Abstract

The disclosure provides a system registration method of Web3.0 based on a blockchain and a spatial information network system, which are applied to the spatial information network system. When the first consensus ground node receives a user registration request, the first consensus ground node generates a blockchain identity, determines auxiliary nodes, generates key fragments respectively by the auxiliary nodes, generates a user public and private key pair by the client and the first consensus ground node based on system parameters and the key fragments, generates user certification information of the mobile user based on the public key and the blockchain identity of the user public and private key pair, and stores the user certification information in the blockchain. The scientific screening of the auxiliary nodes is realized through the performance adaptation, so that not only is the efficiency bottleneck that a single node bears overweight avoided, but also the traditional centralized mechanism is replaced by a distributed key fragment generation mode, the single-point fault risk and the probability of the whole key being attacked are greatly reduced, meanwhile, the calculation pressure is dispersed, and the key generation efficiency and safety are improved.
