[0045] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in the specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0047] Figure 1 The flowchart of the blockchain-based certificate evaluation method provided in the embodiment of this specification. Figure 1 As shown, a blockchain-based certificate evaluation method provided by the present application includes the following steps:

[0048] S101, the blockchain node obtains the certificate information of the certificate issued by the certification authority, as well as the owner information of each certificate.

[0049] In this application specification, the above-mentioned blockchain is a blockchain network, and the blockchain network can be pre-built. The above-mentioned blockchain node can correspond to a certification agency; it can also correspond to a relevant third-party entity, and the third-party entity mentioned here can be a government agency or a corresponding supervisory agency.

[0050] The above-mentioned certification bodies can be official certification bodies, such as the State Intellectual Property Office that issues patent certificates; they can also be some unofficial institutions with certification qualifications.

[0051] In some embodiments of the present application, the certificate information includes at least one of the following: certificate name, certificate issuance time, issuing authority name, and certificate owner name. The certificate information mentioned here may refer to part or all of the information contained in the issued certificate.

[0052] The certificate owner information at least includes: the industry in which the certificate owner is engaged. For example, a certificate holder is engaged in food production, or a certificate holder is engaged in refrigerator production. When the certificate owner is an individual, the industry in which the certificate owner is engaged can be determined based on the certificate owner's work; when the certificate owner is an individual, the industry in which the certificate owner is engaged can be determined based on the products the certificate owner operates.

[0053] In this application description, the certificate owner information may include not only the industry in which the certificate owner is engaged, but also the identity of the certificate owner. For example, when the certificate owner is an individual, his / her identity is his / her ID card number; when the certificate owner is a company, his / her identity is his / her business license number,

[0054] S102, writing the certificate information and the information of each certificate owner into the blockchain for storage.

[0055] The blockchain node writes the obtained certificate information and the information of each certificate owner into the blockchain, which can save the above information on the one hand, and effectively prevent the above information from being tampered with on the other hand, thereby enhancing the security of the above information. Furthermore, the certificate can be verified based on the certificate information and the information of each certificate owner stored in the blockchain to determine the authenticity of the certificate and avoid the use of fake certificates to satisfy improper interests.

[0056] S103: Determine the type of each certificate according to the certificate name in the above certificate information.

[0057] In this application specification, certificates with the same certificate name may be regarded as certificates of the same type. For example, a certificate with the certificate name of "Motor Vehicle Driving License" may be regarded as a certificate of the same type.

[0058] In addition, certificates of the same type may have different certificate names. For example, if the certificate type is an intellectual property certificate, a computer software copyright registration certificate, a utility model patent certificate, and a trademark registration certificate may be used as certificates of the same type.

[0059] It should be noted that step S103 may be executed before S102 or after S102, which is not limited in the embodiments of the present application.

[0060] In the embodiment of the present application, the determination of the certificate type can be independently set according to the needs of the user and is not limited to the above method.

[0061] S104, obtaining certificate information of the same type of certificates and information of each certificate owner stored in the blockchain.

[0062] After step S103 is executed, the blockchain node can obtain the certificate information of the same type of certificates and the information of each certificate owner from the blockchain.

[0063] S105, based on the certificate information of the same type of certificates and the information of the owners of each certificate, the certificate is evaluated to obtain an evaluation result of the certificate of this type.

[0064] In some embodiments of the present application, the evaluation result includes at least one of the following: the number of certificates of this type held, and the number of certificates of this type held in various industries.

[0065] In some embodiments of the present application, the number of certificates of the same type held can be determined by calculating the number of certificates of the same type in the acquired blockchain.

[0066] It is also possible to determine the type of industry that the certificate owner is engaged in based on the industry that the certificate owner is engaged in. And based on the type of industry that the certificate owner is engaged in, calculate the number of certificates of this type held in each industry type, that is, the number of certificates held in each industry.

[0067] It should be noted that the type of industry that the certificate owner is engaged in can be determined based on the industry that the certificate owner is engaged in. For example, if the industry type is vehicle manufacturing, then the certificate owners who manufacture bicycles, electric vehicles, and cars are of the same industry type.

[0068] In addition, in the embodiment of the present application, the classification of the industry types that the certificate owner is engaged in can be independently set according to the needs of the user and is not limited to the above method.

[0069] In some embodiments of the present application, the certificate is evaluated based on the certificate information of the same type of certificates and the information of the owner of each certificate, and the evaluation result is obtained based on the smart contract deployed on the blockchain. The smart contract mentioned here is pre-deployed on the blockchain. Through the smart contract, on the one hand, all parties can be informed of the evaluation rules for the certificate, and on the other hand, tampering with the evaluation method can be avoided to cause errors in the evaluation results.

[0070] S106, writing the evaluation result of the certificate of this type into the blockchain for storage.

[0071] Writing the evaluation results of the certificate into the blockchain can prevent the evaluation results from being maliciously tampered with and ensure the authenticity of the certificate evaluation.

[0072] In some embodiments of the present application, a blockchain-based integrin evaluation method provided in the embodiments of the present application may also include:

[0073] receiving a query request from an external terminal, wherein the query request includes a certificate name;

[0074] According to the certificate name, query the corresponding evaluation result stored in the blockchain;

[0075] The evaluation result is fed back to the external terminal so that the external terminal can display the received evaluation result to the corresponding user.

[0076] Through the above method, it is convenient for other users to query the evaluation results and evaluate the value of the certificate based on the evaluation results.

[0077] The embodiment of the present application provides a blockchain-based certificate evaluation method, which evaluates the same type of certificates through the certificate information and certificate owner information stored in the blockchain, and writes the evaluation results into the blockchain. Through this technical solution, on the one hand, it can prevent the relevant information of the certificate (certificate information and certificate owner information) and the certificate evaluation results from being tampered with, and ensure the authenticity of the data; on the other hand, it can be used as a reference for the value evaluation of the certificate, giving full play to the role of the certificate to obtain the corresponding value; finally, the authenticity of the certificate can also be verified to avoid the loss of corresponding interests due to fake certificates.
