Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a data processing method and device based on blockchain. Background Art

[0002] Under existing technical solutions, communication between multiple systems is mainly through Remote Procedure Call (RPC) or application program interface services. With the popularity of microservice architecture and fine-grained business segmentation, a request often needs to involve multiple services, and the services are interdependent. At the same time, service performance monitoring and troubleshooting have become very complex. An error in any node or intermediate link may cause the entire request to fail.

[0003] Taking the order relationship synchronization business scenario as an example, Figure 1 It is a flowchart of ordering relationship in the prior art, such as Figure 1 As shown, the existing process is initiated by the Business & Operation Support System (BOSS). BOSS uses the application program interface to synchronize user subscription relationship data to the main system in batches to activate benefits. The mesh network system forwards this information to the main system. After receiving the synchronized user data, the main system performs corresponding processing and informs the BOSS of the processing results.

[0004] by Figure 1 Taking the ordering relationship synchronization business in as an example, the BOSS generates the ordering relationship, synchronizes it to the mesh network system, and then forwards it to the main system through the mesh network routing. Since the ordering relationship is scattered among multiple BOSSes, the transaction data is scattered, the business process is long and has many links, and the checkpoints are prone to errors.

[0027] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0028] Blockchain is a decentralized, distributed architecture where all nodes in the network fully record all data on the chain, ensuring data security and reliability. If one party loses data, the complete data can be quickly restored, reducing the long process chain of data calls and improving the efficiency of data sharing and circulation. In this invention, a blockchain network is constructed, and the data uploader and data downloader self-build nodes to join the blockchain network. On this basis, in order to be able to process transaction data on the blockchain network in real time, by monitoring each block of the blockchain network in real time and using smart contract event-driven notifications, it can achieve automatic distribution and processing of transaction data, solving the problem of high-concurrency and real-time processing of transaction data on the blockchain.

[0029] Figure 2 The flowchart of an embodiment of a data processing method based on blockchain of the present invention is shown. The method is applied to the data downloader. In this embodiment, the data uploader can be the transaction initiator in the blockchain network; the data downloader can be the transaction receiver in the blockchain network; Figure 2 As shown, the method includes the following steps:

[0030] Step S210: Obtain the current blockchain information according to a preset time period, and parse the current blockchain information to determine the latest block.

[0031] Specifically, the data downloader can obtain the current blockchain information according to a preset time period and parse the current blockchain information to determine the latest block; wherein, the preset time period can be set according to the actual application scenario, for example, the data downloader can obtain the current blockchain information from the blockchain every 0.5 seconds.

[0032] In this embodiment, the data uploader can construct transaction data and save it to the InterPlanetary File System, obtain the hash value of the transaction data, write the hash value to the local blockchain node through the smart contract, and the local blockchain node synchronizes the hash value to other blockchain nodes.

[0033] Figure 3 A schematic diagram of a blockchain provided by an embodiment of the present invention is shown in FIG. Figure 3As shown, the data uploader and the data downloader each establish a local blockchain node and join the blockchain network, wherein the data uploader and the data downloader can upload or download transaction data through the Software Development Kit (SDK) or the Application Programming Interface (API); specifically, when the data uploader writes the transaction data to the blockchain, the data will be automatically synchronized on each node of the entire blockchain network, so that each blockchain node will participate in recording the transaction data; when the data uploader constructs the transaction data and saves it to the file management system, it obtains the hash value of the transaction data and calls the smart contract on the blockchain to synchronize the hash value to other blockchain nodes. Based on the data consensus of the blockchain, the transaction data of the nodes in the entire network are automatically synchronized, and the blockchain node of the data downloader will also record the hash value of the transaction.

[0034] This embodiment uses the blockchain network as an example of a blockchain operating system (Enterprise Operation System, EOS) designed for distributed applications to process transaction data on the chain; and uses the InterPlanetary File System (IPFS) as an example of a file management system to store the original data corresponding to the transaction data. Figure 4 The following is a schematic diagram of the interaction process between blockchain and IPFS provided by an embodiment of the present invention. Figure 4 As shown in the figure, the process of obtaining IPFS data operation credentials is as follows: the data uploader obtains the blockchain common account and account private key; constructs a token request structure for obtaining IPFS data upload; the IPFS gateway verifies the user information (account and account private key, etc.) entered by the data uploader; if the verification is successful, the token data is generated and returned to the data uploader.

[0035] The data transmission process in IPFS is as follows: the data uploader prepares the data to be transmitted, where the data to be transmitted can be the transaction data to be transmitted by the data uploader; organizes the Hypertext Transfer Protocol (HTTP) message based on the data to be transmitted, and uploads the data to be transmitted with a token; the IPFS gateway verifies the token message, and after the verification passes, forwards the data operation request to the IPFS file system; the IPFS file system saves the data and returns the corresponding hash value of the data to be transmitted.

[0036] The data downloader obtains the hash value corresponding to the data from the blockchain; organizes and obtains the data HTTP information based on the hash value; and carries the token to obtain the data to be transmitted; the IPFS gateway verifies the token information, and after the verification is passed, the IPFS file system returns the data to be transmitted to the data downloader.

[0037] The data transmission process on the blockchain is as follows: the data uploader prepares the hash value corresponding to the data, calls the smart contract (DAPP) based on the hash value to upload the data to the chain; the blockchain system conducts data consensus.

[0038] The data downloader obtains the hash value corresponding to the data through DAPP, and obtains the original data corresponding to the data from the IPFS file system based on the hash value; if the data to be transmitted prepared by the data uploader is transaction data to be transmitted, the original data corresponding to the transaction data transmitted by the data uploader is obtained from the IPFS file system based on the hash value.

[0039] In an optional manner, step S210 further includes: parsing the current blockchain information to obtain the latest block number; setting the current block number, and cyclically determining whether the current block number is less than the latest block number; if so, pulling the latest block from the blockchain, where the block number of the latest block is the current block number plus one.

[0040] Specifically, use EOS's chain / get_info interface to obtain the current blockchain information and parse the latest block number head_block_num from it; initialize the monitoring of the current block information, set the current block number start_block_num, DAPP account and the name of the smart contract action; among them, the current block refers to the block from which block data is obtained in sequence and which DAPP accounts and smart contract action names in the monitoring block are selected.

[0041] Taking the preset time period of 0.5 seconds as an example, in this step, the current blockchain information is obtained every 0.5 seconds, the current blockchain information is parsed to determine the latest block, and a loop is started to monitor and process the transaction data on the blockchain in real time. Specifically, the current block number current_block_num is initialized to start_block_number-1, and a loop is used to determine whether the current block number current_block_num is less than the latest block number head_block_num; if so, the latest block is pulled from the blockchain, and the block with the current block number plus one (i.e., current_block_num+1) is pulled once through the chain / get_block interface of EOS and recorded as the latest block new_block.

[0042] It should be noted that if the current block number is greater than or equal to the latest block number, after continuing to wait for a preset time period, step S210 is repeated to determine the latest block.

[0043] Step S220: Determine whether the latest block has been processed; if so, return to step S210; if not, execute step S230.

[0044] In an optional manner, step S220 further includes: obtaining the block number of the last processed block, and determining whether the block number of the last processed block is equal to the block number of the latest block; if so, determining that the latest block has been processed; if not, determining that the latest block has not been processed.

[0045] In an optional manner, after parsing the current blockchain information to determine the latest block and before determining whether the latest block has been processed, that is, after step S210 and before step S220, the method further includes: performing a hash check on the latest block to determine whether the latest block is an irreversible block; wherein, if the check passes, the latest block is determined to be an irreversible block.

[0046] It should be noted that if the latest block is a reversible block, the transaction data on the corresponding blockchain may be in an intermediate state, resulting in a fork in the transaction data. In this case, the transaction data pointed to by the latest block is not accurate. Therefore, after obtaining the latest block, it is necessary to first perform a hash check on the latest block to confirm that the latest block is the latest irreversible block of the blockchain main chain. In an optional method, performing a hash check on the latest block further includes steps 1-3:

[0047] Step 1: Get the hash value of the previous block saved in the latest block and the hash value of the current block corresponding to the current block number; determine whether the hash value of the previous block is equal to the hash value of the current block; if so, execute step 2; if not, jump to step 3.

[0048] Specifically, the characteristic of blockchain is an ordered chain. Each block saves the hash value of the previous block. According to the latest block new_block obtained in step S210, the hash value privious_block_hash pointing to the previous block is taken out from this latest block. Then, according to the current block current_block obtained by the last current block number current_block_num, the hash value block_hash of the current block itself is taken out. It is determined whether privious_block_hash is equal to block_hash; if so, execute step 2; if not, jump to step 3.

[0049] Step 2: Confirm that the hash of the latest block passes verification, update the current block to the latest block, and store the hash value of the current block in the historical block record.

[0050] If privious_block_hash is equal to block_hash, it means that the latest block new_block is the main chain data. The hash verification of the latest block is confirmed to be passed, and the current block current_block is updated to the latest block new_block. The hash value of the updated current block current_block is stored in the historical block record block_history.

[0051] Step 3: Roll back the data. Search for a historical block whose hash value is equal to the hash value of the previous block based on the historical block records. Replace the historical block with the current block, delete the on-chain data after the current block, and update the current blockchain information.

[0052] If privious_block_hash is not equal to block_hash, it means that the chain has forked, and the data is rolled back. According to the historical block record block_history, a historical block with a hash value equal to the hash value of the previous block is searched, and the historical block is replaced with the current block current_block. The on-chain data after the current block current_block is deleted, the current blockchain information is updated, and the block number corresponding to the unforked data is relocated to head_block_num.

[0053] In an optional manner, after the hash check is passed on the latest block new_block, it is determined whether the latest block new_block has been processed; specifically, the block number last_processed_block_Num of the last processed block is obtained, and it is determined whether the last processed block number last_processed_block_Num is equal to the block number current_block_num of the current block; if they are equal, it is determined that the latest block new_block has been processed, and the process returns to step S210 to wait for the next block polling; if they are not equal, it is determined that the latest block new_block has not been processed, and the process repositions to the block number of the last processed block plus last_processed_block_Num+1, and the process returns to step S210 to wait for the next block polling.

[0054] Step S230: Parse the data of the latest block and process the data of the latest block to obtain transaction data.

[0055] In this step, if it is determined that the latest block new_block has not been processed, the data of the latest block new_block is parsed and multi-threaded processing is performed on the data of the latest block new_block to obtain transaction data.

[0056] In an optional manner, step S230 further includes: parsing the latest block to obtain the action array of the latest block, searching for action data matching the smart contract by traversing the action array; and concurrently processing the action data by multi-threading to obtain transaction data.

[0057] Specifically, the latest block is parsed to obtain its action array (actions array), which is then looped through to find each action data matching the smart contract. Multithreading (disruptor) concurrently processes the action data to obtain transaction data. Action data can include data such as the hash value and timestamp corresponding to the transaction data. Each transaction data item is matched to a single thread. This approach enables real-time processing of massive amounts of transaction data under high-concurrency conditions on the chain.

[0058] Step S240: extract the hash value of the transaction data, obtain the original data corresponding to the transaction data based on the hash value, and distribute it to the business system for processing.

[0059] Taking the IPFS system as an example, the hash value of transaction data in the blockchain network can point to the original data corresponding to the transaction data corresponding to the hash value of the transaction data in the IPFS. Therefore, in this step, according to each transaction data, the hash value of the transaction data is extracted, and the IPFS interface is called according to the hash value to obtain the original data corresponding to the transaction data, and the original data corresponding to the transaction data is distributed to the back-end business system to process the original data according to its respective business logic; specifically, the original data corresponding to the transaction data includes data such as messages generated by the transaction data; after all transaction data is processed, the block data has been processed, and the block number last_processed_block_Num of the last processed block is updated to the current block number, and the process returns to step S210 to wait for the scheduling of the next block.

[0060] In an optional embodiment, the method further includes: saving the block number of the processed block to a database; when a failure occurs, retrieving the block number of the last processed block from the database; and monitoring and obtaining current blockchain information based on the block number of the last processed block.

[0061] Specifically, the processed block number can be saved to the database. In order to support more hash types, the Remote Dictionary Server (Redis) database is preferred to ensure that if there is an abnormal situation, the latest block data of the current blockchain information can be processed from this block number.

[0062] by Figure 1 The sub-BOSS system generates approximately 6 million transactions per day, and the sub-BOSS system concurrently writes the transaction data into the blockchain. The main system monitors the block chain in real time, and processes the transaction data on the blockchain in real time to enable subscription services for users. The blockchain ensures strong consistency in the subscription relationship between the sub-BOSS system and the main system, and enables real-time and high-concurrency processing of transaction data on the blockchain.

[0063] The method of this embodiment obtains current blockchain information according to a preset time period, parses the current blockchain information to determine the latest block; after the latest block passes the hash check, it is determined whether the latest block has been processed; if not, the data of the latest block is parsed and multi-threaded processing is performed on the data of the latest block to obtain transaction data; the hash value of the transaction data is extracted, the original data corresponding to the transaction data is obtained based on the hash value, and the original data is distributed to the business system for processing. This method builds a blockchain network and adds transaction data to the blockchain network, so that each blockchain node will participate in recording the transaction data, avoiding the problem of key checkpoint errors caused by the long business process due to the dispersion of transaction data; the method monitors each block in real time based on EOS and IPFS, obtains blockchain information from the blockchain network according to a preset period, monitors the transaction data corresponding to the latest block in real time, and then processes the transaction data in multiple threads. The original data is obtained from the InterPlanetary File System based on the hash value of the transaction data, realizing real-time multi-threaded processing of transaction data under high concurrency, ensuring normal and rapid transaction processing.

[0067] In an optional manner, the device further includes a verification module 520 for performing a hash verification on the latest block; if the verification passes, the latest block is determined to be an irreversible block.

[0070] The judgment module 530 is used to judge whether the latest block has been processed after the hash check is passed on the latest block.

[0071] In an optional manner, the judgment module 530 is further used to: obtain the block number of the last processed block, and determine whether the block number of the last processed block is equal to the block number of the latest block; if so, it is determined that the latest block has been processed; if not, it is determined that the latest block has not been processed.
