Step 2: and uploading related filing files on the platform by the project owner, and initiating a check voluntary volume reduction filing application. And respectively auditing other nodes on the alliance chain. After each node passes the audit and signs the endorsement by a private key, the platform automatically signs and issues the electronic version of the underwriting certificate to voluntarily reduce the discharge capacity; specifically, the step 2 includes the following steps: step 2.1: and uploading the filing file on the platform by the project owner, signing the file by using a private key, and simultaneously initiating a check voluntary volume reduction filing application. The platform processes the File, wherein the processing mode comprises calculating a File Hash value, uploading the File to a distributed File System (preferably, an inter-platform File System, an inter-satellite File System) to obtain a File URL and the like, and then uploading the File Hash value and the File URL to a chain for storage; step 2.2: after the other nodes on the alliance chain synchronize data, the public key of the project owner is used for verifying the file, and the file is guaranteed not to be tampered in the transmission process. Then the node accesses the file URL to download the filing file, and independently checks the filing file; step 2.3: and (4) the intelligent contract initiates on-chain voting, and if a certain node passes the auditing, the node applies for a vote for filing. If the nodes except the project owner approve the tickets, the platform automatically issues electronic edition approval voluntary emission reduction (the denomination is in tons) to the project owner, and online registration authority of the approval voluntary emission reduction is completed, so that the approval voluntary emission reduction is mapped into the digital assets which can be split and circulated on the block chain. After the endorsement result and the issuing information are added with a credible time stamp (preferably provided by a national time service center), the certificate is credibly stored on the block chain platform.
And 3, step 3: and the issued certificate voluntarily reduces the discharge amount to enter the platform resource pool.
And 4, step 4: after the emission control enterprise publishes the emission reduction purchase demand on the platform, the platform automatically matches and matches the purchase demand with the CER in the resource pool. If the matching can not be realized, the system splits or merges the existing core evidence voluntarily reduced discharge capacity in the resource pool to meet the matching requirement; specifically, the step 4 includes the following steps: step 4.1: a discharge control enterprise (a power plant, an iron and steel plant and the like) issues a discharge reduction purchase demand (in tons) on a platform; and 4.2: the platform automatically matches and matches the purchase demand with the voluntary emission reduction of the approval in the resource pool; step 4.3: if the matching is successful, entering step 5; if the situation that accurate matching cannot be achieved occurs, the platform can split or combine the existing nuclear evidence voluntarily reduced displacement in the resource pool. Splitting refers to splitting a CER with a large single reduced volume amount into a plurality of CERs with a small amount (or splitting a single CER into reference CERs with multiple denominations of 1 ton); merging refers to merging multiple smaller displacement amount CERs into one larger amount CER. The newly generated core certificate voluntarily reduces the displacement and records the ownership mapping relation of the original CER, and records the certificate on the block chain.
And 5: after the transaction matching is successful, the intelligent contract on the block chain obtains the real-time carbon price through an external Oracle (Oracle) and calculates the transaction price, and after the purchaser confirms the transaction signature and pays, the ownership of the CER is automatically transferred to the purchaser to complete the transaction circulation. Specifically, the step 5 includes the following steps: step 5.1: the intelligent contract on the block chain sends a real-time carbon price query request to an out-of-chain language prediction machine (Oracle); step 5.2: after receiving the request, the Oracle (Oracle) queries the real-time trading unit price (in tons) of the national carbon market through an external trusted data source (preferably, shanghai environmental energy exchange), and feeds back the query result to the intelligent contract; step 5.3: the intelligent contract automatically calculates the transaction price according to the purchase quantity and the unit price and sends the transaction price to the buyer. After the buyer confirms the signature through the private key, the intelligent contract automatically initiates deduction. After the owner (seller) confirms the collection of the money, the rights of CER are automatically transferred to the buyer, and the rights change and transaction process are linked to the credit card all the time.
