Description

Technical Field

[0001] This invention relates to the field of blockchain regulatory technology, and in particular to a blockchain-based regulatory method and system. Background Technology

[0002] Existing centralized regulatory systems are widely used in finance, healthcare, and supply chain sectors, ensuring data security, compliance, and transparency through centralized management and monitoring. However, these systems also face challenges and limitations. For example, centralized regulatory systems rely on big data and artificial intelligence technologies to analyze massive amounts of data to identify risks, monitor abnormal behavior, and predict potential problems. Anti-money laundering (AML) systems in the financial sector analyze customer transaction data to identify potential money laundering activities.

[0003] In summary, existing centralized regulatory systems have the following drawbacks:

[0004] (1) Single point of failure risk. Centralized systems rely on a single data storage and management center. If this center fails (such as a server crash or network outage), the entire system will be unable to function properly. This risk of a single point of failure is particularly prominent in centralized architectures. If a centralized database is maliciously attacked or its data is corrupted, it could lead to large-scale data loss and business interruption.

[0005] (2) Data privacy and security issues. Centralized systems store and process data on a small number of servers or data centers, making them easy targets for attackers. If these servers are compromised, it could lead to large-scale data breaches. In centralized systems, user data is often controlled by a central authority, leaving users with limited control over their data and increasing the risk of privacy problems.

[0006] (3) High operating costs. Maintaining and operating a large centralized regulatory system requires a huge investment in infrastructure, including servers, storage devices, and network equipment. In addition, dedicated personnel are needed for system maintenance and upgrades. Centralized systems need to meet various compliance requirements, such as GDPR and CCPA, which often requires a significant investment of resources for compliance review, monitoring, and reporting.

[0007] (4) Transparency and Trust Issues. In centralized systems, the data processing and results are often controlled by the central institution, making it difficult for outsiders to verify the authenticity of the data and the fairness of the processing. This may lead to insufficient transparency in the system, undermining the trust of users and partners. Centralized regulatory systems may lead to information asymmetry, and the information gap between regulatory agencies and those being regulated may affect the effectiveness and fairness of decision-making.

[0008] In summary, there is currently a lack of regulatory methods and systems that mitigate or eliminate the risks of centralization while taking into account data privacy. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a blockchain-based regulatory method and system, so as to solve or partially solve the problems of high failure risk and inadequate data privacy protection in centralized regulatory systems.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0022] As a preferred technical solution, the data monitoring plugin monitors data by subscribing to a message queue.

[0023] As a preferred technical solution, in step S8, the selection of the level method is based on the carrying capacity of the regulatory blockchain.

[0024] As a preferred technical solution, the regulatory blockchain is directly connected to both the regulated blockchain and the regulated system, or the regulatory blockchain is connected to both the regulated blockchain and the regulated system through the data supervision plugin.

[0025] Another aspect of the present invention provides a blockchain-based regulatory system for implementing the aforementioned blockchain-based regulatory method, wherein the blockchain-based regulatory system comprises:

[0026] A blockchain management platform is used to manage regulatory blockchains, including setting up nodes in the regulatory blockchain network, deploying smart contracts on the regulatory blockchain network, and monitoring and managing the regulatory blockchain.

[0027] The regulatory service module is used to obtain data that needs to be regulated from the regulated blockchain and the regulated system through the data regulatory plugin, perform regulatory service management operations and display regulatory data through the regulatory front end, and connect with the regulatory blockchain through the regulatory back end to send regulatory instructions.

[0028] The regulatory blockchain module is used to operate a blockchain network that regulates smart contracts.

[0029] As a preferred technical solution, the regulatory service module includes:

[0030] The data supervision plugin is used to enable pluggable data integration monitoring, on-demand integration, and indicator calculation, provided that the supervised entity allows it.

[0031] A blockchain plugin for enabling information subscription on the blockchain side;

[0051] Figure 1 This is a schematic diagram of a blockchain-based regulatory method in the embodiments;

[0052] Figure 2 This is a schematic diagram of a blockchain-based regulatory system in the embodiment. Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0054] To address the problems existing in the aforementioned prior art, this embodiment provides a blockchain-based regulatory method and system, see [link to relevant documentation]. Figure 2 The system mainly includes:

[0055] (1) Regulatory blockchain, used to provide storage for regulatory data and the ability to run regulatory smart contracts. The blockchain network that operates regulatory smart contracts, conducts blockchain data consensus, stores data on the regulatory chain, and executes regulatory smart contracts.

[0056] Specifically, regulating blockchain includes smart contracts and distributed ledger modules.

[0057] a) Smart contracts include: information registration contracts, used to register data that needs to be regulated on the regulatory blockchain; information storage contracts, used to encrypt and store data that needs to be regulated on the regulatory blockchain; regulatory data query contracts, used to provide the ability to query data on the regulatory blockchain; data audit contracts, used to provide the ability to audit data on the regulatory blockchain; message notification contracts, used to provide notification services for key information on the regulatory blockchain that needs to be notified to regulatory services; and content regulation contracts, used to regulate and control content on the regulatory blockchain that is agreed to be regulated.

[0058] b) Regulatory services, which provide the ability for the regulatory blockchain to effectively connect with other regulated systems. This involves obtaining the necessary regulatory data through a data regulatory plugin, managing regulatory services and displaying regulatory information through the regulatory front-end, and connecting with the regulatory blockchain through the regulatory back-end to send regulatory instructions.

[0059] Specifically, the regulatory services include: data monitoring plugins, regulatory front-end, and regulatory back-end.

[0060] a) Data oversight plugin: Provides pluggable data integration and monitoring plugins. Within the oversight service, it allows configuration of oversight objects, content, and rules, enabling on-demand integration and indicator calculation, provided the oversight object permits. Specifically, it includes a blockchain plugin for information subscription on the blockchain side; a log plugin for information collection on the log service side; and a database plugin for information integration on the application database side.

[0061] b) The regulatory front end is divided into a management platform and a data display platform. The management platform is for managers of regulatory services and can configure information on the corresponding regulated objects and rules for regulatory subscriptions; the data display platform intuitively displays key regulatory information on the regulatory chain and regulatory services.

[0062] c) The regulatory backend is divided into data statistics service, content supervision service, early warning notification service, and data subscription service. The data statistics service provides configuration management for data statistics based on data statistics rules and can be used for data visualization on the data display platform. The content supervision service configures and specifies the content on the blockchain that needs to be regulated. The early warning notification service provides notification and early warning capabilities for regulatory personnel and supports integration with external messaging services. The data subscription service is responsible for subscribing to information that needs to be uploaded to the blockchain, including configuring subscription rules and managing subscribed content.

[0063] (3) A blockchain management platform for managing regulatory blockchains. Specifically, it is used to manage the regulatory blockchain network, including setting up nodes for the regulatory blockchain network, deploying smart contracts on the regulatory blockchain network, and monitoring and maintaining the regulatory blockchain.

[0064] Furthermore, the system may also include:

[0065] (4) Privacy computing module, from the perspective of data security, further protects the security of the regulated data.

[0066] Therefore, the privacy computing module includes a secure multi-party computation unit, a federated learning unit, and a trusted execution environment unit.

[0067] a) Secure multi-party computation (MPC) allows multiple parties to collaboratively compute an objective function without the need for a trusted third party. Each party only receives its own computation result and cannot obtain input data from any other party through interactive data during the computation process. Secure MPC technology enables multiple non-trusted entities to perform efficient data fusion computations and obtain accurate results while maintaining data confidentiality, without disclosing any private data, thus offering extremely high security.

[0068] b) Federated learning is a model in which multiple participants exchange intermediate computational results in a privacy-preserving manner, while ensuring that their original data is not disclosed, and collaboratively complete a machine learning task. By adding security design to the model information exchange process between participants, federated learning ensures that the constructed global model can protect user privacy and data security while making full use of data from multiple parties. It is an important computational paradigm for solving data silo and data security problems, emphasizing that the model moves while the data remains stationary, and that data is usable but not visible.

[0069] c) Trusted Execution Environment (TEE): This involves constructing a secure and trusted region within the central processing unit (CPU) through hardware and software methods, ensuring the confidentiality and integrity of its internal loading processes and data. A TEE is an isolated execution environment that provides trusted applications running on the device with a higher level of security than ordinary operating systems and richer functionality than traditional security elements. Through technologies such as process-level isolation, architecture-level isolation, and virtualization-level isolation, a TEE provides users with an execution space that offers enhanced security and richer functionality than conventional security chips, providing confidentiality and integrity protection for code and data.

[0070] Building upon the existing regulatory system, this embodiment also provides a blockchain-based regulatory method, see [link to relevant documentation]. Figure 1 The method includes the following steps:

[0071] Step S1: Deploy a regulatory blockchain using a blockchain management platform. Deploying a regulatory blockchain allows control over the participation of each node in the regulatory chain.

[0072] Step S2: Deploy the smart contracts required on the regulatory blockchain using the blockchain management platform. The smart contracts require consensus among the participating nodes.

[0073] Step S3: Deploy the regulatory service. When deploying the regulatory service, the service is debugged according to the standard interface specification of the smart contract on the regulatory blockchain.

[0074] Step S4: Deploy the regulated blockchain using a blockchain management platform. During deployment, the participants in each node of the regulated blockchain can be controlled.

[0075] Step S5: Deploy the regulated system, which can be directly connected to the regulatory chain or connected through a regulatory plugin;

[0076] Step S6: Deploy the regulatory plugin on the regulated blockchain and the regulated system. The regulatory plugin is compatible with the technology stack of mainstream blockchains and other services. Deployment is completed by modifying the configuration file.

[0077] Step S7: Subscribe to information in the regulated blockchain and the regulated system through the data supervision plugin. The data supervision plugin supports subscribing to a large amount of regulatory data in the form of a message queue.

[0078] Step S8 involves registering the regulated data on the regulatory blockchain via a data subscription service. The subscription service can select a corresponding registration mode based on the blockchain's capacity. Specific registration modes include original data registration and data notarization registration. Original data registration registers the raw information of the data on the blockchain network. This is suitable for scenarios where the raw data information needs to be readily accessible on the blockchain network. It has a relatively low data capacity; preferably, a single registration should not exceed 1KB. Data notarization registration processes the original data using a hash algorithm and registers the result on the blockchain. This is suitable for scenarios where sensitive data needs to be anonymized. Since hashing the data results in a fixed-length string, it can support a single registration size of 1KB to 1GB.

[0079] Step S9: Determine whether the regulated content needs to be notified externally. If so, notify externally via a message notification contract; otherwise, the process ends. If the regulated content involves encryption, the determination will be made after decryption. The message notification service supports multiple notification modes, including SMS and email.

[0080] This embodiment adopts a blockchain-based governance model, using blockchain to supervise other blockchain systems and application services. Based on the immutability of data on the blockchain, the validity of the data of the supervised objects is ensured; based on the distributed network characteristics of the blockchain, the unavailability of the entire supervision system due to single points of failure is avoided, improving the overall system's fault tolerance and security. This method and system have the following advantages:

[0081] (1) By adopting distributed technology, we can get rid of the dependence on traditional centralized platforms and use blockchain to store and manage the key data under supervision.

[0082] (2) By setting up a blockchain management platform and building a dedicated blockchain network for supervision, unified supervision of multiple regulated blockchains and regulated systems can be achieved.

[0083] (3) All regulated data operation processes are recorded by blockchain, taking advantage of the blockchain's chain-like data characteristics that are difficult to modify, to ensure data security and immutability.

[0084] (4) The execution of regulatory rules is entirely handled by smart contracts on the blockchain, and the execution process is also recorded and traced through the blockchain, reducing the possibility of human intervention and making the regulatory process traceable.

[0085] (5) Using cryptographic algorithms, generate system or individual accounts on the regulatory blockchain, including key information such as their blockchain certificates and addresses.

[0086] (6) All data registered on the regulatory blockchain and operations on smart contracts must be signed using system or personal certificates to prevent the possibility of others signing on behalf of others.

[0087] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
