Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of an operation method of an offline blockchain system according to a first embodiment of the present invention, where the method is applied to an offline transfer of online traffic data in a decentralized system. The method is executed by an operating device of the offline blockchain system, and the device is realized by software and/or hardware and is specifically configured in electronic equipment bearing blockchain nodes, or can be configured in other electronic equipment to provide online flow data for the offline blockchain system. The block link point is a block link node in the offline block link system.
A method for operating an offline blockchain system as shown in fig. 1 includes:
s110, acquiring the full-quantity ordered transaction request stored in the block from the chain link point of the block on the line.
The block link point on the line can be understood as a block link point in the block chain system on the line generating the traffic data. Transaction requests may be understood as transaction requests that are processed in an inline blockchain system, which are typically initiated by user control for processing some specific business function, such as e-money transaction requests, etc.
Optionally, the full-amount ordered transaction request stored in the block is obtained from any one online blockchain node in the online blockchain system. Or optionally, the full-quantity ordered transaction requests stored in each stage of the block are synchronously acquired in segments from at least two online block chain nodes in the online block chain system respectively; and summarizing the full-scale ordered transaction requests of each stage according to the original sequence in the block to obtain the full-scale ordered transaction requests. Or optionally, synchronously acquiring full-quantity ordered transaction requests stored in the blocks from at least two online blockchain nodes in the online blockchain system; when all the transaction requests in the full-scale ordered transaction requests of all the online block chain nodes are consistent, taking the full-scale ordered transaction request in any one online block chain node as a finally obtained full-scale ordered transaction request; and when at least one transaction request in the full-quantity ordered transaction requests of at least one online blockchain node is inconsistent with the corresponding transaction requests in the full-quantity ordered transaction requests of other online blockchain nodes, re-acquiring the full-quantity ordered transaction requests from other online blockchain nodes in the online blockchain system. The online block link point is preferably a trust node in an online block link network, for example, an online block link node with the highest data acquisition frequency, the highest computational effort, or the highest verification passing rate after processing a transaction request.
It should be noted that the fully ordered transaction requests may be understood as transaction requests included in each block corresponding to the starting block and the last added block in the online block chain system, and the transaction requests are sequentially ordered according to the storage order in the block chain.
It is understood that, in order to avoid the situation that the association relationship between the acquired transaction request and the transaction request which is not acquired causes all or part of the acquired transaction request to be invalid, the creation block is used as the starting block of the acquired transaction request; in order to avoid poor user experience caused by data transmission interruption or data blockage due to excessive data during a single transaction request acquisition, a batch acquisition mode is preferably adopted. Illustratively, from the online block link point, starting from the created block, the full-scale ordered transaction requests stored in the block are acquired batch by batch, the height of the ending block of the current batch is recorded at the end of each batch acquisition, and the transaction requests in the blocks of the next batch are acquired from the height of the ending block of the last time when the next batch acquisition starts.
In an alternative embodiment, the full amount of ordered transaction requests stored in a block may be obtained from block links stored at block link points on the line. Illustratively, consecutive blocks are obtained from block chain nodes on the line, and the obtained transaction requests are respectively analyzed from each block and summarized as full-scale ordered transaction requests.
Specifically, all blocks between the starting block and the ending block are sequentially acquired from the block chain nodes on the line, in the process of acquiring each block or after acquiring all blocks, the transaction requests are respectively analyzed and acquired from each block, and the analyzed transaction requests are sequentially summarized according to the storage sequence in the block chain to obtain the full-quantity ordered transaction requests.
In another alternative embodiment, the full amount of ordered transaction requests stored in the block may be obtained from an inline block link point, which may be locally stored block chain data. Illustratively, the full number of ordered transaction requests stored in the node localization database, already stored in the block, are retrieved from the online block link point.
Specifically, the ordered transaction requests stored in each block from the start block to the end block are directly obtained from the node localization database of the link point of the block on the line.
In another alternative embodiment, the full-size ordered transaction request stored in the block is obtained from an online block link point, and may also be obtained from a block chain of online block link points based on locally storing data at the online block link point. Illustratively, acquiring a storage address corresponding to a transaction request stored in each block from a starting block to an ending block in a block chain from an online block link point localization database; and acquiring corresponding transaction requests from corresponding storage addresses in each block in sequence, and summarizing the transaction requests to be used as full-quantity ordered transaction requests.
Since transaction requests that can be stored in a block have been processed and accepted by many nodes of the blockchain network, ordered transaction requests are efficiently executed without the existence of invalid, unexecutable transaction requests.
And S120, performing data cleaning on the transaction request to meet the operation requirement of the offline block chain system.
The electronic device stores the operation requirement of the offline blockchain system in advance in a local storage device or a cloud terminal associated with the electronic device. Accordingly, the electronic device may obtain the operation requirement locally, in a storage device associated with the electronic device, or in a cloud; determining a reference condition required to be met by a transaction request executed by the offline blockchain system according to the operation requirement; and performing data cleaning on the acquired full-quantity sequence transaction requests according to the reference condition so as to correspondingly edit and replace or directly delete the transaction requests which do not meet the condition according to the operation requirement.
It will be appreciated that to facilitate reuse of the retrieved transaction requests, the retrieved full-scale ordered transaction requests may also be backed up first before data cleansing of the transaction requests.
And S130, sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-scale ordered transaction requests.
Because the cleaning process of the transaction request is completely determined according to the operation requirement of the offline blockchain system, the cleaned transaction request can be directly used as input data to be sent to the offline blockchain system. Considering the incidence relation among the transaction requests in the block chain, when the cleaned transaction requests are sent to the offline block chain system, the transaction requests need to be sent according to the sequence of the full-quantity ordered transaction requests, and further the condition that the transaction requests are invalid due to the change of the sequence of the transaction requests is avoided.
The cleaned transaction request may be a transaction request corresponding to an in-line blockchain system. Certainly, in order to meet the requirement of the offline blockchain system on the quantity of input data, the cleaned transaction requests of the at least two online blockchain systems can be sent to the offline blockchain system to be executed according to the sequence of the full-quantity ordered transaction requests, and only the transaction requests corresponding to any two offline blockchain systems need to be ensured to have no correlation relationship with each other.
The embodiment of the invention acquires the full quantity of ordered transaction requests stored in the block from the on-line block chain node, and performs data cleaning on the transaction requests to meet the operation requirement of the off-line block chain system; and sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-quantity ordered transaction requests. According to the technical scheme of the embodiment of the invention, the transaction requests of the online block chain nodes are acquired in a full-quantity and orderly manner, so that the condition that part of the transaction requests cannot take effect in the online block chain system due to neglecting the incidence relation among the transaction requests is avoided, the online flow data in the decentralized system is effectively extracted, and the guarantee is provided for the offline transfer of the online flow data.
Example two
Fig. 2 is a flowchart of an operation method of an offline blockchain system according to a second embodiment of the present invention. The embodiment of the invention is optimized and improved on the basis of the technical scheme of each embodiment.
Further, the operation of "performing data cleaning on the transaction request to meet the operation requirement of the offline block chain system" is subdivided into "if a user online account appears in the transaction request, acquiring a corresponding offline account, and changing an online account address in the transaction request into a corresponding offline account address", so that when the transaction request appears in the user online account, the traffic data corresponding to the transaction request related to the user online account in the online block chain system can be effectively transferred into the offline block chain system.
A method for operating an offline blockchain system as shown in fig. 2 includes:
s210, acquiring the full-quantity ordered transaction request stored in the block from the chain link point of the block on the line.
The transaction request includes a transfer transaction request, such as a transfer-in request, a transfer-out request, a conversion request, an account freezing request and the like of currency elements circulating in the blockchain network. The transfer transaction request includes the transfer-in account address and the transfer-out account address for the monetary element. Generally, an account is determined and generated based on a random number (for example, timestamp information, machine device identification of an account user, and the like) by a cryptographic algorithm, and is managed by an asymmetric key pair, wherein a public key of the asymmetric key pair is an account address, and a private key is reserved by an account owner.
S220, if the online account of the user appears in the transaction request, the corresponding offline account is obtained, and the online account address in the transaction request is changed into the corresponding offline account address.
And the on-line account of the user corresponds to the transfer-in account and the transfer-out account of the monetary elements in the transfer transaction request. Because the random numbers used by the cryptographic algorithm are different when the account is generated, the online account of the user cannot be directly copied to the offline for the offline blockchain system to use, and therefore, the online account address in the online blockchain system needs to be additionally mapped to the offline blockchain system.
Specifically, whether the online account has a corresponding offline account is inquired, and if yes, the online account address in the transaction request is changed into the corresponding offline account address; and if not, establishing an offline account based on the cryptographic algorithm, establishing a corresponding relation between the newly established offline account and the online account, and replacing the online account address in the transaction request with the newly established offline account address.
Generally, the number of online accounts is identical to that of offline accounts, and the online accounts and the offline accounts correspond to each other one by one. Of course, in order to meet the special requirements of the offline blockchain system (for example, performing performance test on the offline blockchain system), some other accounts, such as miners' accounts in the offline blockchain system, may also be added to the offline blockchain system.
And S230, sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-scale ordered transaction requests.
According to the embodiment of the invention, the cleaning operation on the transaction request is refined into the mode that when the user online account appears in the transaction request, the corresponding offline account is obtained, and the online account address in the transaction request is changed into the corresponding offline account address, so that when the user online account appears in the transaction request, the flow data corresponding to the transaction request related to the user online account in the online block chain system can be effectively transferred to the offline block chain system, and the invalid extraction of the flow data is avoided.
EXAMPLE III
Fig. 3 is a flowchart of an operation method of an offline blockchain system according to a third embodiment of the present invention. The embodiment of the invention is optimized and improved on the basis of the technical scheme of each embodiment.
Further, the operation of 'performing data cleaning on the transaction request to meet the operation requirement of the offline blockchain system' is refined into 'if the transfer transaction request excited by the accounting right of the block chain points appears in the transaction request, deleting the transfer transaction request from the full-quantity ordered transaction request' so as to avoid the condition that the data in the offline blockchain system is inconsistent with the data in the online blockchain system due to the existence of the transfer transaction request excited by the accounting right.
A method for operating an offline blockchain system as shown in fig. 3 includes:
s310, acquiring the full-quantity ordered transaction request stored in the block from the chain link point of the online block.
S320, if the transfer transaction request stimulated by the block link point accounting right appears in the transaction request, deleting the transfer transaction request from the full-volume ordered transaction request.
When the online block link points in the online block chain system compete for the accounting right and perform a certain mining operation as the online block generation nodes, the online block chain system generates an online transfer transaction request for accounting right activation, so that a set number of online activation elements are transferred from a specific account (e.g., an online system account) to the online block generation node account.
When an offline blockchain node in the offline blockchain system serves as an offline blockchain generation node to perform a corresponding offline mining operation, the offline blockchain system will also generate a corresponding offline accounting transaction request for accounting right incentive, so that a set number of offline incentive elements are transferred from a corresponding specific account (e.g., an offline system account) to the offline blockchain generation node account. However, the acquired transaction requests of the online blockchain system also include online transfer transaction requests corresponding to online mining operations, which inevitably results in repeated execution of offline blockchain systems on offline transfer transaction requests corresponding to the online transfer transaction requests, and causes inconsistency between data in the offline blockchain system and the online blockchain system.
In order to avoid repeated execution of the transfer transaction request generated by the offline blockchain node and the transfer transaction request contained in the online blockchain system, after the full-amount ordered transaction request is acquired from the online blockchain node, the transfer transaction request excited by the bookkeeping right of the blockchain node in the acquired transaction request needs to be searched, and after the transfer transaction request related to the bookkeeping right excitation is searched, the transfer transaction request is directly and correspondingly deleted from the full-amount ordered transaction request.
Optionally, the search operation for the transfer transaction request stimulated by the accounting right may be to acquire an element of the current transaction request and transfer the element into an account; transferring the acquired elements into an account and comparing the acquired elements with a system account in an online block chain system; and if the comparison result is the same, determining that the current transaction request is the transfer transaction request stimulated by the accounting right.
Or alternatively, the lookup operation for the transfer transaction request stimulated by the accounting right may be to obtain an element of the current transaction request to transfer out of the account; and if the acquired element transfer-out account has the identity of the miners, determining that the current transaction request is the transfer transaction request stimulated by the accounting right. Specifically, the account corresponding to the block generation node may be determined to be a miner account in the block header.
S330, sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-scale ordered transaction requests.
According to the embodiment of the invention, the data request operation of the transaction request is refined into the transfer transaction request excited by the accounting right of the block chain nodes in the transaction request, and the transfer transaction request is deleted from the full-quantity ordered transaction request, so that the request that the data of the offline block chain system is inconsistent with the data of the online block chain system due to repeated execution of the transfer transaction request in the offline block chain system is avoided.
Example four
Fig. 4 is a flowchart of an operation method of an offline blockchain system according to a fourth embodiment of the present invention. The embodiment of the invention is optimized and improved on the basis of the technical scheme of each embodiment.
Further, in the process of executing the operation of sending the cleaned transaction requests to the offline block chain system for execution in the order of the full-quantity ordered transaction requests, additionally operating the operation of performing difference processing on the absolute block height and the initiated block height when the transaction requests are initiated on the line to obtain a height difference if the absolute block height exists in the current transaction request to be sent as an execution parameter; summing the height difference with a current offline block height of an offline block chain system; and replacing the absolute block height' in the current transaction request to be sent by the summation result value so as to avoid the condition that the data in the offline block chain system and the online block chain system are inconsistent due to the existence of the transaction request associated with the absolute block height.
A method for operating an offline blockchain system as shown in fig. 4 includes:
s410, acquiring the full-quantity ordered transaction request stored in the block from the chain link point of the block on the line.
And S420, performing data cleaning on the transaction request to meet the operation requirement of the offline block chain system.
And S430, sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-scale ordered transaction requests.
S440, if the absolute block height exists in the current transaction request to be sent as an execution parameter, performing difference processing on the absolute block height and the initiated block height when the transaction request is initiated on the line to obtain a height difference.
For example, when the online blockchain system uses a DPOS (distributed Proof of trust) consensus mechanism, all online blockchain nodes are proxied to confirm the blocks and maintain the ordered operation of the online blockchain system by voting a part of representative nodes through each online blockchain node in the online blockchain system. In the voting process, usually the freezing of the incentive elements is accompanied in the designated block height range, and in the transaction request corresponding to the voting process, absolute block height values of the incentive elements freezing, such as the freezing starting block height and the freezing ending block height, or the freezing starting block height and the freezing continuing block height, must exist.
For another example, when the transaction request is a request to initiate a bonus competition event, there must be a freezing of the competition incentive elements within the absolute height block. For another example, when the transaction request is a product transfer request between the seller and the buyer, and when the seller is not completely transferred to the buyer, the money elements paid by the buyer may be temporarily frozen within the absolute height block in the transaction request in order to reduce the transaction risk of the buyer.
In the above various application scenarios and similar application scenarios, there are cases where the absolute block height is used as an execution parameter in the transaction request. Then, when the obtained full-scale ordered transaction request is executed in the block chain system under the line, and when the block height is accumulated based on the existing block height of the block chain system under the line, the block height of the transaction request in the block chain system under the line and the corresponding block height of the transaction request in the block chain system above the line have a certain height difference.
As another example, the transaction requests actually generated in the online block chaining system may be sparse, such as at night when user activity is necessarily lower than the activity of the user generating the transaction requests during the day, which results in transaction requests that are not actually processed in many blocks. Then, in order to make efficient use of the offline blockchain system, it is not usually performed completely according to the generation time interval of the online transaction requests, for example, the transaction requests generated within 1 month of the online transaction requests, and the control may complete the processing within several days in the offline blockchain system.
In order to avoid the block offset generated when the transaction request is executed in the offline block chain system due to the existence of the height difference, the absolute block height in the corresponding transaction request in the online block chain system may be differentiated from the block height when the transaction request is initiated on the line, and the obtained difference may be used as the height difference. Illustratively, the difference between the height of the freeze-terminated block when the excitation element is frozen and the height of the freeze-initiated block is obtained.
S450, summing the height difference with the current offline block height of the offline block chain system.
The obtained height difference is summed with the current offline block height of the offline block chain system, and the absolute block height in the transaction request is replaced by the summation result value subsequently, so that the mapping of the absolute block height of the online block chain system in the offline block chain system is realized, and the continuity and the accuracy of the offline block chain system in executing the full-scale ordered transaction request are ensured.
And S460, replacing the absolute block height in the current transaction request to be sent with the summation result value.
In the embodiment of the invention, in the process of sending the cleaned transaction requests to the offline block chain system for execution according to the sequence of the full-quantity ordered transaction requests, the replacement operation of the absolute block height contained in the transaction requests to be sent is added, so that the mapping of the absolute block height of the online block chain system to the offline block chain system is realized, the continuity and the accuracy of the offline block chain system in executing the full-quantity ordered transaction requests are ensured, and the condition that the data in the offline block chain system is inconsistent with the data in the online block chain system due to the existence of the transaction requests associated with the absolute block height is avoided.
EXAMPLE five
Fig. 5A is a flowchart of an operation method of an offline blockchain system according to a fifth embodiment of the present invention. The embodiment of the invention is optimized and improved on the basis of the technical scheme of each embodiment.
Further, the operation "the cleaned transaction requests are sent to the offline block chain system for execution according to the sequence of the full-quantity ordered transaction requests", and the operation "the cleaned transaction requests are sent to the sandbox system serving as the offline block chain system for execution according to the sequence of the full-quantity ordered transaction requests and the test pressure requirements", so that the online block chain system with the changed version is subjected to system level test through the sandbox system of the offline block chain system. Illustratively, the version change of the online blockchain system may be an online blockchain system version upgrade, such as an upgrade of an intelligent contract in the online blockchain system, code that is modified to optimize performance, or system architecture adjustment, etc.
To clearly understand the technical solution of the embodiment of the present invention, a lower block chain system is first described.
Referring to the structural composition diagram of the on-line blockchain system and the off-line blockchain system shown in fig. 5B, the off-line blockchain system 52 may have the same or similar hardware composition as the on-line blockchain system 51 corresponding to the on-line blockchain point. For example, the number of offline blockchain nodes included in the offline blockchain system is completely the same as the number of online blockchain nodes included in the online blockchain system, and the hardware configuration of each offline blockchain node is also completely the same as that of the corresponding online blockchain node. For another example, the number of offline blockchain nodes included in the offline blockchain system is set in equal proportion to the number of online blockchain nodes of different hardware configurations in the online blockchain system. It will be appreciated that the proportions set should be subject to the requirements of the test.
The offline blockchain system performs data processing through a sandbox environment of the electronic device bearing the offline blockchain nodes. Three module drainage modules (dumper), cleaning modules (txclean) and pressure modules (loader) are arranged in the sandbox system.
A method for operating an offline blockchain system as shown in fig. 5A includes:
s510, acquiring the full-quantity ordered transaction request stored in the block from the link point of the block on the line.
The flow guiding module obtains the continuous blocks from any node or a trusted node in the chain link points of the blocks on the line, and analyzes and obtains the transaction requests from each block to obtain the full-scale ordered transaction requests.
Optionally, the flow guiding module obtains continuous blocks from the on-line block chain node, and analyzes and obtains the transaction requests from each block respectively, and summarizes the transaction requests as full-scale ordered transaction requests. Or optionally, the drainage module obtains the full-scale ordered transaction requests stored in the stored block from the online block link point in the node localization database.
In order to avoid the situation that the association relationship between the acquired transaction request and the transaction request which is not acquired causes all or part of the acquired transaction request to be invalid, the acquisition of the transaction request is preferably performed from the foundational block. In order to avoid poor user experience caused by data transmission interruption or data blockage due to excessive data during a single transaction request acquisition, a batch acquisition mode is preferably adopted. For example, the drainage module may obtain the full amount of ordered transaction requests stored in the blocks batch by batch starting from the created block from the block link point on the line, record the height of the termination block of the current batch at the end of each batch acquisition, and obtain the transaction requests in the blocks of the next batch starting from the height of the last termination block at the beginning of the next batch acquisition.
S520, performing data cleaning on the transaction request to meet the operation requirement of the offline block chain system.
And the cleaning module is used for cleaning data of the transaction request acquired by the drainage module so as to meet the operation requirement of the offline block chain system to be tested.
Optionally, when the online account of the user appears in the transaction request, the cleaning module acquires the corresponding offline account, and changes the address of the online account in the transaction request into the address of the corresponding offline account.
Or optionally, the cleaning module deletes the transfer transaction request from the full-volume ordered transaction request when the transfer transaction request excited by the block link point accounting right appears in the transaction request.
And S530, sending the cleaned transaction requests to a sandbox system serving as a offline block chain system for execution according to the sequence of the full-scale ordered transaction requests and the test pressure requirements.
And the pressure sending module sends the transaction requests cleaned by the cleaning module to a sandbox system in the offline blockchain system according to the original sequence in the online blockchain system and the frequency and the number corresponding to the test pressure requirement, so that the sandbox system of the offline blockchain system can execute the transaction requests, and the online blockchain system with the changed version can be tested in a system level mode. The test pressure requirement can be a high-pressure test or a low-pressure test, and can be changed according to actual conditions. It is understood that, when the test pressure requirement changes, the sending module may determine the frequency and the number of the transaction requests sent to the sandbox system according to the changed test pressure requirement, so as to match the transmission process of the transaction requests with the test pressure requirement.
In order to ensure the continuity and the transfer of transaction requests executed by a sandbox system and avoid the condition that data in an offline block chain system is inconsistent with data in an online block chain system due to the existence of the transaction requests associated with the absolute block heights, a pressure sending module can also identify whether the execution parameters of the absolute block heights exist in the current transaction requests to be sent when the transaction requests are sent to the sandbox system in sequence; when recognizing that the absolute block height exists in the current transaction request to be sent as an execution parameter, performing difference processing on the absolute block height and the initiated block height when the transaction request is initiated on the line to obtain a height difference; summing the height difference with a current offline block height of the offline block chain system; and replacing the absolute block height in the current transaction request to be sent by the summation result value.
It can be understood that when the number of the cleaned transaction requests cannot meet the test pressure requirement of the equipment system, for example, when the data amount of the transaction requests is insufficient during a high-pressure test, the cleaned transaction requests of the block chain system on other lines may be additionally supplemented, and it is only necessary to ensure that no conflict occurs between the acquired cleaned transaction requests of the block chain system on other lines and the transaction requests corresponding to the block chain system on the current line. Of course, the cleaning process of the transaction request corresponding to the additionally supplemented other online blockchain system should be consistent with the cleaning process of the transaction request corresponding to the current online blockchain system.
According to the embodiment of the invention, the operation method of the offline block chain system is applied to the application scene of the sandbox system test, and the sandbox system of the offline block chain system is used for performing the system level test on the online block chain system with the changed version, so that the situation that the flow extraction in the decentralized system cannot be fully quantized due to the fact that the decentralized system cannot directly adopt the centralized system to perform data mirroring by using an online flow copying tool because of different pressure sources is avoided, the effective extraction of the online flow data in the decentralized system is realized, and various problems caused when the offline centralized system is online in advance after the version is changed are effectively intercepted, and the smooth operation of the decentralized system after the online is ensured.
