1. A method for issuing identity certificates, performed by a certificate authority system having multi-tier certificate authority nodes in a blockchain network, the method comprising:
issuing a first identity certificate to a first terminal as a blockchain node of the blockchain network through a first-tier certificate authority node from the multi-tier certificate authority nodes;
receiving a second identity certificate issuance request that is from the first terminal and that is made by using the first identity certificate;
issuing a second identity certificate to the first terminal through a second-tier certificate authority node from the multi-tier certificate authority nodes, wherein the first terminal forwards the second identity certificate to a second terminal as a blockchain node of the blockchain network;
receiving a third identity certificate issuance request that is from the second terminal and that is made by using the second identity certificate; and
issuing a third identity certificate to the second terminal through a third-tier certificate authority node from the multi-tier certificate authority nodes, wherein the second terminal forwards the third identity certificate to a third terminal as a blockchain node of the blockchain network.
