Description

Technical Field

[0001] The present invention belongs to the fields of carbon assets, blockchain, and token technology, and in particular relates to a carbon asset tokenization system. Background Art

[0002] Carbon assets refer to carbon quotas issued by government departments, carbon sinks obtained by enterprises through methodology, and carbon quotas or carbon sinks obtained through transactions.

[0003] Currently, carbon asset trading is mainly handled by over-the-counter brokers. There is no complete trading market, resulting in a lack of transparency, no centralized pricing or availability data source, and a long cycle for the entire transaction process. Summary of the invention

[0004] In view of the shortcomings and gaps in the existing technology, the purpose of the present invention is to provide a carbon asset tokenization system, which tokenizes carbon assets through a carbon bridge. In view of the potential problems of carbon credit trading, the present invention aims to tokenize carbon assets and open up two-way circulation of carbon assets on and off the chain, which is conducive to improving the liquidity of carbon assets, facilitating relevant participants to trade directly on the chain, and to a certain extent improving transparency and transaction efficiency, while also reducing transaction fees.

[0005] The token contract program used is deployed on the blockchain system. The blockchain system is a network system, and it is a distributed point-to-point network system. In such a network system, there is a consensus mechanism. In this network, each piece of data has ownership, and this ownership is identified by a key called a private key. The person who owns the private key owns the corresponding data. The entire ownership will be verified by the entire network through the consensus mechanism. The data with ownership generated in this mechanism is a token, an ownership that is verified and recognized by most nodes in the network.

[0006] The present invention specifically adopts the following technical solutions:

[0007] A carbon asset tokenization system, characterized in that it is deployed on a blockchain system and includes: a token contract program consisting of a carbon asset blockchain and a token blockchain connected by a carbon bridge;

[0008] The carbon asset blockchain records relevant information about carbon quotas and carbon sinks;

[0009] The carbon bridge is used to migrate carbon assets from the carbon quota blockchain and the carbon sink blockchain to the token blockchain.

[0010] Furthermore, the specific method of migrating carbon assets from the carbon asset blockchain to the token blockchain through the carbon bridge is to first create an NFT on the carbon bridge, and then delete the asset from the carbon asset blockchain to achieve the transfer of assets:

[0011] First, by setting up a reference-id, a link channel between NFT and carbon assets is established on the carbon bridge.

[0012] Transfer the information of carbon assets to NFT through the serial number of carbon assets;

[0013] Before submitting the NFT to the token smart contract, the blockchain verifies the release of carbon assets and checks the status of the NFT.

[0014] Furthermore, the carbon bridge allows users to convert carbon assets into non-fungible tokens, which retain information including the source, type, and year of the carbon assets; after the conversion, the carbon quota blockchain and the carbon sink blockchain cancel the converted carbon assets; by transferring tokens into the carbon pool, users obtain homogeneous currency tokens for transactions.

[0015] Furthermore, the carbon asset blockchain specifically records:

[0016] Carbon quota description, including: unified social credit code, allocation method, allocation unit, asset serial number, carbon tonnage, year, location, type;

[0017] Carbon sink description, including: methodology, asset serial number, project name, year, location, carbon tonnage.

[0018] Furthermore, the tokenization process of carbon assets specifically includes the following steps:

[0019] Step S1: Create an NFT with reference-id on Carbon Bridge. Reference-id contains the token blockchain id and the hash value of this transaction, which is used to link with carbon asset information. The initial number of NFTs is 0.

[0020] Step S2: Add reference-id to the carbon asset information for linking with the NFT on the carbon bridge;

[0021] Step S3: Establish a two-way link channel between the carbon bridge and the carbon asset blockchain, and the NFT on the carbon bridge is linked to the carbon asset blockchain;

[0022] Step S4: On the carbon bridge, the NFT is updated with the help of the serial number of the carbon asset, and the project information of the carbon sink is retrieved from the carbon asset blockchain and attached to the NFT;

[0023] Step S5: Delete the target carbon asset serial number and related project information on the carbon asset blockchain, and Carbon Bridge disconnects the link with the carbon asset blockchain;

[0024] Step S6: Carbon Bridge confirms whether the carbon asset has been correctly released from the carbon asset blockchain and whether the NFT has been changed to the agreed release state;

[0025] Step S7: After the verification is passed, Carbon Bridge disconnects the link with the carbon asset blockchain; if the verification fails, it rechecks and rolls back the relevant information and returns to step S1;

[0026] Step S8: Carbon Bridge automatically submits the NFT to the smart contract of the token blockchain;

[0027] Step S9: Tokenize NFT through smart contracts.

[0028] Compared with the prior art, the key design points of the present invention and its preferred solution include:

[0029] 1. Proposed the design of smart carbon bridge

[0030] Through the carbon bridge, carbon assets are migrated from the carbon asset blockchain to the token blockchain. The asset transfer is achieved by first establishing NFT on the carbon bridge and then deleting the assets from the carbon asset blockchain.

[0031] 2. Proposed a carbon asset tokenization architecture

[0032] A carbon asset tokenization architecture based on carbon bridge is proposed, which allows multiple carbon asset blockchains to tokenize carbon assets through carbon bridge. This architecture can correctly transfer carbon assets from carbon asset blockchain to token blockchain.

[0033] 3. Establish the connection between NFT and carbon assets

[0034] By setting up a reference-id, a link channel between NFT and carbon assets is established on the carbon bridge.

[0035] 4. Transfer the information of carbon assets to NFT through serial numbers

[0036] The information of carbon assets is transferred to NFT through the serial number of carbon assets.

[0037] 5. Verify the release status of carbon assets and check the NFT status before submitting for tokenization

[0038] Before submitting the NFT to the token smart contract, the blockchain verifies the release of carbon assets and checks the status of the NFT.

[0039] Through a complete tokenization process, the correct execution of carbon asset tokenization is guaranteed.

[0040] In the scheme, Carbon Bridge allows users to convert carbon assets into non-homogeneous tokens, which will retain information such as the source, type, and year of the carbon assets. After the conversion, the carbon quota blockchain and the carbon sink blockchain will cancel the converted carbon assets. By transferring tokens to the carbon pool, users can obtain homogeneous currency tokens for trading, and companies that need carbon credits for compliance can directly use these carbon credits to offset their own carbon emissions.

[0041] Carbon Bridge can put carbon assets on the chain. The actual value of a token can be anchored to the cost of neutralizing one ton of carbon dioxide. By putting carbon assets on the chain, these emission reduction projects can be funded and encouraged to generate more carbon assets. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figure 1 As shown, in this embodiment, the carbon assets and carbon bridges are described as follows:

[0048] (1) Description of carbon assets

[0049] Carbon assets include carbon quotas and carbon sinks.

[0050] Carbon quota description: unified social credit code, allocation method, allocation unit, asset serial number, carbon tonnage, year, location, type.

[0051] Carbon sink description: methodology, asset serial number, project name, year, location, carbon tonnage.

[0052] (2) Carbon bridge

[0053] Through the carbon bridge, carbon assets are migrated from the carbon quota blockchain and carbon sink blockchain to the token blockchain.

[0054] (3) Token blockchain

[0055] The migration destination of carbon assets.

[0056] like Figure 2 As shown, in the solution provided in this embodiment, the tokenization process of carbon assets is specifically as follows:

[0057] (1) Create an NFT with a reference-id

[0058] Create an NFT on Carbon Bridge with a reference-id. The reference-id contains the token blockchain id and the hash value of this transaction. The initial quantity of the NFT is 0.

[0059] Note: NFT, the full name of which is Non-Fungible Token, refers to non-fungible tokens. It is a unique cryptocurrency token used to represent digital assets (including jpg and video clips) and can be bought and sold.

[0060] reference-id, used to link with carbon asset information.

[0061] (2) Carbon asset information plus reference-id

[0062] The carbon asset information plus the reference-id is used to link with the NFT on the carbon bridge.

[0063] (3) Establishment of a two-way link channel and linking of Carbon Bridge NFT to the carbon asset blockchain

[0064] A two-way link channel is established between the Carbon Bridge and the carbon asset blockchain, and the NFT on the Carbon Bridge is linked to the carbon asset blockchain.

[0065] (4) Update NFT

[0066] On the Carbon Bridge, the NFT is updated with the help of the serial number of the carbon asset, and the project information of the carbon sink is retrieved from the carbon asset blockchain and attached to the NFT.

[0067] (5) Deleting relevant information about carbon assets on the blockchain

[0068] Delete the carbon asset serial number and related project information on the carbon asset blockchain, and disconnect the Carbon Bridge from the carbon asset blockchain.

[0069] (6) Carbon Bridge verifies the release of carbon assets and checks the status of NFTs

[0070] Carbon Bridge confirms whether the carbon assets have been correctly released from the carbon asset blockchain and whether the NFT has been changed to the agreed release state.

[0071] (7) Verification passed

[0072] Carbon Bridge disconnects from the Carbon Assets blockchain.

[0073] (8) Submit NFT

[0074] CarbonBridge automatically submits NFTs to the smart contract of the token blockchain.

[0075] (9) NFT Tokenization

[0076] Tokenize NFT through smart contracts.

[0077] (10) Verification failed

[0078] If the verification fails, recheck and roll back the relevant information.

[0079] like Figure 3 The following is an example of the current carbon quota allocation method. The meaning of carbon sink can generally be considered to include:

[0080] (1) Forestry carbon sinks:

[0081] The process, activity or mechanism of absorbing carbon dioxide from the atmosphere through afforestation, reforestation and forest management, reducing deforestation and other activities and combining them with carbon sink trading.

[0082] (2) Forest carbon sinks:

[0083] Forest carbon sink refers to the process by which forest plants absorb carbon dioxide from the atmosphere through photosynthesis and fix it in vegetation and soil, thereby reducing the concentration of carbon dioxide in the atmosphere. Forests are the largest carbon pool in the terrestrial ecological carbon sink system and play a unique role in reducing the concentration of greenhouse gases in the atmosphere and slowing down global warming.

[0084] Although forests only account for one-third of the total land area, the carbon storage in forest vegetation areas accounts for almost half of the total land carbon pool. Relevant data show that every cubic meter of forest growth can absorb about 1.83 tons of carbon dioxide and release 1.62 tons of oxygen.

[0085] (3) Grassland carbon sink:

[0086] Grassland carbon sinks mainly fix the absorbed carbon dioxide in the soil underground. Compared with forests, grassland ecosystems have lower carbon storage. For a long time, my country's grasslands have been disturbed by overgrazing, reclamation and human activities, the vegetation cycle has changed rapidly, and the accumulation of surface litter is relatively small.

[0087] Perennial herbaceous plants have a relatively stronger carbon sequestration capacity. With the implementation of my country's project of returning farmland to forest and grassland, the carbon sequestration increase of degraded grasslands is more obvious, so the carbon sequestration function of grasslands can be fully utilized.

[0088] (4) Cultivated land carbon sink:

[0089] Carbon sequestration in cultivated land only involves the part of carbon sequestration by returning crop straw to the fields. The reason is that the food produced on cultivated land is consumed every year, and the fixed carbon dioxide in it is emitted into the atmosphere. Part of the straw is used as fuel in rural areas, and only the part used as agricultural organic fertilizer fixes carbon dioxide in the soil of cultivated land.

[0090] (5) Marine carbon sinks:

[0091] Marine carbon sink is the process and mechanism of the ocean as a specific carrier to absorb carbon dioxide from the atmosphere and fix it. More than half of the biocarbon and green carbon on the earth is captured by marine organisms such as plankton, bacteria, seaweed, salt marsh plants and mangroves. The amount of biological carbon fixation per unit sea area is 10 times that of forests and 290 times that of grasslands.

[0092] (6) Artificial carbon sinks:

[0093] Carbon negative technology (CCS) that captures carbon dioxide released from the burning of fossil fuels and biomass and stores it underground, or reuses it (CCUS).

[0094] This patent is not limited to the above-mentioned optimal implementation method. Anyone can derive other forms of carbon asset tokenization systems based on the inspiration of this patent. All equivalent changes and modifications made within the scope of the patent application of the present invention should be covered by this patent.
