Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the present application, there are transaction pools in each of the blockchain system's blocknodes, which can be updated according to the broadcasted transaction data, so that in many cases, all blockchain nodes have transaction pools storing the same transaction data. In the embodiments of the present application, a first block node and a second block node are used for explanation, the first block node refers to a block node that generates and broadcasts block data to be uplinked, the second node is another block node except the first block node in the block chain system, and the second block node is used as a common node and is mainly used for performing common processing on the block data broadcast by the first block node. For a first blocky node, when it is detected that uplink processing needs to be performed, a transaction data generation blocky is obtained from a transaction pool, and similarly, for a second blocky node, when it is detected that uplink related processing needs to be performed (for example, a certain consensus detection period is entered), transaction data is also obtained from the transaction pool, if the second blocky node successfully obtains transaction data from the transaction pool, it indicates that the first blocky node also obtains the transaction data generation blocky data with a high probability, at this time, after the second blocky node obtains the transaction data, the second blocky node does not generate blocky data corresponding to the obtained transaction data, and may even directly delete the transaction data in the transaction pool of the second blocky node, and the purpose of the transaction data in the second blocky node is only for the second blocky node to determine that a certain first blocky node in the blocky chain system broadcasts the blocky data corresponding to the transaction data, the second block node now needs to listen to the broadcast of the blockchain system and wait for the block data broadcast by the first block node. On the contrary, if the second block node cannot acquire the transaction data from the transaction pool, for the second block node, it may be considered that the first block node also cannot acquire the transaction data at a high rate, and the corresponding block data is not broadcasted, and for the second block node, it may not be necessary to monitor whether the block data is broadcasted on the block chain system. That is, between the first block node and the second block node, the coordination and synchronization of the two works are realized based on the transaction pool.
The coordination and synchronization among the block nodes mentioned in the embodiments of the present invention refer to: synchronously starting to acquire transaction data in the same consensus detection period, and synchronously starting to process respective work flows after acquiring the transaction data, namely: the processing flow of consensus is initiated for the first block node, and the processing flow of consensus is monitored for the second block node to monitor the block data to be consensus.
Referring to the blockchain system shown in fig. 1A, a blockchain system 100 refers to a system for sharing data between blockchain nodes, and the blockchain system may include a plurality of blockchain nodes 101, and the plurality of blockchain nodes 101 may refer to respective clients in the blockchain system. Each blockchain node 101 may receive input information or transaction data and maintain shared data within the blockchain system based on the received input information while operating properly. In order to ensure the information intercommunication in the blockchain system, information connection can exist between each blockchain node in the blockchain system, and the information transmission can be carried out between the blockchain nodes through the information connection. For example, when an arbitrary blocknode in the blockchain system receives input information, other blocknodes in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored in all blocknodes in the blockchain system are consistent.
Each block node in the block chain system has a corresponding block node identifier, and each block node in the block chain system may store block node identifiers of other block nodes in the block chain system, so that the generated block is broadcast to other block nodes in the block chain system according to the block node identifiers of other block nodes. Each block node may maintain a block node identifier list as shown in the following table, and the block node name and the block node identifier may be stored in the block node identifier list correspondingly. The block node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the block node, and table 1 only illustrates the IP address as an example.
| Block node name | Block node identification |
| Block node 1 | 117.114.151.174 |
| Block node 2 | 117.116.189.145 |
| … | … |
| Block node N | 119.123.789.258 |
Each blockchain node in the blockchain system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 1B, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
When each block in the block chain is generated, referring to fig. 1C, when the block node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the block node where the block chain is located respectively sends the newly generated blocks to other block nodes in the block chain system where the newly generated blocks are located according to the block node identifiers of the other block nodes in the block chain system, the other block nodes perform consensus verification on the newly generated blocks, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
As shown in fig. 2, which is a flowchart of a synchronous processing interaction method of a blockchain system according to an embodiment of the present invention, a first blockchain node and a second blockchain node in the blockchain system complete related processing of transaction data through interaction and data processing, transaction pools are stored in the first blockchain node and the second blockchain node, the transaction pools are used for storing transaction data, and the transaction pools are updated according to transaction data broadcast by the blockchain system. The method of an embodiment of the present invention includes the following steps.
When the first block node detects the consensus processing trigger event in S201, the first block node obtains the transaction data to be processed from the transaction pool stored in the first block node. The second block node also performs, in S202, acquiring transaction data from the transaction pool stored in the second block node when the consensus processing trigger event is detected. The common processing trigger event in the first block node and the common trigger event in the second block node are the same event, and may be, for example, a common detection period defined in a blockchain system where the first block node and the second block node are located, and when the first block node and the second block node detect a system time or a system timer counts to enter the common detection period, each of the first block node and the second block node determines that the common processing trigger event is detected and starts to acquire transaction data (the transaction data is also the aforementioned input information) from the transaction pool. The transaction pool comprises transaction data, and the transaction pools in the first block node and the second block node can be updated according to the transaction data broadcast by the blockchain system. In an embodiment, the transaction data included in the transaction pool is transaction data that needs to be processed by the first block node, and the first block node may update the transaction pool according to the transaction data that needs to be processed by the first block node and is broadcast by the blockchain system, and notify the second block node of updating the transaction pool, so that a processing flow after the first block node acquires the transaction data from the transaction pool is different from a processing flow after the second block node acquires the transaction data from the transaction pool.
If the first blocking node and the second blocking node both acquire transaction data from respective transaction pools, it indicates that the first blocking node has to send out the data of the block to be identified in common, and especially for the second blocking node, if the second blocking node also acquires the transaction data, it is basically expected that the first blocking node will send the data of the block to be identified in common, and the monitoring of the block chain system can be started so as to acquire the data of the block to be identified in common without executing other operation processing. Therefore, the first blocking node generates the to-be-identified blocking data according to the to-be-processed transaction data in S203, and broadcasts the to-be-identified blocking data in the blockchain system in S204, so that the to-be-identified blocking data can be sent to the second blocking node. And the second block node starts to monitor the to-be-consensus block data broadcasted in the block chain system at the determined time when the transaction data is acquired in S205, monitors the to-be-consensus block data within the monitoring duration, performs consensus processing on the to-be-consensus block data monitored in S206, and returns consensus result information to the first block node in S207, where the consensus result information includes information indicating success of consensus and information indicating failure of consensus.
If neither the first block node nor the second block node has acquired the transaction data, it indicates that no transaction data currently needs consensus processing, and particularly for the second block node, it may not be necessary to monitor the blockchain system until a next consensus processing trigger event is detected, for example, a next consensus detection period is entered, or it is detected that the transaction pool is updated according to the transaction data broadcasted by the blockchain system.
In an embodiment, please refer to fig. 3, which is a flowchart illustrating a synchronization processing method of a blockchain system according to an embodiment of the present invention, where the method according to an embodiment of the present invention is applied to a blocknode in the blockchain system, specifically, the second blocknode mentioned above, and the method according to an embodiment of the present invention corresponds to the steps executed by the second blocknode according to the embodiment corresponding to fig. 2, and specifically includes the following steps.
S301: when a consensus processing trigger event is detected, acquiring transaction data from a transaction pool stored by the node; the second block node is used for carrying out consensus processing on the to-be-consensus block data after the first block node executes the transaction data. Based on the update of the transaction data of the blockchain network with respect to the first blockchain node, most of the blockchain nodes in the blockchain system of the embodiment of the invention have transaction pools with the same content, and based on the transaction pools, most of the blockchain nodes can realize work synchronization.
S302: and if the transaction data is acquired within the first acquisition duration, monitoring the to-be-identified block data broadcasted in the block chain system at the determined moment of acquiring the transaction data. The first obtaining duration may be determined according to a preset duration, such as a preset duration (e.g., 2s) from the beginning of the transaction data obtaining to the transaction pool. In one embodiment, by detecting a system time or a timer, when the determination time reaches the start time of a consensus detection period, determining to enter the consensus detection period set for the blockchain system, thereby determining that a consensus processing trigger event is detected, where the first acquisition duration is determined according to the start time of the consensus detection period and a preset duration; for example, within 2s of the starting time, the monitoring duration is a time range within the time range of the consensus detection period except for the first acquisition duration; or the monitoring duration is determined according to the time from the acquisition time of the acquired transaction data to the end time of the consensus detection period. That is to say, after acquiring the transaction data, the remaining time of the consensus detection period is the monitoring duration, for example, the consensus detection period is 10 seconds, the first acquisition duration is 2s, and the monitoring duration is determined according to the time at which the transaction data is specifically acquired and the consensus detection period, that is, the second block node starts to acquire the transaction data in the first 2s of the consensus detection period, and if the transaction data is acquired in the 1 st s, the remaining 9s are the second acquisition duration.
S303: if the data of the block to be identified is monitored within the monitoring duration after the transaction data is acquired, carrying out identification processing on the monitored data of the block to be identified; after the transaction data are obtained through judgment, the transaction data needing to be subjected to uplink processing can be obtained through the first block node at a high probability, the second block node monitors the block data to be identified and then processes the block data to be identified according to a common identification processing mechanism, and then returns processing results including results of passing or failing common identification to the first block node, so that the first block node can conveniently perform uplink processing on the block data to be identified.
S304: and if the data of the block to be identified is not monitored in the monitoring time length after the transaction data is acquired, executing identification detection overtime processing. In an embodiment, the timeout processing may be to record a consensus failure in the consensus detection period, or generate null block data and perform consensus on the null block data to end the consensus detection period and enter the next consensus detection period. Before entering the next consensus detection period, the second block node may perform other processing, such as obtaining transaction data from a transaction pool including the transaction data that the second block node needs to perform, and performing uplink processing, i.e., the second block node may be used as the first block node to perform the steps that the first block node needs to perform. In one embodiment, after performing the consensus detection time-out process, a transaction data processing cycle may be entered, and the processing flow of the first block node described in the following embodiments is performed during the transaction data processing cycle.
In one embodiment, the method of the embodiment of the present invention may further include: if the data of the block to be identified is not acquired within the first acquisition duration after the transaction data is acquired, continuing to acquire the data to be transacted from the transaction pool stored in the node within a second acquisition duration, wherein the second acquisition duration is determined according to the first acquisition duration and the ending time of the identification detection period; and if the data to be traded is not acquired in the consensus detection period, executing consensus detection overtime processing. In order to ensure that the second block node and the first block node are synchronized, and avoid the occurrence of a situation that the first block node or the second block node does not acquire transaction data within the first acquisition duration due to a certain abnormal burst, but may acquire the transaction data within a short time after the first acquisition duration, a second acquisition duration may be set in the embodiment of the present application, where the second acquisition duration may be equal to the first acquisition duration, may be smaller than the first acquisition duration, or may be larger than the first acquisition duration, but the total duration of the first acquisition duration and the second acquisition duration may not exceed a duration specified by the consensus detection period. And if the transaction data is acquired within the second acquisition duration, the second block node also enters a monitoring state to monitor the to-be-identified block data broadcast by the first block node in the block chain system.
In one embodiment, if transaction data are acquired from a transaction pool stored in a node and block data to be identified broadcasted in a blockchain system are monitored, whether the acquired transaction data are matched with the block data to be identified is detected; if the transaction data is the transaction data, deleting the acquired transaction data; wherein the matching of the acquired transaction data and the monitored data of the block to be identified comprises: the acquired transaction data is the same as the to-be-processed transaction data included in the to-be-identified block data. Under normal conditions, the transaction pool containing the transaction data is updated in a system-wide synchronous mode, so that for the second block node, whether the first block node can acquire the transaction data can be judged only by judging whether the transaction data can be acquired, at this time, for the second block node, only the transaction data acquired this time needs to be deleted in the transaction pool, and therefore whether new transaction data are acquired or not is judged next time to evaluate the transaction data acquisition condition of the first block node. However, for some small probability situations of abnormal burst which may exist, the transaction data contents stored in the transaction pool in sequence are different, in this case, the embodiment of the present invention adds a determining step to determine whether the acquired transaction data matches with the block data to be commonly identified, if the acquired transaction data matches with the block data to be commonly identified, the acquired transaction data in the second block node transaction pool is deleted according to the normal processing flow, and if the acquired transaction data does not match with the block data to be commonly identified, the abnormal processing flow may be executed, for example, the first acquisition duration and/or the second acquisition duration of the transaction data acquired this time and the monitoring duration are added with abnormal marks, in the subsequent data statistics process, the periods marked with the abnormal marks are not used to update and calculate the common identification detection period, the first acquisition duration, the second acquisition duration and the monitoring duration, or the first acquisition duration and/or the second acquisition duration added with the abnormal marks are deleted in the update statistics stage The duration of the listen, and/or display to a management user of the blockchain system.
In an embodiment, the embodiment of the present invention may further perform data updating in a statistical manner, and the method of the embodiment of the present invention may further include: counting the acquisition counting time length of the acquired transaction data in the transaction pool stored in the node; counting the monitoring statistical time length for acquiring the transaction data in the transaction pool stored in the node, monitoring in the block chain system and acquiring the block data to be identified; and updating the duration corresponding to the consensus detection period according to the obtained statistical duration and the monitoring statistical duration. Specifically, statistics may be performed according to a statistical period, for example, statistics is started after N consensus detection periods to obtain the acquisition statistical duration and the monitoring statistical duration, where N is a positive integer greater than 2; or when the second block node cannot acquire the transaction data any more after acquiring the M transaction data from the transaction pool, starting to count to obtain the acquisition count duration and the monitoring count duration. The obtaining statistical duration and the monitoring statistical duration may be average values of corresponding statistical durations or maximum values. In one embodiment, according to the acquisition statistical time length, updating a first acquisition time length or a second acquisition time length defined in a consensus detection period; and updating the consensus detection period according to the total time length obtained by the obtained statistical time length and the monitoring statistical time length. After the updating is completed, the first block node acquires data from the transaction pool based on the updated first acquisition duration or the updated second acquisition duration and the consensus detection period, and calculates a monitoring duration to monitor the to-be-consensus block data of the first block node broadcasted on the block chain system.
Referring to fig. 4, a flow chart of another synchronization processing method for a blockchain system according to an embodiment of the present invention is shown, where the method according to the embodiment of the present invention is applied to a blockchain node in the blockchain system, where the blockchain node corresponds to the first blockchain node mentioned above, and the method according to the embodiment of the present invention corresponds to the description related to the first blockchain node in the embodiments corresponding to fig. 2 and fig. 3, and specifically includes the following steps.
S401: when a consensus processing trigger event is detected, acquiring transaction data to be processed from a transaction pool stored in the node; and a transaction pool is stored in the block node, the transaction pool is used for storing transaction data, and the transaction pool is updated according to the transaction data broadcasted by the block chain system. The transaction data stored in the transaction pool is data which needs the first block node to perform processing such as consensus, uplink and the like. Based on the update of the transaction data of the blockchain network with respect to the first blockchain node, most of the blockchain nodes in the blockchain system of the embodiment of the present invention have transaction pools with the same content, and based on the transaction pools, most of the blockchain nodes can implement work synchronization.
S402: and if the transaction data to be processed is acquired within the first acquisition duration, generating the block data to be identified according to the transaction data to be processed. The block data to be identified commonly is one of the block data in fig. 1B.
S403: broadcasting the block data to be commonly identified in the block chain system.
S404: and processing the block data to be identified according to the received identification result of each identification node in the block chain system to the block data to be identified.
In one embodiment, when a consensus detection period set for the blockchain system is entered, it is determined that a consensus processing trigger event is detected, and each blockchain node included in the blockchain system acquires transaction data from a respective stored transaction pool within a first acquisition duration of the consensus detection period; the method further comprises the following steps: if the transaction data to be processed is not obtained within the first obtaining duration, the transaction data to be processed is continuously obtained from the transaction pool stored in the node within the second obtaining duration; and if the transaction data to be processed is not acquired in the consensus detection period, generating null block data and broadcasting the null block data in the block chain system. In this embodiment of the present invention, the first obtaining duration adopted in the first block node is equal to the first obtaining duration of the second block node in the above embodiment, the second obtaining duration adopted in the first block node is equal to the second obtaining duration of the second block node in the above embodiment, and the consensus starting period of the first block node is the same as the consensus detecting period of the second block node, where the same includes the same period time, the same period starting time, and the same period ending time.
By adopting the embodiment of the invention, on one hand, the synchronization of consensus related processing can be better ensured among the block nodes in the block chain network, and on the other hand, the block nodes needing to execute consensus can monitor the block chain system in time to acquire the block data to be consensus.
In some other embodiments, the second block node may be in a listening state throughout the consensus detection period, and constantly listen to whether there is corresponding to-be-processed block data in the block chain system.
