New energy power tracing method and system based on block chain

The invention discloses a new energy power tracing method and system based on a block chain, and the method comprises the steps of storing an electricity purchasing transaction contract, a new energyscheduling plan curve and a new energy power consumption order in the block chain, analyzing, obtaining the key field information format data, scheduling and correlating the curve hash data and the order information format data to generate a green electricity token with a unique identifier, storing the green electricity token on the block chain, and tracing by tracing a digital identifier. According to the invention, based on the mechanisms, such as a distributed account book of the block chain, data privacy security, data precision authentic right, etc., the information barriers of a transaction center, scheduling and power utilization sides are broken through, and data sharing and cooperation are promoted; the working efficiency is improved efficiently through a distributed data accountbook, the storage safety a
