As a distributed infrastructure and computing paradigm, blockchain technology has the advantages of decentralization, openness, and transparency, and it can support the construction of Energy Internet in the aspects of peer-to-peer transaction, privacy protection, trading market management, demand management and home energy management. With the development of blockchain technology, the combination of blockchain and Energy Internet is expected to become the core and focus of China’s energy system construction under the new infrastructure construction in the next stage. At present, pilot work of “blockchain + energy internet” has been gradually launched in China, and some periodical achievements have been made. However, it has encountered difficulties in large-scale promotion.Emphasis will be placed on the in-depth analysis of the “defects” of pilot projects, and the hidden dangers of current relevant works are identified based on practical cases. A series of countermeasures and relevant suggestions on the construction of “blockchain + Energy Internet” projects proposed can be used as a supplement to the research works in this field, providing reference for large-scale commercial applications and the formulation of relevant policies and standards in the future.
