Patent attributes
A blockchain integrated station receives a first configuration instruction after accessing a certificate authority network. The blockchain integrated station initiates an authentication application to a certificate authority center of the certificate authority network based on a first network address indicated in the first configuration instruction. The blockchain integrated station receives a digital certificate from the certificate authority center after the certificate authority center determines that the authentication application passes verification. The blockchain integrated station receives a second configuration instruction after accessing a blockchain network. The blockchain integrated station sends the digital certificate to a first blockchain node in the blockchain network based on a second network address indicated in the second configuration instruction, where the digital certificate is used to trigger the first blockchain node to add the blockchain integrated station as a new blockchain node in the blockchain network.
