Problems solved by technology

However, there are still many problems in my country's carbon emission trading market. Under the traditional carbon trading model, problems such as information asymmetry, data opacity, and lack of trust mechanism have caused both parties to the transaction to spend more energy on investigation. The amount is negotiated, and the transaction process is cumbersome, which slows down the transaction efficiency

Embodiment 1

[0084] In step S7, if the seller publishes auction information, the steps are as follows:

[0085] Step S71: the platoon-controlled enterprise as the seller invokes the auction contract to release auction information, wherein the auction information includes: auction quota, starting price, and auction duration;

[0086] Step S72: The platoon-controlled enterprise as the buyer invokes the auction contract to sign up for the auction;

[0087] Step S73: The buyers and sellers participating in the auction conduct the auction transaction through the off-chain ad hoc network, and the buyer organizes a transaction amount including the timestamp, the transaction serial number txNum, and the bid amount, signs it with its own private key SK_buyer, and sends it to the seller;

[0088] Step S74: If the seller approves the bid after receiving the transaction, it signs the transaction and broadcasts it to all buyers;

[0089] Step S75: After the other buyers receive the broadcast, if they ...

Abstract

The invention discloses a carbon emission transaction method based on a block chain, and the method employs an open, transparent and traceable block chain technology, combines with an intelligent contract, enables a traditional carbon emission transaction process to be linked, and builds a data sharing platform. An under-chain auction mode is adopted in the enterprise quota transaction link, a buyer signs a transaction containing bidding amount, a previous transaction hash value and other information and then sends the transaction to a seller, the seller signs the transaction and then broadcasts the transaction to other buyers, the other buyers continue to bid on the basis of the price and send the transaction to the seller, the process is repeated, and the transaction is completed. And the auction time is ended. The method has the advantages that the method is based on a block chain system, a data sharing platform is established, all transactions are open, transparency and openness of the whole carbon transaction process are greatly enhanced, traceability of carbon transaction data is also realized, and the method is suitable for popularization and application. And the joint data fraud behavior of the enterprise and the third-party mechanism caused by information asymmetry between the enterprise and the local government is prevented.

Description

technical field [0001] The invention relates to the technical fields of carbon emission trading and blockchain, and in particular, to a blockchain-based carbon emission trading platform. Background technique [0002] As the world's largest carbon emitter, China is actively establishing a carbon trading market, and plans to achieve carbon peaking by 2030 and carbon neutrality by 2060. Since the National Development and Reform Commission of China approved the establishment of pilot carbon emission trading markets in seven provinces and cities including Beijing and Shanghai in November 2011, the carbon trading volume has increased year by year, and the construction of my country's carbon trading market is gradually improving. However, there are still many problems in my country's carbon emissions trading market. Under the traditional carbon trading model, problems such as information asymmetry, data opacity, and lack of trust mechanisms cause both parties to spend more energy t...
