The first data exchange party and the second data exchange party in this embodiment can log in the target node, download the data to be exchanged transmitted from the scheduling node, and confirm the data to be exchanged to be downloaded through the label of the data to be exchanged, thereby implementing that the first data exchange party downloads the second data to be exchanged from the target node, and the second data exchange party downloads the first data to be exchanged from the target node.
Specifically, the step of refining in the step S10 includes:
step a1, when receiving a data exchange instruction, creating a data exchange task containing a data acquisition contract in the scheduling node or the source node.
And a step a2, uploading the data exchange task to the main chain after the data exchange task is established.
And a step a3 of downloading the data exchange task from the main chain when the downloading instruction sent by the source node is detected.
The source node and the scheduling node can each create a data exchange task containing a data acquisition contract, when the source node or the scheduling node receives a request for establishing the data exchange task, one data exchange task is created in the scheduling node or the source node and stored in a data exchange task table, then the data acquisition contract is installed in the scheduling node or the source node, the data acquisition contract is stored in the contract table, after the data exchange task is created, the data exchange program can generate a task uplink request, then the data exchange task can be sent from the data exchange task table to the upper link queue table and wait for uploading to the main link, and the data exchange task needing uploading to the main link at the same time can be more than one data exchange task needing to be uploaded to the main link in the upper link queue table, so that the data exchange task needing uploading to the main link in the upper link queue table can need to be queued and the source node can download the data exchange task just uploaded from the main link.
Specifically, the steps following step S10 include:
and b1, when the target data exchange party is detected to log in the scheduling node, receiving a data exchange request sent by the target data exchange party.
Specifically, the step of refining in step S20 includes:
and b2, running a data acquisition contract in the data exchange task to acquire a storage path of the target data exchange party and a transmission path corresponding to the data exchange request.
And b3, screening the first data exchange party and the second data exchange party from the target data exchange parties according to the storage path and the sending path.
The target data exchange party in this embodiment is any party requesting data exchange, when detecting that the target data exchange party logs in the scheduling node in an account number and password manner, the target data exchange party receives a data exchange request sent by the target data exchange party, and knowing that before the target data exchange party sends out the data exchange request, the scheduling node or the source node needs to create a task exchange instruction containing a data acquisition contract in advance, and when running the data acquisition contract, the data exchange program can acquire a storage path of the target data exchange party logging in the scheduling node, because of the data exchange involved, at least two target data exchange parties needing to exchange data and log in the scheduling node exist, and knowing that the data exchange request sent by the target data exchange party carries a sending path, the sending path in this embodiment can be understood as a destination, that is, the present embodiment provides a specific application scenario where data to be exchanged needs to be sent, where the storage path of company a is X, the storage path of company B is Y, company a logs on the scheduling node and sends a data exchange request, the data exchange request carries data A1 that company a needs to exchange and the storage path X of company a, and company B logs on the scheduling node and sends a data exchange request, the data exchange request carries data B1 that company B needs to exchange and the storage path Y of company B, by acquiring the storage paths of company a and company B, and the sending path carried by the data exchange request, the data exchange program can screen out a first data exchange party and a second data exchange party that perform data exchange from the target data exchange party, specifically, if the storage paths and the sending paths of the two data exchange parties are opposite to each other, i.e. company a has a storage path equal to that of company B, and company a has a transmission path equal to that of company B, then company a and company B are the first data exchange party and the second data exchange party, respectively.
Specifically, the step of refining in the step b3 includes:
and c1, screening out the same target paths in the storage path and the transmission path, and taking the target paths as target data exchange parties corresponding to the storage path and the target paths as target data exchange parties corresponding to the transmission path as first data exchange parties and second data exchange parties respectively.
In this embodiment, a specific application scenario is given, where the storage path of company a is X, the storage path of company B is Y, company a logs in the scheduling node and sends a data exchange request, where the data exchange request carries data A1 that needs to be exchanged by company a and a storage path X of company a, and company B logs in the scheduling node and sends a data exchange request, where the data exchange request carries data B1 that needs to be exchanged by company B and a storage path Y of company B, in this embodiment, the target paths are X and Y, and taking the target path X as an example, when X is the storage path, the corresponding target data exchange party is company a, and when X is the sending path, the corresponding target data exchange party is company B, and then company a and company B are respectively the first data exchange party and the second data exchange party.

Step d3, the first exchange data is sent to the second data exchange party through the interface of the target node, and the second exchange data is sent to the first data exchange party through the interface of the target node.
It is known that a network channel between the scheduling node and the target node may be closed, for example, a network signal is poor due to network fluctuation occurring between the nodes, and in this case, the switching data received by the scheduling node cannot be normally transmitted, where the first switching data and the second switching data may be transmitted through the main chain, specifically, the data switching program uploads the first switching data and the second switching data to the main chain, then, when the data switching program detects that the first data switching party and the second data switching party log on the target node, the first switching data and the second switching data are downloaded to the target node, and finally, the first switching data are transmitted to the second data switching party through an interface of the target node, and the second switching data are transmitted to the first data switching party, so as to complete data switching.
In this embodiment, the data exchange system includes a scheduling node, a target node and a main chain, when a data exchange instruction is received, a data exchange task corresponding to the data exchange instruction is downloaded from the main chain, the data exchange task includes a data acquisition contract, the data acquisition contract is operated, a first data exchange party and a second data exchange party which are required to exchange data outside the data exchange system are confirmed, the scheduling node receives first exchange data uploaded by the first data exchange party, the second data exchange party uploads second exchange data, the uploaded first exchange data and second exchange data are transmitted to the target node, finally, the first data exchange party can download second exchange data from the target node through an interface of the target node, the second data exchange party can download the first exchange data from the target node, so that data exchange between the first data exchange party and the second data exchange party is completed, the data exchange between the first data exchange party and the second data exchange party does not pass through a block chain, the potential safety hazard of data transmission is eliminated, the authentication expense of the block chain and the storage space is reduced, and the data exchange efficiency is improved.

and step S50, if the network channel between the scheduling node and the target node is in an open state, transmitting the first exchange data and the second exchange data from the scheduling node to the target node.
Step S60, if the network channel is in a closed state, transmitting the first exchange data and the second exchange data from the scheduling node to the proxy node, and transmitting the first exchange data and the second exchange data to the target node through the proxy node.
The data exchange system in this embodiment is known to be suitable for a case that data transmission is not performed by using a main chain, specifically, the scheduling node or the source node creates a data exchange task, and data acquisition contracts in the data exchange task are operated, so that after the data acquisition contracts are acquired from the outside of the data exchange system, the data security transmission program determines whether the network channel between the scheduling node and the target node is in an open state or a closed state, if the network channel between the scheduling node and the target node is in an open state, the data exchange program transmits the first exchange data and the second exchange data from the scheduling node to the proxy node, and transmits the first exchange data and the second exchange data to the target node through the proxy node, wherein the open state refers to a state that the network channel between the scheduling node and the target node is in a closed state, and the open state refers to a state that the network channel between the scheduling node and the target node is in a communication state, and the proxy node is a communication state, and the communication state between the proxy node and the target node is not in a communication state, and the communication state can be performed between the node and the target node.

And step S42, when the second data exchange party is detected to log in the target node, the first exchange data is downloaded to the second data exchange party through an interface of the target node.
