Abstract

This specification describes techniques for managing assets in a blockchain. One example method includes receiving, from a target user recorded in a distributed database of a blockchain network, a user input including a request to transfer a plurality of asset objects including digital assets corresponding to physical assets associated with the target user, in response to receiving the request, combining the plurality of asset objects in a target object, the target object including an address field used to maintain address information of the plurality of asset objects, deleting address information corresponding to the plurality of asset objects from the target object, and adding the address information to asset receiving objects corresponding to the plurality of asset objects.

Claims

1. A computer-implemented method for asset management, the method comprising:

receiving, from a target user recorded in a distributed database of a blockchain network, a user input comprising a request to transfer a plurality of asset objects comprising digital assets corresponding to physical assets associated with the target user;

in response to receiving the request, combining the plurality of asset objects in a target object, the target object comprising an address field used to maintain address information of the plurality of asset objects;

deleting address information corresponding to the plurality of asset objects from the target object; and

adding the address information to asset receiving objects corresponding to the plurality of asset objects.

2. The computer-implemented method of claim 1, wherein the request comprises an asset type specified by the target user.

3. The computer-implemented method of claim 2, further comprising deploying a contract object corresponding to the asset type in the blockchain network to create the target object.

4. The computer-implemented method of claim 3, wherein the contract object comprises an execution program configured to generate the asset object and a code field that is used to maintain an execution code related to the execution program.

5. The computer-implemented method of claim 1, wherein the blockchain network comprises a consortium chain, and the target user in the blockchain network is a consortium member that has asset object generation authority in the consortium chain.

6. The computer-implemented method of claim 1, further comprising:

determining whether the request satisfies a predetermined transfer rule; and

in response to determining that the request satisfies the predetermined transfer rule, deleting the address information from the target object and adding the address information to an asset receiving object that corresponds to the asset object.

7. The computer-implemented method of claim 1, further comprising generating for the target user a public key associated with an account address of an institution in the blockchain network and a private key configured to be used by the institution to operate the account.

8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

receiving, from a target user recorded in a distributed database of a blockchain network, a user input comprising a request to transfer a plurality of asset objects comprising digital assets corresponding to physical assets associated with the target user;

in response to receiving the request, combining the plurality of asset objects in a target object, the target object comprising an address field used to maintain address information of the plurality of asset objects;

deleting address information corresponding to the plurality of asset objects from the target object; and

adding the address information to asset receiving objects corresponding to the plurality of asset objects.

9. The non-transitory, computer-readable medium of claim 8, wherein the request comprises an asset type specified by the target user.

10. The non-transitory, computer-readable medium of claim 9, wherein the operations further comprise deploying a contract object corresponding to the asset type in the blockchain network to create the target object.

11. The non-transitory, computer-readable medium of claim 10, wherein the contract object comprises an execution program configured to generate the asset object and a code field that is used to maintain an execution code related to the execution program.

12. The non-transitory, computer-readable medium of claim 8, wherein the blockchain network comprises a consortium chain, and the target user in the blockchain network is a consortium member that has asset object generation authority in the consortium chain.

13. The non-transitory, computer-readable medium of claim 8, wherein the operations further comprise:

determining whether the request satisfies a predetermined transfer rule; and

in response to determining that the request satisfies the predetermined transfer rule, deleting the address information from the target object and adding the address information to an asset receiving object that corresponds to the asset object.

14. The non-transitory, computer-readable medium of claim 8, wherein the operations further comprise generating for the target user a public key associated with an account address of an institution in the blockchain network and a private key configured to be used by the institution to operate the account.

15. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising;

receiving, from a target user recorded in a distributed database of a blockchain network, a user input comprising a request to transfer a plurality of asset objects comprising digital assets corresponding to physical assets associated with the target user;

in response to receiving the request, combining the plurality of asset objects in a target object, the target object comprising an address field used to maintain address information of the plurality of asset objects;

deleting address information corresponding to the plurality of asset objects from the target object; and

adding the address information to asset receiving objects corresponding to the plurality of asset objects.

16. The computer-implemented system of claim 15, wherein the request comprises an asset type specified by the target user.

17. The computer-implemented system of claim 16, wherein the operations further comprise deploying a contract object corresponding to the asset type in the blockchain network to create the target object.

18. The computer-implemented system of claim 17, wherein the contract object comprises an execution program configured to generate the asset object and a code field that is used to maintain an execution code related to the execution program.

19. The computer-implemented system of claim 15, wherein the blockchain network comprises a consortium chain, and the target user in the blockchain network is a consortium member that has asset object generation authority in the consortium chain.

20. The computer-implemented system of claim 15, wherein the operations further comprise:

determining whether the request satisfies a predetermined transfer rule;

in response to determining that the request satisfies the predetermined transfer rule, deleting the address information from the target object and adding the address information to an asset receiving object that corresponds to the asset object; and

generating for the target user a public key associated with an account address of an institution in the blockchain network and a private key configured to be used by the institution to operate the account.
