根据不同方案所使用的安全和隐私保护技术进行了分类比较;最后对基于区块链的能源交易系统的安全和隐私保护的相关研究进行了展望.
Blockchain is a decentralized infrastructure and distributed computing paradigm extending from Bitcoin to finance,Internet of Things,energy trading and other fields.In energy trading systems,blockchain can break the bottleneck of lack of trust between participants to reach a consensus and promote energy trading system to realize decentralization and autonomy.Firstly,the characteristics of energy trading system and blockchain technology were introduced,and the applicability of blockchain technology to energy trading system was analyzed,in the meanwhile,relevant projects that have been implemented were compiled.Based on these,the challenges of blockchain-based energy trading system for security and privacy-preserving challenges were analyzed.From four major aspects:data layer,network layer,contract layer and application layer,the existing solutions were summarized,and classification comparison according to the security and privacy-preserving technologies used in different schemes was made.Finally,the research on security and privacy protection of energy trading system based on blockchain was prospected.
