[0026] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0027] Figure 1 This is a flowchart illustrating a blockchain-based transaction processing method according to an embodiment of this disclosure. This disclosure is applicable to situations where UTXO precision needs adjustment. The method can be executed by a blockchain-based transaction processing device, which can be implemented in software and / or hardware and integrated into an electronic device that hosts service access to blockchain-based transaction processing functionality. Figure 1 As shown, the blockchain-based transaction processing method in this embodiment may include:

[0028] S101, in response to a voting proposal transaction that adjusts the precision of UTXOs in the blockchain network, extract the desired precision from the voting proposal transaction and determine the actual precision of the amount of UTXOs available in the blockchain network;

[0029] S102, if the actual accuracy is inconsistent with the expected accuracy, control the block nodes in the blockchain network to vote on the voting proposal transaction and obtain the voting results;

[0030] S103, if the voting result is that the vote passes, then the number of available UTXOs is adjusted according to the actual precision and the expected precision to obtain a new number of UTXOs under the expected precision.

[0031] As we know, UTXO precision refers to the smallest unit of UTXO division, and UTXO amount refers to the number of UTXOs in a block within that smallest unit of division. In simpler terms, UTXO precision specifies the number of decimal places in the UTXO holding value. For example, with a UTXO precision of 2, the UTXO holding value can be represented as 100.00. Similarly, with a UTXO precision of 3, the UTXO holding value is represented as 100.000.

[0032] The available UTXO amount refers to the number of UTXOs in the blockchain network at the actual precision. Actual precision refers to the UTXO precision currently in effect in the blockchain network, which is the smallest unit of division currently in effect. Expected precision refers to the UTXO precision expected to be in effect. As transaction business develops, the actual precision may no longer be suitable for transaction business. In this case, it is generally necessary to adjust the actual precision; alternatively, the actual precision can be adjusted to the expected precision.

[0033] It is understandable that expected precision and actual precision are relative. Generally speaking, once the expected precision is written into the blockchain network, it becomes the actual precision. The specific values ​​of actual precision and expected precision can be determined according to actual business needs. The expected precision may or may not be consistent with the actual precision. Whether the expected precision and actual precision are consistent depends on the actual situation and is not limited here.

[0034] Optionally, the voting proposal transaction includes the desired precision. In response to a voting proposal transaction that adjusts the precision of UTXOs in the blockchain network, the block node extracts the desired precision from the voting proposal transaction and determines the actual precision of the number of UTXOs available in the blockchain network.

[0035] Block nodes determine whether the actual precision matches the expected precision, thus determining whether the expected precision has taken effect in the blockchain network. If the actual precision does not match the expected precision, it indicates that the expected precision has not yet taken effect in the blockchain network; if the actual precision matches the expected precision, it indicates that the expected precision has taken effect in the blockchain network. The number of available UTXOs in the blockchain network already corresponds to the actual precision, and there is no need to adjust the UTXO precision in the blockchain network. In the case of a discrepancy between the actual precision and the expected precision, block nodes need to adjust the UTXO precision in the blockchain network. Optionally, block nodes adjust the UTXO precision in the blockchain network to the expected precision.

[0036] Since UTXO precision is a system parameter of the blockchain network, adjusting UTXO precision requires initiating a voting proposal transaction within the blockchain network. This voting proposal transaction controls the voting among block nodes in the blockchain network regarding whether to adjust the UTXO precision.

[0037] Block nodes vote on voting proposals, specifically on whether to adjust UTXO precision. Block nodes obtain the voting results for these proposals and determine whether to adjust the UTXO precision in the blockchain network based on those results.

[0038] Optionally, the voting proposal includes a voting validity threshold. The voting result is determined based on the percentage of votes passed and the voting validity threshold. Specifically, if the percentage of votes passed is greater than or equal to the voting validity threshold, the vote is considered passed; conversely, if the percentage of votes passed is less than the voting validity threshold, the vote is considered failed.

[0039] The "passing vote ratio" refers to the proportion of votes that passed out of all votes. The voting validity threshold is used to determine whether a voting proposal transaction can be effective. UTXO precision can only be adjusted if the voting proposal transaction is effective. The voting validity threshold is determined based on actual business needs and is not limited here. For example, the voting validity threshold can be 50%.

[0040] The voting results include: vote in favor and vote against. If the vote is in favor, the block node adjusts the number of available UTXOs based on the actual precision and the expected precision to obtain a new number of UTXOs at the expected precision.

[0041] It is known that the total number of UTXOs held is determined by both the amount of UTXOs and their precision. Therefore, to ensure a good user experience, the total number of UTXOs held in the blockchain network must remain constant while adjusting the precision of UTXOs.

[0042] The amount of available UTXOs and the UTXO holdings determined by the actual precision of the available UTXOs are referred to as the first UTXO holdings; the new amount of UTXOs under the desired precision and the UTXO holdings determined by the desired precision are referred to as the second UTXO holdings. Maintaining the total UTXO holdings in the blockchain network means ensuring that the first UTXO holdings are equal to the second UTXO holdings.

[0043] Block nodes adjust the available UTXO amount based on the actual precision and the expected precision to obtain a new UTXO amount at the expected precision. The relative size relationship between the new UTXO amount and the available UTXO amount is related to the relative size relationship between the actual precision and the expected precision. With the total UTXO holdings remaining constant, the smaller the minimum unit of UTXO division, the more UTXOs are obtained from the division. After the block nodes adjust the UTXO precision in the blockchain network to the expected precision, the new UTXO amount at the expected precision can be determined.

[0044] It is known that the amount of UTXOs is distributed and stored across different blocks in the blockchain network. In this embodiment of the disclosure, the block node adjusts the UTXO precision of the blockchain network by batch adjusting all UTXOs distributed across various blocks in the blockchain network.

[0045] In this embodiment, the desired precision is extracted from voting proposal transactions by block nodes, and the actual precision of the available UTXO amount in the blockchain network is determined. If the actual precision differs from the desired precision, the block nodes in the blockchain network are controlled to vote on the voting proposal transaction. If the vote passes, the available UTXO amount is adjusted based on the actual and desired precision to obtain a new UTXO amount with the desired precision. This provides technical support for adjusting the UTXO precision in the blockchain network, enabling adjustment of UTXO precision without affecting users' UTXO holdings, simplifying the UTXO precision adjustment method and reducing its difficulty. This embodiment also performs batch adjustments on all UTXOs in the blockchain network when the voting proposal transaction for adjusting UTXO precision passes, improving the efficiency of UTXO precision adjustment.

[0046] To help users understand the precision of UTXOs in the blockchain network, it is necessary to announce any adjustments to the precision of UTXOs in the blockchain network.

[0047] In an optional embodiment, the method further includes: if the voting result is that the vote passes, then invoking the announcement smart contract to generate a precision adjustment announcement; wherein the precision adjustment announcement includes at least: precision adjustment content and precision adjustment time.

[0048] The announcement smart contract is used to generate precision adjustment announcements. These announcements inform the blockchain network of the details and timing of UTXO precision adjustments. The precision adjustment details are determined based on the actual and desired precision. The precision adjustment time refers to the start time of the UTXO precision adjustment. The specific details and timing of these adjustments are determined based on actual business needs and are not limited here.

[0049] If the vote passes, the block node invokes the announcement smart contract to generate a precision adjustment announcement. This technical solution helps users understand the UTXO precision in the blockchain network, thus improving the user experience.

[0050] UTXO precision is a system parameter of the blockchain network. Adjusting the UTXO precision in the blockchain network involves adjusting the number of UTXOs in a large number of blocks, which puts enormous pressure on the blockchain network's data processing and may cause network congestion. To ensure the accuracy of transfer transactions, the blockchain network refuses to provide transfer services to external parties during the process of adjusting the UTXO precision.

[0051] In an optional embodiment, the method further includes: in response to a transfer transaction request, determining the expected transfer time of the transfer transaction request; if the expected transfer time is within the precision adjustment time, then refusing to process the transfer transaction request.

[0052] Optionally, the transfer transaction request includes the expected transfer time. The block node responds to the transfer transaction request by determining the expected transfer time. If the expected transfer time is within the precision adjustment time, the transfer transaction request is rejected. This technical solution ensures the accuracy of transfer transactions.

[0053] Figure 2 This is a flowchart of another blockchain-based transaction processing method provided according to an embodiment of this disclosure; this embodiment is an optional solution proposed based on the above embodiments. Specifically, this disclosure embodiment refines the operation "adjusting the available UTXO amount according to the actual precision and the expected precision to obtain a new UTXO amount under the expected precision".

[0054] See Figure 2 The blockchain-based transaction processing method provided in this embodiment includes:

[0055] S201, in response to a voting proposal transaction that adjusts the precision of UTXOs in the blockchain network, extract the desired precision from the voting proposal transaction and determine the actual precision of the amount of UTXOs available in the blockchain network.

[0056] S202, if the actual accuracy is inconsistent with the expected accuracy, control the block nodes in the blockchain network to vote on the voting proposal and obtain the voting results.

[0057] S203, if the voting result is that the vote passes, then the block to which the available UTXO amount belongs is determined as the target block.

[0058] UTXO amounts are distributed and stored across different blocks in the blockchain network. The target block refers to the block that stores the UTXO amounts.

[0059] If the vote passes, the block node will identify the block containing the available UTXO amount as the target block.

[0060] S204, determine the number of available UTXOs in the target block at the actual precision, and use it as the current number of UTXOs.

[0061] The block node determines the number of available UTXOs in the target block at the actual precision, and uses it as the current number of UTXOs.

[0062] S205, based on the actual accuracy, the expected accuracy, and the current UTXO amount, determine the new UTXO amount in the target block at the expected accuracy.

[0063] Understandably, to ensure a good user experience, the number of UTXOs held needs to remain constant while adjusting UTXO precision. With the number of UTXOs held constant, different UTXO precisions correspond to different numbers of UTXOs.

[0064] The available UTXO amount in the target block at the actual precision is the current UTXO amount, which corresponds to the actual precision. The new UTXO amount corresponds to the expected precision.

[0065] The amount of UTXOs held in the target block can be determined based on the actual precision and the current number of UTXOs. Given the amount of UTXOs held and the desired precision, the new number of UTXOs in the target block at the desired precision can be determined.

[0066] In this embodiment of the disclosure, the blockchain node determines the new UTXO amount in the target block at the desired precision based on the actual precision, the desired precision, and the current UTXO amount, providing data support for adjusting the UTXO precision in the blockchain network.

[0067] In an optional embodiment, determining a new UTXO number in the target block at the desired precision based on the actual precision, the desired precision, and the current UTXO number includes: determining a precision difference between the actual precision and the desired precision; and determining a new UTXO number in the target block at the desired precision based on the precision difference and the current UTXO number.

[0068] The accuracy difference is determined based on the desired accuracy and the actual accuracy. The accuracy difference reflects the change in UTXO accuracy. It is used to determine the new number of UTXOs at the desired accuracy.

[0069] Blockchain nodes determine the precision difference between the desired precision and the actual precision. Based on the precision difference and the current UTXO amount, a new UTXO amount in the target block at the desired precision is determined. This technical solution, based on the actual precision, desired precision, and current UTXO amount, determines a new UTXO amount in the target block at the desired precision, providing data support for adjusting the UTXO precision in the blockchain network.

[0070] In an optional embodiment, determining a new UTXO number in the target block at the desired precision based on the precision difference and the current UTXO number includes:

[0071] Based on the following formula, the new UTXO amount in the target block at the desired precision is determined according to the precision difference and the current UTXO amount;

[0072] U2 = U1 × 10 Pnew-Pold

[0073] Wherein, U2 represents the new UTXO amount in the target block at the desired precision; U1 represents the current UTXO amount; Pnew represents the desired precision; Pold represents the actual precision. Pnew-Pold represents the precision difference. Both Pnew and Pold are positive integers.

[0074] The above technical solution provides a specific and effective calculation method for determining the new UTXO amount at the desired precision in the target block, and provides data support for adjusting the UTXO precision in the blockchain network.

[0075] Figure 3 This is a schematic diagram of a blockchain-based transaction processing device according to an embodiment of this disclosure. This disclosure is applicable to situations where UTXO precision needs adjustment. The device can be implemented using software and / or hardware, and can implement the blockchain-based transaction processing method described in any embodiment of this disclosure.

[0077] The voting module 302 is used to control the block nodes in the blockchain network to vote on the voting proposal transaction and obtain the voting results when the actual accuracy is inconsistent with the expected accuracy.

[0078] The precision adjustment module 303 is used to adjust the number of available UTXOs according to the actual precision and the expected precision if the voting result is that the vote passes, so as to obtain a new number of UTXOs under the expected precision.

[0079] In this embodiment, the desired precision is extracted from the voting proposal transaction by the block nodes, and the actual precision of the available UTXO amount in the blockchain network is determined. If the actual precision differs from the desired precision, the block nodes in the blockchain network are controlled to vote on the voting proposal transaction. If the vote passes, the available UTXO amount is adjusted according to the actual precision and the desired precision to obtain a new UTXO amount with the desired precision. This provides technical support for adjusting the UTXO precision in the blockchain network, enabling adjustment of UTXO precision without affecting users' UTXO holdings, simplifying the UTXO precision adjustment method and reducing the difficulty of UTXO precision adjustment.

[0084] Wherein, U2 represents the new UTXO amount in the target block under the desired precision; U1 represents the current UTXO amount; Pnew represents the desired precision; Pold represents the actual precision; Pnew-Pold represents the precision difference; and Pnew and Pold are both positive integers.
