In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, the step S10 includes:
step S11, obtaining activity information in the activity request;
step S12, determining the production and management activity participants in the activity information, wherein the production and management activity participants comprise an initiator, a receiver and an activity supervisor of the production and management activity;
in this embodiment, when a node in the blockchain initiates an activity request, the blockchain platform obtains activity information in the activity request. The activity information includes a production and management activity participant, the production and management activity participant includes an initiator, a receiver and an activity manager of the production and management activity, for example, when the activity request is a transaction request, the transaction bill in the transaction request may include contents of transaction generation time, order number, commodity name, commodity quantity, commodity unit price, transaction amount, transaction state, supplier information, buyer information, cargo carrier information and the like. Therefore, the blockchain platform can determine the production and operation activity participants in the activity information according to the activity information.

in this embodiment, when multicasting the activity information in the activity request to each node in the node group, the blockchain platform first encrypts the data of the activity information to avoid the leakage of the activity information and protect the privacy of the activity information.
Alternatively, when data encryption is performed on the activity information, it can be realized by zero knowledge proof. A zero knowledge proof means that the prover proves one thing to the verifier, but does not reveal any critical information to the verifier event. For example, Hash operation or Cyclic Redundancy Check (CRC) may be performed on the activity information to obtain feature information of the activity information, and the feature information is used as the encrypted activity information, so that even if other users obtain the feature information, the corresponding activity information cannot be reversely derived according to the feature information.
Step S32, multicasting the encrypted activity information to each node in the node group, where the node in the node group performs zero-knowledge verification on the encrypted activity information and outputs a verification result, so that a user of the node in the node group triggers a confirmation instruction according to the verification result, and the node in the node group stores the encrypted activity information when receiving the confirmation instruction.
In this embodiment, the blockchain platform multicasts the encrypted activity information to each node in the node group, so that the nodes in the node group store the encrypted activity information. When receiving the encrypted activity information, the nodes in the node group verify the encrypted activity information, and output corresponding verification results through the terminal devices corresponding to the nodes, so that the users corresponding to the nodes trigger confirmation instructions or denial instructions according to the verification results, wherein the verification results can include that the activity information is real information or the activity information is false information. When receiving the confirmation instruction sent by the terminal device, the node in the node group indicates that the activity information is real and effective, and therefore, the node can store the encrypted activity information.
Optionally, when verifying the encrypted activity information, the node in the node group may be implemented by zero knowledge proof. For example, when the encrypted activity information is the feature information obtained through the hash operation, the node may obtain the activity information of the user corresponding to the node, and perform the hash operation on the activity information to obtain the standard feature information, if there is at least one standard feature information corresponding to the activity information in the plurality of activity information of the user corresponding to the node that is consistent with the feature information of the encrypted activity information, it indicates that the activity information is the real information, otherwise, the activity information is the false information, thereby implementing the verification of the authenticity of the encrypted activity information.
In the technical scheme disclosed in this embodiment, data encryption is performed on the activity information, the encrypted activity information is multicast to each node in the node group, the node in the node group verifies the encrypted activity information, the leakage of the activity information is avoided by encrypting the activity information, and the privacy of the activity information of each ecological link in the industry is further ensured.

When receiving a uplink request sent by an internet platform, the blockchain platform indicates that a user terminal wants to join a blockchain corresponding to the blockchain platform, and therefore, the blockchain platform can acquire identity information in the uplink request so as to perform identity verification on an enterprise of the user terminal through the identity information.
Step S02, verifying the identity information;
in this embodiment, when the blockchain platform verifies the identity information, the blockchain platform may send the identity information to a predetermined website for querying to detect whether the identity information is true or valid. Or sending the identity information to a preset node in the block chain for the user of the preset node to perform identity verification. For example, when the ue sends a uplink request, the identity information may include information such as a business name, a corporate identity, a business license, a business address, revenue records, and a social unified credit code. The preset website can be a website corresponding to the administration organization and the tax department, and the preset node can also be a block chain node corresponding to the administration organization and the tax department.
Step S03, when the identity information is successfully verified, associating the user terminal corresponding to the identity information with a preset block link point, so that the user terminal can initiate the activity request through the preset block link point.
In this embodiment, after the identity authentication is successful, it indicates that the user terminal can be added into the blockchain, and therefore, the blockchain platform can associate the user terminal corresponding to the identity information with the preset blockchain link point to allocate the preset blockchain node to the user terminal, the user terminal can initiate an activity request through the preset blockchain node, and each ecological link in the industry can transmit information through the blockchain, thereby achieving the purpose of industry interconnection.
Optionally, the blockchain platform corresponds to a plurality of blockchains, and different blockchains correspond to different industry types, where the industry types may include manufacturing industry, finance, medical treatment, education, and the like, and enterprises of each node in a single blockchain belong to an ecological link in the same industry. Therefore, when the user terminal corresponding to the identity information is associated with the preset block chain link point, the block chain platform can determine the industry type of an enterprise to which the user terminal belongs according to the identity information, obtain a target block chain corresponding to the industry type in a plurality of block chains corresponding to the block chain platform, and associate the user terminal with the preset block chain node in the target block chain, so that classification of the nodes corresponding to the enterprise is achieved, and operation and maintenance complexity of the block chain platform is reduced. Because different user terminals can be added into the block chain of the corresponding industry, the industry interconnection based on the block chain can be constructed, and the user terminals can carry out production and operation activities through the block chain, so that the purpose of interconnection of each ecological link in the industry is realized.
