Abstract

The invention provides a green certificate transaction system based on a block chain. The green certificate transaction system comprises an auditing node, an agent node and an off-chain node, the agent node is used by a power producer and a purchaser; the auditing node verifies the qualification information of the power producer on the agent node and sends a green certificate to the power producer on the agent node; the off-chain node predicts the transaction price of the next transaction according to the historical transaction price and the current environment information; when the agent node receives the selling information of the electric power producer and the purchasing information of the purchaser, the agent node sends the selling information, the digital signature of the electric power producer, the purchasing information and the digital signature of the purchaser to an off-chain node, and the off-chain node matches the selling information with the purchasing information; sending the successfully matched transaction information to the agent node; the agent node sends the successfully matched transaction information to the transaction intelligent contract; and the transaction intelligent contract performs transaction processing according to the transaction information. The transaction volume can be improved.

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...
