Abstract:

Blockchain is an emerging hot spot when the transition from traditional energy to low-carbon，green and digitalized one is imperative.Energy blockchain based on blockchain technology can become an effective booster of China's energy transformation and pattern evolution.In order to comprehensively understand blockchain technology and its current status，and get its development direction，the introduction of the origin and historical background of blockchain was made，in which the concept，typical features，categories and development process of blockchain and distributed ledger technologies were described and analyzed. Then，the main international standards related to blockchain and distributed
ledger technologies came from ISO（International Organization for Standardization），ITU（International Telecommunication Union），IEEE（Institute of Electrical and Electronics Engineers），etc.were systematically expounded from their status quo and development. In addition，analysis on the necessity of developing energy blockchain was made according to eleven application scenarios in energy field. Finally，six main anti-measures in risk controlling for energy blockchain were summarized，with the aim of promoting the healthy and rapid development of energy blockchain researches and applications in China.
