Technical Field
The present application relates to the field of information technologies, and in particular, to a transaction fee payment method, device and storage medium based on parallel execution.
Background
Nodes in the blockchain transfer and store data by sending transactions, and accounting nodes in the blockchain collect transactions in the blockchain in a transaction pool and then execute the transactions, and after executing the transactions, package the transactions into blocks and spread the transactions into the blockchain. In the prior public chain system, in order to prevent a malicious user from attacking, a certain transaction fee needs to be charged, so that the block chain system can be effectively prevented from being attacked by a huge amount of defenses, however, when the transaction is executed in parallel, payment of the transaction fee needs to be redesigned, and erroneous execution of the transaction caused by the parallel execution, such as time consumption caused by insufficient account balance for paying the transaction, is prevented, and the transaction which cannot be packaged originally is finally executed due to the parallel execution.
In the chain33 blockchain account model and the transaction execution model, payment of transaction fees is unified in a coins contract, when the same initiator initiates a plurality of contract transactions, for example, in an agent environment, a plurality of transaction fees need to be deducted from an account of the initiator, but when the blockchain system adopts a parallel transaction mechanism to execute, the transaction execution is not executed according to the transaction sequence any more, and at this time, the original transaction fee payment mechanism may cause that the transaction cannot be executed in parallel.
In view of the foregoing, there is a need for a transaction fee payment method based on parallel execution, so that parallel acceleration execution can be performed for different types of transactions without affecting the same transaction initiator.

Detailed Description
For a further understanding of the present application, the present application will be described in detail with reference to the drawings and examples.
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that, for convenience of description, only the portions related to the application are shown in the drawings.
The first, second, etc. words are provided for convenience in describing the technical scheme of the present application, and have no specific limitation, and are all generic terms, and do not constitute limitation to the technical scheme of the present application. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
Example 1
A transaction fee payment method based on parallel execution, comprising:
analyzing all sponsors to be executed in the block to obtain a sponsor list; constructing a transaction information table for each initiator according to the initiator list, wherein the transaction information table comprises transaction information of all transactions to be executed, which are initiated by the corresponding initiator; wherein the transaction information includes Tx-index, type, previous, current and a balance; the transactions to be executed comprise a class of transactions and a class of transactions, wherein the class of transactions is coins contract transactions, and the class of transactions is other types of contract transactions except the coins transactions;
the second class of transactions are divided into a front transaction, a middle transaction and a rear transaction according to the execution sequence relation between the front transaction and the first class of transactions, wherein the front transaction is the second class of transactions with the execution sequence before all the first class of transactions, the middle transaction is the second class of transactions with the execution sequence between the two first class of transactions, and the rear transaction is the second class of transactions with the execution sequence after all the first class of transactions;
the transaction fee payment method comprises the following steps:
preamble transaction: when the preamble transaction is executed, the values of previous, current and balance of all types of transactions need to be deducted, wherein the transaction fee of the preamble transaction is used as new previous, current and balance, the new current value of all types of transactions is larger than 0, and otherwise, the preamble transaction is not packed;
centering transaction: when the centering transaction is executed, firstly, acquiring the value of the balance of a class of transaction adjacent to the centering transaction to be executed before the centering transaction to be executed as the previous of the centering transaction to be executed, and adopting the data obtained by subtracting the transaction fee from the value of the balance as the new current and the new balance of the centering transaction to be executed; then, the value of the balance after updating the centering transaction to be executed is used as the value of previous of a class of transaction adjacent to the centering transaction to be executed after the centering transaction to be executed in the transaction sequence, and the current and the balance of the class of transaction are subtracted by the transaction fee for executing the centering transaction to be used as new current and balance; wherein the current and the balance of the new class of transaction adjacent to the intermediate transaction to be executed after the intermediate transaction to be executed are both greater than 0, and the current and the balance of the new class of transaction adjacent to the intermediate transaction to be executed after the intermediate transaction to be executed are also greater than 0, otherwise, the intermediate transaction to be executed is not packaged
And (5) carrying out subsequent transaction: when the subsequent transaction is executed, the value of the balance of the class of transaction adjacent to the subsequent transaction to be executed is obtained as the previous of the subsequent transaction to be executed, and the current and the balance of the subsequent transaction to be executed are modified to be the value obtained by subtracting the transaction fee of the subsequent transaction to be executed from the balance of the class of transaction adjacent to the subsequent transaction to be executed.
Compared with the prior art, the scheme provided by the embodiment has the beneficial effects that the parallel acceleration of the transaction can be used in a more loose environment, and particularly when the transaction is sent by using the transaction sending agent mechanism, the parallel execution acceleration of the transaction can still be carried out for the same transaction initiator.
In the above technical solution, since the balance of the transaction address can be modified by the coins contract transaction itself, the transaction fee can be directly deducted when the coins contract transaction is executed according to the prior art, and the scheme is not limited, and for the non-coins contract transaction, the transaction fee needs to be settled by the coins contract, therefore, when the transaction is the preamble transaction, the existing balance of the account of all the coins transactions after the preamble transaction, that is, the current, is greater than the transaction fee of the preamble transaction, so as to ensure that the transaction fee is not lost when the preamble transaction is executed, and if the existing balance of the account of the coins transaction is less than the transaction fee, the preamble transaction is removed. When the previous of the centering transaction is the balance of the account of the last coins transaction, and the balance of the centering transaction is only the transaction fee, the current and the balance of the centering transaction are both modified to be the balance of the account of the last coins transaction minus the transaction fee of the centering transaction, while the previous of the coins transaction after the centering transaction is used along the balance of the account of the centering transaction, namely the balance of the centering transaction is adopted, and the current and the balance of the coins transaction after the centering transaction are also required to be subtracted by the balance of the centering transaction, so that the transaction fee of the centering transaction is actually settled in the address account, the balance of the account is actually modified due to the generation of the transaction fee of the centering transaction, but the balance of the account is not directly modified by the two types of transactions, so that the coins after the centering transaction is reflected in the latter coins, the coins transaction after the centering transaction is reflected, and the previous coiins transaction is not affected. For the subsequent transaction, the same is a second-class transaction, wherein only transaction fees are recorded in the coin transaction, namely only transaction fees change the balance of an account, so that the previous transaction accounts for the balance of the account with the previous coins transaction, the transaction process only deducts the transaction fees, and the current and the balance adopt the balance of the account with the previous coins transaction to subtract the transaction fees, thus the transaction fees are recorded in the account. After the method is adopted, transaction fees of all the two types of transactions are analyzed in the executor, if the balance of the account is insufficient, the two types of transactions are removed, then the situation of insufficient transaction fees is not needed to be considered when the transactions need to be executed in parallel, the method is particularly suitable for a proxy scene, when a transaction proxy exists, the account of the proxy party can become a transaction initiator many times, if the existing transaction fee payment mechanism cannot be used at all for parallel transactions, the settlement of the transaction fees can influence the parallel execution of the transactions, and the parallel execution acceleration of the transactions can be carried out for the same transaction initiator by adopting the method for settlement of the transaction fees.
In this embodiment, all transaction sponsors in the block are parsed to obtain a transaction sponsor list, as shown in fig. 1, from_0, from_1.
For example, the transaction initiator from_0 initiates 6 transactions altogether, the index of these 6 transactions is 0, 1,3, 4, 5, 15 respectively, wherein the index is 0 is a token transaction, the index is 1,3,5 is a coins contract transaction, the index is 4 is a private transaction, the index is 15 is a trade transaction, a transaction information table of from_0 is built, as shown in fig. 2, other contract transactions related to from_0 have the same account modification address as coins contract transaction, only the account balance is changed by the coins transfer transaction, including the transfer initiator and the receiver, the order of other contract transactions in the block includes 3 cases before, during and after all the coins transaction, and the specific implementation mechanism is as follows:
1. preamble transactions
As shown in FIG. 2, the token transaction has index of 0, the execution order of the transaction in the blockchain is before the coins with index of 1, so the receipt of the token transaction is not modified, and the previous and current and balance values in three coins with index of 1,3 and 5 need to be subtracted by 0 transaction fee with tx, and the current value after subtraction must be equal to or greater than 0, so the insufficient balance of the account is denied, and the transaction cannot be packed.
2. Centered transactions
The private transaction, shown in fig. 2, has index 4, the order of execution of the transactions in the blockchain follows the coins of index 3, and precedes the transactions of index 5, so,
the receipt of coins transactions 1 and 3 is not modified;
the previous of the private transaction with index 4 is replaced by a balance with replacement index 3, and both current and balance are modified to be balance-txfee;
and the version of the coren transaction with index of 5 is replaced by the price of the private transaction, and the current and price values need to be subtracted from the transaction fee of the private transaction;
and if the balance is insufficient to pay for the transaction time in the modification process, rejecting the transaction and not packaging the transaction.
3. Post-order transaction
As shown in FIG. 2 for the trade transaction, which has index 15, the order of execution of the transactions in the blockchain follows the coins with index 5, thus replacing previous with a balance with index 5, and both current and balance are modified to be balance-txfee.
It should be noted that, the preamble transaction, the intermediate transaction and the post-transaction set forth in the present solution are basic transaction mechanisms when only implementing the transaction, the preamble transaction modification in the description of the present solution is not inherited to the intermediate transaction, and other conditions are the same, but only the basic transaction mechanism is described, and when each type of second-class transaction is implemented in a specific manner, there are partial overlapping, and there are multiple forms of combination, which does not affect the implementation of the method of the present solution, and the basic transaction mechanism of each type of second-class transaction is the transaction mechanism disclosed in the present solution in any form of combination, and other technical solutions formed by any combination of the above technical features or the equivalent features thereof are all within the protection scope of the present solution.
