Abstract: 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.

Abstract: 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.

Abstract: Provided are an identifier resolution method and apparatus for the Internet of Things. In the method, different identifier resolution systems are compatible through constructing an identifier resolution architecture for the Internet of Things, and a unified method is used for resolving various identifiers. Therefore, it is simply required to maintain one identifier resolution architecture for the Internet of Things when resolving different identifiers, which reduces the workload and difficulty for maintenance of the identifier resolution system and thus reduces the workload and difficulty for maintenance of the Internet of Things.

Abstract: 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.
