example 1

[0086] Such as Figure 5 As shown in , it is a schematic diagram of a domain name query process of a top-level domain name provided by the embodiment of the present application.

[0087] Nodes in sub-chains (such as Figure 5 The illustrated node 1) can be further configured to: acquire an initiating node (such as Figure 5 The top-level domain name to be queried sent by the shown node 0) determines the top-level domain name smart contract corresponding to the top-level domain name to be queried; if it is configured with the top-level domain name smart contract, call the top-level domain name smart contract to query the top-level domain name to be queried address information; if the top-level domain name smart contract is not configured, call the root domain name smart contract to query the node that owns the top-level domain name smart contract (such as Figure 5 The shown node 2) sends a contract call request to the node, and the contract call request includes the top-leve...

[0090] Such as Image 6 As shown, it is a schematic diagram of a domain name query process of a second-level domain name provided in the embodiment of the present application.

[0091] Nodes in sub-chains (such as Image 6 The illustrated node 1) can be further configured to: acquire an initiating node (such as Image 6 The shown node 0) sends the secondary domain name to be queried, and determines the application domain name smart contract corresponding to the secondary domain name to be queried; if it is configured with the application domain name smart contract, call the application domain name smart contract to query the query The address information of the second-level domain name; if the application domain name smart contract is not configured, determine the top-level domain name smart contract that manages the second-level domain name to be queried. If it is configured with the top-level domain name smart contract, call the top-level domain name smart contract to quer...

Abstract

This application provides a blockchain-based domain name query system and method. The system includes a public chain and a sub-chain composed of some nodes in the public chain. Among them, the nodes in the public chain are configured with the root domain name smart contract; the nodes in the sub-chain are configured to: generate a sub-domain name smart contract by executing the root domain name smart contract, and obtain the ownership of the sub-domain name smart contract through competition; and , obtain the domain name to be queried, and determine the first domain name smart contract corresponding to the domain name to be queried; if the first domain name smart contract is configured, call the first domain name smart contract to query the address information of the domain name to be queried. Compared with the domain name query system provided by this application, which uses fixed servers to manage different levels of domain names in the prior art, it has higher flexibility, is less vulnerable to attacks, improves the stability of the entire system, and can also improve participation and provide network Network Security of the Parties to the Services.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a domain name query system and method based on blockchain. Background technique [0002] A domain name is the name of a computer or computer group on the Internet consisting of a string of dot-separated names, which is used to identify the geographic location of the computer during data transmission. Domain names can be divided into different levels, including root domain name, top-level domain name and application domain name. Among them, the root domain name is the highest-level domain name node, for example, the domain name "." is the root domain name; the top-level domain name includes national top-level domain names and international top-level domain names, for example, the domain name ".com." The domain name under the domain name, for example, ".abc.com." or "www.abc.com." in the domain name is the application domain name. [0003] Domain name query is a necessary s...
