Design of Green Power Certificate Trading Mechanism Based on Blockchain Technology

In order to alleviate the problem of renewable energy gap and promote the development of green power, green power certificate transaction, as a supporting policy of renewable energy quota system, came into being. However, as China's green power certificate market is still in its infancy, there are still many problems in the market transaction. This paper analyzes the problems of green certificate trading in China from trading process and trading mode, and briefly analyzes some important characteristics of blockchain technology. The whole life cycle of green certificate circulation is divided into three links: issuance, transaction and verification. Some characteristics of blockchain technology are introduced into each link to solve the existing problems and optimize the efficiency and security of the whole process.
