Abstract

This application provides a blockchain-based green certificate transaction system, including: audit nodes, proxy nodes, and off-chain nodes; proxy nodes are used by power producers and buyers; audit nodes verify the qualifications of power producers on proxy nodes Information, send a green certificate to the power producer on the proxy node; the off-chain node predicts the transaction price of the next transaction based on the historical transaction price and current environmental information; the proxy node receives the power producer’s sales information and the buyer’s purchase In the case of information, the sales information and the digital signature of the power producer, as well as the purchase information and the digital signature of the buyer are sent to the off-chain node, and the off-chain node matches the sales information and the purchase information, and the successful transaction information will be matched Send to the agent node; the agent node sends the successfully matched transaction information to the transaction smart contract; the transaction smart contract performs transaction processing according to the transaction information. This application can increase transaction volume.

Description

technical field [0001] This application relates to the field of green electricity certificate transactions, in particular to a blockchain-based green certificate transaction system. Background technique [0002] The Green Electricity Certificate, referred to as the Green Certificate, is an electronic certificate with a unique identification code issued by the state for each megawatt-hour of non-hydro renewable energy on-grid electricity. It is the confirmation and attribute certification of non-hydro renewable energy generation and the green power consumption It is also a policy tool of the renewable energy quota system. At present, the issuance of green certificates requires enterprises to submit relevant materials and then be reviewed by various departments. After some of them pass the review, green certificates will be issued to enterprises. Enterprises holding green certificates can sell green certificates, and green certificate transactions occur between the green cert...
