Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of a block chain-based transaction processing method according to an embodiment of the present disclosure, which is suitable for adjusting UTXO precision. The method may be performed by a blockchain-based transaction processing apparatus, which may be implemented in software and/or hardware, and may be integrated into an electronic device that carries service access to blockchain-based transaction processing functions. As shown in fig. 1, the transaction processing method based on a block chain according to this embodiment may include:
s101, in response to a transfer transaction request initiated by a target user node, determining an amount of an available UTXO in a target user account, and determining actual accuracy of the amount of the available UTXO;
s102, under the condition that the actual precision is inconsistent with the expected precision, adjusting the available UTXO amount based on the actual precision and the expected precision to obtain a new UTXO amount under the expected precision;
and S103, performing digital asset transfer processing according to the new UTXO amount and the transfer transaction request.
Wherein the transfer transaction request is generated by the target user node and sent to the blockchain network. Wherein the target user node may initiate a transfer transaction request to the blockchain network. The target user node may or may not be a blockchain link point in a blockchain network. Whether the target user node is a block link point is determined according to actual conditions, and is not limited herein.
Optionally, the transfer transaction request includes a target user account. Wherein the target user account belongs to the target user node. The transfer transaction request is used for requesting block chain link points in the block chain network to transfer the available UTXO of the target user account.
Wherein the available UTXO includes an amount of the available UTXO and an actual accuracy of the amount of the available UTXO. The actual accuracy of the available UTXO amount and the available UTXO amount are recorded in a block of the blockchain network, which may be obtained by blockchain link points.
It will be appreciated that the amount of UTXO available is the amount of UTXO in the target user account with actual accuracy. The actual accuracy refers to the UTXO accuracy in the blockchain network that is being validated, i.e., the smallest cutting unit that is being validated. In general, the UTXO accuracy specifies the number of bits after the decimal point of the UTXO holding amount, and for example, when the UTXO accuracy is 2, the UTXO holding amount can be expressed as 100.00. For example, when the UTXO accuracy is 3, the UTXO holding amount is 100.000.
And the block link point acquires a transfer transaction request initiated by the target user node, and determines a target user account according to the transfer transaction request. The blockchain node determines the amount of available UTXO in the target user account and determines the actual accuracy of the amount of available UTXO.
The block link points determine whether the actual accuracy is consistent with the desired accuracy. The desired accuracy refers to the UTXO accuracy desired to be effective. As the transaction service develops, the actual accuracy may no longer adapt to the transaction service, and in such a case, the actual accuracy generally needs to be adjusted, and optionally, the actual accuracy is adjusted to the desired accuracy.
The block link points determine whether the actual accuracy is consistent with the desired accuracy, in effect whether the desired accuracy has been validated against the target user account. In other words, it is determined whether the UTXO accuracy of the target user account has been adjusted to the desired accuracy. The expected accuracy may or may not coincide with the actual accuracy, and whether the expected accuracy coincides with the actual accuracy is determined according to the actual situation, and is not limited herein.
If the actual accuracy is inconsistent with the expected accuracy, indicating that the expected accuracy does not take effect on the amount of the UTXO available in the target user account; if the actual accuracy is consistent with the desired accuracy, it is indicated that the desired accuracy has been validated against the amount of UTXO available in the target user account, which has corresponded to the desired accuracy.
In the event that the actual accuracy does not match the desired accuracy, the block link points need to be adjusted for UTXO accuracy for the target user account. Optionally, the block link point adjusts the UTXO accuracy of the target user account to the desired accuracy. Under the condition that the actual precision is consistent with the expected precision, the block chain node does not need to adjust the UTXO precision of the target user account
It will be appreciated that the amount of UTXO held in the target user account is determined by the amount of UTXO available in the target user account and the actual accuracy of the amount of UTXO available. In order to ensure the user experience, the UTXO holding amount of the target user account needs to be kept unchanged during the process of adjusting the UTXO accuracy of the target user account. The UTXO holding amount of the target user account determined by the available UTXO amount and the actual accuracy of the available UTXO amount is called a first UTXO holding amount; the new UTXO amount at the desired accuracy and the UTXO holding amount of the target user account determined by the desired accuracy are referred to as a second UTXO holding amount. The UTXO holding amount of the target user account is kept unchanged, that is, it is necessary to ensure that the first UTXO holding amount is equal to the second UTXO holding amount.
The block link points adjust the amount of available UTXO based on the actual accuracy and the desired accuracy to obtain a new amount of UTXO at the desired accuracy. The relative magnitude relationship between the new amount of UTXO and the amount of UTXO available is related to the relative magnitude relationship between the actual accuracy and the desired accuracy. Under the condition that the holding amount of the UTXO is not changed, the smaller the minimum division unit of the UTXO is, the larger the amount of the divided UTXO is.
After the block link point adjusts the UTXO accuracy for the target user account to the desired accuracy, a new UTXO amount at the desired accuracy may be determined. And the block chain node performs digital asset transfer processing according to the new UTXO amount and the transfer transaction request. Wherein the digital asset is a non-monetary asset owned or controlled by a target user account in the form of electronic data.
It is noted that the block chain node only adjusts the UTXO accuracy of the target user account if the transfer transaction request is initiated by the target user node and the actual accuracy of the available UTXO amount in the target user account is inconsistent with the desired accuracy, i.e., the UTXO accuracy adjustment in the embodiments of the present disclosure is performed during the processing of the transfer transaction request.
And the UTXO precision in the target user account corresponding to the request for initiating the transfer transaction is only adjusted, but not the UTXO precision of all the user accounts in the block chain network. The UTXO precision is used as a system parameter of the block chain network, the UTXO precision of all user accounts in the block chain network is adjusted, the data processing pressure of the block chain network is huge, and network congestion can be caused. The UTXO precision in the target user account corresponding to the transfer transaction initiating request is only adjusted, so that the UTXO precision adjusting pressure can be dispersed, network congestion is avoided, and the influence on business service is reduced.
The amount of the UTXO available in the target user account is determined, and the actual precision of the amount of the UTXO available is determined; under the condition that the actual precision is inconsistent with the expected precision, adjusting the amount of the available UTXO based on the actual precision and the expected precision to obtain a new UTXO amount under the expected precision; and performing digital asset transfer processing according to the new UTXO amount and the transfer transaction request. Under the condition that the holding quantity of the UTXO of the target user account is not influenced, the UTXO precision can be adjusted, and the user experience is guaranteed. In the transfer transaction request processing process, the UTXO precision of the target user account is adjusted, the data processing pressure of a block chain network is dispersed, network congestion is avoided, the influence on service is reduced, and user experience is further guaranteed.
In an alternative embodiment, performing digital asset transfer processing based on the new UTXO amount and the transfer transaction request comprises: determining the amount of the UTXO required under the expected precision according to the transfer transaction request; determining the amount of the residual UTXO according to the amount of the required UTXO and the new UTXO amount; transferring the required UTXO amount from the target user account and returning the remaining UTXO amount to the target user account.
Wherein the required amount of the UTXO refers to the amount of the UTXO required to be transferred from the target user account. The amount of UTXO required corresponds to the desired accuracy. The new UTXO amount refers to the total UTXO amount in the target user account at the desired accuracy.
It will be appreciated that the transfer transaction for the UTXO consists of a transaction output and a transaction input, and in particular that the new UTXO amount at the desired accuracy is divided into the required UTXO amount and the remaining UTXO amount. Wherein, the required UTXO amount is used as transaction output and is transferred out from the target user account; the remaining amount of the UTXO is returned to the target user account as a transaction input.
Optionally, the transfer transaction request further includes: the amount of UTXO needed at the desired accuracy.
The block chain node determines the amount of UTXO required at the desired accuracy based on the transfer transaction request. Optionally, the block chain node determines whether the new UTXO amount is greater than or equal to the required UTXO amount, and if the new UTXO amount is greater than or equal to the required UTXO amount, the block chain node determines the remaining UTXO amount according to the required UTXO amount and the new UTXO amount, indicating that the new UTXO amount in the target user account is sufficient to support the transfer transaction. The block link transfers the desired UTXO amount from the target user account and transfers the remaining UTXO amount to the target user account.
And if the new UTXO amount is smaller than the required UTXO amount, the new UTXO amount in the target user account is not enough to support the transfer transaction, the block chain node generates transfer transaction failure information, and the transfer transaction failure information is fed back to the target user node.
According to the technical scheme, the UTXO transfer transaction with the expected precision is realized based on the new UTXO amount and the transfer transaction request with the expected precision, the influence on the service is reduced, and meanwhile, the accuracy of the transfer transaction is ensured.
Fig. 2 is a flowchart of another transaction processing method based on a block chain according to an embodiment of the present disclosure; the present embodiment is an alternative proposed on the basis of the above-described embodiments. Specifically, the disclosed embodiments refine the operation "determining the amount of available UTXO in the target user account, and determining the actual accuracy of the amount of available UTXO".
Referring to fig. 2, the transaction processing method based on a block chain provided in this embodiment includes:
and S201, responding to a transfer transaction request initiated by a target user node, and determining the reference block height of a block to which the available UTXO amount belongs.
It is known that the amount of available UTXO is stored in different tiles scattered across the blockchain network. Different blocks are distinguished by block height.
The reference tile height refers to the tile height of the tile to which the amount of UTXO available for the target user account belongs. Wherein the block height may be determined according to the block generation time. The reference block height is used to determine the actual accuracy of the amount of UTXO available.
The block chain node determines a reference block height for the block to which the available UTXO amount belongs in response to a transfer transaction request initiated by the target user node.
And S202, determining the actual precision of the amount of the available UTXO according to the reference block height based on the correlation between the preset block height and the actual precision.
The association relationship between the preset block height and the actual precision is predetermined according to the actual situation. And the preset incidence relation between the block height and the actual precision is used for recording the corresponding relation between the block height and the actual precision.
Optionally, the preset association relationship between the block height and the actual precision is a pair (pair) formed by the block height and the actual precision. I.e. the block height and the actual precision are combined into a set of data.
And the block chain node determines the actual precision of the amount of the available UTXO according to the reference block height based on the association relationship between the preset block height and the actual precision.
And S203, when the actual precision is inconsistent with the expected precision, adjusting the amount of the available UTXO based on the actual precision and the expected precision to obtain a new UTXO amount under the expected precision.
And S204, performing digital asset transfer processing according to the new UTXO amount and the transfer transaction request.
In the embodiment of the disclosure, the reference block height of the block to which the amount of the available UTXO belongs is determined through the block chain node, the actual accuracy of the amount of the available UTXO is determined according to the reference block height based on the association relationship between the preset block height and the actual accuracy, and the actual accuracy is used for determining a new amount of the UTXO with an expected accuracy, so that data support is provided for adjusting the UTXO accuracy of the target user account. According to the embodiment of the disclosure, by setting the association relationship between the preset block height and the actual precision, the block chain link point can determine the actual precision of the usable UTXO amount according to the reference block height, and the UTXO precision can be adjusted without damaging the original data structure of the block chain.
In an optional embodiment, the method further comprises: responding to a voting proposal transaction for adjusting UTXO precision in the block chain network, and acquiring a voting result; if the voting result is that the voting passes, extracting the expected precision from the voting proposal transaction; writing the extracted expected precision into a block chain network, and taking the block height to which the expected precision belongs as the block height associated with the expected precision.
Since the UTXO accuracy is a system parameter of the blockchain network, adjusting the UTXO accuracy requires initiating a voting proposal transaction in the blockchain network to adjust the UTXO accuracy. The voting proposal transaction is used for controlling whether the UTXO precision is adjusted or not to vote by the block chain link point pairs in the block chain network.
And responding to the voting proposal affair for adjusting the UTXO precision in the block chain network by the block chain link point to acquire a voting result. Optionally, the voting proposal transaction includes a voting effectiveness ratio threshold. And the voting result is determined according to the passing ticket proportion value and the voting effective proportion threshold value. Specifically, if the passing vote ratio value is greater than or equal to the voting effective ratio threshold value, determining that the voting result is voting passing; and if the passing vote ratio value is smaller than the voting effective ratio threshold value, determining that the voting result is that the voting does not pass.
The passing ticket proportion value is the proportion of the number of passing tickets to the total number of tickets. The vote validation ratio threshold is used to determine whether the vote proposal transaction can be validated. The UTXO accuracy may be adjusted only if the voting proposal transaction can take effect. The voting effective proportion threshold is determined according to actual service requirements, and is not limited herein. Illustratively, the vote validation proportion threshold may be 50%.
Optionally, the voting proposal transaction also includes a desired accuracy. And under the condition that the voting result is that the voting passes, extracting the expected precision from the voting proposal transaction by the blockchain node, and writing the extracted expected precision into the blockchain network. The extracted expected accuracy is written into the block chain network, namely, the expected accuracy is subjected to uplink storage, and the expected accuracy is written into the block. The block link points use the block height to which the desired accuracy belongs as the block height to which the desired accuracy is associated.
It will be appreciated that the desired accuracy and the actual accuracy are relative, and in general, after writing the desired accuracy to the blockchain network, the desired accuracy becomes effective as the actual accuracy. The expected accuracy and the block height to which the expected accuracy belongs can be used for determining the association relationship between the preset block height and the actual accuracy.
According to the technical scheme, the voting proposal transaction for adjusting the UTXO precision is initiated to the block chain network, the block chain link points in the block chain network are controlled to vote for the voting proposal transaction, and the expected precision in the voting proposal transaction is written into the block chain network under the condition that the voting result is that the vote passes, so that the traceability of the UTXO precision is ensured, and data support is provided for adjusting the UTXO precision in the process of processing the transfer transaction request.
In an optional embodiment, the method further comprises: determining an available UTXO amount in a target user account in response to a query transaction request initiated by a target user node; determining a reference block height of a block to which the available UTXO amount belongs, and determining actual accuracy of the available UTXO amount based on a correlation between the block height and the actual accuracy; in the event that the actual accuracy does not correspond to a desired accuracy, a new UTXO amount at the desired accuracy is determined based on the desired accuracy, the actual accuracy, and the available UTXO amount.
Wherein the query transaction request is generated by the target user node and sent to the blockchain network. The query transaction request is used for requesting the block chain link points in the block chain network to perform query processing on the available UTXO of the target user account.
As described above, the available UTXO includes the amount of the available UTXO and the actual accuracy of the amount of the available UTXO. The amount of UTXO that can be held is determined by the actual accuracy of the amount of UTXO available and the amount of UTXO available. Different actual precisions correspond to different amounts of UTXO available, with the amount of UTXO held remaining unchanged.
The block chain node determines the amount of available UTXO in the target user account in response to a query transaction request initiated by the target user node. It is known that the UTXO amount is only relevant if it correlates to UTXO accuracy. It is not of reference significance to consider only the UTXO amount regardless of UTXO accuracy. After determining the amount of UTXO available, the blockchain node needs to further determine the actual accuracy of the amount of UTXO available.
Specifically, the block link point determines a reference block height of a block to which the usable UTXO amount belongs, and determines the actual accuracy of the usable UTXO amount based on a correlation between the block height and the actual accuracy. In the event that the actual accuracy does not coincide with the desired accuracy, the block link point determines a new amount of UTXO at the desired accuracy based on the desired accuracy, the actual accuracy, and the amount of UTXO available.
Optionally, the block node feeds back the new UTXO amount with the desired accuracy to the target user node as a request processing result of the query transaction request.
It should be noted that in the embodiment of the present disclosure, the block chain node does not adjust the UTXO precision in the target user account during the process of processing the query transaction request, because the query transaction request is not written into the block chain network, and the block chain node only scales the UTXO precision during the process of processing the query transaction request to determine a new UTXO amount with a desired precision. And feeding back the new UTXO amount under the expected precision as a request processing result to the target user node.
According to the technical scheme, the target user node is supported to query a new UTXO amount in the target user account at a desired precision based on the query transaction request, the UTXO amount query accuracy is improved, a user can conveniently master the latest UTXO amount at different UTXO precisions in time, and the user experience is improved.

Specifically, the embodiment of the present disclosure refines the operation "when the actual accuracy is inconsistent with the desired accuracy, adjust the available UTXO amount based on the actual accuracy and the desired accuracy to obtain a new UTXO amount at the desired accuracy".

S302, determining the new UTXO amount based on the actual accuracy, the desired accuracy and the available UTXO amount.
It can be understood that, in order to ensure the user experience, the UTXO holding amount of the target user account needs to be kept unchanged during the process of adjusting the UTXO accuracy of the target user account. Different UTXO accuracies correspond to different UTXO amounts, with the UTXO hold amount remaining unchanged.
Wherein the amount of UTXO available corresponds to the actual accuracy. The new amount of UTXO corresponds to the desired accuracy.
The UTXO hold amount may be determined based on the actual accuracy and the amount of UTXO available at the actual accuracy. With the amount of UTXO hold and desired accuracy known, a new amount of UTXO at the desired accuracy may be determined.
S303, using the expected accuracy as the UTXO accuracy of the new UTXO amount.
As mentioned above, the UTXO amount has reference only in relation to UTXO accuracy. It is not of reference significance to consider only the UTXO amount regardless of UTXO accuracy. The block link point will use the desired accuracy as the UTXO accuracy for the new UTXO amount.
And S304, performing digital asset transfer processing according to the new UTXO amount and the transfer transaction request.

In an alternative embodiment, determining the new UTXO amount based on the actual accuracy, the desired accuracy, and the available UTXO amount comprises: determining a precision difference between the desired precision and the actual precision; and determining the new UTXO amount according to the precision difference value and the available UTXO amount.
Wherein the accuracy difference is determined according to the desired accuracy and the actual accuracy. The accuracy difference may reflect the accuracy change in the UTXO accuracy. The accuracy difference is used to determine a new UTXO amount at the desired accuracy.
The blockchain node determines a precision difference between the desired precision and the actual precision. A new amount of UTXO at the desired accuracy is determined based on the accuracy difference and the amount of available UTXO. According to the technical scheme, the new UTXO amount under the expected precision is determined based on the actual precision, the expected precision and the available UTXO amount under the actual precision, and the new UTXO amount under the expected precision is used for UTXO transfer transaction, so that the transfer transaction accuracy is guaranteed.
In an alternative embodiment, determining the new amount of UTXO based on the accuracy difference and the available amount of UTXO comprises: determining the new UTXO amount based on the accuracy difference and the available UTXO amount based on the following equation: u shape 2 =U 1

The embodiment of the disclosure is applicable to the case of adjusting the UTXO precision.
