Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating digital marks. One of the methods includes: obtaining entity information of an entity; transmitting the entity information to one or more nodes of a blockchain for storage in the blockchain; obtaining a transaction identification associated with storing the entity information in the blockchain; and generating a digital mark for the entity based at least on the transaction identification.

First claim

The invention claimed is:

1. A computer-implemented method, comprising:
obtaining, by one or more computer devices from a user device, entity information of an entity for registration;
transmitting, by the one or more computer devices, the entity information to one or more nodes of a blockchain for storage in the blockchain;
obtaining, by the one or more computer devices from the blockchain, a transaction identification of a blockchain transaction stored in the blockchain, wherein the blockchain transaction comprises the entity information, the transaction identification of the blockchain transaction indicates that the entity exists in the blockchain, and the transaction identification is queryable to retrieve the entity information from the blockchain;
generating, by the one or more computer devices for the entity, a digital mark that is uniquely identifiable based on the transaction identification;
transmitting, by the one or more computer devices, an association relationship between the generated digital mark and the entity to one or more nodes of the blockchain for storage in the blockchain; and
based on successful storage of the association relationship in the blockchain, returning, by the one or more computer devices, a success message of the registration to the user device.

2. The method of claim 1 , wherein:
the entity information comprises an identification number, an address, and contact information of the entity.

3. The method of claim 1 , wherein transmitting the entity information to the one or more nodes of the blockchain for storage in the blockchain comprises:
writing at least the entity information into a blockchain contract; and
causing the one or more nodes to initiate the blockchain transaction to deploy the blockchain contract and store the blockchain transaction to the blockchain.

4. The method of claim 1 , wherein:
the transaction identification is a hash value of the blockchain transaction.

5. The method of claim 1 , wherein:
the digital mark is a hash value of the blockchain transaction.

6. The method of claim 1 , wherein:
the entity is a corporation; and
the entity information comprises corporation registration information certified by an official agency.

7. The method of claim 1 , further comprising:
generating, by the one or more computer devices, a digital abstract of a digital certificate associated with the entity; and
associating the digital mark with the digital abstract of the digital certificate to represent the entity's endorsement of the digital certificate.

8. The method of claim 7 , further comprising:
transmitting, by the one or more computer devices, the digital abstract of the digital certificate to the one or more nodes of the blockchain for storage in the blockchain;
obtaining, by the one or more computer devices, a different transaction identification of a different blockchain transaction stored in the blockchain, the different blockchain transaction comprising the digital abstract of the digital certificate; and
associating, by the one or more computer devices, the digital mark with the different transaction identification.

9. The method of claim 8 , further comprising:
through a different association relationship, associating, by the one or more computer devices, the digital mark, the digital abstract of the digital certificate, and the different transaction identification of the different blockchain transaction stored in the blockchain.

10. The method of claim 9 , further comprising:
transmitting, by the one or more computer devices, the different association relationship to one or more nodes of the blockchain for storage in the blockchain.

11. A system, comprising one or more processors and one or more non-transitory computer-readable memories coupled to the one or more processors and configured with instructions executable by the one or more processors to cause the system to perform operations comprising:
obtaining, from a user device, entity information of an entity for registration;
transmitting the entity information to one or more nodes of a blockchain for storage in the blockchain;
obtaining, from the blockchain, a transaction identification of a blockchain transaction stored in the blockchain, wherein the blockchain transaction comprises the entity information, the transaction identification of the blockchain transaction indicates that the entity exists in the blockchain, and the transaction identification is queryable to retrieve the entity information from the blockchain;
generating, for the entity, a digital mark that is uniquely identifiable based on the transaction identification;
transmitting an association relationship between the generated digital mark and the entity to one or more nodes of the blockchain for storage in the blockchain; and
based on successful storage of the association relationship in the blockchain, returning a success message of the registration to the user device.

12. The system of claim 11 , wherein the operations further comprise:
generating a digital abstract of a digital certificate associated with the entity; and
associating the digital mark with the digital abstract of the digital certificate to represent the entity's endorsement of the digital certificate.

13. The system of claim 12 , wherein the operations further comprise:
transmitting the digital abstract of the digital certificate to the one or more nodes of the blockchain for storage in the blockchain;
obtaining a different transaction identification of a different blockchain transaction stored in the blockchain, the different blockchain transaction comprising the digital abstract of the digital certificate; and
associating the digital mark with the different transaction identification.

14. The system of claim 13 , wherein the operations further comprise:
through a different association relationship, associating the digital mark, the digital abstract of the digital certificate, and the different transaction identification of the different blockchain transaction stored in the blockchain.

15. The system of claim 14 , wherein the operations further comprise:
transmitting the different association relationship to one or more nodes of the blockchain for storage in the blockchain.

16. A non-transitory computer-readable storage medium configured with instructions executable by one or more processors to cause the one or more processors to perform operations comprising:
obtaining, from a user device, entity information of an entity for registration;
transmitting the entity information to one or more nodes of a blockchain for storage in the blockchain;
obtaining, from the blockchain, a transaction identification of a blockchain transaction stored in the blockchain, wherein the blockchain transaction comprises the entity information, the transaction identification of the blockchain transaction indicates that the entity exists in the blockchain, and the transaction identification is queryable to retrieve the entity information from the blockchain;
generating, for the entity, a digital mark that is uniquely identifiable based on the transaction identification;
transmitting an association relationship between the generated digital mark and the entity to one or more nodes of the blockchain for storage in the blockchain; and
based on successful storage of the association relationship in the blockchain, returning a success message of the registration to the user device.

17. The storage medium of claim 16 , wherein the operations further comprise:
generating a digital abstract of a digit
