Provided in the embodiments of the present application is a blockchain hybrid consensus-based system for maintaining domain name information. A gTLD blockchain is formed by first network nodes where international generic top-level domain registries are located, and a ccTLD blockchain is formed by second network nodes where various countries codes top-level domain registries are located. In each blockchain, various network nodes of the blockchain participate in the domain name information update process, so that the domain name information update process will not be affected by a mistake or an attack on one network node. Compared to centralized maintenance methods, this decentralized maintenance method is more secure and is beneficial to maintaining the stability of the system. International generic domain name information maintenance and country code domain name information maintenance are performed separately, and thus differences in information maintenance between local domain names and generic domain names are adapted and the efficiency of information maintenance is improved. In addition, domain name information is prevented from being maliciously tampered by means of blockchain technology and thus a reliable data source is provided for update of domain names.

Blockchain hybrid consensus-based system for maintaining domain name information

Provided by embodiments of the present application is a blockchain multi-party shared-governance-based system for maintaining domain name information, wherein a Root blockchain is formed by first network nodes where respective top-level domain registries are located, and domain name operation information needs to be confirmed by authoritative nodes among the first network nodes after a consensus process. Since the authoritative node is generated by means of voting by each first network node, each network node in the Root blockchain in the system participates in the consensus process for the domain name operation information. Through such a decentralized method for maintaining domain name information, the final state will not be affected by a mistake or an attack on one network node, resulting in higher security and better stability of the entire system compared to the centralized maintenance method. Furthermore, all the domain name operation information is stored in each first network node in the Root blockchain to prevent malicious tampering, and a reliable data source is provided for update of domain name.
