Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the invention are shown in the drawings.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
FIG. 1 is a schematic diagram of a scenario of the batch processing of blockchain transactions of the present invention.
The trade mentioned in the present invention is divided into general trade and special trade, wherein the general trade refers to trade normally sent by a user, the timeliness of the trade has no special requirement on the sequency, and the special trade refers to trade of the current type which has a requirement on the sequence of the trade packaging before the next requirement after the last trade.
As shown in fig. 1, each of the clients a, B, and C sends a blockchain transaction, and stores the blockchain transaction in a transaction pool, wherein some transactions sent by the client a are special transactions, the special transactions and the general transactions are distinguished by a first identifier "" # ", the" # "is a general transaction, the" # "is a special transaction, a is a second identifier generated by the intelligent client a for distinguishing each client, the first number is denoted by" 1,2, and 3", and the client generates a cis-number for identifying the special transactions sent by the clients.
FIG. 2 is a flow chart of a method for batch processing of blockchain transactions according to an embodiment of the present invention.
As shown in fig. 2, in this embodiment, the present invention provides a batch processing method for a blockchain transaction, including:
s11, after a first transaction is obtained from the transaction pool, judging whether the first transaction is a special transaction according to the first identification:
if so, verifying whether the first transaction conforms to a predetermined format:
judging whether the first transaction is in order according to a preset sequence according to the first number of the first transaction:
if yes, packing the first transaction into a block;
if not, the first transaction is aborted and packed into blocks.
The first identification and the first number are generated by the client.
Specifically, in conjunction with the scenario shown in fig. 1, the transaction pools have transactions sent by clients a, B, C, … …, respectively, including general transactions and special transactions. The blockchain node acquires a first transaction tx1 from the transaction pool, and judges whether the transaction is a special transaction or not: when the transaction is judged to contain the first identifier ". Su", the transaction is judged to be a special transaction, and then whether the predefined format of the transaction is correct is further judged: judging whether the second identifier A is consistent with the second identifier corresponding to the client, if so, proving that the format is correct, wherein the transaction tx1 is really sent by the client A; finally, it is verified whether the first number "1" of the tx1 transaction is a homeopathic transaction to the special transaction issued by the client: if so, tx1 is packed into the block. Similarly, the identification and judgment of the next transaction are performed, as shown in fig. 1, the first identifier of the next transaction tx2 is "#", which is a general transaction, and only needs to judge whether the transaction tx2 accords with the predefined format: i.e., whether it is issued by client B, if so, the transaction is packed into blocks. Similarly, the identification and judgment of the next transaction tx3 are performed, it is determined that tx3 is a special transaction, and the transaction is actually issued by the client a, but the first number is "3", and the special transaction number issued by the last a in the currently packaged block is "1", tx3 is obviously not the next order number, so tx3 is thrown back into the transaction pool, and the judgment of the next transaction tx4 is performed, where the judgment mode is consistent with the above.
It should be noted that, the order of the special transaction referred to in the present invention refers to the order of the serial numbers, and the space is not necessarily adjacent, in other words, even if two orders of the special transaction are separated by a plurality of general transactions. The first identifier, the second identifier and the first number are examples of the embodiment, and other content expressions can be used, such as "Batch" for special transactions and "normal" for general transactions; the second identifier of the client may be represented by another unique identifier such as a block hash, and the first number may be represented by "a, b, c", etc., and in any case, the content is not limited by the embodiment, and the effect represented by the second identifier may be achieved.
In more embodiments, when a special transaction with a cis-serial number is not thrown back to the transaction pool, the transaction can be re-executed after a fixed number of blocks are executed in the current transaction pool, the transaction in the transaction pool can be executed after all the transactions are executed, and in combination with fig. 1, when tx3 is thrown back to the transaction pool, three blocks of next transactions tx4, tx5 and tx6 are executed, tx3 can be re-acquired, and tx3 can be executed after all the transactions are executed, wherein the difference is that the time for packing into blocks and linking up is different, and the time can be adjusted according to the requirements of users without being limited by the technology of the invention.
In further embodiments, prior to acquiring the first transaction, further comprising:
s10, receiving a registration transaction sent by a client, and returning a second identifier to the client after the registration transaction is successfully executed, wherein the verification of whether the first transaction accords with a preset format comprises the following steps:
verifying whether the second identity matches the client: if yes, the verification is passed.
Further, the second identification may be generated by the smart contract from the registered transaction hash, or may be generated by the registered transaction hash and the chunk height hash. The signature information may be generated in accordance with a predetermined format, or the signature information of the first transaction may be directly determined to be correct.
Fig. 3 is a flow chart of a preferred embodiment of the method of the present invention. In a preferred embodiment, as shown in fig. 3, the method further comprises:
s12, sending receipt information to the client side so that the client side judges whether the receipt information is received within a set time or not:
if the client does not receive the receipt information within the set time, the first transaction is resent to the blockchain node.
Specifically, the client sets the time of receipt, when the client sends the inquiry request information to inquire whether the first transaction is successfully packaged into a block and successfully uplinked, if the block chain node cannot find the cis-position transaction of the last special transaction all the time when the transaction is acquired, the client can determine that the transaction is likely to have problems in the middle of the transaction, such as loss, tampering and the like, according to the deadline of the time, at the moment, the client can resend the transaction, so that the client is prevented from waiting without any intention, and the working efficiency is improved.
Further, the first interface is configured to query the number of the current blockchain record for the client to adjust according to the number when the client still fails after the first transaction is resent a plurality of times.
Specifically, if the user sends the transaction for multiple times, the transaction number still cannot be continuously circulated, it may be stated that the number provided by the client itself is wrong, at this time, the client may query the number of the special transaction recorded in the current blockchain through the query interface configured by the blockchain, and reconfigure a new number for the next transaction, thereby providing a way for actively finding the problem of the client for the client, and further improving the working efficiency of the sending transaction.
