Embodiment 1

[0070] figure 1 It is a flowchart of a data transaction method shown according to an exemplary embodiment 1, refer to figure 1 , the method is applied to the data provider and may include the following steps:

[0071] Step S11, publish the basic information of the data to be traded in the blockchain system, so that the data demander can select data from the list of basic information according to their own needs, and submit the data purchase order to the blockchain system for approval. After passing, the data call request information is generated, and the data call request information is uploaded to the chain. After the chain, the block chain node in the blockchain system receives the data call request information and sends the data call request information. To the RabbitMQ message queue maintained by the blockchain node;

[0072] Step S12, receiving the data call request information pushed by the RabbitMQ message queue;

[0073] Step S13, analyzing the data call request inf...

Embodiment 2

[0107] image 3 It is a flow chart of a data transaction method shown according to an exemplary embodiment 2, refer to image 3 , the method is applied to the data demand side and may include the following steps:

[0108] Step S31, select data from the list of basic information according to one's own needs, and the basic information is the basic information that the data provider publishes the data to be traded in the blockchain system;

[0109] Step S32, after the selection is made, submit the data purchase order to the blockchain system for approval, and when the approval is passed, generate data call request information;

[0110] Step S33, uploading the data call request information, so that the block chain nodes in the block chain system receive the data call request information, and send the data call request information to the RabbitMQ maintained by the block chain nodes In the message queue, the RabbitMQ message queue pushes the data call request information to the da...

Embodiment 3

[0120] Figure 5 is a flow chart of a data transaction method according to an exemplary embodiment 3, refer to Figure 5 , the method is applied to a blockchain system, and may include the following steps:

[0121] Step S51, receiving the basic information of the data to be traded released by the data provider, so that the data demander can select data from the list of basic information according to its own needs;

[0122] Step S52, receiving the data purchase order submitted by the data demander;

[0123] Step S53, approve the data purchase order, and when the approval is passed, trigger the data demander to generate data call request information;

[0124] Step S54, receiving the data call request information generated by the data demander, and sending the data call request information to the RabbitMQ message queue;

[0125] Step S55, send the data call request information to the data provider through the RabbitMQ message queue, so that the data provider analyzes the data ...

Abstract

The invention discloses a data transaction method and device and electronic equipment. Comprising the steps of publishing basic information of to-be-transacted data in a block chain system; enabling a data demander to select data from the list of the basic information according to own demands, and submitting a data purchase order to a block chain system for examination and approval; after the approval is passed, generating data calling request information, and uploading the data calling request information; receiving the data calling request information by a block chain node in the block chain system after the data calling request information is linked, and sending the data calling request information to a RabbitMQ message queue maintained by the block chain node; receiving data calling request information pushed by the RabbitMQ message queue; analyzing the data calling request information and establishing a point-to-point data transmission channel with a data demander; and sending the to-be-transacted data to a data demand side through the point-to-point data transmission channel.

Description

technical field [0001] The present application relates to the technical field of data exchange, in particular to a data transaction method and device, and electronic equipment. Background technique [0002] With the continuous improvement of the global digital development level, data has become an important factor of production, and the transaction and circulation of data is imperative. In recent years, data trading models based on centralized data trading platforms have emerged, and explorations and attempts have been made in data transfer, but it is difficult to meet market requirements. The reason is that the electronic nature and easy duplication of data make it different from traditional production factors. Centralized data transactions have the problems of difficult to define data ownership, difficult to track, and low transaction efficiency. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a data transaction...
