The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, which shows a flowchart of a carbon asset management method provided in an embodiment of the present application, the carbon asset management method provided in an embodiment of the present application, applied to a block chain, may include:

s11: receiving identity information of each participant in advance, and generating an identity management contract according to the identity information; the identity management contract includes role permissions.

Firstly, in order to implement supervision on carbon resources, the identities of all participants on a blockchain need to be accurately defined, specifically, the blockchain may receive identity information of all participants in advance, and manage contracts according to the identity information of all participants and the identities corresponding to all the participants, so that each participant corresponds to one identity, that is, all the participants establish one identity on the blockchain. It should be noted that, in establishing the identity management contract, the blockchain may further receive a public key in a key pair generated by each participant, so as to generate the identity management contract according to the identity information of the participants and the public key in the corresponding key pair.

The participants mentioned here may specifically include:

1) the competent department responsible for platform management: appointing rules of issuance and transaction of carbon assets, managing emission reduction project parties (issuing, adjusting, canceling and receiving and paying quotas to emission reduction project parties, namely charging and discharging units), and holding parties (which can be understood as transaction parties);

2) emission reduction project side: the main administrative department of the supervised key emission unit distributes quota to the emission reduction project party, the emission reduction project party calculates whether the quota is enough according to the carbon emission condition of the emission reduction project party, the surplus quota can be sold, and the shortage enterprises need to purchase and complement the quota additionally;

3) carbon checking mechanism: the third-party checking mechanism subjected to supervision and authentication is responsible for checking the carbon emission amount of the emission reduction project party and issuing a third-party checking report for government approval;

4) the owner: enterprises or units participating in transactions can conduct transactions as long as registered subjects can conduct transactions, and holders need to have identities and can authorize other persons to conduct proxy transactions. The holder can carry out quota verification after purchasing carbon resources;

5) a third party trader: can proxy other people to trade carbon assets after being authorized;

6) the transaction center: the carbon assets can be established by a competent department and a trading medium (exchange), and only right transfer, order deposit and the like are carried out on the chain after the carbon assets complete trading in a trading center;

7) and (4) clearing a bank: and the payment channel is connected for clearing and settling funds.

In the present application, one identity is associated with a plurality of roles, each role corresponds to a series of role permissions, that is, each identity on the blockchain manages a group of roles, and has all associated role permissions (the generated identity management contract includes the corresponding role and role permissions). It should be noted that, since the present application is applicable to various service scenarios for carbon asset management, the basic role in the service is not limited, and besides the conventional basic role in the service, a role of a governing department is also defined, and the role of the governing department has a non-service authority for setting a role authority, that is, the governing department can manage the chain identities of the emission reduction project party, the carbon check organization, the holding party, or other participating parties.

The identity management contract is generated on the block chain in advance, so that the legality of the carbon asset can be confirmed by the identity management contract before the participation party participates in the carbon asset management, and the reliability and the accuracy of the carbon asset management are guaranteed.

S12: and receiving carbon emission data sent by the emission reduction project party, carrying out validity verification on the emission reduction project party according to the identity management contract, and writing the carbon emission data into the data verification contract if the carbon emission data passes the validity verification.

On the basis of the step S11, the blockchain may receive carbon emission data sent by the emission reduction project party, where the emission reduction project party may report the carbon emission data on line on a monthly basis (specifically, hash operation may be performed on the carbon emission data, and a result obtained by the hash operation is sent to the blockchain), and accordingly, the blockchain may receive the carbon emission data sent by the emission reduction project party on a monthly basis, and of course, a time interval for sending the carbon emission data may also be adjusted according to actual needs, which is not limited in this application. After receiving carbon emission data sent by an emission reduction project party, a block chain can search an identity management contract corresponding to the emission reduction project party from a pre-generated identity management contract, and judge whether the emission reduction project party meets role authority in the identity management contract corresponding to the emission reduction project party, specifically judge whether the operation of the emission reduction project party meets the requirement of the identity role authority corresponding to the emission reduction project party, namely carry out validity verification on the emission reduction project party, and write the carbon emission data into a data storage contract if the emission reduction project party passes the validity verification. The legality verification of the emission reduction project party by utilizing the pre-generated identity management contract can ensure that the emission reduction project party with the carbon emission data uplink qualification carries out the uplink of the carbon emission data, so that the reliability of the carbon emission data is ensured, and the reliability of the carbon asset management is conveniently ensured.

Through the process, the carbon emission data of the emission reduction project side can be stored in the block chain, so that the uniqueness, the non-tampering property and the permanent storage of the carbon emission data after chain linking are ensured by utilizing the non-tampering property and the traceability of the cross-link technology of the area, and the carbon emission data stored in the data certification contract can provide an accurate and reliable reference basis for carbon asset management.

S13: receiving carbon asset management information of a current participant, and judging whether the current participant has carbon asset management authority corresponding to the carbon asset management information according to an identity management contract; if yes, go to step S14.

When management of carbon assets is needed, the current participant may send carbon asset management information to the blockchain. After receiving the carbon asset management information of the current participant, the block chain may first search an identity management contract corresponding to the current participant from a pre-generated identity management contract, if the identity management contract corresponding to the current participant exists, determine whether the current participant has a carbon asset management authority corresponding to the carbon asset management information according to a role authority in the identity management contract corresponding to the current participant, if it is determined that the current participant has the carbon asset management authority corresponding to the carbon asset management information, execute step S14, and if it is determined that the current participant does not have the carbon asset management authority corresponding to the carbon asset management information, may refuse to perform carbon asset management in order to ensure reliability and accuracy of carbon asset management.

S14: and performing carbon asset management according to the data storage contract and the carbon asset management information.

If the current participant is determined to have the carbon asset management authority corresponding to the carbon asset management information, the blockchain can perform carbon asset management according to the data storage contract and the received carbon asset management information, namely, online carbon asset management is realized.

According to the process, the carbon assets can be converted into the digital assets through the method, chain management is achieved, the current participants are automatically authenticated and automatically managed on the block chain, a large amount of labor cost and material resource cost are avoided, the management efficiency and accuracy of the carbon assets are improved, and the supervision efficiency can be improved through online carbon asset management. In addition, a distributed, trusted and intelligent unified platform can be formed through block chain intervention.

According to the technical scheme disclosed by the application, an identity management contract is generated in advance according to identity information of each participant, wherein the identity management contract also comprises role deadlines, and carbon emission data of an emission reduction project party which passes through legality verification is written into a data certification contract of a block chain, so that uniqueness, non-tampering property and permanent storage after chaining of related data of carbon assets are ensured by using non-tampering and traceability of the block chain technology, and the identity management contract is used as a reliability basis for carbon asset management reference, when the carbon asset management information of the current participant is received, whether the current participant has a corresponding carbon asset management authority is judged according to the pre-generated identity management contract, and when the current participant is determined to have the corresponding carbon asset management authority, the block chain carries out carbon asset management according to the data certification contract and the carbon asset management information, the accuracy and the reliability of carbon asset management are improved, and the on-line carbon asset management is realized by managing the carbon assets on the block chain, so that the efficiency of the carbon asset management is improved, and the manpower and material resources consumed by the carbon asset management are reduced.

The carbon asset management method provided in the embodiment of the present application receives carbon asset management information of a current participant, and determines whether the current participant has a carbon asset management authority corresponding to the carbon asset management information according to an identity management contract, which may include:

receiving an identity contract address of a governing department, carbon asset information imported by the governing department and an identity contract address of an enterprise;

judging whether the administrative department meets the requirements of the carbon asset issuing rules or not according to the identity contract address and the identity management contract of the administrative department by using the service logic contract, and if so, determining that the administrative department has the authority of issuing the carbon assets;

performing carbon asset management according to the data certification contract and the carbon asset management information may include:

and determining whether the carbon asset information can be issued or not by using the resource contract, and if the carbon asset information can be issued, issuing the carbon asset information according to the data security contract and the identity contract address of the enterprise by using the resource contract.

In the application, when receiving carbon asset management information of a current participant and judging whether the current participant has a carbon asset management right corresponding to the carbon asset management information according to an identity management contract, after annual quota data of each enterprise imported by a specific administrative department, a blockchain may receive an identity contract address of the administrative department, carbon asset information imported by the administrative department, and an identity contract address of the enterprise, which are sent by a service system connected to the blockchain, wherein the administrative department manages an initial quota, a transaction quota, and a current quota of each organization, and specifically, a service logic contract in the blockchain may receive the identity contract address of the administrative department, the carbon asset information imported by the administrative department, and the identity contract address of the enterprise.

The business logic contract can realize basic operations of the digital assets, such as issuing, transferring, checking and selling of the carbon assets, and in order to realize management requirements of the carbon assets, the following design is carried out on the business logic contract:

first, business logic contracts need to interface with asset contracts. Before executing each specific operation defined in the business logic contract, the asset contract is required to be called to inquire whether the operation meets the requirement. If not, it cannot be successfully executed. If the requirements are met, the execution can be successful. The method comprises the following steps of recording basic information and balance information of a carbon asset in an asset contract, wherein the asset contract is designed as follows: the asset contract needs to interface with the business logic contract. The carbon asset limit issuing quantity, total issuing data, total checking and canceling data, attachment information and specific information of each account are recorded in the asset contract, and the specific information of each account comprises an account owner identity contract address, the account balance (specifically, the carbon asset balance) and a fragment address.

Second, business logic contracts require interfacing with identity management contract implementations. The method comprises the steps that a preset role authority is built in an identity management contract, when a service is called, a service logic contract initiates and calls the role authority of a participant identity management contract defined in the identity management contract, the service logic contract needs to judge whether the role authority corresponding to the identity management contract meets requirements or not, and after execution, a result is reported to an asset contract.

As can be seen from the above, after receiving the identity contract address of the governing department, the carbon asset information imported by the governing department and the identity contract address of the enterprise, the block chain can use the service logic contract to call and acquire the identity management contract corresponding to the administrative department according to the identity contract address of the administrative department and the pre-generated identity management contract, and acquiring the role authority in the identity management contract corresponding to the administrative department, judging whether the administrative department meets the requirement of a preset carbon asset issuing rule or not according to the role authority in the identity management contract corresponding to the administrative department, namely judging that the role authority in the identity management contract corresponding to the administrative department meets the requirement of the preset carbon asset issuing rule, and if the administrative department meets the requirement of the carbon asset issuing rule, determining that the administrative department has the authority for issuing the carbon asset. The validity of carbon asset issuing of a competent department can be ensured by using a pre-generated identity management contract to judge whether the competent department meets the requirements of preset carbon asset issuing rules or not, so that the reliability and the accuracy of carbon asset issuing are improved.

On the basis, when carbon asset management is performed according to a data underwriting contract and carbon asset management information, an asset contract can be called, the carbon asset information is firstly checked by using the asset contract, whether the carbon asset information can be issued is judged, if the carbon asset information can be issued, the carbon asset information is issued according to an identity contract address of an enterprise by using the asset contract with the data underwriting contract as a reference, that is, the carbon asset information is correspondingly saved in the asset contract according to the identity contract address of the enterprise and the asset contract itself (for example, an account balance corresponding to the enterprise can be calculated according to the identity contract of the enterprise, carbon emission data corresponding to the enterprise in the data underwriting contract and carbon asset information corresponding to the enterprise, which is introduced by a management department, and the account balance corresponding to the enterprise is saved in the contract asset of the enterprise) so as to realize the uplink of the carbon asset, and particularly, refer to fig. 2, which shows a schematic diagram of carbon asset release provided by an embodiment of the present application.

The intelligent contracts in the block chains can be utilized to realize the carbon assets being issued on the chains through the process, so that the issuing efficiency of the carbon assets is ensured, the issued carbon asset information can be prevented from being subsequently tampered and counterfeited randomly, the accuracy and the reliability of the carbon asset information are ensured, and the carbon asset information can be traced, accountable and supervised by issuing the carbon assets on the chains.

The carbon asset management method provided in the embodiment of the present application receives carbon asset management information of a current participant, and determines whether the current participant has a carbon asset management authority corresponding to the carbon asset management information according to an identity management contract, which may include:

receiving identity information and carbon asset transaction information of both trading parties, and judging whether both trading parties have carbon asset transaction authority or not by using a business logic contract according to the identity information and the identity management contract of both trading parties;

performing carbon asset management according to the data certification contract and the carbon asset management information may include:

and judging whether the carbon asset transaction information is correct or not by using the asset contract according to the data evidence contract, and if so, carrying out transfer planning on the carbon assets corresponding to both parties in the transaction in the asset contract according to the carbon asset transaction information.

In the method, when the carbon asset management information of the current participant is received and whether the current participant has the carbon asset management right corresponding to the carbon asset management information is judged according to the identity management contract, after the holder initiates a carbon asset transaction, the blockchain can receive the identity information and the carbon asset information of both parties of the transaction, which are sent by a business system connected with the holder. Specifically, the business system can send the identity information of both transaction parties and the carbon asset information to business logic contracts in a block chain, search the identity management contracts respectively corresponding to both transaction parties according to the identity information of both transaction parties and the pre-generated identity management contracts by using the business logic contracts, call role authorities in the identity management contracts respectively corresponding to both transaction parties, judge whether both transaction parties have carbon asset transaction authorities according to the role authorities in the identity management contracts respectively corresponding to both transaction parties, and execute subsequent operations when both transaction parties are confirmed to have the carbon asset transaction authorities so as to guarantee the legality and accuracy of carbon asset transaction and guarantee the authenticity and accuracy of carbon asset data stored on the block chain.
