Description

Technical Field

[0001] This invention relates to the field of blockchain technology, and in particular to a blockchain domain name management method and system based on distributed digital identity. Background Technology

[0002] With the development of blockchain technology and the increasing number of application scenarios, cross-chain communication is becoming increasingly important. Data in different blockchain networks has different formats and storage methods, and they are highly isolated from each other. Cross-chain communication can break down the barriers between different chains, establish an effective interoperability mechanism, and enable different chains to work together to achieve more complex and diverse application scenarios. This is of great significance for promoting the overall development and innovation of blockchain technology.

[0003] With the increasing number of blockchains participating in cross-chain operations and the growing complexity of cross-chain networks, how to distinguish blockchains, identify resources within the network, and assign easy-to-remember, easy-to-use, and easy-to-lookup domain names to each participating blockchain has become a pressing issue. Traditional domain name management methods in cross-chain systems often hinder smooth cross-chain communication, including issues such as:

[0004] (1) The lack of a unified domain name management system: Traditional cross-chain technology records chain IDs without a unified domain name management system, which easily leads to confusion and management difficulties in blockchain domain names. The chaotic domain name management between homogeneous chains causes inconvenience to users;

[0005] (2) Centralization risk: The use of traditional domain name management systems may pose a centralization risk, causing issues with the credibility and transparency of domain name ownership. This could damage user trust and affect the security of cross-chain communication;

[0006] (3) Complex domain name transfer process: The traditional domain name transfer process is cumbersome, requiring users to communicate and operate with different domain name registrars. It may involve cumbersome procedures, long waiting times, and inconsistent standards among different institutions.

[0007] The above issues seriously affect the effectiveness of cross-chain communication and user experience. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a blockchain domain name management method and system based on distributed digital identity, so as to solve or partially solve the problem that the lack of domain name management between blockchains affects cross-chain communication.

[0011] Step S1: Obtain the target domain name authenticity verification request from the source chain; after the verification is passed, generate domain name existence proof information and feed it back to the source chain.

[0012] Step S2: Obtain the source domain name authenticity verification request from the target chain. After verifying the distributed digital identity of the source chain and the existence proof information of the source domain name, the request is fed back to the target chain to complete the existence proof verification. The source domain name authenticity verification request includes the domain name existence proof information, which is obtained from the cross-chain domain name management system.

By verifying the distributed digital identity of the target chain, determine whether the target domain name is legitimate. If the domain name does not exist on the target chain, proceed to step S102. If the target domain name is legitimate, generate domain name existence proof information and feed it back to the source chain.

[0018] As a preferred technical solution, the following are also included:

[0019] In step S3, in response to the successful verification in steps S1 and S2, the target chain performs the corresponding cross-chain business operation based on the cross-chain business information and writes the operation record into the target chain's ledger.

Attached Figure Description

[0033] Figure 1 This is a schematic diagram of blockchain domain name management based on distributed digital identity in the embodiment. Detailed Implementation

[0034] 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.

[0035] Example 1

[0036] To address the problems existing in the aforementioned prior art, this embodiment provides a blockchain domain name management method based on distributed digital identity, which is applied to a blockchain domain name management system. (See attached image.) Figure 1 The method mainly includes the following steps:

[0037] Step S1, Initiate cross-chain operation: Verify the authenticity of the target chain domain name in the cross-chain domain name management system to ensure the legality of the domain name, laying the foundation for subsequent cross-chain business.

[0038] S1.1, Check the authenticity of the target chain domain name: The system first checks whether the domain name on the target chain actually exists. This verification process is a prerequisite for cross-chain operations.

[0039] When a user on the target chain does not yet own a domain name on the target chain, the following steps are performed:

[0040] S1.2, Apply for a domain name: If the user does not already own a domain name on the target chain, they can apply for a new domain name in this step.

[0041] S1.3, Domain Name Issuance: After the domain name application is approved, a domain name is issued to the user to ensure its uniqueness in the cross-chain network.

[0042] Step S2, Source Chain Executes Cross-Chain Business: On the source chain, corresponding cross-chain operations are executed according to business needs. This can include asset transfer, data sharing, or other customized cross-chain services.

[0043] Step S3, Consensus Confirmation of Cross-Chain Information: After confirmation by the source chain's business execution and consensus mechanism, the relevant cross-chain information, including domain name existence proof and cross-chain business information, is sent to the cross-chain network. This step ensures the transparency and verifiability of cross-chain operations.

[0044] Step S4, Off-chain Secure Transmission and Authentication: Before the information is sent to the target chain, it undergoes a series of off-chain processes, including secure transmission, trusted authentication, and / or trusted computation, to ensure the security and accuracy of the information.

[0045] Step S5, Authenticity Verification: On the target chain, the authenticity of the domain name and cross-chain operation is verified again. This verification is automatically executed by the smart contract deployed on the target chain to prevent any possible fraudulent activities.

[0046] S5.1, Check the authenticity of the source chain domain name: The target chain verifies the existence certificate of the domain name provided by the source chain to ensure the authenticity of the domain name and the legality of cross-chain operations.

[0047] Step S6, the target chain executes cross-chain transactions: Once authentication is complete, the target chain will execute the corresponding cross-chain transaction operations. This may involve updating account information, processing transactions, and / or executing smart contracts.

[0048] Step S7, Data On-Chain: Finally, the result of the cross-chain operation is written into the ledger of the target chain. This step provides an immutable record for cross-chain transactions, ensuring the finality and transparency of the operation.

[0049] Through these steps, the cross-chain domain name management system ensures the authenticity of domain names while providing a secure, reliable, and efficient cross-chain business execution process. This method guarantees that blockchain domain names can identify resources in the blockchain cross-chain network, distinguish business blockchains, and provide memorability, ease of use, and network addressing.

[0050] Example 2

[0051] Building upon Example 1, this example provides a blockchain domain name management system based on distributed digital identity. It combines distributed authentication technology with blockchain domain name management in cross-chain processes to achieve secure and efficient cross-chain communication. The system includes the following main components:

[0052] Domain Name Application Module: This module is used for identity verification and credential issuance when blockchain users apply for domain names. If a blockchain user already possesses a distributed digital identity, they can apply by providing identity credentials. If they do not have a distributed digital identity, this module can help blockchain users automatically register a unique distributed digital identity across the entire network and issue corresponding credentials.

[0053] Domain Name Issuance Module: This module is used to issue distributed digital certificates based on digital certificates and unique domain names across the entire network for the blockchain. After the domain name application is approved, this module generates a digital certificate and binds it to the domain name to ensure its uniqueness and security.

[0054] Domain Name Query Module: This module includes domain name resolution and domain name query functions. Domain name resolution translates domain names into corresponding IP addresses, enabling users to access network resources associated with the domain name. The domain name query function is used to check the availability and ownership information of a domain name. This module replaces the traditional domain name-IP address mapping relationship with a domain name-distributed digital identity mapping relationship.

[0055] Domain Management Module: This module is used for managing domain names, including registration, changes, cancellation, and transfer. Users can use this module to register domain names, modify domain contact information, cancel unused domain names, or transfer domain names to other users.
