摘　　要：介绍了目前解决区块链存储问题的研究进展及解决方案。结合智慧用电平台边缘侧区块链的部署情况,在区块链轻型应用方面,采用分布式哈希表(DHT)分布式区块链存储方式实现边侧区块链数据存储。通过边侧区块链节点历史区块数据定时备份、共识算法多样选择和区块链镜像裁剪等方法配合实现边侧区块链节点的轻量化。指出随着电力物联网技术应用场景的丰富和持续发展,仍需持续深入研究,以寻找更加优化的算法模型和解决方案。This paper first introduces various researches and solutions to solve the problem of blockchain storage at present.Secondly,combined with the deployment of blockchain on the edge side of the intelligent electricity plaform,DHT distributed blockchain storage is adopted.At the same time,regular backup of historical side block data,multiple selection of consensus algorithms,and blockchain mirror cutting are used to realize the lightweight of side blockchain nodes.Finally,it is pointed out that with the enrichment and continuous development of application scenarios of the electricity internet of things,this topic still needs further research to find more optimized algorithm models and solutions.
