The blockchain integrated station configures, based on the configuration instruction, a first network address corresponding to a certificate authority center and a second network address corresponding to a first blockchain node in the blockchain network. The blockchain integrated station initiates an authentication request to the certificate authority center based on the first network address. The blockchain integrated station receives, from the certificate authority center, a digital certificate after the certificate authority center determines that the authentication request passes verification. The blockchain integrated station sends, based on the second network address, the digital certificate to the first blockchain node, where the digital certificate is used by the first blockchain node to add the blockchain integrated station as a new blockchain node in the blockchain network. ## Claims ### Claim 1 A blockchain integrated station comprising: at least one processor;
