DETAILED DESCRIPTION

The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

The application provides users with corresponding operation entrances for them to choose to agree or reject the results of automated decisions; if the user chooses to reject, the expert decision-making process will be entered.

[0035] It should be noted that the blockchain transaction processing method, device, equipment, storage medium and program product provided in this application can be used in the blockchain field, and can also be used in any field other than blockchain. The application field of the blockchain transaction processing method, device, equipment, storage medium and program product in this application is not limited.

[0036] In this application, it should be understood that the terms involved have the following meanings:

[0037] Blockchain: Blockchain is a distributed ledger technology that connects data blocks in an orderly manner and uses cryptography to ensure that they cannot be tampered with or forged. Transaction confirmation on the blockchain is completed by all nodes on the blockchain, and its consistency is guaranteed by the consensus algorithm. In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is a distributed ledger that is tampered with and cannot be forged using cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm that uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data.

[0038] Smart Contract: A smart contract is a computer protocol designed to disseminate, verify or execute contracts in an information-based manner. It is an autonomous, self-executing code that automatically executes the terms and conditions contained therein without human intervention. Smart contracts are designed to run in a decentralized network, enabling reliable, secure and transparent transactions. The decentralized and tamper-proof nature of blockchains makes it possible to implement smart contracts on blockchains.

[0039] Cross-chain technology is an emerging technology in the blockchain field that aims to solve the interoperability problem between different blockchain networks. With the diversification of blockchain applications and the expansion of the ecosystem, cross-chain technology has become increasingly important because it allows communication, data sharing and asset transfer between different blockchain networks.

[0040] At present, some solutions based on cross-chain interaction have been proposed in related technologies, such as introducing notaries or using off-chain methods such as side chains. These methods are very restrictive. For example, in the notary mechanism, it is difficult for the same notary to be recognized in multiple blockchains. Similarly, side chains lack universality when facing different blockchains. Every time a blockchain conducts a cross-chain transaction, it needs to understand off-chain factors based on the transaction object, which is inefficient and lacks standardization.

[0041] The inventor found through research that the reason for the above problems is the lack of a universal and standardized cross-chain interaction method applicable to most blockchains. The existing cross-chain method requires the help of off-chain factors such as notaries, and different blockchains are applicable to different off-chain factors. Each time before a cross-chain occurs, it needs to be verified within the blockchain, which takes a lot of time. The inventor therefore thought that the cross-chain can be managed from the execution level of the cross-chain behavior, that is, it can limit whether the cross-chain related smart contracts are effective, and the nodes within the chain will vote, and decide whether the contract is effective according to the voting results, ensuring that safe cross-chain transactions can be executed, and unsafe cross-chain transactions cannot be executed because the contract cannot take effect, thereby ensuring the security of the cross-chain. In addition, nodes with cross-chain audit capabilities can be selected from the nodes within the blockchain as director nodes, and the director nodes vote on the cross-chain content in the smart contract, which can not only improve the accuracy of decision-making, but also reduce the burden on other nodes and improve the efficiency of cross-chain management.

[0042] Figure 1 A schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, blockchain A may include nodes A1, A2, ..., An, and blockchain B may include nodes B1, B2, ..., Bm. The nodes in blockchain A may conduct cross-chain transactions with the nodes in blockchain B.

[0043] The blockchain transaction processing method, device, equipment, storage medium and program product provided in this application are intended to solve the above technical problems of the prior art.

[0044] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 2 A flowchart of a blockchain transaction processing method provided in an embodiment of the present application. Figure 2 As shown, the method includes:

[0046] Step S201, obtain the cross-chain contract.

[0047] Among them, cross-chain contracts are smart contracts related to cross-chain transactions.

[0048] The blockchain transaction processing method provided in the embodiment of the present application can be applied to a blockchain, which may include ordinary nodes and director nodes. The blockchain may be, but is not limited to, a public chain, a consortium chain, or a private chain.

[0049] Specifically, the smart contract in the blockchain can be identified, and whether the smart contract to be identified is a cross-chain contract can be determined by identifying the transaction objects contained in the smart contract and identifying the interface or library called by the smart contract.

[0050] Step S202, extracting intra-chain slices and cross-chain slices from the cross-chain contract.

[0051] Among them, the intra-chain slice contains contract content that is not related to cross-chain, and the cross-chain slice contains contract content related to cross-chain.

[0052] Specifically, based on the content of the cross-chain contract, the part that is not related to the cross-chain can be extracted to form an intra-chain slice, and the part that is related to the cross-chain can be extracted to form a cross-chain slice. For example, the internal functions and variables defined in the cross-chain contract can be identified. The content involved in this part is usually irrelevant to the cross-chain and can be extracted into the intra-chain slice. For another example, the part related to the intra-chain assets in the cross-chain contract can be identified. The content involved in this part is related to the cross-chain and can be extracted into the cross-chain slice.

[0053] Step S203, sending the in-chain slices to ordinary nodes and council nodes to obtain the in-chain voting results of ordinary nodes and council nodes on the in-chain slices.

[0054] Specifically, after extracting the in-chain slices and cross-chain slices, the in-chain slices can be broadcast to all nodes including ordinary nodes and director nodes. Users corresponding to each node can access the blockchain through terminal devices to obtain the in-chain slices from the node blocks and vote. The blockchain server can receive the voting results returned by each node, which may include affirmative or negative votes.

[0055] Step S204, sending the cross-chain slice to the council node to obtain the cross-chain voting result of the council node on the cross-chain slice.

[0056] A director node may also be referred to as a governance node, which refers to a node with specific authority and responsibility in a blockchain. In an embodiment of the present application, a director node may be a pre-set node with decision-making power for cross-chain transactions.

[0057] Step S205, determine the effectiveness method of the cross-chain contract based on the intra-chain voting results and the cross-chain voting results.

[0058] Specifically, the effectiveness rules of the cross-chain contract can be pre-set according to the voting behavior of the blockchain nodes. After receiving the voting results returned by each node, it can be determined whether the cross-chain contract is effective based on whether the voting results meet the effectiveness rules.

[0059] For example, a threshold can be set based on the number of affirmative votes in the voting results or the proportion of nodes that voted in favor to the total nodes of the blockchain. If the value in the voting results exceeds the threshold, it can be determined that the cross-chain contract can take effect.

[0060] The blockchain transaction processing method provided in this embodiment can obtain cross-chain contracts and extract intra-chain slices and cross-chain slices. The intra-chain slices containing contract content unrelated to the cross-chain can be sent to the ordinary nodes and the director nodes of the blockchain, and the cross-chain slices containing the contract content related to the cross-chain can be sent to the director nodes. The blockchain can receive the voting results returned by the ordinary nodes and the director nodes, and determine the effectiveness of the cross-chain contract according to the voting results. Among them, by extracting the cross-chain slices of the contract, it can make it easier for the director nodes with corresponding permissions to pay attention to the content of the cross-chain transaction. The director nodes can customize the settings, which can not only ensure that the cross-chain transaction is effective under review and improve the security of the cross-chain transaction, but also provide a new type of adjustable cross-chain audit method to expand the flexibility of cross-chain audit.

[0061] In one embodiment, the method of determining the effectiveness of the cross-chain contract according to the intra-chain voting results and the cross-chain voting results includes:

[0062] If the number of affirmative votes in the intra-chain voting results is greater than or equal to the first threshold and the number of affirmative votes in the cross-chain voting results is greater than or equal to the second threshold, the cross-chain contract is determined to be effective.

[0063] Alternatively, if Figure 3 As shown, after obtaining the voting results returned by the ordinary nodes and the director nodes, the number of affirmative votes in the intra-chain voting results and the number of affirmative votes in the cross-chain voting results can be calculated respectively, and the quantitative relationship between the number of affirmative votes in the intra-chain voting results and the preset first threshold value can be compared. If the number of affirmative votes in the intra-chain voting results is less than the first threshold value, all cross-chain contracts will not take effect; if the number of affirmative votes in the intra-chain voting results is greater than or equal to the preset first threshold value, it is possible to continue to compare whether the number of affirmative votes in the cross-chain voting results is greater than or equal to the preset second threshold value. If so, it can be determined that the cross-chain contract is effective.

[0064] By setting the first threshold, whether the cross-chain contract is effective can be determined based on the affirmative votes in the intra-chain voting results. The intra-chain voting results are generated based on the intra-chain slices. If the part of the cross-chain contract related to the chain cannot be passed by the majority of the intra-chain nodes, it can be regarded as a major problem with the contract. There is no need to pay attention to the cross-chain part and it can be directly confirmed to be ineffective, thereby improving the audit efficiency.

[0065] Alternatively, if Figure 3 As shown, if the number of affirmative votes in the intra-chain voting results is greater than or equal to the preset first threshold, but the number of affirmative votes in the cross-chain voting results is less than the second threshold, it can be confirmed that the slices related to the intra-chain in the cross-chain contract are effective, and the cross-chain slices related to the outside chain are not effective.

[0066] If the number of affirmative votes in the intra-chain voting results reaches the first threshold, it can be regarded that the cross-chain contract has been reviewed and approved by the majority of nodes in the intra-chain part. However, if the number of affirmative votes in the cross-chain voting results does not reach the second threshold, it can be regarded that more director nodes believe that there are problems in the cross-chain slice of the contract. At this time, the intra-chain slice of the cross-chain contract can be made effective, and the contract content of the intra-chain part can be executed first, and the cross-chain slice will not take effect for the time being. In this way, the cross-chain contract can be partially effective and the execution process of cross-chain transactions can be flexibly controlled.

[0067] Furthermore, if it is determined that the cross-chain slice is not effective, the in-chain slice of the cross-chain contract can be executed and the next voting conditions can be set; in response to meeting the next voting conditions, the cross-chain voting results of the council nodes on the cross-chain slice are re-obtained, and the effectiveness method of the cross-chain slice is determined based on the re-obtained cross-chain voting results.

[0068] The voting condition may be a time condition. For example, if the director node votes to confirm that the cross-chain slice is not effective for the time being, the next voting time for the cross-chain slice can be set; when the next voting time arrives, the director node's voting result for the cross-chain slice is obtained again. If the number of votes in favor in the voting result is greater than or equal to the second threshold, it can be determined that the cross-chain slice is effective; if the number of votes in favor is still less than the second threshold, other processing can be performed (such as generating an abnormality report, notifying relevant personnel, etc.).

[0069] In some possible implementations, the voting condition may also be an external condition of the blockchain. Taking the cross-chain transaction between the node in blockchain A and the node in blockchain B as an example, the reason why the number of affirmative votes in the voting result of the council node in blockchain A for the cross-chain slice is less than the second threshold may be related to blockchain B. For example, the node in blockchain A meets the requirements of the cross-chain transaction, but the node in blockchain B does not meet the requirements of the cross-chain transaction (such as the node identity is not verified). Whether the node in blockchain B meets the cross-chain transaction requirements can be set as the next voting condition. When the node in blockchain B meets the requirements, the council node in blockchain A votes again.

[0070] By setting the next voting conditions, the part of the cross-chain contract that has not yet been determined to take effect can get another voting opportunity. If it passes after the second vote, the part can take effect, thereby improving the efficiency of contract execution.

[0071] In one embodiment, Figure 4 As shown, the effectiveness of the cross-chain contract is determined based on the intra-chain voting results and the cross-chain voting results, including:

[0072] Step S401, calculate the number of ordinary votes in favor and the number of directors' votes in favor according to the intra-chain voting results.

[0073] Among them, the number of ordinary votes in favor may refer to the total number of votes in favor cast by ordinary nodes for in-chain slices, and the number of director votes in favor may refer to the total number of votes in favor cast by director nodes for in-chain slices.

[0074] Step S402, according to the voting weights corresponding to the ordinary nodes and the director nodes, the number of ordinary approval votes and the number of director approval votes are weightedly calculated to obtain the approval score.

[0075] For example, if the number of ordinary votes is P and the number of director votes is Q, the approval score R can be expressed as: R = k1 × P + k2 × Q. Where k1 can represent the voting weight of an ordinary node, and k2 can represent the voting weight of a director node.

[0076] Step S403: If the approval score is greater than the preset third threshold, it is determined that the intra-chain slice of the cross-chain contract is effective.

[0077] It is understandable that different voting weights can be set for different types of blockchain nodes, and voting weights can affect whether the slices in the chain can take effect. By setting weights, the influence of ordinary nodes and council nodes on the chain part of cross-chain transactions can be flexibly adjusted to ensure the rationality of cross-chain transactions.

[0078] Optionally, before weighted calculation of the number of ordinary approval votes and the number of director approval votes is performed according to the voting weights corresponding to the ordinary nodes and the director nodes, the following is further included:

[0079] Determine the associated nodes according to the cross-chain contract. The associated nodes are ordinary nodes or director nodes. Increase the voting weight corresponding to the associated nodes.

[0080] Among them, the associated node can be a node that has a certain relationship with the cross-chain contract.

[0081] It is understandable that the associated node can be a common node or a director node. After the associated node is determined, the voting weight of the associated node can be increased.

[0082] In some possible implementations, such as Figure 5 As shown, determining the associated nodes according to the cross-chain contract may include:

[0083] Step S501, identifying the intra-chain transaction node in the cross-chain contract.

[0084] Step S502, obtaining the identity information of the transaction node within the blockchain from the blockchain.

[0085] Step S503: determining associated nodes from common nodes and director nodes according to identity information.

[0086] Exemplarily, the objects involved in the cross-chain transaction can be determined based on the content of the cross-chain contract, including the transaction nodes within the chain and the transaction nodes outside the chain. The identity information of the transaction nodes within the chain is then queried based on the blockchain, and which nodes are associated with the transaction nodes within the chain are further determined based on the identity information.

[0087] In this way, on the basis of the above voting method, the associated nodes related to the cross-chain transaction behavior can be further distinguished, and the voting weight of the associated nodes can be increased, so that the associated nodes can have higher decision-making power over cross-chain transactions.

[0088] In one embodiment, obtaining a cross-chain contract may include: obtaining a smart contract to be identified; detecting whether there is preset cross-chain information in the smart contract, and if so, determining the smart contract as a cross-chain contract. The cross-chain information includes at least one of an off-chain object name, a cross-chain interface, a cross-chain library, and a cross-chain route.

[0089] Exemplarily, it is possible to detect whether the blockchain transaction executed by the smart contract contains transaction objects that are not from the current blockchain. If so, it means that the smart contract involves cross-chain transactions.

[0090] For example, the cross-chain call behavior of the smart contract can also be detected. If there is a cross-chain call behavior in the blockchain transaction executed by the smart contract, the smart contract may also involve a cross-chain transaction. For example, cross-chain behavior can be implemented through some frameworks, and the event records of these frameworks can be detected to determine whether the smart contract is a cross-chain call behavior.

[0091] In some possible implementations, cross-chain behaviors can also be detected in other ways. For example, cross-chain transactions usually involve transaction nodes on chain A sending messages to chain A routers to request interactions with chain B. Blockchain routing can be detected to determine whether smart contracts are related to cross-chain transactions. For another example, SDK detection can be used to determine whether cross-chain call behaviors occur.

[0092] Through the above-mentioned methods, it is possible to accurately determine whether a smart contract involves content related to cross-chain transactions, thereby quickly identifying cross-chain contracts and improving the processing efficiency of blockchain cross-chain transactions.
