Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

Those skilled in the art can understand that the structure of the device shown in FIG. 1 does not constitute a limitation on the device, and may include more or fewer components than those shown in the figure, or a combination of certain components, or different component arrangements.

Based on the above hardware structure, an embodiment of the blockchain transaction method of this application is proposed.

Referring to Fig. 2, Fig. 2 is a schematic flowchart of a first embodiment of a blockchain transaction method according to this application. The method includes:

Step S10: Perform consensus packaging on the transaction information submitted by the client to obtain the block packaged transaction volume, and determine whether the block packaged transaction volume is less than a preset quick start threshold;

Consensus packaging can be transaction packaging through a consensus algorithm in the blockchain. Blockchain is a distributed storage system that is maintained and trusted by multiple nodes. The bottom layer of the blockchain is a chain composed of a series of blocks. In addition to recording the data of this block, each block also records the hash value of the previous block. In this way, a chained data structure is formed. Each node in the blockchain peer-to-peer network confirms a batch of transactions through an algorithm and ensures that all nodes have a consistent confirmation result for this batch of data. This algorithm is the consensus algorithm of the blockchain. Block packaging is in the blockchain, and any operation (deploy contract, call contract interface, etc.) is carried out by sending transactions. The transaction is initiated by the user and sent to the blockchain node through the client. After receiving the transaction, the blockchain node will package the transaction into a block and execute it. Consensus nodes are nodes that can participate in consensus block generation. The main functions include: packaging transactions in the transaction pool; executing transactions; running consensus algorithms and writing consensus blocks into the ledger. The block packaging transaction volume can be the transaction volume that can be packaged by the block. The initial value can be configured by yourself. Generally, the default value is 100. The algorithm dynamically adjusts it later. The consensus algorithm uses this value to determine the current block package transaction volume. The fast-start threshold can be the threshold of the fast-start phase. The default value is generally half of the maximum transaction volume of the block. It will be dynamically adjusted according to the block execution in the follow-up. When the current block package transaction number is less than this value, the algorithm works at In the quick start phase, when it is greater than or equal to, it works in the overtime avoidance phase.

When the submitted transaction sent by the client is received in the blockchain node, and the consensus module block executes the transaction normally, it will call back the normally executed callback interface, and the dynamic adjustment module will dynamically adjust according to the current state. That is, in the consensus process, the transaction packaging process needs to obtain the maximum transaction volume that can be packaged in the block from the dynamic adjustment module, and then load the transaction from the transaction pool. After the block is executed, the execution time, time consumption, and transaction volume of the block need to be changed. Information such as normal block execution or block execution timeout is called back to the dynamic adjustment module, and the dynamic adjustment module adjusts the transaction volume that the block can pack in the next round of consensus based on the callback information. Therefore, after obtaining the block packaging transaction volume, it is necessary to determine whether the block packaging transaction volume is less than the preset quick start threshold, and perform different operations according to the determination result.

Step S20: If it is determined that the block packaging transaction volume is less than the preset quick start threshold, the block packaging transaction volume is incremented to obtain the current block packaging transaction volume, and the current block packaging transaction volume is detected Whether the transaction volume is greater than the maximum transaction package volume of the block;

When it is judged that the block package transaction volume is less than the preset quick start threshold, it enters the quick start phase, which is the initial working phase of the dynamic adjustment algorithm. At this stage, the dynamic adjustment module does not have enough information to predict the transaction processing of the blockchain Therefore, the transaction processing capacity of the blockchain can be determined by adjusting the block packaging transaction volume, and since the initial value of the block packaging transaction volume is very small, the block packaging transaction volume can be increased in an exponential manner. Increment processing, and when the block package transaction volume after increment processing is greater than or equal to the quick start threshold, exit the quick start phase and enter the timeout avoidance phase.

In the timeout avoidance phase, the transaction volume of the block package exceeds the rapidly increasing threshold, and the possibility of block execution timeout occurring is relatively fast in the start phase. The possibility of block execution timeout has greatly increased, so the growth rate needs to be reduced. The size of the block packaging transaction volume is increased according to the configured rate (such as the transaction volume increase rate), and may also time out after the timeout avoidance phase increases to a certain extent, that is, when a timeout phenomenon is found, the priority is given to the processing of the timeout (ie Timeout processing stage), after adjusting the parameters, continue to the next timeout avoidance stage.

In the timeout processing stage, the consensus module block transaction timeout occurs, indicating that the transaction volume has increased too much, which has exceeded the transaction processing load capacity of the current blockchain. At this time, the block package transaction volume and the quick start threshold are set to the maximum Timeout transaction volume, and the quick start threshold is not greater than the minimum timeout transaction volume, and then enter the timeout avoidance phase again. Until the current block packaged transaction volume is obtained, and check whether the current block packaged transaction volume is equal to the block maximum transaction package volume. Perform different operations based on different detection results.

Among them, the transaction volume increase rate can be the rate at which the packaged transaction volume increases during the timeout avoidance phase. The initial value is configurable, and the default value is 0.1. The maximum untimed transaction volume may be the maximum transaction volume value of the block package that has been executed currently without a timeout. The minimum timeout transaction volume can be the minimum transaction volume value of the block that has been executed that has timed out. The maximum transaction volume of a block is the maximum transaction volume that can be packaged in a block, and the dynamic adjustment algorithm adjusts the limit value of the block package transaction volume.

In step S30, if it is determined that the current block packaging transaction volume is equal to the block maximum transaction packaging volume, block chain transactions are performed based on the current block packaging transaction volume.

When it is judged that the current block packaging transaction volume is equal to the block's maximum transaction packaging volume, it can be considered that the current block packaging transaction volume has reached the maximum value that the block can execute transactions. At this point, you can directly perform blockchain transactions according to the current block packaging transaction volume. When the current block packaging transaction volume is found to be less than the block maximum transaction packaging volume after judgment, the current block packaging transaction volume will continue to be increased until the current block packaging transaction volume is equal to the block maximum transaction packaging volume. However, when the current block packaged transaction volume is greater than the block's maximum transaction package volume, the current block node may be faulty.

In addition, in order to assist in understanding the blockchain transaction method in this embodiment, an example is given below.

For example, as shown in Figure 4, when the client submits a transaction to the transaction pool of the blockchain node, the transaction pool will load the transaction into the consensus module and execute the block through the block executor, that is, through the consensus module Consensus packaging, after reaching a consensus, the block will be chained, that is, the transaction information will be transferred to the block chain. And after uploading the transaction information to the blockchain, the block's execution time, time-consuming, transaction volume and other information will be called back to the dynamic adjustment module through the network module, so that the dynamic adjustment module can adjust the next block according to the block execution feedback information. Round consensus block package transaction volume, that is, the dynamic adjustment module needs to obtain the next round of block package transaction volume. Among them, when the consensus packaging transaction is carried out, consensus message interaction will be carried out through the network module to ensure that the transaction information can be successfully uploaded to the blockchain.

In this embodiment, the transaction information submitted by the client is packaged by consensus to obtain the block package transaction volume, and it is determined whether the block package transaction volume is less than the preset quick start threshold; The block packaged transaction volume is incremented to obtain the current block packaged transaction volume, and check whether the current block packaged transaction volume is equal to the block maximum transaction packaged volume; if it is equal to, the packaged transaction volume is based on the current block The amount of blockchain transactions. By obtaining the block packaged transaction volume corresponding to the transaction information, and when the block packaged transaction volume is less than the quick start threshold, the block packaged transaction volume is incremented to obtain the current block packaged transaction volume and package it in the current block When the transaction volume is equal to the maximum transaction packaging volume of the block, blockchain transactions are performed according to the current block packaging transaction volume, thereby ensuring that the block transaction efficiency is improved without affecting the normal transactions of the block nodes in the blockchain. This avoids the phenomenon that the existing technology uses configuration methods to perform block transactions to limit the block transaction volume.

Further, based on the first embodiment of the blockchain transaction method of the present application, a second embodiment of the blockchain transaction method of the present application is proposed. This embodiment is step S20 of the first embodiment of the present application. The step of increasing the block packaging transaction volume to obtain the current block packaging transaction volume is refined, including:

Step a: Obtain a preset processing method, and perform incremental processing on the block packaging transaction volume according to the preset processing method to obtain an incremental block packaging transaction volume;

The preset processing method may be a method for increasing the block packaging transaction volume stored in advance by the user, for example, increasing according to a certain ratio. Therefore, in this embodiment, when the block packaging transaction volume needs to be adjusted, the block packaging transaction volume can be increased through a preset processing method (such as exponential increase) to obtain the incremental block packaging transaction volume. The incremental block packaging transaction volume may be the current block packaging transaction volume after the increase is performed using a preset processing method.

Step b: Obtain the current block packaging transaction volume based on the incremental block packaging transaction volume.

When the incremental block packaging transaction volume is obtained, the incremental block packaging transaction volume can be compared with the quick start threshold, and the current block packaging transaction can be determined according to the comparison result.

In this embodiment, the block packaging transaction volume is incrementally processed according to a preset processing method, and the current block packaging transaction volume is obtained according to the incremental block packaging transaction volume after the incremental processing, thereby ensuring the current obtained The accuracy of the block package transaction volume.

Specifically, the step of obtaining the current block packaging transaction volume based on the incremental block packaging transaction volume includes:

Step b1, judging whether the incremental block packaging transaction volume is greater than or equal to the quick start threshold;

When the incremental block packaging transaction volume is obtained, it is also necessary to determine whether the incremental block packaging transaction volume is greater than or equal to the fast start threshold; if it is greater than or equal to, the fast start phase of the block packaging transaction volume can be considered to be completed and it is necessary to enter The timeout avoidance phase is to avoid incrementing the block package transaction volume to exceed the processing load capacity of the blockchain. However, if the incremental block packaging transaction volume is less than the quick start threshold, you can continue to increase the incremental block packaging transaction volume according to the preset processing method until the new incremental block packaging transaction volume is greater than or equal to the quick start Threshold.

Step b2: If it is determined that the incremental block packaging transaction volume is greater than or equal to the quick start threshold, the incremental block packaging transaction volume is increased based on a preset transaction volume increase rate to obtain the current block packaging transaction volume .

If it is found after judgment that the incremental block packaging transaction volume is greater than or equal to the quick start threshold, the preset transaction volume increase rate needs to be obtained, and the incremental block packaging transaction volume is increased according to the transaction volume increase rate until the obtained The incremental block packaging transaction volume is equal to the maximum transaction packaging volume of the block, and the incremental block packaging transaction volume is increased according to the preset transaction volume increase rate, and the incremental block packaging that has been increased at the current moment is obtained The transaction volume can be used as the current block package transaction volume. It should be noted that, in order to avoid the occurrence of ultrasonic phenomenon when the block packaging transaction volume is used for transactions, the increase rate of the block packaging transaction volume in the fast start phase is greater than that in the timeout avoiding phase, and the incremental block is packaged according to the transaction volume increase rate. The rate at which the transaction volume increases processing, that is, the rate at which the block packaged transaction volume is increased through a preset processing method is much greater than the rate at which the incremental block packaged transaction volume is increased according to the preset transaction volume increase rate. For example, as shown in Figure 5, the growth rate of the block packaged transaction volume during the fast start phase is significantly less than that of the block packaged transaction volume greater than or equal to the fast start threshold during the timeout avoidance phase. .

In this embodiment, when it is determined that the incremental block packaging transaction volume is greater than or equal to the quick start threshold, the increase processing is performed according to the preset transaction volume increase rate to obtain the current block packaging transaction volume, thereby ensuring the obtained The accuracy of the current block package transaction volume.

Specifically, the step of processing the incremental block packaging transaction volume based on a preset transaction volume increase rate to obtain the current block packaging transaction volume includes:

Step f: Performing an increase process on the incremental block packaging transaction volume based on a preset transaction volume increase rate to obtain multiple sub-block packaging transaction volumes, and performing timeout detection on each sub-block packaging transaction volume in turn;

After increasing the transaction volume of the incremental block package by the transaction volume increase rate, it is necessary to obtain the package transaction volume of each sub-block at different times (the sub-block package transaction volume is the package transaction volume of the incremental block through the transaction volume increase rate After the increase processing, the block package transaction volume at a certain moment), and after obtaining the package transaction volume of each sub-block, it is necessary to perform timeout detection on each sub-block package transaction volume in turn to determine whether there is a timeout phenomenon. , And perform different operations based on the results of each timeout detection.

Step g, if it is determined that there is a sub-block packaged transaction volume that fails overtime detection in each sub-block packaged transaction volume, then determine the maximum untimed transaction volume in each of the sub-block packaged transaction volume, and based on The maximum untimed transaction volume obtains the current block packaging transaction volume.

When it is found that there is a sub-block packaged transaction volume after the timeout detection is unqualified, it can be considered that the consensus module block execution transaction has timed out, and the transaction volume has increased too much, which has exceeded the transaction processing load capacity of the current blockchain. At this time, you need to determine the maximum untimed transaction volume in each sub-block packaged transaction volume, and you can set the quick start threshold and the sub-block packaged transaction volume that failed overtime detection to the maximum untimed transaction volume, and start quickly The threshold cannot be greater than the minimum timeout transaction volume, and after the setting is completed, the timeout avoidance phase is performed again, that is, the new increase rate is used to increase the sub-block package transaction volume that has been set to the maximum untimed transaction volume, and the current area is obtained Block package transaction volume. Among them, the maximum untimed transaction volume may be the maximum transaction volume value of the block package that has been executed currently without a timeout. The minimum timeout transaction volume can be the minimum transaction volume value of the block that has been executed that has timed out.

In this embodiment, the packaged transaction volume of each sub-block generated after the increase process is tested for timeout, and when it is determined that the timeout detection fails, the maximum untimed transaction volume is obtained, and the maximum untimed transaction volume is obtained according to the maximum untimed transaction volume. The current block packaging transaction volume ensures the accuracy of the obtained current block packaging transaction volume.

Specifically, the step of sequentially performing timeout detection on the packaged transaction volume of each of the sub-blocks includes:

Step h: Obtain the time period between the sending time of each sub-block packaged transaction volume from the block node to the blockchain and the feedback time of receiving the feedback information of the blockchain, and Determine whether there is a target time period that does not match the preset time period in the time period;

The timeout detection of the packaged transaction volume of each sub-block is performed in turn. Since the packaged transaction volume of the sub-block is uploaded to the blockchain, a feedback message will be returned to the node of the block where the packaged transaction volume of the sub-block is located, so each sub-area can be obtained in turn The time period between the time when the block package transaction volume is sent from the block node to the blockchain and the feedback time when the feedback information of the blockchain is received, and the existence and preset time period can be determined in each time period (user The set block chain normal transaction upload block chain time) does not match the target time period, and then perform different operations based on the determination result.

In step k, if it is determined that there is a target time period that does not match the preset time period, it is determined that the overtime detection of the sub-block packaging transaction volume corresponding to the target time period is unqualified.

When it is judged that there is a time period that does not match the preset time period in each time period, this time period can be used as the target time period, and then the sub-block package transaction volume corresponding to the target time period can be determined. It is determined that the timeout detection of the sub-block packaged transaction volume corresponding to the target time period is unqualified, and the timeout processing stage needs to be entered. However, if there is no target time period that does not match the preset time period in each time period, the increase processing can be continued.

In this embodiment, by sequentially detecting whether the time period corresponding to the packaged transaction volume of each sub-block does not match the preset time period, and when it is determined that the target time period does not match the preset time period, it is determined that the time period corresponding to the target time period The timeout detection of sub-block packaged transaction volume is unqualified, thus ensuring the effectiveness of the timeout detection.

Specifically, the step of obtaining the current block packaging transaction volume based on the maximum untimed transaction volume includes:

Step x: Adjust the transaction volume increase rate, and increase the maximum untimed transaction volume based on the adjusted transaction increase rate to obtain the current block packaged transaction volume.

When the processing is completed in the timeout processing phase and the timeout avoidance phase is entered again, the transaction volume increase rate needs to be adjusted, and the maximum untimed transaction volume is increased according to the adjusted transaction increase rate to obtain the increased transaction The current block package transaction volume.

In this embodiment, the transaction volume increase rate is adjusted, and the maximum untimed transaction volume is increased according to the adjusted transaction volume increase rate to obtain the current block packaged transaction volume, thereby ensuring the current obtained The accuracy of the block package transaction volume.

Further, after the step of detecting whether the current block packaging transaction volume is greater than the block maximum transaction packaging volume, the method includes:

Step y, if it is determined that the current block packaged transaction volume is less than the block maximum transaction package volume, continue to increase the current block packaged transaction volume according to the adjusted transaction increase rate until the current block The block packaging transaction volume is greater than or equal to the block maximum transaction packaging volume.

When it is judged that the current block packaging transaction volume is less than the block maximum transaction packaging volume, the current block packaging transaction volume can be increased according to the adjusted transaction increase rate until the current block packaging transaction volume is greater than or equal to the area Only when the maximum transaction volume of the block is reached, the increase processing operation is stopped.

In this embodiment, when it is determined that the current block packaged transaction volume is less than the block maximum transaction package volume, the current block packaged transaction volume is increased according to the adjusted transaction increase rate, thereby increasing the block transaction volume effectiveness.
