And S1201, if the verification result is that the data is not processed, feeding back prompt information which cannot be processed to the user terminal which sends the data transaction.
If the verification result is that the transaction data is not processed, the fact that transaction data corresponding to the data transaction is being processed at the moment is indicated, the data transaction conflicts with other data transaction transactions, at the moment, the cloud server cannot process the data transaction, and therefore prompt information which cannot be processed can be fed back to a user terminal sending the data transaction.
And S130, executing the data transaction to process transaction data matched with the data identification to obtain a data processing result and feeding back the data processing result to the user terminal.
And executing the data transaction to process transaction data matched with the data identifier to obtain a data processing result and feeding back the data processing result to the user terminal.

In addition, the process of processing the transaction data may also be performed in a terminal device of the blockchain network, for example, if the verification result of the data transaction by the cloud server is the process, the cloud server may feed back the verification result to the terminal device that sends the data transaction, where the user terminal includes a peer node corresponding to the data transaction, and the peer node stores the transaction data corresponding to the data transaction. After the terminal device obtains the verification result, the transaction data can be processed according to the data transaction to obtain a data processing result, at this time, the user terminal can feed back the data processing result to the cloud server, and the cloud server updates the identification information contained in the identification database according to the data processing result, that is, step S140 is executed.

S141, acquiring identification information matched with the data identification of the data processing result in the identification database as target identification information.
The identification information identical to the data identification can be obtained from the identification database according to the data identification contained in the data processing result, and then the identification information identical to the data identification is only one piece and is taken as the target identification information.
S142, deleting the target identification information from the identification database so as to update the identification information contained in the identification database.
And deleting the target identification information from the identification database, so that the processing procedure of updating the identification information contained in the identification database can be realized.
And S150, if the proposal information input by the user terminal is received, judging whether a preset synchronous database contains a proposal synchronous identification matched with the data identification of the proposal information.
If the proposal information input by the user terminal is received, judging whether a preset synchronous database contains a proposal synchronous identification matched with the data identification of the proposal information. The peer node of the user terminal stores the original transaction data matched with the data transaction, and after the user terminal receives the data processing result, the user terminal can synchronously update the original transaction data stored in the user terminal based on the data processing result. In this case, only the original transaction data stored by the user terminal in the blockchain network is updated, in order to update the original transaction data stored in other peer nodes in the blockchain network, the user terminal may send proposal information to the cloud server, where the proposal information is information for synchronously updating corresponding transaction data included in the entire blockchain network, and at least includes a calculation result obtained by calculating the original transaction data and a corresponding data identifier. Because a large amount of transaction data needs to be synchronized in the cloud server, a synchronization database is configured in the cloud server, wherein the synchronization database is a database for storing proposal synchronization identifiers, and the cloud server can perform synchronization processing on corresponding transaction data based on the proposal synchronization identifiers stored in the synchronization database, wherein the synchronization database can be a Redis database.
Judging whether the proposal synchronization identification matched with the data identification of the proposal information is contained in the synchronization database, judging whether the data identification of the proposal information is identical with the data identification contained in each proposal synchronization identification or not, if the data identification of the proposal information is identical with the data identification contained in the proposal synchronization identification, judging that the proposal information is matched with the proposal synchronization identification, otherwise, judging that the proposal information is not matched with the proposal synchronization identification.

If the proposal synchronization information matched with the data identification information is not contained in the synchronization database, the identification information contained in the proposal information can be locked first, if the data identification is locked, the transaction data corresponding to the data identification is indicated to be in the process of being updated, then a newly added proposal synchronization identification is generated according to the proposal information, and the newly added proposal synchronization identification is added into the synchronization database. Specifically, the newly added proposal synchronization identifier may be stored in the synchronization database in a key value opposite way, and the proposal synchronization identifier T may be composed of K and V, where K is a data identifier in the proposal information, V is a calculation result corresponding to the data identifier, V is to-be-synchronized transaction data in the proposal synchronization identifier, T is a code value obtained by combining K and V and then performing coding, and the code value T may be used as identification information uniquely corresponding to the proposal synchronization identifier. The generated proposal synchronization identification can be added into a synchronization database for storage, and at the moment, there is one and only one proposal synchronization identification matched with the data identification of the proposal information in the synchronization database.
For example, the code value T may be a code value obtained by adding hexadecimal K and hexadecimal V, and then base64 encoding or ASCII encoding the obtained added value; the code value T may be a code value obtained by sequentially splicing hexadecimal K and hexadecimal V, and then base64 encoding or ASCII encoding the spliced value.

If the number of proposal synchronization identifiers matched with the data identifiers in the synchronization database is S, after the newly added proposal synchronization identifiers are added into the synchronization database, the number of proposal synchronization identifiers matched with the data identifiers of the proposal information in the synchronization database is S+1.

Specifically, a plurality of proposal synchronization identifiers corresponding to the data identifiers in the synchronization database are sequentially arranged in sequence, and the proposal synchronization identifiers in the synchronization database follow the principle of first-in first-out, then one proposal synchronization identifier at the tail of the arrangement is the latest proposal synchronization identifier, and the one proposal synchronization identifier at the tail of the arrangement can be used as the target synchronization identifier corresponding to the data identifier.
For example, if a plurality of proposal synchronization identifiers corresponding to a certain data identifier in the synchronization database are in order: t (T) 1 、T 2 And T 3 ，T 1 From K 1 And V 1 Composition, T 2 From K 2 And V 2 Composition, where K 2 Comprises K 1 And T 1 ，T 3 From K 3 And V 3 Composition, where K 3 Comprises K 1 And T 2 The three proposal synchronization identifications all comprise the same data identification K 1 At this time, the proposal synchronization mark T at the end of the arrangement 3 Namely, the data identifier K is 1 And corresponding target synchronous identification.
S162, combining the target synchronous identification with the data identification and then combining the target synchronous identification with the transaction data to be synchronized of the proposal information to generate a newly added proposal synchronous identification.
In the process of generating the newly added proposal synchronous mark, the target synchronous mark is needed to be firstly identifiedCompounding with the data identification. For example, the target sync is identified as T 3 Data identification K 1 Compounding the target synchronous mark and the data mark to obtain K 4 ，K 4 Comprises K 1 And T 3 Will K 4 To-be-synchronized transaction data V in the proposal information 4 Is combined and according to K 4 And V 4 Obtaining corresponding code value T 4 As the identification information of the proposal synchronization identification, the newly added proposal synchronization identification which is finally generated can be expressed as T 4 ，T 4 The information contained in the data is composed of K 4 And V 4 Composition, where K 4 Comprises K 1 And T 3 。
S163, adding the newly added proposal synchronization identifier to the position after the target synchronization identifier in the synchronization database for arrangement.
And arranging the positions of the newly added proposal synchronous identifiers after the target synchronous identifiers, namely adding the newly added proposal synchronous identifiers into a synchronous database.
For example, a plurality of proposal synchronization identifiers obtained after adding the newly added proposal synchronization identifiers are sequentially arranged as follows: t (T) 1 、T 2 、T 3 、T 4 。

And according to the arrangement sequence of a plurality of proposal synchronous identifiers corresponding to the same data identifier in the synchronous database, synchronizing the transaction data to be synchronized with each proposal synchronous identifier into an account book of the blockchain network in sequence. Specifically, the synchronous database includes an arrangement sequence of a plurality of proposal synchronous identifiers corresponding to each data identifier, the transaction data to be synchronized of the first proposal synchronous identifier in the arrangement sequence is obtained and synchronized to an account book of the blockchain network, the account book is a storage channel for storing the transaction data in the blockchain network, the processing process is to synchronously update the original transaction data stored in a linked list position corresponding to the corresponding data identifier in the blockchain network according to the transaction data to be synchronized, after the transaction data to be synchronized of the first proposal synchronous identifier in the arrangement sequence is updated, if the next proposal synchronous identifier still exists in the arrangement sequence of the data identifier, the transaction data to be synchronized of the next proposal synchronous identifier is continuously updated synchronously.
