In order to solve the above-mentioned problems, the embodiment of the present application provides a transaction method of industry information as shown in fig. 4. The proposed method can be applied to an industry information transaction system shown in fig. 1, which includes 1 server and terminal devices respectively corresponding to a plurality of registered enterprises, and which is used for industry information transaction of a first industry (for example, vehicle industry). Referring to fig. 3, the trade method of industry information provided in the embodiment of the application includes, but is not limited to, steps S301 to S305. Possible implementations of this embodiment of the method are described further below. The first enterprise may refer to a terminal device corresponding to the first enterprise.

S301, a first enterprise sends a registration request message to a server, and the server receives the registration request message sent by the first enterprise, wherein the registration request message comprises certificate information, a service type, a resource type and a demand type.

It will be appreciated that if the first business wants to transact business information with a registered business in the business information transaction system 100, first, the first business needs to register an account in the business information transaction system 100 to acquire the qualification of transacting business information with the registered business in the business information transaction system 100.

Specifically, the first enterprise sends a registration request message to the server, and the server receives the registration request message sent by the first enterprise, where the registration request is used to acquire qualification of performing industry information transaction with the enterprise in the industry information transaction system. The registration request message includes credential information for the first enterprise, one or more business types for the first enterprise, one or more resource types for the first enterprise, and one or more demand types for the first enterprise. The certificate information is used by the server to qualify the registration request message, and in the event that the qualification passes, the resource type and the demand type are used by a plurality of registered enterprises in the system to qualify the registration request message.

In embodiments of the present application, the credential information may include a related credential, certificate, and/or proof of the first enterprise, such as a business license, tax registration certificate, scanned piece of organization code certificate, and so forth. The business type is a classification of different business to be processed in each industry, for example, the first business is involved in the related business of vehicle sales, and the business type involved in the first business may include vehicle sales, vehicle maintenance, vehicle insurance, and the like. The resource type may be a classification of the different types of industry information that the business may provide, for example, the resource type of the first business may include vehicle diagnostic data, demand sales information, repair shop reverse flow information, and so on. The demand type is a classification of the different industry information required by the business, for example, the demand type of the first business may include car insurance information, demand maintenance data, driving behavior data, and the like.

Optionally, the server and the first enterprise are each block link point devices. The industry information transaction system periodically selects a node from the block link points in the blockchain-based industry information transaction system to implement the function of a management node (i.e., server). After each period starts, the management node of the period is selected by a plurality of blockchain nodes through the existing consensus mechanism, wherein the consensus mechanism can be a practical Bayesian fault tolerance algorithm (English: practical Byzantine Fault Tolerance, english abbreviation: PBFT) or a Raft protocol consensus mechanism, and the application is not limited to the above.

S302, triggering a first intelligent contract to conduct qualification examination according to the certificate information corresponding to the first enterprise by the server, wherein the first intelligent contract is used for restricting registration conditions of the enterprise.

An intelligent contract is a computer protocol that aims to propagate, verify, or execute contracts in an informative manner. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible. The purpose of smart contracts is to provide a secure transaction method and reduce other transaction costs associated with the contract.

In the embodiment of the application, a first enterprise sends a registration request message to a server, and after the server receives the registration request message, the server judges whether certificate information of the first enterprise in the registration request message meets a first intelligent contract. If so, the server passes the qualification screening of the first enterprise. For example, the first industry is the vehicle industry, and the first smart contract includes a first condition that the certificate information of the enterprise needs to include a "quality management system certificate".

S303, if the examination is passed, the server sends a registration request message to a plurality of registered enterprises.

Optionally, if the examination passes, the server sends a registration request message to M registered enterprises, where N registered enterprises exist in the industry transaction system, N is a positive integer, and M is a positive integer greater than zero and less than or equal to N.

Optionally, the server sends the service type of the first enterprise, the resource type of the first enterprise and the requirement type of the first enterprise in the registration request message to the M registered enterprises.

In the embodiment of the present application, the server selects M enterprises from the N enterprises to send the registration request message, where the selection manner may be random selection or may be selection according to a preset selection policy, which is not specifically limited in the present application. If M is equal to N, the server directly sends registration request elimination to the N enterprises.

S304, each enterprise in the plurality of registered enterprises carries out registration voting on the registration request of the first enterprise according to the service type, the resource type and the requirement type in the registration request message.

Optionally, the registered enterprise judges the correlation between the first enterprise and the first industry according to the service type of the first enterprise in the registration request message, judges whether the first enterprise has value to the industry information transaction system according to the resource type and the demand type of the first enterprise, and performs registration voting on the registration request of the first enterprise according to the judging results of the two judgments. The method is not limited to the above two judging modes, and in the embodiment of the present application, the registration voting may be performed on the registration request of the first enterprise according to other modes, which is not particularly limited in the embodiment of the present application. For example, the registered enterprises can evaluate the authenticity of the service type, the resource type and the requirement type of the first enterprise in the registration request message according to the existing information, and perform registration voting according to the evaluation result.

S305, each enterprise in the plurality of registered enterprises sends a registration vote to a server, and the server receives the registration vote sent by each enterprise in the plurality of registered enterprises.

Alternatively, the registration voting choices may include endorsements, anti-endorsements, and outages, and the registration voting results for the plurality of registered enterprises may be proportional to the endorsements counted by the registration votes for each enterprise. For example, 7 out of 10 votes from registered businesses are endorsed, 2 anti-votes and 1 disuse vote, and the endorsed proportion is 70%. Alternatively, the registered voting options are in favor of a proportion, the voting options including 0, 40%, 80% and 100%, and the registered voting results of 10 registered enterprises may be in favor of an average of the registered voting statistics of each enterprise.

S306, if the proportion of the voting results of the registered enterprises exceeds a first preset threshold, the server passes through the registration request of the first enterprise and sends a registration response message to the first enterprise.

Optionally, after the server passes through the registration request message, the server records the publicable information in the registration request message into the blockchain, and all enterprises in the industry information transaction system based on the blockchain can review and supervise the publicable information.
