Abstract

A computer-implemented method includes: receiving, by a platform including one or more computing devices, a blockchain authorization information generation request from a client, in which the blockchain authorization information generation request includes a target blockchain identifier and user information; determining, based on the target blockchain identifier, a target blockchain; determining a blockchain parameter of the target blockchain, in which the blockchain parameter indicates one or more requirements for authorization information used to join the target blockchain; generating blockchain authorization information based on the blockchain parameter and the user information, in which the blockchain authorization information conforms to the one or more requirements; and sending the blockchain authorization information to the client.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
receiving, from a client device by a platform comprising one or more computing devices, a request to become a blockchain node in a target blockchain, wherein the request comprises a target blockchain identifier and user information;
identifying, by the platform, based on the target blockchain identifier, the target blockchain;
determining, by the platform, a blockchain parameter of the target blockchain, wherein the blockchain parameter indicates one or more requirements for authorization information to satisfy the request to become a blockchain node in the target blockchain;
selecting, by the platform, a password generation algorithm, wherein an output of the password generation algorithm conforms to the one or more requirements;
generating, by the platform and using the password generation algorithm, blockchain authorization information based on the blockchain parameter and the user information, wherein the blockchain authorization information comprises a blockchain identity certificate; and
sending the generated blockchain authorization information to at least one of the client device or an administrator of the target blockchain.

2. The computer-implemented method of claim 1 , wherein generating the blockchain authorization information comprises:
generating a blockchain identity certificate request based on the user information by using the password generation algorithm;
sending the blockchain identity certificate request to an authentication server for signature authentication;
receiving, from the authentication server, a signature-authenticated blockchain identity certificate request; and
using the signature-authenticated blockchain identity certificate request as the blockchain identity certificate.

3. The computer-implemented method of claim 1 , wherein generating the blockchain authorization information comprises:
generating a blockchain identity certificate request based on the user information by using the password generation algorithm;
sending the blockchain identity certificate request to the administrator of the target blockchain;
receiving, from an authentication server, a signature-authenticated blockchain identity certificate request, subsequent to the administrator approving the blockchain identity certificate request and sending the blockchain identity certificate request to the authentication server; and
using the signature-authenticated blockchain identity certificate request as the blockchain identity certificate.

4. The computer-implemented method of claim 1 , wherein the blockchain authorization information comprises a private key, and wherein generating the blockchain authorization information comprises:
generating the private key based on the user information by using the password generation algorithm.

5. The computer-implemented method of claim 1 , wherein the one or more requirements comprise one or more of: a key format, a type of encryption algorithm used to generate the blockchain authorization information, or a type of user information to be included in the blockchain authorization information.

6. The computer-implemented method of claim 1 , wherein the blockchain parameter of the target blockchain is stored locally at the platform.

7. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
receiving, from a client device by a platform comprising one or more computing devices, a request to become a blockchain node in a target blockchain, wherein the request comprises a target blockchain identifier and user information;
identifying, by the platform, based on the target blockchain identifier, the target blockchain;
determining, by the platform, a blockchain parameter of the target blockchain, wherein the blockchain parameter indicates one or more requirements for authorization information to satisfy the request to become a blockchain node in the target blockchain;
selecting, by the platform, a password generation algorithm, wherein an output of the password generation algorithm conforms to the one or more requirements;
generating, by the platform and using the password generation algorithm, blockchain authorization information based on the blockchain parameter and the user information, wherein the blockchain authorization information comprises a blockchain identity certificate; and
sending the generated blockchain authorization information to at least one of the client device or an administrator of the target blockchain.

8. The computer-readable medium of claim 7 , wherein generating the blockchain authorization information comprises:
generating a blockchain identity certificate request based on the user information by using the password generation algorithm;
sending the blockchain identity certificate request to an authentication server for signature authentication;
receiving, from the authentication server, a signature-authenticated blockchain identity certificate request; and
using the signature-authenticated blockchain identity certificate request as the blockchain identity certificate.

9. The computer-readable medium of claim 7 , wherein generating the blockchain authorization information comprises:
generating a blockchain identity certificate request based on the user information by using the password generation algorithm;
sending the blockchain identity certificate request to the administrator of the target blockchain;
receiving, from an authentication server, a signature-authenticated blockchain identity certificate request, subsequent to the administrator approving the blockchain identity certificate request and sending the blockchain identity certificate request to the authentication server; and
using the signature-authenticated blockchain identity certificate request as the blockchain identity certificate.

10. The computer-readable medium of claim 7 , wherein the blockchain authorization information comprises a private key, and wherein generating the blockchain authorization information comprises:
generating the private key based on the user information by using the password generation algorithm.

11. The computer-readable medium of claim 7 , wherein the one or more requirements comprise one or more of: a key format, a type of encryption algorithm used to generate the blockchain authorization information, or a type of user information to be included in the blockchain authorization information.

12. The computer-readable medium of claim 7 , wherein the blockchain parameter of the target blockchain is stored locally at the platform.

13. 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, cause the one or more computers to perform one or more operations comprising:
receiving, from a client device by a platform comprising one or more computing devices, a request to become a blockchain node in a target blockchain, wherein the request comprises a target blockchain identifier and user information;
identifying, by the platform, based on the target blockchain identifier, the target blockchain;
determining, by the platform, a blockchain parameter of the target blockchain, wherein the blockchain parameter indicates one or more requirements for authorization information to satisfy the request to become a blockchain node in the target blockchain;
selecting, by the platform, a password generatio
