[0037] Figure 2 It is a flowchart of the application method of the blockchain technology of the present invention in financial payment settlement. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following further describes the embodiments of the present invention in detail with reference to the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0039] Example: The present invention provides an application system of blockchain technology in financial payment settlement, as Figure 1 shown, including a blockchain network module, a payment service access module, a smart contract execution module, a security guarantee module, and a real-time clearing and settlement module. The blockchain network module, the payment service access module, the smart contract execution module, the security guarantee module, and the real-time clearing and settlement module are electrically connected in sequence:

[0040] The blockchain network module is used to construct and maintain a distributed ledger and record financial payment settlement transaction information;

[0041] The payment service access module is used to dock with the payment system of financial institutions, obtain payment service data and transmit it to the blockchain network module;

[0042] The smart contract execution module is used to execute a preset smart contract on the blockchain network to realize the automated processing of financial payment settlement;

[0043] The security guarantee module is used to encrypt and store payment service data to ensure the security and immutability of transaction information;

[0044] The real-time clearing and settlement module is used to realize real-time clearing and settlement of payment services on the blockchain network, improving transaction efficiency.

[0045] As can be seen from the above, by constructing a blockchain network module, a payment service access module, a smart contract execution module, a security guarantee module, and a real-time clearing and settlement module, the system realizes the distributed recording, real-time acquisition and transmission, automated processing, security guarantee, and efficient clearing and settlement of financial payment and settlement, bringing a new solution to the financial industry and having significant beneficial effects.

[0046] Furthermore, in the blockchain network module, a consensus mechanism algorithm is introduced to improve the processing speed and fault tolerance of the blockchain network. The formula of the consensus mechanism algorithm includes:

[0047]

[0048] where V′ is the total number of votes, v i is the number of votes of the i-th node, and n is the total number of nodes participating in the consensus.

[0049] As can be seen from the above, in the blockchain network module, a consensus mechanism algorithm is introduced. This algorithm calculates the total number of votes, the number of votes of each node, and the total number of nodes participating in the consensus through a specific formula, thus significantly improving the processing speed and fault tolerance of the blockchain network. This makes the recording and storage of financial payment and settlement transaction information more efficient and stable, further enhancing the overall performance and reliability of the system.

[0050] Furthermore, the payment service access module adopts one or a combination of the following docking methods:

[0051] Docking with the development / test environment of the financial institution's payment system;

[0052] Building a simulation / shielding program for docking;

[0053] Verifying multiple business scenarios or different stages of a business processing flow simultaneously, adopting a flexible docking method.

[0054] As can be seen from the above, in the payment service access module, flexible and diverse docking methods are adopted, including docking with the development / test environment of the financial institution's payment system, building a simulation / shielding program for docking, and verifying multiple business scenarios or different stages of a business processing flow simultaneously. The above docking methods can ensure the accurate acquisition and efficient transmission of payment service data, improve the flexibility and adaptability of data access, and provide a strong guarantee for the smooth progress of financial payment and settlement.

[0055] Even further, the payment service access module adopts the clustering analysis algorithm in machine learning algorithms to preprocess payment service data to improve the accuracy and efficiency of data access. The algorithm formula of the clustering analysis algorithm:

[0056]

[0057] where d(x, c i ) is the distance from the data point x to the cluster center c i and x j is the j-th feature of the data point x, c ij is the j-th feature of the cluster center c i , and m is the total number of features.

[0058] As can be seen from the above, in the payment service access module, the clustering analysis algorithm in machine learning is used to preprocess payment service data. This algorithm calculates the distance from the data point to the cluster center through a specific formula and considers the values of the data point and the cluster center on each feature, thereby achieving accurate classification and preprocessing of the data. This method can significantly improve the accuracy and efficiency of data access, optimize data quality, and lay a solid foundation for subsequent financial payment settlement processing.

[0059] Furthermore, in the smart contract execution module, a formal language (including TLA+) is used to describe the smart contract, and a model checker is used to verify whether it satisfies specific properties (including security, deadlock-freedom, etc.). Its formulas include:

[0060]

[0061] where S is the state space, Init(s) is the initial state condition, Inv(s) is the invariant property, and Trans(s, s′) is the state transition relation;

[0062] At the same time, for the smart contract, a smart contract optimization algorithm is adopted to ensure the correctness and efficient execution of the smart contract. The formulas of the smart contract optimization algorithm include:

[0063] S next = TRANS(S current , A);

[0064] where S next is the next state, S current is the current state, A is the executed action, and TRANS is the state transition function.

[0065] As can be seen from the above, in the smart contract execution module, a formal language (including TLA+) is used to describe the smart contract, and a model checker is used to strictly verify whether it satisfies specific properties such as security and deadlock-freedom, ensuring the rigor and reliability of the smart contract. At the same time, an optimization algorithm is adopted for the smart contract, and efficient state transition and optimization of executed actions are achieved through specific formulas, thereby further improving the execution efficiency and correctness of the smart contract. These dual safeguard measures significantly enhance the automation level and credibility of financial payment settlement and reduce potential transaction risks.

[0066] Furthermore, in the security guarantee module, the payment business data is encrypted and stored using a more advanced encryption algorithm to protect the security and privacy of the payment business data. The formula of the encryption algorithm includes:

[0067] Enc(m1)·Enc(m2)=Enc(m1·m2);

[0068] where Enc(m) is the encrypted form of the plaintext m.

[0069] As can be seen from the above, in the security guarantee module, a more advanced encryption algorithm is used to encrypt and store the payment business data. This algorithm converts the plaintext data into ciphertext form through a specific formula, thus effectively protecting the security and privacy of the payment business data. Furthermore, it can prevent data leakage and illegal access, ensure the confidentiality and integrity of transaction information, and provide a solid security guarantee for financial payment settlement.

[0070] Furthermore, in the real-time clearing and settlement module, the shortest path algorithm in graph theory is used to find the optimal clearing path to reduce transaction latency and improve capital liquidity. The formula of the shortest path algorithm includes:

[0071]

[0072] where d[v] is the estimated value of the shortest path from the source point to vertex v, E is the edge set of the graph, and weight(u, v) is the weight of edge (u, v).

[0073] As can be seen from the above, in the real-time clearing and settlement module, the shortest path algorithm in graph theory is used to find the optimal clearing path. This algorithm calculates the estimated value of the shortest path from the source point to each vertex through a specific formula and comprehensively considers the edge set of the graph and the weights of the edges, thus being able to quickly determine the optimal clearing path. This method significantly reduces transaction latency, improves capital liquidity and utilization efficiency, ensures the timeliness and accuracy of financial payment settlement, and provides a more efficient and convenient payment settlement service for financial institutions and users.

[0074] Furthermore, the application system of a blockchain technology in financial payment settlement in the embodiment is compared with the existing financial payment settlement system (comparative example) in terms of effects, and the following table is obtained:

[0075]

[0076] As can be seen from the above table, the application system of blockchain technology in financial payment and settlement in this embodiment is superior to the existing financial payment and settlement systems in terms of processing speed, transaction cost, data security, transparency and traceability, real-time clearing and settlement, system scalability, and automation level, bringing new solutions and significant beneficial effects to the financial industry.
