From a scientific and technological point of view, blockchain technology involves many scientific and technological issues such as math class, cryptographic algorithm, big data technology and computer programming. From the application point of view, in short, blockchain is the resource ledger and database of 1 distributed framework, which has the characteristics of decentralization, unforgeability, traceability of the whole process, collective maintainability, openness and transparency. According to this feature, blockchain technology has established a reliable "trust" foundation and created a reliable "collaboration". The system has wide application value. In recent years, the global mentality of Bitcoin has fluctuated, but blockchain technology, as one of the basic technologies of Bitcoin, has attracted more and more attention. In the process of bitcoin generation, a block is a storage unit, which records all the information exchange of each block node in the corresponding time period. The middle link of each block is realized according to random distribution (also called hash algorithm), and the latter block contains the hash value of the latter block. With the expansion of information content exchange, 1 block and 1 block continue, and the result is called blockchain technology.

As an auxiliary technology, blockchain technology does not disperse the whole energy network, but makes the energy network more closely linked. Each network can be "autonomous" while maintaining its independence. This independence can improve the working efficiency of each node and reduce the energy loss of the "intermediate link" of the working efficiency of each node.
