An automatic node adding method of a blockchain integrated station, comprising: receiving, by the blockchain integrated station, a configuration instruction after accessing a blockchain network, and configuring 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 respectively according to the configuration instruction; initiating, by the blockchain integrated station, an authentication request to the certificate authority center according to the first network address, and receiving a digital certificate returned by the certificate authority center after the certificate authority center determines the authentication request passes verification; sending, by the blockchain integrated station, the digital certificate to the first blockchain node according to the second network address, wherein the digital certificate is used to trigger the first blockchain node to add the blockchain integrated station as a newly-added blockchain node in the blockchain network, receiving, by the blockchain integrated station, inquiry information from a second blockchain node in the blockchain network, wherein the inquiry information is generated and sent by the second blockchain node after automatically discovering the blockchain integrated station; and sending, by the blockchain integrated station, the digital certificate to the second blockchain node, wherein the digital certificate is used to trigger the second blockchain node to add the blockchain integrated station as a newly-added blockchain node in the blockchain network. receiving, by the blockchain integrated station, a configuration instruction after accessing a blockchain network, and configuring 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 respectively according to the configuration instruction; initiating, by the blockchain integrated station, an authentication request to the certificate authority center according to the first network address, and receiving a digital certificate returned by the certificate authority center after the certificate authority center determines the authentication request passes verification; sending, by the blockchain integrated station, the digital certificate to the first blockchain node according to the second network address, wherein the digital certificate is used to trigger the first blockchain node to add the blockchain integrated station as a newly-added blockchain node in the blockchain network, receiving, by the blockchain integrated station, inquiry information from a second blockchain node in the blockchain network, wherein the inquiry information is generated and sent by the second blockchain node after automatically discovering the blockchain integrated station; and sending, by the blockchain integrated station, the digital certificate to the second blockchain node, wherein the digital certificate is used to trigger the second blockchain node to add the blockchain integrated station as a newly-added blockchain node in the blockchain network.
