The character "/" generally indicates that the context-dependent object is an "or" relationship.
The technical scheme of the embodiment of the application relates to the technical field of block chains, and before the technical scheme of the embodiment of the application is introduced, the block chain technology is simply introduced.
Blockchain (Blockchain): a distributed account book in the field of information technology is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. Blockchains are essentially a de-centralized database, which is a series of data blocks (i.e., blocks) that are generated in association using cryptographic methods, each of which contains information from a batch of network transactions for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer. Common mechanisms include, but are not limited to, POW (Proof of Work), POS (Proof of equity), DPOS (shared Proof of-of-stane consistence), PBFT (Practical Byzantine Fault Tolerance, practical bayer fault tolerance protocol), and the like.
As above, a blockchain is essentially a de-centralized database, and the blockchain is commonly maintained by nodes in the blockchain network, which are the smallest units involved in blockchain maintenance, and which are the deployment and execution units for the blockchain point program. For example, referring to FIG. 1, in the blockchain network 10 shown in FIG. 1, a plurality of nodes 101 may be included. Each node 101 may receive input information while operating normally and maintain shared data within the blockchain network based on the received input information. In order to ensure information intercommunication in the blockchain network, information connection can exist between every two nodes in the blockchain network, and information transmission can be carried out between the nodes through the information connection. For example, when any node in the blockchain network receives input information, other nodes in the blockchain network acquire the input information according to a consensus algorithm, and store the input information as shared data, so that the data stored on all the nodes in the blockchain network are consistent. The blocks are commonly known through nodes, so that the blocks have the characteristics of non-falsification, traceability, common maintenance and the like.
For each node in the blockchain network, there is a node identification corresponding thereto, and each node in the blockchain network may store the node identifications of other nodes for subsequent broadcasting of the generated blocks to other nodes in the blockchain network based on the node identifications of the other nodes. Each node can maintain a node identification list, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol interconnecting between networks) address, or any other information that can be used to identify the node.
Each node in the blockchain network stores one and the same blockchain. Referring to fig. 2, the blockchain is composed of a plurality of blocks, the starting block includes a block header and a block body, the block header stores input information characteristic values, version numbers, time stamps, difficulty values and the like, and the block body stores input information; the next block of the starting block takes the starting block as a father block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value, the version number, the timestamp, the difficulty value and the like of the father block, and the like, so that the block data stored in each block in the block chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.
It is understood that each node in the blockchain network may be a server or a terminal. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a Cloud server providing Cloud services, cloud databases, cloud Computing (Cloud Computing), cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network ), basic Cloud Computing services such as big data and intelligent platform. The terminal may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a terminal used in an automobile, an aircraft, and the like. The nodes may be directly or indirectly connected through wired or wireless communication, and the present application is not limited herein.
The technical scheme of the embodiment of the application relates to a block chain technology, and is described in detail as follows:
in the related technology, the carbon transaction flows of different transaction parties are disordered, unified standards are not formed, and a trust mechanism is lacked, so that the reliability and the safety of the carbon transaction are low. Based on the above, the embodiment of the application provides a data processing method and device based on a blockchain, electronic equipment, a storage medium and a program product, which can improve the credibility and the safety of carbon transaction.
Referring to fig. 3, fig. 3 is a schematic diagram of an implementation environment according to the present application, where the implementation environment includes a transaction initiator 310, a transaction processor 320, and a blockchain network 330, where the transaction initiator 310 and the transaction processor 320 may communicate through a wired or wireless network, and the blockchain network includes a plurality of blockchain nodes 331, and the blockchain nodes 331 may communicate through a wired or wireless network. Transaction handler 320 may be any blockchain node in blockchain network 330, or the transaction handler may be a server or terminal capable of communicating with blockchain node 331. The transaction initiator 310 may be a server or a terminal, and specific examples of the server and the terminal are referred to in the foregoing description, and are not repeated herein.
The blockchain network includes a plurality of carbon accounts, and each carbon account is used for recording information of carbon resources held by a carbon resource holding object to which the carbon account belongs, for example, carbon resource holding amount and the like. Transaction initiator 310 may initiate a carbon resource transaction request for a carbon resource to transaction processor 320. The transaction processor 320 receives a carbon resource transaction request, searches a resource transfer-out carbon account and a resource transfer-in carbon account corresponding to the carbon resource transaction request from a plurality of carbon accounts contained in the blockchain network 330, and obtains a transaction carbon resource for transaction from a plurality of carbon resources contained in the resource transfer-out carbon account, then calculates a resource difference between a carbon resource amount of the transaction carbon resource and a carbon resource transaction amount corresponding to the carbon resource transaction request, splits the transaction carbon resource into a first carbon resource containing carbon resource with an amount matching the resource difference, and a second carbon resource containing carbon resource with an amount matching the carbon resource transaction amount, wherein the first carbon resource and the second carbon resource contain identification information of the transaction carbon resource; then, updating transaction carbon resources contained in the resource transfer-out carbon account into first carbon resources, and updating second carbon resources to the resource transfer-in account so as to complete carbon resource transaction; and then, generating a carbon resource transaction record corresponding to the carbon resource transaction request, and storing the carbon resource transaction record into a blockchain network, wherein the carbon resource transaction record comprises identification information of transaction carbon resources, a carbon account into which the resources are transferred, and carbon resource amounts respectively contained in the transaction carbon resources, the first carbon resources and the second carbon resources. In the whole transaction process, on one hand, storage of carbon resource information and transaction of carbon resources are realized through a blockchain technology, so that the transparency and the safety of the transaction are improved based on the characteristics of tamper resistance, traceability, common maintenance and the like of the blockchain technology; on the other hand, the output carbon resource (i.e., the first carbon resource and the second carbon resource) of each carbon resource transaction contains the identification information of the input carbon resource (i.e., the transaction carbon resource), and a carbon resource transaction record containing the identification information of the input carbon resource is generated, so that all carbon resource transaction records of the carbon resource can be traced based on the identification information of the carbon resource, traceability of the carbon resource transaction is realized, supervision of the carbon resource is facilitated, and the transaction safety is further improved.
It should be noted that, in the present application, data related to a carbon resource holding object, such as a carbon account, a carbon resource amount, etc., is obtained or agreed by the carbon resource holding object when the method of the present application is applied to a specific product or technology, and extraction, use and processing of the related data all comply with local safety standards and regulations of local laws and regulations.
Referring to fig. 4, fig. 4 is a flowchart illustrating a blockchain-based data processing method according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 3, which may be performed by the transaction processor 320 in the implementation environment shown in fig. 3. As shown in FIG. 4, in an exemplary embodiment, the blockchain-based data processing method may include steps S410-S440, described in detail below:
step S410, searching a resource transfer-out carbon account and a resource transfer-in carbon account corresponding to the received carbon resource transaction request from a plurality of carbon accounts contained in the blockchain network, and acquiring transaction carbon resources for transaction from a plurality of carbon resources contained in the resource transfer-out carbon account.
The carbon resource refers to a resource related to the emission amount of greenhouse gases such as carbon dioxide, and can be used for transactions. For example, to effectively control emissions of room gases such as carbon dioxide, reduce greenhouse gas emissions for individuals and businesses, for individuals, convert low carbon behavior into carbon emissions, trading media (e.g., carbon credits, etc.) available for trading, etc., which can be used to purchase goods, redeem carbon credits, etc.; for businesses, trading media or carbon quotas may be purchased from individuals or other businesses; correspondingly, the carbon resource includes, but is not limited to, at least one of carbon emissions, trading media such as carbon credits, and the like. The carbon quota refers to a greenhouse gas emission reduction index which is required to be completed according to regulations, and can be set by related departments.
In order to realize the trusted transaction of the carbon resource, a carbon account is arranged in the blockchain network and is used for recording the information of the carbon resource held by the carbon resource holder. Carbon resource holders include, but are not limited to, individuals, businesses, related departments, etc. that can register with a blockchain network to obtain carbon accounts. The information of the carbon resource includes, but is not limited to, the amount of the carbon resource contained in the carbon resource, identification information of the carbon resource, and the like, and the identification information of the carbon resource includes, but is not limited to, the identification number of the carbon resource. Each carbon account can contain multiple carbon resources, each carbon resource contains the corresponding carbon resource amount and identification information, and the carbon resource amounts contained by different carbon resources can be equal or unequal.
If the transaction of the carbon resource is required, the transaction initiator may initiate a carbon resource transaction request for the carbon resource, where the transaction request may include transaction information such as carbon account information (resource transfer-out carbon account, resource transfer-in carbon account) of both transaction parties, and transaction amount of the carbon resource. The resource transfer-out carbon account is a carbon account of a carbon resource transfer-out party, and the resource transfer-in carbon account is a carbon account of a carbon resource transfer-in party, that is, carbon resources contained in the resource transfer-out carbon account need to be transferred to the resource transfer-in carbon account. The carbon resource trade volume is the number of carbon resources that need to be traded, i.e., the number of carbon resources that need to be transferred from the resource transfer-out carbon account to the resource transfer-in carbon account.
After receiving the carbon resource transaction request, the transaction processor can search a resource transfer-out carbon account and a resource transfer-in carbon account from a plurality of carbon accounts contained in the blockchain network according to the carbon account information of both transaction sides contained in the carbon resource transaction request, and acquire transaction carbon resources for transaction from a plurality of carbon resources contained in the resource transfer-out carbon account.
Optionally, in the process of acquiring the information of the transaction carbon resources for the transaction included in the resource transfer-out carbon account, at least one carbon resource with the sum of the carbon resource amounts matched with the transaction amount of the carbon resources is screened out from the multiple carbon resources included in the resource transfer-out carbon account, and then the screened at least one carbon resource is used as the transaction carbon resource for the transaction. Wherein, to ensure that the transaction can be successfully performed, matching the sum of the amounts of carbon resources contained in the at least one carbon resource with the transaction amount of carbon resources may mean that the sum of the amounts of carbon resources contained in the at least one carbon resource is greater than or equal to the transaction amount of carbon resources. The specific manner of screening out at least one carbon resource, in which the sum of the amounts of the carbon resources contained in the plurality of carbon resources contained in the carbon account transferred from the resource matches the transaction amount of the carbon resource, may be flexibly set according to actual needs, including but not limited to: firstly, randomly transferring out a plurality of carbon resources contained in a carbon account from the resource to obtain the carbon resource until the sum of the carbon resource amounts contained in the obtained carbon resource is matched with the carbon resource transaction amount; second, carbon resources are acquired from a plurality of carbon resources contained in the carbon account transferred from the resources according to a specified sequence until the sum of the carbon resource amounts contained in the acquired carbon resources is matched with the carbon resource transaction amount, wherein the specified sequence may be a sequence from large to small in the carbon resource amount contained, a sequence from small to large in the carbon resource amount contained, a sequence from front to back in the carbon resource generation time (or update time), a sequence from back to front in the carbon resource generation time (or update time), and the like.
S420, calculating the resource difference between the carbon resource amount of the transaction carbon resource and the carbon resource transaction amount corresponding to the carbon resource transaction request, and splitting the transaction carbon resource into a first carbon resource with the carbon resource amount matched with the resource difference and a second carbon resource with the carbon resource amount matched with the carbon resource transaction amount; wherein the first carbon resource and the second carbon resource comprise identification information of the transaction carbon resource.
In order to transfer the carbon resources matched with the carbon resource transaction amount to the carbon account, the resource difference between the carbon resource amount of the transaction carbon resources and the carbon resource transaction amount can be calculated, and then the transaction carbon resources contained in the carbon account of the resource transfer are split into first carbon resources and second carbon resources, wherein the carbon resources contained in the first carbon resources are matched with the resource difference, and the carbon resources contained in the second carbon resources are matched with the carbon resource transaction amount, that is, the first carbon resources are the residual carbon resources of the transaction carbon resources after the carbon resources matched with the carbon resource transaction amount are transferred from the transaction carbon resources to the carbon account.
In order to determine the source of the first carbon resource and the second carbon resource, thereby facilitating subsequent traceability, the first carbon resource and the second carbon resource further comprise identification information of the transaction carbon resource.
Alternatively, in some embodiments, the resource transfer-out carbon account contains multiple carbon resources, and the corresponding transaction carbon resource may contain one or more carbon resources. If the transaction carbon resource contains one part of carbon resource, the transaction carbon resource can be directly split into two parts of carbon resource in the splitting process, wherein one part is used as the first carbon resource, and the other part is used as the second carbon resource. If the transaction carbon resource contains multiple carbon resources, in the splitting process, determining the carbon resource to be split and other carbon resources except the carbon resource to be split from the multiple carbon resources contained in the transaction carbon resource, and splitting the carbon resource to be split to obtain one carbon resource matched with the resource difference and another carbon resource, so that the sum of the carbon resource contained in the other carbon resource and the carbon resource contained in the other carbon resource is matched with the carbon resource transaction amount, and taking the other carbon resource and the other carbon resource as a second carbon resource and taking the carbon resource matched with the resource difference obtained by splitting as a first carbon resource.
Alternatively, in some scenarios, multiple carbon resources may be involved in the carbon resource trading process, for example, an individual may include carbon credits, where the enterprise needs carbon emission reduction, in the process of purchasing a commodity sold by the enterprise, for an individual carbon account, a carbon resource is turned out to be carbon credits, and for an enterprise carbon account, a carbon resource is turned into be carbon emission reduction, under the condition, calculating a resource difference between a carbon resource amount of the trading carbon resource and a carbon resource trading amount corresponding to the carbon resource trading request, and splitting the trading carbon resource into a first carbon resource including a carbon resource amount matching the resource difference, and a second carbon resource including a carbon resource amount matching the carbon resource trading amount may include: determining a transfer-out resource type and a transfer-in resource type according to a transaction request, if the transfer-out resource type is different from the transfer-in resource type, acquiring transaction carbon resources with the type matched with the transfer-out resource type from a resource transfer-out account, converting the transaction carbon resources into intermediate carbon resources with the type matched with the transfer-in resource type, and splitting the intermediate carbon resources into first carbon resources and second carbon resources according to the carbon resource transaction amount, wherein the carbon resource amount of the first carbon resources is matched with the resource difference (the difference between the carbon resource amount of the intermediate carbon resources and the carbon resource transaction amount), the carbon resource amount of the second carbon resources is matched with the carbon resource transaction amount, and optionally, the first carbon resources and the second carbon resources can contain identification information of the transaction carbon resources, or the first carbon resources and the second carbon resources can contain identification information of the intermediate carbon resources. For example, assuming that the carbon resource contained in the personal carbon account is carbon deposit, the carbon resource contained in the enterprise carbon account is carbon reduction amount, 1000 carbon deposit can be converted into 20 kg carbon reduction amount, 2 kg carbon reduction amount is needed in the enterprise carbon account 1, and 18 kg carbon reduction amount is needed in the enterprise carbon account 2, in the transaction process, 1000 carbon deposit can be converted into 20 kg carbon reduction amount from the carbon deposit contained in the personal carbon account, and then 20 kg carbon reduction amount is divided into 2 kg carbon reduction amount and 18 kg carbon reduction amount, and the two carbon reduction amounts are respectively updated to the enterprise carbon account 1 and the enterprise carbon account 2, wherein the 2 kg carbon reduction amount and the 18 kg carbon reduction amount can contain identification information of 20 kg carbon reduction amount or identification information of 1000 carbon deposit.
S430, updating the transaction carbon resources contained in the resource transfer-out carbon account to the first carbon resources, and updating the second carbon resources to the resource transfer-in account.
After the first carbon resource and the second carbon resource are obtained, the transaction carbon resource contained in the resource transfer-out carbon account is updated to the first carbon resource, and the second carbon resource is updated to the resource transfer-in carbon account, so that the carbon resource matched with the carbon resource transaction amount is transferred from the resource transfer-out carbon account to the resource transfer-in carbon account. That is, the first carbon resource is the balance of the transaction carbon resource after the transaction, and the second carbon resource is the resource which needs to be transferred to the carbon account. For example, assuming that the carbon resource is a carbon emission amount, the carbon resource transaction amount is 15 kg, and the resource transfer-out carbon account contains 20 kg of carbon resource a, after the transaction, the resource transfer-out carbon account contains 5 kg of carbon resource identified as a, and 15 kg of carbon resource identified as a is added to the resource transfer-out carbon account.
Optionally, if the carbon resource amount of the transaction carbon resource is equal to the carbon resource transaction amount, the carbon resource amount of the first carbon resource is 0, and in a process of updating the transaction carbon resource included in the resource transfer-out carbon account to the first carbon resource, the transaction carbon resource included in the resource transfer-out carbon account may be directly deleted without updating the first carbon resource to the resource transfer-out carbon account.
It should be noted that, if the carbon account in which the resource is transferred includes a plurality of resources, the transaction carbon resource needs to be split into a first carbon resource and a second carbon resource corresponding to each carbon account in which the resource is transferred. The carbon resource amount contained in the second carbon resource is matched with the carbon resource amount required to be transferred by the corresponding resource transferred into the carbon account.
S440, generating a carbon resource transaction record corresponding to the carbon resource transaction request, and storing the carbon resource transaction record to the blockchain network; the carbon resource transaction record comprises identification information of transaction carbon resources, a carbon account into which the resources are transferred, and carbon resource amounts respectively contained in the transaction carbon resources, the first carbon resources and the second carbon resources.
After the transaction carbon resources contained in the resource transfer-out carbon account are updated to the first carbon resources and the second carbon resources are updated to the resource transfer-in account, a carbon resource transaction record corresponding to the carbon resource transaction request can be generated and stored in the blockchain network, so that the transaction data can be traced.
The carbon resource transaction record includes, but is not limited to, a carbon account into which a resource is transferred, and carbon resource amounts respectively included in the transaction carbon resource, the first carbon resource, and the second carbon resource, and the carbon resource transaction record may further include a carbon account into which a resource is transferred. The specific form of the carbon resource transaction record can be flexibly set according to actual needs, and optionally, a UTXO (Unspent Transaction Output, unconsumed transaction output) mode can be adopted to generate the carbon resource transaction record corresponding to the carbon resource transaction request. It should be noted that UTXOs are a record keeping method in a blockchain system, each transaction has several transaction inputs, that is, a resource source, and several transaction outputs, that is, a resource destination, and the generated output is "unexpired transaction output", that is, UTXOs. For the transaction of carbon resources, the transaction input is a transaction carbon resource, the transaction output is a first carbon resource and a second carbon resource, and the transaction record of the carbon resources comprises the transaction input, the transaction output and identification information of the carbon resources corresponding to the transaction input. For example, assuming that the transaction 1001 corresponding to the first carbon resource transaction request needs to transfer a carbon resource with a carbon resource amount of 5 from carbon account a to carbon account B, carbon account a contains a carbon resource with a carbon resource amount of 18, see table 1 below, and the carbon resource transaction record includes a transaction input (carbon resource amount of 18, carbon resource 1 belonging to carbon account a), a transaction output (carbon resource amount of 13, carbon resource 2 belonging to carbon account a, carbon resource amount of 5, carbon resource 3 belonging to carbon account B), and identification information of carbon resource 1; the transaction 1002 corresponding to the second carbon resource transaction request is that carbon resources with carbon resource amount of 2 need to be transferred from carbon account B to carbon account C, and carbon resources with carbon resource amount of 3 need to be transferred from carbon account B to carbon account D, and then, as shown in table 2 below, the carbon resource transaction record includes transaction input (carbon resource amount of 5, carbon resource 3 with carbon account of carbon account B), transaction output (carbon resource amount of 2, carbon resource 4 with carbon account of carbon account C, carbon resource amount of 3, carbon resource 6 with carbon account of carbon account D), and identification information of carbon resource 3.

The method may be applied to the implementation environment shown in fig. 3, which may be performed by the transaction processor 320 in the implementation environment shown in fig. 3. As shown in fig. 5, the method includes steps S410-S440, and steps S510-S530, which are described in detail as follows:
step S510, acquiring carbon behavior data, and searching a carbon account to which the carbon behavior data belongs from a plurality of carbon accounts.
The carbon behavior refers to behaviors related to reducing the emission of greenhouse gases such as carbon dioxide, including but not limited to low-carbon travel behaviors such as walking, riding bicycles, riding public transportation means, and the like, network office behaviors for reducing travel such as online ticket purchasing, online payment, online reservation, and the like, and behaviors for reducing paper and plastic use such as paperless reading, electronic invoice, and the like. Carbon behavior data refers to data related to carbon behavior, including but not limited to, the category of carbon behavior, time of occurrence, number of times, etc., such as number of athletic steps, number of public transportation rides, number of electronic invoices, and the like.
To encourage low carbon life, etc., the carbon behavioral data may be converted into carbon resources for trade, thereby allowing the carbon behavioral subjects to benefit. After the carbon behavior data is obtained, a carbon account to which the carbon behavior data belongs may be searched from a plurality of carbon accounts contained in the blockchain network.
Optionally, after the carbon behavior data is obtained and the carbon account to which the carbon behavior data belongs is searched from the plurality of carbon accounts, the carbon account may be verified, for example, whether the registration information included in the carbon account is true, whether the carbon account is authenticated by a real name, whether the carbon account has authority to generate a carbon point, and the like, and after the verification is successful, step S520 is performed again.

Alternatively, the carbon resource amount to be charged corresponding to the carbon behavior data may be calculated according to the conversion parameter between the carbon emission reduction amount and the carbon resource and the carbon emission reduction amount corresponding to the carbon behavior data, for example, assuming that the carbon resource is carbon integral, reducing the emission by 1 gram of carbon dioxide may obtain 10 integral, and if the carbon emission reduction amount corresponding to the carbon behavior data is 2 grams, the carbon resource amount to be charged is 20 integral. The specific mode of calculating the carbon emission reduction amount according to the carbon behavior data can be flexibly set according to actual needs, and optionally, in order to unify the calculation mode of the carbon emission reduction amount, the transparency and the reliability of the carbon emission reduction amount are improved, and the blockchain intelligent contract can be called to calculate the carbon emission reduction amount.

And then, storing the generated carbon resource generation record into a blockchain network, so that the traceability of the carbon resource is facilitated.
To enable trusted generation of carbon resources, in an alternative embodiment, a blockchain smart contract may be invoked and steps S520-S530 are implemented by the blockchain smart contract.
Optionally, the carbon resource generation record may further include identification information (e.g., hash value) of the carbon resource generation record, where the carbon resource to be checked may include identification information of the carbon resource generation record, in a transaction process of the carbon resource, identification information of the carbon resource generation record included in the input carbon resource may be added to the output carbon resource, so that tracing of the carbon behavior data may be performed based on the identification information of the carbon resource generation record included in the carbon resource, for example, assuming that the hash value of the carbon resource transaction record is hash1 generated based on the carbon behavior data, the carbon resource a1 includes hash1, in a certain carbon resource transaction process, the carbon resource a1 is split into carbon resource a2 and carbon resource a3, and in another carbon resource transaction process, the carbon resource a3 is split into carbon resource a4 and carbon resource a5, and then the carbon resources a2-a5 each include hash1, so that the original source hash1 included in the carbon resource a5 may be directly searched for, and the carbon behavior data of the original source can be traced.

In an exemplary embodiment, referring to fig. 10, fig. 10 is a flowchart illustrating a blockchain-based data processing method according to another exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 3, which may be performed by the transaction processor 320 in the implementation environment shown in fig. 3. As shown in fig. 10, the blockchain-based data processing method includes S410-S440 and S1010-S1040 under the condition that the carbon account further includes a carbon quota, wherein the detailed description of steps S1010-S1040 is as follows:
step S1010, acquiring a carbon resource conversion request, and searching a resource conversion carbon account and a designated carbon account from a plurality of carbon accounts according to the carbon resource conversion request; wherein the carbon resource conversion request contains a carbon resource conversion amount.
In some scenarios, the carbon account may contain a carbon quota, where the carbon resource needs to be converted into a carbon quota, for example, for an enterprise, a related department may allocate a carbon quota index to be completed for the enterprise, the enterprise needs to implement the carbon quota index, and if the enterprise cannot implement the carbon quota index, the carbon resource held by the enterprise may be converted into a carbon quota, thereby completing the carbon quota index.
The designated carbon account contained in the blockchain network refers to an account for managing carbon quotas, which may be applied by a related department registered in the blockchain network.
If conversion between carbon resources and carbon configuration is required, a carbon resource conversion request may be initiated, where the carbon resource conversion request includes information of a carbon account required to perform carbon resource conversion and a carbon resource conversion amount (the number of carbon resources required to be converted).
After the carbon resource conversion request is obtained, the resource conversion carbon account and the designated carbon account can be searched from a plurality of carbon accounts contained in the blockchain network.
