The invention discloses a
green power certificate issuing
system , which comprises a device and a block chain, and is characterized in that the device is authenticated by an issuing unit in advance, and the block chain comprises a user account contract and an asset issuing contract. In practical application, the
system directly obtains reliable power generation data from an electric meter throughequipment, automatically calculates the number of
green power certificates according to the power generation data, carries out equipment
authentication through a
blockchain, and automatically issues the
green power certificates to a user account. The process of manually checking the power generation data is avoided, the issuing efficiency of the green power
certificate is improved, and the reliability and credibility of the issuing process of the green power
certificate can be ensured based on the
blockchain technology. In addition, the invention further provides a green power certificate issuing method and device based on the block chain and the block chain, and the technical effect of the green power certificate issuing method and device corresponds to the technical effect of the
system.
