Coupled with the emergence of buildings for future energy producers and distributors, distributed metering and trading of energy will become mainstream. The current centralized power grid control mode and the unified power grid data collection method will face huge challenges in the future.

The emergence of bitcoin in 2009 brought a disruptive result-blockchain technology. Blockchain is a secure database of account books, consisting of data blocks. Users can continuously update and upgrade here. For financial institutions, blockchain can speed up transaction processing, reduce costs, reduce middlemen, improve market insight, and increase business transparency.

Blockchain, as the underlying technology of cryptocurrency Bitcoin, can be used to combat fraud and illegal transactions. At present, many industries have begun to use blockchain technology, especially using blockchain as a tool to achieve true energy Internet technology.

Third, the fusion of blockchain and big data and artificial intelligence constitutes a trusted oracle, signs external data, and implements self-discipline control of virtual and real interactions. Fourth, the point-to-point interactive decision-making between devices based on blockchain deployment does not require trust to be delegated to a centralized platform for decision-making, and decentralization to achieve device democracy and distributed decision-making. Fifth, based on a clear interaction between the subjects Rules play a random game, and the system presents a neutral and benign evolution, which is in line with the laws of marketization and the coordination and evolution of competitive evolution.
