TABLE 1

Each node in the data sharing system stores one identical blockchain. Referring to fig. 2, which shows a schematic structural diagram of a block chain provided in an exemplary embodiment of the present application, as shown in fig. 2, each block 202 is included in the block chain 201, as can be seen from fig. 2, the block chain 201 may be composed of a plurality of blocks 201, a starting block includes a block header and a block body, the block header stores an input information characteristic value, a version number, a timestamp, and a difficulty value, and the block body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

When generating each block in the block chain, please refer to fig. 3, which shows a schematic diagram of a new block generation process provided in an exemplary embodiment of the present application, where a node where the block chain is located checks input information when receiving the input information, stores the input information in a memory pool after the check is completed, and updates a hash tree used for recording the input information; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(virsion+pre_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the data sharing system where the newly generated blocks are located according to the node identifications of the other nodes in the data sharing system, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.

The embodiment of the present application provides a data management method based on a block chain, which may be applied to the data sharing system shown in fig. 1, so as to implement intercommunication of data of each server, and improve reliability of data storage. Referring to fig. 4, a flowchart of a method for block chain based data management according to an exemplary embodiment of the present application is shown, where the method may be applied to the data sharing system shown in fig. 1, and is executed by each node (server) operating in the system. As shown in fig. 4, the block chain-based data management method may include several steps as follows.

Step 401, acquiring a resource transfer record of a first account in a block chain.

The resource transfer record may be a resource transfer record of each node in the blockchain to the first account stored in the blockchain.

Step 402, according to the resource transfer record of the first account in the block chain, generating a resource transfer check table, where the resource transfer check table includes the resource transfer record of the first account.

The server serving as a node in the block chain may perform uplink storage on the resource transfer record of the first account, and when the resource transfer checking table needs to be generated, the server in the block chain may obtain the stored resource transfer record from the block chain, so as to generate the resource transfer checking table according to the obtained resource transfer record. The resource transfer check table may be a fixed-format resource transfer check table pre-agreed between the server manufacturer and the owner of the first account. For example, the server serving as a node in the block chain is a bank server, the owner of the first account is an enterprise, the bank and the enterprise may previously specify a format of the resource transfer check table, and the bank server may obtain the resource transfer record stored in the block chain and generate a corresponding resource transfer check table.

Step 403, sending the resource transfer check table to a target user, where the target user is a user to which the first account belongs.

Optionally, the server serving as a node in the blockchain may send the generated resource transfer check table to a target user, where the target user may be an enterprise user or an individual user. Correspondingly, the server can send the generated resource transfer checking table to a terminal of an account checking person in the enterprise user, and the terminal of the account checking person can display an interface of the resource transfer checking table, so that the account checking person operates in the interface to complete checking of the resource transfer checking table.

Step 404, receiving the checking result of the target user to the resource transfer checking table, and storing the checking result into the block chain.

Optionally, after the target user checks the received resource transfer check table, the target user may return the generated check result to the corresponding server, and after receiving the check result, the server may perform uplink storage on the check result, so that transparency of storing the check result may be achieved.

In summary, the resource transfer record of the first account in the block chain is acquired through the server, the resource transfer checklist is generated according to the resource transfer record of the first account in the block chain, the resource transfer checklist is sent to the target user, the checking result of the target user on the resource transfer checklist is received, and the checking result is stored in the block chain. According to the method and the device, the resource transfer record of the first account is stored in the block chain through the use of the block chain, the resource transfer checking table is generated through the transfer record in the block chain, and the data checking result of the target user is stored in the block chain, so that the data of the target user can be shared by all nodes on the block chain, and the transparency and the reliability of the data of the target user are improved.

In a possible implementation manner, the blockchain may perform uplink storage on the resource transfer record generated by the server of the first account and related to the first account before the resource transfer checking table is generated, so as to describe the embodiment shown in fig. 4. Referring to fig. 5, a flowchart of a method for block chain based data management according to an exemplary embodiment of the present application is shown, where the method may be applied to the data sharing system shown in fig. 1, and is executed by each node (server) operating in the system. As shown in fig. 5, the block chain-based data management method may include several steps as follows.

Step 501, when a first resource transfer record is generated for a first account, the first resource transfer record is stored in a block chain through an intelligent contract.

The first resource transfer record is a resource transfer record generated when the first account performs resource transfer any time. Optionally, when the first account performs resource transfer, the server that generates and stores the first resource transfer record of the first account is used as one of the nodes of the block chain, and may store the first resource transfer record into the block chain through an intelligent contract, and store the first resource transfer record on the block chain. Optionally, the server may perform uplink transmission of the first resource transfer record in a desensitized uplink manner.

Optionally, when the first account is a bank account, and when a fund transfer occurs to the bank account, the fund transfer record generated by the bank server performs uplink storage. If the bank server is used as one of the nodes of the block chain, the bank server can link the generated fund transfer record through the intelligent contract. When the first resource transfer record is a fund transfer record of a bank account, the uplink data of the bank server may include fund information and transaction information of the bank account.

In a possible implementation manner, the blockchain related to the embodiment of the present application is a federation chain composed of different server nodes, and data synchronization is performed between each node based on a Peer-to-Peer (P2P, Peer to Peer) network characteristic of the blockchain. Optionally, the first resource transfer record generated by the current server may also be stored in each node in the block chain by performing bypass uplink through other nodes. For example, bank a may store its own first resource transfer record in the uplink via the server of bank B.

Step 502, storing a first record address on the block chain, where the first record address is an address where the first resource transfer record is stored in the block chain.

After the server links the first resource transfer record to the block chain, the block chain may generate a corresponding first record address corresponding to the current uplink content and information such as a timestamp, and the block chain may return the uplink address to the current uplink server, and the server may perform uplink storage on the first record address again through an intelligent contract, so that each node in the block chain may know the storage condition of the current first resource transfer record.

The server may also store the first record address locally, that is, the server may store the first record address returned by the blockchain locally, and when querying the first resource transfer record, the server may query the first resource transfer record according to the first record address.

Step 503, establishing a binding relationship between the first record address and the first resource transfer record, and storing the binding relationship on the block chain.

Optionally, after obtaining the first record address returned by the blockchain, the server may also establish a binding relationship between the first record address and the first resource transfer record locally, so as to facilitate subsequent call. Please refer to table 2, which shows a table of correspondence between the block chain addresses and the resource transfer records according to an embodiment of the present application.

Block chain address	Resource transfer recording
		Block chain address one	Resource transfer record one
Block chain address two	Resource transfer record two
		Block chain address three	Resource transfer record three
……	……

TABLE 2

As shown in table 2, the correspondence between each block chain address and each resource transfer record is included, the server may establish a correspondence between the block chain address and the resource transfer record in the form of table 2 and store the correspondence locally, and perform uplink storage on the established correspondence through an intelligent contract, so that each node of the block chain may also obtain the correspondence.

Step 504, when or after the preset time node arrives, the resource transfer record in the first time period is obtained from the block chain.

The first time period is any time period before the preset time node.

Optionally, the preset time node and the first time period may be pre-stored in the server, for example, a fixed period value. Every other period (preset time node), the server can obtain the resource transfer record in the first time period from the blockchain. For example, the preset time node is the bottom of each month, and the first time period is one month before the time node, that is, every other month, the server may obtain the resource transfer record stored in the month from the blockchain.

Optionally, the manner in which the server obtains the resource transfer record stored in the month from the block chain may be to download, according to the block chain address stored locally, each resource transfer record corresponding to each block chain address from the block chain. In a possible implementation manner, the server may also obtain the resource transfer record stored in this month from table 2 stored in the server, which is not limited in this embodiment of the application. For example, when the first account number is a bank account number and the server is a bank server, the bank server may obtain each fund transfer record of the bank account number in the month according to the blockchain address of the fund transfer record of each transaction stored in the month.

And 505, generating a resource transfer check table in the first time period according to the resource transfer record in the first time period.

The server may generate the resource transfer check table in the first time period according to the resource transfer record in the first time period acquired from the blockchain. For example, according to the above-mentioned first time period being one month, the server may generate the resource transfer check table for the month according to each resource transfer record in the month acquired from the blockchain. Still taking the first account as a bank account and the server as a bank server as an example, the bank server obtains a fund transfer record of the bank account within a certain month, and generates a resource transfer checking list (also called a statement) of the bank account within the certain month.

Please refer to fig. 6, which illustrates a schematic structural diagram of a resource transfer check table according to an exemplary embodiment of the present application. As shown in fig. 6, each fund transfer record 601, balance information 602, and fund transfer time 603 for the month in which the first account number is included. The server may generate the resource transfer check table of the first account in the month as shown in fig. 6 according to each resource transfer record in the month in which the first account is acquired from the blockchain.

Optionally, the server may further perform uplink storage on the generated resource transfer check table, where the uplink storage includes storing the resource transfer number, the resource remaining number, and the resource hash value of the resource transfer check table into the block chain. If the resource transfer checking table shown in fig. 6 is used, the data stored in the uplink by the server may have the fund transfer details, the balance, the hash value of the data, and the like included in fig. 6. That is, the server performs uplink storage on the generated resource transfer check table, so that the resource transfer check table may also exist in the block chain, thereby implementing the transparency of the resource transfer check table. Optionally, the resource hash value may be calculated by referring to the description in fig. 3 of the merchant, which is not described herein again.

Optionally, the block chain may also return the storage address of the resource transfer check table to the server, and the server may store the storage address of the resource transfer check table in the server similarly to the above address storage of the resource transfer record, and the execution details may refer to the above storage of the address of the resource transfer record by the server, which is not described herein again. It should be noted that fig. 6 is only an example, the resource transfer check table in practical application may also include other information, and accordingly, the server may also uplink store the other information.

Step 506, the resource transfer check list is sent to the target user, and the target user is the user to which the first account belongs.

Optionally, the target user may establish, in the server in advance, demand information for obtaining the resource transfer check table, and the server may determine, according to the demand information, the target user to which the first account belongs, and send the generated resource transfer check table to the target user. Optionally, when the target user is an enterprise user and the first account is a bank account of the enterprise user, the server sends the generated resource transfer checklist to a terminal of a worker performing checking in the enterprise user, and the terminal of the worker can display an interface of the resource transfer checklist, so that the reconciliation worker operates in the interface to complete checking of the resource transfer checklist.

Optionally, the server of the first account may further send a prompt message to the enterprise user, where the prompt message may indicate that the resource transfer check table has been sent to the enterprise user, so as to remind the enterprise user to perform the check. For example, the bank may send a short message, a communication message, or the like to the enterprise user, or the bank staff may notify the enterprise user by telephone, thereby informing the enterprise user that the resource transfer check list has been sent by the enterprise user. Optionally, the staff of the bank can also perform uplink storage on the prompt message through the bank server, so that the transparency of the flow data is achieved.

Optionally, the server may also send the storage address of the original transfer check table to the target user. That is, the server may send the storage address of the stored resource transfer check table on the blockchain to the target client, for example, the prompt message sent by the server to the target user includes the storage address of the resource transfer check table generated at the certain time on the blockchain, and the target user may query the resource transfer check table through the address, check the resource transfer check table, formulate a corresponding check result, and return the check result and the storage address to the server together.

And 507, receiving the checking result of the target user to the resource transfer checking table, and storing the checking result into the block chain.

After the target user receives the resource transfer checklist, the resource transfer checklist may be checked. Please refer to fig. 7, which illustrates an interface diagram of a terminal verification interface according to an exemplary embodiment of the present application. As shown in fig. 7, the terminal interface 700 includes a resource transfer check table 701, a check control 702, a submission control 703, and a remark input box 704. The target user may view the resource transfer checklist table 701, select the check control 702, input relevant information (for example, no error, which of the tables has an error, and the like) in the remark input box 704, and finally click the submission control 703, so that the check result is returned to the server that sends the resource transfer checklist table, and the check is completed. After receiving the check result, the server may also perform uplink storage on the check result, and optionally, the uplink manner may refer to the related contents, which is not described herein again.

Optionally, corresponding to an optional implementation manner in the step 506, the server may also receive the check result including the storage address, and perform uplink storage on the received check result.

In a possible implementation manner, taking the first account as a bank account and the target user as an enterprise user as an example, please refer to fig. 8, which shows a flowchart of a method for a data management method based on a blockchain according to an exemplary embodiment of the present application. As shown in fig. 8, the block chain-based data management method may include several steps as follows.

At step 801, a payment transaction occurs for a business.

In daily life, enterprises can carry out modes such as online banking payment and loan exchange, so that payment transactions occur in own bank accounts, and the enterprises can store corresponding transaction information in the enterprises, such as the amount of the payment transactions and the running information of the transactions sent at this time.

At step 802, the bank server generates a transaction record.

The bank server may generate a transaction record for the bank account corresponding to the amount of money actually transferred out or in by the bank account of the enterprise, where the transaction record may include transaction flow and fund flow information.

In step 803, the bank server stores the transaction record in uplink.

The bank server can bypass uplink of the transaction record by calling the intelligent contract. Optionally, the uplink data may include the serial number, the service number, the transaction amount, and the like of the transaction.

At step 804, the blockchain stores the transaction record.

At step 805, the blockchain returns the address of the transaction record to the bank server.

That is, the blockchain returns the on-chain address of the noted transaction record, from which the bank server can query the stored transaction record.

Step 806, the bank server establishes a binding relationship for the address and the corresponding transaction record.

Namely, the bank server can bind the address returned by the blockchain with the previous transaction record, so that the later-stage tracing is facilitated.

The bank server generates a statement on a periodic basis, step 807.

The bank server can summarize monthly, quarterly, semi-annually and annually statement bills according to the information such as the transaction records of the enterprises, and the specific period can be determined between the enterprises and the banks, which is not limited in the application.

Step 808, the bank server performs uplink storage on the bill.
