S101, obtaining data to be uplink.
For example, the data to be uplink may be all data generated by the terminal block chain when performing any service, or may be data input by the user, for example, when the terminal block chain completes a review of a certain document, the data that may be generated includes document original content, identity information of a reviewer, relevant policy information, and the like. The mode of acquiring the data to be uplink may be directly receiving input data of a user, or may be data obtained by searching a database, and it should be noted that the data to be uplink is not limited to characters, but may also be graphical image information. The specific content and the obtaining manner of the uplink data to be processed are not limited in this embodiment, and those skilled in the art can determine the content and the obtaining manner as needed.
S102, classifying the data to be uplink according to a first preset rule, and dividing the data to be uplink into first block chain data and second block chain data, wherein the first block chain data represents the data to be stored in the edge server block chain, and the second block chain data represents the data to be stored in the terminal block chain.
For example, the first preset rule may be a rule in a preset rule base in which preset regulations and restrictions are stored. For example, the rule base specifies in advance: information which expresses user identity, such as user name information, public/private key pair information and the like, is used as first block chain data; when the task is executed, the generated other data information is second blockchain data, such as policy information, related material retrieval information, review result information, and the like related to the review content in the document review process. The terminal node performs one-to-one matching division on the data to be uplink transmitted according to a first preset rule, and divides the data to be uplink transmitted into first block chain data and second block chain data, wherein the first block chain data are data to be stored in an edge server block chain, and the second block chain data are data stored in a terminal block chain.
And S103, storing the first block chain data to the edge server block chain.

And S104, storing the second block chain data to the terminal block chain.
Exemplarily, when the block chain-based data storage method in this embodiment is applied to any terminal node in a terminal block chain, the second block chain data record is stored in a terminal block chain ledger for the terminal block chain to complete a corresponding service, such as a document review service. When the block chain-based data storage method in this embodiment is applied to an edge server node in a terminal block chain, the divided second block chain data is sent to the terminal block chain through a side chain technique, and the second block chain data is stored in a terminal block chain account book record.
It should be noted that in this embodiment, a terminal node of the terminal block chain may be in an online state or an offline state, and the terminal block chain may be connected to any terminal node, or any terminal node may exit the terminal block chain at any time. However, the edge server in any terminal block chain is a fixed node and a super node, and needs to be in an online state for a long time, so that the service data of the whole terminal node can be stored conveniently. In this embodiment, the edge server simultaneously completes data interaction between the edge server block chain and the terminal block chain for the nodes in the corresponding edge server block chain and the corresponding terminal block chain.
The data storage method based on the blockchain provided by this embodiment implements combination of high performance response of the edge server and a distributed self-organizing mode of the blockchain, where a terminal node in the self-organizing mode changes with a change in location, and an edge server in a butt joint with the terminal node also changes, for example, the edge server in the butt joint with the terminal node changes to be the closest edge server, thereby implementing data storage in a loosely-coupled environment.

The specific content of the first-level data and the second-level data is not limited in this embodiment, and those skilled in the art can determine the specific content as needed.
And secondly, storing the first grade data obtained by division into an edge server block chain in a data original text form.
Illustratively, when the first grade data exists after the data division is performed according to the second preset rule, the first grade data is stored in the form of a data original text in the edge server block chain in a distributed on-chain synchronous mode.
And thirdly, storing the divided second grade data into the edge server block chain in a data abstract mode, wherein the importance of the first grade data is greater than that of the second grade data.
Illustratively, when there is second level data after data partitioning according to a second preset rule, the second level data is subjected to a data summarization algorithm to obtain a data summary of the second level data, and the data summarization algorithm may be MD5, SHA1, SHA512, and the like.

As an optional implementation manner of this embodiment, step S104 includes:
first, the second blockchain data is classified according to a third preset rule.
Illustratively, the third preset rule may be that the second blockchain data is classified according to importance into third level data and fourth level data, the third level data represents important data, and the fourth level data represents normal data. Taking a document review as an example, the third level data may be review result information or the like, and the fourth level data may be policy information, related material search information or the like related to the review content. The specific content of the third-level data and the fourth-level data is not limited in this embodiment, and those skilled in the art can determine the third-level data and the fourth-level data as needed.

And performing data summarization on the fourth-level data obtained by division, and storing the fourth-level data in a terminal block chain in a data summarization mode, wherein the importance of the third-level data is greater than that of the fourth-level data.
Illustratively, when third-level data exists after data division is performed according to a third preset rule, the third-level data is stored in a distributed on-link synchronization mode in the terminal block chain in a format of a text. And when fourth-grade data exists after data division is carried out according to a second preset rule, obtaining a data abstract of the fourth-grade data through a data abstract algorithm for the fourth-grade data, wherein the data abstract algorithm can be MD5, SHA1, SHA512 and the like, and the terminal block chain carries out data uplink storage on the data abstract of the fourth-grade data.
