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.

Blockchain multi-party shared-governance-based system for maintaining domain name information

Provided in the embodiments of the present disclosure are a blockchain-based method and system for handling domain name abuse. All network nodes in a public blockchain can report domain name abuse, and all network nodes receiving reported data are entitled to participate in the process of judging whether domain name abuse exists in the reported data. The public blockchain obtains a target judgment result of whether domain name abuse exists by means of integrating first judgment results of multiple identification nodes on whether domain name abuse exists in the reported data and credit value of each identification node. Alternatively, when the number of identification nodes in the public blockchain is less than a preset number of nodes, a consortium blockchain composed of regulatory agencies directly judges whether domain name abuse exists in the reported data, and the judgment result serves as the target judgment result. Since the target judgment result is obtained through joint determination of nodes in the public blockchain or the consortium blockchain, the judgment result is not interfered by personal factors, with high accuracy and credibility, and thus the reported data is timely processed.

Provided are a method and an apparatus for resolving a domain name based on a co-governance chain. The method includes: determining data distribution nodes, and constructing a root domain name co-governance chain based on the data distribution nodes; obtaining trusted root zone data based on the root domain name co-governance chain, and constructing a co-governance root service based on the trusted root zone data; and resolving a domain name by applying a recursive resolution mode based on the co-governance root service and corresponding data in the root domain name co-governance chain, in response to receiving a domain name resolution request. With the root domain name co-governance chain, a decentralized processing mode is used, nodes are equal, and it is only required to make an adjustment in a certain node upon resolving a domain name, thereby avoiding risks such as single point management and centralization.
