Description

Technical Field

[0001] This invention relates to the field of blockchain cross-chain communication technology, specifically to a message delivery and receipt verification system and method for heterogeneous chain communication. Background Technology

[0002] The rapid development of blockchain technology has spawned a large number of heterogeneous blockchains with diverse functions, exhibiting significant differences in their core characteristics. These heterogeneous chains encompass various consensus mechanisms, including Proof-of-Work (PoW), Proof-of-Stake (PoS), and Delegated Proof-of-Stake (DPoS); data structures are categorized into account models and Unspent Transaction Outputs (UTXO) models; and network protocols include standards such as Hypertext Transfer Protocol (HTTP), WebSocket, and Dedicated Peer-to-Peer (P2P) protocols. Cross-chain communication, as a key technology for enabling data interaction and value transfer between different blockchains, has been widely applied in various fields such as financial clearing, supply chain collaboration, and cross-border supervision. Its core requirement is to achieve stable message transmission between heterogeneous chains, and the diversity of the core characteristics of heterogeneous chains becomes a fundamental technical prerequisite that cross-chain communication must address.

[0003] Current cross-chain message delivery technologies have significant limitations in their adaptation solutions to the core characteristics of heterogeneous chains. Existing adaptation layers mostly employ static, pre-defined rules, only adapting to a few fixed types of heterogeneous chains. They struggle to handle dynamic changes and diverse combinations in consensus mechanisms, data structures, and network protocols across different chains. Furthermore, existing technologies lack the ability to perceive and predict the real-time state of the target heterogeneous chain, failing to adjust delivery strategies based on dynamic information such as on-chain node load and consensus efficiency. This leads to message transmission delays due to consensus congestion or parsing failures due to data format and protocol incompatibility. In addition, most solutions lack effective adaptation feedback mechanisms, preventing iterative optimization of adaptation strategies based on delivery results. This further exacerbates the insufficient adaptability of cross-chain message delivery, severely impacting the stability and efficiency of cross-chain communication. Summary of the Invention

[0004] The purpose of this invention is to provide a message delivery and receipt verification system and method for heterogeneous chain communication, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a message delivery and receipt verification method for heterogeneous chain communication, the method comprising the following steps: A dynamic adaptation layer integrating a two-way adaptation feedback mechanism is constructed, and an optimized cross-chain communication protocol with embedded consensus prediction scheduling logic is adopted. The sender generates a cross-chain message packet and delivers it to the target heterogeneous chain through a dynamic adaptation layer. Through the synergy of the dynamic adaptation layer and the optimized cross-chain communication protocol, the transmission compatibility of the message packet between different heterogeneous chains is ensured, and message loss or parsing failure due to differences in chain characteristics is avoided. The sender refers to the entity that initiates the message in the sending chain; for example, if the sending chain is a blockchain deployed by a banking institution, the sender can be a business node within the bank responsible for initiating cross-chain clearing messages. The receiver performs the first round of verification based on a multi-layered verification association mechanism and synchronizes it to the node group for group verification; the verification result is determined by comparing the first round of verification results with the group verification results; the first round of verification achieves the initial verification of the message, and the group verification further improves the credibility of the verification results. The dual verification ensures that the message source is reliable and the content is complete. The recipient refers to the entity in the target heterogeneous chain that receives and verifies messages; for example, if the target heterogeneous chain is a blockchain deployed by a securities institution, the recipient can be the verification node within the securities institution that is responsible for receiving and verifying cross-chain messages. The node group refers to the group of nodes participating in cross-chain communication; for example, the nodes of various institutions participating in cross-chain communication, including sending chain nodes, target heterogeneous chain nodes and third-party regulatory nodes. The number of nodes is usually no less than 3 to ensure the objectivity of group verification. After verification is completed, the smart contract with built-in verification result association recording logic is triggered to record the receipt information and provide on-demand feedback based on the verification result; on-demand feedback can synchronize the verification result to the dynamic adaptation layer to provide data support for subsequent adaptation strategy optimization; The construction of the dynamic adaptation layer integrating a bidirectional adaptation feedback mechanism specifically includes: Continuously collect core characteristic information of the target heterogeneous chain and message delivery result data. The delivery result data includes message transmission success rate, parsing accuracy, and latency. A message transmission success rate of 95% or higher is considered qualified, a parsing accuracy of 98% or higher is considered qualified, and a latency of less than 500ms is considered qualified. The delivery effect is reflected intuitively through quantitative indicators. The core characteristic information of heterogeneous chains refers to the information of each heterogeneous chain in terms of consensus mechanism type, data structure specification, network protocol standard and node operating parameters; consensus mechanism type includes PoW, PoS, DPoS, etc., data structure specification includes account model, UTXO model, etc., network protocol standard includes HTTP, WebSocket, blockchain-specific P2P protocol, etc., and node operating parameters include node online rate, data processing rate, etc. Perform statistical analysis on the collected data to determine the matching degree between the adaptation strategy and the target heterogeneous chain; the statistical analysis can use conventional data statistical methods, such as calculating the deviation rate between the delivery result data and the preset standard value. The smaller the deviation rate, the higher the matching degree. The adaptation strategy refers to the set of consensus adaptation parameters, format conversion rules, and protocol docking methods pre-defined by the dynamic adaptation layer for the core characteristic information of the target heterogeneous chain; for example, for a PoW type consensus chain, the consensus adaptation parameter can be set to a longer consensus waiting time; for an account model data structure, the format conversion rule can be set to adapt the field mapping relationship. Based on the matching degree and the preset adjustment rule library, adaptation adjustment instructions are generated to optimize the consensus adaptation parameters, format conversion rules and protocol docking methods of subsequent messages. The preset adjustment rule library includes specific rules such as "shorten the message delivery interval when the transmission success rate is less than 90%" and "optimize the data field mapping rules when the parsing accuracy is less than 95%" to ensure the targeting of the adjustment instructions. The optimized cross-chain communication protocol with embedded consensus prediction and scheduling logic specifically includes: A consensus efficiency prediction model is established based on the historical consensus efficiency data of the target heterogeneous chain, real-time node load, and network bandwidth status. The historical consensus efficiency data refers to the number of messages that have completed consensus confirmation per unit time, the average consensus time, and the consensus success rate of the target heterogeneous chain in the past. Examples of historical consensus efficiency data include: the number of messages that have completed consensus confirmation in the past minute is 100-200, the average consensus time is 2-5 seconds, and the consensus success rate is over 99%. Real-time node load can be characterized by node CPU utilization and memory usage, and network bandwidth status can be characterized by data transmission rate. The model predicts the consensus processing capacity level of the target heterogeneous chain within a preset time window. For example, the preset time window can be 5 minutes, which means predicting the consensus processing capacity of the target heterogeneous chain within the next 5 minutes. The consensus efficiency prediction model can use a conventional machine learning model, such as a linear regression model, which is trained on historical data to make predictions. The consensus processing capability level refers to the level divided based on a preset rate range; The message delivery strategy is adjusted according to the consensus processing capability level: when the level is higher than the preset threshold, the real-time delivery mode is adopted; when the level is lower than the preset threshold, the time-sharing batch delivery mode is adopted. The real-time delivery mode means that the message is delivered immediately after it is generated, which is suitable for high-priority clearing messages; the time-sharing batch delivery mode means that the message is delivered in batches according to time. The process of the sender generating a cross-chain message packet specifically includes: The sender generates a key pair using an asymmetric encryption algorithm. The key pair includes a private key and a public key. The private key is used for digital signature of the message, and the public key is synchronized to the node community and the target heterogeneous chain. The sender performs a hash operation on the original message to generate a unique hash value, and assigns a unified association identifier to the digital signature, hash value and original message. The associated identifier, digital signature, hash value, and original message are associated and encapsulated to form a cross-chain message packet.

[0006] The multi-layered verification association mechanism specifically includes: The recipient extracts the digital signature, hash value, and message text corresponding to the associated identifier in the cross-chain message packet to complete the first round of verification, including signature verification and hash value comparison; The recipient synchronizes the association identifier and the first-round verification result to the node group. The node group performs a second verification on the message packet based on the association identifier, forming a group verification result. The results of the first round of verification are compared with the results of the group verification. If they match, the verification is deemed successful; otherwise, the verification is deemed unsuccessful.

[0007] The logic for associating the verification result of the smart contract with records specifically includes: The smart contract has pre-set receipt record fields, including association identifier, sender information, receiver information, first round verification result, group verification result, and verification time; After the recipient completes the verification, the smart contract is triggered through an on-chain transaction. The smart contract binds and records various verification results with associated identifiers, and writes the receipt data into the target heterogeneous chain block. The smart contract establishes a verification result query index, with the association identifier as the core keyword, supporting cross-chain node groups and related entities to query and verify on demand. When verification fails, the smart contract records the failure nodes and reasons at each layer, generates failure tracing information, and sends it back to the sender.

The message delivery module is used by the sender to generate cross-chain message packets and deliver them to the target heterogeneous chain through the dynamic adaptation layer. The message verification module is used by the receiver to perform the first round of verification based on a multi-layer verification association mechanism, and synchronize it to the node group for group verification, comparing the first round of verification results with the group verification results to determine the final verification result. The receipt management module is used to trigger a smart contract with built-in verification result association recording logic after verification is completed, record receipt information, and realize on-demand feedback based on the verification results.

[0009] The dynamic adaptation module includes a strategy evaluation unit, a strategy adjustment unit, and a scheduling decision unit. The strategy evaluation unit continuously collects core characteristic information and historical message delivery results data of the target heterogeneous chain, and determines the matching degree between the current adaptation strategy and the target heterogeneous chain through statistical analysis. The strategy adjustment unit generates adaptation adjustment instructions based on the matching degree judgment result of the strategy evaluation unit and in combination with a preset adjustment rule base, and optimizes the consensus adaptation parameters, format conversion rules and protocol docking methods for subsequent message delivery. The scheduling decision unit constructs a consensus efficiency prediction model, and dynamically selects and executes real-time delivery mode or time-sharing batch delivery mode according to the consensus processing capability level of the target heterogeneous chain.

[0010] The message delivery module includes a message encapsulation unit and a message sending unit; The message encapsulation unit is used by the sender to perform secure encapsulation operations on the original message, including generating a digital signature, calculating a hash value, assigning a unified association identifier, and performing association encapsulation to form a standard cross-chain message packet; the message sending unit is used to submit the encapsulated cross-chain message packet to the dynamic adaptation module to start the delivery process to the target heterogeneous chain.

[0011] The message verification module includes a first verification execution unit, a group consensus unit, and a result arbitration unit; The initial verification execution unit is used by the receiver to perform the first round of verification on the cross-chain message packet, specifically including the validity verification of the digital signature and the integrity comparison of the message hash value; the group consensus unit is used to synchronize the association identifier and content of the message to be verified to the node group, organize the node group to perform independent verification, and summarize to form the group verification result; the result arbitration unit is used to compare the first round verification result with the group verification result, and determine the final verification result of the message based on the consistency between the two. The receipt management module includes a receipt recording unit and a feedback triggering unit; The receipt recording unit is triggered after verification to record key information such as association identifier, verification result, and verification time as a structured receipt in the block of the target heterogeneous chain; the feedback triggering unit is used to execute feedback logic based on the final verification result; when the verification passes, result query is supported; when the verification fails, traceability information containing the failure node and reason is generated and fed back to the sender and dynamic adaptation module.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention improves the problem of insufficient heterogeneous chain adaptability by integrating a dynamic adaptation layer with a bidirectional adaptation feedback mechanism and an optimized cross-chain communication protocol with embedded consensus prediction scheduling logic; it ensures the authenticity and integrity of messages through a multi-layer verification association mechanism; and it effectively improves the efficiency, security, and reliability of cross-chain message delivery and receipt verification by realizing the immutable recording and traceable query of receipt information through smart contracts.

The message delivery and receipt verification system for heterogeneous chain communication according to claim 8, characterized in that: The message delivery module includes a message encapsulation unit and a message sending unit; The message encapsulation unit is used by the sender to perform secure encapsulation operations on the original message, including generating a digital signature, calculating a hash value, assigning a unified association identifier, and performing association encapsulation to form a standard cross-chain message packet; the message sending unit is used to submit the encapsulated cross-chain message packet to the dynamic adaptation module to start the delivery process to the target heterogeneous chain.

10. The message delivery and receipt verification system for heterogeneous chain communication according to claim 9, characterized in that: The message verification module includes a first verification execution unit, a group consensus unit, and a result arbitration unit; The initial verification execution unit is used by the receiver to perform the first round of verification on the cross-chain message packet, specifically including the validity verification of the digital signature and the integrity comparison of the message hash value; the group consensus unit is used to synchronize the association identifier and content of the message to be verified to the node group, organize the node group to perform independent verification, and summarize to form the group verification result; the result arbitration unit is used to compare the first round verification result with the group verification result, and determine the final verification result of the message based on the consistency between the two. The receipt management module includes a receipt recording unit and a feedback triggering unit; The receipt recording unit is used to be triggered after verification is completed, and to record key information such as association identifier, verification result, and verification time as a structured receipt into the block of the target heterogeneous chain; The feedback triggering unit is used to execute feedback logic based on the final verification result; when the verification passes, it supports result query; when the verification fails, it generates traceability information containing the failure node and the reason, and feeds the information back to the sender and the dynamic adaptation module.
