The trusted node is typically a government department with legal authority and the jurisdiction of the government department matches the corresponding business scope of the product. In addition, the trusted node may or may not be a node on the blockchain.
In order to ensure the credibility of the credible nodes, in the embodiment of the present application, intelligent contracts are deployed on each node of the blockchain. The method is set in an intelligent contract, and the triggering condition is that trusted node application messages with the number larger than a threshold value are received, and the trusted node application messages comprise: and applying for credible qualification of the nodes. And when the contract is set to be executed, determining the application nodes with the credible qualifications meeting the preset value, and initiating voting aiming at the determined application nodes. The new qualification may be used to indicate the trustworthiness or legal authority of the trusted node.
In the embodiment of the present application, the block chain query information includes: and inquiring target identification and inquiring condition data. The query target identifier may be product name, trademark, product image, manufacturer name, production place information, and other information related to the product. The query condition data may be a keyword, a sentence or a template, for example, whether the information of the a device is really on the chain, wherein "the information of the a device" is the query target identifier, and "x has green environment qualification" is the query condition.
In order to prevent the business secret of an enterprise from being leaked, in the embodiment of the application, secret-related identification is added into data of a chain by each enterprise node on a zone-crossing chain, so that whether first information carries the secret-related data identification or not is determined by a trusted node, and then corresponding prompt information is returned to a user terminal by the trusted node when the first information carries the secret-related data identification, and the user is informed that the information cannot be inquired about when secret-related data identification is carried by the trusted node.
And step 104, the trusted node converts the first information into second information according to a preset information conversion template.
In addition to general questions such as whether the information is on a chain or qualified, the user may also query specific product attribute questions such as product composition, texture, etc. Therefore, the product attribute problem needs to be converted for different products, for example, the structural data of the product needs to be converted for the appliance class, and the classification data needs to be converted for the daily chemical class. In order to improve the conversion accuracy, in the embodiment of the application, a plurality of information conversion templates are arranged in a node in advance, each conversion template corresponds to a product type, the trusted node determines the information conversion template according to the product type in the query condition data, and then converts the first information into the second information according to the determined information conversion template.

In the embodiment of the application, the trusted node displays the second information in one or more of characters, voice and images at the display terminal.
In the embodiment of the application, in order to confirm and check the information sent by the trusted node, the trusted node writes the second information into the block, so that the whole chain node agrees with the second information. And the identification of the block is sent to the user, so that the user can find the second information on the corresponding block, thereby proving the authenticity of the second information. In fact, some users may not know enough about the blockchain to quickly find the second information by using the identification of the block, and in order to solve the above problem, in this embodiment of the present application, the user may send verification information to a node of the blockchain other than the trusted node, where the verification information includes: identification of the block and second information. And the node of the block chain verifies whether the second information exists or not by using the information in the corresponding block according to the identification of the block, and returns a verification result to the user.
