In order to realize the theoretical analysis of the regional chain technology of the smart grid, to identify the needs and status of each device, and to ensure the safe and correct operation of the smart grid communication network, Liming Sun adopts a distributed and self-organizing form to form a network, and for each node Construct a backup network routing function and analyze the routing and relay services provided by the nodes.

Because of its decentralization, time traceability, autonomy, openness, and non-tamperability, the blockchain is considered to be a key technology to solve the security of distributed Internet of Things. Liming Sun made an experimental research report on how blockchain can help solve and ensure the integrity of fast, distributed, and complex energy transactions and data exchanges through repeated experimental research.
