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 platform, 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.
