Description

Technical Field

[0001] The present invention belongs to the field of domain name system and blockchain technology, and specifically relates to a blockchain resource directory addressing and parsing method and system based on the domain name system. Background Art

[0002] The Domain Name System (DNS) is one of the basic services of the Internet. It provides people with an easy-to-understand and easy-to-remember way to access Internet resources. DNS enables users to easily access various network services by converting human-readable domain names (such as `www.example.com`) into IP addresses that computers can understand.

[0003] The working principle of DNS is based on a layered architecture, which mainly includes the following levels: 1) Root node (Root): This is the highest level of the DNS system, responsible for directing queries to top-level domain names (such as `.com`, `.org`). 2) Top-level domain name (TLD): such as `.com`, `.org` or country code top-level domain name (ccTLD, such as `.cn`). 3) Second-level domain name: subdomain under the top-level domain name, such as `example` in `example.com`. 4) Third-level domain name and others: further subdivided subdomains, such as

[0004] The success of the DNS system lies in its high scalability and recursive query mechanism, which enables users to obtain resource location information related to domain names through layers of queries.

[0005] In recent years, blockchain technology has developed rapidly and has gradually become an important infrastructure in a variety of application scenarios. Blockchain is a decentralized distributed ledger technology with the characteristics of immutability, transparency and trustlessness. The application of blockchain covers areas such as cryptocurrency, smart contracts, supply chain management, digital identity, and government approval.

[0006] However, with the widespread application of blockchain technology, the following challenges have emerged:

[0007] 1) Blockchain isolation: Currently, most blockchain systems are independent of each other and lack effective interoperability. Different blockchain networks usually have differences in technology stacks, consensus mechanisms, and data formats, making cross-blockchain resource access and management complex and inconvenient. Currently, cross-chain technology is constantly developing to solve the problem of blockchain isolation. However, existing cross-chain technologies focus more on data transmission and interoperability protocols rather than global addressing of resources. Existing cross-chain technologies include:

[0008] a) Cross-chain Bridges: These technologies allow the transfer of assets or data between different blockchains, but they usually require pre-configuration and are complex.

[0009] b) Interoperability protocols: Projects such as Polkadot and Cosmos are committed to establishing cross-chain interoperability standards, but they mainly focus on compatibility at the protocol layer rather than user-friendly resource addressing methods.

[0010] 2) Difficulty in resource addressing: On the Internet, users can easily access different network resources through DNS. However, in the blockchain field, there is no similar global addressing system, and it is difficult for users to conveniently access and manage cross-chain resources. In the blockchain field, the addressing and resolution of resources usually rely on mechanisms within a specific blockchain network, such as resource location through smart contracts, on-chain data structures, or protocols between nodes. Some existing resource addressing methods include:

[0011] a) Smart contract address: In some blockchain platforms (such as Ethereum), smart contract addresses are used to identify and access specific on-chain resources. However, this method is usually limited to a single blockchain network, and the readability of smart contract addresses is poor, which is not conducive to human users.

[0012] b) Decentralized domain name services: Projects such as ENS (Ethereum Name Service) attempt to provide DNS-like services for blockchains, allowing users to access blockchain resources through friendly domain names. However, these services are mainly focused on specific blockchain platforms and lack cross-chain operation capabilities. Summary of the invention

[0026] Furthermore, the recursive service node sends a resolution request to the subchain or resolver according to the feedback information of the root zone main chain; when sending a resolution request to the subchain, the subchain performs a matching query on the specific field of the blockchain data resource identifier according to the local management file, and feeds back the corresponding resolver address to the recursive service node; when sending a resolution request to the resolver, the resolver performs a matching query on the specific field of the blockchain data resource identifier according to the local management file, and feeds back the corresponding resolver address to the recursive service node, and the recursive service node feeds back the resolution information returned by the resolver to the client, and updates the local cache at the same time.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below through specific embodiments and drawings.

[0044] The present invention can solve the cross-chain addressing and parsing efficiency problems of data resources on the blockchain. Aiming at the application problems of the table-based data addressing method mainly adopted by the traditional data system set, such as the prominent addressing efficiency problems when the data is scattered, diverse, and large in scale, the present invention is based on the distributed and decentralized architecture of the blockchain, combined with DNS recursive resolution, data addressing and cache optimization methods, etc., which can effectively meet the application needs of new data resources such as distributed storage systems and cloud services. The main contents of the present invention include:

[0045] 1) Realize cross-blockchain resource addressing and resolution: This invention aims to break the isolation between different blockchain systems and realize cross-blockchain resource addressing and resolution by building a blockchain resource directory based on the hierarchical architecture of the Domain Name System (DNS). This will enable users to easily access resources distributed on different blockchains through friendly domain names or paths, just like using traditional DNS.

[0046] 2) Enhance the interoperability of blockchain systems: By learning from the recursive query mechanism of DNS, the present invention will design a recursive query blockchain resource resolution method, so that users can gradually query the resource information on the target blockchain. This mechanism can not only improve the efficiency of resource resolution, but also effectively enhance the interoperability between different blockchain systems.

[0047] 3) Provide a unified and scalable resource directory: The present invention will introduce a unified resource directory system in the blockchain environment. The system will adopt a layered architecture, where each layer corresponds to a different blockchain or resources within the blockchain. This architecture will be highly scalable and can adapt to various types of blockchain systems (such as public chains, private chains, and alliance chains), and support future expansion and evolution.

[0048] The present invention proposes a blockchain resource directory addressing and resolution method based on the domain name system (DNS) architecture, aiming to create a resource resolution system suitable for the blockchain environment by drawing on the hierarchical architecture and recursive query mechanism of DNS. The system will solve the isolation problem of the current blockchain system, focusing on the design of recursive service nodes, main chains, subchains and resolver nodes to realize the addressing, resolution and access services of data resources on the blockchain. The data resources described in the present invention include but are not limited to identity certificates, smart contracts, wallet addresses, databases / tables, interface addresses and other forms.

[0049] The present invention proposes a blockchain resource directory addressing and parsing method based on the domain name system, and its main steps are as follows: Figure 1 As shown, the following steps are included:

[0050] S101: Establish recursive service nodes and DNS-based hierarchical architecture for blockchain resource directories;

[0051] The blockchain resource directory addressing system of the present invention adopts a hierarchical architecture similar to DNS, which mainly includes the following levels:

[0052] Root zone main chain: This is the highest level of the blockchain resource directory and is responsible for managing the resolution of top-level blockchain identifiers. The root zone main chain manages the address resolution of top-level blockchains through multiple root blockchain networks, but the root zone main chain identifier is hidden in the naming to simplify the user experience.

[0053] Subchain: A subchain represents a blockchain network for a specific industry, field, or organization, such as a blockchain network for the financial industry or a blockchain for a government department.

[0054] Parser: This is the most detailed level. The parser will perform local parsing file queries based on the corresponding fields in the blockchain data resource identifier and feedback the network address corresponding to the data resource to the recursive service node.

[0055] S102: Using recursive service nodes and a DNS-based hierarchical architecture, blockchain resource directory addressing and resolution are performed through a recursive query mechanism.

[0056] The present invention draws on the recursive query mechanism of DNS and designs a resource resolution method suitable for blockchain systems. When a user needs to access a blockchain resource, the client first sends a request to the recursive service node, which is responsible for querying information from data resource management nodes at all levels (root main chain, subchain and resolver node), which is mainly divided into the following steps:

[0057] (1) Local query: Perform a local query. If the query is successful, the result will be returned. If the query is unsuccessful, the query request will be sent to the root zone main chain.

[0058] (2) Root zone main chain query: The recursive service node first sends a query request to the root zone main chain, and the root zone main chain returns the access information of the blockchain network corresponding to the top-level blockchain identifier. This information includes the subchain identifier, node information (such as RPC URL), and smart contract address.

[0059] (3) Subchain query: The recursive service node further sends a query request to the secondary blockchain, i.e., the subchain, and the subchain returns access information of specific resources, including the resolver address, etc.

[0060] (4) Resource acquisition: The recursive service node sends the resolution request to the corresponding resolver. The resolver performs a local resolution file query based on the corresponding field in the blockchain data resource identifier and feeds back the network address corresponding to the data resource to the recursive service node. The recursive service node feeds back the resolution result to the user, completing the resolution process.

[0061] During the recursive query process, the records returned by the blockchain need to contain enough information so that the client can correctly resolve the resources on the target blockchain. The structure of the records returned by the blockchain includes the following key fields:

[0062] (1) Target blockchain identifier: a unique identifier of the target blockchain network, used to confirm the blockchain network being queried.

[0063] (2) Target blockchain access information: including the RPC URL and smart contract address of the target blockchain node, which helps the client connect to the target blockchain.

[0064] (3) Resolver Contract Address: Indicates the resolver contract address on the target blockchain. The client can obtain more detailed resource information by calling this contract.

[0065] (4) Other optional information: including sub-paths, additional information (such as resource metadata, permission verification information, etc.). The sub-path refers to the path of the sub-class resources contained in the current domain name path.

[0066] In one embodiment of the present invention, a scalable blockchain data resource recursive resolution and addressing method is designed in combination with blockchain technology and DNS domain name management system application. According to the data resource identifier, combined with the data resource identifier resolution service architecture, the addressing and resolution tasks can be allocated to different blockchain levels and resolution servers step by step to provide more efficient resolution services. The specific process is as follows:

[0067] 1) The user or application software initiates a blockchain data resource identifier resolution request to the recursive service node.

[0068] 2) The recursive service node queries the local cache; if the query is successful, the parsing result is directly fed back to the user; if the query is unsuccessful, the complete recursive parsing process is started, such as Figure 2 As shown;

[0069] 3) The recursive service node sends the above parsing request to the blockchain data resource service main chain. The main chain matches and queries the specific fields of the blockchain data resource identifier based on the local management file, and feeds back the corresponding sub-chain address or parser address to the recursive service node.

[0070] 4) The recursive service node sends a resolution request to the subchain or resolver based on the feedback information. When sending a resolution request to a subchain, the subchain matches and queries the specific fields of the blockchain data resource identifier based on the local management file, and feeds back the corresponding resolver address to the recursive service node; when sending a resolution request to the resolver, the resolver matches and queries the specific fields of the blockchain data resource identifier based on the local management file, and feeds back the corresponding resolver address to the recursive service node;

[0071] 5) The recursive service node feeds back the parsing information returned by the parser to the user and updates the local cache to achieve cache optimization;

[0072] 6) The user further accesses the corresponding blockchain data resources based on the analysis results.

[0073] In summary, the corresponding blockchain data resource addressing and parsing method in the present invention includes the following key points:

[0074] Combined with the DNS service infrastructure, users (devices) can independently configure their corresponding recursive service nodes, or automatically obtain the corresponding recursive service nodes through the DNS system;

[0075] The recursive service node can trigger the addressing and parsing process starting from the main chain according to the blockchain data resource identifier, which includes:

[0076] The root zone main chain can match and query specific fields of blockchain data resource identifiers based on its local management files, and feed back the corresponding subchain address or resolver address to the recursive service node; the local management file can be in the form of smart contracts, zone files, etc.

[0077] The subchain can match and query specific fields of blockchain data resource identifiers based on its local management files, and feed back the corresponding resolver address to the recursive service node;

[0078] The parser can feed back the final parsing results of blockchain data resources to the recursive service node;

[0079] The structural design of blockchain return records, including the selection of fields and their application in recursive query and resource resolution;

[0080] Users can further access data resources on the blockchain based on the parsing results fed back by the recursive service nodes.

[0081] Another embodiment of the present invention provides a blockchain resource directory addressing and parsing system based on a domain name system, such as Figure 3 As shown, the system includes a recursive service node 201 and a DNS-based hierarchical architecture 202; the DNS-based hierarchical architecture 202 includes a root zone main chain 203, a subchain 204, and a resolver 205; the recursive service node uses the DNS-based hierarchical architecture to perform blockchain resource directory addressing and resolution through a recursive query mechanism. The root zone main chain 203 manages the address resolution of the top blockchain through multiple root blockchain networks; the subchain 204 represents a blockchain network of a specific industry, field or organization; the resolver 205 performs local resolution file query according to the corresponding field in the blockchain data resource identifier, and feeds back the network address corresponding to the data resource to the recursive service node.

[0082] The specific implementation process of the root zone main chain, sub-chain, resolver and recursive query mechanism refers to the above description of the method of the present invention.

[0083] Another embodiment of the present invention provides a computer device, comprising a memory and a processor, wherein the memory stores a computer program, the computer program is configured to be executed by the processor, and the computer program comprises instructions for executing each step in the method of the present invention.
