Abstract: Based on the needs of production planning and scheduling, the smart grid collects real-time electricity usage information from users, while fine-grained data collection brings privacy issues to users. In response to this problem, this paper proposes an Electricity Consumption Information Storage Blockchain （ECISB） scheme based on blockchain technology, in which no trusted center is needed, and one chain is used for the multi-user real-time multi-dimensional aggregated power consumption data is stored, and the other chain is used to store the power consumption in a single-user billing cycle. The double-chain design not only ensures the real-time power consumption data collection of the smart grid, but also solves the problem that the single-user power consumption cannot be measured in the traditional scheme.
