Abstract: The present invention discloses an SMA wire-driven reusable release mechanism having a self-resetting function. The present invention adopts a structure of two-stage load reduction and one-stage release. First-stage load reduction: a compression rod and a hoop petal, as well as an inclined block and a shell or a sliding block, all cooperate with each other by means of inclined surfaces, which can transfer most of tension load of the compression rod to the shell, leaving only a small part of the load transmitted to a thrust bearing. Second-state load reduction: balls in the thrust bearing are coated with a molybdenum disulfide lubricating coating, which can effectively reduce friction so as to reduce a torque transmitted to a driving shaft. First-stage release: the driving shaft drives a thrust bearing to rotate by a certain angle, causing an upper ring of the thrust bearing to descend to release a certain axial clearance.

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 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.

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.
