Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without creative efforts, are within the protection scope of the invention.
It should be noted that the terms "first," "second," and the like in this application are used merely to distinguish between different devices, modules, or units and are not intended to limit the order or interdependence of functions performed by such devices, modules, or units, but the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The embodiment of the application provides a transaction method based on a blockchain, as shown in fig. 1, specifically comprising the following steps:
s101, grouping operation is performed on the to-be-executed transactions in the transaction set which needs to be executed on the current transaction round, and at least one target transaction group is obtained.
The transaction set to be executed comprises at least one transaction to be executed and an address information set of each transaction to be executed; each set of address information for a transaction to be performed includes: transaction party address information, transacted party address information, and contract address information; the transactions to be executed in the target transaction group are ordered according to the transaction index of the transactions to be executed; the address information set of the to-be-executed transaction in each target transaction group has no intersection with the address information sets of the to-be-executed transactions in other target transaction groups.
It will be appreciated that when the transaction device is first started, the transaction group dependency library in the transaction device needs to be initialized.
The transaction grouping dependency library consists of a plurality of dependency tables, and the dependency variables of the transaction grouping dependency library are as follows: transaction party address information, transacted party address information, and contract address information for a transaction. And the dependent variables in each set of dependency tables must be related.
It should be noted that, if the current transaction round is the first transaction round, the transaction set to be executed, the front-round transaction set to be executed, the applicable transaction set, the pending transaction set, and the maximum serial number variable of the currently adopted transaction in the block need to be initialized.
Wherein the transaction in the pending transaction set is a transaction execution result in a previous transaction round which does not need to be re-executed in the current transaction round and can be directly multiplexed, but it cannot be determined whether the transaction is a accepted transaction.
It will be appreciated that the set of transactions to be performed includes at least one transaction group to be performed, the set of front-wheel transactions to be performed includes at least one front-wheel transaction group to be performed, the adaptable set of transactions includes at least one adaptable transaction group, and the pending set of transactions includes at least one pending transaction group. The set of transactions that need to be performed may be denoted executing Transactions { }, the set of front-wheel transactions that need to be performed may be denoted presroups { }, the set of admissible transactions may be denoted accept Transactions { }, the set of pending transactions may be denoted pending Groups { }, and the maximum sequence number variable in the block for the currently admissible transaction may be denoted lastAccept TrxIndex.
Specifically, executingtransactions= { transactions in block }, pregroups= accept Transactions =recirculating groups=empty set, lastAccept TrxIndex is-1.
Optionally, in another embodiment of the present application, an implementation of step S101, as shown in fig. 2, includes:
s201, acquiring a transaction set which needs to be executed in the current transaction round.
The transaction set to be executed comprises at least one transaction to be executed and address information sets of each transaction to be executed.
S202, confirming that each two address information sets of the transactions to be executed have intersection transactions among all the transactions to be executed.
For example: and if the address information of the transaction party of the transaction A to be executed is the same as that of the transaction party of the transaction B to be executed, confirming that the intersection exists between the address information set of the transaction A to be executed and the address information set of the transaction B to be executed.
It is understood that only when the address information of the transaction party of the transaction to be executed a and the transaction party of the transaction to be executed B, and the contract address information of the transaction to be executed a and the transaction to be executed B are different, it is confirmed that the address information set of the transaction to be executed a and the address information set of the transaction to be executed B have no intersection.
S203, in all the transactions to be executed, the transaction to be executed with the intersection set of the address information sets of the transaction to be executed is used as the same target transaction group.
It will be understood that when there is an intersection between the set of address information of the to-be-executed transaction a and the set of address information of the to-be-executed transaction B, and there is an intersection between the set of address information of the to-be-executed transaction C and the set of address information of the to-be-executed transaction B, then the to-be-executed transaction a, the to-be-executed transaction B, and the to-be-executed transaction C are the same target transaction group.
It should be noted that, after grouping the transactions to be executed, it is also required to confirm whether the generated target transaction group is the first generated target transaction group. Specifically, if the target transaction group is the first generated transaction group, determining whether the first generated target transaction group conflicts with the transaction group in the transaction group dependency library; if the first generated transaction group is judged to have conflict with the transaction groups in the transaction group dependence library, combining the two conflicting transaction groups to obtain a final target transaction group, and if the first generated transaction group is judged to have no conflict with the transaction groups in the transaction group dependence library, not processing.
S102, judging whether the last executed grouping operation is the first grouping operation executed for the current transaction round.
Specifically, if it is determined that the last packet operation performed is not the first packet operation performed on the current transaction round, step S103 is performed. If it is determined that the last grouping operation is the first grouping operation performed on the current transaction round, because of the grouping manner adopted in step S101, the address information set of the transaction to be performed in each target transaction group obtained after grouping does not have an intersection with the address information sets of the transaction to be performed in other target transaction groups, so that each target transaction group can be directly processed in parallel.
It should be noted that one or more transactions to be executed in the target transaction group are executed serially. Before executing the transaction to be executed, the dependency field of each transaction to be executed needs to be cleared, and during the execution process of the transaction to be executed, related addresses need to be stored into the dependency field of the transaction to be executed when operations such as reading and writing contract variables, account addresses and the like are performed each time.
Optionally, in another embodiment of the present application, an implementation after parallel processing of each target transaction group includes:
Judging whether a pending transaction set in a previous transaction round is empty or not; wherein the set of pending transactions consists of at least one pending transaction.
Specifically, if it is determined that the pending transaction set in the previous transaction round is empty, assigning an execution result of the transaction to be executed in each target transaction group in the current transaction round to the transaction set to be executed, and returning to the execution step S101; if it is determined that the set of pending transactions in the previous transaction round is not empty, merging the set of pending transactions with the set of pending transactions in each target transaction group in the current transaction round, assigning the set of pending transactions to the set of transactions to be executed, and returning to the execution step S101.
S103, determining at least one target transaction in the current transaction round.
Wherein the target transaction is an adoptable transaction or a pending transaction or a transaction requiring re-execution.
It should be noted that, after determining the admissible transaction, the admissible transaction is added to the admissible transaction set, after determining the pending transaction, the pending transaction is added to the pending transaction set, after determining the transaction needing to be re-executed, the transaction needing to be re-executed is added to the transaction set needing to be executed in the next transaction round, after determining at least one target transaction in the current transaction round, the maximum serial number variable of the currently admissible transaction in the block is also required to be calculated, and the transaction set after the maximum serial number variable of the currently admissible transaction in the block is marked as the transaction set needing to be executed in the next round.
Optionally, in another embodiment of the present application, an implementation of step S103, as shown in fig. 3, includes:
s301, determining a target transaction group with conflict transactions.
The transactions to be executed in the target transaction group are ordered from small to up to small according to the transaction index of the transactions to be executed.
It should be noted that all transactions in the target transaction group must belong to the same group in the pre Groups or the pending Groups. If all transactions within a portion of the target transaction group are from different pre Groups or pending Groups in the target transaction set to which the target transaction group belongs, then it is indicated that the transactions are related and cannot be performed in parallel, i.e., there is a conflicting transaction. I.e. the resulting target transaction group for the current packet is incorrect.
Referring to fig. 4, taking a target transaction group 1 in the target transaction set as an example, a first transaction trx 1 to be executed, a second transaction trx 2 to be executed, and a third transaction trx 3 to be executed in the target transaction group 1 are all from the group 1 in the pre Groups or the pending Groups; the fourth to-be-executed transaction trx 4 in the target transaction group 1 is from the group 3 in the presroups or the pending Groups, which indicates that the target transaction group 1 in the target transaction set is a conflicting transaction.
Specifically, transactions within the target transaction group are from different target transaction Groups of pre-Groups or pending Groups as target transaction Groups for which conflicting transactions exist.
S302, for each target transaction group with conflict transactions, determining conflict indexes of the target groups with conflict transactions.
The conflict index is a transaction index value of a first conflict transaction to be executed in a target transaction group with conflict transactions.
Referring to fig. 4, continuing the above example, the transaction index value of the fourth transaction trx4 to be executed in the target transaction group 1 is used as the conflict index of the target transaction group 1.
S303, determining the minimum value of all conflict indexes of the target groups with conflict transactions as target conflict indexes.
S304, determining the transaction to be executed with the transaction index value smaller than the target conflict index as the applicable transaction.
S305, determining that the transaction index value of the transaction to be executed is larger than or equal to the target conflict index and does not belong to the transaction to be executed in the pending transaction set as the transaction needing to be executed again.
S306, determining the transaction to be executed with the transaction index value larger than or equal to the target conflict index in the target transaction group without conflict transaction as the transaction to be determined.
S104, judging whether each target transaction is adopted.
Specifically, if it is determined that each target transaction is adopted, step S105 is executed; if it is determined that any target transaction is not accepted, step S106 is performed.
S105, ending the transaction of the current transaction round.
S106, taking the unadopted target transaction as a new transaction to be executed.
It will be appreciated that in order to make the data in the dependency library richer and more accurate, in another embodiment of the present application, an implementation after step S106 further includes:
storing the address information set of the unadopted target transaction and the address information set of the transaction conflicting with the unadopted target transaction into the same dependency table in the transaction grouping dependency library.
As can be seen from the above solution, in the blockchain-based transaction method provided by the present application, not only is the transaction to be executed performed in a grouping manner, so as to obtain at least one target transaction group, but also each target transaction group is directly processed in parallel when the last performed grouping operation is the first grouping operation performed on the current transaction round, so that the efficiency of executing the blockchain transaction is improved; and when the last executed grouping operation is not the first grouping operation executed by the current transaction round, determining at least one target transaction in the current transaction round, wherein the target transaction is an adoptable transaction or a pending transaction or a transaction needing to be re-executed, taking the unadopted target transaction in the current transaction round as a new transaction to be executed, and performing the grouping operation of the next transaction round, wherein the grouping operation is performed by classifying the transactions according to the transaction state, and only re-grouping part of the transactions, thereby further improving the execution efficiency of the blockchain transaction.
Another embodiment of the present application provides a transaction device based on blockchain, as shown in fig. 5, specifically including:
a grouping unit 501, configured to perform a grouping operation on a transaction to be performed in a transaction set that needs to be performed in a current transaction round, so as to obtain at least one target transaction group.
The address information set of the to-be-executed transaction in each target transaction group is not intersected with the address information sets of the to-be-executed transactions in other target transaction groups.
