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

The invention provides a domain name query system and method based on a block chain. The system comprises a public chain and a sub-chain composed of part of nodes in the public chain. A root domain name smart contract is configured in a node in the public chain; nodes in the sub-chains are configured to generate sub-domain name smart contracts by executing the root domain name smart contracts andownership of the sub-domain name smart contracts is acquired in a competitive mode; a to-be-queried domain name is acquired, and a first domain name smart contract corresponding to the to-be-queried domain name is determined. the first domain name smart contract is called to query the address information of the to-be-queried domain name if the first domain name smart contract is configured in theto-be-queried domain name. Compared with the prior art in which domain names of different levels are managed by a fixed server, the domain name query system provided by the invention is higher in flexibility, is not liable to be attacked, improves the stability of the whole system, and further can improve the network security of all parties participating in and providing network 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...
