Description

[0002] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods, namely blocks. Each block contains a batch of network transaction information, which is used to verify the validity of its information and generate the next block. It can be understood that the blockchain includes a series of blocks that are connected to each other in the order of their generation. Once a new block is added to the blockchain, it will not be removed. The block records the record data submitted by the nodes in the blockchain network.

[0003] In traditional technology, the transaction pool capacity and related configuration parameters of the nodes in the blockchain network are fixed. When the number of transactions cached in the transaction pool of the node reaches the transaction pool capacity of the node, the node will no longer be able to receive transaction data, resulting in the loss of transaction data.

[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The data processing method based on blockchain provided in this application can be applied to Figure 1In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can be set up separately and can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other servers. Among them, the terminal 102 can be, but is not limited to, various desktop computers, laptops, smart phones, tablet computers, vehicle-mounted terminals, intelligent voice interaction devices, aircraft, smart home appliances and portable wearable devices. Smart home appliances can be smart speakers, smart TVs and smart air conditioners. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, cloud security, host security and other network security services, CDN, and basic cloud computing services such as big data and artificial intelligence platforms. The terminal 102 and the server 104 can be directly or indirectly connected by wired or wireless communication, and this application is not limited here.

[0048] The terminal 102 may send the transaction data to be stored in the blockchain network to the server 104. The server 104 may receive the transaction data to be stored in the blockchain network, obtain the configured distribution strategy, select the target node from the nodes of the blockchain network according to the configured distribution strategy, and send the transaction data to the target node. The transaction data is used to instruct the target node to store the transaction data in the blockchain network. The server 104 obtains the transaction cache volume and the transaction pool configuration capacity of the target node, and determines the transaction pool usage rate of the target node based on the transaction cache volume and the transaction pool configuration capacity. When the transaction pool usage rate exceeds the preset usage rate, the server 104 updates the configured distribution strategy, wherein the frequency of sending transaction data to the target node indicated by the updated distribution strategy is lower than the frequency of sending transaction data to the target node indicated by the configured distribution strategy.

[0049] In one embodiment, Figure 2 As shown, a data processing method based on blockchain is provided, which can be applied to a computer device, which can be a terminal or a server, that is, the method can be executed by the terminal or the server alone, or can be implemented through interaction between the terminal and the server. This embodiment takes the method applied to a computer device as an example for explanation, and includes the following steps:

[0050] Step 202, receiving transaction data to be stored in the blockchain network.

[0051] Among them, the blockchain network is a distributed database. The blockchain network includes multiple nodes, which jointly maintain and update the data status through the collaboration of multiple nodes. The main characteristics of the blockchain network include decentralization, high security, high reliability, high transparency and high efficiency. Decentralization means that the blockchain storage is decentralized, and the data is stored on each node in the entire network, rather than concentrated on a central server. This means that the data will not be lost due to the failure of a single node, and it is more difficult to be attacked and tampered with. High security means that the blockchain storage uses cryptography and distributed protocols, and the information security in the data encryption and verification process is very high, and cannot be modified or tampered with, which can ensure the security of the data. High reliability means that the blockchain storage uses data replication and data verification mechanisms to ensure the reliability and integrity of the data. Even if some nodes fail or the data is destroyed, the data can be restored through other nodes. Transparency means that all data in the blockchain storage is publicly visible, and anyone can view and verify the data in it, which can ensure the transparency and fairness of the data. Efficiency means that the blockchain storage uses a distributed data storage and processing method, which can quickly process and store large amounts of data with high efficiency. Transaction data refers to digital transaction records transmitted and stored in the network, and is an important part of the blockchain. Each transaction data contains a lot of information, such as the sender, receiver, transaction amount, transaction type and timestamp, etc. This information is packaged into transaction data and transmitted in the network.

[0052] Specifically, the client can obtain the transaction data to be stored in the blockchain network and send the transaction data to the computer device. The computer device can receive the transaction data to be stored in the blockchain network sent by the client.

[0053] Step 204, obtain the configured distribution strategy, select a target node from the nodes of the blockchain network according to the configured distribution strategy, and send the transaction data to the target node, where the transaction data is used to instruct the target node to store the transaction data in the blockchain network.

[0054] The distribution strategy is a scheme for distributing transaction data to nodes in the blockchain network. It is understood that the distribution strategy specifies the nodes to which the transaction data is distributed and the frequency of data transmission for the nodes to which the transaction data is distributed. The target node is the node to which the transaction data is distributed specified in the distribution strategy. It is understood that the number of target nodes is at least one.

[0055] Specifically, the computer device can obtain the configured distribution strategy, and select at least one target node specified by the configured distribution strategy from the nodes of the blockchain network. For each target node, the transaction data is sent to the target node according to the data sending frequency for the target node specified by the configured distribution strategy. After receiving the transaction data, the target node can verify the legitimacy of the transaction data, and generate a block based on the transaction data after the legitimacy verification is passed. It can be understood that the block includes the transaction data. Furthermore, the target node can broadcast the block to the blockchain network for consensus, and add the block to the blockchain network for storage after the consensus is passed.

[0056] In one embodiment, Figure 3 As shown, the process of generating a new block can be described as follows: the computer device can receive the transaction data sent by the client. For each target node, the computer device can send the transaction data to the target node according to the data sending frequency for the target node specified by the configured distribution strategy. The target node can receive the transaction data and cache the transaction data in the transaction pool. The computer device can verify the legitimacy of the transaction data in the transaction pool, and package the transaction data into blocks after the legitimacy verification is passed. It can be understood that the block includes transaction data. Furthermore, the target node can broadcast the block to other nodes in the blockchain network except the target node for consensus, and add the block to the blockchain network for storage after other consensuses are passed.

[0057] In one embodiment, Figure 4 As shown, it is a schematic diagram of the block structure in the blockchain network. Each block includes the transaction data stored in this block and the hash value of the transaction data, that is, the hash of this block, and the hash value of the transaction data in the previous block, that is, the hash of the previous block. Taking block 2 as an example, block 2 includes the transaction data stored in block 2 and the hash value of the transaction data, that is, the hash of this block, and the hash value of the transaction data in block 1, that is, the hash of the previous block. Taking block 3 as an example, block 3 includes the transaction data stored in block 3 and the hash value of the transaction data, that is, the hash of this block, and the hash value of the transaction data in block 2, that is, the hash of the previous block. Each block is connected by a hash value to form a blockchain. It can be understood that the block can also include information such as the timestamp when the block is generated.

[0058] In one embodiment, for each target node, the computer device may obtain the network address of the target node, and send the transaction data to the target node according to the network address of the target node.

[0059] In one embodiment, the computer device may obtain the operating status of each node in the blockchain network, and the operating status may include normal and abnormal. Furthermore, the computer device may select a target node with a normal operating status from the nodes of the blockchain network according to the configured distribution strategy. It is understood that a node with an abnormal operating status may have a fault or be offline.

[0060] Step 206, obtaining the transaction cache volume and transaction pool configuration capacity of the target node, and determining the transaction pool utilization rate of the target node according to the transaction cache volume and transaction pool configuration capacity.

[0061] The transaction cache volume is the amount of transaction data cached in the node's transaction pool. The transaction pool configuration capacity is the maximum amount of transaction data cached for the node's transaction pool configuration.

[0062] Specifically, for each target node, the computer device can obtain the transaction cache volume and transaction pool configuration capacity of the target node from the blockchain network, and determine the transaction pool utilization rate of the target node based on the ratio of the transaction cache volume to the transaction pool configuration capacity.

[0063] In one embodiment, for each target node, the computer device may directly use the ratio of the transaction cache volume to the transaction pool configuration capacity as the transaction pool usage rate of the target node.

[0064] In one embodiment, for each target node, the computer device may obtain a weighting coefficient, and determine the transaction pool usage rate of the target node based on the weighting coefficient and the ratio of the transaction cache volume to the transaction pool configuration capacity.

[0065] In one embodiment, for each target node, the computer device may obtain the transaction cache capacity of the target node from the software development kit provided by the blockchain network. Also, the computer device may obtain the node configuration file of the target node, and read the transaction pool configuration capacity of the target node from the node configuration file of the target node.

[0066] Step 208, when the transaction pool usage rate exceeds the preset usage rate, the configured distribution strategy is updated, wherein the updated distribution strategy indicates a frequency of sending transaction data to the target node, which is lower than the frequency of sending transaction data to the target node indicated by the configured distribution strategy.

[0067] Specifically, for each target node, the computer device can obtain a preset usage rate for the target node, and when the transaction pool usage rate of the target node exceeds the preset usage rate, the configured distribution strategy is updated. Among them, the frequency of sending transaction data to the target node indicated by the updated distribution strategy is lower than the frequency of sending transaction data to the target node indicated by the configured distribution strategy before the update. It can be understood that if the updated distribution strategy also specifies the distribution of transaction data to the target node, the frequency of data sending to the target node by the updated distribution strategy is lower than the frequency of data sending to the target node by the configured distribution strategy before the update. If the updated distribution strategy no longer specifies the distribution of transaction data to the target node, the updated distribution strategy indicates that transaction data is no longer distributed to the target node, that is, the frequency of data sending to the target node by the updated distribution strategy is zero.

[0068] In one embodiment, for each target node, when the transaction pool usage rate of the target node exceeds the preset usage rate, the computer device can obtain the transaction cache volume and transaction pool configuration capacity of each node in the blockchain network, and update the configured distribution strategy according to the transaction cache volume and transaction pool configuration capacity of each node in the blockchain network. It can be understood that each node in the blockchain network includes the target node and the remaining nodes in the blockchain network except the target node.

[0069] In one embodiment, the computer device may determine the transaction pool usage of each node according to the transaction cache volume and transaction pool configuration capacity of each node in the blockchain network, and update the configured distribution strategy based on the transaction pool usage of each node in the blockchain network.

[0070] In the above-mentioned blockchain-based data processing method, by receiving transaction data to be stored in the blockchain network, a configured distribution strategy is obtained, and according to the configured distribution strategy, a target node is selected from the nodes of the blockchain network, and the transaction data is sent to the target node, and the transaction data is used to instruct the target node to store the transaction data in the blockchain network. The transaction cache volume and transaction pool configuration capacity of the target node are obtained, and the transaction pool utilization rate of the target node is determined based on the transaction cache volume and the transaction pool configuration capacity. When the transaction pool utilization rate exceeds the preset utilization rate, the configured distribution strategy is updated, wherein the frequency of sending transaction data to the target node indicated by the updated distribution strategy is lower than the frequency of sending transaction data to the target node indicated by the configured distribution strategy. Compared with traditional data processing methods, the present application calculates the real-time transaction pool usage rate of the target node by obtaining the transaction cache amount and transaction pool configuration capacity of the target node from the blockchain network. When the real-time calculated transaction pool usage rate exceeds the preset usage rate, it means that the number of transaction data cached in the transaction pool of the target node has almost reached the transaction pool capacity of the target node. At this time, by timely updating the configured distribution strategy, the frequency of sending transaction data to the target node is reduced, and the frequency of sending transaction data to other nodes in the blockchain network except the target node is increased, thereby achieving node load balancing and avoiding the loss of transaction data.

[0071] In one embodiment, the method further includes: obtaining the block interval, block capacity and transaction validity period of the target node; determining the standard capacity of the transaction pool of the target node based on the block interval, block capacity and transaction validity period; obtaining the transaction pool configuration capacity of the target node; when the transaction pool configuration capacity does not match the transaction pool standard capacity, adjusting at least one of the transaction pool configuration capacity, block interval, block capacity or transaction validity period of the target node.

[0072] Among them, the block interval is the interval between nodes generating blocks. It can be understood that the block interval is the time it takes for a node to generate a block. Block capacity is the amount of transaction data that can be accommodated in a block. Transaction validity period is the validity period of transaction data. The transaction pool standard capacity is the optimal capacity of the node's transaction pool. It can be understood that if the transaction pool capacity is greater than the transaction pool standard capacity, the transaction data cached in the transaction pool is likely to become invalid due to exceeding the transaction validity period. If the transaction pool capacity is less than the transaction pool standard capacity, it will lead to a waste of node processing power.

[0073] Specifically, the computer device can obtain the block interval duration, block capacity and transaction validity duration of the target node from the blockchain network, and calculate the target node's transaction pool standard capacity based on the target node's block interval duration, block capacity and transaction validity duration. Furthermore, the computer device can obtain the target node's transaction pool configuration capacity, and compare the target node's transaction pool configuration capacity with the transaction pool standard capacity. When the transaction pool configuration capacity does not match the transaction pool standard capacity, the computer device can adjust at least one of the target node's transaction pool configuration capacity, block interval duration, block capacity or transaction validity duration.

[0074] In one embodiment, the transaction pool configuration capacity does not match the transaction pool standard capacity, which may be that the transaction pool configuration capacity is not equal to the transaction pool standard capacity.

[0075] In one embodiment, the computer device may determine the standard capacity range based on the standard capacity of the trading pool. The mismatch between the configured capacity of the trading pool and the standard capacity of the trading pool may be that the configured capacity of the trading pool does not fall within the standard capacity range.

[0076] In one embodiment, the computer device may obtain the transaction pool configuration capacity, block interval duration, block capacity, and transaction validity duration from the node configuration file of the target node.

[0077] In the above embodiment, the target node's transaction pool standard capacity is determined by obtaining the block interval, block capacity and transaction validity period of the target node, and based on the block interval, block capacity and transaction validity period. When the transaction pool configuration capacity does not match the transaction pool standard capacity, it means that the current configuration for the target node is not optimal and there is still room for optimization. At this time, by adjusting at least one of the transaction pool configuration capacity, block interval, block capacity or transaction validity period of the target node, compared with the traditional data processing method in which the transaction pool capacity and its related configuration parameters are fixed, this embodiment can optimize the configuration for the target node, thereby further avoiding the loss of transaction data.

[0078] In one embodiment, based on the block interval, block capacity and transaction validity period, the standard capacity of the transaction pool of the target node is determined, including: determining the transaction consumption speed of the target node according to the product of the block capacity and the block interval; determining the standard capacity of the transaction pool of the target node according to the product of the transaction validity period and the transaction consumption speed.

[0079] Among them, the transaction consumption speed is the speed at which the node processes transaction data.

[0080] In one embodiment, the computer device can determine the transaction consumption speed of the target node based on the product of the block capacity and the block interval, and directly use the product of the transaction validity period and the transaction consumption speed as the standard capacity of the transaction pool of the target node.

[0081] In one embodiment, the computer device may directly use the product of the block capacity and the block interval as the transaction consumption speed of the target node, and determine the standard capacity of the transaction pool of the target node based on the product of the transaction validity period and the transaction consumption speed.

[0082] In one embodiment, the computer device may directly use the product of the block capacity and the block interval as the transaction consumption speed of the target node, and directly use the product of the transaction validity period and the transaction consumption speed as the standard capacity of the transaction pool of the target node.

[0083] In one embodiment, the target node's transaction pool standard capacity can be calculated using the following formula:

[0084] consume_speed=block_capacity×block_interval

[0085] best_tx_capacity=tx_timeout×consume_speed

[0086] Among them, block_capacity represents the block capacity of the target node, block_interval represents the block interval of the target node, consume_speed represents the transaction consumption speed of the target node, tx_timeout represents the transaction validity period of the transaction data, and best_tx_capacity represents the standard capacity of the transaction pool of the target node.

[0087] In one embodiment, the computer device may obtain a first weighting coefficient, and determine the transaction consumption speed of the target node based on the first weighting coefficient and the product of the block capacity and the block interval time. Furthermore, the computer device may obtain a second weighting coefficient, and determine the standard capacity of the transaction pool of the target node based on the second weighting coefficient and the product of the transaction validity time and the transaction consumption speed.

[0088] In the above embodiment, the transaction consumption speed of the target node is determined by multiplying the block capacity by the block interval, and the standard capacity of the transaction pool of the target node is determined by multiplying the transaction validity period by the transaction consumption speed. This can improve the accuracy of the standard capacity of the transaction pool, so as to better optimize the configuration of the target node, thereby further avoiding the loss of transaction data.

[0089] In one embodiment, the standard capacity of the transaction pool of the target node is determined according to the product of the transaction validity period and the transaction consumption speed, including: determining the initial standard capacity of the transaction pool of the target node according to the product of the transaction validity period and the transaction consumption speed; obtaining the node memory capacity of the target node and the memory occupancy of each transaction data; determining the maximum capacity of the transaction pool according to the ratio of the node memory capacity to the memory occupancy; and determining the smaller one of the initial standard capacity of the transaction pool and the maximum capacity of the transaction pool as the standard capacity of the transaction pool of the target node.

[0090] Among them, memory usage is the amount of memory occupied by a transaction data. The maximum capacity of the transaction pool is the maximum amount of transaction data that the node's transaction pool can accommodate.

[0091] Specifically, the computer device can determine the initial transaction pool standard capacity of the target node based on the product of the transaction validity period and the transaction consumption speed. It can be understood that the initial transaction pool standard capacity is not the transaction pool standard capacity finally determined by the target node. The memory usage of each transaction data is the same. The computer device can obtain the node memory capacity of the target node and the memory usage of each transaction data, and determine the ratio of the node memory capacity to the memory usage. The computer device can determine the maximum capacity of the transaction pool based on the ratio of the node memory capacity to the memory usage. Furthermore, the computer device can compare the initial transaction pool standard capacity with the maximum capacity of the transaction pool, and determine the smaller of the initial transaction pool standard capacity and the maximum capacity of the transaction pool as the transaction pool standard capacity of the target node.

[0092] In one embodiment, the computer device may directly use the product of the effective duration of the transaction and the transaction consumption speed as the initial transaction pool standard capacity of the target node. The computer device may obtain the node memory capacity of the target node and the memory usage of each transaction data, and determine the ratio of the node memory capacity to the memory usage. The computer device may directly use the ratio of the node memory capacity to the memory usage as the maximum capacity of the transaction pool. Furthermore, the computer device may compare the initial transaction pool standard capacity with the maximum capacity of the transaction pool, and determine the smaller of the initial transaction pool standard capacity and the maximum capacity of the transaction pool as the target node's transaction pool standard capacity.

[0093] In one embodiment, the maximum capacity of the transaction pool of the target node can be calculated by the following formula:

[0094] max_tx_capacity = node memory capacity / memory usage of a transaction data

[0161] Step 1130, when the transaction pool configuration capacity is less than the transaction pool standard capacity, at least one of increasing the transaction pool configuration capacity, shortening the block interval, reducing the block capacity, or shortening the transaction validity period is adjusted for the target node.

[0162] The present application also provides an application scenario, which applies the above-mentioned blockchain-based data processing method. Specifically, the blockchain-based data processing method can be applied to the transaction data processing scenario in the payment field. It can be understood that the transaction data includes payment transaction data, and the payment transaction data includes payment information such as the payer, the recipient, the payment amount, the payment type and the timestamp in the payment field. Specifically, the computer device can receive the payment transaction data to be stored in the blockchain network; obtain the configured distribution strategy, select the target node from the nodes of the blockchain network according to the configured distribution strategy, and send the payment transaction data to the target node, and the payment transaction data is used to indicate that the target node stores the payment transaction data in the blockchain network; obtain the transaction cache amount and the transaction pool configuration capacity of the target node, and determine the transaction pool utilization rate of the target node according to the transaction cache amount and the transaction pool configuration capacity; when the transaction pool utilization rate exceeds the preset utilization rate, the remaining capacity of the transaction pool of the target node is determined according to the difference between the transaction pool configuration capacity of the target node and the transaction cache amount of the target node; according to the ratio of the remaining capacity of the transaction pool of the target node to the transaction pool configuration capacity of the target node, the transaction pool availability of the target node is determined.

[0163] The computer device can obtain the transaction cache volume and transaction pool configuration capacity of the remaining nodes, and the remaining nodes are nodes other than the target node in the blockchain network; the remaining capacity of the transaction pool of the remaining nodes is determined according to the difference between the transaction pool configuration capacity of the remaining nodes and the transaction cache volume of the remaining nodes; the transaction pool availability of the remaining nodes is determined according to the ratio of the remaining capacity of the transaction pool of the remaining nodes to the transaction pool configuration capacity of the remaining nodes. According to the transaction pool availability of the target node and the transaction pool availability of the remaining nodes, the updated node is determined from the target node and the remaining nodes; the frequency of sending payment transaction data to the updated node is determined to obtain the updated distribution strategy obtained by updating the configured distribution strategy, and the determined frequency is positively correlated with the transaction pool availability of the updated node. Among them, the frequency of sending payment transaction data to the target node indicated by the updated distribution strategy is lower than the frequency of sending payment transaction data to the target node indicated by the configured distribution strategy.

[0164] The computer device can obtain the block interval, block capacity and transaction validity period of the target node; determine the transaction consumption speed of the target node according to the product of the block capacity and the block interval; determine the initial transaction pool standard capacity of the target node according to the product of the transaction validity period and the transaction consumption speed; obtain the node memory capacity of the target node and the memory usage of each payment transaction data; determine the maximum capacity of the transaction pool according to the ratio of the node memory capacity to the memory usage; determine the smaller of the initial transaction pool standard capacity and the transaction pool maximum capacity as the transaction pool standard capacity of the target node. Obtain the transaction pool configuration capacity of the target node; when the transaction pool configuration capacity is greater than the transaction pool standard capacity, adjust the target node to reduce the transaction pool configuration capacity, extend the block interval, increase the block capacity or extend the transaction validity period. When the transaction pool configuration capacity is less than the transaction pool standard capacity, adjust the target node to increase the transaction pool configuration capacity, shorten the block interval, reduce the block capacity or shorten the transaction validity period.

[0165] It can be understood that the present application calculates the real-time transaction pool usage rate of the target node by obtaining the transaction cache amount and transaction pool configuration capacity of the target node from the blockchain network. When the transaction pool usage rate calculated in real time exceeds the preset usage rate, it means that the number of payment transaction data cached by the transaction pool of the target node has almost reached the transaction pool capacity of the target node. At this time, by timely updating the configured distribution strategy, the frequency of sending payment transaction data to the target node is reduced, and the frequency of sending payment transaction data to other nodes in the blockchain network except the target node is increased, thereby achieving node load balancing and avoiding the loss of payment transaction data.

[0166] The present application also provides an application scenario, which applies the above-mentioned blockchain-based data processing method. Specifically, the blockchain-based data processing method can be applied to transaction data processing scenarios in the financial field. It can be understood that transaction data includes financial transaction data, and financial transaction data includes financial transaction information such as the initiator, the receiver, the transaction amount, the transaction type and the timestamp in the financial field. The present application calculates the real-time transaction pool usage rate of the target node by obtaining the transaction cache amount and the transaction pool configuration capacity of the target node from the blockchain network. When the transaction pool usage rate calculated in real time exceeds the preset usage rate, it means that the amount of financial transaction data cached by the transaction pool of the target node has almost reached the transaction pool capacity of the target node. At this time, by timely updating the configured distribution strategy, the frequency of sending financial transaction data to the target node is reduced, and the frequency of sending financial transaction data to other nodes in the blockchain network except the target node is increased, so as to achieve node load balancing, thereby avoiding the loss of financial transaction data.

Unless there is a clear explanation in this article, the execution of these steps does not have strict order restrictions, and these steps can be performed in other orders.
