All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.

Fig. 1 is an application scenario schematic diagram of a transaction processing method based on blockchain, provided in an embodiment of the present application, as shown in fig. 1, where the scenario includes: a terminal device of a first user and at least one blockchain node (only one shown in fig. 1) accessing the blockchain; the terminal equipment is a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like.

Specifically, when a first user wants to conduct transaction processing of a transaction to be processed through a blockchain, operating terminal equipment of the first user to edit transaction information, responding to the transaction operation of the first user, and sending a transaction request to a blockchain link point according to the acquired transaction information; the transaction to be processed can be an instant transaction, a delayed transaction, a periodic circulation transaction and the like. When the blockchain node receives a transaction request sent by a first user, if the transaction to be processed is determined to be a delay transaction or a periodic cycle transaction according to transaction information in the transaction request, determining a target transaction queue for storing the transaction information in n preset transaction queues, and storing the transaction information to the determined target transaction queue; if the preset transaction packaging conditions are met, detecting target transaction information meeting the transaction processing conditions in each transaction queue based on the first intelligent contract; and carrying out transaction processing according to the target transaction information, and carrying out transaction packaging processing according to the first processing result information of the transaction processing to obtain a corresponding block. Other transactions shown in fig. 1, such as instant transactions, etc. Therefore, through presetting a plurality of transaction queues and storing transaction information of delayed transaction or periodic cycle transaction through the transaction queues, target transaction information meeting transaction processing conditions in the transaction queues can be detected when the preset transaction packaging conditions are confirmed to be met, and transaction processing and packaging processing are carried out according to the target transaction information; the method realizes the related processing of the delay transaction and the periodic circulation transaction, enriches the transaction types and the processing modes of the transaction in the blockchain, and can meet the diversified transaction processing requirements of the current user.

Based on the above application scenario architecture, the embodiment of the present application provides a transaction processing method based on a blockchain, and fig. 2 is a flow chart of the transaction processing method based on the blockchain provided in the embodiment of the present application, where the method in fig. 2 can be executed by the blockchain node in fig. 1, as shown in fig. 2, and the method includes the following steps:

step S102, receiving a transaction request sent by a first user; wherein the transaction request includes transaction information for the transaction to be processed;

the transaction information may include a transaction name, a transaction parameter, a transaction type, contract address information and contract identification information of a second intelligent contract corresponding to the transaction to be processed, signature data of the first user, user information of the first user, and the like. Where transaction names such as transfer transactions, statistical transactions, etc. The transaction parameters may vary from transaction to transaction, such as in a transfer transaction, and may include transfer-out account information, transfer-in account information, transfer amount, and the like. The transaction type is used to characterize the type of transaction to be processed, such as instant transaction, delayed transaction, periodic recurring transaction, etc. Wherein the instant transaction is an immediately executed transaction. The delayed transaction is a transaction executed when a specified transaction execution condition is reached, such as a transaction executed when a specified transaction execution time or a specified transaction execution block height is reached, etc.; when the transaction to be processed is a delayed transaction, the transaction information may further include transaction execution condition information; if the current block height of the blockchain is 1000 blocks, the transaction information includes transaction execution condition information when the block height is 1050, and the like. The periodic recurring transactions are transactions executed in a plurality of cycles according to a specified period, such as transactions executed once every 2 days, transactions executed every 200 blocks newly added, and the like. The second smart contract may be a smart contract provided by a service provider for transaction processing of the corresponding transaction; each second smart contract has unique contract address information, and the contract identification information can change along with the change (such as updating and the like) of the second smart contract; contract identification information such as hash value, version number, etc. of the second smart contract; when the contract identification information is a version number, it may be preset that the version number is sequentially incremented when the second smart contract is changed, such as V1.0, V1.1, V1.2, etc. The signature data may be data obtained by performing signature processing on the specified data according to a private key of the first user, where the specified data may be set by itself in actual application according to needs, and each data other than the signature data in the transaction information is entered to perform signature and the like. First user information such as a first user identification, etc.

Further, when the transaction to be processed is a delayed transaction or a periodic recurring transaction, the transaction to be processed may include a plurality of first transactions having a dependency relationship that may be reflected by a priority of transaction processing; accordingly, the transaction information may also include priority information. As an example, the pending transactions include 3 transactions with a dependency relationship, denoted as transaction 1, transaction 2, and transaction 3, respectively, where transaction 1 has a priority greater than that of transaction 2, transaction 2 has a priority greater than that of transaction 3, and so on.

Step S104, if the to-be-processed transaction is a delay transaction or a periodic cycle transaction according to the transaction information, determining a target transaction queue for storing the transaction information in a plurality of preset transaction queues, and storing the transaction information in the target transaction queue;

specifically, transaction type information is obtained from transaction information, and if the obtained transaction type information characterizes delayed processing of the transaction to be processed, the transaction to be processed is determined to be delayed transaction; if the obtained transaction type information represents that the transaction to be processed is periodically and circularly processed, determining that the transaction to be processed is periodically and circularly processed; and if the obtained transaction type information represents that the transaction to be processed is processed in real time, determining that the transaction to be processed is the real-time transaction. As an example, the identification information of each transaction type may be preset, for example, the transaction identification of the delayed transaction is 01, and accordingly, when the blockchain node obtains the transaction type information 01 from the transaction information, it is determined that the delayed transaction is performed on the transaction to be processed, that is, the transaction to be processed is the delayed transaction. As another example, the transaction type information includes transaction execution condition information, and the transaction type is determined according to the transaction execution condition information, and if the transaction type information acquired from the transaction information includes "time/24 hours", it may be determined that the periodic cycle processing is performed on the transaction to be processed, that is, the transaction to be processed is the periodic cycle transaction, or the like. It should be noted that the specific content, format, etc. of the transaction type information may be set as required in practical application.

Furthermore, in order to realize the processing of the delayed transaction and the periodic cycle transaction and the effective processing of a plurality of transactions with a dependency relationship, a plurality of transaction queues are preset in each blockchain node, each transaction queue corresponds to a priority, and the transaction information of the delayed transaction and the periodic cycle transaction is stored through the transaction queues. The number of the transaction queues can be set according to the needs in practical application, for example, 6 transaction queues are set, and the corresponding priorities are priority 1, priority 2, priority 3 …, priority 6 and the like.

Step S106, if the preset transaction packaging conditions are determined to be met, detecting target transaction information meeting the transaction processing conditions in the transaction queue based on the first intelligent contract;

the transaction packing conditions can be set according to the needs in practical application, such as the number of transactions to be packed reaches a preset number, the size of a storage space required for storing the transactions to be packed reaches a preset size, and the like.

Step S108, carrying out transaction processing according to the target transaction information, and carrying out transaction packaging processing according to the first processing result information of the transaction processing to obtain corresponding blocks of the block chain.

In one or more embodiments of the present application, when a block link point receives a transaction request sent by a first user, if it is determined that a transaction to be processed is a delayed transaction or a periodic cycle transaction according to transaction information in the transaction request, determining a target transaction queue for storing the transaction information in a plurality of preset transaction queues, and storing the transaction information in the determined target transaction queue; if the preset transaction packaging conditions are met, detecting target transaction information meeting the transaction processing conditions in each transaction queue based on the first intelligent contract; and carrying out transaction processing according to the target transaction information, and carrying out transaction packaging processing according to the first processing result information of the transaction processing to obtain a corresponding block. Therefore, through presetting a plurality of transaction queues and storing transaction information of delayed transaction or periodic cycle transaction through the transaction queues, target transaction information meeting transaction processing conditions in the transaction queues can be detected when the preset transaction packaging conditions are confirmed to be met, and transaction processing and packaging processing are carried out according to the target transaction information; the method realizes the related processing of the delay transaction and the periodic circulation transaction, enriches the transaction types and the processing modes of the transaction in the blockchain, and can meet the diversified transaction processing requirements of the current user.

To ensure that the transaction is effectively performed, in one or more embodiments of the present application, the transaction information is also validated after the transaction request is received. Specifically, as shown in fig. 3, step S104 may include the following steps S104-2:

step S104-2, if the transaction information is determined to be valid and the transaction to be processed is a delayed transaction or a periodic cycle transaction, determining a target transaction queue for storing the transaction information in a plurality of preset transaction queues, and storing the transaction information in the target transaction queue.

Wherein determining that the transaction information is valid comprises: and calling the first intelligent contract, and if the contract identification information is determined to be valid based on the first intelligent contract, signature data is verified to pass, and the storage capacity required for storing the transaction information is determined to be not more than the preset capacity, determining that the transaction information is valid.

Specifically, in order to realize effective management and call of the second intelligent contract, an association relation between contract address information and contract identification information is preset, and the association relation is stored in each blockchain node; when the service provider performs processing such as updating on the second intelligent contract, the corresponding contract address information and the updated contract identification information of the second intelligent contract are required to be sent to each blockchain node, and each blockchain node updates the stored association relation according to the received contract address information and contract identification information. When the block link point receives a transaction request, calling a first intelligent contract, and acquiring associated contract identification information from a stored association relation based on contract address information in transaction information included in the transaction request by the first intelligent contract; matching the acquired contract identification information with contract identification information in the transaction information, if the matching fails, determining that the transaction information is invalid, and sending request failure information to a first user; if the matching is successful, a corresponding public key is acquired according to the user information in the transaction information, signature data in the transaction information is verified according to the acquired public key, if verification fails, the transaction information is determined to be invalid, and request failure information is sent to the first user; if the verification is successful, determining the storage capacity required for storing the transaction information, and if the determined storage capacity is larger than the preset capacity, determining that the transaction information is invalid, and sending request failure information to the first user; and if the determined storage capacity is not greater than the preset capacity, determining that the transaction information is valid. It should be noted that, when the transaction to be processed includes a plurality of first transactions having an association relationship, the storage capacity required for storing the transaction information of each first transaction is determined respectively, and the storage capacity is determined, and when it is determined that the storage capacity required for storing the transaction information of any one of the first transactions is greater than the preset capacity, it is determined that the transaction information is invalid, and the request failure information is sent to the first user. The preset capacity may be a maximum storage capacity of the transaction queue, or a capacity value set to not exceed the maximum storage capacity of the transaction queue, for example, the maximum storage capacity of the transaction queue is 2G, the preset capacity is 1.9G, etc.

Therefore, by verifying contract identification information in the transaction information, the problems that the corresponding second intelligent contract is updated and the transaction cannot be executed are avoided; by verifying the signature data, the risk that other people impersonate the first user to initiate a transaction and cause loss to the first user is avoided; by verifying the storage capacity, the problems that the transaction cannot be effectively executed due to overlarge transaction information and incapability of being stored in a transaction queue are avoided.

Further, considering that when the transaction to be processed includes a plurality of first transactions having a dependency relationship, the execution of each first transaction needs to be performed according to a priority specified by the user, in order to ensure the sequentiality of the transaction execution, as shown in fig. 4, step S104 may include the following steps S104-4 to S104-8:

step S104-4, if the to-be-processed transaction is determined to be a delay transaction or a periodic cycle transaction according to the transaction information, determining whether the to-be-processed transaction comprises a plurality of first transactions with dependency relationships according to the transaction information, if yes, executing step S104-6, otherwise, executing step S104-8;

step S104-6, acquiring priority information among the first transactions from the transaction information, carrying out matching processing on the acquired priority information and priority information corresponding to a plurality of transaction queues to obtain target transaction queues for storing the transaction information of each first transaction, and storing the transaction information of each first transaction into the corresponding target transaction queues;

Specifically, when the first number of the first transactions is smaller than the second number of the transaction queues, each first transaction may be respectively stored in a continuous first number of transaction queues, or may be respectively stored in a discontinuous first number of transaction queues. As an example, there are 6 transaction queues, which are respectively marked as a transaction queue 1, a transaction queue 2 … and a transaction queue 6 according to the priority from high to low; the transaction to be processed comprises 3 first transactions with a dependency relationship, which are respectively marked as transaction 1, transaction 2 and transaction 3; the priority information obtained from the transaction information is that the transaction 1 is priority 1, the transaction 2 is priority 2, and the transaction 3 is priority 3; wherein, priority 1> priority 2> priority 3; the acquired priority information and the priority information of the transaction queue are matched, so that the transaction queue 1 is a target transaction queue for storing transaction information of the transaction 1, the transaction queue 2 is a target transaction queue for storing transaction information of the transaction 2, and the transaction queue 3 is a target transaction queue for storing transaction information of the transaction 3; alternatively, it is determined that the transaction queue 2 is a target transaction queue for holding transaction information of the transaction 1, the transaction queue 3 is a target transaction queue for holding transaction information of the transaction 2, and the transaction queue 4 is a target transaction queue for holding transaction information of the transaction 3; alternatively, it is determined that the transaction queue 1 is a target transaction queue for holding transaction information of the transaction 1, the transaction queue 3 is a target transaction queue for holding transaction information of the transaction 2, the transaction queue 6 is a target transaction queue for holding transaction information of the transaction 3, and the like. When the first number of the first transactions is smaller than the second number of the transaction queues, the determination mode of the target transaction queues can be set according to the needs in practical application.

Further, when the first number of the first transactions is equal to the second number of the transaction queues, each transaction queue may be determined as a target transaction queue for storing transaction information of the corresponding first transaction according to the order of priority from high to low; if the priority is from high to low transaction 1 to transaction 6, it is determined that transaction queue 1 is a target transaction queue for holding transaction information of transaction 1, transaction queue 2 is a target transaction queue … for holding transaction information of transaction 2, and transaction queue 6 is a target transaction queue for holding transaction information of transaction 6.

Further, if the first number of the first transactions is greater than the second number of the transaction queues, the transaction information may further include transaction execution information that characterizes whether the transactions may be executed concurrently. Alternatively, if the user specifies that the transactions may be executed concurrently, the first transactions may be packaged into different blocks in a priority order from high to low. Accordingly, step S104-6 may include: acquiring priority information among the first transactions from the transaction information, and dividing the first transactions into a plurality of first transaction sets according to the order of the priority from high to low if the first number of the first transactions is larger than the second number of the transaction queues and the transaction information comprises transaction execution information which characterizes the smooth execution; wherein the number of first transactions in each first transaction set is no greater than the second number; before the transaction packaging processing, determining a first transaction set to be processed currently according to the order of the priority from high to low; and matching the priority information of each first transaction in the first transaction set to be processed currently with the priority information corresponding to the transaction queues to obtain a target transaction queue for storing the transaction information of each first transaction in the first transaction set to be processed currently.

Specifically, the first transaction is divided into a plurality of first transaction sets according to the order of priority from high to low; determining a first transaction set as a first transaction set to be processed currently, and storing other first transaction sets into a transaction pool; matching the priority information of each first transaction in the current to-be-processed first transaction set with the priority information corresponding to the transaction queue to obtain a target transaction queue for storing the transaction information of each first transaction in the current to-be-processed first transaction set, and storing the transaction information of each first transaction in the current to-be-processed first transaction set into the corresponding target transaction queue; if the preset transaction packaging condition is met and the transaction information of each first transaction in the first transaction set to be processed currently is determined to be the target transaction information based on the first intelligent contract, carrying out transaction processing, and carrying out transaction packaging processing according to the first processing result information of the transaction processing to obtain a corresponding block of the block chain; acquiring a first transaction set from a transaction pool according to the order of the priority from high to low, determining the first transaction set as a first transaction set to be processed currently, and performing related processing on the first transaction set to be processed currently according to the mode to obtain a corresponding block; and so on until all processing of each first transaction set is complete. As an example, 6 transaction queues are preset, the current block height is 1000, the transaction to be processed includes 8 first transactions with a dependency relationship, and the transactions 1 and 2 and … are marked as transaction 8 in sequence from high to low according to the priority, the transactions 1 to 6 can be divided into a first transaction set, the transaction 7 and the transaction 8 are divided into a first transaction set, and the first transaction set including the transactions 1 to 6 is firstly processed to obtain a 1001 st block; the first set of transactions, including transaction 7 and transaction 8, is then processed as described above, resulting in a 1002 th block. It should be noted that, the transactions 1 to 5 may be further divided into a first transaction set, and the transactions 6 to 8 may be divided into a first transaction set, where a specific division manner of the first transaction set may be set according to needs in practical applications.

Further, if the first number of the first transactions is greater than the second number of the transaction queues, and the user specifies that the transactions cannot be executed in a smooth manner, the step S104-6 may include: acquiring priority information among the first transactions from the transaction information, and dividing each first transaction into a plurality of second transaction sets according to the order of priority from high to low if the first number of the first transactions is larger than the second number of the transaction queues and the transaction information does not comprise transaction execution information representing the smooth execution; wherein the number of the second set of transactions is no greater than the second number; determining priority information of each second transaction set, and carrying out matching processing on the determined priority information and priority information corresponding to a plurality of transaction queues to obtain a target transaction queue for storing transaction information corresponding to each second transaction set;

correspondingly, storing the transaction information in the target transaction queue may include: and storing the transaction information of each first transaction in each second transaction set into a corresponding target transaction queue in sequence from high priority to low priority.

As an example, 6 transaction queues are preset, the transaction to be processed includes 8 first transactions with a dependency relationship, and the first transactions are marked as transaction 1 and transaction 2 … transaction 8 in turn according to the priority from high to low, and then the transactions 1 to 5 can be respectively divided into a second transaction set, and the transactions 6 to 8 are divided into a second transaction set, so as to obtain 6 second transaction sets; and determining the transaction queue 1 as a target transaction queue for storing transaction information of the transaction 1, and storing the transaction information of the transaction 1 into the transaction queue 1; determining the transaction queue 2 as a target transaction queue for storing transaction information of the transaction 2, and storing the transaction information of the transaction 2 into the transaction queue 2; determining the transaction queue 3 as a target transaction queue for storing transaction information of the transaction 3, and storing the transaction information of the transaction 3 into the transaction queue 3; determining the transaction queue 4 as a target transaction queue for storing transaction information of the transaction 4, and storing the transaction information of the transaction 4 into the transaction queue 4; determining the transaction queue 5 as a target transaction queue for storing transaction information of the transaction 5, and storing the transaction information of the transaction 5 into the transaction queue 5; the transaction queue 6 is determined as a target transaction queue for storing transaction information of the transactions 6 to 8, the transaction information of the transactions 6 to 8 is sequentially stored in the transaction queue 6 from high to low in priority, the transaction 6 is executed before the transaction 7, and the transaction 7 is executed before the transaction 8. Or dividing the transaction 1 and the transaction 2 into a second transaction set, dividing the transaction 3 and the transaction 5 into a second transaction set, and dividing the transactions 6 to 8 into a second transaction set respectively to obtain 5 second transaction sets; determining a transaction queue 1 as a target transaction queue for storing transaction information of the transaction 1 and the transaction 2, and sequentially storing the transaction information of the transaction 1 and the transaction information of the transaction 2 into the transaction queue 1 according to the order of priority from high to low so that the transaction 1 is executed before the transaction 2; determining a transaction queue 2 as a target transaction queue for storing transaction information of transactions 3 to 5, sequentially storing the transaction information of the transactions 3 to 5 into the transaction queue 2 according to the order of priority from high to low, so that the transactions 3 are executed before the transactions 4, and the transactions 4 are self-propelled before the transactions 5; determining the transaction queue 3 as a target transaction queue for storing transaction information of the transaction 6, and storing the transaction information of the transaction 6 into the transaction queue 3; determining the transaction queue 4 as a target transaction queue for storing transaction information of the transaction 7, and saving the transaction information of the transaction 7 into the transaction queue 4; the transaction queue 5 is determined as a target transaction queue for storing transaction information of the transaction 8, and the transaction information of the transaction 8 is saved in the transaction queue 5. It should be noted that, the dividing manner of the second transaction set may be set according to the needs in practical application, so long as the number of the transaction sets is ensured not to be greater than the second number of the transaction queues, and each transaction in the same set is sequentially saved to the corresponding transaction queue according to the mode of priority from high to low, so as to ensure that the transaction with high priority is executed first.

Step S104-8, determining a target transaction queue for storing transaction information in a plurality of preset transaction queues according to a preset mode, and storing the transaction information to the corresponding target transaction queue.

Optionally, a transaction queue with the highest priority in the preset transaction queues is determined as a target transaction queue; or randomly selecting one transaction queue from a plurality of preset transaction queues to determine the transaction queue as a target transaction queue; and acquiring a transaction queue with the largest remaining storage capacity among a plurality of preset transaction queues, and determining the transaction queue as a target transaction queue. When the transaction to be processed does not include a plurality of first transactions with dependency relationships, the determination mode of the target transaction queue can be set according to the needs in actual application.

Therefore, through presetting a plurality of transaction queues and storing transaction information of delayed transaction or periodic cycle transaction through the transaction queues, target transaction information meeting transaction processing conditions in the transaction queues can be detected when the preset transaction packaging conditions are confirmed to be met, and transaction processing and packaging processing are carried out according to the target transaction information; the method realizes the related processing of the delay transaction and the periodic circulation transaction, enriches the transaction types and the processing modes of the transaction in the blockchain, and can meet the diversified transaction processing requirements of the current user.

It should be noted that, the total storage capacity of the transaction queue in the embodiment of the present application is smaller than the storage capacity of each block in the blockchain, and based on the consensus mechanism of the blockchain, the consistency of the transaction queue maintained by each blockchain node can be ensured, so when the transaction packaging condition is determined to be met, the transaction queue is detected, the target transaction information meeting the transaction processing condition can be ensured to be executed and packaged to the corresponding block, and the transaction processing requirements of the delayed transaction and the periodic cycle transaction are met.

In order to ensure that the plurality of first transactions having the dependency relationship are executed in the order of the specified priority, in one or more embodiments of the present application, as shown in fig. 5, step S106 includes the following steps S106-2 and S106-4:

Based on this, in one or more embodiments of the present application, when the transaction to be processed is a periodic recurring transaction, the method may further include:

And if the to-be-processed transaction meets the preset transaction removal condition, removing the transaction information from the corresponding transaction queue, and sending a transaction removal prompt message to the first user.
