The invention provides a data management method based on a block chain.
Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of a data management method based on a block chain according to the present invention.
In one embodiment, the block chain-based data management method includes:
in step S10, the requesting node broadcasts a data transaction request with the requested node via the blockchain network, where the data transaction request includes transaction attribute data.
In this embodiment, a requesting user broadcasts a data transaction request with a requested user through a first node, i.e. a requesting node, of the blockchain network, for example, if a user a needs data of a user B, the user a needs to send a data transaction request to the user B through the blockchain network, where the user a is the requesting user and the user B is the requested user. The data transaction request includes transaction attribute data that may include, but is not limited to, the name of the data requesting the transaction, the identity of the desired user, the first transaction identity, and the like.
Step S20, the demanded party node acquires the data transaction request through the blockchain network, and sends a transaction response request corresponding to the data transaction request to the blockchain network according to the transaction attribute data of the data transaction request, where the transaction response request includes response attribute data, and the response attribute data includes a data identifier.
The required user obtains the data transaction request through a second node of the blockchain network, namely a required party node (the second node may be the same as or different from the first node), and analyzes whether the data transaction request is sent to the required user or not according to transaction attribute data of the data transaction request. If the data transaction request is sent to the requested user, the requested user sends a transaction response request corresponding to the data transaction request to the blockchain network through the second node, and the transaction response request comprises response attribute data. The response attribute data can comprise an identity of the required user, an identity of the requiring user, a first transaction identity and the like; or the response attribute data comprises an identity of the demanded user, an identity of the demanding user, a first transaction identity, a data identity of data corresponding to the data transaction request in the data hosting server, and the like.

Step S50, if the transaction response request is verified to be valid, the accounting node of the blockchain network writes the response attribute data of the transaction response request into the intelligent contract of the blockchain network, so as to complete the broadcast of the response attribute data to each node of the blockchain network.
If the transaction response request is verified to be valid by the transaction verification node, the accounting node of the blockchain network determines that the data transaction of the requiring user and the required user is valid, and response attribute data of the transaction response request is written into an intelligent contract of the blockchain network so as to complete the broadcast of the response attribute data to each node of the blockchain network.
In the embodiment, after the transaction verification node verifies that the data transaction of the requesting user and the requested user is valid, the response attribute data is broadcasted to each node of the block link network to complete the data transaction, so that invalid transaction is prevented, and the security of the data transaction is further improved.

The data transaction request includes transaction attribute data that may include, but is not limited to, the name of the data requesting the transaction, the identity of the desired user, the first transaction identity, and the like.
The demanded party node acquires the data transaction request through the block chain network, and sends a transaction response request corresponding to the data transaction request to the block chain network according to the transaction attribute data of the data transaction request, wherein the transaction response request comprises response attribute data, and the response attribute data comprises data identification.
The required user obtains the data transaction request through a second node of the blockchain network, namely a required party node (the second node may be the same as or different from the first node), and analyzes whether the data transaction request is sent to the required user or not according to transaction attribute data of the data transaction request. If the data transaction request is sent to the requested user, the requested user sends a transaction response request corresponding to the data transaction request to the blockchain network through the second node, and the transaction response request comprises response attribute data. The response attribute data can comprise an identity of the required user, an identity of the requiring user, a first transaction identity and the like; or the response attribute data comprises an identity of the demanded user, an identity of the demanding user, a first transaction identity, a data identity of data corresponding to the data transaction request in the data hosting server, and the like.
And after the demand party node acquires the response attribute data in the transaction response request through the block chain network, determining a data identifier in the response attribute data, and downloading data corresponding to the data identifier from a preset data hosting server according to the determined data identifier. For example, the demander node sends a data downloading request including a demander identity identifier and the data identifier to a preset data hosting server; and receiving data corresponding to the data identification, which is sent by the data hosting server in response to the data downloading request.
In the embodiment, by means of data transaction based on the blockchain network and centralized management of data in the data hosting server, not only is time for finding data everywhere saved, but also the blockchain network is used for data transaction, and the characteristics of decentralization, information non-falsification and the like of the blockchain network can be utilized to greatly improve the security of data transaction and storage.

For example, if the identity of the required user contained in the response attribute data of the transaction response request is consistent with the identity of the required user in the corresponding transaction attribute data, the identity of the required user contained in the response attribute data is consistent with the identity of the required user in the corresponding transaction attribute data, the first transaction identity contained in the response attribute data is consistent with the first transaction identity in the corresponding transaction attribute data, and the response attribute data contains the data identity, it is determined that the transaction response request is valid; or if the response attribute data does not contain the data identifier, the identity identifier of the demanded user contained in the response attribute data is inconsistent with the identity identifier of the demanded user in the corresponding transaction attribute data, or the first transaction identifier contained in the response attribute data is inconsistent with the first transaction identifier in the corresponding transaction attribute data, determining that the transaction response request is invalid.
And if the transaction response request is verified to be valid, the accounting node of the blockchain network writes response attribute data of the transaction response request into an intelligent contract of the blockchain network so as to complete the broadcast of the response attribute data to each node of the blockchain network.
